Description

Technical Field

[0001] This application relates to the field of manure treatment technology, specifically to a continuous dewatering treatment device and method for livestock manure. Background Technology

[0002] To prevent livestock manure from polluting the environment, farms typically treat livestock manure to render it harmless. Large-scale farms often use filter presses to dehydrate the manure wastewater. A patent with publication number CN118754383B discloses a dehydration device for livestock manure. In this device, when the arc-shaped extrusion block contacts the dehydration guide groove, the valve block moves downwards. This causes the extrusion dehydration plate to be forced downwards to dehydrate the manure slurry. When the manure slurry becomes thicker, the liquid further pushes the arc-shaped extrusion block upwards, causing the valve block to move further downwards. This increases the pressure of the extrusion dehydration plate on the manure slurry, further squeezing out the liquid from the thicker slurry, resulting in a more uniform moisture content in the dehydrated manure.

[0003] Although the existing equipment can process feces by squeezing, the squeezing and dehydration method requires waiting for the thickness of the fecal slurry to reach a predetermined value, there is a time interval between operations, and the feces are prone to being above the pressure plate during squeezing. The squeezed and dehydrated feces are easy to stick and difficult to discharge, which affects the efficiency of operation.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. Example 1

[0020] like Figures 1 to 4 As shown, this embodiment discloses a continuous dewatering treatment device for livestock manure, which includes a fixedly installed dewatering sleeve 200, a rotating roller 213, a central pressing block 209 with a squeezing zone, a receiving zone, and a shaking zone, two elastically installed squeezing sliders 207 in a squeezing chamber 208, and a filter assembly. The dewatering sleeve 200 is provided with a discharge port 205 and a receiving pipe 201; the rotating roller 213 is rotatably installed inside the dewatering sleeve 200, and the rotating roller 213 has a squeezing chamber 208; the central pressing block 209 is fixedly connected to the dewatering sleeve. On the cylinder 200, the central pressing block 209 is placed inside the extrusion chamber 208; the shaking area is set corresponding to the discharge port 205, and the receiving area is set corresponding to the receiving pipe 201; the extrusion slider 207 can slide back and forth along the direction set in the extrusion chamber 208, and the two extrusion sliders 207 are installed on both sides of the central pressing block 209; the filter assembly is set on the outer wall of the dewatering sleeve 200, and the filter assembly is set corresponding to the extrusion area; it is used to filter the filtrate after the extruded feces are extruded; wherein, the rotating roller 213 rotates, so that the extrusion slider 207 circulates in contact with the extrusion area, the receiving area and the shaking area.

[0021] In use, the continuous rotation of the rotating roller 213 causes the upper and lower extrusion sliders 207 to cycle through the extrusion zone to extrude the manure for dehydration, through the shaking zone to shake off the manure, and through the receiving zone to receive the manure. This cycle repeats continuously. As long as there is manure in the receiving pipe 201 of the dehydration sleeve 200, continuous dehydration processing can be achieved, improving work efficiency.

