[0003]本实用新型的目的是提供一种粉尘过滤收集装置以解决背景技术中所提及的问题
[0009] The beneficial effects of this invention are as follows: The air inlet pipe is connected to the pipe conveying plastic granules. Plastic powder enters the mounting cylinder along with the gas. The gas flows around the outer wall of the first dust collection disc and the inner wall of the mounting cylinder. Under the action of gravity, the powder falls into the collection bucket after passing through the second dust collection disc and the discharge pipe. The gas splits into two streams in the middle: the upward-flowing gas passes through the filter element and becomes clean gas, which is then discharged through the exhaust pipe; the downward-flowing gas passes through the filter and becomes clean gas, which is then discharged. When the powder in the collection bucket accumulates for a period of time, it needs to be cleaned. At this time, the drive component is activated, causing the pipe cover plate to block the lower end of the discharge pipe. The dust filtration and collection device continues to operate, and the dust temporarily accumulates in the discharge pipe. Simultaneously, the collection bucket can be removed from the mounting cylinder for cleaning without interfering with the normal operation of the production line. The advantage of this design is that it can clean the dust in the collection bucket without stopping the production line, thus improving production efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtration equipment technology, and in particular to a dust filtration and collection device. Background Technology
[0002] In industrial production, air handling containing powder is always a crucial step. For example, in plastic conveying equipment, plastic powder is mixed in with the plastic raw materials during transport through pipelines. This powder needs to be removed promptly to prevent it from adhering to the pipelines and from entering the plastic molding equipment, which could lead to a decline in the quality of the plastic products. Therefore, a dust collection device connected to the conveying pipeline is required to filter and collect the dust in the pipeline. Existing dust filtration and collection devices have a filter installed above the collection tank. Air containing dust is introduced into the filter from the inlet end, and the gas flows around the inner wall of the filter. Large dust particles fall into the collection tank under the influence of gravity, while small dust particles are filtered through the filter screen in the filter. Clean gas is then discharged from the exhaust end. However, cleaning the collection tank requires stopping the operation of the filtration and collection device before the collection tank can be removed for cleaning, which also requires the production line to stop, hindering production efficiency. Therefore, it is necessary to develop a dust filtration and collection device to solve the above problems. Utility Model Content

[0014] The present invention will be further described below with reference to the accompanying drawings:
[0015] like Figures 1 to 2 As shown, a dust filtration and collection device includes an installation cylinder 01, a first dust collection disc 02, a second dust collection disc 03, a buffer assembly 04, a filter element 05, a top cover 06, an air inlet pipe 07, an exhaust pipe 08, a filter 09, and a collection bucket 10. Both the first dust collection disc 02 and the second dust collection disc 03 are frustoconical with openings at the top and bottom, with the smaller end facing downwards. Both the first dust collection disc 02 and the second dust collection disc 03 are fixed inside the installation cylinder 01, with the first dust collection disc 02 corresponding to the upper part of the second dust collection disc 03. The buffer assembly 04 includes a discharge pipe 041, a pipe end cover 042, and a driving component 043. The upper end of the discharge pipe 041 communicates with the lower end of the second dust collection disc 03, and the pipe end cover 042... The material is rotatably installed on the lower side of the feed pipe 041. The drive component 043 is fixed on the mounting cylinder 01 and its power output end is connected to the pipe end cover plate 042. The drive component 043 drives the pipe end cover plate 042 to rotate. The top cover 06 is fixed on the upper end of the mounting cylinder 01. The filter element 05 is fixedly set between the first dust collection disc 02 and the top cover 06. The air inlet pipe 07 is connected to the mounting cylinder 01 and the air inlet end corresponds to the outer wall of the first dust collection disc 02. The exhaust pipe 08 is connected to the top cover 06. The filter 09 is fixed outside the mounting cylinder 01 and is connected to the mounting cylinder 01. The filter 09 corresponds to the lower part of the second dust collection disc 03. The collection bucket 10 is detachably installed below the mounting cylinder 01.
[0016] The air inlet pipe 07 is connected to the pipe conveying plastic granules. Plastic powder enters the mounting cylinder 01 along with the gas. The gas flows around the outer wall of the first dust collection disc 02 and the inner wall of the mounting cylinder 01. Under the action of gravity, the powder falls into the collection bucket 10 after passing through the second dust collection disc 03 and the discharge pipe 041. The gas splits into two streams in the middle: the upward gas passes through the filter element 05 and becomes clean gas, which is discharged from the exhaust pipe 08; the downward gas passes through the filter 09 and becomes clean gas, which is discharged from the exhaust pipe 08. When the powder in the collection bucket 10 accumulates for a period of time, it needs to be cleaned. At this time, the drive component 043 is activated, so that the pipe cover plate 042 blocks the lower end of the discharge pipe 041. The dust filtration and collection device continues to operate, and the dust temporarily accumulates in the discharge pipe 041. At the same time, the collection bucket 10 can be removed from the mounting cylinder 01 for cleaning without interfering with the normal operation of the production line. The advantage of this design is that it can clean the dust in the collection bucket 10 without stopping the production line, thus improving production efficiency.
[0017] The collection bucket 10 includes a bucket body 101, a locking ring 102, a handle 103, and a viewing window 104. The upper end of the bucket body 101 is detachably installed on the lower end of the mounting cylinder 01 via the locking ring 102. Two sets of handles 103 are provided and fixed on the left and right sides of the bucket body 101 respectively. The viewing window 104 is fixed on the bucket body 101.
[0018] Through the viewing window 104, the dust accumulation inside the barrel 101 can be observed, making it easy to determine whether the dust needs to be cleaned. The locking ring 102 is equipped with a locking device that drives the locking ring 102 to contract or open. When the locking ring 102 is open, the barrel 101 can be removed. The handle 103 provides a handhold for the operator, making it easy for the operator to operate.
[0019] The opening at the lower end of the feed pipe 041 is inclined, and the angle between the opening at the lower end of the feed pipe 041 and the horizontal is 40° to 50°. The inclined opening at the lower end of the feed pipe 041 can make full use of the space on one side of the feed pipe 041 for the installation of the pipe end cover plate 042, as well as the movable space of the pipe end cover plate 042, making the structure more compact and reducing the vertical height of the equipment.
[0020] The mounting cylinder 01 is provided with a first convex ring and a second convex ring. The upper outer periphery of the first dust collection disc 02 is provided with a first annular groove 021, and the upper outer periphery of the second dust collection disc 03 is provided with a second annular groove 031. The first convex ring corresponds to the first annular groove 021, and the second convex ring corresponds to the second annular groove 031.
[0021] The first dust collection tray 02 can be easily disassembled and assembled by fastening the first convex ring and the first annular groove 021, and the second dust collection tray 03 can be easily disassembled and assembled by fastening the second convex ring and the second annular groove 031.
[0022] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
