Description

Technical Field

[0001] The present invention relates to the technical field of solid-liquid separation, and in particular to a pressure filtration type cow dung solid-liquid separation device. Background Art

[0002] During the process of raising cattle in a farm, a large amount of cow dung is generated, and the cow dung is usually mixed with water and urine. In order to recycle the cow dung and reduce environmental pollution, the manure and sewage are usually collected first, and then the manure and sewage are uniformly subjected to extrusion dehydration treatment. The dehydrated manure and sewage can be used as organic fertilizers, production of seedling soil, etc.

[0003] In the existing related technical solutions, Chinese Patent CN215480475U discloses a cow dung dehydration treatment device. The cow dung dehydration treatment device includes a base; a separation box fixedly installed on the base; a support block fixedly installed on the base; a drying box fixedly installed on the top of the support block, with one side of the drying box fixedly connected to one side of the separation box; a feeding hopper fixedly installed on one side of the separation box; a U-shaped filter plate fixedly installed on the inner walls of both sides of the separation box; and a plurality of baking lamps fixedly installed on the inner wall of the top of the drying box. The cow dung dehydration treatment device provided by the present invention has the advantages of actively extruding feces and improving the dehydration efficiency.

[0004] For the above technical solution: The extrusion dehydration device usually needs to add a relatively large amount of cow dung at one time so that the cow dung can accumulate to a certain thickness for easy extrusion dehydration. However, since the separation plate is located at the bottom of the cow dung, it is difficult for the liquid in the upper and middle layers of the cow dung to fully flow out before extrusion. When extruding and dehydrating, it is necessary to slowly extrude to prevent the liquid from being difficult to discharge in time when the extrusion is too fast, resulting in deformation or damage of the device due to excessive pressure. And the slow extrusion method will reduce the dehydration efficiency. Summary of the Invention

[0005] In order to overcome the shortcoming that the liquid in the manure and sewage is difficult to fully flow out before extrusion when using the device in the prior art, resulting in the need for slow extrusion and reduced dehydration efficiency, the present invention provides a filter plate for pre-dehydration, and a structure for returning the cow dung to below the pressure plate after pre-dehydration; in order to be able to accelerate the efficiency of pressing the block, the formed cow dung block needs to be discharged from below the extrusion plate in time so that the next cow dung material can be quickly replenished below the extrusion plate.

[0015] Optionally, a diversion frame for guiding the liquid is fixedly connected to the support rod.

[0016] Compared with the prior art, the present invention has the following advantages: The present invention designs a filter plate for pre-dehydration and a structure that can return cow dung under the pressure plate after pre-dehydration, which can improve the efficiency of the pressing block. This device enables the manure to be spread over a large area to a relatively thin thickness in advance, so that the liquid in the manure can fully flow out before extrusion. However, spreading over a large area to a relatively thin thickness will require a large extrusion plate when squeezing again, and increasing the volume of the extrusion plate will make the equipment bulky. Therefore, a push plate, a side push plate, and a converging plate are used to converge from three directions, enabling the manure to be quickly converged to a certain thickness, which not only meets the requirement of discharging the liquid in advance but also meets the need to converge the manure to a certain thickness for squeezing. At the same time, the area of the extrusion plate can be designed to an appropriate size, and the extrusion plate can also perform extrusion at a relatively fast speed, improving the efficiency of extrusion dehydration, and helping to extend the service life of the device. Moreover, the filter press dehydration method can fully compress the cow dung, reducing the volume of the cow dung after dehydration and facilitating transportation and storage.

[0017] During the movement of the pushing plate, it can push the manure towards the direction of the lifting baffle. And the pushing plate moves the side pushing plate, enabling the active block and the driven plate to be extruded and cooperated to drive the two side closing plates to move relatively, realizing the function of gathering cow dung from three directions;

[0018] During the movement of the extrusion plate, the function of driving the sliding seat to move is realized through the extrusion cooperation of the roller and the guide plate, enabling the scraping plate to move above the cow dung. When the extrusion plate is reset, the roller will disengage from the guide plate, enabling the sliding seat to be reset under the push of the fourth spring and driving the scraping plate to push the cow dung off the filter plate. Thus, by using the action of the extrusion plate returning as the drive for the scraping plate, while the extrusion plate returns, the cow dung formed by the pressing block can be discharged and dropped.

