Description

Technical Field

[0001] The invention relates to the technical field of pipeline cleaning, in particular to a cleaning effect detection table for producing thermal oil cleaning agents. Background Art

[0002] After the thermal oil cleaning agent is produced, it is usually necessary to test the cleaning effect of the cleaning agent. Since the existing thermal oil transmission system usually uses metal pipes, it is impossible to directly observe the situation inside the pipe. In order to be able to directly observe the cleaning effect of the cleaning agent on the thermal oil, after using the cleaning agent to clean the inner wall of the pipe, it is usually necessary to use an endoscope or other device to reach into the inside of the pipe before directly observing the inner wall of the pipe. However, the price of existing endoscope equipment with high imaging quality is usually relatively expensive, and its subsequent maintenance cost is high, which leads to an increase in the cost of testing the cleaning effect of the cleaning agent. In addition, the use of endoscope equipment requires slowly controlling the probe to enter the inside of the pipe, resulting in a longer detection time and reduced detection efficiency. In addition, the conditions for using cleaning agents to clean pipes in the laboratory are relatively ideal, which does not fit the actual use scenario of the cleaning agent, resulting in inaccurate detection results. Summary of the Invention

[0025] Thermal oil is widely used in various industrial heating systems. The heated thermal oil is circulated and transmitted through the pipeline system to achieve heating of the designated parts. After the thermal oil circulates in the pipeline for a long time, it will deteriorate due to long-term high-temperature operation, frequent temperature fluctuations and oxidation. This will cause some sediment to form and adhere to the inside of the pipeline. The sediment adhered to the inside of the pipeline is likely to affect the heat transfer efficiency, and as the thickness of the sediment increases, it may even cause the pipeline to be blocked. For this reason, after the thermal oil heating system has been running for a period of time, it is usually necessary to discharge the thermal oil in the pipeline, and then inject the thermal oil cleaning agent into the pipeline and circulate the cleaning agent in the pipeline to clean the sediment attached to the inner wall of the pipeline. For this reason, the following is a detailed description of the detection process of the cleaning effect of the thermal oil cleaning agent: Since existing thermal oil transmission systems usually use metal pipes, it is impossible to directly observe the internal conditions of the pipes. In order to directly observe the cleaning effect of the cleaning agent on the thermal oil, after using the cleaning agent to clean the inner wall of the pipe, it is usually necessary to use an endoscope or other device to reach into the inside of the pipe before directly observing the inner wall of the pipe. However, the price of existing endoscope equipment with high imaging quality is usually relatively expensive, and its subsequent maintenance cost is high, which leads to an increase in the cost of testing the cleaning effect of the cleaning agent. In addition, the use of endoscope equipment requires slowly controlling the probe to enter the inside of the pipe, resulting in a longer detection time and reduced detection efficiency. In addition, the conditions for using cleaning agents to clean pipes in the laboratory are relatively ideal, which does not fit the actual use scenario of the cleaning agent, resulting in inaccurate detection results.

