Description

Technical Field

[0001] This utility model relates to the field of livestock feed production technology, specifically to a settling chamber for livestock feed pellet production. Background Technology

[0002] Animal feed refers to live feed such as various insects, fish, and shrimp, as well as eggs, meat, fishmeal, silkworm pupa powder, fly larvae powder, and milk powder. During the production of animal feed, a significant amount of dust is generated as the feed slides out of the processing equipment's outlet, thus requiring dust removal devices.

[0003] A search revealed that patent CN221045724U discloses a dust removal device for animal feed production. While this device uses a water pump mounted on the bottom inner wall of the spray box, with a conduit connected to the pump's outlet and a serpentine pipe, allowing water from the spray box to be injected into the serpentine pipe and sprayed into the spray box via multiple nozzles, the device suffers from a significant drawback. When dust settles and accumulates around the pump or its inlet, it severely obstructs water flow, significantly reducing the pump's pumping efficiency and impacting the overall operation of the spray system. Long-term dust accumulation can also cause wear or jamming of internal pump components, shortening the pump's lifespan or even causing damage, increasing maintenance costs and downtime. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a settling chamber for livestock feed pellet production, 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 settling chamber for livestock feed pellet production includes a tank body, with a power module installed at the bottom of the tank body.

[0007] A fixing frame is installed inside the tank. A first bearing seat and a second bearing seat are installed inside the tank via the fixing frame. A drive shaft is inserted into the second bearing seat and the first bearing seat. An auger is provided on the outside of the drive shaft. A magnetic coupler is provided at the bottom end of the drive shaft. An end cover is installed at the bottom end of the tank. A magnetic coupler is also installed on the power module. The power module drives the drive shaft to rotate through the end cover via the magnetic coupler.

[0008] An inlet / outlet pipe is installed on one side of the tank, and a pressure regulating pipe is installed at the top of the tank. The tank is filled with pure water. When the pressure regulating pipe is connected to the suction end of the vacuum pump, the inlet / outlet pipe draws the raised dust into the tank for collection through the negative pressure inside the tank, and passes the dust into the pure water inside the tank. When the pressure regulating pipe is connected to the outlet end of the vacuum pump, the high pressure inside the tank discharges the pure water mixed with settled dust from the tank through the inlet / outlet pipe.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the drive shaft is provided with a spline, and the drive shaft is connected to the first bearing seat and the second bearing seat through the spline for limiting insertion.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] A spline connection achieves a tight connection between the drive shaft and the bearing housing by interlocking the threads on the shaft with the grooves on the bushing (in this case, the bearing housing). This connection method is not only compact but also effectively prevents the drive shaft from loosening or shifting under high-speed rotation or high torque, ensuring the stability of the transmission system. Although a certain degree of precision and skill is required during installation, once installed correctly, the spline connection is relatively simple and stable. It also provides a relatively convenient way to disassemble or replace the drive shaft or bearing housing, reducing maintenance costs and time.

[0013] Furthermore, the outer side of the end cap is threaded, and the end cap is threaded to the tank body. The bottom end of the end cap is provided with a support block, and a through hole is provided on the support block. A pry bar is inserted into the through hole. The end cap is rotated by the pry bar to install and remove the end cap.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The threaded connection design ensures a secure and reliable connection between the end cap and the tank body, while also facilitating installation and disassembly. Connecting or separating the end cap from the tank body can be achieved simply by rotating it, without the need for additional tools or complex procedures. The support block and through-hole design further simplify the disassembly process. When it is necessary to remove the end cap, simply insert a pry bar into the through-hole and rotate the pry bar to easily rotate the end cap, avoiding the difficulties or injuries that may occur when rotating it by hand. The easy-to-disassemble structure makes cleaning, maintenance, and repair of the equipment's interior much more convenient. When it is necessary to clean the inside of the tank or replace parts, the end cap can be quickly removed, reducing downtime and improving production efficiency.

[0016] Furthermore, the magnetic coupler is provided with a fixed disk, on which magnets are embedded, and the magnetic poles of two adjacent magnets are arranged in opposite directions.