[0019] During the movement of the extrusion plate, the function of driving the pushing plate to move is realized through transmission mechanisms such as the driving rack, driving gear, and transmission rod. And the transmission rod drives the jitter top block and the corrugated plate to be extruded and cooperated, causing the filter plate to jitter to improve the outflow rate of the liquid in the manure;

[0020] The front stop rod and the rear stop rod move by blocking the position control pull rod, enabling the position control rack and the position control gear to drive the scraping plate to switch states during the movement, so as to facilitate the scraping plate to move above the cow dung or scrape the cow dung. And the front buckle and the rear buckle are elastic buckles, which can not only fix the position control pull rod but also facilitate the position control pull rod to be inserted or disengaged.

Specific implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1: A pressure filtration type cow dung solid-liquid separation device, as Figures 1 - 4As shown in the figure, it includes a separation frame 1, support rods 101, filter plates 102, push plates 103, fixed rods 104, folding plates 105, first springs 106, side push plates 107, second springs 108, driven plates 109, driving blocks 110, lifting baffles 111, hydraulic cylinders 112 and extrusion plates 113. Two support rods 101 are symmetrically and fixedly connected to the separation frame 1. Filter plates 102 are installed on the support rods 101. The top of the filter plate 102 is connected to a push plate 103. The top of the support rod 101 is fixedly connected to a fixed rod 104. A folding plate 105 is slidably connected to the fixed rod 104 in the horizontal direction. The folding plate 105 is perpendicular to the direction of movement of the push plate 103. The folding plates 105 on the two fixed rods 104 are arranged oppositely. The lower end of the folding plate 105 contacts the top of the filter plate 102. A first spring 106 is sleeved on the guide rod of the folding plate 105. When the two folding plates 105 move relative to each other, the first spring 106 will be compressed. A side push plate 107 is slidably connected to the folding plate 105. The direction in which the side push plate 107 slides on the folding plate 105 is the same as the direction of movement of the push plate 103. A second spring 108 is sleeved on the guide rod of the side push plate 107. When the side push plate 107 slides away from the push plate 103, the second spring 108 will be compressed. A driven plate 109 is fixedly connected to the side push plate 107. Inclined surfaces are provided on the opposite sides of the two driven plates 109. Two driving blocks 110 are symmetrically and fixedly connected to the separation frame 1. Inclined surfaces are also provided on the sides of the driving blocks 110 close to the driven plates 109. The driving blocks 110 can drive the two folding plates 105 to move relative to each other by extruding the driven plates 109. A lifting baffle 111 is slidably connected to the support rod 101 in the vertical direction. The end face of the lifting baffle 111 is in close contact with the end of the filter plate 102 away from the push plate 103. During the movement of the push plate 103 towards the lifting baffle 111, it will push the side push plate 107 to slide in the same direction, so that the driving blocks 110 and the driven plates 109 can be in extrusion cooperation. A hydraulic cylinder 112 is fixedly provided on the upper side of the separation frame 1. An extrusion plate 113 is fixedly connected to the output shaft of the hydraulic cylinder 112. After the folding plates 105 and the push plates 103 are folded and combined, a frame-shaped space will be formed between them and the lifting baffle 111. This frame-shaped space is square, and the size of the extrusion plate 113 fits the square space.

[0032] The feces and sewage to be dehydrated are transported to the filter plate 102 using a feces pump in the prior art. The larger area of ​​the filter plate 102 can make the feces and sewage laid thinner, so that the liquid in the feces and sewage can fully flow out from the filter holes on the filter plate 102 before squeezing. Then the push plate 103 is controlled to move in the direction of the lifting baffle 111. The push plate 103 pushes the feces and sewage on the filter plate 102, and the push plate 103 pushes the two side push plates 107 during the movement, so that the side push plates 107 also move in the direction of the lifting baffle 111. During the movement of the two side push plates 107, the active block 110 will squeeze the driven plate 109, so that the two side push plates 107 can drive the two gathering plates 105 to move relative to each other, so that the spread cow dung is gathered to a certain thickness through the push plate 103, the side push plate 107 and the gathering plate 105, so as to facilitate extrusion and dehydration. During the above movement, the side push plate 107 and the gathering plate 105 will compress the first spring 106 and the second spring 108, and the hydraulic cylinder 112 will drive the squeezing plate 113 to move downward, and the squeezing plate 113 will squeeze and dehydrate the gathered cow dung. Water treatment, thereby separating the solid cow dung and the liquid, after the extrusion is completed, the hydraulic cylinder 112 is controlled to contract, and the pushing plate 103 is reset in the direction away from the lifting baffle 111, and the first spring 106 and the second spring 108 will push the side push plate 107 and the folding plate 105 to gradually reset, and then the lifting baffle 111 is controlled to move downward, so as to push the cow dung after dehydration from the filter plate 102; this device allows the dung to be spread over a large area to a thinner thickness first, so that the liquid in the dung can fully flow out before squeezing, and then Then, the pushing plate 103, the side pushing plate 107 and the gathering plate 105 are used to gather the manure from three directions, so that the manure can be quickly gathered to a certain thickness, which not only meets the need to fully discharge the liquid in advance, but also meets the need to gather the manure to a certain thickness for easy extrusion, so that the extrusion plate 113 can extrude at a faster speed, improves the efficiency of extrusion dehydration, and helps to extend the service life of the device. In addition, the use of a filter press dehydration method can fully compress the cow dung, reduce the volume of the cow dung after dehydration, and facilitate transportation and storage.

