[0003] However, the sodium sulfate solution in the test device main body will form crystals after the test device main body is cooled, so that a large amount of crystal residues will be generated in the test device main body during each use of the test device main body for the immersion and baking test, and the test device main body is very troublesome to clean, and therefore, the sand and gravel solidity test solution automatic feeding and discharging structure is needed. CONTENT OF THE INVENTION

[0005] The above-mentioned purpose of the application is achieved through the following technical scheme: a sand and gravel solidity test solution automatic feeding and discharging structure, which comprises a test device main body, a through opening penetrating into the inside of the test device main body, a mounting opening arranged on the bottom surface of the inside of the test device main body and a test frame body mounted in the mounting opening, the inside of the test frame body is uniformly provided with water leakage holes and mounting holes, a filter shell for placing sand and gravel is mounted in the mounting holes, a heating device for heating the test device main body is arranged in the test device main body, a water tank is arranged on the back surface of the test device main body, a water pump is mounted in the water tank, a water suction pipe is connected to the output end of the water pump, the end of the water suction pipe away from the water pump is located on the bottom surface outside the test device main body and is communicated into the mounting opening, and a cabinet door is hingedly mounted on the outside of the opening of the test device main body.

[0006] By adopting the technical scheme, the sand to be tested is placed in the filter shell, and the sodium sulfate solution is added into the test frame body, the cabinet door is closed, the heating device is started to heat the test device main body, the sand is tested, after the test is completed, the test device main body is rapidly cooled, and the residual sodium sulfate solution in the test device main body is pumped away by starting the water pump, so that the residual sodium sulfate solution with the sodium sulfate solution about to crystallize is moved into the water tank through the water pumping pipe, so that there is little sodium sulfate solution crystallization residue in the test device main body after the test is completed, and the staff does not need to clean the test device main body frequently, so that the staff can clean the test device main body more conveniently.

[0007] Further, the water pumping pipe is provided with a plugging device for plugging the water pumping pipe.

[0009] By adopting the technical scheme, although the water pump and the water pumping pipe are arranged, so that the staff can clean the test device main body more conveniently, when the staff adds the sodium sulfate solution into the test device main body, the sodium sulfate solution may flow into the water tank through the water pumping pipe connected to the water tank by the water pump, so that the staff needs to fill the water tank before adding the sodium sulfate solution, which is very inconvenient, and the arrangement of the plugging device solves the technical problem, by arranging the plugging device, when the sodium sulfate solution is added into the test device main body, the plugging motor is started to make the plugging plate around the water pumping pipe, so that the water pumping pipe is plugged, and the sodium sulfate solution cannot flow into the water tank, so that the staff can add the sodium sulfate solution more conveniently.

[0010] Further, the output end of the plugging motor extends through the water pumping pipe and protrudes from the bottom surface of the water pumping pipe, one end of the output end of the plugging motor protruding from the bottom surface of the water pumping pipe is fixedly connected with an identification strip for indicating the current state of the plugging plate, and the identification strip is parallel to the plugging plate.

[0011] Although the setting of the plugging device can make it more convenient for the worker to add sodium sulfate solution, the worker cannot observe the situation of the plugging plate in the water pumping pipe, so that the worker cannot control the timing of turning off the plugging motor, and the setting of the identification strip solves this technical problem, through the setting of the identification strip, after the worker starts the plugging motor to rotate, the state of the identification strip is observed, if the identification strip rotates to a horizontal state, it indicates that the plugging plate is in a horizontal state, at this time the plugging plate blocks the water pumping pipe, if the identification strip rotates to a vertical state, it indicates that the plugging plate is in a vertical state, at this time the plugging plate does not block the water pumping pipe, so that the worker can operate the plugging device more conveniently and accurately.

