Description

Technical Field

[0001] This utility model relates to the field of pollutant treatment technology, specifically to a treatment machine for odorous pollutants from pig manure. Background Technology

[0002] In today's agricultural sector, pig farming is expanding to meet the growing market demand for pork and related products. However, pig manure, a large amount of waste generated during the farming process, can cause serious environmental problems if not properly treated. Pig manure contains large amounts of organic matter, nitrogen, phosphorus, and other nutrients, but also emits a pungent odor. These foul substances not only significantly impact air quality around farms, harming the health of farmers and nearby residents, but also pollute soil and water sources, disrupting the ecological balance. Therefore, effectively treating pig manure to achieve its reduction, harmlessness, and resource utilization has become a critical issue that the livestock industry urgently needs to address.

[0003] Most pig manure treatment devices widely used in the market today have relatively limited functions, mainly focusing on the crushing stage. These devices use mechanical blades or grinding components to break large pieces of pig manure into smaller particles to increase the specific surface area of ​​the manure, facilitating subsequent processing and utilization. However, they only complete the crushing step and cannot effectively dehydrate the crushed pig manure. Pig manure contains a large amount of free water and bound water. The high moisture content not only increases the volume and weight of the pig manure, causing great difficulties in transportation and storage, but also provides favorable conditions for the generation and proliferation of malodorous substances. Due to the lack of dehydration function, the pig manure treated by existing devices still retains a high moisture content, which cannot meet the moisture content requirements of subsequent composting, fermentation and other resource utilization processes, and is also difficult to apply directly as organic fertilizer to farmland, thus limiting the resource utilization efficiency of pig manure. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a treatment machine for odorous pollutants from pig manure, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A machine for treating odorous pollutants from pig manure includes:

[0007] Organism;

[0008] The frame is located inside the machine body;

[0009] The feed hopper is mounted on the top of the frame and contains crushing rollers driven by a power source.

[0010] The extrusion tube is inclinedly mounted on the frame and located below the feed hopper. Inside it is an extrusion auger and an extrusion motor that is connected to the extrusion auger.

[0011] The discharge port is located at the bottom of the discharge end of the extrusion tube;

[0012] The drain pipe is located at the bottom of the extrusion tube near the extrusion motor end;

[0013] An openable and closable sealing plate is slidably installed at the bottom of the discharge port;

[0014] When the sealing plate is closed, the extrusion auger squeezes the crushed material toward the discharge end to dehydrate it, and the liquid is discharged through the drain pipe; when the sealing plate is open, the dehydrated material is discharged through the feed port.

[0015] Based on the above technical solution, the present invention can be further improved as follows.

[0016] Furthermore, a crushing motor is provided on one side of the feed hopper, and the crushing motor is connected to the crushing roller drive. The two crushing rollers achieve reverse transmission through gear meshing.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] This design significantly improves the crushing effect of pig manure. The crushing motor powers the crushing rollers, causing them to rotate at high speed. The two crushing rollers are driven in opposite directions by gear meshing. This reverse rotation increases the shearing and compressing force on the pig manure. Large pieces of pig manure, after entering the feed hopper, are subjected to strong forces from different directions by the two crushing rollers, which quickly and uniformly crush them into smaller particles. Smaller particles not only facilitate subsequent extrusion and dehydration in the extrusion tube, allowing for more complete removal of moisture, but also increase the contact area between the material and the processing equipment, improving overall processing efficiency, reducing problems such as poor processing or equipment blockage caused by excessively large materials, and extending the service life of the equipment.

[0019] Furthermore, the extrusion tube includes a sleeve and an inner tube coaxially sleeved together, and the extrusion auger is rotatably installed inside the inner tube;

[0020] The inner tube has a through hole at the position corresponding to the drain pipe.

