Description

Technical Field

[0001] The invention relates to the technical field of livestock and poultry manure water treatment, and in particular to a livestock and poultry manure water treatment device and a treatment method. Background Art

[0002] Livestock and poultry manure treatment refers to the collection, treatment and comprehensive utilization of manure and wastewater generated during livestock and poultry breeding to reduce environmental pollution, protect water resources, and promote resource recycling. Treatment methods usually include solid-liquid separation, anaerobic fermentation, aerobic treatment, biological filtration and other steps.

[0003] After searching, the Chinese patent with publication number CN114835360B includes a solid-liquid separation device, which includes a conveying cylinder, a conveying motor, a clamping assembly, a replacement assembly, a cleaning assembly and a discharging device. The conveying cylinder is provided with a feed port, and a spiral auger is rotatably connected inside the conveying cylinder. The spiral auger is fixedly connected to the output shaft of the conveying motor, and the conveying motor is fixedly connected to the conveying cylinder. The front end of the conveying cylinder is fixedly connected to a frame, and the front and rear sides of the frame are provided with discharge ports that coincide with the inner circle of the conveying cylinder.

[0004] In the above patent, the feces can be separated into solid and liquid by a solid-liquid separation device, and then the solid feces can be made into organic fertilizer, and the liquid feces can be sent to a biogas tank for fermentation. At the same time, the solid-liquid separation device can automatically replace and clean the filter regularly through the use of a compression component, a replacement component and a cleaning device, without the need for manual removal of the filter, and the maintenance time required is relatively short.

[0005] However, in the above patent, the solid feces after being squeezed and dehydrated are squeezed out from the gap between the discharge port and the cover plate. When the feces are stopped from being input into the feed port, the spiral auger is idle and cannot generate pressure on the feces in the inner cylinder. At this time, the pressure on the feces disappears and stops squeezing out. That is, some untreated feces always remain in the inner cylinder. This part of the residual feces will ferment and acidify after being left untreated for a long time, which will not only corrode the structure of the solid-liquid separation device but also endanger the surrounding environment.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1:

[0022] See also Figures 1 to 9 The present invention provides a technical solution: a livestock and poultry manure treatment device, comprising a support mechanism arranged on both sides of a fixed seat 1, a stirring assembly arranged on the support mechanism, a filter press assembly transmission-connected to the stirring assembly, and a cleaning assembly arranged on the filter press assembly, a guide plate 11 is fixedly connected to the top of the fixed seat 1, the outer contour of the guide plate 11 is set to be arc-shaped and a flow channel 12 is fixedly connected to both sides, a receiving groove 13 is fixedly connected to one side of the fixed seat 1, and one end of the flow channel 12 extends to the inside of the receiving groove 13; The support mechanism includes support columns 2 arranged on both sides of the fixed seat 1, T-shaped connecting rods 21 fixedly connected to the opposite surfaces of the top ends of the two support columns 2, and an L-shaped connecting rod 26 fixedly connected to the outer contour of the top end of one of the support columns 2. The top end of the support column 2 is provided with a slide groove, and the end of the L-shaped connecting rod 26 away from the support column 2 is fixedly connected to the stirring assembly; The stirring assembly comprises a feed cylinder 3 fixedly connected to an L-shaped connecting rod 26, the axis of the feed cylinder 3 is penetrated and connected to a stirring roller 31 for limited rotation, and the top end of the stirring roller 31 is drivingly connected to the filter press assembly; The filter press assembly includes a rotating shaft 4 that penetrates and is limitedly rotatably connected to the T-shaped connecting rod 21, and a filter press plate 46 that fits the outer contour of the guide plate 11. The side of the outer contour of the filter press plate 46 close to the L-shaped connecting rod 26 is transmission-connected to the cleaning assembly. The cleaning assembly includes a cleaning disc 5 for scraping and cleaning the outer contour of the filter press plate 46 . A notch is provided on the outer contour of the cleaning disc 5 , and a transmission shaft 51 is fixedly connected to the axis of the cleaning disc 5 .

