Description

Technical Field

[0001] The present invention relates to the technical field of excrement recovery and treatment, and in particular to a dehydration treatment device based on livestock excrement recovery and utilization. Background Art

[0002] The development of modern animal husbandry and the rise of factory-based intensive farming have enriched people's material needs, but have also brought about the proliferation of livestock wastewater, causing pollution to water sources, air, and the environment. In order to protect water sources, air, and the environment, livestock manure needs to be recycled and reused. In this process, livestock manure needs to be dehydrated and the raw manure and wastewater of poultry and livestock manure needs to be separated into liquid organic fertilizer and solid organic fertilizer.

[0003] Chinese patent application number CN2018106081814 discloses a feces processing device, comprising a housing, a drying mechanism disposed within the housing, support frames disposed on both sides of the housing sidewalls, and a material taking mechanism cooperating with the drying mechanism disposed on the support frames. The drying mechanism allows feces to be fed into the device, which then centrifuges the water contained in the feces to separate it, thereby achieving a solid-liquid separation effect. However, the device only utilizes the rotation of the drying mechanism for centrifugal dehydration, resulting in a relatively simple dehydration method and a relatively general solid-liquid separation effect. After centrifugal dehydration, some water will still remain in the material. Therefore, a dehydration treatment device that can effectively improve the dehydration effect is urgently needed. Summary of the Invention

[0004] The purpose of the present invention is to provide a dehydration treatment device based on the recycling and utilization of livestock manure, aiming to solve the above technical problems.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0017] Beneficial effects of the present invention:

[0018] The present invention utilizes the gravity change of the material in the dehydration cylinder before and after dehydration to cause the height position change of the gear sleeve. Before dehydration, the material presses down the movable plate, and the upper tooth groove is engaged with the first gear. At this time, the motor drives the dehydration cylinder to rotate. After dehydration, the material is reduced to move the movable plate upward, and the lower tooth groove is engaged with the second gear.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0031] See also Figure 1 and Figure 2 As shown, the present invention is a dehydration treatment device based on the recycling of livestock manure, which is characterized in that it includes a dehydration box 1, a centrifugal dehydration component 2 and an extrusion dehydration component 3 are arranged inside the dehydration box 1, a receiving groove 101 is arranged at the bottom of the dehydration box 1, a driving component 4 is arranged in the receiving groove 101, and the centrifugal dehydration component 2 and the extrusion dehydration component 3 are both connected to the driving component 4.

[0032] like Figure 4 As shown, the centrifugal dehydration assembly 2 includes a dehydration cylinder 201, a rotating column 202 and a first gear 203. The dehydration cylinder 201 is coaxially arranged inside the dehydration box 1. The rotating column 202 slides through the bottom of the dehydration cylinder 201, and the rotating column 202 rotates with the bottom of the dehydration box 1. The first gear 203 is fixedly sleeved on the bottom of the rotating column 202.

[0033] like Figure 5As shown, the extrusion and dehydration assembly 3 includes an extrusion roller 303, a central shaft 301 and a second gear 304. The central shaft 301 is arranged along the axis to pass through the rotating column 202. The top of the central shaft 301 extends into the dehydration cylinder 201. A plurality of brackets 302 are evenly arranged on the outside of the central shaft 301. The extrusion roller 303 is rotatably installed in the corresponding bracket 302, and the second gear 304 is fixedly sleeved on the bottom of the central shaft 301.

[0034] like Figure 6 As shown, the driving assembly 4 includes a movable disk 401, a positioning rod 402, a mounting ring 403, a support frame 404, a motor 405 and a gear sleeve 406. The movable disk 401 is adapted to be installed in the receiving groove 101, and the movable disk 401 is connected to the bottom of the receiving groove 101 through the spring 102. The upper end of the movable disk 401 is used to support the dehydration cylinder 201, the top of the positioning rod 402 is connected to the bottom of the movable disk 401, the bottom end of the positioning rod 402 passes through the receiving groove 101 and is fixedly connected to the mounting ring 403, the support frame 404 is fixedly connected to the bottom of the mounting ring 403, the motor 405 is fixedly set in the center of the support frame 404, and the gear sleeve 406 It is rotatably installed in the mounting ring 403, and the output end of the motor 405 is fixedly connected to the support plate 407, which is fixedly connected to the gear sleeve 406 through multiple connecting columns 408. The inner wall of the gear sleeve 406 is respectively provided with an upper tooth groove 4061 and a lower tooth groove 4062. The distance between the upper tooth groove 4061 and the lower tooth groove 4062 is greater than the distance between the first gear 203 and the second gear 304. The motor 405 drives the centrifugal drive component 4 to rotate through the tooth connection between the upper tooth groove 4061 and the first gear 203, and the motor 405 drives the extrusion and dehydration component 3 to rotate through the tooth connection between the lower tooth groove 4062 and the second gear 304.