[0021] The beneficial effects of adopting the above-mentioned further solutions are:

[0022] This structure significantly optimizes the dehydration process. The extrusion auger, installed inside the inner tube, effectively compresses and conveys the crushed pig manure. As the auger rotates, it pushes the material towards the discharge end. During this process, the material is subjected to continuous pressure, squeezing out the water. The inner tube has through-holes corresponding to the drain pipe, allowing the squeezed-out water to flow smoothly into the drain pipe and exit the equipment. This design makes solid-liquid separation more efficient, rapidly reducing the moisture content of the pig manure and minimizing the generation of odorous gases, as many odorous substances are dissolved in water. Simultaneously, the coaxial sleeve structure of the outer and inner tubes provides protection and support, ensuring the stable operation of the extrusion auger and improving the reliability and durability of the equipment.

[0023] Furthermore, support frames are provided on both sides of the discharge port, and slide rails with grooves are installed on the support frames;

[0024] The sealing plate is slidably connected to the slide rail via a groove, and a handle is provided on the sealing plate.

[0025] The beneficial effects of adopting the above-mentioned further solutions are:

[0026] This design greatly facilitates material discharge. Support frames with grooved rails are installed on both sides of the discharge port, allowing the sealing plate to slide stably against the rails. Operators can easily control the opening and closing of the sealing plate using a handle on the plate. When dehydrated material needs to be discharged, pulling the handle opens the sealing plate, allowing the material to flow smoothly through the discharge port; when discharge is not needed, pushing the handle closes the sealing plate to prevent leakage. This simple and quick operation greatly reduces the difficulty and labor intensity of manual operation, improves the efficiency of the entire processing flow, and ensures the equipment's sealing during operation, preventing material spillage and the release of foul odors.

[0027] Furthermore, the inclination angle of the extrusion tube makes its discharge end height lower than its feed end height.

[0028] The beneficial effects of adopting the above-mentioned further solutions are:

[0029] The inclined design of the extrusion tube fully utilizes the force of gravity on the material. As the extrusion auger propels the material towards the discharge end, the lower height of the discharge end allows it to slide more smoothly towards the discharge end with the aid of gravity. This design reduces the possibility of material accumulation and blockage within the extrusion tube, ensuring continuous and stable dewatering. Even under high-load operation, it ensures normal equipment operation, improves processing capacity and efficiency, and reduces equipment failure rate and maintenance costs.

[0030] Furthermore, the sealing plate is connected to a drive mechanism, which includes an electric push rod or a cylinder, for automatically controlling the opening and closing movement of the sealing plate along the slide rail to realize remote operation of the discharge port.

[0031] The beneficial effects of adopting the above-mentioned further solutions are:

[0032] Significantly improving the automation level and ease of operation of the equipment, the opening and closing of the sealing plate is precisely controlled by electric or pneumatic drive. This not only avoids the tediousness of frequent manual operation and the potential risk of odor exposure, but also ensures that the discharge port is tightly sealed, thereby optimizing dehydration efficiency and reducing odor leakage. At the same time, this design facilitates the integration of intelligent control systems to achieve remote operation or programmed discharge, enhancing the stability and durability of equipment operation, and is especially suitable for the continuous operation needs of large-scale pig manure treatment.

[0033] Furthermore, the discharge end of the extrusion tube is connected to a negative pressure deodorization pipe, which draws the malodorous gas generated during the dehydration process to an external treatment device.

[0034] The beneficial effects of adopting the above-mentioned further solutions are:

[0035] By installing a negative pressure suction device directly at the material discharge outlet, high-concentration odorous gases released during the dehydration process can be actively captured, effectively preventing the spread of odors and environmental pollution. Simultaneously, the odorous gases are directed to an external treatment unit for centralized treatment, significantly improving the equipment's environmental performance. This design specifically addresses the most serious problem of odor escape at the discharge end during pig manure treatment, forming a complete odor-proof closed-loop system with the feed hopper sealing cover. This not only meets environmental protection requirements but also improves the working environment for operators.