[0023] In the present device, the stirring component completes the uniform mixing of the manure water to be treated and does not provide a power source for the entire device; the filter press component further realizes the solid-liquid separation operation of the manure water, and the separated liquid manure water flows into the storage tank 13 along the flow channel 12 to be stored, and the solid feces continue to be collected inside the filter cloth 25 for further filtration. After multiple filtrations, the water content of the solid feces is significantly reduced, thereby effectively improving the solid-liquid separation effect of the device; in this process, the cleaning component works synchronously to realize the rotation and cleaning of the filter press plate 46, thereby ensuring that during each filtration process, the contact part of the filter press plate 46 and the guide plate 11 is always in a clean state, thereby avoiding the filtration effect being affected by the solid feces adhering to the surface of the filter press plate 46.

[0024] At the same time, during the operation of the filter press assembly, the descending process of the fixed shaft 45 synchronously supports the filter cloth 25 and causes the tension of the filter cloth 25 and the bending angle at the bottom to change synchronously. As the fixed shaft 45 descends, the bending angle at the bottom of the filter cloth 25 increases synchronously. At this time, the sewage to be treated inside the filter cloth 25 is gradually concentrated, thereby further improving the working effect of the filter press assembly. Embodiment 2:

[0025] See also Figure 3-Figure 4 This embodiment further illustrates the following on the basis of the first embodiment: The top end of the inner contour of the support column 2 slide groove is fixedly connected with a tension spring 22, and the bottom end of the tension spring 22 is fixedly connected with a slider 23 slidably connected to the support column 2 slide groove, and the slider 23 is radially penetrated and fixedly connected with a winding roller 24, and the outer contour of the winding roller 24 is sleeved with a filter cloth 25 and the bottom end of the filter cloth 25 is flat on the outer contour of the guide plate 11 and the flow channel 12.

[0026] The bottom end of the stirring roller 31 is penetrated and slidably connected with a retracting roller 33, a paddle 36 is fixedly connected to the outer contour of the middle section of the stirring roller 31, an opening and closing plate 35 is rotatably connected to the upper limit of the outer contour of the retracting roller 33, a bevel gear 34 is fixedly connected to the bottom end of the retracting roller 33, and a compression spring 32 is fixedly connected between the top end of the retracting roller 33 and the inner contour of the stirring roller 31.

[0027] The stirring roller 31 is driven by an external motor and fixedly connected to the output shaft of the motor. A discharge groove is provided on the outer contour of the bottom end of the feeding cylinder 3 and the discharge groove corresponds to the position of the opening and closing plate 35 away from the end of the retracting roller 33 .

[0028] First, the manure to be treated is introduced into the interior of the feed barrel 3. At this time, the driving motor of the stirring roller 31 is turned on and the entire device is driven to start working. The specific working process of the stirring component is as follows: When the stirring roller 31 rotates, since the paddle 36 is fixedly connected to the outer contour of the middle section of the stirring roller 31, the paddle 36 rotates synchronously with the stirring roller 31 and completes the rotary cutting and stirring operation of the manure water to be treated inside the feeding barrel 3, thereby breaking up the large-sized solid feces in the manure water and achieving the purpose of uniform mixing. The mixed manure water can be more effectively filtered in the subsequent solid-liquid separation process, thereby improving the separation effect and working efficiency of the device.

[0029] At the same time, the stirring roller 31 synchronously drives the compression spring 32, the retracting roller 33 and the bevel gear 34 to rotate, while the opening and closing plate 35 cannot rotate due to the limiting effect of the inner wall of the feed barrel 3. At this time, the bevel gear 34 further realizes intermittent transmission to the cleaning component to control the starting state of the cleaning component, and the cleaning component synchronously resists the bevel gear 34 to rise and realize the discharging operation of the stirring component.