[0014] Through the above technical scheme, although the setting of the plugging structure makes it more convenient for the worker to add sodium sulfate solution, when the water pumping pump pumps water, the plugging plate will form a separation line in the water pumping pipe, which will cause the flow rate of the water flow to decrease, resulting in a decrease in the efficiency of the water pumping pump, and the setting of the acceleration structure solves this technical problem, through the setting of the acceleration structure, after the water flow flows through the plugging plate, it will flow into the acceleration pipe and flow in the acceleration groove in the acceleration pipe, the water flow flowing in the acceleration pipe collides with the inner wall of the curved acceleration groove, so that the acceleration pipe rotates in the water pumping pipe, the rotating acceleration pipe generates centrifugal force, thereby accelerating the flow of the water flow and improving the water pumping efficiency of the water pumping pump and reducing the influence of the plugging plate.

DETAILED DESCRIPTION

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] In the embodiment, reference is made to Figure 1 and Figure 2 ​The utility model provides a kind of sand firmness test solution automatic delivery and discharge structure, including test device main body 1, the through to test device main body 1 inside mouth, the installation port being opened in the bottom surface of test device main body 1 inside and the test frame body 10 being installed in installation port, leakage hole and mounting hole are evenly opened in test frame body 10 inside, mounting hole is equipped with the filter shell for placing sand, heating device for heating test device main body 1 is equipped in test device main body 1, water tank 2 is equipped in the back of test device main body 1, water pump is installed in water tank 2, water pump output end is communicated with water suction pipe 20, the end of water suction pipe 20 away from water pump is located in the bottom surface of test device main body 1 outside and is communicated to installation port, the outside of the mouth of test device main body 1 is hinged with cabinet door 11, the sand to be tested is placed in filter shell, and sodium sulfate solution is added to test frame body 10, close cabinet door 11, test device main body 1 is heated by starting heating device, and sand is tested, after test is completed, test device main body 1 is cooled quickly, and residual sodium sulfate solution in test device main body 1 is pumped away by starting water pump, so that residual sodium sulfate solution moves to water tank 2 by water suction pipe 20 with soon-to-be crystallized sodium sulfate solution, so that there is not much sodium sulfate solution crystallization residue in test device main body 1 after test is completed, so that staff does not need to clean test device main body 1 frequently, so that staff cleans test device main body 1 more conveniently.

[0028] Although the setting of water pump and water suction pipe 20 makes it more convenient for staff to clean test device main body 1, when staff adds sodium sulfate solution to test device main body 1, since water suction pipe 20 is communicated with water tank 2 by water pump, sodium sulfate solution can flow to water tank 2 along water suction pipe 20 when adding sodium sulfate solution, which makes staff need to fill water tank 2 before adding sodium sulfate solution, which is very inconvenient, in order to solve this technical problem, refer to Figure 3 In the embodiment, the water suction pipe 20 is provided with a plugging device 3 for plugging the water suction pipe 20, the plugging device 3 includes a plugging motor 30 fixedly arranged outside the water suction pipe 20 and having an output end extending into the water suction pipe 20, and a plugging plate 31 fixedly connected to the output end of the plugging motor 30 for plugging the water suction pipe 20, the plugging plate 31 is attached to the inner wall of the water suction pipe 20 around, by the setting of the plugging device 3, when adding sodium sulfate solution to test device main body 1, the plugging motor 30 is started to make the plugging plate 31 around attached to the state of the water suction pipe 20, and the water suction pipe 20 is plugged, so that sodium sulfate solution will not flow into water tank 2, making it more convenient for staff to add sodium sulfate solution.

