Description

Technical Field

[0001] The utility model relates to the technical field of filter cartridge pre-treatment, in particular to a filter cartridge pre-treatment device for gas sampling. Background Art

[0002] When analyzing and detecting heavy metals and particulate matter in the flue, it is necessary to sample the gas in the flue. Sampling requires a sampling gun. A filter cartridge made of glass fiber is set at the front end of the sampling gun to filter dust and heavy metal particles in the flue. The filter cartridge needs to be processed before use. For the filter cartridge before sampling, a special brush should be used to brush off the burrs on the surface to ensure that the filter cartridge surface does not "fall off" during the weighing and sampling process, which affects the accuracy of the data.

[0003] When removing burrs from existing filter cartridges, a manual handheld brush is usually used to clean the filter cartridge surface. Some of the burrs brushed off from the inside of the filter cartridge will still fall into the inside of the filter cartridge, making it inconvenient to collect the brushed off burrs when brushing. Moreover, when brushing manually, the force used is not constant, resulting in poor cleaning effect on the filter cartridge surface. Utility Model Content

[0004] The utility model aims to provide a filter cartridge pre-treatment device for gas sampling to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A filter cartridge pretreatment device for gas sampling comprises a base plate, a rolling assembly is symmetrically fixedly mounted on the upper surface of the base plate, the rolling assembly comprises two groups of support plates symmetrically fixedly mounted on the upper surface of the base plate, rollers are rotatably connected between each group of support plates, clamping plates are symmetrically slidably connected to the outer sides of the rollers, a clamping assembly is installed between a group of support plates, the clamping assembly comprises a bidirectional screw rod rotatably connected between a group of support plates, a cleaning assembly is fixedly mounted on the upper surface of the base plate, the cleaning assembly comprises two collecting frames fixedly mounted on the upper surface of the base plate and fixedly connected by a telescopic plate, a cleaning roller is rotatably connected inside the collecting frame, and comb teeth are fixedly mounted on the inner surface of the collecting frame.

[0007] Furthermore, one end of each of the two rotating rollers is fixedly mounted with a first pulley, and a first transmission belt is movably sleeved on the outer sides of the two first pulleys.

[0008] Furthermore, a motor No. 1 is fixedly mounted on one side surface of the support plate, an output end of the motor No. 1 is fixedly connected to a roller, and a plurality of balls are movably embedded and mounted on one side surface of the clamping plate.

[0009] Furthermore, the bidirectional screw rod passes through the two clamps and is movably engaged with the two clamps, a slide plate is fixedly installed between the two groups of support plates, the slide plate passes through the clamps and is slidably connected with the clamps, a No. 2 motor is fixedly installed on one side surface of one support plate, and the output end of the No. 2 motor is fixedly connected to the bidirectional screw rod.

[0010] Furthermore, one end of each of the two cleaning rollers is fixedly mounted with a No. 2 pulley, the outer movable sleeves of the two No. 2 pulleys are provided with a No. 2 transmission belt, one end of a collecting frame is fixedly mounted with a No. 3 motor, and the output end of the No. 3 motor is fixedly connected to a cleaning roller.

[0011] Furthermore, a support frame is fixedly installed on the upper surface of the base plate, a hollow screw is screwed and connected to the upper surface of the support frame, and the hollow screw passes through the support frame, a sliding rod is slidably connected inside the hollow screw, a U-shaped frame is fixedly installed on the lower end of the sliding rod, and a pressure roller is rotatably connected inside the U-shaped frame.

[0012] Preferably, a spring is disposed on the outer movable sleeve of the slide rod, and two ends of the spring are fixedly connected to the U-shaped frame and the hollow screw rod respectively.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By running the No. 1 motor, the two rollers rotate in the same direction to push the filter cartridge to rotate. The No. 2 motor runs to move the two clamps toward each other to limit the position of the filter cartridge. At this time, the ball presses against both ends of the filter cartridge to reduce the friction between the clamps and the filter cartridge. After the filter cartridge is installed between the two rollers, turn the hollow screw to drive the U-shaped frame downward and gently press the pressure roller against the surface of the filter cartridge. The spring makes the U-shaped frame always have a downward force, increasing the pressure of the pressure roller on the filter cartridge within a certain elastic range, thereby increasing the friction between the filter cartridge and the roller, avoiding the filter cartridge from slipping and allowing the filter cartridge to rotate smoothly.