[0030] When the bevel gear 34 is squeezed and rises, the retracting roller 33 rises synchronously and shrinks inside the stirring roller 31. At this time, the opening and closing plate 35 rises synchronously and the compression spring 32 is compressed. The rise of the opening and closing plate 35 further makes it unable to block the discharge trough of the feed barrel 3. At this time, the mixed feces and water inside the feed barrel 3 are discharged along the discharge trough and fall into the inside of the L-shaped connecting rod 26; when the cleaning component descends, the retracting roller 33 drives the bevel gear 34 and the opening and closing plate 35 to descend synchronously under the resetting action of the compression spring 32. At this time, the opening and closing plate 35 blocks the discharge trough of the feed barrel 3 again, and the discharge operation of the feed barrel 3 is completed.

[0031] Since the cleaning component is in a reciprocating lifting state during the operation of the device, that is, the discharge operation of the feed barrel 3 is intermittent and the interval duration is related to the operating speed of the device, it can effectively avoid excessive discharge causing excessive burden on subsequent filtration separation operations, thereby affecting the working efficiency of the device, and the overall operating speed of the device can be controlled by adjusting the rotation speed of the stirring roller 31, which greatly reduces the difficulty of operating the device and effectively improves the degree of automation of the device. Embodiment three:

[0032] See also Figure 5-Figure 6 This embodiment further illustrates the following on the basis of the second embodiment: The top end of the rotating shaft 4 is connected to a transmission belt 41 which is sleeved on the outer contour of the top end of the stirring roller 31. A reciprocating threaded portion 42 is provided on the outer contour of the lower half of the rotating shaft 4. A transmission ring 43 passes through and is threadedly connected to the middle section of the rotating shaft 4. A positioning block 44 is fixedly connected to the outer contour of the transmission ring 43. A fixed shaft 45 is fixedly connected to the side of the positioning block 44 away from the feed barrel 3. The outer contour of the fixed shaft 45 passes through and is connected to a filter press plate 46 for limited rotation. Transmission grooves 47 are provided at the four corners of the filter press plate 46. An extension connecting rod 48 is fixedly connected to the side of the outer contour of the positioning block 44 close to the bevel gear 34.

[0033] The bottom of the fixed shaft 45 away from the positioning block 44 is pressed against the outer contour of the top of the filter cloth 25 . The four sides of the filter press plate 46 are all set to be arc-shaped and correspond to the outer contour size of the guide plate 11 .

[0034] As can be seen from the first embodiment, the stirring assembly is the power source of the entire device. When the stirring roller 31 rotates, the filter press assembly works synchronously. The specific working process of the filter press assembly is as follows: When the stirring roller 31 rotates, the rotating shaft 4 rotates synchronously under the transmission action of the transmission belt 41. At this time, the reciprocating threaded portion 42 rotates along with the rotating shaft 4. The transmission ring 43 begins to drive the positioning block 44 to descend along the axial direction of the rotating shaft 4 under the screw connection between it and the reciprocating threaded portion 42. Due to the setting of the reciprocating threaded portion 42, the transmission ring 43 descends along the axial direction of the rotating shaft 4 to the limit position and then begins to climb in the opposite direction under the extrusion action. After the transmission ring 43 rises a certain distance along the axial direction of the rotating shaft 4, the transmission ring 43 is disengaged from the reciprocating threaded portion 42. At this time, the transmission ring 43 stops rising and briefly stays at the top of the reciprocating threaded portion 42. Then, under the reset action of the compression spring 32, the transmission ring 43 is screwed again with the reciprocating threaded portion 42 and continues to descend, thereby realizing the reciprocating lifting process of the filter press assembly.

[0035] During this process, the bottom end of the filter press plate 46 is constantly in contact with and separated from the guide plate 11, and the filter cloth 25 passes between the filter press plate 46 and the guide plate 11, and the feces to be treated are piled up inside the filter cloth 25. Along with the squeezing between the filter press plate 46 and the guide plate 11, the feces to be treated are filtered to complete the solid-liquid separation operation, and the liquid feces flows into the flow channels 12 on both sides along the arc setting of the guide plate 11 and is further introduced into the receiving tank 13 to complete the collection and treatment of the liquid feces, while the solid feces continue to be piled up inside the filter cloth 25 for further filtration separation. The feces to be treated are filtered multiple times to effectively improve the separation quality of the device. The solid feces after multiple filtrations are piled on the surface of the filter cloth 25 and are centrally processed to facilitate collection by personnel.

