Deodorizing device for livestock manure

Abstract

This utility model relates to the technical field of deodorization equipment, specifically to a deodorization device for poultry and livestock manure, comprising an upper tower body and a lower tower body. An exhaust pipe is installed at the top of the upper tower body, and support rods are fixedly installed in a ring at the lower end of the upper tower body. Through a middle tower shell assembly, the middle tower shell slides upward along an internal groove on the outer wall of the upper tower body, causing the lower end of the middle tower shell to detach from the upper nest of the lower tower body. At this point, the support frame is completely exposed, allowing the saturated activated carbon inside the support frame to be removed, cleaned, and replaced. Compared to traditional activated carbon adsorption towers with an integrated structure, this design avoids the need to disassemble the entire adsorption tower when replacing activated carbon, reducing cumbersome operation procedures and maintenance time. It also prevents excessive accumulation of odor in the accumulation area due to prolonged equipment downtime, thus preventing odor leakage and air pollution to the surrounding environment.

Description

Technical Field

[0001] This utility model relates to the technical field of deodorization equipment, specifically to a deodorization equipment for poultry and livestock manure. Background Technology

[0002] Animal manure deodorization equipment is an environmental protection device used in farms, manure treatment plants, and other similar locations. Its core function is to collect, purify, and treat the malodorous gases generated during the storage, stacking, and fermentation of animal manure, thereby reducing the pollution of the surrounding environment. With the rapid development of large-scale animal husbandry, a large amount of malodorous gases are generated during the stacking and fermentation of manure, mainly including ammonia, hydrogen sulfide, methanethiol, and volatile fatty acids. These gases not only pollute the surrounding atmospheric environment and affect the quality of life of residents, but also harm the health of farmers and do not meet relevant environmental emission standards.

[0003] In existing applications, odorous gases (mainly composed of ammonia, hydrogen sulfide, methanethiol, and volatile fatty acids) escaping from manure composting areas and septic tanks are collected using components such as sealed enclosures and negative pressure fans. These gases are typically trapped by activated carbon adsorption towers, which utilize the adsorption properties of porous adsorption materials. However, pollutants such as ammonia, hydrogen sulfide, and methanethiol in livestock manure gradually fill the pores of activated carbon. Once adsorption saturation is reached, the activated carbon loses its ability to trap odor molecules. Traditional activated carbon adsorption towers use a single, integrated structure, requiring disassembly for carbon replacement. This cumbersome process and low maintenance efficiency can lead to excessive odor accumulation in the accumulation area due to prolonged equipment downtime, potentially causing odor leakage and air pollution to the surrounding environment. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a deodorizing device for poultry and livestock manure, which can effectively solve the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a deodorizing device for poultry and livestock manure, comprising an upper tower body and a lower tower body. An exhaust pipe is provided at the top of the upper tower body, and support rods are fixedly installed in a ring at the lower end of the upper tower body. A support base is fixedly installed at the lower end of the lower tower body, and an air inlet pipe is fixedly installed on one side of the outer wall of the lower tower body. A middle tower shell assembly is provided between the upper tower body and the lower tower body. The mid-section tower shell assembly includes a mid-section tower shell and an internal sliding groove. The internal sliding groove is formed inside the outer wall of the upper half of the tower body, and the mid-section tower shell is slidably fitted inside the internal sliding groove of the upper half of the tower body.

[0006] Furthermore, a support frame is fixedly installed at the upper part of the lower half of the tower body. Airflow holes are opened at the bottom of the support frame. The inside of the support frame is filled with activated carbon material. The lower end of the middle tower shell is nested inside the upper end of the lower half of the tower body. The upper end of the lower half of the tower body is fixedly installed at the lower end of the support rod.

[0007] Furthermore, a guide groove is provided on one side of the inner wall of the upper half of the tower body, and a sliding block is slidably fitted inside the guide groove. One end of the sliding block is fixedly installed on the upper part of the outer wall of the bearing frame.

[0008] Furthermore, a lead screw is rotatably sleeved inside the guide groove, a bottom block is rotatably sleeved at the lower end of the lead screw, and the outer side of the lead screw is rotatably sleeved inside the guide groove.