[0033] like Figure 1 , Figure 2 and Figure 5As shown in the figure, it further includes a transmission mechanism for driving the movement of the pushing plate 103. The transmission mechanism is connected to the extrusion plate 113. The transmission mechanism includes a transmission plate 2, a third spring 201, a transmission frame 202, a transmission rod 203, a transmission rack 204, a transmission gear 205, a first belt pulley 206, a driving frame 207, a second belt pulley 208, a transmission belt 209, a driving gear 210, and a driving rack 211. The transmission plate 2 is slidably connected to the pushing plate 103. A third spring 201 is sleeved on the guide rod of the pushing plate 103. When the transmission plate 2 approaches the pushing plate 103, the third spring 201 will be compressed. A transmission frame 202 is fixedly connected to the separation frame 1. The transmission rack 204 is slidably connected to the transmission frame 202 in the horizontal direction. The transmission rod 203 is fixedly connected to both the transmission rack 204 and the transmission plate 2. The transmission gear 205 and the first belt pulley 206 are coaxially rotatably connected to the transmission frame 202. The driving frame 207 is fixedly connected to the transmission frame 202. The hydraulic cylinder 112 is fixedly connected to the driving frame 207. And sliding plates for guiding are fixedly connected to both sides of the lifting baffle 111. One end of the sliding plate away from the lifting baffle 111 is slidably connected in the slideway opened inside the driving frame 207 in the vertical direction. The driving gear 210 and two second belt pulleys 208 are coaxially rotatably connected to the driving frame 207. The second belt pulley 208 and the first belt pulley 206 on the same side are jointly wound with the transmission belt 209. And the diameter of the second belt pulley 208 is larger than that of the first belt pulley 206. The driving rack 211 is fixedly connected to the extrusion plate 113. The driving rack 211 meshes with the driving gear 210.

[0034] When the extrusion plate 113 moves, it will drive the driving rack 211 to move synchronously. When the driving rack 211 moves downward, it will drive the transmission rack 204 to slide towards the lifting baffle 111 through the driving gear 210, the second belt pulley 208, the transmission belt 209, the first belt pulley 206, and the transmission gear 205, so that the transmission rack 204 pushes the pushing plate 103 towards the lifting baffle 111 through the transmission rod 203 and the transmission plate 2. When the end of the pushing plate 103 is in contact with the end of the folding plate 105, the pushing plate 103 cannot continue to move towards the lifting baffle 111. At this time, the extrusion plate 113 needs to continue to move downward to squeeze the folded feces and sewage. During this process, the third spring 201 will be compressed to provide a buffering effect; during the upward movement of the extrusion plate 113, it will drive the pushing plate 103 to move and reset away from the lifting baffle 111 through the transmission mechanism.

[0035] Embodiment 2: On the basis of Embodiment 1, as Figure 2 、 Figure 6 and Figure 7As shown in the figure, it further includes a scraping mechanism for pushing the dehydrated cow dung out of the filter plate 102. The scraping mechanism is connected to the extrusion plate 113. The scraping mechanism includes a sliding seat 3, a scraping support 302, a scraping plate 303 and an adjustment assembly. The lower end of the support rod 101 is slidably connected to the sliding seat 3 in the horizontal direction. A scraping support 302 is fixedly connected to the sliding seat 3. A scraping plate 303 is rotatably connected to the scraping support 302. An adjustment assembly is connected to the scraping plate 303. The adjustment assembly is used to rotate the scraping plate 303 to facilitate pushing the cow dung out of the filter plate 102.

