Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a dust removal and ventilation device. Background Technology

[0002] To ensure the health of workers and meet environmental emission requirements, dust removal equipment is usually installed in workplaces that generate dust.

[0003] The work area and the dust removal equipment are generally connected directly by a connecting pipe, and a fan is connected in series with the connecting pipe. With the continuous operation of the fan, the dust-laden air can smoothly enter the dust removal equipment through the connecting pipe.

[0004] However, dust will remain on the fan as it passes through. Prolonged use can cause the fan to malfunction, and in severe cases, even damage it, resulting in poor operational stability. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a dust removal and ventilation device with high stability and a compact structure.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A dust removal and ventilation device includes a cylindrical body with an opening at the upper end and an air outlet communicating with its inner cavity at the lower end. The device further includes an air inlet duct and a drainage pipe. The outer diameter of the air inlet duct is smaller than the inner diameter of the body. The air inlet duct has an annular protruding connecting edge in the middle, which is fixed to the upper port of the body and closes the upper port. The lower end of the air inlet duct is located inside the body, forming an annular drainage channel between the lower end of the air inlet duct and the inner side of the body. The drainage pipe is arc-shaped and covers the outside of the body. The outer end of the drainage pipe is away from the body and is used to communicate with the dust-generating work area. The inner end of the drainage pipe communicates with the drainage channel inside the body. The upper end of the air inlet duct is used to fix a fan, and the lower end of the body is used to connect dust removal equipment.

[0008] In the above-mentioned dust removal and ventilation device, the connecting edge is flush with the upper part of the duct, and the lower end of the air inlet is located at the lower part of the duct and is far away from the duct.

[0009] In the above-mentioned dust removal and ventilation device, the main body includes a cylindrical main body one and a cylindrical main body two. The cylindrical main body one is straight, and the cylindrical main body two is conical. The larger end of the cylindrical main body two is located at the top, and the upper end of the cylindrical main body two is fixedly connected to the lower end of the main body two and the two are in communication.

[0010] In the aforementioned dust removal and ventilation device, the aforementioned duct and air inlet are connected to the main body at one point.

[0011] In the aforementioned dust removal and ventilation device, a connecting seat is fixedly connected to one side of the main body, and the connecting seat is located at the lower part of the drainage pipe.

[0012] In the aforementioned dust removal and ventilation device, there are several connecting seats, which are evenly distributed circumferentially on one outer side of the main body.

[0013] In the aforementioned dust removal and ventilation device, the lower two ports of the main body have flanges.

[0014] In the aforementioned dust removal and ventilation device, the inner end of the drainage pipe has a smoothly transitioned guide section, which is connected to the drainage channel.

[0015] In the aforementioned dust removal and ventilation device, a flange is provided at the upper end of the air inlet duct.

[0016] In the aforementioned dust removal and ventilation device, the outer end of the drainage pipe has a flange.

[0017] Compared with existing technologies, in this dust removal and ventilation device, the outer end of the duct is connected to the dust-generating work area. During the continuous operation of the fan connected to the air inlet duct, a rapidly flowing gas is generated from top to bottom within the device. The dust-laden air at the duct is drawn by the rapidly flowing gas, ultimately ensuring that the dust-laden air is quickly discharged from the air outlet at the lower end of the device. It can be seen that the above structure can smoothly bring the dust-laden air into the dust removal equipment, and its stability is relatively high.

[0018] Meanwhile, only the drainage tube is located on the outside of the main body of the entire device, so its structure is relatively compact and has high practical value. Attached Figure Description

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figure 1 and Figure 2 and Figure 3 As shown, this dust removal and ventilation device includes a cylindrical body 1 with an opening at the top and an air outlet 1b1 at the bottom communicating with its inner cavity. It also includes an air inlet duct 2 and a drainage pipe 3. The outer diameter of the air inlet duct 2 is smaller than the inner diameter of the body 1. The air inlet duct 2 has an annular protruding connecting edge 2a in the middle, which is fixed to the upper port of the body 1 and closes the upper port. The lower end of the air inlet duct 2 is located inside the body 1, forming an annular drainage channel 4 between the lower end of the air inlet duct 2 and the inner side of the body 1. The drainage pipe 3 is arc-shaped and covers the outside of the body 1. The outer end of the drainage pipe 3 is away from the body 1 and is used to communicate with the dust-generating work area. The inner end of the drainage pipe 3 communicates with the drainage channel 4 inside the body 1. The upper end of the air inlet duct 2 is used to fix a fan, and the lower end of the body 1 is used to connect to dust removal equipment.

[0027] The inlet pipe 3 is used to connect to the dust-generating work environment, the upper end of the inlet pipe 2 is connected to the fan, and the outlet 1b1 of the main body 1 is used to connect to the dust removal equipment.

[0028] During continuous operation of the fan, a rapidly flowing airflow from top to bottom is generated within the main body 1. The dust-laden air introduced into the main body 1 through the guide pipe 3 is briefly retained in the guide channel 4, after which the dust is carried out by the rapidly flowing airflow, ultimately allowing the dust to enter the dust removal equipment stably.

[0029] Since the upper part of the main body 1 is closed by the connecting edge 2a, and the lower part of the air inlet pipe 2 extends out of the connecting edge 2a, dust will only enter the lower part of the main body 1.

[0030] The connecting edge 2a is flush with the upper part of the drain pipe 3, and the lower end of the air inlet duct 2 is located at the lower part of the drain pipe 3 and is far away from the drain pipe 3.

[0031] This structure ensures that the dust is temporarily retained in the drainage channel 4, and the dust will not overflow from the top of the body 1.

[0032] The main body 1 includes a cylindrical main body 1a and a cylindrical main body 1b. The cylindrical main body 1a is straight and the cylindrical main body 1b is conical. The larger end of the cylindrical main body 1b is located at the top and the upper end of the cylindrical main body 1b is fixedly connected to the lower end of the cylindrical main body 1a and the two are in communication.

[0033] This structure allows dust inside body 1a to smoothly enter body 2 1b.

[0034] The aforementioned drainage pipe 3 and air inlet duct 2 are connected to the main body 1a.

[0035] A connecting seat 5 is fixedly connected to the side of the main body 1a, and the connecting seat 5 is located at the lower part of the drainage tube 3.

[0036] The number of connecting seats 5 is several, and the several connecting seats 5 are evenly distributed around the outer side of the main body 1a.

[0037] The entire device can be stably installed on the corresponding frame through several connecting seats 5.

[0038] The lower port of the body 21b has a flange 6.

[0039] Flange 6 enables a stable connection between the main body 21b and the dust removal equipment.

[0040] The inner end of the drainage tube 3 has a smoothly transitioned guide section 3a, which is connected to the drainage channel 4.

[0041] The design of the guide section 3a allows dust-laden air to enter the main body 1 in a stable manner.

[0042] The upper end of the air inlet duct 2 has a flange 6.

[0043] The outer end of the drainage tube 3 has a flange 6.

[0044] In this dust removal and ventilation device, the outer end of the inlet pipe is connected to the dust-generating work area. During continuous operation of the fan connected to the air inlet duct, gas flows rapidly from top to bottom within the device. The dust-laden air at the inlet pipe is drawn by the rapidly flowing gas, ultimately ensuring that the dust-laden air is quickly discharged from the air outlet at the lower end of the device. It can be seen that the above structure can smoothly bring the dust-laden air into the dust removal equipment, and its stability is relatively high.

[0045] Meanwhile, only the drainage tube is located on the outside of the main body of the entire device, so its structure is relatively compact and has high practical value.

[0046] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