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

[0018] When the magnetic poles of two adjacent magnets point in opposite directions, they generate a stronger magnetic field in the adjacent region. This enhanced magnetic field helps improve the transmission efficiency and torque transfer capability of the magnetic coupler. The increased magnetic field strength results in denser magnetic field lines, thus enhancing the power transmission performance of the magnetic coupler. The arrangement of adjacent magnetic poles pointing in opposite directions helps reduce magnetic leakage outside the coupler. The magnetic field lines form a closed loop between adjacent magnets, reducing outward radiated magnetic fields, which helps reduce electromagnetic interference to the surrounding environment and improves the overall performance of the device.

[0019] Furthermore, the power module is provided with a base, and a motor is provided inside the base. The magnetic coupler of the power module is installed at the output end of the motor inside the base.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] Magnetic couplers transmit torque via a magnetic field, achieving contactless transmission between the motor and the load. This non-contact design avoids friction and wear inherent in traditional mechanical transmissions, thus extending equipment lifespan and reducing the frequency of maintenance and component replacement. During power transmission, the absence of mechanical contact reduces energy loss and improves transmission efficiency. Furthermore, by adjusting the air gap of the magnetic coupler, precise control of the load speed can be achieved, further enhancing the system's energy efficiency.

[0022] Furthermore, the inlet and outlet pipes are located at one end inside the tank, near the end cap.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] When the inlet / outlet pipe is located near the end cap at one end of the tank, the flow path of the material within the tank is shortened, reducing the time the material spends and mixes inside, thereby improving the efficiency of the feeding and discharging operations. This design can significantly accelerate production, especially in scenarios requiring frequent feeding and discharging. This design also allows for more efficient use of the tank's internal space. Positioning the inlet / outlet pipe near the end cap reduces the space occupied in the central area of ​​the tank, providing more installation space for other components or structures (such as augers). It also facilitates cleaning and maintenance of the tank's interior.

[0025] Furthermore, the bottom of the tank is conical and coaxial with the end cap. The diameter of the end cap is smaller than the diameter of the drive shaft, which facilitates the removal of the auger from the tank.

[0026] The beneficial effects of adopting the above-mentioned further solutions are:

[0027] The conical design allows material at the bottom of the tank to naturally converge towards the center, forming a centralized discharge point. This design significantly improves material discharge efficiency and reduces material residue at the bottom of the tank, thereby enhancing the cleanliness and efficiency of the production process. The conical bottom design also makes the tank interior easier to clean. During cleaning, water or cleaning fluid can more easily reach every corner of the tank, reducing cleaning dead zones. Furthermore, when maintenance or replacement of internal components, such as the auger, is required, the conical bottom design provides greater operating space, facilitating maintenance personnel.

[0028] This invention provides a settling chamber for livestock feed pellet production. It has the following beneficial effects:

[0029] By sucking in air bubbles carrying dust and dispersing them in pure water within a tank, the dust particles quickly settle due to the wetting effect of the water and gravity, thus achieving a highly efficient dust removal effect. This method is more effective than traditional dry dust removal and reduces dust pollution to the environment.

[0030] The power module is connected to the tank via a magnetic coupler, eliminating the need for direct mechanical connection and facilitating installation and maintenance. The magnetic coupler avoids direct contact between the motor and drive shaft, reducing safety hazards caused by mechanical failures and also lowering noise and vibration. The tapered design at the bottom of the tank and the threaded connection of the end caps make it easy and quick to remove components such as the auger, facilitating cleaning and maintenance of the tank's interior. Through-hole designs on the support blocks allow for easy rotation of the end caps using a pry bar, further simplifying the disassembly process.

[0031] By adjusting the connection between the pressure regulating pipe and the vacuum pump (either the suction end or the discharge end), the pressure inside the tank can be flexibly controlled, enabling both dust suction and drainage functions. It can be used to suck in gases containing dust or to discharge treated pure water containing settled dust, improving the equipment's utilization rate and flexibility. Attached Figure Description

[0040] 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.

