How to Produce Durable Fertilizer Dehydrator?

 The organic fertilizer dehydrator is mainly composed of a screw, a cylindrical cage shell and a cone. The screw shaft and the output shaft of the reducer are connected by a flexible coupling. The following contents show the detailed composition of the fertilizer dehydrator.

　　 1. Screw

　　 The screw of fertilizer solid-liquid type of separator is composed of pitch threads and collars alternately sleeved on the screw shaft. Each thread and collar are respectively keyed on the screw shaft. Except for the first section (feeding area), which is a three-turn equal-distance continuous thread, the other sections are single-turn open, and the pitch of each pitch is different. It gradually decreases from the low-pressure side to the high-pressure side, and the diameter of the hub gradually increases. To increase the pressure, so as to squeeze out the water in the rubber.

　　2. Cylindrical energy shell

　The cylindrical energy shell is composed of a grate plate made up of cage bars fixed on the frame. The grate board is divided into 8 sections, each of which has different lengths. The inner diameter of the cylinder is 18 inches. It is divided into two halves on the vertical centiliter and fastened with bolts for easy removal for cleaning and maintenance. The cage bars that make up the castor board are separated by spring sheets to form longitudinal slits to allow water to flow out. There are scrapers on the skeletons on the upper and lower sides of the cylinder, corresponding to the position of the collar on the screw. Its function is to prevent the rubber from rotating with the screw, forcing the rubber to change the direction and position of the advancement, and forming a loose and porous shape. There are four jackets for heating or cooling on the outside of the cylinder, and the temperature in the machine can be controlled in zones according to dewatering craft requirements.


　　3. Cone

　　 This is a conical cylinder located in the discharge area, which can be moved back and forth to match the ring fixed on the screw shaft. The forward and backward movement of the cone is driven by a speed-adjusting motor through a gear composed of four jacks, and a manual adjustment mechanism is also provided. Through the back and forth movement of the cone, the area of orifice at the outlet is increased or decreased to change the pressure in the machine, thereby adjusting the dehydration rate of the solid-liquid type of dehydrating machine. After the rubber is extruded from the cone orifice, it is cut into small pieces by a cutter mounted on the screw shaft. Because the rubber is subjected to the shear and compression of the machine inside the machine to increase the temperature, the water in the rubber flashes when passing through the cone orifice, making the rubber loose and porous.

How does the solid-liquid dewatering equipment?

After the sludge is flocculated by the flocculant, a certain strength floc is formed. The solid-liquid mixture containing a large amount of free water enters the rotary filter through the overflow of the vertical reactor. Push forward and move forward, due to gravity for free dehydration. The rotation of the drum is opposite to that of the screw, so that the sludge is constantly tumbled in the drum, and the free water inside the flocs is continuously filtered out. The concentrated sludge is pushed out through the screw blades. The feed port enters the next level of dehydration process. After the dewatered sludge enters the screw extruder through the feed hopper, the sludge is compressed in volume under the action of the taper screw shaft and the variable diameter screw, thereby making the material liquid The water is quickly separated through the porous filter cartridge, and the water content of the solid material gradually decreases under the action of continuous compression to become the filter cake we need, and finally discharged out of the machine under the action of the screw. Consequently, the raw materials are dehydrated effectively.

Fertilizer production technology

Image
   Fertilizer production technology Here fertilizer production main refers to organic and compound fertilizer production. As we all know, fertilizer refers to a type of material that provides one or more essential nutrient elements for plants, improves soil properties, and improves soil fertility. It is one of the material foundations of agricultural production. So how to produce fertilzier? We will introuduce organic and compound fertilizer production technology. How to manufacture organic fertilzer? In summary, the organic fertilizer production process roughly includes: raw material selection (animal manure, straw, sludge, grass charcoal, etc.) → fermentation treatment → ingredient mixing → granulation → cooling and screening → metering and sealing →  finished product storage. 1. Select raw material. The raw materials of organic fertilizer production are vairous. You can use animal manure, straw, you can also use tea residue, biogas residue or sugar ...

The function of groove type compost turning machine in organic fertilizer production line

Image
In the organic fertilizer production line, the fermentation process of organic fertilizer is a very important link. The success of organic fertilizer fermentation directly determines the quality of organic fertilizer after granulation. The granulation of organic fertilizer mainly refers to the process of fermentation, throwing, crushing, drying, cooling and granulation of livestock manure after adding biological bacteria. There are mainly two types of tipping machine, one is trench type, the other is mobile type, and the other is mobile type, which covers a large area. Generally speaking, after the biological fermentation tank is built, the harmful bacteria in animal manure can be eliminated by adding biological bacteria, and then heating up quickly, deodorizing, and eliminating the harmful bacteria in the manure of livestock and poultry. Generally speaking, the tank type overturning machine is used to turn and toss several times a day, so that the unfermented materials are completely...
