Description

Technical Field

[0001] This utility model belongs to the field of dust monitoring technology, and in particular relates to a dust monitoring device for workshop air purification. Background Technology

[0002] According to the authorized patent CN209501062U, this application describes a dust monitoring device. By incorporating a dust detector, the dust processing cylinder is equipped with a dust handling unit capable of detecting dust content. Furthermore, the inclusion of a drive motor and a water pump enables dust processing, thus solving the problem that general dust monitoring devices only detect dust and cannot effectively treat it. However, it still has the following shortcomings:

[0003] The device uses water as the dust treatment fluid, which is environmentally friendly. However, the use of water may be limited in certain special environments (such as high or low temperature environments). Furthermore, after the dust is wetted, it may form a mud-like substance, which may cause secondary pollution if not handled properly. Utility Model Content

[0004] The purpose of this invention is to provide a dust monitoring device for workshop air purification. Specifically, by setting up a filter screen and dust collection bags, the fan is activated to allow dust-laden air to enter the filter box through the air inlet. The filter screen filters out larger dust particles, while finer dust particles adhere to the surface of the dust collection bags. The filtered air is then sent out from the back of the filter box by the fan. After filtration, a high-pressure air pump is activated to allow high-pressure gas to enter the air pipe through the connecting pipe and then be ejected from the nozzle, cleaning the fine dust particles adhering to the outer surface of the dust collection bags. The dust falls into the dust collection drawer below. This method filters the air and collects the dust, solving the problems of limitations and potential secondary pollution associated with existing dust monitoring devices that use water as a dust treatment solution.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a dust monitoring device for workshop air purification, comprising a filter box and a dust monitor. The left side of the dust monitor is fixedly connected to the right side of the filter box. An air inlet is fixedly connected to the front of the filter box. A filter screen is installed inside the filter box near the air inlet, and a dust collection bag is installed behind the filter screen. A fan is fixedly connected to the back of the filter box. A cleaning component is installed above the dust collection bag. The cleaning component includes an air pipe, and several air nozzles are fixedly connected to the bottom of the air pipe. The right side of the air pipe passes through the right side of the filter box and extends to the outside. A connecting pipe is fixedly connected to the right side of the air pipe. A high-pressure air pump is fixedly connected to the side of the connecting pipe away from the air pipe. The bottom of the high-pressure air pump is fixedly connected to the top of the filter box. By using the filter screen and dust collection bag to filter the air and collect the dust, this device solves the problem that using water as a dust treatment liquid has certain limitations and may cause secondary pollution, thus improving the dust treatment efficiency.

[0007] Furthermore, four slide rails are fixedly connected inside the filter box, and sliders are slidably connected to the inner wall of the slide rails. The two sliders at the front are fixedly connected to the top and bottom of the filter screen on their corresponding sides, respectively. The design of the slide rails and sliders makes it easy to install and remove the filter screen and dust collection bag, and facilitates regular replacement or cleaning of the filter screen, thereby ensuring the efficient operation of the filtration system.

[0008] Furthermore, each of the two sliders located at the rear has a support frame fixedly connected to one side. The two support frames are respectively fixedly connected to the top and bottom of the dust collector bag. The support frames provide stable support for the dust collector bag, preventing it from shifting or deforming due to wind pressure or gravity during the filtration process, thus ensuring the stability of the dust removal effect.

[0009] Furthermore, a fixing block is fixedly connected to one side of each of the two slide rails located below. A rod is fixedly connected to the top of the fixing block. A limit plate is inserted into the outer surface of the rod. The limit plate is connected to the fixing block through the rod. This can limit the movement range of the slider on the slide rail, prevent the filter screen or dust collector bag from moving excessively and falling out of the predetermined position, and improve the stability and reliability of the entire filtration system.

[0010] Furthermore, the limiting plate is configured as an L-shape, with the right side of the limiting plate contacting the left side of the two sliders located below. The L-shaped limiting plate design is more compact and easier to manufacture, while effectively limiting the movement range of the sliders, ensuring that the filter screen and dust collection bag maintain a stable position during the filtration process.

[0011] Furthermore, trapezoidal grooves are fixedly connected inside the filter box near the filter screen and below the dust collection bag. The bottom of the slide rail located below is fixedly connected to the top of the trapezoidal groove. The trapezoidal groove provides additional support for the slide rail. The design of the trapezoidal groove also helps to guide dust into the dust collection drawer while preventing the dust in the dust collection drawer from being blown up by the wind, thus improving the reliability of dust filtration.

[0012] Furthermore, a dust collection drawer is provided below the trapezoidal groove. The outer surface of the dust collection drawer is slidably connected to the inner wall of the filter box. The design of the dust collection drawer facilitates the collection and treatment of dust generated during the filtration process. Users can easily remove and clean the collected dust by sliding the dust collection drawer, avoiding the accumulation of dust and secondary pollution in the filter box.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, by setting up a filter screen and dust collection bags, specifically involves starting a fan to allow dust-laden air to enter the filter box through the air inlet. The filter screen filters out larger dust particles, while fine dust particles adhere to the surface of the dust collection bags. The filtered air is then sent out from the back of the filter box by the fan. After filtration, a high-pressure air pump is started to allow high-pressure gas to enter the air pipe through the connecting pipe and then be sprayed out from the nozzle, cleaning the fine dust particles adhering to the outer surface of the dust collection bags. The dust falls into the dust collection drawer below. In this way, the air is filtered and the dust is collected, solving the problem that using water as a dust treatment liquid has certain limitations and may cause secondary pollution, thus improving the dust treatment efficiency.

