Description

Technical Field

[0001] The utility model relates to the technical field of static electricity elimination equipment, in particular to chemical safety static electricity elimination equipment. Background Art

[0002] Static electricity discharge can instantly generate thousands or even tens of thousands of volts of voltage, which is enough to ignite or detonate the flammable gas or dust mixture in the chemical laboratory, causing a fire or explosion. Therefore, the chemical laboratory bench will be equipped with relevant static electricity elimination equipment, such as ion fans, anti-static work surfaces, anti-static wrist straps, etc., to ensure the safety of the experimental environment and the validity of the experimental data.

[0003] Among them, the ion blower is composed of a high-voltage power generator and a discharge electrode. It ionizes the air into a large number of positive and negative ions through pointed high-voltage corona discharge, and then uses wind to blow a large number of positive and negative ions to the surface of the object to neutralize static electricity, or directly places the static eliminator close to the surface of the object to neutralize static electricity.

[0004] Since the high-voltage electrode needle of the ion blower is exposed to the air, a high-voltage electric field will be generated. Therefore, dust will be absorbed on the electrode needle and the ion blower mesh cover, which requires regular cleaning and maintenance to restore the anti-static performance. The traditional ion blower mesh cover is generally fixed to the blower housing with multiple screws. When disassembling the mesh cover for maintenance, it is necessary to unscrew multiple screws, which is cumbersome and inconvenient to maintain. Utility Model Content

[0032] See also Figure 1-6 The utility model provides a technical solution: a chemical safety static elimination device, comprising an ion blower body 11, an air inlet or air outlet of the ion blower body 11 is installed with a mesh cover 13; a mounting ring 12 is fixedly connected to the ion blower body 11, and a locking assembly for fixing the mesh cover 13 is connected to the mounting ring 12; a rotating ring 21 is rotatably connected to the mounting ring 12, and a linkage assembly is connected to the rotating ring 21, and the linkage assembly drives the locking assembly to fix or unlock the mesh cover 13 through the rotation of the rotating ring 21.

[0033] In this solution: the chemical safety static elimination equipment uses an ion fan model AP-DC2453. The fan body 11 can eliminate static electricity in the chemical laboratory by connecting the power supply. The mounting ring 12 is fixedly connected to the air inlet or outlet of the ion fan body 11. Three protrusions are arranged circumferentially on the mesh cover 13. The mounting ring 12 is provided with grooves matching the protrusions. The mesh cover 13 is detachably connected to the mounting ring 12. The mounting ring 12 is provided with an annular groove, and the rotating ring 21 is sleeved in the annular groove of the mounting ring 12.

[0034] When installing the mesh cover 13, the three protrusions on the mesh cover 13 are aligned and pressed into the grooves of the mounting ring 12, and the locking assembly squeezes the protrusions of the mesh cover 13 to fix the mesh cover 13 on the mounting ring 12. The mesh cover 13 can be installed on the ion blower body 11 at one time. Compared with the method in the prior art where multiple screws need to be tightened when maintaining the mesh cover 13, the working efficiency of installing the mesh cover 13 is improved.

[0035] When removing the mesh cover 13, the rotating ring 21 is rotated to drive the locking assembly away from the protrusion of the mesh cover 13 to release the locking of the mesh cover 13 and the mounting ring 12. The three protrusions on the mesh cover 13 are taken out from the grooves of the mounting ring 12. The mesh cover 13 can be removed from the ion blower body 11 at one time. Compared with the method in the prior art that multiple screws need to be tightened when the mesh cover 13 is maintained, the working efficiency of removing the mesh cover 13 is improved.

[0036] In this embodiment: the mounting ring 12 is provided with a mounting ring stepped hole 121, and the mounting ring stepped hole 121 passes through the side wall of the mounting ring 12; the mesh cover 13 is provided with a mesh cover limiting hole 131, and the mesh cover limiting hole 131 and the mounting ring stepped hole 121 are located on the same axis; the locking assembly includes a stepped shaft 22 slidably connected to the mounting ring stepped hole 121, and a spring 23 is sleeved on the stepped shaft 22, and two ends of the spring 23 are respectively abutted against the end faces of the stepped shaft 22 and the end faces of the mounting ring stepped hole 121, and when the spring 23 is in a naturally expanded state, one end of the stepped shaft 22 is inserted into the mesh cover limiting hole 131.

[0037] In this solution: the mounting ring stepped hole 121 and the end with a larger diameter of the stepped shaft 22 are close to the mesh cover limiting hole 131 .