[0036] This invention provides a machine for treating odorous pollutants from pig manure. It has the following beneficial effects:

[0037] An extrusion auger is installed inside the extrusion tube. When the sealing plate is closed, the extrusion auger squeezes the crushed material towards the discharge end. During this process, the material is subjected to continuous and uniform pressure, allowing the liquid to be fully squeezed out. Simultaneously, a through-hole is provided in the inner tube at the corresponding location of the drain pipe, allowing the squeezed liquid to be smoothly discharged through the drain pipe. This achieves efficient solid-liquid separation, effectively reducing the moisture content in pig manure and minimizing the sources of odorous gases, as many odorous substances are dissolved in water; dehydration significantly reduces the odor.

[0038] The bottom of the discharge port is equipped with an openable and closable sealing plate. The sealing plate is slidably installed at the bottom of the discharge port and is slidably connected through the cooperation of a slide rail and a slide groove. The sealing plate is also equipped with a handle. This design allows the operator to easily control the opening and closing of the sealing plate. When it is necessary to discharge the dehydrated material, simply slide the sealing plate open with the handle, and the material can be discharged smoothly through the discharge port. The operation is simple and quick, improving the efficiency of the entire processing flow and reducing the difficulty and labor intensity of manual operation. Attached Figure Description

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0049] Example 1

[0050] A machine for treating odorous pollutants from pig manure includes:

[0051] Body 1;

[0052] Frame 4 is located inside the body 1;

[0053] The feed hopper 2, mounted on top of the frame 4, houses a crushing roller 202 driven by a power source. A crushing motor 201 is located on one side of the feed hopper 2, and the motor is connected to the crushing roller 202. The two crushing rollers 202 are driven in opposite directions via gear meshing. This design significantly improves the crushing effect of pig manure. The crushing motor 201 provides power to the crushing rollers 202, causing them to rotate at high speed. The reverse rotation mode increases the shearing and compressing force on the pig manure. Large pieces of pig manure, upon entering the feed hopper 2, are subjected to strong forces from different directions by the two crushing rollers 202, resulting in rapid and uniform crushing into smaller particles. These smaller particles not only facilitate subsequent extrusion and dehydration in the extrusion tube 3, allowing for more complete extraction of moisture, but also increase the contact area between the material and the processing equipment, improving overall processing efficiency, reducing problems such as poor processing or equipment blockage caused by excessively large materials, and extending the service life of the equipment.

[0054] The extrusion tube 3 is inclinedly mounted on the frame 4 and located below the feed hopper 2. Inside it is an extrusion auger 306 and an extrusion motor 302 that is connected to the extrusion auger 306. The discharge end of the extrusion tube 3 is connected to a negative pressure deodorization pipe, which draws the odorous gas generated during the dehydration process to an external treatment device.

[0055] The discharge port 301 is located at the bottom of the discharge end of the extrusion tube 3;

[0056] The drain pipe 307 is located at the bottom of the extrusion pipe 3 near the end of the extrusion motor 302;

[0057] An openable and closable sealing plate 304 is slidably installed at the bottom of the discharge port 301. The sealing plate 304 is connected to a drive mechanism, which includes an electric push rod or a cylinder, for automatically controlling the opening and closing movement of the sealing plate 304 along the slide rail 309 to realize remote operation of the discharge port 301.

[0058] When the sealing plate 304 is closed, the extrusion auger 306 squeezes the crushed material toward the discharge end to dehydrate it, and the liquid is discharged through the drain pipe 307; when the sealing plate 304 is open, the dehydrated material is discharged through the discharge port 301.