[0022] In some embodiments, a continuous dewatering treatment device for livestock manure is specifically designed as follows; like Figures 1-8As shown, this embodiment of the invention provides a continuous dewatering treatment device for livestock manure, including a crushing and processing box 100. A protective cover 102 is provided at the upper port of the crushing and processing box 100. A feeding chute 101 for guiding manure into the protective cover 102 is provided on one side of the protective cover 102. A drive motor 103 is fixedly installed on the side of the crushing and processing box 100. A crushing shaft 118 is provided at the output end of the drive motor 103. Crushing blades 117 for crushing manure are provided on the outer side of the crushing shaft 118. The crushing is driven by the drive motor 103. The shaft 118 rotates, and the crushing shaft 118 drives the crushing blade 117 to crush the feces entering the crushing and processing box 100, so that the cross section of the feces is broken down for subsequent dewatering. The crushing and processing box 100 is equipped with an auxiliary feeding component that causes the feeding slide 101 to vibrate up and down. The lower port of the crushing and processing box 100 is connected to the receiving pipe 201 at the upper end of the dewatering sleeve 200. The dewatering sleeve 200 is equipped with a dewatering component for dewatering the feces. The lower end of the dewatering sleeve 200 is equipped with a discharge port 205 for discharging the material. As attached Figure 4 As shown, the dehydration component includes a rotating roller 213 rotatably disposed inside the dehydration sleeve 200. The rotating roller 213 is connected to a dehydration drive assembly for driving its rotation. A squeezing chamber 208 is provided on the rotating roller 213 along the diameter direction. A squeezing slider 207 is slidably disposed at both ends of the squeezing chamber 208. The squeezing slider 207 and the ends of the squeezing chamber 208 form a receiving area 206. The receiving area 206 is positioned towards the receiving pipe 201 to complete the receiving. A squeezing guide assembly is provided in the squeezing chamber 208 to drive the squeezing slider 207 to move. Under the action of the squeezing guide assembly, the squeezing slider 207 will slide along the inner wall of the squeezing chamber 208, thereby providing power for the formation of the receiving area 206 and for the squeezing slider 207 to squeeze the feces. A filter assembly is provided on the outside of the dehydration sleeve 200, so that it can cooperate with the squeezing to complete the dehydration. As attached Figures 2 to 4 As shown, in this embodiment, the dehydration drive assembly includes a dehydration shaft fixedly connected to the center of the rotating roller 213. The outer end of the dehydration shaft is fixedly connected to the second gear 115. A transmission shaft 114 is rotatably provided above the second gear 115. A first gear 112 meshes with the second gear 115 on the transmission shaft 114. A second pulley 113 is provided at the outer end of the transmission shaft 114. A first pulley 105 is provided at the end of the crushing shaft 118. The first pulley 105 and the second pulley 113 are connected by a transmission belt 104. Under the drive of the crushing shaft 118, the first pulley 105 drives the second pulley 113 to rotate through the transmission belt 104. The second pulley 113 drives the first gear 112 to rotate. The first gear 112 drives the rotating roller 213 to rotate through the second gear 115, thus providing power for the rotating roller 213 to rotate. The diameter of the first gear 112 is smaller than the diameter of the second gear 115 in order to reduce speed; As attached Figures 5 to 8 As shown, the extrusion guide assembly includes a central pressing block 209 fixed at the center of the extrusion chamber 208. The central pressing block 209 is connected and fixed to the dewatering sleeve 200 via a fixed shaft 202. The rotating roller 213 has a through hole for the fixed shaft 202 to pass through. The central pressing block 209 has a receiving arc surface 211 (receiving area) on the upper side and an extrusion arc surface 210 (extrusion area) on the lower side. The radius of the extrusion arc surface 210 is larger than the radius of the receiving arc surface 211 to guide the extrusion slider 207 to move at different amplitudes. A reset slide rod 216 is fixedly provided at the inner end of the extrusion slider 207, and a sliding sleeve is provided on the outer side of the reset slide rod 216. The reset sleeve 215 is connected and fixed to the extrusion chamber 208 via a positioning rod. The reset sleeve 215 is connected to the extrusion slider 207 via a reset spring 214. A reset pressure wheel 217 is rotatably provided at the lower end of the reset slide rod 216. Under the action of the reset spring 214, the reset pressure wheel 217 presses against the surface of the central pressure block 209. Thus, when the reset pressure wheel 217 contacts the receiving arc surface 211, the receiving area 206 is formed. When the reset pressure wheel 217 contacts the extrusion arc surface 210, the reset pressure wheel 217 is pushed and then drives the extrusion slider 207 to move outward along the extrusion chamber 208. Multiple shaking protrusions 218 (shaking areas) are distributed at the lower end of the central pressing block 209. The shaking protrusions 218 correspond to the positions of the reset pressing wheel 217. When the reset pressing wheel 217 contacts the shaking protrusions 218, the reset slide rod 216 will drive the squeezing slider 207 to bounce so that the dehydrated feces can be discharged smoothly. As attached Figure 4 As shown, in this embodiment, the filter assembly includes a drain box 203 that communicates with the outside of the dehydration sleeve 200. The surface of the dehydration sleeve 200 where the drain box 203 is located is provided with an installation port. A filter baffle 212 is provided at the installation port. The filter baffle 212 matches the arc surface of the dehydration sleeve 200. The lower end of the drain box 203 is provided with a drain hopper 204 for draining water. When the feces are squeezed at the position of the filter baffle 212, the water in the feces will be squeezed into the drain box 203 and then discharged along the drain hopper 204. The outer end face of the extrusion slider 207 is arc-shaped and matches the inner wall of the dehydration sleeve 200 in order to achieve a rotary seal; The crushing and processing box 100 and the receiving pipe 201 are provided with a support component on the outside. The support component includes a vertically arranged vertical frame 302. The vertical frame 302 is connected to the outside of the crushing and processing box 100 and the dewatering sleeve 200 by a crossbar. A horizontal support 300 is provided at the lower end of the vertical frame 302. A reinforcing rib 301 for improving the mechanical structure is provided between the horizontal support 300 and the vertical frame 302. As attached Figure 1 and Figure 2 As shown, in this embodiment, the auxiliary feeding component includes a floating sleeve 120 fixedly disposed on the outside of the crushing and processing box 100. A floating vertical rod 121 is slidably disposed in the floating sleeve 120. The upper end of the floating vertical rod 121 is fixedly connected to the bottom of the feeding slide 101. The floating sleeve 120 and the feeding slide 101 are connected by a floating spring 119. A transmission side rod 122 is fixedly disposed on the side of the floating vertical rod 121. The transmission side rod 122 is connected to a reciprocating drive for driving it to move up and down. Under the action of the reciprocating drive, the floating vertical rod 121 moves up and down along the floating sleeve 120. The feeding slide 101 at the upper end of the floating vertical rod 121 will also bounce up and down. In this way, the feces entering the feeding slide 101 will quickly enter the crushing and processing box 100. The reciprocating drive includes a central shaft 110 fixed to the outside of the crushing and processing box 100. A transmission lever 106 is rotatably mounted on the central shaft 110. A transmission pin 111 is fixed at the end of the transmission lever 106. A waist-shaped sleeve 116 is provided at the end of the transmission side rod 122. The transmission pin 111 slides and matches with the rectangular groove in the waist-shaped sleeve 116. A vibrating wheel 108 is fixed at the end of the crushing shaft 118. Multiple vibrating protrusions 109 are arrayed on the outside of the vibrating wheel 108. The vibrating wheel 108 presses against the end of the transmission lever 106. When the vibrating wheel 108 rotates with the crushing shaft 118, the vibrating protrusions 109 will intermittently generate a pushing force on the transmission lever 106, thereby causing the transmission lever 106 to swing up and down. The transmission pin 111 at the end of the transmission lever 106 matches with the waist-shaped sleeve 116, thereby providing power for the up and down reciprocating motion of the transmission side rod 122. The transmission lever 106 has a rotating pressure wheel 0107 at its end, which corresponds to the position of the vibration protrusion 109. This allows the sliding friction between the transmission lever 106 and the vibration wheel 108 to be switched to rotational friction, reducing wear. Example 2

