Description

Technical Field

[0001] This utility model relates to the technical field of vegetable drying equipment, specifically a dust collection device. Background Technology

[0002] The dehydrated vegetables in instant noodle seasoning packets are made by removing water from fresh vegetables while retaining their nutrients and flavor. The production process must balance efficiency, taste, and shelf life. After raw material selection, washing and peeling, cutting and shaping, and dehydration, the vegetables are screened by a vibrating screen to remove debris and substandard particles (such as pieces that are too large or too small). According to the seasoning packet formula, different dehydrated vegetables are mixed in proportion, and then the mixed dehydrated vegetables are packed into small packaging bags (usually aluminum-plastic composite film to block oxygen and moisture) by an automatic packaging machine. After sealing, they are combined with seasoning powder packets, oil packets, etc., and finally packaged into instant noodle packaging.

[0003] Currently, in the vibrating screen screening process of instant noodle seasoning packet production, dust from the dehydrated vegetables during vibration is dispersed into the air in the workshop. Therefore, a dust collection device is needed to absorb the dust dispersed in the workshop air. However, most existing dust collection devices are bucket-shaped hood structures connected to a negative pressure air path, which are suspended above the vibrating screen to absorb dust. This bucket-shaped hood structure is fixed and cannot be adjusted at will, resulting in either incomplete coverage of the vibrating screen or an excessively large negative pressure coverage area that affects the suction power of the negative pressure air path, thus affecting the dust absorption effect.

[0004] Therefore, we have made improvements to this and proposed a dust collection device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dust collection device that solves the problem that existing dust collection devices cannot arbitrarily change the negative pressure coverage area, resulting in incomplete coverage of the vibrating screen or an excessively large negative pressure coverage area affecting the suction force of the negative pressure air path, thereby affecting the dust collection effect.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a dust collection device, including a dust collection component, the inner cavity of which is provided with an expansion filter component, the expansion filter component being able to expand the dust collection component;

[0007] The dust collection component includes a top plate, a hinge plate, and a telescopic folding cloth. There are two hinge plates, which are laterally hinged to the two side walls of the top plate. There are two telescopic folding cloths, with the upper part of the two telescopic folding cloths fixedly disposed at both ends of the hinge plates. The two side walls of the telescopic folding cloths are fixedly connected to the side walls of the two hinge plates disposed at the ends of the top plate.

[0008] The expansion filter component includes a filter screen and a pneumatic telescopic rod. There are two filter screens and two pneumatic telescopic rods. The two ends of one side wall of the two filter screens are hinged together by a hinge assembly. The two ends of the other side wall of the two filter screens are hinged together with their adjacent hinge plates by a hinge assembly. The two pneumatic telescopic rods are symmetrically arranged at both ends of the top plate. The piston rod of the pneumatic telescopic rod is connected to the adjacent hinge assembly.

[0009] As a preferred embodiment, the hinge assembly includes a hinge shaft and a hinge sleeve. The filter screen is provided with mounting holes at its four corners. The hinge shaft is fixedly installed in the mounting holes. The outer wall of the hinge sleeve is fixedly installed with the piston rod of the pneumatic telescopic rod and the side wall of the hinge plate. The hinge shaft and the hinge sleeve are inserted into each other.

[0010] As a preferred embodiment, the axis of the hinge shaft is arranged parallel to the length direction of the filter screen.

[0011] As a preferred embodiment, the upper middle part of the top plate is connected to a negative pressure air pipe, which is connected to a negative pressure air path.

[0012] As a preferred embodiment, the pneumatic telescopic rod is connected to an air nozzle, which is located on the upper part of the top plate and connected to a positive pressure air circuit.

[0013] As a preferred embodiment, the bottom sidewall of the hinge plate is provided with a side feed port laterally.

[0014] This utility model has the following beneficial effects:

[0015] The pneumatic telescopic rod extends and retracts via a positive pressure air path connected to an air nozzle. A hinge assembly moves the filter plate up and down within the dust collection component's inner cavity. This movement of the filter plate expands the hinge plate outwards and contracts it inwards, controlling the area of ​​the dust collection component that can absorb dust from the dehydrated vegetables. This, in turn, controls the suction force of the negative pressure airflow. Furthermore, while the dust collection component absorbs dust from the dehydrated vegetables, the filter plate prevents large pieces of dehydrated vegetables from being sucked up along with the dust.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The expanded filter component 2 includes a filter screen plate 6 and a pneumatic telescopic rod 7. There are two filter screen plates 6 and two pneumatic telescopic rods 7. The two ends of one side wall of the two filter screen plates 6 are hinged together by a hinge assembly 8. The two ends of the other side wall of the two filter screen plates 6 are hinged together with the adjacent hinge plate 4 by the hinge assembly 8. The two pneumatic telescopic rods 7 are symmetrically arranged at both ends of the top plate 3. The piston rod of the pneumatic telescopic rod 7 is connected to the adjacent hinge assembly 8.

[0027] The sidewall of the filter screen 6 is fitted to the sidewall of the telescopic folded cloth 5.

[0028] The hinge assembly 8 includes a hinge shaft 9 and a hinge sleeve 10. The filter screen plate 6 has mounting holes 11 at its four corners. The hinge shaft 9 is fixedly installed in the mounting holes 11. The outer wall of the hinge sleeve is fixedly installed with the piston rod of the pneumatic telescopic rod 7 and the side wall of the hinge plate 4. The hinge shaft 9 and the hinge sleeve 10 are inserted into each other.

[0033] The working principle of this utility model:

[0034] The pneumatic telescopic rod 7 extends and retracts via a positive pressure air passage connected to the air nozzle 13. Through the hinge assembly 8, it drives the filter plate 6 to move up and down within the dust collection component 1. The up-and-down movement of the filter plate 6 causes the hinge plate 4 to expand outwards and contract inwards towards the dust collection component 1. By changing the size of the opening at the bottom of the dust collection component 1, the area of ​​dust that the dust collection component 1 can absorb from the dehydrated vegetables is controlled, thereby controlling the suction force of the negative pressure airflow. Furthermore, while the dust collection component 1 absorbs dust from the dehydrated vegetables, the filter plate 6 can prevent large pieces of dehydrated vegetables from being sucked up along with the dust.
