Description

Technical Field

[0001] This utility model relates to the field of concentration detection technology, and in particular to a high-precision chemical liquid concentration detection device. Background Technology

[0002] Molar concentration, a commonly used method for expressing solution concentration, is calculated by dividing the amount of solute in the solution by the volume of the mixture. A prior patent (publication number: CN220819828U) discloses a reagent concentration detection device. This invention uses a lifting and rotating drive mechanism to uniformly stir the precipitated reagent solution in the detection tank before concentration detection, reducing localized concentration unevenness caused by reagent precipitation and ensuring the accuracy of the reagent concentration detection data. However, in practical applications, the solubility of chemical reagents is easily affected by environmental factors, and there may be cases where the chemical reagent does not completely dissolve during concentration detection, thus affecting the concentration detection results and leading to inaccurate results. Therefore, we propose a high-precision chemical liquid concentration detection device. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a high-precision chemical liquid concentration detection device.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A high-precision chemical liquid concentration detection device is designed, comprising a drive base disposed at one end of a substrate, the drive base including a servo motor, the servo motor being driven and connected to a detection cylinder, a heating jacket being disposed outside the detection cylinder, an annular plate being fixed at the top of the detection cylinder, a lifting plate being disposed above the annular plate and connected to a lifting mechanism, a sealing cover being fixed at the bottom of the lifting plate and fitting with the annular plate, a drive shaft being disposed inside the sealing cover and driven and connected to a servo motor, a stirring assembly being mounted on the drive shaft, and a concentration detector being mounted at the bottom of the drive shaft, a pressurizing mechanism being disposed on the lifting plate, the pressurizing mechanism including a pressurizing tube communicating with the detection cylinder.

[0006] In the above scheme, the drive base includes a mounting platform and a fixed base connected by screws. The servo motor is installed in the fixed base. The mounting platform is provided with a mounting groove. A positioning cylinder connected to the output shaft of the servo motor is installed in the mounting groove. The positioning cylinder is connected to the mounting platform through a bearing seat. The detection cylinder is engaged with the positioning cylinder.

[0007] In the above scheme, a positioning block is fixed on the outer wall of the detection cylinder, and a positioning groove that cooperates with the positioning block is opened on the inner wall of the positioning cylinder.

[0008] In the above scheme, the heating jacket is connected to the inner wall of the positioning cylinder.

[0009] In the above scheme, the lifting mechanism includes an assembly frame with a lead screw rotatably mounted inside. The bottom of the assembly frame is fixed to the base plate via a raised seat. A servo motor connected to the lead screw is installed inside the raised seat. A sliding block fixed to the lifting plate is threaded onto the lead screw. A distance sensor is installed at the bottom of the lifting plate.

[0010] In the above scheme, an air pump is installed on the lifting plate, the air pump's inflation end is connected to the pressurization pipe through an air delivery pipe, and a pressure sensor is installed inside the sealing cover.

[0011] In the above scheme, a temperature sensor that penetrates the sealing cover is installed on the lifting plate.

[0012] The advantages and beneficial effects of this utility model are as follows: By setting up a detection cylinder, a second servo motor, a drive shaft, and a stirring assembly, the second servo motor provides power to rotate the drive shaft, which in turn drives the stirring assembly to rotate inside the detection cylinder, thus fully stirring the solution inside the detection cylinder and preventing precipitation that could affect the detection results, thereby improving the accuracy of the detection. By setting up a heating jacket and a pressurizing mechanism, the heating jacket generates heat and conducts it into the detection cylinder, thereby increasing the solution temperature and improving the solubility of the solid solute. In conjunction with the pressurizing mechanism, a pressurizing pipe is used to pressurize the detection cylinder, further improving the solubility of the solid solute. Compared with the prior art, this method of improving the solubility of the solute through heating and pressurization prevents the solute from failing to dissolve completely and affecting the concentration detection results, further improving the accuracy of the detection results.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] Please see Figure 1-3 The present invention provides a technical solution: a high-precision chemical liquid concentration detection device, including a drive base 2 disposed at one end of a substrate 1, the drive base 2 including a servo motor 204, and the servo motor 204 being drivenly connected to a detection cylinder 3.

[0020] Furthermore, the drive base 2 includes a mounting platform 202 and a fixed base 201 connected by screws 203. The servo motor 204 is installed in the fixed base 201. The mounting platform 202 is provided with a mounting groove 207. A positioning cylinder 205 connected to the output shaft of the servo motor 204 is installed in the mounting groove 207. The positioning cylinder 205 is connected to the mounting platform 202 through a bearing seat 206. The bearing seat 206 is installed in the mounting platform 202. The positioning cylinder 205 is fitted with a bearing that is compatible with the bearing seat. The detection cylinder 3 is engaged with the positioning cylinder 205. By engaging, friction is generated between the detection cylinder 3 and the positioning cylinder 205, thereby causing the detection cylinder 3 to rotate under the drive of the positioning cylinder 205.