[0029] Although the arrangement of the plugging device 3 can make it more convenient for the worker to add sodium sulfate solution, since the plugging plate 31 is located in the water pumping pipe 20, the worker cannot observe the situation of the plugging plate 31 in the water pumping pipe 20, so that the worker cannot control the timing of turning off the plugging motor 30. In order to solve this technical problem, in the embodiment, the output end of the plugging motor 30 penetrates through the water pumping pipe 20 and extends out of the bottom surface of the water pumping pipe 20, and one end of the output end of the plugging motor 30 extending out of the bottom surface of the water pumping pipe 20 is fixedly connected with an identification strip 32 for indicating the current state of the plugging plate 31, and the identification strip 32 is parallel to the plugging plate 31. Through the arrangement of the identification strip 32, after the worker starts the plugging motor 30 to rotate, the state of the identification strip 32 is observed. If the identification strip 32 rotates to a horizontal state, it indicates that the plugging plate 31 is in a horizontal state, at this time the plugging plate 31 blocks the water pumping pipe 20. If the identification strip 32 rotates to a vertical state, it indicates that the plugging plate 31 is in a vertical state, at this time the plugging plate 31 does not block the water pumping pipe 20. In this way, the worker can operate the plugging device 3 more conveniently and accurately.

[0030] Although the arrangement of the plugging structure makes it more convenient for the worker to add sodium sulfate solution, when the water pumping pump pumps water, the plugging plate 31 will form a separation line in the water pumping pipe 20, which will cause the flow rate of the water flow to decrease, and will cause the efficiency of the water pumping pump to decrease. In order to solve this technical problem, in the embodiment, an acceleration structure 4 for accelerating the water flow is arranged inside the water pumping pipe 20 away from the plugging plate 31. The acceleration structure 4 comprises an acceleration pipe 40 arranged to rotate in the water pumping pipe 20 and a curved acceleration groove 41 opened on the inner wall of the acceleration pipe 40 and penetrating through the front and rear ends of the acceleration pipe 40. The outer wall of the acceleration pipe 40 is attached to the inner wall of the water pumping pipe 20, and the acceleration groove 41 is opened with a plurality of acceleration grooves 41 uniformly distributed in the acceleration pipe 40. Through the arrangement of the acceleration structure 4, after the water flow flows through the plugging plate 31, it will flow into the acceleration pipe 40 and flow in the acceleration groove 41 in the acceleration pipe 40. The water flow flowing in the acceleration pipe 40 collides with the inner wall of the curved acceleration groove 41, so that the acceleration pipe 40 rotates in the water pumping pipe 20. The rotating acceleration pipe 40 generates centrifugal force, thereby accelerating the flow of the water flow and improving the water pumping efficiency of the water pumping pump and reducing the influence of the plugging plate 31.

[0031] In the embodiment, a water adding pump is arranged in the water tank 2, and the output end of the water adding pump is communicated with a water adding pipe 21 which is communicated into the test device main body 1. Through the water adding pump, it is more convenient for the worker to add sodium sulfate solution into the test device main body 1.

[0032] Referring to Figure 4In this embodiment, the upper end of the installation port is provided with a first liquid level sensor 22 connected with the water adding pump, and the lower end of the installation port is provided with a second liquid level sensor 23 connected with the water pumping pump. The first liquid level sensor 22 is used to prevent the sodium sulfate solution added by the water adding pump from overflowing the installation port and flowing out of the test device main body 1. The second liquid level sensor 23 is used to prevent the water pumping pump from continuing to pump water after pumping the sodium sulfate solution in the test device main body 1, thereby preventing the water pumping pump from being empty pumped.

[0033] Specific implementation process: first, start the plugging motor 30 to make the plugging plate 31 rotate to the state of attaching the water pumping pipe 20 around the periphery of the plugging plate 31, and plug the water pumping pipe 20. Then, place the sand and gravel to be tested in the filter shell, add sodium sulfate solution into the test frame body 10, close the cabinet door 11, start the heating device to heat the test device main body 1, and test the sand and gravel. After the test is completed, quickly cool the test device main body 1, and start the plugging motor 30 to make the plugging plate 31 rotate to the longitudinal state, so as to no longer plug the water pumping pipe 20. Then, start the water pumping pump to pump away the residual sodium sulfate solution in the test device main body 1, so that the residual sodium sulfate solution with the soon-to-be-crystallized sodium sulfate solution moves to the water tank 2 through the water pumping pipe 20, thereby making the test device main body 1 not have too much sodium sulfate solution crystallization residue after the test.

[0034] The embodiments of the specific implementation are the preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
