Description

Technical Field

[0001] This utility model relates to the field of test tube cleaning technology, and in particular to a hydrocarbon test tube cleaning device. Background Technology

[0002] Hydrocarbons are placed in test tubes and tested using a liquid petroleum product hydrocarbon analyzer. After the test is completed, the test tubes are cleaned using a cleaning device to prepare them for subsequent tests.

[0003] Currently, existing hydrocarbon test tubes are cleaned by directly rinsing them, resulting in the loss of hydrocarbon substances during the cleaning process and causing waste. Therefore, in order to better realize the hydrocarbon test tube cleaning function, promote technological progress in the industry, and improve the core technology competitiveness, this application proposes a new implementation scheme for hydrocarbon test tube cleaning devices that is different from the existing technology. Utility Model Content

[0004] The purpose of this invention is to solve the problem of hydrocarbon substances being lost and wasted during the cleaning process of existing test tubes, and to propose a hydrocarbon test tube cleaning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hydrocarbon test tube cleaning device includes a connecting assembly. The connecting assembly includes a connecting shell, an air inlet pipe and an air outlet pipe sealed to the top of the connecting shell, and first control valves threaded to the top ends of both the air inlet and the air outlet pipes. One of the first control valves is threaded to the top end of a first gas pipe, and the other first control valve is threaded to the top end of a waste tank connector. A water inlet pipe is sealed to one side of the connecting shell, and a water outlet pipe is sealed to the other side of the connecting shell. A second control valve is threaded to one end of both the water inlet and the water outlet pipes. The other end of one of the second control valves is threaded to a water inlet pump connector, and the other end of the other second control valve is threaded to a water outlet pump connector.

[0007] Furthermore, a steel wire is bonded to one side of the inner wall of the air intake pipe, with the bottom end of the steel wire protruding out of the air intake pipe.

[0008] Furthermore, a perforated plate is snapped between the inner circumferential walls of the connecting shell, through which the water inlet pipe and the connecting hose pass.

[0009] Furthermore, a sealing cylinder is bonded to the bottom end of the connecting shell, and a clamp is fitted around the outer circumference of the sealing cylinder.

[0010] Furthermore, the sealing cylinder is a silicone cylinder.

[0011] Furthermore, a second air pipe is threaded to one end of the first air pipe, and a compressed air tank connector is threaded to the other end of the second air pipe.

[0012] Furthermore, a connecting hose is sealed and inserted into one end of the water outlet pipe.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Gas is introduced into the hydrocarbon test tube through the second gas pipe, the first gas pipe, and the inlet pipe in the compressed gas tank, thereby blowing up the hydrocarbon substances in the test tube. Then, under the flow of gas, the hydrocarbon substances flow into the outlet pipe, and then flow into the waste gas tank for centralized collection through the first control valve and the waste tank connector, thereby avoiding waste.

[0015] 2. By blowing air, the steel wire is made to strike the inner wall of the hydrocarbon test tube, thereby knocking off the hydrocarbon substances adhering to the inner wall of the test tube, so as to fully collect the hydrocarbon substances in the test tube and improve the collection efficiency.

[0016] 3. Water is pumped into the inlet pipe by the inlet pump and then into the hydrocarbon test tube. Then, the water in the hydrocarbon test tube is pumped into the connecting hose by the outlet pump and then discharged into the collection box from the outlet pipe. This process cleans the hydrocarbon test tube and is simple, convenient and quick. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A hydrocarbon test tube cleaning device includes a connecting assembly 1, which includes a connecting shell 101. An air inlet pipe 102 and an air outlet pipe 103 are sealed and inserted into the top of the connecting shell 101. The top ends of the air inlet pipe 102 and the air outlet pipe 103 are threadedly connected to a first control valve 104. The top end of one of the first control valves 104 is threadedly connected to a first gas pipe 105. One end of the first gas pipe 105 is threadedly connected to a second gas pipe 6. The other end of the second gas pipe 6 is threadedly connected to a compressed gas tank connector 7. The top end of the other first control valve 104 is threadedly connected to a waste tank connector 106. The gas in the compressed gas tank is input into the hydrocarbon test tube through the second gas pipe 6, the first gas pipe 105, and the air inlet pipe 102, thereby blowing up the hydrocarbon substances in the test tube. Then, under the flow of the gas flow, the hydrocarbon substances flow into the air outlet pipe 103, and then flow through the first control valve 104 and the waste tank connector 106 to the waste gas tank for centralized collection.