[0026] Before testing the cleaning effect of the thermal oil cleaning agent, first inject deteriorated thermal oil into the oil storage tank 201 so that the liquid level of the thermal oil in the oil storage tank 201 is higher than the oil outlet of the oil storage tank 201 but lower than the oil inlet of the oil storage tank 201, and control the first electric three-way valve 213 to connect the oil storage tank 201 with the pump 202, control the second electric three-way valve 214 to connect the oil storage tank 201 with the second communicating vessel 204, and then control the pump 202 to start forward suction work, so that the thermal oil is discharged from the liquid outlet of the oil storage tank 201, and then passes through the first electric three-way valve 213, the pump 202, the oil temperature regulator 206 and the first communicating vessel 203 in sequence, and then the thermal oil enters the three first detection tubes 3 respectively. It is explained here that the first detection tube 3 They are all half-tubes, and a complete sealed channel is formed between the mounting plate 2, the first detection tube 3 and the fixed plate 4. Then the heat-conducting oil passes through the first detection tube 3 and passes through the electric flow regulating valve 207 in turn and converges in the second communicating vessel 204, and finally flows back to the oil storage tank 201 through the second electric three-way valve 214 and the oil inlet of the oil storage tank 201. Since the heat-conducting oil injected is deteriorated, the heat-conducting oil contains more sediment. After the heat-conducting oil circulates in the first detection tube 3 for a period of time, a layer of sediment is easily attached to the inner wall of the first detection tube 3. At this time, the pump 202 is controlled to perform reverse suction, even if the heat-conducting oil in the second communicating vessel 204 passes through the electric flow regulating valve 207, the three first detection tubes 3, the first communicating vessel 203, the oil temperature regulator 2 06 and pump 202, and finally flows back to the oil outlet of the oil storage tank 201. Since the liquid level of the heat-conducting oil in the oil storage tank 201 is lower than the oil inlet of the oil storage tank 201, the heat-conducting oil in the oil storage tank 201 cannot enter the second communicating vessel 204 from the oil inlet. In this way, the heat-conducting oil in the three first detection tubes 3 and the connecting pipes can all be pumped back into the oil storage tank 201. Sediments are attached to the inner walls of the three first detection tubes 3. At this time, the conditions for detecting the cleaning effect of the heat-conducting oil cleaning agent are met. Then, the cleaning agent is tested. The first electric three-way valve 213 is controlled to connect the liquid outlet of the cleaning agent storage tank 205 with the pump 202, and the second electric three-way valve 214 is controlled to connect the liquid inlet of the cleaning agent storage tank 205 with the second communicating vessel 204. , and then inject the finished cleaning agent into the cleaning agent storage tank 205, so that the liquid level of the cleaning agent is higher than the liquid outlet of the cleaning agent storage tank 205, but lower than the liquid inlet of the cleaning agent storage tank 205, and then control the pump 202 to start forward suction, so that the cleaning agent passes through the liquid outlet of the cleaning agent storage tank 205, the first electric three-way valve 213, the pump 202, the oil temperature regulator 206, and the first communicating vessel 203 in sequence, and then the cleaning agent enters the three first detection tubes 3 respectively, and then the cleaning agent is gathered into the second communicating vessel 204 through the electric flow control valve 207, and finally flows back to the cleaning agent storage tank 205 through the second electric three-way valve 214 and the oil inlet of the cleaning agent storage tank 205. In this way, the forward suction is continuously performed by the pump 202,The cleaning agent is made to circulate in the three first detection tubes 3, so that the sediment attached to the inner wall of the first detection tube 3 is cleaned by the cleaning agent. When the cleaning agent has finished cleaning the inner wall of the first detection tube 3, the cleaning agent in the first detection tube 3 and its connected pipes is reversely sucked by the pump 202 in accordance with the principle of reverse suction of the heat transfer oil, so that all the cleaning agent flows back into the cleaning agent storage tank 205. Since the mounting plate 2 and the fixing plate 4 are both configured to be high-strength plastic plates made of transparent material, the inspector can stand in front of the fixing plate 4 and directly observe the condition of the inner wall of the first detection tube 3 through the fixing plate 4 and the mounting plate 2, which is different from the conventional method of using an endoscope to observe the inner wall of the pipeline. Since the first detection tube 3 is opaque The first detection tube 3 is made of metal, and the mounting plate 2 and the fixing plate 4 are both transparent. Therefore, the inspector can directly observe the condition of the inner wall of the first detection tube 3 through the transparent fixing plate 4 and the mounting plate 2. This eliminates the need for endoscope equipment for observation, reducing inspection costs. In addition, the inspector can directly observe all parts of the inner wall of the first detection tube 3, thereby improving inspection efficiency. In addition, by circulating the heat transfer oil in the first detection tube 3, the heat transfer oil forms a deposit inside the first detection tube 3, simulating the actual operation of the heat transfer oil in the pipeline system. Subsequently, the cleaning agent is circulated in the first detection tube 3, simulating the actual use of the cleaning agent. This ensures that the cleaning agent inspection scene is consistent with actual use and improves the accuracy of the cleaning effect inspection of the cleaning agent.