[0015] 2. The No. 3 motor is running, and the two cleaning rollers are rotated synchronously through the transmission of the No. 2 pulley and the No. 2 transmission belt. The rotation direction is opposite to that of the filter cartridge, so that the bristles on the surface of the cleaning roller sweep the surface of the filter cartridge, sweep away the burrs on the surface of the filter cartridge, and then when the cleaning roller moves with the swept burrs to the comb teeth, the comb teeth scrape the burrs into the collection frame, thereby driving the filter cartridge to rotate through the rolling assembly, so that the cleaning assembly brushes the inner and outer surfaces of the filter cartridge with the same force, replacing manual brushing, improving the cleaning effect of the filter cartridge surface, and avoiding damage to the filter cartridge caused by large manpower, and facilitating the collection of the brushed burrs during brushing, so as to avoid the brushed burrs falling into the filter cartridge, reducing the influence of the burrs on the sampling accuracy.

[0025] Embodiment 1

[0026] like Figure 1-4 As shown, in this embodiment, a No. 1 pulley 205 is fixedly installed at one end of the two rollers 202, and a No. 1 transmission belt 206 is movably sleeved on the outer side of the two No. 1 pulleys 205; a No. 1 motor 207 is fixedly installed on the surface of one side of a support plate 201, and the output end of the No. 1 motor 207 is fixedly connected to a roller 202, and a plurality of balls 204 are movably embedded and installed on the surface of one side of a splint 203; a bidirectional screw rod 301 passes through the two splints 203 and is movably engaged with the two splints 203, a slide plate 302 is fixedly installed between the two groups of support plates 201, the slide plate 302 passes through the splint 203 and is slidably connected to the splint 203, a No. 2 motor 303 is fixedly installed on the surface of one side of a support plate 201, and the output end of the No. 2 motor 303 is fixedly connected to the bidirectional screw rod 301.

[0027] In this embodiment, the No. 1 motor 207 is running, and through the transmission of the No. 1 pulley 205 and the No. 1 transmission belt 206, the two rollers 202 rotate in the same direction, pushing the filter cartridge to rotate, and the No. 2 motor 303 is running, driving the bidirectional screw rod 301 to rotate, and through the screw connection with the two clamping plates 203, the two clamping plates 203 move toward each other to limit the position of the filter cartridge. At this time, the ball 204 presses against the two ends of the filter cartridge to reduce the friction between the clamping plates 203 and the filter cartridge, so that the filter cartridge can rotate smoothly.

[0028] like Figure 3-5 As shown, in this embodiment, two cleaning rollers 402 are fixedly mounted with a No. 2 pulley 403 at one end, a No. 2 transmission belt 404 is movably sleeved on the outer sides of the two No. 2 pulleys 403, a No. 3 motor 405 is fixedly mounted at one end of a collecting frame 401, and the output end of the No. 3 motor 405 is fixedly connected to a cleaning roller 402.

[0030] Embodiment 2

[0031] On the basis of the first embodiment, in order to solve the problem that the filter cartridge in the first embodiment is easy to slip on the surface of the roller 202 .

[0033] During specific implementation, after the filter cartridge is installed between the two rollers 202, the hollow screw 102 is turned to make the hollow screw 102 drive the U-shaped frame 104 to move downward, and the pressure roller 105 is lightly pressed against the surface of the filter cartridge. The spring 106 ensures that the U-shaped frame 104 always has a downward force, thereby increasing the pressure of the pressure roller 105 on the filter cartridge within a certain elastic range, thereby increasing the friction between the filter cartridge and the roller 202, preventing the filter cartridge from slipping, and allowing the filter cartridge to rotate smoothly.
