Description

Technical Field

[0001] This utility model relates to the field of pet food production technology, and in particular to a dust purification and dust removal system for pet food production. Background Technology

[0002] In the production of pet food, the screening process is a crucial step in ensuring product quality. By processing materials through a screening machine, different particle sizes can be effectively separated, resulting in pet food pellets that are uniform in size and meet quality standards.

[0003] Currently, the screening process for pet food commonly uses vibrating motors to shake the materials, forcing them through a screen. However, this traditional screening method has significant drawbacks. During vibration, dust particles are easily stirred up, resulting in large amounts of dust not only adhering to equipment surfaces but also entering the workshop environment. This dust not only affects the health of workers, increasing the risk of respiratory diseases, but can also cause electrical equipment malfunctions, posing safety hazards. Furthermore, dust pollution negatively impacts product quality and reduces market competitiveness. Therefore, developing a highly efficient and reliable dust purification and removal system for pet food production is urgently needed, as it is crucial for improving the production environment, ensuring product quality, and enhancing production safety. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a dust purification and removal system for pet food production.

[0005] A dust purification and dust removal system for pet food production designed for this purpose includes a screening box and a material box set on the screening box. The material box has an opening on the upper side and a discharge port at the bottom. A screen is fixedly installed inside the screening box. Dust suction modules are arranged at intervals on the left and right below the discharge port. A feeding channel is formed between the two dust suction modules on the left and right. A feeding component is installed in the feeding channel.

[0006] Preferably, the dust collection module includes a dust collection box that is fixedly connected to the screening box or the material box. The wall of the dust collection box facing the material discharge channel is evenly distributed with dust collection holes. The dust collection box is provided with a connecting pipe for connecting to an external dust collection device.

[0007] Preferably, the screening box is equipped with a connecting pipe, which is connected to the connecting pipe.

[0008] As a preferred option, the connecting pipe is a corrugated pipe.

[0009] Preferably, the dust collection box is equipped with a connecting flange, which is fixedly connected to the material box.

[0010] Preferably, the feeding assembly includes a first feeding shaft disposed in the feeding channel and a first feeding plate arranged in a circumferential array on the first feeding shaft.

[0011] The first feeding shaft is rotatably connected to the material box.

[0012] Preferably, the first feeding plate is a soft rubber plate and is attached to the wall surface of the dust collection box facing the first feeding shaft.

[0013] Preferably, a second material feeding shaft is provided inside the material box above the first material feeding shaft. The second material feeding shaft is rotatably connected to the material box, and multiple second material feeding plates are arranged in a circular array along the second material feeding shaft.

[0014] Preferably, the first feeding shaft and the second feeding shaft are equipped with synchronous pulleys, and the two synchronous pulleys are fitted with synchronous belts.

[0015] Compared with existing technologies, this invention achieves the dual effects of dust removal and stable material conveying through a reasonable structural design. Firstly, the dust-collecting modules spaced at intervals below the discharge port can specifically adsorb dust particles stirred up during material descent. Compared to traditional screening methods, this dust-collecting module can capture dust, significantly reducing dust concentration in the workshop, greatly improving the production environment, effectively protecting the health of workers, reducing dust corrosion of electrical equipment, lowering the risk of equipment failure, and improving production safety. Furthermore, the material-feeding component prevents material from accumulating in the feeding channel due to suction. Attached Figure Description

[0029] See Figures 1-5 A dust purification and removal system for pet food production includes a screening box 10 and a material box 20 mounted on the screening box 10. The material box 20 has an opening on the upper side and a discharge port 210 at the bottom. A screen 30 is fixedly installed inside the screening box 10. Dust suction modules 40 are spaced apart on the left and right sides below the discharge port 210, forming a feeding channel 400 between the two dust suction modules 40. A material feeding component 50 is installed within the feeding channel 400. Through a reasonable structural design, the system achieves the dual effects of dust removal and stable material conveying. First, the dust suction modules spaced apart on the left and right sides below the discharge port can specifically adsorb dust particles raised during material descent. Furthermore, the material feeding component can move the material onto the screen below, thus preventing material accumulation in the feeding channel due to suction.

[0030] See Figure 4 The dust collection module 40 includes a dust collection box 410 fixedly connected to the screening box 10 or the material box 20. The wall surface of the dust collection box 410 facing the discharge channel 400 has evenly distributed dust collection holes 420. The dust collection box 410 is equipped with a connecting pipe 430 for connecting to an external dust collection device. The external dust collection device is an existing industrial dust collection device, which is connected to the connecting pipe 430 via a pipeline. Thus, when the external dust collection device is activated, the negative pressure it generates can drive particulate impurities in the discharge channel 40 into the dust collection box 410 with the airflow, and then output to the external dust collection device via the connecting pipe 430. Furthermore, the aperture of the dust collection holes 420 is set according to the particle size of the material to prevent material from entering the dust collection box.

[0031] See Figure 4 The screening box 10 is equipped with a connecting pipe 110, which is connected to the connecting pipe 430.

[0032] Furthermore, the connecting pipe 430 is a corrugated pipe.

[0033] Furthermore, the dust collection box 410 is provided with a connecting flange 440, which is fixedly connected to the material box 20. Preferably, the connecting flange 440 and the material box 20 can be fixedly connected by rivets.

[0034] See Figure 4 The material feeding assembly 50 includes a first feeding shaft 510 disposed within the feeding channel 400 and first feeding plates 520 arranged in a circumferential array on the first feeding shaft 510; the first feeding shaft 510 is rotatably connected to the material box 20. The first feeding plates 520 rotate with the first feeding shaft 510 to perform circumferential motion. In this embodiment, the first feeding shaft 510 is driven by a motor. The first feeding plates 520 serve to prevent material accumulation and to keep the material within the feeding channel 400. Keeping the material within the feeding channel 400 facilitates airflow to remove dust and impurities.

[0035] See Figure 4 The first feeding plate 520 is a soft rubber plate and is attached to the wall of the dust collection box 410 facing the first feeding shaft 510. The purpose of this design is to prevent the material from being adsorbed onto the wall of the dust collection box 410 due to suction, thus preventing material accumulation.

[0036] See Figure 4 A second material feeding shaft 530 is installed inside the material box 20 above the first feeding shaft 510. The second feeding shaft 530 is rotatably connected to the material box 20. Multiple second feeding plates 540 are arranged in a circular array along the circumference of the second feeding shaft 530. The second feeding shaft 530 drives the second feeding plates 540 to move, thereby driving the material in the material box 20 to be output from the discharge port 210 to the unloading channel 400.

[0037] See Figure 5 The first feeding shaft 510 and the second feeding shaft 530 are equipped with synchronous pulleys 610, and the two synchronous pulleys 610 are fitted with synchronous belts 620.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