[0035] Through the above technical solution, the driving component 4 utilizes the gravity change before and after the dehydration of the material in the dehydration cylinder 201 to make the gear sleeve 406 change its height position, so that the upper tooth groove 4061 and the lower tooth groove 4062 are respectively engaged with the first gear 203 and the second gear 304 in different dehydration stages, thereby realizing the switching between the centrifugal dehydration mode and the extrusion dehydration mode.

[0036] Specifically, such as Figure 7 and Figure 8As shown: when the livestock manure material is just added to the dehydration cylinder 201, the weight of the material in the dehydration cylinder 201 is relatively large, and the dehydration cylinder 201 will press down the movable plate 401 and squeeze the spring 102, so that the support frame 404, the motor 405 and the gear sleeve 406 move downward. At this time, the upper tooth groove 4061 is engaged with the first gear 203, and the second gear 304 is disengaged from the lower tooth groove 4062. The motor 405 will drive the rotating column 202 and the dehydration cylinder 201 to rotate, and the high-speed rotation of the dehydration cylinder 201 is used to achieve centrifugal dehydration; after a period of centrifugal dehydration, the moisture in the livestock manure material has been removed. Most of it, but a small part still remains in the material. At this time, the dehydration cylinder 201 reduces its overall weight due to the removal of water. The previously squeezed spring 102 will push the movable disk 401 upward to reset, causing the support frame 404, the motor 405 and the gear sleeve 406 to move upward. At this time, the first gear 203 disengages from the upper tooth groove 4061, and the lower tooth groove 4062 is meshed with the second gear 304. The motor 405 will now drive the central shaft 301 and the bracket 302 to rotate, and the squeezing roller 303 will cooperate with the inner wall of the dehydration cylinder 201 to roll and squeeze the material, thereby achieving squeezing dehydration of the material. The weight change of the livestock manure material before and after dehydration is utilized to achieve automatic switching between the two dehydration methods, and the coordination of centrifugal dehydration and squeezing dehydration can effectively improve the dehydration effect of the livestock manure material, which is beneficial to the subsequent recycling and utilization of the livestock manure material.

[0037] like Figure 4 As shown, longitudinal limit grooves 204 are arranged at equal intervals on the outside of the rotating column 202, and a hole for the rotating column 202 to pass through is provided at the bottom of the dehydration cylinder 201. Limit blocks 205 that are adapted to the longitudinal limit grooves 204 are arranged at equal intervals on the inner wall of the hole, and the limit blocks 205 are engaged in the longitudinal limit grooves 204.

[0038] Specifically, in order to enable the dehydration cylinder 201 to undergo lifting and lowering displacement changes relative to the rotating column 202, a limit block 205 is provided to be adapted to be clamped in the longitudinal limit groove 204, so that when the weight of the material changes, the dehydration cylinder 201 can slide along the longitudinal limit groove 204 through the limit block 205, and at the same time, the rotating column 202 will still drive the dehydration cylinder 201 to rotate when it rotates.

[0039] Furthermore, a plurality of dehydration holes 2011 are provided through the outer wall of the dehydration cylinder 201 , a feed cover plate 2012 is rotatably mounted on the upper end of the dehydration cylinder 201 , and an electrically controlled discharge port 2013 is provided at the bottom of the dehydration cylinder 201 .

[0040] Specifically, when the dehydration cylinder 201 rotates at high speed, the moisture in the livestock manure material can be centrifugally discharged through the dehydration hole 2011; the flipping of the feed cover 2012 can facilitate the insertion of materials, and at the same time, the feed cover 2012 can close the upper end opening of the dehydration cylinder 201 to prevent the dehydration cylinder 201 from being thrown out from the upper end opening when the dehydration cylinder 201 rotates centrifugally; the electric control discharge port 2013 is electrically connected to the background control system, and the opening and closing of the electric control discharge port 2013 can be controlled by the control switch, which is convenient for timely discharge of materials.

[0041] like Figure 3 As shown, a water trough 103 for collecting dewatered water and a material trough 104 for collecting discharged materials are provided at the bottom of the dehydration box 1. A drainage pipe 105 is connected to the water trough 103, and a discharge pipe 106 is connected to the material trough 104.

[0042] Specifically, the water removed by centrifugation will directly fall into the water trough 103 and then be discharged in time through the drain pipe 105. At the same time, the discharged material will directly fall into the material trough 104 and then be discharged in time through the discharge pipe 106. The independent separation design of the water trough 103 and the material trough 104 can prevent the removed water from seeping into the material, thereby ensuring the dehydration effect.

