Description

Technical Field

[0001] This utility model relates to the technical field of static electricity elimination equipment, specifically a static electricity elimination device for chemical safety production. Background Technology

[0002] All technologies that use chemical methods to change the composition or structure of substances or synthesize new substances belong to chemical production technology, also known as chemical process, and the resulting products are called chemicals or chemical products. Static electricity is a static electric charge, or non-flowing electric charge. When electric charge accumulates on an object or surface, static electricity is formed. Electric charge is divided into two types: positive charge and negative charge. In other words, static electricity phenomena are also divided into two types: positive static electricity and negative static electricity. Static electricity is a very common phenomenon, but in the chemical production process, in order to ensure production safety, it is often necessary to eliminate static electricity near the production equipment. Nowadays, chemical plants use ion fans to eliminate static electricity. However, many chemical production equipment are large pieces of equipment, and ion fans alone cannot eliminate static electricity at high points on the equipment.

[0003] Existing technology, such as the patent with publication number CN216291545U, discloses a static electricity elimination device based on chemical safety. This device includes a main side plate, a base plate at the bottom of the main side plate, a fixed pulley on the bottom surface of the base plate, a motor on the top surface of the base plate, a support plate on the top of the base plate, an ion fan on the top surface of the support plate, a connecting shaft inside the main side plate, and a mounting block sleeved on the outer surface of the connecting shaft, which is connected to the support plate. This solution eliminates static electricity on the surface of chemical equipment by using an ion fan. The adjustable-height support plate at the top surface is used to perform comprehensive static elimination on equipment of different heights. It also features fixed pulleys, allowing the static elimination equipment to be rotated between different chemical equipment, avoiding the waste of resources that would otherwise require a separate static elimination device for each piece of equipment. However, during static elimination, simply fixing the pulleys with fixed plates is insufficient to ensure the equipment remains stable and stationary. Even slight shaking or displacement can alter the relative position of the ion fan and the chemical equipment, affecting the accuracy and effectiveness of static elimination.

[0004] To address the above problems, this utility model proposes a static electricity elimination device for chemical safety production. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing method of simply fixing the pulley with a fixed plate, which makes it difficult to ensure that the equipment remains stable and stationary during operation. This utility model proposes a static electricity elimination device for chemical safety production.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a static electricity elimination device for chemical safety production, including an ion fan and an angle adjustment frame shafted to the outer wall of the ion fan. Angle fixing components are fixedly connected to both sides of the angle adjustment frame, and a support base assembly is fixedly connected to the lower end of the angle adjustment frame. A pulley body is provided on the lower wall of the support base assembly. The support base assembly includes a support base body fixedly connected to the lower end of the angle adjustment frame. A motor is fixedly connected to the inner wall of the support base body. A first screw is fixedly connected to the output end of the motor, and a central connecting rod is fixedly connected to the end of the first screw away from the motor. The end of the connecting rod away from the first screw is fixedly connected to a second screw. The end of the second screw away from the connecting rod is rotatably connected to the inner wall of the support body. The outer wall of the first screw is threadedly connected to a first movable block, and the outer wall of the second screw is threadedly connected to a second movable block. The lower wall of the first movable block is axially connected to a first push plate, and the lower wall of the second movable block is axially connected to a second push plate. The lower ends of the first push plate and the second push plate are axially connected to a lower support block. The lower wall of the lower support block is fixedly connected to the pulley body, and the lower support block is slidably connected to the inner wall of the support body. The support body has an inverted concave structure, and the lower surface of the support body is flush with the ground.

[0007] Furthermore, the first screw and the second screw are symmetrically distributed about the center of the connecting rod, and the thread structures of the first screw and the second screw are opposite.

[0008] Furthermore, when the first movable block and the second movable block come closer together, the first push plate and the second push plate will drive the lower support block to move down, so that the pulley body is supported on the ground.

[0009] Furthermore, when the first movable block and the second movable block move away from each other, the first push plate and the second push plate will drive the lower support block to move upward, so that the pulley body is housed in the cavity of the support body, and the support body is supported on the ground.

[0010] Furthermore, the angle fixing assembly includes a movable channel formed in the side wall of the angle adjusting frame, and a fixing rod is threadedly connected to the inner wall of the movable channel.

