Description

Technical Field

[0001] This utility model belongs to the field of feed production technology, and in particular relates to a self-cleaning device for an additive premixed feed mixer. Background Technology

[0002] In the feed industry production system, additive premix feed mixers are the core equipment for achieving precise proportioning and uniform mixing of various raw materials. Their operating efficiency and cleanliness directly determine the quality and safety of feed products and the continuity of production. As the feed industry develops towards refinement and diversification, the cleaning problems exposed by mixers during long-term use have become increasingly prominent, and have become a key bottleneck restricting the improvement of industry production efficiency and product quality assurance.

[0003] The nozzles of existing feed mixer spray devices are mostly fixed to the top or side wall of the cavity, resulting in limited water coverage and difficulty in penetrating the gaps between the mixing rods. This leads to residual feed on the mixing rods not being washed away, and the residual feed gradually accumulates and deteriorates on the surface of the mixing rods. Especially in the closed, warm environment of the mixer, bacteria and mold can easily grow. When the next batch of feed raw materials enters the mixer, the deteriorated residue will cross-contaminate with the new material, affecting feed production. Therefore, a self-cleaning device for additive premixed feed mixers is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a self-cleaning device for an additive premixed feed mixer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A self-cleaning device for an additive premixed feed mixer includes a mixing tank, an internal stirring assembly connected to the mixing tank, a connecting box connected to the top of the mixing tank, a connecting plate welded to the top of the connecting box, a suction pump connected through the top of the connecting plate, and a connecting hose connected to the top of the suction pump.

[0007] The stirring assembly includes a motor, the output end of which is connected to a worm gear. A turbine is meshed with one side of the worm gear. A connecting shaft is connected through the inner side of the turbine. A gear is connected to the outer side of the connecting shaft. A gear ring is meshed with the outer side of the gear. A stirring rod is connected through the outer side of the connecting shaft. A bidirectional nozzle is connected to one end of the stirring rod. A scraper is connected to the bottom of the gear ring.

[0008] In a further technical solution, there are three gears and three connecting shafts, one end of which is connected through a worm gear, and one end of which is rotatably connected to the inside of the connecting box.

[0009] In a further technical solution, the number of stirring rods is several, and the several stirring rods are arranged alternately. Both the stirring rods and the connecting shaft are hollow. The two water outlets of the bidirectional nozzle are located at one end and the bottom of the stirring rod, respectively.

[0010] In a further technical solution, all three connecting shafts are connected through to the bottom of the connecting disk, and the connecting shafts are rotatably connected to the connecting disk.

[0011] In a further technical solution, a support plate is connected inside the connecting box. The support plate has a ring design. A support rod is connected to the top of the inner side of the connecting box. A limit plate is connected to the bottom end of the support rod. The top and bottom of the toothed ring are rotatably connected to the support plate and the limit plate, respectively.

[0012] In a further technical solution, a feed inlet is connected to one side of the mixing box, and a discharge outlet is connected through the bottom of the mixing box. A discharge valve is connected between the discharge outlet and the mixing box. The scraper has a U-shaped design, and its two sides and bottom are movably connected to the inner wall and bottom of the mixing box, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, both the connecting shaft and the stirring rod of the stirring component are hollow, and the end of the stirring rod is connected to a bidirectional nozzle. The two outlets of the bidirectional nozzle are located at one end and the bottom of the stirring rod, respectively. When the motor drives the connecting shaft to rotate, the bidirectional nozzle rotates synchronously with the stirring rod, and the water flow can form a 360° dynamic spray range along the stirring trajectory. Compared with the traditional nozzles fixed to the top or side wall, this design can directly penetrate the gap between the stirring rods and accurately rinse the surface of the stirring rod, the outside of the connecting shaft, and other areas prone to residue, avoiding the accumulation and deterioration of feed on the surface of the stirring components, and completely solving the problem of incomplete cleaning caused by the "blind spot of spraying".

[0015] In this invention, a U-shaped scraper connected to the bottom of the gear ring moves in close contact with the inner wall and bottom of the mixing chamber. Under the meshing transmission of the gear and the gear ring, the scraper rotates synchronously with the gear ring. During rotation, the scraper can physically scrape off residual feed on the side walls and bottom of the mixing chamber. Combined with the water flow from the bidirectional spray nozzles, a dual cleaning mechanism of scraping and spraying is formed, effectively removing stubborn residues from the inner wall of the chamber and ensuring that there are no dead corners with feed residue inside the mixer.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] like Figures 1-4 As shown, this utility model embodiment provides a self-cleaning device for an additive premixed feed mixer, including a mixing box 1, a stirring assembly 2 connected inside the mixing box 1, a connecting box 3 connected to the top of the mixing box 1, a connecting plate 4 welded to the top of the connecting box 3, a suction pump 5 connected through the top of the connecting plate 4, and a connecting hose 6 connected to the top of the suction pump 5.