[0036] During the upward movement of the extrusion plate 113, control the sliding seat 3 to slide in the direction of the lifting baffle 111, and control the lifting baffle 111 to move downward to avoid affecting the scraping of the cow dung. During this process, the scraping plate 303 is Figure 7 in the horizontal state shown in the figure. When the sliding seat 3 drives the scraping plate 303 and is about to move above the other end of the cow dung, since the cow dung will be extruded into blocks, the other end of the cow dung mentioned here refers to the end far from the lifting baffle 111. The adjustment assembly will drive the scraping plate 303 to rotate downward to the vertical state, and then make the sliding seat 3 drive the scraping plate 303 to reset in the direction away from the lifting baffle 111. The scraping plate 303 will then push the cow dung on the filter plate 102 away. The operator can place a conveyor belt below to convey the cow dung to the designated position. When the sliding seat 3 is about to complete the reset, the adjustment assembly will drive the scraping plate 303 to rotate and reset to the horizontal state to facilitate pushing the cow dung on the filter plate 102.

[0037] As Figure 2 、 Figure 3 、 Figure 7 and Figure 8 shown in the figure, the adjustment assembly includes a position control rack 4, a position control gear 401, a position control pull rod 402, a front buckle 403, a rear buckle 404, a rear stop rod 405 and a front stop rod 406. The position control rack 4 is slidably connected to the scraping support 302 in the horizontal direction. A position control gear 401 is fixedly connected to the rotating shaft of the scraping plate 303. The position control gear 401 meshes with the position control rack 4. A position control pull rod 402 is fixedly connected to the position control rack 4. The position control pull rod 402 is L-shaped. A front buckle 403 and a rear buckle 404 are fixedly connected to the scraping support 302. C-shaped slots are provided on both the front buckle 403 and the rear buckle 404. The front buckle 403 and the rear buckle 404 are arranged oppositely. The front buckle 403 and the rear buckle 404 are used to fix the position control pull rod 402 to prevent the scraping plate 303 from rotating randomly. Two rear stop rods 405 are symmetrically fixedly connected to the separation frame 1. The rear stop rods 405 are used to push the position control pull rod 402 forward to the front buckle 403. A front stop rod 406 is fixedly connected to the fixed rod 104. The front stop rod 406 is used to push the position control pull rod 402 backward to the rear buckle 404.

[0038] When the scraping plate 303 is about to move above the other end of the cow dung, the front stop bar 406 will block the control position pull rod 402 from continuing to move. Therefore, during the process of the sliding seat 3 driving the scraping plate 303 to continue moving, the control position pull rod 402 and the control position rack 4 will remain stationary. The control position pull rod 402 will disengage from the front snap 403 and move into the rear snap 404. The control position rack 4 will drive the scraping plate 303 to rotate counterclockwise by ninety degrees through the control position gear 401, so as to rotate the scraping plate 303 into a vertical state to facilitate scraping the cow dung from the filter plate 102 during the reset process; when the sliding seat 3 is about to complete the reset, the control position pull rod 402 will contact the rear stop bar 405. Therefore, during the process of the sliding seat 3 continuing to reset, the control position pull rod 402 will disengage from the rear snap 404 and move into the front snap 403, so that the control position rack 4 drives the scraping plate 303 to rotate clockwise and reset to the horizontal state through the control position gear 401; the front stop bar 406 and the rear stop bar 405 block the movement of the control position pull rod 402, so that the control position rack 4 and the control position gear 401 can drive the scraping plate 303 to switch states during the movement, so as to facilitate the scraping plate 303 to move above the cow dung or scrape the cow dung.

[0039] As Figure 7 and Figure 8 shown, both the front snap 403 and the rear snap 404 are elastic snaps, and the control position pull rod 402 will only snap into or disengage from the front snap 403 and the rear snap 404 when a relatively large force is applied to the control position pull rod 402.

[0040] By setting the front snap 403 and the rear snap 404 as elastic snaps, it is convenient for the control position pull rod 402 to automatically snap into or disengage during the movement of the sliding seat 3, and the control position pull rod 402 will not slide easily to ensure that the scraping plate 303 can clean the cow dung normally.