[0041] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0042] Example 1

[0043] A settling chamber for livestock feed pellet production includes a tank body 3. A power module 4 is installed at the bottom of the tank body 3. The power module 4 has a base 403, and a motor is installed inside the base 403. A magnetic coupler 307 of the power module 4 is installed at the output end of the motor inside the base 403. The magnetic coupler 307 transmits torque through a magnetic field, realizing contactless transmission between the motor and the load. This non-contact design avoids friction and wear in traditional mechanical transmission, thereby extending the service life of the equipment and reducing the frequency of maintenance and parts replacement. During power transmission, the magnetic coupler 307 reduces energy loss and improves transmission efficiency due to the absence of mechanical contact. Meanwhile, by adjusting the air gap size of the magnetic coupler 307, precise control of the load speed can be achieved, further improving the system's energy efficiency. A mounting bracket 301 is installed inside the tank 3, and a first bearing seat 302 and a second bearing seat 303 are mounted inside the tank 3 via the mounting bracket 301. A drive shaft 306 is inserted into the second bearing seat 303 and the first bearing seat 302. The drive shaft 306 is equipped with a spline 304, which limits its insertion into the first bearing seat 302 and the second bearing seat 303. The spline 304 connection achieves a tight connection between the drive shaft 306 and the bearing seat by the interlocking of the threads on the shaft and the grooves on the bushing (here referring to the bearing seat). This connection method is not only compact but also effectively prevents the drive shaft 306 from loosening or shifting when rotating at high speeds or bearing large torques, thus ensuring the stability of the transmission system. Although the spline 304 connection requires a certain degree of precision and skill during installation, once installed correctly, its structure is relatively simple and stable. When it is necessary to disassemble or replace the drive shaft 306 or bearing housing, the spline 304 connection provides a relatively convenient operation method, reducing maintenance costs and time. An auger 305 is provided on the outside of the drive shaft 306. The auger 305 disperses the air bubbles containing dust drawn into the tank 3 into the pure water within the tank 3. A magnetic coupler 307 is provided at the bottom end of the drive shaft 306. An end cover 5 is installed at the bottom end of the tank 3. The bottom end of the tank 3 is conical and coaxial with the end cover 5. The diameter of the end cover 5 is smaller than the diameter of the drive shaft 306, facilitating the removal of the auger 305 from the tank 3. The conical design allows the material at the bottom of the tank 3 to naturally converge towards the center, forming a concentrated discharge point. This design greatly improves the material discharge efficiency and reduces material residue at the bottom of the tank 3, thereby improving the cleanliness and efficiency of the production process. The conical bottom design also makes the interior of the tank 3 easier to clean. During the cleaning process, the water flow or cleaning fluid can more easily reach every corner of the tank 3, reducing cleaning dead spots.Meanwhile, when internal components such as the auger 305 need maintenance or replacement, the conical bottom design provides greater operating space, facilitating maintenance personnel. The end cap 5 has threads 501 on its outer side, connecting it to the tank body 3. A support block 502 is located at the bottom of the end cap 5, with a through hole 503. A pry bar is inserted into the through hole 503, allowing the end cap 5 to be rotated for installation and removal. The threaded connection 501 ensures a secure and reliable connection between the end cap 5 and the tank body 3, while also facilitating installation and removal. Connection or separation from the tank body 3 can be achieved simply by rotating the end cap 5, without the need for additional tools or complex procedures. The design of the support block 502 and the through hole 503 further simplifies the disassembly process. When removing the end cap 5, simply insert the pry bar into the through hole 503 and rotate it to easily rotate the end cap 5, avoiding the difficulties or injuries that might occur with manual rotation. This easily disassembled structure makes cleaning, maintenance, and repair of the equipment's interior much more convenient. When cleaning or replacing parts inside the tank 3 is required, the end cover 5 can be quickly removed, reducing downtime and improving production efficiency. A magnetic coupler 307 is also installed on the power module 4. The power module 4 drives the drive shaft 306 to rotate via the end cover 5 through the magnetic coupler 307. The magnetic coupler 307 has a fixed disk 402, on which magnets 401 are embedded. The magnetic poles of adjacent magnets 401 are arranged in opposite directions. When the magnetic poles of adjacent magnets 401 are in opposite directions, they generate an enhanced magnetic field in the adjacent area. This enhanced magnetic field helps improve the transmission efficiency and torque transmission capability of the magnetic coupler 307. Due to the increased magnetic field strength, the magnetic lines of force become denser, thereby enhancing the effectiveness of the magnetic coupler 307 in transmitting power. The arrangement of adjacent magnetic poles in opposite directions helps reduce magnetic leakage outside the coupler. The magnetic field lines form a closed loop between adjacent magnets 401, reducing the outward radiated magnetic field. This helps to reduce electromagnetic interference to the surrounding environment and improve the overall performance of the equipment.