[0024] A water inlet pipe 107 is sealed and inserted into one side of the connecting shell 101, and a water outlet pipe 108 is sealed and inserted into the other side of the connecting shell 101. A connecting hose 8 is sealed and inserted into one end of the water outlet pipe 108. A second control valve 109 is threadedly connected to one end of the water inlet pipe 107 and one end of the water outlet pipe 108. The other end of one of the second control valves 109 is threadedly connected to a water inlet pump connector 110, and the other end of the other second control valve 109 is threadedly connected to a water outlet pump connector 111. Under the action of the water inlet pump, water is drawn into the water inlet pipe 107 and then into the hydrocarbon test tube. Then, under the action of the water outlet pump, the water in the hydrocarbon test tube is drawn into the connecting hose 8 and then discharged from the water outlet pipe 108 into the collection box for collection, thereby cleaning the hydrocarbon test tube.

[0025] A steel wire 2 is attached to one side of the inner wall of the air inlet pipe 102. The bottom end of the steel wire 2 extends out of the air inlet pipe 102. Under the blowing of the airflow, the steel wire 2 strikes the inner wall of the hydrocarbon test tube, thereby knocking off the hydrocarbon substances adhering to the inner wall of the hydrocarbon test tube, so as to fully collect the hydrocarbon substances in the test tube.

[0026] A perforated plate 3 is snapped between the inner circumference of the connecting shell 101. The water inlet pipe 107 and the connecting hose 8 pass through the perforated plate 3. A sealing cylinder 4 is glued to the bottom of the connecting shell 101. A clamp 5 is fitted around the outer circumference of the sealing cylinder 4. Hydrocarbon test tubes are inserted into the sealing cylinder 4, and then the clamp 5 is tightened to fix the hydrocarbon test tubes. The sealing cylinder 4 is a silicone cylinder.

[0027] The working principle of this embodiment is as follows: In use, the waste tank connector 106 is connected to the waste tank, then the compressed gas tank connector 7 is connected to the compressed gas tank, and the inlet water pump connector 110 and the outlet water pump connector 111 are connected to the inlet water pump and the outlet water pump respectively. Then, the hydrocarbon test tube is inserted into the sealing cylinder 4, and the clamp 5 is tightened to fix the hydrocarbon test tube. Then, the first control valve 104 is opened and the second control valve 109 is closed. The gas in the compressed gas tank is input into the hydrocarbon test tube through the second gas pipe 6, the first gas pipe 105, and the inlet pipe 102, thereby blowing up the hydrocarbon in the test tube. Then, under the flow of air, the hydrocarbon flows into the outlet pipe 103, and then flows through the first control valve 104 and the waste tank connector 106 to the waste gas tank for centralized collection.

[0028] At the same time, the airflow causes the steel wire 2 to strike the inner wall of the hydrocarbon test tube, thereby knocking off the hydrocarbon substances adhering to the inner wall of the hydrocarbon test tube, so as to fully collect the hydrocarbon substances in the test tube.

[0029] Then, close the first control valve 104, open the second control valve 109, and start the inlet and outlet pumps. Under the action of the inlet pump, water is drawn into the inlet pipe 107 and then into the hydrocarbon test tube. Then, under the action of the outlet pump, the water in the hydrocarbon test tube is drawn into the connecting hose 8 and then discharged from the outlet pipe 108 into the collection box for collection, thereby cleaning the hydrocarbon test tube. Then, remove the clamp 5 and disassemble the hydrocarbon test tube.