[0011] Furthermore, a control block is fixedly connected to one end of the fixing rod.

[0012] Compared with the prior art, the beneficial effects of this utility model include: moving the device to the chemical equipment that needs static electricity elimination, and then restarting the motor to reverse it after reaching the designated position. This will cause the first and second movable blocks to move away from each other, and the first and second push plates will pull the lower support block upward. The pulley body will then be housed in the cavity of the support body, and the support body will directly contact the ground, increasing the contact area with the ground and providing stable support for the device. The support structure can be flexibly changed, allowing for flexible movement while ensuring that the equipment remains stable and stationary during operation, avoiding the impact of pulley shaking or displacement on the static electricity elimination effect.

[0019] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0020] Please see Figures 1-4 To address the issue that simply fixing the pulleys with fixed plates is insufficient to ensure the equipment remains stable and stationary during static elimination, and that even slight shaking or displacement can alter the relative position of the existing ion fan and chemical equipment, affecting the accuracy and effectiveness of static elimination, the following preferred technical solution is provided:

[0021] A static electricity elimination device for chemical safety production includes an ion fan 1, which is the core component of the entire device. Its working principle is to generate ions with positive and negative charges to neutralize the static charge accumulated on the surface of chemical equipment, thereby achieving static electricity elimination. An angle adjustment frame 2 is shaft-connected to the outer wall of the ion fan 1. Angle fixing components are fixedly connected to both sides of the angle adjustment frame 2. The angle adjustment frame 2 can rotate around the connecting shaft, allowing for flexible adjustment of the angle of the ion fan 1 according to the different positions and shapes of the chemical equipment. This enables the ionized air blown by the ion fan 1 to more precisely target the areas requiring static electricity elimination, improving the efficiency and comprehensiveness of static electricity elimination. A support base assembly 3 is fixedly connected to the lower end of the angle adjustment frame 2. The support base assembly 3 plays a crucial role in supporting the entire device and adjusting the device's contact with the ground. A pulley body 4 is provided on the lower wall of the support base assembly 3, facilitating the movement of the device between different chemical equipment and improving the device's operational flexibility.

[0022] The support base assembly 3 includes a support base body 31 fixedly connected to the lower end of the angle adjustment frame 2. The support base body 31 serves as the basic frame of the support base assembly 3, providing a position for the installation and fixation of other components. An electric motor 32 is fixedly connected to the inner wall of the support base body 31. The electric motor 32 serves as a power source, and outputs mechanical energy after it is started. The output end of the motor 32 is fixedly connected to the first screw 33. When the motor 32 rotates, it drives the first screw 33 to rotate synchronously. The end of the first screw 33 away from the motor 32 is fixedly connected to the intermediate connecting rod 34. The intermediate connecting rod 34 serves to connect the first screw 33 and the second screw 35, ensuring that they rotate synchronously. The end of the intermediate connecting rod 34 away from the first screw 33 is fixedly connected to the second screw 35. The end of the second screw 35 away from the intermediate connecting rod 34 is rotatably connected to the inner wall of the support body 31. Since the first screw 33 and the second screw 35 are symmetrically distributed about the center of the intermediate connecting rod 34 and have opposite thread structures, when the motor 32 drives the first screw 33 to rotate, according to the thread transmission principle, the first movable block 36 on the first screw 33 and the second movable block 37 on the second screw 35 will move in opposite directions or in opposite directions. The outer wall of the first screw 33 is threadedly connected to the first movable block 36, and the outer wall of the second screw 35 is threadedly connected to the second movable block 37. The movement state of the first movable block 36 and the second movable block 37 determines the change of the entire support structure. When the first movable block 36 and the second movable block 37 approach each other, the first push plate 38, which is connected to the lower wall shaft of the first movable block 36, and the second push plate 39, which is connected to the lower wall shaft of the second movable block 37, will move accordingly. Because the lower ends of the first push plate 38 and the second push plate 39 are connected to the lower support block 310, and the lower support block 310 is slidably connected to the inner wall of the support body 31, the first push plate 38 and the second push plate 39 will drive the lower support block 310 to move downward, so that the pulley body 4 is supported on the ground. At this time, the device is in a movable state, which is convenient for transfer. At different chemical equipment locations, when the first movable block 36 and the second movable block 37 move away from each other, the first push plate 38 and the second push plate 39 will drive the lower support block 310 to move upward, so that the pulley body 4 is housed in the cavity of the support base body 31. The support base body 31 is supported on the ground and has an inverted concave structure. The lower surface of the support base body 31 is flush with the ground. In this state, the contact area between the device and the ground increases, and the pulley body 4 no longer contacts the ground, thus avoiding the instability of the device caused by pulley shaking or displacement.

