Description

Technical Field

[0001] The utility model relates to the technical field of dust collecting devices, in particular to a dust collecting device with an adjustable internal air pressure structure. Background Art

[0002] The new energy die-cutting process involves a cutting process, which will generate cuttings and dust when cutting materials. In order to protect the processing environment and the health of workers, a dust suction device is required to absorb the cuttings and dust generated by the cutting.

[0003] Currently, vacuum cleaners on the market usually use mechanical suction. The suction force can be adjusted by adjusting the power of the fan, but there are usually only two or three gears with a small adjustment range. There may be problems with insufficient suction or excessive suction, resulting in poor cleaning effects and difficulty in adapting to different production situations. Utility Model Content

[0004] The utility model aims to provide a dust suction device with an adjustable internal air pressure structure, which has a wide suction force adjustment range and can be suitable for different situations.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A dust collecting device with an adjustable internal air pressure structure comprises a body, an air inlet connection port is arranged on the top of the body, a shell is installed on the outer surface of the body, a filter is arranged at the connection between the shell and the air inlet connection port, a fan is installed on the outer surface of the shell, and an air outlet pipe is arranged at the end of the fan. Two sealing plates are symmetrically installed inside the body, side plates are installed on the opposite surfaces of the two sealing plates, and a flap is rotatably installed between the two side plates through a connecting shaft.

[0007] It can be seen that the sealing plate has a sealing effect on the interior of the machine body, so that the air can only flow between the two side panels. When the suction needs to be adjusted, it is only necessary to rotate the connecting shaft to drive the flap to rotate, so that the space for air circulation changes. When the circulation space becomes larger, the air flow speed is lower and the suction is relatively weak. When the circulation space is smaller, the air flow speed is higher and the suction is relatively strong. Therefore, the purpose of wind speed regulation is achieved, and the adjustment range is wide.

[0008] Furthermore, a mounting box is installed on the outer surface of the machine body, and the end of the connecting shaft passes through the mounting box. A worm wheel is sleeved on the outer surface of the connecting shaft. A worm is penetrated and rotatably connected to the inside of the mounting box, and the worm is meshingly connected to the worm wheel.

[0009] Due to the meshing relationship between the worm and the worm wheel, the connecting shaft can be driven to rotate when the worm is rotated, thereby driving the flap to flip and achieving the purpose of suction adjustment. In addition, the worm and the worm wheel are self-locking, so the flap can be prevented from angular deflection under the action of wind.

[0010] Furthermore, an observation window is provided on the outer surface of the body, and the observation window and the filter are at the same height.

[0011] The setting of the observation window makes it convenient for workers to observe the use of the filter from the outside, and when there is a lot of dust attached to the surface, it can be cleaned in time.

[0012] Furthermore, two electric push rods are symmetrically installed on the upper surface of the shell, and a connecting plate is commonly installed at the ends of the telescopic ends of the two electric push rods. A blowing pipe is vertically installed on the connecting plate. The bottom of the blowing pipe passes through the shell and a cross pipe is horizontally installed. Multiple nozzles are evenly installed on the side of the cross pipe facing the filter, and a corrugated pipe is connected to the top of the blowing pipe.

[0013] When it is necessary to clean the dust attached to the surface of the filter, the electric push rod can be started, and its telescopic end drives the connecting plate to rise and fall, and drives the blowing pipe and the cross pipe to rise and fall. By connecting the bellows to the external air source, when the gas enters the cross pipe, it is sprayed out from multiple nozzles, so the filter can be back-blown to blow away the dust attached to the surface of the filter, thereby achieving the purpose of automatic cleaning.

[0014] Furthermore, a dust collecting box is arranged at the bottom of the machine body, and an inspection door is arranged at a position on the outer surface of the machine body corresponding to the dust collecting box.

[0015] Dust can be collected by setting up a dust box. When a certain amount of dust is collected, the inspection door can be opened to clean the dust box.

[0016] Furthermore, slide grooves are vertically opened on the inner walls of both sides of the shell, and sliding blocks are installed at both ends of the horizontal tube in the length direction, and the sliding blocks are arranged in the slide grooves.