[0036] On the other hand, during the reciprocating lifting of the positioning block 44, the extended connecting rod 48 accompanies the positioning block 44 and further drives the cleaning component to rise and fall synchronously, thereby realizing an intermittent transmission connection between the cleaning component and the stirring component, so that the cleaning component starts working only when the filter press component moves to the highest point, effectively ensuring the cleaning operation while further avoiding interference with the filter press operation.

[0037] It should be noted that during the reciprocating lifting and lowering process of the positioning block 44, it presses against the filter cloth 25 so that the filter cloth 25 is deformed synchronously. Since the filter cloth 25 is sleeved on the surface of the winding roller 24, during the descending process of the positioning block 44, the pressure on the filter cloth 25 increases, causing the middle section of the top of the filter cloth 25 to be concave and pull the winding rollers 24 on both sides. When the pulling force is less than the elastic coefficient of the tension spring 22, the winding roller 24 remains stationary. At this time, the descent of the positioning block 44 will cause the filter cloth 25 to slide on the surface of the winding roller 24, and the two sides of the bottom end of the filter cloth 25 are gradually tightened and the bending angle thereof is increased. At this time, the manure to be treated stacked inside the filter cloth 25 is concentrated in the middle section, that is, directly above the guide plate 11.

[0038] As the positioning block 44 further descends, the two sides of the bottom end of the filter press plate 46 come into contact with the inner walls of the two sides of the bottom end of the bent filter cloth 25 and are squeezed synchronously. At this time, the filter cloth 25 is pulled synchronously at both ends of the winding roller 24, which significantly increases the tension on the surface of the winding roller 24 and causes the tension spring 22 to be stretched, so that the winding roller 24 is accompanied by the slider 23 and descends inside the slide groove of the support column 2 and is synchronized with the positioning block 44. At this time, the further descent of the filter press plate 46 realizes the filtration operation of the sewage after centralized treatment inside the filter cloth 25. After centralized treatment, the filtration separation efficiency of the device can be effectively improved and the sewage can be further prevented from adhering to the two sides of the filter cloth 25 and affecting the separation quality of the device.

[0039] When the positioning block 44 rises, the filter cloth 25, the slider 23 and the winding roller 24 are synchronously restored to their initial positions under the resetting action of the tension spring 22, thereby realizing reciprocating centralized treatment of the sewage to be treated along with the reciprocating lifting and lowering of the filter press assembly. Embodiment 4:

[0040] See also Figure 7-Figure 8 This embodiment further illustrates the following on the basis of the third embodiment: The cleaning disc 5 is fitted to one side of the outer contour of the filter press plate 46, and the end of the transmission shaft 51 close to the bevel gear 34 is penetrated by and fixedly connected with a positioning shaft 52, and the end of the positioning shaft 52 away from the transmission shaft 51 is fixedly connected with a bevel gear 2 53 intermittently meshed with and transmission connected to the bevel gear 34, the middle section of the positioning shaft 52 penetrates and is limitedly rotated and connected to the end of the extension connecting rod 48 away from the positioning block 44, and a sleeve 54 is fixedly connected at the position of the notch of the cleaning disc 5 on the outer contour of the transmission shaft 51, and a transmission roller 56 is slidably connected to the inner contour of the transmission shaft 51. The size of the transmission roller 56 corresponds to the opening size of the transmission groove 47, and a return spring 55 is fixedly connected between the top of the transmission roller 56 and the inner contour of the sleeve 54.

