Abstract
Description
Technical Field
[0001] This utility model relates to the field of plasma reaction equipment technology, specifically to an injection-type low-temperature plasma reaction device. Background Technology
[0002] Low-temperature plasma reaction refers to the use of an external voltage to ionize gas molecules, thereby forming low-temperature plasma. Low-temperature plasma degrades pollutants by using these high-energy electrons, free radicals and other active particles to interact with pollutants in the waste gas, causing the pollutant molecules to decompose in a very short time and undergo various subsequent reactions to achieve the purpose of degrading pollutants.
[0003] Currently, when using low-temperature plasma reaction equipment, materials are generally placed directly into the cavity's support or platform. The support or platform can obstruct the bottom of the product, and the area where the bottom of the product contacts the platform may not be able to effectively reach the plasma active particles due to physical contact or uneven electric field distribution, thus affecting the degradation quality. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide an injection-type low-temperature plasma reaction device, which can fully expose the bottom of the product by repeatedly replacing the raised plate, thereby solving the problem mentioned in the background art.

The end of the cavity away from the opening has a groove, and the electric slide is installed in the groove. The moving platform of the electric slide is fixedly connected to the vertical rod.
[0007] As a preferred technical solution, the positioning guide rail includes a fixed rod, a slide bar, a positioning block, and a compression spring. The fixed rods are all installed on the inner wall of the cavity, and each fixed rod has a slide groove on its inner side. The slide bars are all installed on both sides of the placement box and are slidably disposed in the slide groove. One end of each slide groove is open and the other end is sealed. Each slide groove opening has a positioning groove on its inner wall. One end of each positioning block is inserted into the positioning groove and is fixedly connected to the compression spring. The other end of each compression spring is installed on the inner wall of the positioning groove. The exposed end of each positioning block contacts the end face of the slide bar, and the other end of each slide bar abuts against the sealed end of the slide groove.

Detailed Implementation
[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an injection-type low-temperature plasma reaction device, comprising a low-temperature plasma reactor 1. The cavity of the low-temperature plasma reactor 1 contains multiple placement boxes 2, each with multiple strip-shaped openings on its bottom surface. Each strip-shaped opening contains a lifting plate 12, one end of which protrudes downwards to form an inclined guide portion 13. The guide portions 13 on the lifting plates 12 are staggered. Each placement box 2 has a push rod 15 on its bottom surface that pushes the lifting plate 12 upwards. A drive mechanism is installed at the end of the cavity away from the opening, synchronously moving the push rod 15. Positioning guide rails are installed between the two sides of the placement box 2 and the inner wall of the cavity. The low-temperature plasma reactor is an injection-type low-temperature plasma reaction device, capable of "injecting" plasma or active particles from the generation zone into the cavity to complete the degradation operation.
[0020] In this embodiment, the driving mechanism includes an electric slide table 11, a vertical rod 10, multiple insertion rods 16, multiple end plates 3, and guide blocks 4. The end plates 3 are all installed at both ends of the placement box 2, and each end plate 3 has a guide opening 9 in the middle. The guide blocks 4 are all installed at both ends of the push rod 15 and are slidably disposed in the guide opening 9. Each guide block 4 at the end away from the wall opening has a slot. The vertical rod 10 is vertically disposed inside the cavity. Each insertion rod 16 is installed on the vertical rod 10, and the other end of each insertion rod 16 is inserted into the corresponding slot. The end of the cavity away from the opening has a groove, and the electric slide table 11 is installed in the groove. The moving platform of the electric slide table 11 is fixedly connected to the vertical rod 10.
[0021] The groove has a wiring hole that connects to the outside. The wires on the electric slide extend to the outside through the wiring hole and are connected to a power supply and a microcontroller. The microcontroller can control the electric slide to move back and forth. After a certain period of time, the moving platform on the electric slide stops in the center, so that the plug can be smoothly inserted into the socket.
[0022] In this embodiment, the positioning guide rail includes a fixed rod 5, a slide bar 8, a positioning block 7, and a compression spring. The fixed rod 5 is installed on the inner wall of the cavity, and a slide groove 6 is provided on the inner side of the fixed rod 5. The slide bar 8 is installed on both sides of the placement box 2 and is slidably disposed in the slide groove 6. One end of the slide groove 6 is open and the other end is sealed. A positioning groove is provided on the inner wall of the opening of the slide groove 6. One end of the positioning block 7 is inserted into the positioning groove and is fixedly connected to the compression spring. The other end of the compression spring is installed on the inner wall of the positioning groove. The exposed end of the positioning block 7 is in contact with the end face of the slide bar 8, and the other end of the slide bar 8 is in contact with the sealed end of the slide groove 6.
[0023] In this embodiment, a shaft is installed on one end of the lifting plate 12 facing the guide section 13. A fixing seat 14 is provided on both sides of the guide section 13. One end of the fixing seat 14 is installed on the placement box 2. A shaft hole is provided on the fixing seat 14 opposite the shaft. Both ends of the shaft are inserted into the shaft hole.
[0024] In this embodiment, the end of the strip-shaped opening away from the guide portion 13 is enlarged to form a limiting groove, and the end of the lifting plate 12 protrudes to form a limiting portion 17. The limiting portion 17 is inserted into the limiting groove. The limiting portion and the limiting groove can limit the end of the lifting plate away from the guide portion, thus preventing downward rotation.
[0025] In this embodiment, the interior of the guide section 13 is hollow, which reduces the weight and materials used, and also reduces the weight of the lifting plate end, thus preventing the lifting plate from lifting itself.
[0026] In this embodiment, the four sides and bottom plate of the placement box 2 are covered with ventilation holes, which increases the exposure space of the bottom and sides, and can better complete the degradation operation.
[0027] When in use, press the positioning block inward. After the positioning block retracts into the positioning groove, the box can be pulled outward along the slide until it is taken out of the cavity, which makes it convenient to put in and take out the product.
[0028] After the product is placed in, the slide bar on the placement box can be inserted into the slide groove and move inward along the slide groove until the insertion rod is inserted into the insertion hole. The positioning block can be ejected outward by the rebound of the compression spring, and limit the slide bar and the placement box to prevent outward movement and thus avoid instability.
[0029] After the above is completed, the electric slide is activated, causing the moving platform of the electric slide to move back and forth. The movement of the moving platform drives the vertical rod and the insertion rod, and the movement of the insertion rod drives the guide block and the push rod. When the push rod moves to the left, it can squeeze the guide section on the left side, causing the corresponding lifting plate to rise upward around the shaft. The lifted lifting plate can expose the bottom of the product. After the push rod moves to the right, the previously lifted lifting plate can return to its original position, and the other set of guide sections will be squeezed by the push rod. The other set of lifting plates can lift the product again in another direction, so that the lifting plates continuously alternate to complete the lifting operation of the product, so that the bottom of the product can be fully exposed to ensure the subsequent degradation quality.
[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
