Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, and in particular to a dust suppression device for municipal engineering. Background Technology

[0002] During the construction or renovation of municipal engineering projects, dust will be generated. In order to avoid the large amount of dust from causing adverse effects on the air environment, dust suppression devices are usually used to suppress dust, thereby protecting the environment and improving construction conditions.

[0003] Therefore, a dust suppression device for municipal engineering, with publication number CN217855280U, includes a treatment cylinder, a support rod, and a base connected from top to bottom. The side wall of the treatment cylinder is provided with several suction pipes. Inside the treatment cylinder, there is a vertically arranged filter cylinder, a fan located inside the filter cylinder, a cleaning component for cleaning the outer wall of the filter cylinder, and a drive mechanism for driving the cleaning component to rotate around the filter cylinder. At least two discharge ports are opened at the bottom of the treatment cylinder, and a dust collection box placed on the base is located below the discharge ports. After the dust suppression device is placed in the position of use, the fan and the dual-shaft motor are started. The dust-laden gas from the outside enters the interior of the treatment cylinder through the suction pipes. The filter cylinder inside the treatment cylinder purifies the dust-laden gas. Large dust particles fall to the bottom of the treatment cylinder due to gravity, while small dust particles are adsorbed on the outer wall of the filter cylinder. The drive mechanism drives the track to rotate around the filter cylinder, and the track cleans the filter cylinder. The cleaned dust falls into the receiving cavity.

[0004] The filter cartridge in this device uses tiny pores on the filter media to intercept dust and other particulate matter. When dust-laden gas passes through the filter cartridge, dust particles are adsorbed or intercepted under various effects. However, some fine particles may adhere to the inside of the pores under electrostatic adsorption and other effects. Over time, they will accumulate in the pores, leading to increased resistance of the filter cartridge and affecting filtration efficiency. Utility Model Content

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figure 1-4As shown, a dust suppression device for municipal engineering includes a treatment tank 1 and an outer filter cartridge 16. The outer filter cartridge 16 is fixedly installed inside the treatment tank 1. The bottom of the outer filter cartridge 16 is hollowed out. A bottom cover 6 is fixedly connected to the bottom of the treatment tank 1 by bolts. The bottom cover 6 abuts against the bottom of the outer filter cartridge 16. An inner filter cartridge 7 is rotatably connected to the inner side of the outer filter cartridge 16. A toothed ring 11 is fixedly installed inside the outer filter cartridge 16 and below the inner filter cartridge 7. The toothed ring 11 has inward-facing teeth and is meshed with a gear 8. The gear 8 and the inner filter cartridge 7 are movably installed. Several evenly distributed rubber columns 4 are fixedly connected to the outer side of the inner filter cartridge 7 and the inner side of the outer filter cartridge 16. The rubber columns 4 on the outer side of the inner filter cartridge 7 are used to insert into the filter holes of the outer filter cartridge 16, and the rubber columns 4 on the inner side of the outer filter cartridge 16 are used to insert into the filter holes of the inner filter cartridge 7.

[0026] In this technical solution, by setting rubber columns 4, when the inner filter cartridge 7 rolls inside the outer filter cartridge 16, the rubber columns 4 in the same vertical column are inserted into the filter holes, pushing out the dust particles remaining in the filter holes. By setting a bottom cover 6, the dust pushed out from the filter holes of the outer filter cartridge 16 falls onto the bottom cover 6. During cleaning, the bottom cover 6 can be removed by turning the bolts. By setting a toothed ring 11 and a gear 8, when the gear 8 rotates, it will roll along the toothed ring 11, driving the inner filter cartridge 7 to rotate along the inner side of the outer filter cartridge 16. In addition, the number and position of the rubber columns 4 match the number and position of the filter holes on the inner filter cartridge 7 and the outer filter cartridge 16.

