Description

Technical Field

[0001] The utility model relates to the technical field of livestock waste treatment, in particular to a green and environmentally friendly livestock waste treatment device. Background Art

[0002] Aquaculture waste includes animal manure, urine, straw, by-products, etc. According to their different characteristics and composition, they can be divided into organic waste, solid waste and liquid waste. With the continuous expansion of animal husbandry and the increase of aquaculture waste, the effective treatment and utilization of these wastes has become an urgent task.

[0003] Therefore, a new solid-liquid separator for animal husbandry in the prior art (publication number: CN213167024U) is used by turning on the first motor and the second motor, rotating the pressure rod and the transmission rod, putting the waste into the funnel, and part of the liquid enters the liquid outlet bin. The other waste is sent into the device body through the transmission rod. The pressure rod transmits the waste downward, squeezes the waste during the transmission, and the liquid enters the liquid outlet bin through the isolation net. When the waste increases, the sliding column is pressed down to turn on the third motor, and the third motor drives the discharge tray to rotate, and the discharge tray discharges the waste from the discharge port.

[0004] However, during the downward movement of the discharge tray, in order to prevent the waste containing liquid from falling, the device needs to be in a shutdown state. Therefore, the waste dehydration time will be occupied during the shutdown process of the device, affecting the solid-liquid separation efficiency of the waste. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a green and environmentally friendly livestock waste treatment device, including a funnel and a dewatering box, an internal screw is rotatably connected in the dewatering box, an inner slider is threaded through the internal screw, an extrusion block is elastically connected to one side of the inner slider, a feed valve is connected between the funnel outlet and the dewatering box mouth, a valve plate is slidably connected in the feed valve, a connecting pin that penetrates the feed valve is fixedly connected to the side of the valve plate, an external spring is fixedly connected to the port of the connecting pin located outside the feed valve, the end face of the external spring away from the feed valve is fixedly connected to an external slider that slides horizontally along the length direction of the internal screw and synchronously with the inner slider, the side of the outer wall of the dewatering box away from the funnel is connected to a screw conveyor, and the screw in the screw conveyor extends into the dewatering box.

[0007] A further optimized solution of the utility model is as follows: an inner spring sleeved on the inner screw rod is fixedly connected between the inner sliding block and the extrusion block, and the extrusion block is sleeved on the inner screw rod.

[0009] A further optimization scheme of the utility model: the connecting shaft and the end on the same side of the internal screw both penetrate the outer wall of the dehydration box, and extend outward to be fixedly connected with a sprocket, and the two sprockets are driven by a chain.

[0010] A further optimized solution of the utility model is as follows: a filter plate is embedded in the bottom of the dehydration box on one side away from the funnel.

[0011] A further optimization solution of the utility model: the extrusion block is arranged in an L shape, and one side of the extrusion block is arranged as an arc-shaped depression that fits the spiral rod.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-4 As shown, a green and environmentally friendly livestock waste treatment device includes a funnel 8 and a dehydration box 1. An internal screw 11 is rotatably connected to the dehydration box 1, and an inner slider 13 is threadedly provided on the internal screw 11. An extrusion block 12 is elastically connected to one side of the inner slider 13. A feed valve 7 is connected between the outlet of the funnel 8 and the box port of the dehydration box 1. A valve plate 10 is slidably connected to the feed valve 7. A connecting pin 16 that penetrates the feed valve 7 is fixedly connected to the side of the valve plate 10. The port of the connecting pin 16 located outside the feed valve 7 is fixedly connected to an outer spring 6. The end surface of the outer spring 6 away from the feed valve 7 is fixedly connected to an outer slider 5 that slides horizontally along the length direction of the internal screw 11 and synchronously with the inner slider 13. The side of the outer wall of the dehydration box 1 away from the funnel 8 is connected to a screw conveyor 2, and the screw in the screw conveyor 2 extends into the dehydration box 1.

[0023] The above scheme achieves uninterrupted treatment of livestock waste in the following way:

[0024] The livestock waste enters the dehydration box 1 through the funnel 8 and the feed valve 7. The internal screw 11 rotates to realize the inner slider 13 driving the extrusion block 12 to move. The extrusion block 12 is used to extrude the livestock waste to achieve solid-liquid separation. The solid waste remaining in the dehydration box 1 is discharged through the discharge port of the screw conveyor 2 under the rotation of the screw conveyor 2.