[0041] It can be seen from the third embodiment that when the filter press assembly runs to the highest point, the cleaning assembly starts to work under the transmission action of the stirring assembly and realizes the rotational cleaning of the fixed shaft 45. The specific working process of the cleaning assembly is as follows: During the rising process of the positioning block 44, the extending connecting rod 48 drives the positioning shaft 52 and further controls the cleaning assembly to rise synchronously as a whole. When the positioning block 44 is close to the highest point, the bevel gear 2 53 is meshed with the bevel gear 1 34 and is connected by transmission. At this time, the bevel gear 1 34 drives the bevel gear 2 53 and further controls the cleaning assembly to rotate synchronously as a whole. At this time, the rotation of the cleaning disc 5 realizes the cleaning operation of the outer contour of the side of the filter press plate 46, and along with the rotation of the transmission shaft 51, the sleeve 54, the return spring 55 and the transmission roller 56 rotates synchronously. When the transmission roller 56 rotates until it comes into contact with the transmission groove 47, the rotation of the transmission roller 56 synchronously drives the filter press plate 46 to rotate along the fixed axis 45 under the limiting action of the transmission groove 47. Since the transmission groove 47 is arranged at the four corners of the filter press plate 46, that is, the interval angle of the transmission groove 47 is fixed to ninety degrees, the single rotation angle of the filter press plate 46 is fixed to ninety degrees, so that the bottom end surface of the filter press plate 46 that has just completed the filtration action is rotated to the side, and the cleaning operation is further completed by the cleaning disc 5.

[0042] At the same time, the positioning block 44 rises further, and the bevel gear 2 53 resists the bevel gear 1 34 and rises synchronously. It can be seen from Example 2 that this process completes the intermittent discharge step of the stirring assembly. When the positioning block 44 rises to the highest point, the compression spring 32 is compressed to the limit. At this time, the elastic potential energy of the compression spring 32 reaches the maximum. Under the joint action of the compression spring 32 and the positioning block 44's own gravity, the transmission ring 43 and the reciprocating threaded portion 42 are screwed together again. At this time, the rotation of the rotating shaft 4 drives the positioning block 44 to start to descend, thereby effectively improving the degree of automation of the device. Embodiment five:

[0043] See also Fig. 9 This embodiment further illustrates the following on the basis of the fourth embodiment: A method for treating livestock and poultry manure comprises the following steps: S1. Feeding and stirring: The livestock and poultry manure to be treated is introduced into the stirring component, and then the motor is turned on to drive the stirring component to rotate. The stirring component completes the operation of uniformly mixing the manure and water while driving the rest of the device to work synchronously; S2, adaptive aggregation: along with the transmission of the stirring assembly, the filter press assembly works synchronously and starts to reciprocate and rise and fall. During the descent of the filter press assembly, it squeezes the filter cloth 25 and causes the deflection angle of the bottom of the filter cloth 25 to change synchronously. During the ascent of the filter press assembly, it squeezes the bevel gear 1 34 and drives the opening and closing plate 35 to rise synchronously to complete the discharge operation of the stirring assembly. The released mixed manure and water fall into the filter cloth 25 and are automatically collected at the corresponding position of the top of the guide plate 11 under the action of the deflection angle of the filter cloth 25; S3, filter press separation: during the descending process of the filter press assembly, the filter press plate 46 and the guide plate 11 are in reciprocating contact and abutment with each other, at which time the feces and water inside the filter cloth 25 are fully squeezed and the solid-liquid separation operation is completed; S4. Cleaning the filter plate: During the ascending process of the filter press assembly, the cleaning assembly is intermittently meshed and transmission-connected with the stirring assembly. At this time, the cleaning assembly further drives the filter press plate 46 to rotate to complete the cleaning operation of the outer surface of the filter press plate 46.

[0044] After the manure water to be treated is introduced into the feed barrel 3, the rotation speed of the stirring roller 31 can be freely adjusted according to actual needs to control the overall working rate of the device, and the stirring component automatically completes the uniform mixing and intermittent discharge of the manure water; the released mixed manure water is piled up inside the filter cloth 25 and is centrally treated multiple times under the action of the filter press component, and the filter press component further realizes the reciprocating filter press separation operation, and the cleaning component is fixed when the filter press component runs to the highest point to start working and realize the rotation cleaning operation of the filter press component.