[0023] The angle fixing assembly includes a movable channel formed on the side wall of the angle adjustment frame 2. A fixing rod 5 is threadedly connected to the inner wall of the movable channel. A control block 6 is fixedly connected to one end of the fixing rod 5. After the angle adjustment frame 2 adjusts the angle of the ion fan 1, the fixing rod 5 is rotated in the movable channel by rotating the control block 6. After the fixing rod 5 extends a certain length outward from the angle adjustment frame 2, it can contact the surrounding objects and apply pressure, which further fixes the angle adjustment frame 2 and prevents the angle adjustment frame 2 from shifting due to external force or its own vibration during the static elimination process. This ensures that the ion fan 1 always performs static elimination work on the chemical equipment at the optimal angle.

[0024] Specifically, during the preparation phase, the motor 32 inside the support assembly 3 is started. The output shaft of the motor 32 rotates, driving the first screw 33 connected to it to rotate synchronously. Since the first screw 33 and the second screw 35 are connected by the central connecting rod 34 and are symmetrically distributed about the center of the central connecting rod 34, and their thread structures are opposite, the rotation of the first screw 33 will cause the second screw 35 to rotate in the same direction. During this process, the first movable block 36 on the first screw 33 and the second movable block 37 on the second screw 35 move closer to each other under the action of thread transmission, thereby driving the first push plate 38 and the second push plate 39 to move, pushing the lower support block 310 down, so that the pulley body 4 contacts the ground and supports the entire device. At this time, the operator can push the device, and with the help of the rolling of the pulley body 4, move the device to the location where electrostatic discharge needs to be performed. After reaching the designated position next to the chemical equipment, the motor 32 is restarted and reversed. This causes the first movable block 36 and the second movable block 37 to move away from each other. The first push plate 38 and the second push plate 39 pull the lower support block 310 upward, and the pulley body 4 is then housed in the cavity of the support body 31. The support body 31 is in direct contact with the ground, increasing the contact area with the ground and providing stable support for the device. This avoids the effect of static elimination caused by pulley shaking or displacement. The support structure can be flexibly changed, solving the problem that when performing static elimination work, it is difficult to ensure that the equipment remains stable and stationary during operation by simply fixing the pulley with a fixed plate. Even slight shaking or displacement may cause the relative position of the existing ion fan and chemical equipment to change, affecting the accuracy and effect of static elimination.

[0025] Subsequently, based on the specific shape of the chemical equipment and the location of static electricity distribution, the operator manually rotates the angle adjustment frame 2 to adjust the angle of the ion fan 1, ensuring that the ion fan 1 blows ionizing air at the optimal angle to the parts of the chemical equipment where static electricity needs to be eliminated. After the angle adjustment is completed, the fixed rods 5 in the movable channels on both sides of the angle adjustment frame 2 are rotated. The control block 6 operates the fixed rods 5 to rotate threadedly within the movable channels, causing them to extend outwards and contact suitable surrounding fixed structures. The friction and pressure between the fixed rods 5 and the surrounding structures further secure the angle adjustment frame 2, preventing angular deviation during operation.

[0026] Once everything is ready, ion fan 1 is turned on. The internal working mechanism of ion fan 1 generates ions with positive and negative charges. These ions are rapidly diffused into the surrounding space by the air blown out by the fan, and neutralize the static charge accumulated on the surface of the chemical equipment, gradually eliminating the static electricity on the surface of the equipment. Throughout the static elimination process, the device, with its stable support structure and precise angle adjustment, ensures that ion fan 1 continuously and efficiently eliminates static electricity from the chemical equipment, ensuring a safe environment for chemical production.
