The test chamber body is provided with a test chamber. Air inlet plates and return air plates are respectively arranged on both side walls of the test chamber. A plurality of ventilation holes for ventilation and pressure relief are arranged on both the air inlet plate and the return air plate. A ventilation duct is arranged at the top of the test chamber. The ventilation duct and the test chamber form an air flow cycle. An evaporator, a heater and at least one air supply device are arranged inside the ventilation duct; it has the following advantages: 1. An air flow cycle is formed between the test chamber and the ventilation duct, and horizontal air blows inside the test chamber, and the test samples are evenly affected by temperature; 2. The equipment structure is simple and the manufacturing cost is low; 3. The ventilation holes have multiple functions.

Cooperating with the pressure relief device, rapid pressure relief inside the test chamber is achieved, and an explosion-proof effect is achieved. The safety and stability of the equipment are high.

[0004] However, the air supply device used in the above high and low temperature explosion-proof test chamber is usually a blower, and ordinary blowers usually do not have a special explosion-proof function, which poses a safety hazard. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an explosion-proof air-blowing system, which solves the problem that the air supply device used in the high and low temperature explosion-proof test chamber is usually a blower, and ordinary blowers usually do not have a special explosion-proof function, which poses a safety hazard.

[0006] To achieve the above purpose, the utility model provides an explosion-proof air-blowing system, which includes a box body, a mounting plate and a partition. The mounting plate is fixedly connected to the box body and is located inside the box body.

Specific implementation mode

[0018] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0019] The first embodiment of this application is:

[0020] Please refer to Figures 1 to 3 , wherein, Figure 1 is a schematic structural diagram inside the box body 101 of the first embodiment of the present invention. Figure 2 is a schematic structural diagram of the air exchange component of the first embodiment of the present invention. Figure 3 is a schematic cross-sectional structural diagram of the air exchange component of the first embodiment of the present invention. The present invention provides an explosion-proof air blowing system, including a box body 101, a mounting plate 102, a partition board 103 and an air exchange component. The air exchange component includes a volute 104, an air guiding ring 105, an air blade 106, an explosion-proof motor 107 and an air guiding member. The air guiding member includes a first air duct 108, a second air duct 109, a third air duct 110, a valve 111, a plurality of air outlet ducts 112 and a plurality of isolation boards 113.

[0021] For this specific implementation mode, the mounting plate 102 is fixedly connected to the box body 101 and is located inside the box body 101. The partition board 103 is fixedly connected to the box body 101 and is perpendicularly distributed to the mounting plate 102. The box body 101 is the box body 101 disclosed in the publication number CN118501393A, and its explosion-proof detection principle is used for testing. This is the prior art and will not be elaborated too much. Among them, the partition board 103 divides the internal space of the box body 101 to facilitate the detection test.

[0022] Among them, the volute 104 is detachably connected to the mounting plate 102 and is located on one side of the mounting plate 102. The air guiding ring 105 is located inside the volute 104. The impeller 106 is fixedly connected to the air guiding ring 105 and is located inside the volute 104. The output end of the explosion-proof motor 107 is connected to the air guiding ring 105, and the air guiding member is connected to the volute 104. The explosion-proof motor 107 drives the air guiding ring 105 to rotate, thereby driving the impeller 106 to rotate. The impeller 106 is made of stainless steel, and the volute 104 and the air guiding ring 105 are made of copper. Due to the inconsistent hardness of the materials, sparks are prevented from being generated during accidental collisions. Moreover, the impeller 106 is far from the volute 104 and will not rub against the volute 104 during operation, so sparks are not easily generated, making the safety performance stronger. The air guiding member plays a role in guiding the air flow.

[0023] Secondly, the first air duct 108 is fixedly connected to the volute 104 and is communicated with the inside of the volute 104; the second air duct 109 is communicated with the first air duct 108 and penetrates through the partition plate 103. The first air duct 108 guides the air generated by the rotation of the impeller 106 into the second air duct 109, and the second air duct 109 penetrates through the partition plate 103, which can guide the air flow to the rear of the partition plate 103.

[0024] At the same time, the third air duct 110 is communicated with the second air duct 109 and is located on the side of the partition plate 103 away from the first air duct 108; the valve 111 is located inside the third air duct 110. The third air duct 110 receives the air flow introduced by the second air duct 109 and discharges it to the rear of the partition plate 103. The valve 111 is rotatably arranged inside the third air duct 110 and is driven to rotate by the driving device above, so as to close and open the second air duct 109, thereby realizing the control of the air flow and facilitating the detection and test.

[0025] In addition, a plurality of air outlet pipes 112 are respectively communicated with the third air duct 110 and are respectively located on the side of the third air duct 110 away from the partition plate 103. The plurality of air outlet pipes 112 discharge the air flow, so that the air flow can be dispersed and discharged, facilitating its diffusion.

[0026] Finally, a plurality of partition plates 113 are respectively fixedly connected to the second air duct 109 and are respectively located inside the second air duct 109. The plurality of partition plates 113 divide the inside of the second air duct 109 into a plurality of channels, so that the air flow can be dispersed and discharged, making the air circulation effect better.

[0027] Using an explosion-proof air-blowing system according to this embodiment to conduct a detection test inside the box body 101, when air flow is required, open the valve 111, and at the same time start the explosion-proof motor 107 to drive the air guide ring 105 and the fan blade 106 to rotate, draw in the air in front of the partition plate 103, and introduce the air to the rear of the partition plate 103 through the first air duct 108, the second air duct 109 and the third air duct 110 to form a cycle for the detection test. Among them, the fan blade 106 is made of stainless steel, and the volute 104 and the air guide ring 105 are made of copper. Due to the inconsistent hardness of the materials, sparks are prevented from being generated during accidental collisions, and the fan blade 106 is far away from the volute 104 and will not rub against the volute 104 during operation, so sparks are not easily generated, which makes the safety stronger.

[0028] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
