Description

Technical Field

[0001] This utility model relates to the field of industrial dust removal equipment technology, and in particular to a mobile environmental protection industrial dust removal equipment. Background Technology

[0002] In the process of rapid development of modern industrial production, many industries such as machining, chemicals, and building materials have created enormous economic value, but have also brought about serious dust pollution problems. This dust, suspended in the air, not only severely deteriorates the working environment, causing workers to be exposed to dusty conditions for extended periods, which can easily lead to respiratory diseases, pneumoconiosis, and other occupational health problems, but also, once dust enters the interior of production equipment, it accelerates the wear and tear of equipment parts, interferes with normal equipment operation, and consequently affects product quality, increasing production and equipment maintenance costs for enterprises. To address industrial dust pollution, industrial dust collection equipment has emerged and is widely used. Among them, mobile industrial dust collection equipment is particularly favored in small and medium-sized factories and in scenarios with variable production processes because it can be flexibly moved to different dust-generating points for dust collection operations without the need for complex fixed installations.

[0003] However, in terms of dust removal efficiency, many existing devices use a single filtration structure, equipped only with a simple non-woven fabric filter. This filtration method can only intercept larger dust particles. For fine dust particles, the filtration effect is very limited. These fine dust particles not only tend to remain suspended in the air for a long time, increasing the risk of being inhaled by the human body, but they can also penetrate the filter and enter the atmosphere, causing secondary pollution. In addition, after a period of use, the surface of the filter is easily clogged by dust, which causes the suction resistance of the device to increase rapidly and the suction efficiency to drop significantly.

[0024] 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.

[0025] 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.

[0026] Example 1: As Figure 1-4 As shown, this utility model provides a mobile environmental protection industrial dust removal device, including a push frame 1, a base plate 12 fixedly installed at the bottom of the push frame 1, a filter mechanism 2 provided at the top of the base plate 12, and a dust removal mechanism 3 provided at the top of the filter mechanism 2.

[0027] The filter mechanism 2 includes a filter box 21. The filter box 21 is provided with a primary filter layer 22, a medium filter layer 23 and a high-efficiency filter layer 24 arranged from bottom to top. The outer walls of the primary filter layer 22, the medium filter layer 23 and the high-efficiency filter layer 24 are all fixed to the inner wall of the filter box 21. The lower end of the filter box 21 is fixed to the upper end of the base plate 12.

[0028] The dust removal mechanism 3 includes an air tank 31, a pulse controller 32 fixedly installed on one side of the filter box 21, a vertical pipe 33 installed through the upper end of the filter box 21, a concave blowpipe 34 fixedly installed at the top inside the filter box 21, an electromagnetic pulse valve 35 fixedly installed at the upper end of the filter box 21, the lower end of the air tank 31 fixed to the upper end of the filter box 21, the upper end of the vertical pipe 33 fixed to the lower opening of the electromagnetic pulse valve 35, the lower end of the vertical pipe 33 fixed to the upper opening of the concave blowpipe 34, the air inlet of the electromagnetic pulse valve 35 connected to the air outlet of the air tank 31, and the electromagnetic pulse valve 35 electrically connected to the pulse controller 32.

[0029] The specific settings and functions of this embodiment are described below. A filter box 21 is vertically installed on the base plate 12 of the dust removal equipment. The filter box 21 is made of high-strength, corrosion-resistant stainless steel and is integrally formed. The inner wall is polished to effectively prevent dust from adhering and accumulating. The filter box 21 is equipped with a multi-layer filter assembly, which consists of a primary filter layer 22, a medium-efficiency filter layer 23, and a high-efficiency filter layer 24 arranged from bottom to top. Each filter layer is fixed by a detachable sealing frame to ensure interlayer sealing and prevent short circuit of dust-laden air.

[0030] The primary filter layer 22 is made of non-woven fabric and can filter larger dust particles; the medium-efficiency filter layer 23 is made of glass fiber filter paper and can filter medium-sized dust particles; the high-efficiency filter layer 24 is made of HEPA filter material and can filter dust particles larger than 0.3 microns with an efficiency of over 99.97%. The multi-layer filter components work together to effectively filter dust particles of different sizes and improve the dust removal effect.

[0031] The three-layer filter components work together to form a gradient filtration system: the primary filter layer 22 first intercepts large dust particles, reducing the load on subsequent filter layers; the medium-efficiency filter layer 23 further filters medium-sized dust particles; and the high-efficiency filter layer 24 focuses on capturing fine dust particles, achieving efficient interception of dust particles of different sizes, and greatly improving the overall dust removal efficiency compared to a single filtration method.

[0032] The top of the filter box 21 is equipped with an air tank 31 and an electromagnetic pulse valve 35. The air tank 31 is made of pressure vessel steel with a wall thickness of 5mm. Its volume is customized according to the air volume handled by the equipment, usually 8 to 15L. It can store compressed air with a pressure of 0.4-0.8MPa. The electromagnetic pulse valve 35 is a submerged pulse valve with good sealing and fatigue resistance.

[0033] A pulse controller 32 is installed on the side of the filter box 21. It has a built-in programmable logic controller (PLC) that can precisely control the opening and closing of the electromagnetic pulse valve 35 according to the equipment operating resistance or preset time. The pulse controller 32 and the electromagnetic pulse valve 35 are connected through a high-temperature resistant and interference-proof shielded cable to ensure stable signal transmission.

