Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production, in particular to a dehydrator with a wastewater filtering function. Background Art

[0002] Organic fertilizer is a fertilizer containing a lot of organic matter, usually derived from animal and plant waste, livestock and poultry manure, etc. Organic fertilizer can improve soil structure, promote microbial activity, enhance soil fertility, and increase crop yield and quality. Fertilizer production requires multiple processes, among which dehydration is one of the important steps in the production process.

[0003] According to a publicly disclosed dehydration equipment for fertilizer production (publication number: CN215766080U), in the above application, the inner wall of the shell can be cleaned by a cleaning mechanism and the cleaned sewage and debris impurities can be discharged together by opening the discharge pipe. The separated sewage and mixed fertilizer debris particles can be thoroughly cleaned to avoid dirt and grime inside the equipment, and the blockage of the dehydration holes can be avoided, thereby ensuring the normal operation of the equipment.

[0004] However, in actual use, the above equipment discharges sewage and debris impurities through the cleaning mechanism, but the wastewater lacks filtering function and the sources of waste include animal and plant waste and feces, etc. The raw materials inevitably contain some heavy metal impurities in the process of material collection, and direct discharge will have a certain impact on the environment, thereby causing a waste of resources; in view of this, we propose a dehydrator with wastewater filtering function. Utility Model Content

[0005] The purpose of the utility model is to provide a dehydrator with a wastewater filtering function to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dehydrator with wastewater filtering function, comprising a shell, a dehydration barrel is arranged inside the shell, a plurality of groups of filter holes are evenly opened on the surface and bottom of the dehydration barrel at equal distances, one end of a rotating shaft is fixedly connected to the bottom of the dehydration barrel, a motor is fixedly connected to the other end of the rotating shaft, a drain pipe is opened on the side wall of the shell, a filter box is penetrated at one end of the drain pipe away from the shell, a filter structure is arranged inside the filter box, and the filter structure includes:

[0007] A filter screen is provided inside the filter box, and the filter screen is installed through a circular frame. Two sets of receiving platforms are fixedly connected to the inner wall of the filter box, and the receiving platforms support the circular frame. Since the four sides of the circular frame fit the inner wall of the filter box and the inner wall of the box door, the filter screen can be stably placed inside the filter box for use, and is convenient for taking. An activated carbon layer is provided at the bottom of the filter screen. The outer wall of the filter box is fixedly connected to a second motor, and the output end of the second motor is fixedly connected to a reciprocating screw rod, and the outer wall of the reciprocating screw rod is threadedly connected to a threaded block;

[0008] A roller is rotatably connected to the surface of the threaded block, an electromagnetic coil is fixedly connected to the outer surface of the roller, a gear is fixedly connected to the outer surface of the roller, a rack is provided on the top of the gear, a groove is opened on the surface of the roller, a telescopic rod is fixed to the inner wall of the groove, a spring is provided on the outer wall of the telescopic rod, and one end of the spring is fixedly connected to a brush bundle.

[0009] Preferably, the outer wall of the threaded block on one side away from the rotating roller is attached to the inner wall of the filter box, and the filter box provides a limit for the threaded block.

[0010] Preferably, the rack is meshed with a gear, and the outer surface of the rack is fixedly connected to the inner wall of the filter box.

[0011] Preferably, one end of the telescopic rod away from the groove is fixedly connected with a brush bundle, the spring is sleeved on the outer wall of the telescopic rod, and the outer surface of the brush bundle is matched with the inner wall of the groove.

[0012] Preferably, one end of a support bar is fixedly connected to one side of the brush bundle close to the telescopic rod, and the other end of the support bar is slidably connected to the inside of the guide groove.

[0013] Preferably, the support bar is arranged in an L shape, and the guide groove is provided on the end surface of the roller away from the threaded block.

[0014] Compared with the prior art, the utility model provides a dehydrator with wastewater filtering function, which has the following beneficial effects:

[0015] 1. The dehydrator with wastewater filtering function discharges the wastewater of fertilizer discharged from the dehydration barrel to the inside of the filter box through a drain pipe. The wastewater is filtered through the filter screen and the activated carbon layer. The second motor drives the reciprocating screw to make the threaded block drive the roller to move back and forth. The gear drives the roller to rotate through the rack, so that the electromagnetic coil absorbs heavy metal impurities in the wastewater. The groove follows the roller to rotate one circle, and the brush bundle contacts the surface of the filter screen. The telescopic rod and the spring will be squeezed, so that the brush bundle can smooth the impurities blocked by the filter screen directly below the drain pipe, avoiding the reduction of filtration efficiency caused by excessive accumulation of impurities below the drain pipe. At the same time, the filtered wastewater can be reused to avoid waste of resources and avoid direct discharge to affect the environment.

[0016] 2. The dehydrator with wastewater filtering function provides auxiliary support force to the brush bundle by providing support bars. The support bars cooperate with the guide grooves to guide the brush bundle to move after being squeezed, thereby ensuring the stability of the brush bundle displacement.

[0025] In one embodiment of the utility model, the outer wall of the side of the threaded block 11 away from the roller 12 is attached to the inner wall of the filter box 6, the rack 15 is meshed with the gear 14, the outer surface of the rack 15 is fixedly connected to the inner wall of the filter box 6, the end of the telescopic rod 17 away from the groove 16 is fixedly connected to the brush bundle 19, the spring 18 is sleeved on the outer wall of the telescopic rod 17, the outer surface of the brush bundle 19 is adapted to the inner wall of the groove 16, the side of the brush bundle 19 close to the telescopic rod 17 is fixedly connected to one end of the support bar 20, the other end of the support bar 20 is slidably connected to the inside of the guide groove 21, the support bar 20 is arranged in an L shape, the guide groove 21 is opened on the end surface of the roller 12 away from the threaded block 11, the dewatering barrel 2 is driven by the motor 3 to rotate the rotating shaft 4 at a high speed so that it rotates inside the shell 1 to dehydrate the fertilizer, and the dehydrated waste water is discharged to the inside of the filter box 6 through the drain pipe 5, and the electromagnetic coil 13 can pass the electromagnet.

[0026] In the utility model, when in use, the waste water after fertilizer dehydration is discharged to the inside of the filter box 6 through the drain pipe 5, the filter screen 7 will block the impurities in the waste water, the activated carbon layer 8 will absorb the organic matter in the waste water, and finally the filtered waste water will be discharged through the waste water pipe opened in the filter box 6.
