[0002] Explosion-proof areas are set up in the chemical industry: The chemical industry often involves the processing, production or storage of flammable substances such as flammable gases, vapors, liquids or dust. These substances may cause explosions under certain conditions (such as sufficient oxygen, fire sources, etc.). Therefore, explosion-proof areas are set up. In explosion-proof areas, the control of static electricity is particularly strict. In terms of actuators, pneumatic actuators should be preferred instead of electric actuators. If electrical appliances are used, they must meet explosion-proof requirements.

[0003] In pharmaceutical and chemical production, concentration analyzers (refractometers) can be used to measure the concentration of dissolved substances in liquids, help regulate production processes, and ensure that products meet quality standards and specified concentration requirements. For example, in mixing and formula control, concentration analyzers can be used to detect the concentration of different ingredients during the mixing process to ensure that the formula and proportion of the mixture meet the expected requirements and avoid quality fluctuations. It can also be used for mixing and formula control, wastewater treatment and environmental monitoring, raw material quality control, and pipeline monitoring. These applications show the diversity and importance of online concentration analyzers in the chemical industry. They help improve production efficiency, product quality, and play a key role in environmental protection and safety.

[0004] However, the concentration analyzer has a detection part composed of an optical sensor. The measurement results of the concentration analyzer may be affected by the surface dirt on the optical window of the detection part. For example, surface dirt may change the refraction or transmission characteristics of light on the sensor surface, thereby interfering with the light path.

[0037] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] See also Figure 1-9 The present invention discloses a concentration analyzer cleaning device, method and installation structure suitable for explosion-proof areas, which can be used for cleaning concentration analyzers 507 in explosion-proof areas.

[0039] In a first aspect, the present invention discloses a concentration analyzer cleaning device suitable for explosion-proof areas, providing a device for solving the surface cleaning problem of the detection part 508 of the concentration analyzer 507 , mainly for targeted cleaning of the window part of the detection part 508 .

[0040] In the present disclosure, Figure 1-4 As shown, the concentration analyzer cleaning device suitable for explosion-proof areas includes a mounting seat 100 , a mounting shaft 200 , a brush head 300 and a driving device 400 .

[0041] The mounting seat 100 is provided with a flange portion 101, one side of the flange portion 101 is provided with a raised mounting body 110, a chamber 113 is provided in the mounting body 110, the opening of the chamber 113 penetrates the flange portion 101, and the bottom of the chamber 113 is provided with an extension hole 114 extending toward the side away from the flange portion 101 and penetrating the mounting body 110; wherein the extension hole 114 provides installation and support for the mounting shaft 200, ensuring that the brush head 300 remains stable under the impact of the high-speed flow of the solution without abnormal shaking. The chamber 113 provides a space for setting the connection structure between the movable part of the driving device 400 and the mounting shaft 200.

[0042] The mounting shaft 200 is disposed in the extension hole 114, such as Figure 2 , one end extends into the chamber 113, and the other end extends out of the extension hole 114, a sealing structure is arranged between the installation shaft 200 and the inner wall of the extension hole 114; generally, the sealing structure comprises a sealing ring 115 arranged in the extension hole 114, the outer side of the sealing ring 115 is sealed with the extension hole 114, and the inner side is sealed with the installation shaft 200, wherein the number of the sealing ring 115 can be one or more. Figure 2 and Figure 3 An annular groove 117 is provided at one end of the extension hole 114 away from the chamber 113, and then the outer peripheral side of the sealing ring 115 is embedded in the annular groove 117, so that the sealing structure can work stably. To ensure the sealing effect, two annular grooves 117 are provided to correspondingly provide a high-strength sealing structure with two sealing rings 115. Under the action of the sealing structure, the solution cannot penetrate the sealing structure into the chamber 113, and further leakage cannot occur.

[0043] Among them, the brush head 300 is detachably arranged at one end of the installation shaft 200 away from the chamber 113, and the brush head 300 has an action part 301 for cleaning; the detachable connection between the brush head 300 and the installation shaft 200 facilitates subsequent maintenance, such as replacement of the action part 301 after excessive wear.

[0044] Among them, the driving device 400 is arranged at the opening of the chamber 113 and connected to the flange part 101, and the movable part of the driving device 400 extends to the chamber 113 and is connected to the installation shaft 200; the movement of the movable part of the driving device 400 can drive the installation shaft 200 to rotate, and the rotation of the installation shaft 200 can drive the brush head 300 to swing.

[0045] With the support of the above structural design, the concentration analyzer cleaning device suitable for explosion-proof areas of the present invention can be set on the opposite side of the concentration analyzer 507 used for detecting the concentration of solutes in the solution and other application environments, and is used to clean the detection part 508 of the concentration analyzer 507.