[0009] Furthermore, a servo motor is fixedly installed at the upper end of the lead screw, a fixing plate is fixedly installed at the lower end of the servo motor, and the lower end of the fixing plate is fixedly installed on the cover plate at the upper end of the upper half of the tower body.

[0010] Furthermore, the output shaft of the servo motor passes through the interior of the fixed plate, and the output shaft of the servo motor is connected to the upper end of the lead screw.

[0011] Furthermore, a fixing groove is provided on the side of the upper tower body near the guide groove, and a sealing plate is fixedly installed on one side of the fixing groove.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model uses a servo motor in the middle section tower shell assembly to drive a lead screw to rotate. The lead screw rotates in a guide groove and drives a sliding block that is threadedly engaged with it to move upward along the guide groove. This, in turn, drives the support frame fixed on the sliding block to move upward synchronously. The middle section tower shell slides upward along the built-in sliding groove on the outer wall of the upper half of the tower body, causing the lower end of the middle section tower shell to detach from the upper end of the lower half of the tower body. At this time, the support frame is completely exposed to the outside, allowing the saturated activated carbon inside the support frame to be removed and cleaned or replaced. Compared with the traditional activated carbon adsorption tower with an integrated structure, this design avoids the need to disassemble the integrated adsorption tower to replace the activated carbon. This reduces the complexity of the operation process and the time-consuming and inefficient maintenance. It also prevents excessive accumulation of odor in the accumulation area due to long-term equipment downtime, thus preventing odor leakage and air pollution to the surrounding environment.

[0013] 2. At the same time, the sealing plate is fixedly installed on one side of the fixing groove to seal the gap at the connection between the upper half of the tower body and the guide groove, preventing external dust, water vapor and other impurities from entering the tower body and affecting the operation of the equipment. It can also prevent the leakage of odorous gases inside the tower body and ensure the overall sealing of the tower body. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example 1

[0020] Reference Figures 1 to 4This is the first embodiment of the present invention, disclosing a deodorizing device for poultry and livestock manure, comprising an upper tower body 1 and a lower tower body 2. An exhaust pipe 3 is provided at the top of the upper tower body 1, and support rods 11 are fixedly installed in a ring arrangement at the lower end of the upper tower body 1. A support base 5 is fixedly installed at the lower end of the lower tower body 2, and an air inlet pipe 4 is fixedly installed on one side of the outer wall of the lower tower body 2. A middle tower shell assembly 6 is provided between the upper tower body 1 and the lower tower body 2. Existing technology uses a sealing cover at the odor collection point (such as a manure fermentation tank or manure storage shed) and... A negative pressure fan is connected to the air inlet pipe 4. When the fan is running, a negative pressure environment is formed in the collection hood and the pipe, which forcibly draws in the dispersed odor and transports it to the lower tower body 2, the middle tower shell 61, and the upper tower body 1. The odor flows upward and enters the middle tower shell assembly 6 between the upper tower body 1 and the lower tower body 2. The assembly has a built-in support frame 12, and the support frame 12 is filled with activated carbon material 13. The pores of the activated carbon trap pollutants such as ammonia, hydrogen sulfide, and methanethiol in the odor. After the gas purification is completed, the purified gas is discharged from the outlet end of the upper tower body 1. The intermediate tower shell assembly 6 includes an intermediate tower shell 61 and an internal sliding groove 62. The internal sliding groove 62 is formed inside the outer wall of the upper tower body 1. The intermediate tower shell 61 is slidably fitted inside the internal sliding groove 62 of the upper tower body 1. When the intermediate tower shell 61 moves up and down, it moves up and down inside the internal sliding groove 62 of the upper tower body 1. When it moves upward, the activated carbon filling layer and the support frame 12 inside the intermediate tower shell 61 are exposed to the outside. The support frame 1 is fixedly installed at the upper part of the interior of the lower tower body 2. 2. Airflow holes 14 are provided at the bottom of the support frame 12. When the odor of animal manure flows upward from the inside of the lower half of the tower body 2, it enters the activated carbon filling layer through multiple airflow holes 14 at the bottom of the support frame 12. The pollutants such as ammonia, hydrogen sulfide, and methanethiol in the odor are intercepted through the pores of the activated carbon, thus completing the purification of animal manure odor. The inside of the support frame 12 is filled with activated carbon material 13. The lower end of the middle tower shell 61 is nested inside the upper end of the lower half of the tower body 2. The upper end of the lower half of the tower body 2 is fixedly installed at the lower end of the support rod 11.