[0041] As Figure 2 、 Figure 5 、 Figure 6 and Figure 7As shown in the figure, it further includes a driving assembly for driving the sliding seat 3 to slide. The driving assembly is connected to the extrusion plate 113. The driving assembly includes a fourth spring 301, a guide plate 304, a connecting rod 305, a roller 306, a driven bracket 307, an adjusting guide rod 6 and a sixth spring 601. A fourth spring 301 is sleeved on the guide rod of the sliding seat 3. When the sliding seat 3 slides in the direction close to the pushing plate 103, the fourth spring 301 will be compressed. A guide plate 304 is fixedly connected to the scraping bracket 302. The guide plate 304 is inclined, and the end of the guide plate 304 close to the pushing plate 103 is lower than the other end. Two driven brackets 307 are symmetrically fixedly connected to the sliding plate of the extrusion plate 113. Two adjusting guide rods 6 are symmetrically fixedly connected to the driven brackets 307. A sixth spring 601 is sleeved on the adjusting guide rod 6. The connecting rod 305 is slidably connected to the adjusting guide rod 6. When the connecting rod 305 slides in the direction close to the driven bracket 307, the sixth spring 601 will be compressed. A roller 306 is rotatably connected to the lower side of the connecting rod 305. During the upward movement of the extrusion plate 113, the connecting rod 305 presses the guide plate 304 through the roller 306, causing the sliding seat 3 to move in the direction close to the pushing plate 103.

[0042] During the movement of the extrusion plate 113, the driven bracket 307 will move synchronously. During the downward movement of the driven bracket 307, the roller 306 will contact the inclined surface on the upper side of the guide plate 304. The guide plate 304 will press the connecting rod 305 in the direction of the driven bracket 307 through the roller 306, and the sixth spring 601 will be compressed. When the roller 306 moves below the guide plate 304, the sixth spring 601 will push the connecting rod 305 to reset, causing the roller 306 to move to the lower side of the guide plate 304. During the upward movement of the driven bracket 307, the roller 306 will press the inclined surface inside the guide plate 304, causing the guide plate 304 to drive the scraping bracket 302 and the sliding seat 3 to slide in the direction close to the lifting baffle 111, and the fourth spring 301 will be compressed. When the extrusion plate 113 drives the driven bracket 307 to complete the upward reset, the roller 306 and the guide plate 304 are disengaged, enabling the fourth spring 301 to push the sliding seat 3 to reset; during the movement of the extrusion plate 113, the function of driving the sliding seat 3 to move is realized through the extrusion cooperation of the roller 306 and the guide plate 304, enabling the scraping plate 303 to move above the cow dung. When the extrusion plate 113 completes the reset, the roller 306 will automatically disengage from the guide plate 304, enabling the sliding seat 3 to reset under the push of the fourth spring 301 and driving the scraping plate 303 to push the cow dung off the filter plate 102.

[0043] Embodiment 3: On the basis of Embodiment 2, as Figure 2 、 Figure 3 and Figure 4As shown, it also includes a shaking component for driving the filter plate 102 to shake, the shaking component is connected to the transmission rod 203, the shaking component includes a shaking slide bar 5, a fifth spring 501, a wave plate 502 and a shaking top block 503, a plurality of shaking slide bars 5 are symmetrically fixed on both sides of the filter plate 102, the shaking slide bar 5 is slidably connected to the support rod 101 on the same side, the fifth spring 501 is sleeved on the shaking slide bar 5, the end of the shaking slide bar 5 away from the filter plate 102 is fixedly connected to the wave plate 502, the lower side of the transmission rod 203 is fixedly connected to the shaking top block 503, Figure 2 It can be seen that the end of the shaking top block 503 away from the transmission rod 203 is a curved surface, and the shaking top blocks 503 on the two transmission rods 203 are staggered, so that the shaking top blocks 503 can alternately squeeze the wave plate 502 to the opposite side.

[0044] During the movement of the transmission rod 203, the shaking top blocks 503 on both sides will alternately squeeze the adjacent wave plates 502, so that the wave plates 502 can drive the filter plates 102 to shake back and forth, so as to increase the outflow rate of the liquid in the feces.

[0045] like Figure 6 As shown, it also includes a small support plate 7 and an electric push rod 701 for driving the lifting baffle 111. The small support plate 7 is fixedly connected to the two support rods 101, and the electric push rod 701 is fixedly connected to the small support plate 7. The telescopic axis of the electric push rod 701 is fixedly connected to the lifting baffle 111.

[0046] The extension and retraction of the electric push rod 701 can automatically control the lifting and lowering of the lifting baffle 111, so as to squeeze or push out the cow dung.

[0047] like Figure 6 As shown, a guide frame 8 is also included. The two support rods 101 are fixedly connected with the guide frame 8 . The guide frame 8 is located at the lower side of the filter plate 102 .

[0048] The liquid flowing downward from the filter plate 102 will fall into the guide frame 8 to facilitate centralized treatment of the liquid in the feces. When the device is actually produced, the lower end of the guide frame 8 can be set to a circular shape, and a pipe can be installed at the lower end of the guide frame 8 to direct the liquid out.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
