Description

Technical Field

[0001] This utility model relates to the field of backflush differential pressure level gauge technology, and in particular to a structure for quickly cleaning the pressure tap of a backflush differential pressure level gauge. Background Technology

[0002] The backflush differential pressure level gauge is a level detection instrument that combines backflush technology with differential pressure measurement principle. Its core is to isolate the medium from the measuring element by backflushing, and to use a differential pressure transmitter to detect the pressure change in the air blowing pipe, thereby indirectly reflecting the liquid level height.

[0003] As per announcement number CN209783694U, a differential pressure level transmitter belongs to the field of level transmitters. This utility model provides a differential pressure level transmitter comprising a differential pressure transmitter, an air blowing device, and an air inlet pipe. The air blowing device is connected to the air inlet pipe. The differential pressure transmitter is used to measure the differential pressure in the air inlet pipe. The differential pressure level transmitter also includes an outlet control rotor flowmeter, which is located between the air blowing device and the air inlet pipe and is used to stabilize the gas flow rate in the air inlet pipe. The outlet control rotor flowmeter includes an air inlet, an air outlet, a regulating valve, and a float. The air inlet is connected to the air blowing device, and the air outlet is connected to the air inlet pipe of the differential pressure level transmitter. The regulating valve is located at the air outlet. The float is located between the air inlet and the air outlet. This design avoids pressure changes in the reactor affecting pressure changes in the air inlet pipe, thereby improving the accuracy of the measured level value. Furthermore, this differential pressure level transmitter has a simple and compact structure, facilitating production and use.

[0004] This patent can improve the accuracy of liquid level measurement, but in actual use, the negative electrode air blowing tube and the negative electrode air blowing tube need to be cleaned regularly. The existing device does not have the function of quick disassembly and assembly of the air tube, which causes maintenance personnel to spend a lot of time disassembling the fixing screws, joints or seals, and even need to use special tools, which significantly extends the single maintenance cycle. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in practical use, the negative electrode air blowing tube and the negative electrode air blowing tube need to be cleaned regularly, and the existing device does not have a quick disassembly and assembly function for the air tube, which causes maintenance personnel to spend a lot of time disassembling the fixing screws, joints or seals, and even need to use special tools, significantly extending the single maintenance cycle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a structure for quickly cleaning the pressure tapping tube of a backflush differential pressure level gauge, comprising a level gauge body, a quick-release cleaning assembly connected to one side of the level gauge body, the quick-release cleaning assembly including a connector, a fixing block connected to one side of the connector, connecting blocks connected to both the upper and lower ends of the fixing block, two sets of springs arranged inside the connecting block, a base plate connected to the bottom of the two sets of springs, an insert block connected to the bottom of the base plate, a handle connected to the top of the base plate, a sealing ring fitted into the inner wall of the fixing block, a positive electrode air blowing tube inserted into the inside of the sealing ring, a locking block connected to the front end of the positive electrode air blowing tube, slots opened on both the upper and lower surfaces of the locking block, and a negative electrode air blowing tube arranged on the surface of the level gauge body near the positive electrode air blowing tube.

[0007] Furthermore, the outer surface of the card block is in contact with the fixing block, and the surface of the insertion block is provided with an oblique opening.

[0008] Furthermore, the position and size of the insert block match the position and size of the slot, and the insert block and the slot form a mating connection.

[0009] Furthermore, the handle is T-shaped, and the outer surface of the base plate fits against the inner wall of the connecting block.

[0010] Furthermore, the connecting block and the spring form an elastic structure.

[0011] Furthermore, a temperature control and heat dissipation assembly is provided on the other side of the liquid level gauge body. The temperature control and heat dissipation assembly includes a temperature control fan, and a frame is connected to the outer surface of the liquid level gauge body near the temperature control fan.

[0012] Furthermore, the frame has an internal mounting groove, the inner wall of the mounting groove is provided with a magnet, and the interior of the mounting groove is provided with a filter screen.

[0013] Furthermore, magnetic blocks are connected to both outer surfaces of the filter screen, a heat dissipation hole is provided on one side of the rear end of the liquid level gauge body, and an alarm and a temperature control fan are connected by an electric wire on the front surface of the liquid level gauge body.

[0015] Furthermore, the filter screen is slidably connected to the frame via a mounting groove, and a handle is connected to the top center of the filter screen.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, when it is necessary to disassemble and clean the positive or negative air tube, the handle can be pulled upwards simultaneously, so that the handle can pull the plug out of the slot. Then, the air tube can be pulled outwards to pull the locking block out of the fixing block, thereby completing the quick disassembly. At this time, the positive and negative air tubes can be cleaned. After cleaning, the locking block at the front end can be pushed directly into the fixing block and quickly fixed by the spring. This avoids the problem of having to spend a lot of time disassembling the fixing screws, connectors or seals every time the air tube is cleaned, and improves the convenience of cleaning.