[0021] A guide groove 67 is provided on one side of the inner wall of the upper half of the tower body 1. A sliding block 610 is slidably fitted inside the guide groove 67. One end of the sliding block 610 is fixedly installed on the upper part of the outer wall of the bearing frame 12. A lead screw 69 is rotatably fitted inside the guide groove 67. A bottom block 66 is rotatably fitted at the lower end of the lead screw 69. The outer side of the lead screw 69 is rotatably fitted inside the guide groove 67. A servo motor 63 is fixedly installed at the upper end of the lead screw 69. A fixing plate 64 is fixedly installed at the lower end of the servo motor 63. The lower end of the fixing plate 64 is fixedly installed on the cover plate at the upper end of the upper half of the tower body 1. The output shaft of the servo motor 63 passes through the interior of the fixing plate 64, and the output shaft of the servo motor 63 is connected to the upper end of the lead screw 69.

[0022] In use, once the activated carbon reaches adsorption saturation, first close the inlet and outlet valves of the adsorption tower to cut off the gas supply to be treated. Then, start the servo motor 63. The output shaft of the servo motor 63 drives the lead screw 69 to rotate. The lead screw 69 rotates in the guide groove 67 and drives the sliding block 610, which is threaded to it, to move upward along the guide groove 67. This, in turn, drives the support frame 12 fixed on the sliding block 610 to move upward synchronously. The middle tower shell 61 slides upward along the built-in sliding groove 62 on the outer wall of the upper half of the tower body 1, so that the lower end of the middle tower shell 61 is separated from the upper nested structure of the lower half of the tower body 2, completing the disassembly of the middle tower body. At this time, the support frame 12 is completely exposed. In this configuration, the operator can directly remove and clean the saturated activated carbon in the support frame 12, and then fill the support frame 12 with new activated carbon material. After the activated carbon is filled, the middle tower shell 61 is slid down along the built-in slide groove 62 so that its lower end is re-nested into the upper end of the lower tower body 2, thereby resetting the middle tower shell assembly 6. Compared with the traditional activated carbon adsorption tower with an integrated structure, this avoids the need to disassemble the integrated adsorption tower when replacing activated carbon, which can reduce the cumbersome operation process and the low maintenance efficiency and time consumption. It also avoids the excessive accumulation of odor in the accumulation area caused by long-term equipment shutdown, which could lead to odor leakage and prevent air pollution to the surrounding environment.

[0023] Example 2

[0024] Reference Figure 4 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: a fixing groove 68 is provided on the side of the upper tower body 1 near the guide groove 67. A sealing plate 65 is fixedly installed on one side of the fixing groove 68. The fixing groove 68 is formed on the side of the upper tower body 1 near the guide groove 67. The groove structure of the fixing groove 68 can provide a precise installation positioning reference for the sealing plate 65, preventing the sealing plate 65 from shifting during assembly or use. The sealing plate 65, fixedly installed on one side of the fixing groove 68, can seal the gap at the connection between the upper tower body 1 and the guide groove 67 by utilizing its own structural fitting characteristics, preventing external dust, moisture, and other impurities from entering the tower body and affecting equipment operation. It can also prevent the leakage of odorous gases inside the tower body, ensuring the overall sealing of the tower body.

[0025] When in use, align the sealing plate 65 with the mounting side of the fixing groove 68, so that the edge of the sealing plate 65 fits precisely with the groove opening of the fixing groove 68, and the sealing plate 65 can completely cover the gap area on the corresponding side of the fixing groove 68. The third step is to fix and install it. Use the preset fixing methods such as bolt connection or adhesive to firmly install the sealing plate 65 on one side of the fixing groove 68, ensuring that the sealing plate 65 is tightly connected to the fixing groove 68 and the upper tower body 1.

[0026] The remaining structure is the same as that in Example 1.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
