Description

Technical Field

[0001] The invention belongs to the technical field of dynamic adsorption, and in particular relates to a dynamic adsorption carbon monoxide vapor test bench. Background Art

[0002] With the development of industry and the improvement of environmental protection requirements, the monitoring and treatment of harmful gases have become particularly important. Carbon monoxide, as a colorless and odorless toxic gas, is widely present in many scenarios such as industrial production. Its leakage is often difficult to detect and poses a threat to human health. At present, the outdoor adsorption treatment of carbon monoxide requires materials with a high adsorption rate. Selecting materials with strong adsorption capacity is conducive to the treatment of carbon monoxide. By comparing the concentration of carbon monoxide before and after adsorption, the adsorption rate of carbon monoxide on the material test piece can be calculated, which is convenient for selecting materials with better adsorption rate.

[0003] The Chinese patent with the authorization announcement number CN217725072U discloses a fixed bed reaction device suitable for dynamic adsorption test of carbon dioxide, which is equipped with a heating furnace and heat preservation measures to heat the gas throughout the process to avoid the gas not reaching the set desorption and adsorption temperature when contacting the sample in the fixed bed reactor due to too short heating time; a gas buffer tank is provided to reduce the effect of excessive gas pressure on CO 2 The impact of manual valve III can prevent the mixed gas in the pipeline from rushing into the fixed bed reactor due to unstable air flow at the moment when the valve is opened, thus causing experimental measurement errors.

[0004] However, this technical solution still has at least the following defects: if the technical solution is used to test carbon monoxide, due to the toxicity of carbon monoxide, a strict sealing effect needs to be maintained, so when performing batch testing, the test pieces cannot enter the reaction device without carbon monoxide leakage, and when testing multiple test pieces, the device needs to be vented, which reduces efficiency, and the device needs frequent manual control, which is cumbersome to operate. In view of this, the present invention is proposed. Summary of the invention

The tested test pieces are classified and managed by providing a discharging mechanism to facilitate later classification management.

[0088] The mobile test unit includes a test judgment strategy, which includes obtaining a lateral instruction or a longitudinal instruction generated by a concentration detection strategy, and executing a test program according to the lateral instruction or the longitudinal instruction;

[0089] When receiving a horizontal instruction, the test judgment strategy generates a null signal, and ignores the test program based on the null signal. When receiving a vertical instruction, the test judgment strategy generates an execution signal, and executes the test program based on the execution signal, so as to control the test mechanism to execute the test work based on the test program.

[0090] The test procedure includes moving the electric slider 201 to the support plate 209, controlling the driving device 202 to lower the plug plate 204 so that the plug plate 204 clamps the test piece, and controlling the electric slider 201 to move and reset after the plug plate 204 is lowered, so as to drive the test piece to move to the connector 208 to complete the test sampling. After the electric slider 201 is reset, the electric cylinder 207 controls the connector 208 to move and connect the test piece, and the exhaust gas treatment device 215 generates suction to make the test piece absorb carbon monoxide. After the test is completed, the electric slider 201 is moved to the support plate 209 again, and the plug plate 204 is raised during the movement. When the test program obtains the first test instruction or the middle test instruction, the above process is repeated. When the final test instruction is obtained, the process ends.

[0091] The mobile test unit also includes a result calculation strategy, which includes obtaining a test carbon monoxide concentration in the manifold 211 monitored by the first sensor 212, and calculating an adsorption rate of the test piece based on the test carbon monoxide concentration and the real-time carbon monoxide concentration;

[0092] The result calculation strategy also includes a standard adsorption rate. When the adsorption rate of the test piece is greater than or equal to the standard adsorption rate, the adsorption rate of the test piece meets the standard, so as to characterize the test piece as a good product and generate a good product instruction. When the adsorption rate of the test piece is less than the standard adsorption rate, the adsorption rate of the test piece does not meet the standard, so as to characterize the test piece as a defective product and generate a defective product instruction.

[0093] The discharge module includes a classification management strategy, which includes obtaining instructions generated by the result calculation strategy, and controlling the driving element 112 to drive the baffle 113 according to the instructions. When a good product instruction is obtained, the driving element 112 drives the baffle 113 to a horizontal state to indicate that the good product chamber 109 is connected to the test box 100. When a defective product instruction is obtained, the driving element 112 drives the baffle 113 to a vertical state to indicate that the defective chamber 110 is connected to the test box 100.

[0094] The implementation principle of the dynamic adsorption carbon monoxide vapor test bench of this embodiment is as follows: when working, a plurality of test pieces to be tested are placed in the material storage plate 104, and the cylinder 102 is started. The test piece at the bottom is driven to move by the cylinder 102 and the push plate 103, and is made to enter the rectangular groove inside the rotating column 107. At the same time, the cylinder 102 abuts against the test piece and pushes the sealing plug 108 to move until the arc of one side of the sealing plug 108 fits with the rotating column 107. At this time, the power device 106 drives the rotating column 107 to rotate 180 degrees. During the rotation process, the sealing plug 108 is sealed and connected with the rotating column 107 and the adapter 105 and the side wall of the test box 100, so that the gas inside the test box 100 cannot flow out;

[0095] After the cylinder 102 is rotated, it pushes the test piece, and moves the test piece inside to the support plate 209 through the sealing plug 108, and the carbon monoxide enters the test box 100 through the nozzle 219 through the carbon monoxide supplier 218, and is mixed by the fan 217 to simulate air. At the same time, the power source 213 drives the baffle 214 to block the bottom of the manifold 211, so that the inside of the test box 100 is connected to the exhaust gas treatment device 215 through the branch pipe 220 and the manifold 211 to balance the pressure generated when adding carbon monoxide. When the carbon monoxide concentration in the test box 100 reaches a certain level, the power source 213 drives the baffle 214 to block the branch pipe 220;

[0096] The driving device 202 is moved to the top of the test piece by the electric slide rail 200 and the electric slider 201. The driving device 202 rotates the drive gear 203 to lower the plug plate 204, thereby clamping the two sides of the test piece. The electric slider 201 moves and resets, and drives the test piece to move to the connector 208 through the plug plate 204. At this time, the electric cylinder 207 drives the connector 208 to move and clamp the two ends of the test piece. The exhaust gas treatment device 215 generates suction force, which is transmitted to the test piece through the manifold 211 and the conduit 210, so that the test piece absorbs the carbon monoxide gas inside. By comparing the monitoring values ​​of the first sensor 212 and the second sensor 216, the absorption rate of the test piece to carbon monoxide can be obtained;

[0097] After the test is completed, the connector 208 is separated from the test piece by the electric cylinder 207, and the electric slider 201 drives the plug plate 204 to move, and the plug plate 204 drives the tested test piece to move. When it moves to the inclined surface of the fixed plate 206, the test piece moves along the inclined surface to the bottom of the support plate 209, and continues to enter the collection box 101 along the inclined surface. The driving element 112 is controlled according to the test result of the test piece, so that the blocking rod 113 is rotated to the appropriate position, so that the test piece can enter the good product chamber 109 or the defective product chamber 110.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