[0025] In addition: when the inner slider 13 moves, the outer slider 5 moves synchronously, and pulls the outer spring 6 and the connecting pin 16 to move synchronously, thereby realizing that the valve plate 10 moves to close the feed valve 7, so that the extrusion block 12 moves to a position before being offset from the feed valve 7, ensuring that the feed valve 7 is in a closed state, preventing livestock waste from falling on the other side of the inner slider 13, and the outer spring 6 can be elastically stretched when the valve plate 10 closes the feed valve 7, ensuring that the outer slider 5 can continue to move.

[0026] like Figure 3 As shown, an inner spring 14 sleeved on the inner screw rod 11 is fixedly connected between the inner slider 13 and the extrusion block 12 , and the extrusion block 12 sleeved on the inner screw rod 11 .

[0027] The effect of the inner spring 14 provided in this solution is:

[0028] By utilizing the elastic contraction of the inner spring 14, when the waste is squeezed and dehydrated, the inner slider 13 forces the inner spring 14 to compress, thereby forcing the squeezing block 12 to squeeze the waste. The elastic compression of the inner spring 14 ensures that the squeezing and dehydrating time of the waste by the squeezing block 12 is extended, that is, before and after the squeezing and dehydration, the contact time between the squeezing block 12 and the waste block can be extended during the movement of the inner slider 13.

[0029] like Figure 3 As shown: the outer wall of the feed valve 7 is rotatably connected to an external screw 4 which is distributed in parallel with the internal screw 11 and has a thread passing through the outer slider 5; the end surface of the external screw 4 is fixedly connected to a connecting shaft 3 which passes through the dehydration box 1.

[0030] The connecting shaft 3 and the end of the inner screw 11 on the same side both penetrate the outer wall of the dehydration box 1 and extend outwards to be fixedly connected with a sprocket 9, and the two sprockets 9 are driven by a chain.

[0031] This scheme realizes the synchronous movement of the inner slider 13 and the outer slider 5 in the following way:

[0032] When the inner screw 11 rotates, the sprocket 9 on its end surface is driven to rotate, and then under the action of the chain, another sprocket 9 drives the connecting shaft 3 and the outer screw 4 to rotate, thereby realizing the movement of the outer slider 5;

[0033] In addition, the internal screw 11 of the present invention is driven by installing a motor on the outer wall of the dehydration box 1, and the connecting shaft 3 is arranged so that after the outer slider 5 moves to the connecting shaft 3 as the external screw 4 rotates, it will not move with the rotation of the connecting shaft 3, which can prevent the outer spring 6 from being stretched to a length exceeding the maximum stretching length of the outer spring 6.

[0034] like Figure 4 As shown: a filter plate 15 is embedded in the bottom of the dehydration box 1 on one side away from the funnel 8.

[0035] The present invention realizes dehydration of waste materials in the dehydration box 1 in the following way: the surface of the filter plate 15 is hollowed out, and the side facing the inside of the dehydration box 1 is covered with a filter screen, so as to ensure that the solid-liquid separation of the internal impurities is achieved under the extrusion of the extrusion block 12.

[0036] like Figure 4 As shown, the extrusion block 12 is L-shaped, and one side of the extrusion block 12 is an arc-shaped recessed setting that fits the spiral rod.

[0037] This scheme realizes the recycling of waste after extrusion as follows:

[0038] The solid waste dehydrated by the extrusion block 12 is concentrated at one end of the screw conveyor 2 in the dehydration box 1. The screw rod of the screw conveyor 2 rotates to transfer the solid waste into blocks to the discharge port and discharge it.

[0039] Working principle: livestock waste enters the dewatering box 1 through the funnel 8 and the feed valve 7, and the internal screw 11 is driven by the motor to rotate, so that the inner slider 13 drives the extrusion block 12 to move, and the extrusion block 12 is used to extrude the livestock waste to achieve solid-liquid separation. When the internal screw 11 rotates, it drives the sprocket 9 on its end face to rotate, and then under the action of the chain, another sprocket 9 drives the connecting shaft 3 and the external screw 4 to rotate, so as to realize the movement of the outer slider 5, and pull the outer spring 6 and the connecting pin 16 to move synchronously, so as to realize the movement of the valve plate 10 to close the feed valve 7, and the solid waste remaining in the dewatering box 1 is discharged through the discharge port of the screw conveyor 2 under the rotation of the screw conveyor 2.

[0040] The wiring diagram of the screw conveyor 2 in the present invention is common knowledge in the art, and its working principle is a known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the screw conveyor 2 are not explained in detail.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