[0027] Since the heat transfer oil pipeline system is widely used, the heat transfer pipeline systems for different purposes have different parameters such as oil temperature, flow rate and oil pressure. The oil temperature and oil pressure of the heat transfer oil will affect the formation of its deposits. Therefore, in the process of simulating the actual operation of the heat transfer oil in the pipeline system, the temperature of the heat transfer oil flowing through the first detection tube 3 can be controlled by the oil temperature regulator 206, so as to simulate the formation of deposits in the first detection tube 3 of the heat transfer oil pipeline system under different oil temperature parameters. In this way, the cleaning agent can be used to clean the heat transfer oil pipeline system under different oil temperature parameters, so that the cleaning effect of the cleaning agent on the heat transfer oil pipeline system under different oil temperature parameters can be detected by the inspection personnel observing the condition of the inner wall of the first detection tube 3. On this basis, while ensuring that the electric flow control valve 207 is constant, the suction power of the pump 202 is controlled to adjust the flow rate of the heat transfer oil passing through the first detection tube 3. In this way, the formation of deposits in the thermal oil pipeline system under different flow rate parameters in the first detection tube 3 is simulated, so that the personnel can observe the condition of the inner wall of the first detection tube 3 to detect the cleaning effect of the cleaning agent on the thermal oil pipeline system under different flow rate parameters. Similarly, while ensuring that the suction power of the pump 202 is constant, the flow rate flowing through the inside of the first detection tube 3 is adjusted by controlling the electric flow control valve 207, thereby adjusting the oil pressure passing through the first detection tube 3. In this way, the formation of deposits in the thermal oil pipeline system under different oil pressure parameters in the first detection tube 3 is simulated, thereby facilitating the detection of the cleaning effect of the thermal oil pipeline system under different oil pressure parameters. In this way, compared with conventional cleaning and detection devices, by simulating different oil temperatures, flow rates and oil pressure parameters of the thermal oil pipeline system, the use scenarios of the cleaning agent are diversified, thereby detecting the cleaning effect of the cleaning agent in different usage scenarios.

[0028] On this basis, since there are inevitably bends in the thermal oil pipeline system, and the thermal oil flow rate distribution at the bends is uneven, which makes it easier for deposits to accumulate at the bends. Therefore, by setting a bend on the first detection tube 3, the situation of thermal oil passing through the bends in the thermal oil pipeline system is simulated, which makes it easier to detect the cleaning effect of the cleaning agent on the deposits at the bends. Moreover, by setting the pipe bending degree of the first detection tube 3 to be different, the situation of thermal oil passing through bends of different angles can be simulated at the same time, which makes it easier to detect the cleaning effect of the cleaning agent on the deposits at bends of different angles. Moreover, the cleaning effect of the cleaning agent on straight pipes and bends of different angles can be compared, making the cleaning effect of the cleaning agent more intuitive. On this basis, by setting the second detection tube 208 on the fixed plate 4, since the second detection tube 208 does not contact the thermal oil, the inner wall of the second detection tube 208 is clean, and the second detection tube 208 is used as a control for the cleaning effect of the deposits in the first detection tube 3, which facilitates the direct comparison and judgment of the cleaning effect by the detection personnel, thereby improving the detection efficiency.

[0029] Furthermore, since the pipeline layout of the heat transfer oil pipeline system is not the same, based on the horizontal plane, in addition to the vertical pipelines, there are also horizontal pipelines and inclined pipelines. When the heat transfer oil in the pipeline is in a stationary state, the distribution of sediments in pipelines arranged in different directions is different. For this reason, the motor 209 is controlled to drive the mounting plate 2 and the fixed plate 4 to rotate. Based on the view from right to left, all the first detection tubes 3 are driven counterclockwise by the fixed plate 4 until the first detection tube 3 is flush with the horizontal plane. In this way, the first detection tube 3 arranged in the vertical direction can be switched to the first detection tube 3 arranged in the horizontal direction, and the motor 209 can be used to drive the mounting plate 2 to rotate at any angle, so that the first detection tube 3 is in an inclined state at different angles, thereby simulating the distribution of sediments in pipelines with different inclined angles, so as to facilitate the detection of the cleaning effect of the cleaning agent on the sediments in pipelines with different inclined angles, so that the detection effect is more in line with actual usage.