[0025] The stirring assembly 2 includes a motor 201, the output end of which is connected to a worm gear 202. A turbine 203 is meshed with one side of the worm gear 202. A connecting shaft 204 is connected through the inner side of the turbine 203. A gear 205 is connected to the outer side of the connecting shaft 204. A gear ring 206 is meshed with the outer side of the gear 205. A stirring rod 207 is connected through the outer side of the connecting shaft 204. A bidirectional nozzle 208 is connected to one end of the stirring rod 207. A scraper 209 is connected to the bottom of the gear ring 206.

[0026] In this embodiment, the motor 201 is started, and its output end drives the worm gear 202 to rotate. The worm gear meshes with the turbine 203, which drives the connected shaft 204 to rotate. Since all three connected shafts 204 mesh with the gear ring 206 through the gear 205, when one of the connected shafts 204 is driven to rotate, the other two connected shafts 204 rotate synchronously through the linkage of the gear ring 206. The suction pump 5 draws clean water through the connecting hose 6, pressurizes it, and delivers it to the inside of the connecting plate 4. Since the connected shaft 204 and the stirring rod 207 are both hollow and the three are connected through the internal channel of the connecting plate 4, the high-pressure water flows into the stirring rod 207 along the inner cavity of the connected shaft 204 and finally sprays out from the bidirectional nozzle 208. The gear ring 206 rotates stably under the bidirectional limitation of the support plate 11 and the limiting plate 10, which drives the U-shaped scraper 209 at the bottom to make a circular motion along the inner wall and bottom of the mixing box 1, so as to physically scrape off the residual feed on the inner wall of the cavity.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, specifically, there are three gears 205 and three connecting shafts 204. One end of the connecting shaft 204 is connected through to the turbine 203, and one end of the worm gear 202 is connected to the inside of the connecting box 3 for rotation.

[0028] There are several stirring rods 207, which are arranged in an alternating manner. Both the stirring rods 207 and the connecting shaft 204 are hollow. The two water outlets of the bidirectional nozzle 208 are located at one end and the bottom of the stirring rod 207, respectively.

[0029] All three connecting shafts 204 are connected through to the bottom of the connecting plate 4, and the connecting shafts 204 are rotatably connected to the connecting plate 4;

[0030] The connecting box 3 is internally connected to a support plate 11, which is a ring design. The top of the inner side of the connecting box 3 is connected to a support rod 12, and the bottom end of the support rod 12 is connected to a limit plate 10. The top and bottom of the toothed ring 206 are rotatably connected to the support plate 11 and the limit plate 10, respectively.

[0031] A feed inlet 7 is connected to one side of the mixing box 1, and a discharge outlet 9 is connected through the bottom of the mixing box 1. A discharge valve 8 is connected between the discharge outlet 9 and the mixing box 1. The scraper 209 has a U-shaped design, and its two sides and bottom are movably connected to the inner wall and bottom of the mixing box 1, respectively.

[0032] In this embodiment, after cleaning is completed, the discharge valve 8 is opened, and the cleaning wastewater at the bottom of the mixing tank 1, carrying residual impurities, is discharged through the discharge port 9, completing one cleaning cycle. The toothed ring 207 can be limited by the set support rod 12 and the limiting plate 10. The end of the stirring rod 207 is connected to the bidirectional nozzle 208. The two water outlets of the bidirectional nozzle 208 are located at one end and the bottom of the stirring rod 207, respectively. When the motor 201 drives the connecting shaft to rotate, the bidirectional nozzle 208 rotates synchronously with the stirring rod 207. The water flow can form a 360° dynamic spray range along the stirring trajectory. Compared with the traditional nozzles fixed to the top or side wall, this design can directly penetrate the gap between the stirring rods 207 and accurately rinse the surface of the stirring rod 207, the outside of the connecting shaft 204, and other areas prone to residue.

[0033] The working principle of this utility model is as follows: First, the motor 201 is started, and its output end drives the worm gear 202 to rotate. The worm gear meshes with the turbine 203, driving the connected shaft 204 to rotate. Since all three connected shafts 204 mesh with the gear ring 206 through the gear 205, when one connected shaft 204 is driven to rotate, the other two connected shafts 204 rotate synchronously. Then, the suction pump 5 draws clean water through the connecting hose 6, pressurizes it, and delivers it to the inside of the connecting plate 4. The high-pressure water flows along the inner cavity of the connected shaft 204 into the stirring rod 207, and finally sprays out from the bidirectional nozzle 208. The gear ring 206 is positioned on the support plate 11 and the limiting device. The plate 10 rotates stably under bidirectional limiting, driving the U-shaped scraper 209 at the bottom to make a circular motion along the inner wall and bottom of the mixing box 1, realizing the physical scraping of residual feed on the inner wall of the cavity. Finally, the two outlets of the bidirectional nozzle 208 are located at one end and the bottom of the stirring rod 207, respectively. When the motor 201 drives the connecting shaft to rotate, the bidirectional nozzle 208 rotates synchronously with the stirring rod 207, and the water flow can form a 360° dynamic spray range along the stirring trajectory. Compared with the traditional nozzles fixed to the top or side wall, this design can directly penetrate the gap between the stirring rods 207 and accurately rinse the surface of the stirring rod 207, the outside of the connecting shaft 204 and other areas prone to residue.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