[0018] 2. In this utility model, when the internal temperature of the level gauge body is high, the temperature control fan will automatically turn on to dissipate heat from the inside of the level gauge body. The filter screen installed on the outside can prevent dust from entering. When the temperature exceeds 85°C, the alarm will automatically sound to remind the operator to take action, so as to avoid the problem of high temperature causing damage to the level gauge body and thus affecting the accuracy of the test.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1, as Figure 1 - Figure 4 As shown, this utility model provides a structure for quickly cleaning the pressure tap of a backflush differential pressure level gauge, including a level gauge body 1. A quick-release cleaning assembly 2 is connected to one side of the level gauge body 1. The quick-release cleaning assembly 2 includes a connector 201, a fixing block 202 connected to one side of the connector 201, and connecting blocks 203 connected to both the upper and lower ends of the fixing block 202. Two sets of springs 204 are arranged inside the connecting block 203. A base plate 205 is connected to the bottom of the two sets of springs 204. An insert block 206 is connected to the bottom of the base plate 205, and a handle 207 is connected to the top of the base plate 205. A sealing ring 208 is fitted into the inner wall of the fixing block 202. The positive electrode air blowing tube 209 is inserted internally, and the front end of the positive electrode air blowing tube 209 is connected to the locking block 210. The upper and lower surfaces of the locking block 210 are provided with slots 211. The surface of the liquid level gauge body 1 near the positive electrode air blowing tube 209 is provided with a negative electrode air blowing tube 212. The outer surface of the locking block 210 is in contact with the fixing block 202. The surface of the insertion block 206 is provided with a bevel. The position and size of the insertion block 206 match the position and size of the slot 211. The insertion block 206 and the slot 211 form an insertion connection. The handle 207 is T-shaped. The outer surface of the base plate 205 is in contact with the inner wall of the connecting block 203. The connecting block 203 and the spring 204 form an elastic structure.

[0028] The effect achieved in Embodiment 1 is that when the positive electrode air blowing tube 209 needs to be disassembled and cleaned, both sets of handles 207 can be pulled up and down simultaneously, so that the handles 207 can drive the base plate 205 to press against the spring 204. This will cause the insert block 206 to be pulled out of the slot 211. Then, the positive electrode air blowing tube 209 can be pushed outward, so that the locking block 210 at the front end of the positive electrode air blowing tube 209 can be pulled out from the fixing block 202 to complete the disassembly. Then, the negative electrode air blowing tube 212 can be disassembled in the same way. At this time, the disassembled positive electrode air blowing tube 209 and negative electrode air blowing tube 212 can be cleaned. After cleaning, when it is necessary to reinstall, the locking block at the front end of the positive electrode air blowing tube 209 can be removed. Block 210 is pushed into the fixing block 202, which causes the positive air blowing tube 209 to be inserted into the sealing ring 208. At the same time, the locking block 210 also squeezes the oblique positions of the two sets of insert blocks 206. When the insert blocks 206 are compressed, they will automatically retract. When the locking block 210 is fully pushed into the fixing block 202, the spring 204 will push the base plate 205 through its own elasticity, causing the insert blocks 206 to be inserted into the slot 211 for fixation, thereby completing the quick installation of the positive air blowing tube 209. Then the negative air blowing tube 212 can be fixed. This avoids the problem of spending a lot of time disassembling the fixing screws, connectors or seals every time the air tube is cleaned, and improves the convenience of cleaning.

[0029] Example 2, as Figure 1 and Figure 5 As shown, a temperature control and heat dissipation assembly 3 is provided on the other side of the liquid level gauge body 1. The temperature control and heat dissipation assembly 3 includes a temperature control fan 301. A frame 302 is connected to the outer surface of the liquid level gauge body 1 near the temperature control fan 301. An installation groove 303 is opened inside the frame 302. A magnet 306 is provided on the inner wall of the installation groove 303. A filter screen 304 is provided inside the installation groove 303. Magnetic blocks 305 are connected to both outer surfaces of the filter screen 304. A heat dissipation hole 307 is provided on one side of the rear end of the liquid level gauge body 1. An alarm 308 is connected to the front end of the liquid level gauge body 1, and an electrical wire is connected between it and the temperature control fan 301. The position and size of the magnetic block 305 match the position and size of the magnet 306. A magnetic connection is formed between the magnetic block 305 and the magnet 306. The filter screen 304 is slidably connected to the frame 302 through the installation groove 303. A handle is connected to the top center of the filter screen 304.

[0030] The effect achieved in Embodiment 2 is that when the internal temperature of the level gauge body 1 exceeds 60°C after prolonged operation, the sensor in the temperature control fan 301 will automatically turn on the temperature control fan 301, allowing the temperature control fan 301 to dissipate heat through the heat dissipation hole 307. When the internal temperature exceeds 85°C, an electrical signal will be automatically sent to the alarm 308, causing the alarm 308 to sound automatically and reminding the operator to take emergency measures. The filter screen 304 can play a dustproof role, preventing dust from entering. When the filter screen 304 has accumulated a lot of dust, it can be directly pulled out and cleaned. After cleaning, the filter screen 304 can be directly pushed into the mounting slot 303 of the frame 302 and magnetically fixed by the magnetic connection between the magnetic block 305 and the magnet 306, avoiding the problem of high temperature causing damage to the level gauge body 1 and affecting the test accuracy.

[0031] Working principle: When it is necessary to disassemble and clean the positive electrode air tube 209 or the negative electrode air tube 212, the handle 207 can be pulled upwards simultaneously, so that the handle 207 can drive the insert 206 out of the slot 211. Then, pulling the air tube outwards will drive the locking block 210 out of the fixing block 202, thus completing the quick disassembly. At this time, the positive electrode air tube 209 and the negative electrode air tube 212 can be cleaned. After cleaning, the locking block 210 at the front end can be pushed directly into the fixing block 202, and the spring 204 will then advance the air tube. The system allows for quick and easy fixing, avoiding the need to spend a lot of time disassembling fixing screws, connectors, or seals every time the air pipe is cleaned, thus improving the convenience of cleaning. When the internal temperature of the level gauge body 1 is high, the temperature control fan 301 will automatically turn on to dissipate heat from the inside of the level gauge body 1. The filter screen 304 installed on the outside can prevent dust from entering. When the temperature exceeds 85°C, the alarm 308 will automatically sound to remind the operator to take action, thus preventing the level gauge body 1 from being damaged by high temperature and affecting the accuracy of the test.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