[0030] The effectiveness test of conventional cleaning agents is usually to set the cleaning agent to clean the pipeline for a certain time, empty the cleaning agent in the pipeline, and then test the final cleaning effect of the cleaning agent. However, it is impossible to test the cleaning effect during the cleaning process. As a result, it is usually impossible to determine the final cleaning time required for the cleaning agent to completely clean the pipeline. This leads to inaccurate testing of the cleaning performance of the cleaning agent. For this purpose, a magnetic plate 211 is provided in the first detection tube 3, and the movable end of the baffle 212 is inclined toward the second communicating vessel 204. During the circulation of the cleaning agent in the first detection tube 3, the direction of the cleaning agent flow is from left to right, and the inclination direction of the movable end of the baffle 212 is consistent with the flow direction of the cleaning agent, so that Under the flushing, the baffle 212 is fitted with the magnetic plate 211, and the torsion spring between the baffle 212 and the magnetic plate 211 is compressed. The baffle 212 does not affect the flow of the cleaning agent. When the inner wall of the first detection tube 3 needs to be inspected during the cleaning process, the inspection personnel first manually move the magnetic block 210 to the right side of the part to be observed in the first detection tube 3, thereby driving the magnetic plate 211 to move to the right side of the part to be observed in the first detection tube 3 through the suction force between the magnetic block 210 and the magnetic plate 211, and controlling the pump 202 to reversely suck, so that the flow direction of the cleaning agent in the first detection tube 3 is changed from left to right to right. In this way, the flow direction of the cleaning agent is opposite to the inclination direction of the baffle 212. 1, the baffle 212 is separated from the magnetic plate 211, and the cleaning agent flows from right to left and the impact of the baffle 212 and the suction force on the left side of the baffle 212 are combined to rotate the baffle 212. The baffle 212 rotates counterclockwise when viewed from top to bottom until the edge of the baffle 212 fits the inner wall of the first detection tube 3. At this time, the baffle 212 blocks the first detection tube 3, and the cleaning agent on the right side of the baffle 212 cannot pass through the baffle 212. The cleaning agent on the left side of the baffle 212 continues to flow to the left under the reverse suction of the pump 202. In this way, the pipe on the left side of the baffle 212 is in a vacuum state, and the pump 202 is controlled to stop suction, so that the cleaning agent remains in a static state. At this time There is no cleaning agent in the left part of the baffle 212, that is, in the range of the part to be observed in the first detection tube 3, so that it is convenient for the inspector to observe whether the inner wall of the first detection tube 3 is clean. When the inspection is completed, it is only necessary to control the pump 202 to suck forward, so that the left side of the baffle 212 is refilled with cleaning agent, and the baffle 212 is pushed to rotate to fit with the magnetic plate 211. Compared with the conventional inspection device, there is no need to extract all the cleaning agent in the first detection tube 3. The inspector can control the pump 202 to suck backward at any time to expose a part of the inner wall of the first detection tube 3, so that the inspector can inspect the inner wall of the first detection tube 3 during the cleaning process. Then, the pump 202 is controlled to suck forward to resume the cleaning cycle.In this way, the cleaning effect can be conveniently tested during the cleaning process of the cleaning agent, so that the tester can determine the final cleaning time required for the cleaning agent to completely clean the pipeline, and the cleaning effect test of the cleaning agent can be more accurate. During this process, the tester can move the magnetic block 210 on the fixed plate 4, so that the magnetic plate 211 scrapes the front side of the fixed plate 4 along the bending direction of the first detection tube 3. In this way, the sediment attached to the front side of the fixed plate 4 can be scraped off, so that the tester can observe the inner wall of the first detection tube 3 more clearly. It is explained here that when the heat transfer oil and the cleaning agent are drained, the pump 202 starts to suck in the reverse direction, which makes it easy for the baffle 212 to block the first detection tube 3, so that there is heat transfer oil or cleaning agent remaining in the first detection tube 3. For this reason, before the heat transfer oil or cleaning agent is drained, the heat transfer The flow direction of the oil or cleaning agent is still from left to right, and the tilt direction of the movable end of the baffle 212 is consistent with the flow direction of the cleaning agent. Therefore, under the flushing of the heat transfer oil or cleaning agent, the baffle 212 is in a state of being in contact with the magnetic plate 211, and the torsion spring between the baffle 212 and the magnetic plate 211 is compressed. Then, the magnetic block 210 is manually slid to the rightmost side of the corresponding first detection tube 3, thereby driving the magnetic plate 211 and the baffle 212 to move to the rightmost side of the first detection tube 3, so that the magnetic plate 211 and the baffle 212 are stuck in the gap between the adjacent limit block 215 and the fixed plate 4, so that the baffle 212 is restricted from rotating by the limit block 215, thereby ensuring that during the operation of emptying the heat transfer oil or cleaning agent, the baffle 212 will not rotate to block the first detection tube 3, thereby ensuring that all the heat transfer oil or cleaning agent in the first detection tube 3 is completely drained.

