Description

Technical Field

[0001] This utility model relates to the field of manure dehydration technology, and in particular to a dehydrator for livestock and poultry manure. Background Technology

[0002] Livestock farms generate large amounts of manure daily. Simply flushing it away without any treatment will cause significant environmental pollution and hinder resource conservation. For example, a chicken manure treatment machine can separate various types of raw livestock manure into liquid and solid organic fertilizers. The liquid organic fertilizer can be directly used by crops, while the solid organic fertilizer can be transported to nutrient-deficient areas to improve soil structure. Furthermore, it can be fermented into organic compound fertilizer.

[0003] According to the search, the patent (application number: 201820690759.0) discloses "a dehydrator for livestock and poultry manure". The device uses a spring, an annular baffle and a lead screw to control the length of the spring, thereby controlling the pressure required to push the annular cylinder backward. It has a good dehydration effect and can control the final water content of the manure.

[0004] However, as the feces are gradually squeezed and dehydrated, the device makes it easy for the feces to clump together into cakes inside the cylinder, increasing the difficulty of discharging the feces after it has clumped together. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a dewatering machine for livestock and poultry manure, which overcomes the shortcomings of the prior art and effectively solves the problem that as the manure is gradually squeezed and dehydrated, it is easy for the manure to clump together into cakes in the cylinder, which increases the difficulty of discharging the manure after it has clumped together.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dewatering machine for livestock and poultry manure includes a base plate, a conveying cylinder arranged above the base plate, and a spiral conveying roller rotatably connected inside the conveying cylinder. A filter shell is inserted and fixed at one bottom end of the conveying cylinder, and a dewatering mechanism is provided at one end of the conveying cylinder. The dewatering mechanism includes a fixed plate, a baffle fixed to the top of the back of the fixed plate, a connecting plate fixed to the top of the outer wall of one side of the fixed plate, a rotating rod rotatably connected to the outer wall of one side of the connecting plate, a mounting plate rotatably connected to one end of the rotating rod, a push rod motor mounted on the bottom of the outer wall of one side of the mounting plate, a push plate fixed to one end of the push rod motor, a connecting pipe sleeved and fixed to the wall of the rotating rod, connecting rods evenly distributed on the outer wall of the connecting pipes, and a discharge ring fixed to one end of the connecting rod.

[0008] Livestock manure is added to the conveying cylinder through the feed hopper. The first servo motor drives the spiral conveying roller to rotate, conveying and compressing the manure in the conveying cylinder towards the conical tube. The water that is squeezed out flows back along the conical tube to the filter shell and is discharged downwards to the external water tank for collection. As the manure is continuously conveyed and compressed, the dehydrated manure is gradually compressed into cakes and accumulates in the discharge ring. The second servo motor drives the rotating rod to rotate, which in turn causes the connecting pipe, connecting rod and discharge ring to rotate, so that different discharge rings are positioned between the baffle and the conical tube in sequence. When the discharge ring with the caked manure is on one side of the baffle, the push rod motor extends and retracts, and the push plate pushes the caked manure out of the discharge ring.

[0009] Preferably, support plates are fixed at both ends of the outer wall of the conveying cylinder, and support legs are fixed between the bottom of the support plates and the top of the base plate.

[0010] The position of the conveying cylinder is raised by the support plate and support legs to facilitate the collection of drainage after dehydration.

[0011] Preferably, a first servo motor is installed at the tail end of the conveying cylinder, and the output shaft of the first servo motor is connected and fixed to one end of the spiral conveying roller.

[0012] The first servo motor drives the spiral conveyor roller to rotate, conveying and compressing the feces in the conveyor cylinder.

[0013] Preferably, a feed hopper is inserted and fixed to the top of the conveying cylinder, and a tapered tube is fixed to one end of the conveying cylinder.

[0014] The feed hopper facilitates the entry of feces into the conveying cylinder, while the conical tube helps to squeeze and dehydrate the feces, allowing the water to flow towards the filter shell for discharge.

[0015] Preferably, the bottom end of the conveying cylinder is provided with a drain outlet that is compatible with the filter shell, and an external water tank is provided below the filter shell.

[0016] The squeezed and dehydrated water is discharged through the drain outlet and filter shell, and the discharged water is collected by an external water tank.

[0017] Preferably, a sealing sheet is adhered to one side of the outer wall of the baffle, and a sealing ring is adhered to the end of the tapered tube near the discharge ring.

[0018] The sealing performance between the discharge ring and the tapered tube and baffle is improved by using sealing plates and sealing rings.

[0019] Preferably, a second servo motor is installed on one outer wall of the connecting plate, and the output shaft of the second servo motor is fixedly connected to one end of the rotating rod.

[0020] The second servo motor drives the rotating rod to rotate, which in turn causes the connecting pipe, connecting rod and discharge ring to rotate, so that different discharge rings are positioned between the baffle and the tapered pipe in sequence.

[0021] The beneficial effects of this utility model are as follows:

[0022] The screw conveyor roller rotates, conveying and compressing the feces in the conveying cylinder towards the conical tube. As the feces are continuously conveyed and compressed, the dehydrated feces are gradually compressed into cakes that accumulate in the discharge ring. The rotating rod rotates, causing the connecting pipe, connecting rod, and discharge ring to rotate in sequence, so that different discharge rings are positioned between the baffle and the conical tube. When the discharge ring with the caked feces is on one side of the baffle, the push rod motor extends and retracts, using the push plate to push the caked feces out of the discharge ring. This effectively solves the problem in the existing technology where the feces easily clump together into cakes inside the cylinder as they are gradually compressed and dehydrated, increasing the difficulty of discharging the caked feces.