[0021] Furthermore, a positioning block 4 is fixed on the outer wall of the detection cylinder 3, and a positioning groove 209 that mates with the positioning block 4 is provided on the inner wall of the positioning cylinder 205. By using the positioning block 4 and the positioning groove 209, the detection cylinder 3 can be positioned quickly, and friction can be increased by increasing the contact area between the detection cylinder 3 and the positioning cylinder 205, thereby enabling the two to move synchronously.

[0022] The detection cylinder 3 is also equipped with a heating jacket 208; the heating jacket 208 is equipped with an electric heating wire, which generates heat after being connected to a power source.

[0023] Furthermore, the heating jacket 208 is connected to the inner wall of the positioning cylinder 205; the heating jacket 208 is set to avoid the positioning block 4 and the positioning groove 209 to prevent affecting the positioning connection between the detection cylinder 3 and the positioning cylinder 205.

[0024] Furthermore, a temperature sensor 15 is installed on the lifting plate 6, which penetrates the sealing cover 8. The temperature sensor 15 is used to detect the ambient temperature inside the detection cylinder 3, so as to regulate the temperature and thus control the solubility.

[0025] An annular plate 5 is fixed at the top of the detection cylinder 3, and a lifting plate 6 connected to the lifting mechanism is provided above the annular plate 5.

[0026] Furthermore, the lifting mechanism includes an assembly frame 17 with a lead screw 18 vertically rotatably mounted inside. The bottom of the assembly frame 17 is fixed to the base plate 1 via a raised seat 16. A servo motor 20, which is connected to the lead screw 18, is installed inside the raised seat 16. A mounting groove is provided at the top of the raised seat 16, and the servo motor 20 is installed in the mounting groove. A sliding block 19, which is fixed to the lifting plate 6, is threaded onto the lead screw 18. A distance sensor 22 is installed at the bottom of the lifting plate 6. The distance sensor 22 is used to detect the current height of the lifting plate 6. By starting the servo motor 20, the lead screw 18 is rotated, which causes the sliding block 19 to move up and down along the lead screw 18, thereby driving the lifting plate 6 to move up and down.

[0027] The bottom of the lifting plate 6 is fixed with a sealing cover 8 that fits with the annular plate 5. The sealing cover 8 and the annular plate 5 are sealed together. Inside the sealing cover 8, a drive shaft 9 that is connected to the servo motor 7 is rotatably installed. A stirring assembly 10 is installed on the drive shaft 9, and a concentration detector 21 is installed at the bottom of the drive shaft 9. The concentration detector 21 is used to detect the concentration of the solution. The lifting plate 6 drives the sealing cover 8 to move up and down, thereby causing the drive shaft 9, stirring assembly 10 and concentration detector 21 to disengage from the detection cylinder 3, so that the detection cylinder 3 can be taken out from the positioning cylinder 205.

[0028] Specifically, by setting up a detection cylinder 3, a second servo motor 7, a drive shaft 9, and a stirring assembly 10, the second servo motor 7 provides power to rotate the drive shaft 9 and drive the stirring assembly 10 to rotate inside the detection cylinder 3, which fully stirs the solution inside the detection cylinder 3, prevents the solution from precipitating and affecting the detection results, and improves the detection accuracy.

[0029] The lifting plate 6 is equipped with a pressurizing mechanism, which includes a pressurizing pipe 12 connected to the detection cylinder 3. The pressurizing pipe 12 is connected between the lifting plate 6 and the sealing cover 8.

[0030] Furthermore, an air pump 14 is installed on the lifting plate 6. The air pump 14 is connected to the pressurization pipe 12 through the air supply pipe 13. A pressure sensor 11 is installed inside the sealing cover 8. By starting the air pump 14, airflow is sent into the pressurization pipe 12 through the air supply pipe 13, and then airflow is introduced into the detection cylinder 3 to achieve the purpose of pressurization.

[0031] Specifically, by setting up a heating jacket 208 and a pressurizing mechanism, the heating jacket 208 generates heat and conducts it into the detection cylinder 3, thereby increasing the solution temperature and improving the solubility of the solid solute. In conjunction with the pressurizing mechanism, the pressurizing pipe 12 applies pressure to the detection cylinder 3 to further improve the solubility of the solid solute. Compared with the existing technology, the solubility of the solute is improved by heating and pressurizing, preventing the solute from failing to dissolve completely and affecting the concentration detection results, thus further improving the accuracy of the detection results.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