[0038] When installing the mesh cover 13, the rotating ring 21 is rotated to drive the stepped shaft 22 to completely retract into the mounting ring stepped hole 121, the three protrusions on the mesh cover 13 are aligned and pressed into the grooves of the mounting ring 12, the rotating ring 21 is stopped, and the stepped shaft 22 is inserted into the mesh cover limit hole 131 under the elastic force of the spring 23, so that the mesh cover 13 is locked on the mounting ring 12. The mesh cover 13 can be installed on the ion blower body 11 at one time.

[0039] When removing the screen 13, the rotating ring 21 is rotated to drive the stepped shaft 22 to completely retract into the mounting ring stepped hole 121, and the three protrusions on the screen 13 can be taken out from the grooves of the mounting ring 12. The screen 13 is removed from the ion blower body 11 at one time.

[0040] In this embodiment, the end of the stepped shaft 22 inserted into the mesh cover limiting hole 131 is hemispherical.

[0041] The stepped shaft 22 is inserted into the mesh cover limiting hole 131 and is set to be hemispherical at one end. When the protrusion of the mesh cover 13 is pressed into the groove of the mounting ring 12, the stepped shaft 22 is subjected to the pressure of the mesh cover 13 and generates an oblique force, so that the stepped shaft 22 can be completely withdrawn into the mounting ring step hole 121 without rotating the rotating ring 21. After the protrusion of the mesh cover 13 is pressed into the groove of the mounting ring 12, the stepped shaft 22 is inserted into the mesh cover limiting hole 131 under the elastic force of the spring 23, so that the mesh cover 13 is locked on the mounting ring 12. The mesh cover 13 can be installed on the ion blower body 11 at one time.

[0042] In this embodiment, the linkage assembly includes a pull rope 24 , which passes through the step hole 121 of the mounting ring, and has two ends fixedly connected to the step shaft 22 and the rotating ring 21 , respectively.

[0043] The step shaft 22 and the rotating ring 21 are connected by a pull rope 24. During the rotation of the rotating ring 21, the pull rope 24 extends along the inner wall of the rotating ring 21 and pulls the step shaft 22 out of the mesh cover limit hole 131, so that the mesh cover 13 can be removed from the ion blower body 11 at one time.

[0044] In this embodiment, a rotating ring groove 211 is formed on the rotating ring 21 . The rotating ring groove 211 extends circumferentially along the inner wall of the rotating ring 21 . During the rotation of the rotating ring 21 , the pull rope 24 extends into the rotating ring groove 211 .

[0045] By opening a rotating ring groove 211 on the rotating ring 21, the pull rope 24 extends along the rotating ring groove 211 during the clockwise rotation of the rotating ring 21, thereby preventing the pull rope 24 from being broken by friction between the inner wall of the rotating ring 21 and the outer wall of the mounting ring 12 during the rotation of the rotating ring 21, thereby extending the service life of the pull rope 24.

[0046] In this embodiment: a handle 25 is fixedly connected to the outer wall of the rotating ring 21 .

[0047] By arranging a handle 25 on the outer wall of the rotating ring 21, it is convenient to hold the handle 25 and rotate the rotating ring 21.

[0048] In this embodiment: the handle 25 is slidably connected with a sliding rod 26, and the ion blower body 11 is provided with a first limiting hole 111 and a second limiting hole 112; the sliding rod 26 is inserted into the first limiting hole 111 and the mesh cover 13 is in a locked state, and is inserted into the second limiting hole 112 and the mesh cover 13 is in an unlocked state.

[0049] The sliding rod 26 is inserted into the first limiting hole 111 to lock the mesh cover 13 to prevent the mesh cover 13 from being opened by mistake.

[0050] Insert the sliding rod 26 into the second limiting hole 112, the mesh cover 13 is in the unlocked state, and after the stepped shaft 22 exits the mesh cover limiting hole 131, during the process of removing the mesh cover 13 from the fan body 11, there is no need to hold the rotating ring 21 by hand to prevent the stepped shaft 22 from inserting into the mesh cover limiting hole 131.

[0051] In this embodiment, a spring sheet 14 is provided between the mounting ring 12 and the mesh cover 13 , one side of the spring sheet 14 is fixedly connected to the mounting ring 12 , and the mesh cover 13 is located outside the mounting ring 12 when the spring sheet 14 is in a natural state.

[0052] In this solution, the spring piece 14 is located in the groove of the mounting ring 12 , the mesh cover 13 is located outside the mounting ring 12 when the spring piece 14 is in a natural state, and the protrusion of the mesh cover 13 is located in the groove of the mounting ring 12 when the spring piece 14 is in a compressed state.

[0053] By arranging the spring piece 14 in the groove of the mounting ring 12, when the stepped shaft 22 exits the mesh cover limiting hole 131, the protrusion of the mesh cover 13 can exit the groove of the mounting ring 12 under the elastic force of the spring piece 14, so that the mesh cover 13 can be removed from the fan body 11.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
