Description

Technical Field

[0001] The utility model relates to the technical field of air detection, in particular to an automatic opening device for a dust filter membrane clip. Background Art

[0002] In the process of air detection, it is necessary to detect the mass concentration of dust in the air or flue gas, so a dust concentration measuring instrument is needed. Its main principle is to send the dust into the mixing box through the dust generating device, and the dust is mixed in the mixing box to form a dust gas with relatively uniform concentration, and make the dust gas sample pass through the dust filter membrane clamp arranged inside the device. The filter membrane clamp clamps the filter membrane inside through the upper and lower clamps, and the filter membrane inside the filter membrane clamp intercepts the dust flowing through the air per unit time, and the dust concentration in the air is calculated by the amount of dust.

[0003] In order to ensure that the gas can only pass through the filter membrane during sampling, the upper and lower clamps of the filter membrane will clamp the filter membrane to ensure it is airtight. This makes it inconvenient to remove the membrane in actual operation. The upper and lower clamps need to be opened. However, if the force is too small, the membrane clamp cannot be opened. If the force is too large, the filter membrane will be shaken violently or the hand will come into contact with the dust collected by the filter membrane, which will directly render the filter membrane invalid and require re-sampling.

[0004] Therefore, the utility model provides a dust filter membrane clamp automatic opening device to meet the needs. Utility Model Content

[0024] The following is a detailed description of an automatic opening device for a dust filter membrane clamp provided by the utility model in conjunction with the accompanying drawings and specific embodiments; at the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are preferred embodiments, and for some known technologies, those skilled in the art may also adopt other alternative methods.

[0025] like Figures 1 to 3 As shown, an embodiment of the utility model provides an automatic opening device for a dust filter membrane clamp, comprising a main body 1, a rotating circle 2 is rotatably connected to the bottom end of the main body 1, a plurality of connecting sleeves 4 are fixedly connected to the bottom of the rotating circle 2, a rotating hole adapted to the connecting sleeve 4 is opened at the bottom of the main body 1, a placement pad is fixedly connected to the center of the bottom of the inner cavity of the main body 1, a filter membrane clamp body 7 is placed on the top of the placement pad, the number of clamping components 3 is five, which are annularly distributed on the inner side of the rotating circle 2, the number of connecting sleeves 4 is four, which are slidably connected to the outer side of the rotating hole, the bottom of the main body 1 is fixedly connected to a No. 1 motor 13, the output end of the No. 1 motor 13 is fixedly connected to a rotating seat 5, the outer side of the top of the rotating seat 5 is fixedly connected to a fixed block 6 adapted to the connecting sleeve 4, and the top of the fixed block 6 is fixedly connected to the corresponding connecting sleeve 4.

[0026] Place the dust filter membrane clamp body 7 on the placement pad inside the main body 1, start the No. 1 motor 13, drive the rotating seat 5 and the fixed block 6 to rotate, and drive the connecting sleeve 4 to rotate inside the rotating hole, so that the rotating circle 2 rotates.

[0027] like Figures 1 to 4As shown, the clamping assembly 3 is used to fix the filter membrane clamp body 7. The clamping assembly 3 is connected to the rotating circle 2. The clamping assembly 3 includes a rotating rod 301 rotatably connected to the inside of the rotating circle 2 and a sliding seat 303 fixedly connected to the bottom of the inner cavity of the main body 1. The end of the rotating rod 301 away from the rotating circle 2 is rotatably connected to a clamping block 302. The inner side of the clamping block 302 is designed as an arc. The bottom of the clamping block 302 is fixedly connected to a limiting rod, and the limiting rod is slidably connected to the inside of the sliding seat 303. The height of the sliding seat 303 is consistent with the placement pad.

[0028] The rotating ring 2 drives the rotating rod 301 to rotate, making it close to the sliding seat 303, and pushes the clamping block 302 to move synchronously inward under the limit of the sliding seat 303 to clamp the bottom end of the main filter membrane clamp body 7.

[0029] The inner side of the clamping block 302 adopts an arc-shaped design to contact the contour of the filter membrane clamp body 7 with the best fit. When the rotating circle 2 rotates, the rotating rod 301 acts as a bridge to evenly transmit the rotational power to each clamping block 302, thereby realizing a synchronous and stable clamping action. The sliding seat 303 provides a stable sliding track for the clamping block 302, ensuring the linearity and stability of the clamping block 302 during movement, ensuring that uniform pressure can be applied when clamping the filter membrane clamp body 7, and avoiding damage or displacement of the filter membrane clamp body 7 due to uneven force.

[0030] like Figures 1 to 5 As shown, both ends of one side of the main body 1 are fixedly connected with a No. 2 motor 8, the output end of the No. 2 motor 8 is fixedly connected with a screw rod 9, the other end of the screw rod 9 passes through the inner side of the main body 1, and the outer side of the screw rod 9 is threadedly connected with a moving seat 10, the moving seat 10 is located on the inner side of the main body 1, and the opposite sides of the two moving seats 10 are fixedly connected with separation plates 11, the separation plates 11 are in a shape that gradually becomes thicker from one side to the other side, the opposite sides of the two separation plates 11 are in close contact with the separation portion of the filter membrane clamp body 7, and moving holes 12 whose positions and shapes are adapted to the separation plates 11 are opened on both sides of the main body 1.

[0031] Then, the two No. 2 motors 8 are started synchronously to drive the screw rod 9 to rotate, so that the two shifting seats 10 drive the separation plates 11 to move on both sides of the filter membrane clamp body 7. The thinner side of the separation plate 11 cuts into the separation part of the filter membrane clamp body 7. With the gradual displacement of the separation plate 11, the upper half of the filter membrane clamp body 7 is separated, and the automatic opening is completed.

[0032] The shape of the separation plate 11 is designed to gradually increase in thickness from one side to the other side, so that when the separation plate 11 is pushed forward, it can gradually increase the pressure on the contact surface with the upper and lower parts of the filter membrane clamp body 7, thereby achieving a smooth and stable separation process. Compared with the traditional manual separation method, this progressive separation method is gentler, avoiding filter membrane shaking or dust falling due to sudden impact, and ensuring the integrity and accuracy of the dust sample collected in the filter membrane clamp body 7.

[0033] The working principle provided by the utility model is as follows: the dust filter membrane clamp body 7 is placed on the placement pad inside the main body 1, and the No. 1 motor 13 is started to drive the rotating seat 5 and the fixed block 6 to rotate, and the connecting sleeve 4 is driven to rotate inside the rotating hole, so that the rotating circle 2 rotates, and the rotating circle 2 drives the rotating rod 301 to rotate, so that it is close to the sliding seat 303, and pushes the clamping block 302 to move synchronously inward under the limit of the sliding seat 303, clamping the bottom end of the main filter membrane clamp body 7, and then the two No. 2 motors 8 are started synchronously to drive the screw rod 9 to rotate, so that the two moving seats 10 drive the separation plate 11 to move on both sides of the filter membrane clamp body 7, and the thinner side of the separation plate 11 cuts into the separation part of the filter membrane clamp body 7. With the gradual displacement of the separation plate 11, the upper half of the filter membrane clamp body 7 is separated, and the automatic opening is completed.