[0031] Example 2 On the basis of Example 1, Figure 4-Figure 7 As shown, four grooves 4001 are provided on the fixing plate 4 ; the first detection tube 3 and the second detection tube 208 are both configured to be engaged with adjacent grooves 4001 ; and the fixing plate 4 is configured to be engaged with the mounting plate 2 .

[0032] It also includes a sealing strip 301 and an airbag 302; a sealing strip 301 is fixed in each groove 4001; an airbag 302 is fixed in each groove 4001; each sealing strip 301 is located on the inner side of the adjacent first detection tube 3; each airbag 302 is located on the outer side of the adjacent first detection tube 3; the airbag 302 is connected to an external air pump device.

[0033] It also includes a limiting plate 303 ; the limiting plate 303 is provided on the fixing platform 1 ; a limiting groove is opened on the limiting plate 303 that is consistent with the surface contour of the first detection tube 3 .

[0034] When the cleaning effect of the cleaning agent is detected, there is still some cleaning agent or sediment on the inner wall of the first detection tube 3, which will affect the accuracy of the next cleaning agent detection. To this end, all the first detection tubes 3 are set to engage with the groove 4001 on the fixing plate 4. When the cleaning agent detection is completed, the detachable interface on the pipeline between the electric flow control valve 207 and the adjacent first detection tube 3 is opened to release the connection between the electric flow control valve 207 and the adjacent first detection tube 3, and the detachable interface on the pipeline between the first communicating vessel 203 and the adjacent first detection tube 3 is opened to release the connection between the first communicating vessel 203 and the adjacent first detection tube 3. Then, the motor 209 is controlled to drive the mounting plate 2 and its connecting parts to rotate to a horizontal state, so that the first detection tube 3 falls into the corresponding limiting groove on the limiting plate 303. At this time, the fixing plate 4 is located on the upper side of the mounting plate 2, and the first detection tube 3 is located on the lower side of the mounting plate 2. Then, the fixing plate 4 can be pulled upward by the detection personnel to separate the fixing plate 4 from the mounting plate 2. Since the first detection tube 3 is The mounting plate 2 is blocked and cannot move upward, thereby disengaging the first detection tube 3 from the adjacent groove 4001, and then controlling the motor 209 to drive the mounting plate 2 to rotate to a vertical state. At this time, the first detection tube 3 is still located in the limiting groove on the limiting plate 303, and the fixing plate 4 and the first detection tube 3 can be quickly removed from the mounting plate 2, and then the first detection tube 3 and the fixing plate 4 that have been tested are taken away for subsequent cleaning so as to facilitate next use. At the same time, the inspection personnel can replace the new first detection tube 3 on the corresponding limiting groove on the limiting plate 303. The first detection tube 3 is inserted into the positioning groove, and then the mounting plate 2 is controlled to rotate to a horizontal state, so that the first detection tube 3 passes through the mounting plate 2, and then the new fixing plate 4 is pressed on the mounting plate 2, and the new first detection tube 3 is clamped in the groove 4001 on the new fixing plate 4, and then the connection between the first detection tube 3 and the adjacent electric flow regulating valve 207 and the first communicating vessel 203 is restored. In this way, the first detection tube 3 is limited by the limiting plate 303, and the auxiliary detection personnel will quickly replace the fixing plate 4 and the first detection tube 3, thereby improving the detection efficiency.

[0035] Furthermore, in order to ensure the sealing between the fixed plate 4 and the first detection tube 3 and prevent the heat transfer oil or cleaning agent from flowing out from the gap between the fixed plate 4 and the first detection tube 3 during the circulation process, when the first detection tube 3 is clamped in the corresponding groove 4001 on the fixed plate 4, the sealing strip 301 contacts the inner wall of the first detection tube 3, and at the same time the airbag 302 contacts the outer wall of the first detection tube 3, and then the external air pump device is controlled to inflate the airbag 302, so that the airbag 302 expands and squeezes the first detection tube 3, so that the first detection tube 3 is pressurized and in close contact with the sealing strip 301, thereby improving the sealing between the fixed plate 4 and the first detection tube 3 and ensuring the normal operation of the detection device.