[0046] The concentration analyzer cleaning device suitable for explosion-proof areas uses the active part of the driving device 400 to drive the brush head 300 to swing, so as to use the action part 301 to clean the detection part 508 of the concentration analyzer 507 in a brushing manner. Since the surface of the detection part 508 is immersed in the solution to be detected, the substances in the solution will adhere to and accumulate on the surface of the detection part 508 to form dirt, but the action part 301 contacts the surface of the detection part 508 and repeatedly brushes the surface of the detection part 508, such as circular rotation or reciprocating swing brushing similar to the wiper of a car, to achieve efficient cleaning of the detection part 508. Generally, the solution to be detected is in a flowing state, and the action part 301 can play a certain stirring role in addition to brushing, which promotes the dirt on the surface of the detection part 508 to leave the surface of the action part 301, further ensuring the cleaning effect.

[0047] The flange portion 101 is used for installation and connection when the concentration analyzer cleaning device suitable for explosion-proof areas is used.

[0048] The movement of the brush head 300 is controlled by a driving device 400, which is a pneumatic actuator. It avoids the use of electric drive, prevents the occurrence of static electricity, and ensures explosion-proof safety capabilities.

[0049] In some embodiments, the installation shaft 200 is provided in the chamber 113 with a limiting step (not marked in the drawings, from Figure 2 As can be seen, the limiting step here can prevent the installation shaft 200 from transitioning toward the concentration analyzer 507 when the active part 301 is excessively worn, causing the non-active part 301 of the brush head 300 to partially contact the outer surface of the detection part 508, resulting in scratches on the outer surface of the contact detection part 508.

[0050] In some embodiments, a mounting platform 120 structure is provided in the chamber 113, and a needle bearing 116 is provided on the mounting platform 120 to support the mounting shaft 200. This allows the mounting shaft 200 to remain stable in an active state. The needle bearing 116 can also be used to support the movement of the mounting shaft 200, thereby preventing unnecessary wear between the mounting shaft 200 and the inner surface of the extension hole 114.

[0051] In the disclosed embodiment, the driving device 400 is a rotary swing cylinder or a pneumatic motor, wherein the pneumatic motor can support the installation shaft 200 to cyclically rotate, and the rotary swing driving device 400 can support the installation shaft 200 to reciprocately swing or rotate at a certain angle.

[0052] In some embodiments, the driving device 400 is preferably a rotation swing driving device 400. Because the rotation swing driving device 400 has initial positions in two directions, we refer to Figure 7 and Figure 8The working state of the driving device 400 can be used to position the swinging brush head 300. When the brush head 300 is not working, the brush head 300 can avoid the optical window light-transmitting working area of ​​the detection unit 508, thereby avoiding the brush head 300 affecting the operation of the concentration analyzer 507.

[0053] In some embodiments, if the application scenario does not have high requirements for explosion-proof level, the driving device 400 may adopt a motor or a motor with certain explosion-proof standards, or other driving structures that can achieve the same purpose.

[0054] In the present disclosure, Figure 4 As shown, the brush head 300 includes a pressing plate 302 , one end of which is connected to the end of the mounting shaft 200 via a screw 600 , and a scraper serving as an action portion 301 is disposed on the pressing plate 302 .

[0055] In some embodiments, in order to facilitate the installation and stable connection, two pressure plates 302 are provided, and the two pressure plates 302 clamp the scraper (active part 301) in the middle, one of the pressure plates 302 is provided with a threaded hole four 303, and the other pressure plate 302 is provided with a through hole three 304 opposite to the threaded hole four 303, and then the screw 600 can be used to pass through the through hole three 304 and the scraper and cooperate with the threaded hole four 303 to achieve installation and fixation.

[0056] It is worth noting that the understanding of the scraper blade should not be limited to a sheet-like object, but can also be a brush blade, or other device structure that can contact the surface of an object and actively wipe the stains on the surface of the object.

[0057] Regarding the connection between the brush head 300 and the mounting shaft 200, a through hole can be set at the end of the mounting shaft 200, and a support platform can be set on the lower side of the through hole. The support platform is supported on the lower side of the pressure plate 302 to limit the up and down shaking of the pressure plate 302. Then, a screw 600 can be set to pass through the end of one pressure plate 302, the through hole of the mounting shaft 200, and then be threadedly connected to the other pressure plate 302 to achieve detachable installation.

[0058] In the embodiment of the present disclosure, the mounting body 110 includes a cylinder 111 and a cylinder 2 112 connected in sequence, the cylinder 111 is connected to the flange portion 101, the axial diameter of the cylinder 2 112 is smaller than the axial diameter of the cylinder 111, the cylinder 2 112 is not coaxial with the cylinder 111, and the extension hole 114 is coaxial with the cylinder 2 112; wherein, Figure 1 and Figure 2, cylinder two 112 is tangent to the outer circumference of cylinder one 111, and the distance between the axes of cylinder two 112 and cylinder one 111 is preferably larger than the maximum range diameter of the optical window of the detection part 508; one end of the brush head 300 is connected to the mounting shaft 200, and the other end extends in a direction away from the plane where the axes of cylinder one 111 and cylinder two 112 are located; the swing range of the brush head 300 passes through the area where the axis of cylinder one 111 is located, and the swing angle is preferably greater than 180 degrees.

