Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a suction device for a cold filter plugging point tester. Background Art

[0002] The cold filter plugging point tester is an important instrument for measuring the fluidity of liquids at low temperatures. It is widely used in the petroleum and chemical industries, effectively evaluating the performance of oil products in low-temperature environments. However, existing cold filter plugging point testers have some shortcomings in the design of the suction device, mainly in terms of filtration efficiency and contamination protection.

[0003] Traditional measuring instruments typically use a single filter for liquid filtration. This design can result in insufficient retention of solid particles in the liquid, thus affecting the accuracy of measurement results. Furthermore, during the pumping process, due to direct contact between the pump and the external environment, impurities from the external air may enter the liquid barrel, causing liquid contamination and affecting subsequent recovery and use. Utility Model Content

[0004] The purpose of the utility model is to provide a suction device for a cold filter plugging point tester to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a suction device for a cold filter plugging point tester, comprising a base and a test tube, wherein a refrigeration device body is embedded and installed at the front end of the external top surface of the base, a test tube is inserted into the middle of the interior of the refrigeration device body, a sealing cover is provided at the top end of the test tube, a suction tube is inserted into the middle of the interior of the sealing cover, the top end of the suction tube is connected to a first pipe, one end of the first pipe is connected to one side of a first filter, the other side of the first filter is connected to one side of a second filter through a second pipe, and the other side of the second filter is connected to the input end of the pump body through a third pipe.

[0006] When using a cold filter point tester suction device in the present technical solution, the staff needs to first connect the external power supply to the utility model and control the operation of the utility model through the control panel. The staff pours the liquid to be tested into the interior of the test tube, and after pouring an appropriate amount, covers the top of the test tube with a cover. Then, the staff inserts the suction tube into the middle of the cover, inserts one end of the suction tube into the bottom end of the interior of the test tube, and then inserts the thermometer into one side of the cover, inserts one end of the suction tube into the bottom end of the interior of the test tube. After the thermometer is inserted, the staff uses a cable to connect to its top end, and then connects the first pipe to the top end of the suction tube. After completing the connection of the cable and the pipe, the staff controls the operation through the control panel. The cooling device body is running, and the temperature is reduced to the point where cold filter suction is required. After the temperature is reduced to this point, the staff starts the pump body, and the pump body generates negative pressure in the suction pipe. The suction pipe will draw the liquid in the test tube into it, and transport it to the inside of the first filter through the first pipe for filtration, filtering the solid particles contained in the liquid. The filtered liquid will be transported to the inside of the second filter through the second pipe. After secondary filtration by the second filter, the liquid will finally be transported to the inside of the pump body through the third pipe, and then transported to the inside of the barrel body by the pump body through the fourth pipe. When the barrel body is almost full of liquid, the staff turns to open the first inspection door, takes the barrel body out from the inside of the placement port and cleans it for subsequent use.

[0007] Preferably, the pump body is fixed to one end of the surface of the partition, and the partition is fixed to the middle of the top seat, and the top seat is arranged at the rear end of the outer top surface of the base. By providing the pump body, a negative pressure can be generated inside the suction tube, so that the liquid in the test tube is drawn into the inside, achieving the effect of negative pressure suction.

[0008] Preferably, the output end of the pump body is connected to a fourth conduit, one end of which is inserted into the interior of the barrel body. The barrel body is placed inside the placement port, and the placement port is opened in the middle of the surface of the partition. The installation of the fourth conduit allows the liquid pumped into the barrel body by the pump body to be transported to the interior of the barrel body through this pipe, and the opening of the placement port allows the barrel body to be placed inside, providing a stable placement position. The configuration of the barrel body allows the liquid transported into the interior of the barrel body by the pump body through the fourth conduit to be temporarily stored, facilitating later unified processing.

[0009] Preferably, a control panel is provided on the front surface of the top base, and a first inspection door is rotatably mounted on the rear surface of the top base. The provision of the control panel makes the operation of the utility model easier for staff to control, while the provision of the first inspection door forms a sealed space inside the top base, providing a location for maintenance and preventing external debris from intruding into the interior and contaminating the liquid stored in the barrel.

[0010] Preferably, a thermometer is inserted into one side of the inner portion of the cover, and the top end of the thermometer is connected to the rear surface of the control panel via a cable. By providing the thermometer, the temperature of the liquid in the test tube can be detected, achieving the effect of real-time temperature detection and transmitting the data to the control panel for staff to know.

[0011] Preferably, a second inspection door is rotatably mounted on the outer front surface of the base. The installation of the second inspection door allows staff to inspect and repair devices such as the refrigeration device body installed inside the base, providing a location for maintenance.

[0012] Preferably, the outer bottom surface of the base is provided with universal wheels, and there are four universal wheels, which are distributed in a rectangular shape. The installation of the four universal wheels makes the utility model easy to move and change the use position.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model significantly improves the filtration efficiency by setting two filters, effectively intercepts solid particles in the liquid, and ensures the accuracy of the measurement results. In addition, the liquid receiving barrel is located inside the top seat and is closed by an inspection door to prevent impurities in the external air from entering, avoiding liquid contamination. This design not only improves the reliability and durability of the equipment, but also improves the liquid recovery rate, promotes the application of cold filter plugging point testers in the petroleum and chemical industries, and provides higher protection for low-temperature performance evaluation in related industries.

[0024] The staff needs to first connect the external power supply of the utility model and control the operation of the utility model through the control panel 6. The staff pours the liquid to be tested into the inside of the test tube 15, and after pouring an appropriate amount, covers the top of the test tube 15 with the cover 3. Then the staff inserts the suction tube 13 into the middle of the cover 3, and inserts one end of it into the bottom end of the inside of the test tube 15. The staff then inserts the thermometer 4 into one side of the cover 3, and inserts one end of it into the bottom end of the inside of the test tube 15.