[0043] like Figure 5 As shown, a scraper 305 for discharging materials is provided at the bottom of the bracket 302 .

[0044] Specifically, to facilitate the extrusion of materials, a scraper plate 305 is provided at the bottom of the bracket 302. The scraper plate 305 can rotate with the central shaft 301, and during rotation, it continuously pushes the materials out of the electrically controlled discharge port 2013. In this embodiment, the length of the scraper plate 305 is consistent with the bottom radius of the dewatering drum 201, so that the scraper plate 305 can fully cover the bottom of the dewatering drum 201 during rotation. When switching to the extrusion dehydration mode, the dewatering drum 201 moves upward relative to the scraper plate 305, so that the scraper plate 305 is exactly against the bottom of the dewatering drum 201. This allows the scraper plate 305 to effectively push the materials out during rotation.

[0045] like Figure 6 As shown, an annular groove is provided on the upper end of the movable disk 401 , in which a plurality of balls 409 are rotatably installed. The dehydration cylinder 201 is rotatably installed on the upper end of the movable disk 401 through the balls 409 .

[0046] Specifically, in order to ensure the normal rotation of the dehydration cylinder 201, an annular groove and a ball 409 structure are provided, so that the dehydration cylinder 201 can rotate relative to the movable disk 401 through the ball 409, while at the same time not affecting the bearing effect of the movable disk 401 on the dehydration cylinder 201. The weight change of the material in the dehydration cylinder 201 can still be fed back to the movable disk 401 to cause it to move up and down.

[0047] like Figure 9 As shown, two parallel limiting plates 2021 are connected to the outside of the rotating column 202, and the two limiting plates 2021 are respectively clamped at the upper and lower ends of the bottom of the accommodating groove 101. A rotating groove 2022 is provided on the inside of the rotating column 202, and a rotating block 3011 is connected to the outside of the central axis 301. The central axis 301 is installed inside the rotating column 202 through the rotating block 3011 and coaxially rotates.

[0048] Specifically, the function of the limiting plate 2021 is to limit the height position of the rotating column 202, so that the rotating column 202 can only rotate circumferentially in the accommodating groove 101 and remain fixed in the height position. Similarly, the matching structure of the rotating block 3011 and the rotating groove 2022 is also to limit the height position of the central axis 301, and the central axis 301 can only rotate circumferentially in the rotating column 202, and cannot move axially relative to the rotating column 202.

[0049] like Figure 1 As shown, a plurality of equally spaced support legs 107 are fixedly connected to the bottom of the dehydration box 1 , and the support legs 107 are extended outward.

[0050] Specifically, the support legs 107 can support the dehydration box 1 to a certain height to facilitate drainage and discharging. At the same time, the outward expansion of the support legs 107 can effectively increase the supporting area of ​​the support legs 107, which is beneficial to improving the stability of the dehydration box 1.

[0051] The working principle of the present invention is as follows: when in use, the feed cover 2012 at the upper end of the dehydration cylinder 201 is opened, and the livestock manure material is added into the dehydration cylinder 201. At this time, the weight of the material in the dehydration cylinder 201 is large, and the dehydration cylinder 201 will press down the movable plate 401 and squeeze the spring 102, so that the support frame 404, the motor 405 and the gear sleeve 406 move downward. At this time, the upper tooth groove 4061 is meshed with the first gear 203, and the second gear 304 is disengaged from the lower tooth groove 4062. The motor 405 is started, which will drive the gear sleeve 406 to start rotating. The gear sleeve 406 drives the rotating column 202 and the dehydration cylinder 201 to rotate, and the high-speed rotation of the dehydration cylinder 201 is used to realize centrifugal dehydration; after a period of centrifugal dehydration, most of the moisture in the livestock manure material has been removed, but a small amount still remains in the material. At this time, the dehydration cylinder 201 reduces the overall weight due to the removal of moisture. The spring 102 that was squeezed previously will push the movable disk 401 upward to reset, causing the support frame 404, motor 405 and gear sleeve 406 to move upward. At this time, the first gear 203 disengages from the upper tooth groove 4061, and the lower tooth groove 4062 is gear-engaged with the second gear 304. The motor 405 will now drive the central shaft 301 and the bracket 302 to rotate, and the squeezing roller 303 will cooperate with the inner wall of the dewatering cylinder 201 to roll and squeeze the material to achieve squeezing and dehydration of the material. The dewatered water will fall directly into the water trough 103 and then be discharged in time through the drain pipe 105. When discharging, the scraper plate 305 is attached to the bottom of the dewatering cylinder 201 and rotates with the central shaft 301. During the rotation, the scraper plate 305 continuously pushes the material to fall from the electric control discharge port 2013, and directly falls into the material trough 104, and then is discharged in time through the discharge pipe 106.

[0052] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