[0034] A vertical pipe 33 is installed vertically through the top of the filter box 21. The diameter of the vertical pipe 33 is designed according to the capacity of the air tank 31 and the blowing requirements, usually DN25-DN40. It is made of seamless steel pipe with a smooth inner wall to reduce airflow resistance. The lower end of the vertical pipe 33 is connected to a concave blowing pipe 34. The concave blowing pipe 34 has an overall U-shaped structure and is made of 304 stainless steel. The pipe diameter matches that of the vertical pipe 33. The pipe wall is evenly distributed with blowing holes of 8-10mm in diameter. The number of blowing holes is determined according to the number and area of ​​the filter components to ensure that each filter unit can be subjected to uniform blowing force.

[0035] When dust accumulation on the surface of the filter element causes the equipment operating resistance to reach a preset threshold, or when the cleaning cycle set by the pulse controller 32 is reached, the pulse controller 32 sends an electrical signal to the electromagnetic pulse valve 35. The electromagnetic pulse valve 35 opens rapidly, and the high-pressure compressed air in the air tank 31 quickly enters the concave blowpipe 34 through the vertical pipe 33 and is ejected at high speed from the blowpipe. The instantaneous impact of the compressed air causes the filter element to shake violently, and the dust attached to the surface is shaken off due to inertia and falls into the dust collection system below. The entire cleaning process is completed within 0.1 to 0.2 seconds, with high cleaning efficiency, which can effectively reduce the operating resistance of the equipment and extend the service life of the filter element.

[0036] Example 2: Figure 1 , Figure 2 and Figure 3 As shown, a moving mechanism 11 is fixedly installed at the lower end of the pushing frame 1, a fan mechanism 13 is installed at the upper opening of the filter box 21, a vacuum hose 14 is installed through one end of the filter box 21, a vacuum nozzle 15 is fixedly installed at the other end of the vacuum hose 14, a collection box 16 is placed at the upper end of the moving mechanism 11, a guide hopper 17 is installed at the lower end of the filter box 21, and the lower opening of the guide hopper 17 is in contact with the upper opening of the collection box 16.

[0037] The overall effect of this embodiment is that by installing a moving mechanism 11 at the lower end of the pushing frame 1, the dust removal equipment can be easily moved. A fan mechanism 13 is installed at the upper opening of the filter box 21. A suction hose 14 is installed through one end of the filter box 21, and a suction nozzle 15 is installed at the other end of the suction hose 14. The suction hose 14 is made of high-temperature resistant and anti-static PVC mesh material, and the internal spiral steel wire skeleton enhances the hose's pressure resistance. The hose can be freely extended and retracted, making it convenient for operators to move the suction nozzle 15 to different positions. For vacuuming operations, the vacuum nozzle 15 is designed in a trumpet shape to adapt to vacuuming needs at different angles. The inner side of the vacuum nozzle 15 is provided with a guide groove to guide the dust-laden airflow into the vacuum hose 14 quickly, improving vacuuming efficiency. A collection box 16 is installed at the upper end of the moving mechanism 11, and a guide hopper 17 is installed at the lower end of the filter box 21. The lower opening of the guide hopper 17 is precisely connected to the upper opening of the collection box 16. An elastic sealing ring is provided between the two to prevent dust from escaping during transmission, ensuring the sealing and high efficiency of the entire dust collection process.

[0038] The usage and working principle of this device are as follows: First, the negative pressure generated by the operation of the fan mechanism 13 is transmitted to the dust suction hose 14 and the dust suction nozzle 15 through the pipe. When the dust suction nozzle 15 is close to the dust source, under the action of negative pressure, the dust-laden air quickly enters the dust suction hose 14 through the guide groove. The spiral steel wire skeleton inside the dust suction hose 14 can maintain its shape stability under negative pressure and will not collapse due to pressure, ensuring that the dust-laden air is smoothly delivered to the filter box 21.

[0039] After dusty air enters the filter box 21, it first passes through the pre-filter layer 22. Larger dust particles are directly intercepted by the non-woven fabric filter due to inertia. The remaining dusty air continues to rise and enters the medium-efficiency filter layer 23. The fine structure of the glass fiber filter paper captures medium-sized dust particles of 1-5μm. Finally, the air that has passed through the first two filters reaches the high-efficiency filter layer 24. The H13 grade HEPA filter material uses the principles of Brownian motion, interception, and inertial collision to efficiently filter fine dust particles larger than 0.3μm, so that the purified air is discharged from the top of the filter box 21.

[0040] During the operation of the filtration system, the dust intercepted on the surface of the filter layer is shaken off by the dust removal mechanism 3 (such as pulse jet cleaning). Under the action of gravity, the dust falls into the guide hopper 17, which is shaped like an inverted truncated cone at the lower end of the filter box 21. The dust will slide down quickly along the inner wall and enter the collection box 16 through the opening at the lower end of the guide hopper 17. This allows for the centralized collection of dust, making it convenient for staff to pull the collection box 16 and remove it from the moving mechanism 11 for easy cleaning of the dust inside.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the 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 this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