[0027] like Figure 5 As shown, the bottom of the inner filter cartridge 7 is provided with a base plate 14, the top of the gear 8 is provided with a dual-axis motor 12, the top of the dual-axis motor 12 is fixedly connected with an electric push rod 13, the telescopic end of the electric push rod 13 is fixedly connected with the base plate 14, a collar 10 is slidably installed on the gear ring 11, the housing part of the dual-axis motor 12 and the collar 10 are fixedly fitted, one of the main shafts of the dual-axis motor 12 is fixedly connected with the gear 8, and the other main shaft is fixedly connected with the electric push rod 13. The bottom surface of the inner filter cartridge 7 is hollowed out and the hollowed-out edge is concave to form a step 15, and the base plate 14 and the step 15 abut against each other.

[0028] In this technical solution, a dual-axis motor 12 drives the gear 8 and the electric push rod 13 to rotate. The rotation of the electric push rod 13 causes the inner filter cartridge 7 to rotate through the contact force between the base plate 14 and the step 15. In conjunction with the gear 8, the inner filter cartridge 7 rolls along the inner side of the outer filter cartridge 16. The base plate 14 is used to receive dust particles pushed out from the filter holes of the inner filter cartridge 7. The electric push rod 13 pushes the base plate 14 to rise and fall. When the base plate 14 falls, the base plate 14 and the step 15 do not contact each other. At this time, the dual-axis motor 12 works, only driving the base plate 14 to move, which can throw the dust that falls on the base plate 14 onto the bottom cover 6.

[0029] like Figure 5As shown, a rotating plate 9 is rotatably connected to the top of the outer filter cartridge 16, and a connecting pipe 3, which is fixedly connected to the inner filter cartridge 7, is rotatably connected to one side of the rotating plate 9 at an eccentric position. A curved pipe 2 for communicating with the fan is connected to the connecting pipe 3.

[0030] In this technical solution, a connecting pipe 3 is provided to support the inner filter cartridge 7, and a rotating plate 9 is provided to support the connecting pipe 3. When the inner filter cartridge 7 rolls, the movement trajectory of the connecting pipe 3 is circular. The rotating plate 9 is provided to support the movement of the connecting pipe 3. A curved pipe 2 is provided to connect the fan and the connecting pipe 3, and the purified air is discharged through the fan.

[0031] like Figure 4 As shown, two sets of fixing rods 5 arranged in a ring array are inserted into the inner side of the treatment tank 1. One set of fixing rods 5 is inserted and fixed to the top side of the outer filter cylinder 16, and the other set of fixing rods 5 is fixedly connected to the bottom side of the outer filter cylinder 16 and extends to the toothed ring 11.

[0032] In this technical solution, there are several fixing rods 5 in a set, and the fixing rods 5 in a set are set at the same height. By setting the fixing rods 5, the outer filter cartridge 16, toothed ring 11 and processing bucket 1 are fixed. When dust particles fall, they can fall smoothly onto the bottom cover 6 without being easily blocked.

[0033] Working principle: Dust-laden gas enters the treatment chamber 1 through the inlet. The fan operates, drawing the gas through the filter holes into the outer filter cartridge 16 and the inner filter cartridge 7, and then discharges it from the fan through the connecting pipe 3 and the curved pipe 2. When cleaning the filter cartridges of this device, the dual-shaft motor 12 drives the gear 8 and the electric push rod 13 to rotate. The gear 8 rotates and rolls along the gear ring 11, causing the inner filter cartridge 7 to rotate along the inner side of the outer filter cartridge 16. The electric push rod 13 rotates and drives the inner filter cartridge 7 to rotate through the abutting force between the base plate 14 and the step 15. The electric push rod 13 and the gear 8 cooperate to make the inner filter cartridge 7 roll along the inner side of the outer filter cartridge 16, thereby causing the rubber column 4 to be inserted into the filter hole and push out the dust particles remaining in the filter hole.

[0034] The wiring diagrams of the dual-axis motor 12 and electric push rod 13 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the dual-axis motor 12 and electric push rod 13 will not be explained in detail.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
