Description

Technical Field

[0001] The utility model relates to the technical field of large-flow smoke and gas testers, in particular to a large-flow smoke and gas tester. Background Art

[0002] The smoke tester uses the constant potential electrolysis method to qualitatively and quantitatively measure harmful gases. It can be used by environmental protection, health, labor, safety supervision, military, scientific research, education and other departments to measure the emission concentration / total amount of smoke (gas) from various boilers and furnaces and the dust removal and desulfurization efficiency of equipment.

[0003] Existing smoke and dust testers generate heat when working, which is generally dissipated through heat dissipation holes. However, the efficiency of the heat dissipation holes is low, and dust can easily enter the box through the heat dissipation holes and cause damage to the tester. Therefore, it is necessary to optimize a large-flow smoke and dust gas tester through technological innovation and design optimization. Utility Model Content

[0004] Existing smoke and dust testers generate heat when working, and the heat is generally dissipated through the heat dissipation holes. However, the efficiency of the heat dissipation holes is low, and dust can easily enter the interior of the box through the heat dissipation holes and cause damage to the tester. In order to solve the above problems, the embodiment of the present application provides a large-flow smoke and dust gas tester. By setting a sealing mechanism, the ring and the filter plate can always fit tightly together, thereby improving the sealing of the ring and the filter plate and preventing dust from entering the interior of the box. At the same time, by setting a limiting mechanism, the filter plate can be quickly replaced, thereby improving the efficiency of replacing the filter plate.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0006] A large-flow smoke and gas tester, comprising:

[0007] protective shell;

[0008] Among them, the tester body is provided inside the protective shell, and a fixed block is fixed outside the protective shell. A filter plate is provided on the fixed block. A limiting mechanism for quickly disassembling and assembling the filter plate is provided on the fixed block. The fixed block is also provided with a sealing mechanism that can ensure the sealing between the filter plate and the fixed plate.

[0009] In a possible implementation, the protective shell includes a box body, a box cover is hingedly connected to the top of the box body, and a handle is fixed to the top of the box cover.

[0010] In a possible implementation, a heat dissipation port is provided on the box body, and an exhaust fan is installed inside the heat dissipation port, so that the exhaust fan accelerates the heat dissipation inside the box body.

[0011] In one possible implementation, several rubber plates are fixed inside the box, and there are gaps between the rubber plates. The rubber plates can reduce the collision between the box and the tester body. The gaps between the rubber plates facilitate the comprehensive heat dissipation inside the box in conjunction with the exhaust fan.

[0012] In one possible implementation, the sealing mechanism includes a circular opening on a fixed block, a circular ring is provided inside the circular opening, a fixing plate is fixed on the circular opening, a guide post is fixed on the fixing plate, a guide hole is provided on the circular ring, the guide post is inserted into the guide hole, a spring 2 is provided on the outside of the guide post between the circular ring and the fixing plate, and the filter plate is aligned with the circular ring and pressed, the circular ring will slide on the guide post, and the spring 2 is in a compressed state at this time, and will apply a force in the opposite direction to the circular ring, so that the circular ring and the filter plate fit tightly together, thereby improving the sealing between the circular ring and the filter plate and preventing dust from entering the box.

[0013] In one possible implementation, the limiting mechanism includes a rectangular block fixed on the fixed block, a limiting groove is provided on the rectangular block, a limiting block slides inside the limiting groove, a spring is provided in the limiting groove, and under the action of the spring, the limiting block will extend a part of the limiting groove to limit and fix the filter plate.

[0014] In a possible implementation, one end of the spring is fixedly connected to the limiting block, and the other end of the spring is fixedly connected to the rectangular block to prevent the limiting block from falling off.

[0015] In a possible implementation, the limit block is provided with an inclined surface at one end away from spring one, and the inclined surface faces the opposite direction of the circular ring. When the filter plate is aligned with the circular ring and pressed, the limit block is provided with an inclined surface. Under the pressure of the filter plate, it will enter the limit groove and squeeze spring one. When the filter plate is no longer squeezing the limit block, under the action of spring one, the limit block will extend out of a part of the limit groove to limit and fix the filter plate.

[0016] In a possible implementation, a filter plate is provided between the limiting block and the circular ring, and a stopper is provided on the fixing block to facilitate limiting the filter plate.

[0017] In summary, the present invention has at least one of the following beneficial technical effects:

[0018] 1. When the new filter plate is aligned with the circular ring and pressed, the limit block is set with an inclined surface. Under the pressure of the filter plate, it will enter the limit groove and squeeze the spring 1. When the filter plate is no longer squeezing the limit block, under the action of the spring 1, the limit block will extend a part of the limit groove to limit and fix the filter plate. Press the limit block, and after the limit block enters the limit groove, the circular ring will pop out the filter plate under the action of the spring 2, thereby completing the rapid replacement of the filter plate and improving the replacement efficiency.

[0019] 2. The ring is squeezed by the filter plate. At this time, spring 2 is in a compressed state, which will apply a force in the opposite direction to the ring, so that the ring and the filter plate fit tightly together, thereby improving the sealing between the ring and the filter plate and preventing dust from entering the box and causing damage to the tester.

[0034] When the exhaust fan 7 is turned on, several rubber plates 6 are fixed inside the box 1. There are gaps between the rubber plates 6. The rubber plates 6 can reduce the collision between the box 1 and the tester body 5. The gaps between the rubber plates 6 facilitate the exhaust fan 7 to fully dissipate heat inside the box 1.

[0035] When installing the filter plate 12, the sealing mechanism includes a circular opening 13 opened on the fixed block 4, a circular ring 8 is provided inside the circular opening 13, a fixing plate 11 is fixed on the circular opening 13, a guide column 17 is fixed on the fixing plate 11, a guide hole 18 is opened on the circular ring 8, the guide column 17 is inserted into the guide hole 18, and a spring 2 16 is sleeved on the outside of the guide column 17 between the circular ring 8 and the fixing plate 11. When the filter plate 12 is aligned with the circular ring 8 and pressed, the circular ring 8 will slide on the guide column 17. At this time, the spring 2 16 is in a compressed state and will apply a force in the opposite direction to the circular ring 8, so that the circular ring 8 and the filter plate 12 fit tightly together, thereby improving the sealing between the circular ring 8 and the filter plate 12 and preventing dust from entering the box body 1.

[0036] At the same time, the limiting mechanism includes a rectangular block 10 fixed on the fixed block 4, a limiting groove 14 is provided on the rectangular block 10, a limiting block 9 slides inside the limiting groove 14, and a spring 15 is provided in the limiting groove 14.

When the filter plate 12 is no longer squeezed by the limit block 9, the limit block 9 will extend out of the limit groove 14 to limit and fix the filter plate 12. At the same time, the ring 8 is also squeezed by the filter plate 12. At this time, the spring 16 is in a compressed state, which will apply a force in the opposite direction to the ring 8, so that the ring 8 and the filter plate 12 are tightly fitted together, thereby improving the sealing between the ring 8 and the filter plate 12 and preventing dust from entering the box 1.