[0059] According to Figure 7 and Figure 8 In the application installation method, we usually let the cylinder 111 and the detection part 508 face each other (if the detection part 508 is circular, they are coaxial), so that the installation shaft 200 will naturally lean to one side of the optical window of the detection part 508, and the rotation or reciprocating swing of the installation shaft 200 can play the effect of swinging and brushing the detection part 508. The brushing amplitude is large, which can not only play a role in ensuring the cleaning effect, but also can place the position of the installation shaft 200 to interfere with the light-transmitting working area of ​​the detection part 508 (the installation shaft 200 and the optical window of the detection part 508 are not directly facing each other).

[0060] Among them, the cylinder 111 can be used Figure 6 It is worth noting that the outer diameter of the second cylinder 112 is smaller than the outer diameter of the first cylinder 111. The smaller outer diameter of the second cylinder 112 reduces the space occupied in the solution. The design of the shape features and the smaller space occupied reduce the impact of the protruding structure of the second cylinder 112 on the flow of the solution.

[0061] In the embodiment of the present disclosure, the side of the flange 101 connected to the mounting body 110 is provided with a raised portion 102 that continuously surrounds the mounting body 110, and the side of the raised portion 102 facing the mounting body 110 continuously surrounds the recessed portion 103 of the mounting body 110. Figure 7 The recess 103 is used to set the sealing ring 104 during the installation application of the present invention, and then used for sealing cooperation.

[0062] In the disclosed embodiment, the movable part includes a driving shaft 401 extending into the chamber; an elastic device is provided between the driving shaft 401 and the mounting shaft, and the elastic device drives the driving shaft 401 to maintain a tendency to move away from the driving shaft 401 .

[0063] In some embodiments, the elastic device includes a spring, and the movable portion includes a driving shaft 401 (such as the driving shaft 401 of the rotation drive device 400) that can be driven to rotate by air pressure, and the driving shaft 401 extends toward the chamber 113; Figure 2As shown, in the chamber 113, a latch 402 is provided on one end of the driving shaft 401 or the mounting shaft 200, and a U-shaped opening groove 403 is provided on the other end, and at least one of the ends of the driving shaft 401 or the mounting shaft 200 has an extension section 404; a hollow sleeve 405 is provided, a U-shaped opening groove 406 is provided at one end of the sleeve 405, a latch 407 is provided on the inner side of the other end, and a spring 408 is provided in the sleeve 405; the latch 407 is inserted into the U-shaped opening groove 403, the latch 402 is inserted into the U-shaped opening groove 406, and the spring 408 is supported between the latch 402 and the latch 407.

[0064] Combination Figure 2 and Figure 3 Generally, the latch 1 402 is arranged on the driving shaft 401 of the driving device 400, and then the driving shaft 401 extends in the direction close to the latch 1 402 to form an extension section 404. A U-shaped opening groove 1 403 is arranged on the end of the installation shaft 200 located in the chamber 113, and a latch 2 407 arranged on the shaft sleeve 405 is movably embedded in the U-shaped opening groove 1 403, and the U-shaped opening groove 2 406 is forked on the latch 1 402. The inner holes at both ends of the shaft sleeve 405 are respectively sleeved on the extension section 404 and the end of the installation shaft 200. Under the support of the spring 408, the installation shaft 200 has a tendency to move toward the concentration analyzer 507. If the action part 301 is worn during operation, it will be compensated under the support of the spring 408. At the same time, the spring 408 gives the action part 301 an appropriate pressure on the surface of the detection part 508 to ensure the cleaning effect.

[0065] In some embodiments, Fig. 9 As shown, the elastic device includes a spring 408, and the movable part includes a driving shaft 401, which extends into the chamber; in the chamber, a latch 402 is vertically penetrated at the end of the driving shaft 401, and a section of the end of the driving shaft 401 near the latch 402 in the direction of the brush head is an extension section 404; a sleeve 405 extending in the direction of the driving shaft 401 is coaxially arranged at the end of the mounting shaft in the chamber, and a U-shaped opening groove 403 is arranged at the end of the sleeve 405; the extension section 404 is inserted into the sleeve 405, and the latch 402 is embedded in the U-shaped opening groove 403, a spring 408 is arranged in the sleeve 405, and the spring 408 is supported between the driving shaft 401 and the extension section 404.

The auxiliary plate 106 is preferably made of stainless steel, firstly, to avoid setting a threaded hole 109 on a non-metallic material for mounting the driving device 400; secondly, the auxiliary plate 106 can support the large end of the screw 600 during the installation and application of the present invention, thereby reducing the wear of the large end of the screw 600 on the non-metallic flange portion 101, which may cause unstable installation after long-term maintenance.