[0017] By setting the slide groove and the slider, the cross pipe can be limited and guided, so that the cross pipe is smoother and more stable when it is raised or lowered. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The utility model is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, a dust collecting device with an adjustable internal air pressure structure includes a body 100, an air inlet connection port 101 is arranged on the top of the body 100, a shell 102 is installed on the outer surface of the body 100, a filter screen 103 is arranged at the connection between the shell 102 and the air inlet connection port 101, a fan 104 is installed on the outer surface of the shell 102, and an air outlet pipe 105 is arranged at the end of the fan 104. Two sealing plates 106 are symmetrically installed inside the body 100, and side plates 107 are installed on the opposite surfaces of the two sealing plates 106, and a flap 109 is rotatably installed between the two side plates 107 through a connecting shaft 108.

[0026] When in use, connect the dust suction pipe to the air inlet connection port 101, and then start the fan 104. The suction force of the fan 104 acts on the end of the dust suction pipe to achieve the dust suction effect. The dust-containing air entering the body 100 flows downward between the two side panels 107, and is discharged from the air outlet pipe 105 after being filtered by the filter screen 103. When the suction force needs to be adjusted, the connecting shaft 108 can be rotated to drive the flap 109 to rotate, so that the space for air circulation can be changed. When the circulation space becomes larger, the air flow speed is lower and the suction force is relatively weaker. When the circulation space is smaller, the air flow speed is higher and the suction force is relatively strong. Therefore, the purpose of wind speed regulation is achieved, and the adjustment range is wide. It is worth mentioning that the outer surfaces of the four sides of the body 100 are provided with air inlet connection ports 101, which are used to connect with the dust suction pipe from multiple directions, which is convenient for the placement and layout of the equipment and is sealed when not in use.

[0027] Specifically, an installation box 200 is installed on the outer surface of the body 100, and the end of the connecting shaft 108 passes through the installation box 200, and a worm wheel 201 is sleeved on the outer surface of the connecting shaft 108. A worm 202 passes through the interior of the installation box 200 and is rotatably connected. The worm 202 is meshingly connected to the worm wheel 201. Due to the meshing relationship between the worm 202 and the worm wheel 201, when the worm 202 is rotated, the connecting shaft 108 can be driven to rotate, thereby driving the flap 109 to flip, thereby achieving the purpose of suction adjustment, and the worm 202 and the worm wheel 201 are self-locking, so that the flap 109 can be prevented from angular deflection under the action of wind.

[0028] Specifically, an observation window 300 is provided on the outer surface of the body 100, and the observation window 300 and the filter 103 are at the same height. The setting of the observation window 300 is convenient for workers to observe the use of the filter 103 from the outside, and when there is a lot of dust attached to the surface, it can be cleaned in time.

[0029] Specifically, two electric push rods 400 are symmetrically installed on the upper surface of the shell 102, and a connecting plate 401 is commonly installed at the ends of the telescopic ends of the two electric push rods 400, and a blowing pipe 402 is vertically installed on the connecting plate 401, and the bottom of the blowing pipe 402 penetrates into the shell 102 and is horizontally installed with a cross pipe 403, and a plurality of nozzles 404 are evenly installed on the side of the cross pipe 403 facing the filter 103, and a bellows 405 is connected to the top of the blowing pipe 402. When it is necessary to clean the dust attached to the surface of the filter 103, the electric push rod 400 can be started, and its telescopic end drives the connecting plate 401 to rise and fall, and drives the blowing pipe 402 and the cross pipe 403 to rise and fall. By connecting the bellows 405 to an external air source, when the gas enters the cross pipe 403, it is sprayed from the plurality of nozzles 404, so that the filter 103 can be back-blown to blow away the dust attached to the surface of the filter 103, thereby achieving the purpose of automatic cleaning.

[0030] Specifically, a dust box 500 is provided at the bottom of the body 100, and an inspection door 501 is provided on the outer surface of the body 100 corresponding to the dust box 500. Through the setting of the dust box 500, dust can be collected. When a certain amount of dust is collected, the inspection door 501 can be opened to clean the dust box 500.

[0031] Specifically, the inner walls on both sides of the shell 102 are vertically opened with sliding grooves 600, and sliders 601 are installed at both ends of the length direction of the cross tube 403. The sliders 601 are set in the sliding grooves 600. Through the setting of the sliding grooves 600 and the sliders 601, the cross tube 403 can be limited and guided, so that the cross tube 403 is smoother and more stable when rising and falling.

[0032] The above is a detailed description of the utility model in combination with specific embodiments, and it cannot be determined that the specific implementation methods of the utility model are limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, making several equivalent substitutions or obvious modifications without departing from the concept of the utility model, and having the same performance or use, should be regarded as belonging to the patent protection scope of the utility model determined by the submitted claims.