[0059] Example 2

[0060] To further improve the performance of the pig manure odor pollutant treatment machine and optimize its working effect in key aspects such as dehydration and discharge, for example, such as Figures 1 to 4 As shown, this utility model also includes:

[0061] The extrusion tube 3 includes a sleeve 303 and an inner tube 305 coaxially sleeved together, and the extrusion auger 306 is rotatably installed inside the inner tube 305;

[0062] The inner tube 305 has through holes at the corresponding positions of the drain pipe 307, a structure that greatly optimizes the dewatering process. The extrusion auger 306 is installed inside the inner tube 305, effectively squeezing and conveying the crushed pig manure. When the extrusion auger 306 rotates, it pushes the material towards the discharge end. During this process, the material is subjected to continuous pressure, squeezing out the water. The through holes in the inner tube 305 at the corresponding positions of the drain pipe 307 allow the squeezed-out water to flow smoothly into the drain pipe 307 and be discharged outside the equipment. This design makes solid-liquid separation more efficient, rapidly reducing the moisture content in the pig manure and decreasing the generation of odorous gases, as many odorous substances are dissolved in water. Simultaneously, the coaxial sleeve structure of the sleeve 303 and the inner tube 305 also provides protection and support, ensuring the stable operation of the extrusion auger 306 and improving the reliability and durability of the equipment.

[0063] Support frames 308 are provided on both sides of the discharge port 301, and slide rails 309 with sliding grooves 311 are installed on the support frames 308.

[0064] The sealing plate 304 is slidably connected to the slide rail 309 via a groove 311, and a handle 310 is provided on the sealing plate 304. This design greatly facilitates the discharge of materials. Support frames 308 are installed on both sides of the discharge port 301, and slide rails 309 with grooves 311 are mounted on them, allowing the sealing plate 304 to achieve a stable sliding connection with the slide rails 309 via the grooves 311. Operators can easily control the opening and closing of the sealing plate 304 using the handle 310. When dehydrated material needs to be discharged, pulling the handle 310 opens the sealing plate 304, allowing the material to be discharged smoothly through the discharge port 301; when discharge is not needed, pushing the handle 310 closes the sealing plate 304 to prevent material leakage. This simple and quick operation greatly reduces the difficulty and labor intensity of manual operation, improves the efficiency of the entire processing flow, and also ensures the sealing of the equipment during operation, preventing material spillage and the leakage of foul odors.

[0065] The inclined angle of the extrusion tube 3 ensures that the height of its discharge end is lower than that of its feed end, and this inclined design fully utilizes the gravity of the material. As the extrusion auger 306 pushes the material towards the discharge end, the lower height of the discharge end allows the material to slide more smoothly towards the discharge end with the aid of gravity. This design reduces the possibility of material accumulation and blockage within the extrusion tube 3, ensuring continuous and stable dewatering. Even under high-load operation, it ensures normal equipment operation, improves processing capacity and efficiency, and reduces equipment failure rate and maintenance costs.

[0066] Working principle:

[0067] Pollutants are fed into the feed hopper 2. Inside the feed hopper 2, the crushing rollers 202, driven by a power source, are driven by the crushing motor 201. Through the meshing of the gears of the two crushing rollers 202, reverse transmission is achieved, and the fed pollutants are crushed.

[0068] The crushed contaminants fall into the extrusion pipe 3, which is inclined and installed below the feed hopper 2. The extrusion auger 306 inside the extrusion pipe 3 rotates under the drive of the extrusion motor 302. At this time, if the sealing plate 304 at the bottom of the discharge port 301 is in a closed state, the extrusion auger 306 will squeeze the crushed contaminant material towards the discharge end. Under the action of squeezing, the liquid in the material flows to the bottom end and is discharged through the through hole on the inner pipe 305 corresponding to the position of the drain pipe 307, thereby achieving the dehydration treatment of the material.

[0069] After dehydration is complete, the sealing plate 304 is slid on the slide groove 311 of the slide rail 309 by the handle 310 on the sealing plate 304, opening the sealing plate 304 and discharging the dehydrated material through the discharge port 301. The extrusion tube 3 is inclined and the height of the discharge end is lower than the height of the feed end. This design helps the material to move smoothly to the discharge end and be discharged under the action of gravity and the extrusion auger 306.

[0070] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