[0015] 2. This utility model, by setting a limiting plate, allows for easy cleaning and replacement of the filter screen or dust collector bag when the filter screen or dust collector bag needs to be cleaned or replaced. The limiting plate is then removed from the box door to release the limiting of the slider. The filter screen or dust collector bag is then pulled to allow the slider to slide on the inner wall of the slide rail, thus removing the filter screen or dust collector bag for cleaning and replacement. This facilitates the cleaning and replacement of the filter screen and dust collector bag and improves the convenience of the device.

[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

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1-5As shown, this utility model is a dust monitoring device for workshop air purification, including a filter box 1 and a dust monitor 2. The left side of the dust monitor 2 is fixedly connected to the right side of the filter box 1. An air inlet 11 is fixedly connected to the front of the filter box 1. A filter screen 132 is provided inside the filter box 1 near the air inlet 11. A dust collection bag 134 is provided behind the filter screen 132. A fan 15 is fixedly connected to the back of the filter box 1. A cleaning component 14 is provided above the dust collection bag 134. The cleaning component 14 includes an air pipe 141. Several air nozzles 142 are fixedly connected to the bottom of the air pipe 141. The right side of the air pipe 141 passes through the right side of the filter box 1 and extends to the outside. A connecting pipe 143 is fixedly connected to the right side of the air pipe 141. A high-pressure air pump 14 is fixedly connected to the side of the connecting pipe 143 away from the air pipe 141. 4. The bottom of the high-pressure air pump 144 is fixedly connected to the top of the filter box 1. By setting up a filter screen 132 and a dust collection bag 134, specifically, the fan 15 is started to allow air containing dust to enter the filter box 1 from the air inlet 11. After the filter screen 132 filters out the larger dust particles, the fine dust particles are attached to the surface of the dust collection bag 134. The filtered air is then sent out from the back of the filter box 1 by the fan 15. After filtration, the high-pressure air pump 144 is started to allow high-pressure gas to enter the air pipe 141 through the connecting pipe 143 and then be sprayed out from the nozzle 142 to clean the fine dust particles attached to the outer surface of the dust collection bag 134. In this way, the air is filtered and the dust is collected, which solves the problem that using water as a dust treatment liquid has certain limitations and may cause secondary pollution, thus improving the dust treatment efficiency.

[0027] The filter box 1 has four slide rails 13 fixedly connected inside, and sliders 131 are slidably connected to the inner wall of the slide rails 13. The two sliders 131 at the front are fixedly connected to the top and bottom of the filter screen 132 on their corresponding sides.

[0028] The two sliders 131 at the rear are fixedly connected to support frames 133 on their respective sides, and the two support frames 133 are fixedly connected to the top and bottom of the dust collector bag 134 on their respective sides.

[0029] Each of the two slide rails 13 located below has a fixed block 16 fixedly connected to one side of the corresponding side. A rod 161 is fixedly connected to the top of the fixed block 16, and a limit plate 162 is inserted into the outer surface of the rod 161.

[0030] The limiting plate 162 is L-shaped, with its right side contacting the left side of the two sliders 131 located below. Specifically, by setting the limiting plate 162, when it is necessary to clean or replace the filter screen 132 or the dust collector bag 134, the door 12 is opened, the limiting plate 162 is removed, the limiting of the sliders 131 is released, and then the filter screen 132 or the dust collector bag 134 is pulled, causing the sliders 131 to slide on the inner wall of the slide rail 13, so that the filter screen 132 or the dust collector bag 134 can be removed for cleaning and replacement. This facilitates the cleaning and replacement of the filter screen 132 and the dust collector bag 134, and improves the convenience of the device.

[0031] Inside the filter box 1, near the filter screen 132 and the dust collector bag 134, there are trapezoidal grooves 17 fixedly connected. The bottom of the slide rail 13 located below is fixedly connected to the top of the trapezoidal groove 17.

[0032] A dust collection drawer 18 is provided below the trapezoidal groove 17, and the outer surface of the dust collection drawer 18 is slidably connected to the inner wall of the filter box 1.

[0033] A specific application of this embodiment is as follows: When the dust monitor 2 (model SIBATA-LD-5R) detects excessive dust concentration, the fan 15 is activated to allow dust-laden air to enter the filter box 1 through the inlet 11. The filter screen 132 filters out larger dust particles, while fine dust particles adhere to the surface of the dust collector bag 134. The filtered air is then expelled from the back of the filter box 1 by the fan 15. After filtration, the high-pressure air pump 144 is activated to allow high-pressure gas to enter the air pipe 141 through the connecting pipe 143 and then be ejected from the nozzle 142 to clean the fine dust particles adhering to the outer surface of the dust collector bag 134. The filtered and cleaned dust then passes through the filter screen 132. The trapezoidal groove 17 below the dust collector bag 134 falls into the dust collection drawer 18. This solves the problem that using water as a dust treatment liquid is limited and may cause secondary pollution. Then, pull the dust collection drawer 18 to slide it on the inner wall of the filter box 1 to remove the dust collection drawer 18 for further treatment of the dust. When it is necessary to clean or replace the filter screen 132 or the dust collector bag 134, open the box door 12, remove the limit plate 162 to release the limit on the slider 131, and then pull the filter screen 132 or the dust collector bag 134 to slide the slider 131 on the inner wall of the slide rail 13 to remove the filter screen 132 or the dust collector bag 134 for cleaning or replacement.