[0044] Example 2

[0045] To facilitate dust collection and discharge from tank 3, for example, as shown... Figures 1 to 4As shown, the present invention also includes: an inlet / outlet pipe 1 installed on one side of the tank body 3, with one end of the inlet / outlet pipe 1 inside the tank body 3 close to the end cover 5. When the inlet / outlet pipe 1 is located inside the tank body 3 close to the end cover 5, the flow path of the material within the tank body 3 can be shortened, reducing the time the material stays and mixes inside the tank, thereby improving the efficiency of the inlet / outlet operation. Especially in scenarios requiring frequent inlet / outlet operations, this design can significantly accelerate the production pace. This design allows for more rational use of the space inside the tank body 3. The inlet / outlet pipe 1 being close to the end cover 5 reduces the occupation of the central area inside the tank body 3, providing more installation space for other components or structures (such as the auger 305). At the same time, it is also convenient to clean and maintain the inside of the tank 3. The top of the tank 3 is equipped with a pressure regulating pipe 2. The tank 3 is filled with pure water. When the pressure regulating pipe 2 is connected to the suction end of the vacuum pump, the inlet and outlet pipe 1 draws the dust raised into the tank 3 for collection through the negative pressure inside the tank 3, and passes the dust into the pure water inside the tank 3. When the pressure regulating pipe 2 is connected to the outlet end of the vacuum pump, the high pressure inside the tank 3 discharges the pure water mixed with settled dust through the inlet and outlet pipe 1.

[0046] Working principle:

[0047] During the feed pellet production process, the generated dust is sucked into the settling chamber tank 3 through the inlet / outlet pipe 1. The tank 3 is filled with pure water. When the dust enters the tank 3, it comes into contact with the pure water and is wetted. The auger 305 inside the tank 3 rotates under the drive of the power module 4. Its blades break up the air bubbles containing dust that are sucked in, allowing the dust particles to come into more thorough contact with the water and settle.

[0048] After being dispersed, the dust particles gradually settle to the bottom of tank 3 under the influence of gravity in pure water. The conical design at the bottom of tank 3 helps to facilitate the aggregation and discharge of the settled particles.

[0049] The pressure regulating pipe 2 is connected to the vacuum pump. By adjusting the connection method (suction end or outlet end), the pressure inside the tank 3 can be controlled. When the pressure regulating pipe 2 is connected to the suction end of the vacuum pump, a negative pressure is formed inside the tank 3, and external dust is drawn into the tank 3 for collection through the inlet / outlet pipe 1. When the pressure regulating pipe 2 is connected to the outlet end of the vacuum pump, a positive pressure is formed inside the tank 3, and pure water containing settled dust is discharged from the tank 3 through the inlet / outlet pipe 1 for further treatment or discharge.

[0050] The power module 4 drives the drive shaft 306 to rotate via a magnetic coupler 307. The magnetic coupler 307 enables non-contact transmission between the power module 4 and the tank 3, reducing mechanical failures and noise. The spline 304 design on the drive shaft 306 ensures the stability and limit engagement of the auger 305 during rotation. The tank 3 and the end cover 5 are connected by a thread 501 and can be disassembled with the aid of a pry bar for easy maintenance and cleaning.
