Description

Technical Field

[0002] The chemical raw material detection device is a special equipment used to detect the physical properties, chemical composition, purity, impurity content and other indicators of chemical raw materials. Its core function is to operate through infrared detection. The specific directions involved include physical properties: such as the moisture content of raw materials (detected through the characteristic absorption of water molecules by infrared), density-related stacking characteristics (indirectly through weight and volume correlation); chemical composition: such as functional groups in organic matter (such as hydroxyl, carbonyl, etc.), and the content corresponding to the characteristic absorption peak of specific chemical components; purity and impurities: such as the characteristic peak intensity ratio of the main component (reflecting purity), and the characteristic absorption signal of impurities (such as water, specific residual solvents).

[0030] As can be seen from the above, by rotating the motor 306 to drive the first reciprocating screw 302 to rotate, the first gear 304 and the second gear 305 are engaged and connected, the two first reciprocating screws 302 can be rotated synchronously, and then the fixed plate 307 is driven to move on the limit rod 326 and the first reciprocating screw 302, so as to realize the movement of the inspection component 3 in the height horizontal direction, and the servo motor 312 drives the second reciprocating screw 313 to rotate, and the circular groove 318 and the guide groove 319 cooperate with the guide rod 314 to make the positioning block 317 move left and right inside the shell 310, thereby driving the discharge box 320 to move together, which is convenient for the discharge.

[0031] Example 2:

[0032] Please refer to Figure 4 and Figure 5 As shown, the feeding assembly 2 includes a charging box 201 and two connecting frames 202 fixedly connected to the top of the frame 1 and the top of the inner cavity. The bottom of the charging box 201 is sleeved with two groups of discharge pipes 203, and the discharge pipes 203 are three in a group. The outer ring of the discharge pipe 203 is provided with a solenoid valve 204. The bottom of the connecting frame 202 is provided with a T-shaped slot 205. The top of the connecting frame 202 is fixedly connected to an electric motor 206. The bottom of the output shaft of the electric motor 206 is fixedly connected to the third gear 207. The inner cavity of the T-shaped groove 205 is provided with a T-shaped plate 208, the bottom of the T-shaped plate 208 is fixedly connected with a material baffle plate 209, one side of the material baffle plate 209 is fixedly connected with a rack 210, the discharge pipe 203 is arranged on the same vertical horizontal line as the notch at the top of the discharge box 320, the rack 210 is meshed with the third gear 207, the material baffle plate 209 is slidably connected to the connecting frame 202 in the T-shaped groove 205 through the T-shaped plate 208, and the drying component 4 is arranged outside the frame 1.

[0033] As can be seen from the above, the loading box 201 in the feeding assembly 2 is used to store chemical raw materials, and the two groups of discharge pipes 203 (three in each group) can feed multiple discharge boxes 320 at the same time, thereby improving the feeding efficiency; the solenoid valve 204 on the discharge pipe 203 can accurately control whether the raw materials are fed or not, and the electric motor 206 drives the third gear 207 to rotate, and through the meshing connection with the rack 210, the baffle plate 209 slides in the T-slot 205 through the T-plate 208, thereby blocking or opening the discharge pipe 203, so that the start and stop of feeding can be controlled again, doubly ensuring the accuracy and controllability of feeding; the discharge pipe 203 and the top notch of the discharge box 320 are on the same vertical horizontal line, ensuring that the raw materials can be accurately put into the notch on the discharge box 320 and do not overflow.

[0034] Example 3:

[0035] Please refer to Figure 4 and Figure 6 As shown, the drying component 4 includes an air supply frame 401 fixedly connected to the left side of the frame body 1, and the inner wall of the air supply frame 401 is rotatably connected to three cross bars 402 through bearings, and the right side of one cross bar 402 is fixedly connected to a second bevel gear 403, and the left side of the cross bar 402 is each provided with a second sprocket 404, and the outside of the three second sprockets 404 is movably connected with a second chain 405, and the outer ring of the cross bar 402 is each provided with two fan blades 406, and the angles of the fan blades 406 are not set to the same, the second bevel gear 403 is meshed with the first bevel gear 322, and the air supply frame 401 is communicated with the air supply slot 102.

[0036] As can be seen from the above, when the first bevel gear 322 rotates, it drives one of the cross bars 402 to rotate through the meshing connection with the second bevel gear 403, and then with the help of the second sprocket 404 and the second chain 405, the three cross bars 402 rotate synchronously, and the fan blades 406 on the cross bars 402 rotate accordingly, generating airflow, which enters the interior of the frame 1 through the air supply frame 401 and the air supply slot 102 to dry the chemical raw materials temporarily stored in the frame 1 after detection. The different angles of the fan blades 406 can make the generated airflow more complex and enhance the drying effect.

[0037] Working principle: After the rotating motor 306 is started, it drives the first reciprocating screw 302 to rotate, and through the meshing of the first gear 304 and the second gear 305, the two first reciprocating screws 302 rotate synchronously. The fixed plate 307 is mounted on the first reciprocating screw 302 and the limit rod 326 through the circular hole 1 308 and the circular hole 2 309. As the first reciprocating screw 302 rotates, the fixed plate 307 moves horizontally up and down under the guidance of the limit rod 326, thereby driving the entire inspection component 3 to move horizontally in the frame 1 to adjust the distance with the feeding component 2. After the distance is adjusted, granular chemical raw materials are loaded into the charging box 201. The two groups of discharge pipes 203 (three in each group) correspond to different discharge boxes 320. When feeding is required, the electric motor 206 rotates forward to drive the third gear 207 to rotate, and through the meshing of the rack 210 and the third gear 207, the baffle plate 2 09 slides away in the T-slot 205 through the T-plate 208, and the raw material falls into the notch at the top of the discharge box 320 through the discharge pipe 203. When the discharge box 320 is almost full, the discharge pipe 203 can also be turned on and off under the control of the solenoid valve 204. After the feeding is completed, the electric motor 206 reverses, and the baffle plate 209 resets to block the discharge pipe 203, cooperating with the solenoid valve 204 to achieve double leakage prevention and precise control, and accurately feed the material to the discharge box 320. Then the servo motor 312 drives the second reciprocating screw 313 to rotate, and the positioning block 317 cooperates with the second reciprocating screw 313 and the guide rod 314 through the circular groove 318 and the guide groove 319 respectively, and the housing 310 is opened and closed. The two discharge boxes 320 have different initial positions and heights, which can realize alternating detection of "one up and one down". When one discharge box 320 is under the infrared detection device 101 for detection (the detection is the existing infrared detection technology, such as physical properties, chemical composition, purity, usually the detection time is instantaneous seconds or short-term tens of seconds response), then the other can synchronously perform loading or unloading operations to improve detection efficiency. After the detection, the electric push rod 324 pushes the sealing plate 325 to open the discharge port 321 to drop the chemical raw material into the frame 1, and the first bevel gear 322 rotates with the first reciprocating screw 302. The meshing of the second bevel gear 403 drives one of the cross bars 402 to rotate, and the three cross bars 402 are rotated synchronously through the second sprocket 404 and the second chain 405. The fan blades 406 on the cross bar 402 rotate accordingly to generate airflow. Due to the different angles of the fan blades 406, the airflow directions and speeds generated are different, forming a complex airflow field to enhance the drying effect. The airflow enters the frame 1 through the air supply frame 401 and the air supply slot 102, and dries the raw materials after inspection to ensure that the raw materials are in a dry state before discharge to avoid moisture affecting the subsequent use effect. Finally, the sealing plate 105 is slid open by the handle 106, and the chemical raw materials can be discharged through the discharge slot 103.