[0023] Based on the same inventive concept, this embodiment discloses a manure dehydration method implemented using the continuous dehydration treatment equipment for livestock manure in the above embodiments, comprising: Feces are placed into the receiving pipes 201 of the dewatering sleeves 200 and received by the upper extrusion slider 207; The rotating roller 213 is controlled to rotate, and the extrusion slider 207 moves along the outline of the receiving area of ​​the central pressure block 209, and the receiving pipe 201 moves the position of the feces; until the extrusion slider 207 transitions from the receiving area of ​​the central pressure block 209 to the extrusion area of ​​the central pressure block 209, the central pressure block 209 performs radial extrusion on the extrusion slider 207, continuously completing the extrusion and dehydration of the feces, and the water in the feces is filtered and discharged through the filter assembly; When the extrusion slider 207 passes through the shaking area of ​​the central pressing block 209, the shaking area and the elastically installed extrusion slider 207 cooperate to make the extrusion slider 207 shake and remove the pressed feces, and the feces are discharged along the discharge port 205; at the same time, the lower extrusion slider 207 moves to the receiving pipe 201 to receive the feces, realizing the reciprocating uninterrupted feces dehydration operation.

[0024] Working principle: In actual use, the feces are added into the feeding chute 101 by the tool to assist the feeding component. Under the action of the reciprocating drive, the floating vertical rod 121 moves up and down along the floating sleeve 120. The feeding chute 101 at the upper end of the floating vertical rod 121 will also bounce up and down. In this way, the feces entering the feeding chute 101 will quickly enter the crushing and processing box 100. At this time, the drive motor 103 drives the crushing shaft 118 to rotate, and the crushing shaft 118 drives the crushing blade 117 to rotate, thereby completing the cutting of the feces. The processed feces accumulate at the bottom of the receiving pipe 201. Driven by the crushing shaft 118, the first pulley 105 drives the second pulley 113 to rotate via the transmission belt 104. The second pulley 113 drives the first gear 112 to rotate, and the first gear 112 drives the rotating roller 213 to rotate via the second gear 115. This provides power for the rotating roller 213 to rotate. When the extrusion chamber 208 is facing upward, the feces at the bottom fill the receiving area 206. As the rotating roller 213 rotates, the receiving area 206, filled with feces, rotates. When the machine rotates to the position of the drain tank 203, under the guidance of the extrusion arc surface 210, the reset pressure roller 217 will drive the extrusion slider 207 to slide, thereby extruding the feces. The water in the feces will enter the drain tank 203 through the filter holes on the filter baffle 212, and the wastewater will be discharged through the drain hopper 204. As the rotating roller 213 continues to rotate, the dehydrated feces rotate to the bottom. At this time, the shaking protrusion 218 matches the reset pressure roller 217, causing the extrusion slider 207 to shake, thereby allowing the dehydrated feces to be discharged smoothly through the discharge port 205.
