Description

Technical Field

[0001] The utility model relates to the technical field of circulation and dispersion, in particular to a drainage system with low residue, anti-deposition and the medium can contain particles. Background Art

[0002] In the existing drainage system, the pump body is horizontally placed, and the drainage needs to branch out from the circulation pipeline and use a valve body to switch. When the liquid is lower than the water outlet, it is very difficult to drain the remaining liquid; if the drainage is carried out through a branch in the pipeline, the particles in the medium usually deposit in the area between the branch and the valve body during the circulation test; the valve body fails due to particle accumulation when passing through the medium with particles; and most valve bodies cannot be used under the working conditions where the medium contains particles. Content of the Utility Model

[0003] The purpose of the utility model is to provide a drainage system with low residue, anti-deposition and the medium can contain particles, so as to solve the problems put forward in the above background art.

[0004] For the above purpose, the utility model provides the following technical solutions:

[0007] The cup base of the sample cup is connected to the pump body by screws, and the cavity of the sample cup is communicated with the cavity inside the pump body;

[0008] One end of the impeller shaft is connected to the motor, and the other end is connected to the impeller;

[0009] The impeller shaft is connected to the impeller and inserted into the cavity of the pump body through the sample cup;

[0010] The upper end surface of the bracket is inclined, and the pump body is fixed on the inclined surface of the bracket;

[0011] The pump body is provided with a water outlet, and the upper end of the sample cup is provided with a water return port;

[0012] The water outlet on the pump body is connected to the sample pool through the pipeline a, and the water return port on the sample cup is connected to the sample pool through the pipeline b to form a circulation;

[0013] The valve body is connected to the side wall of the pump body by welding, and through holes are opened at the welding positions of both to drain the residue;

[0014] The sealing body passes through the inner cavity of the valve body and corresponds to the position of the round hole in the valve body;

[0015] A drain port is provided at the lower end of the valve body and is in communication with the round holes in the valve body and the pump body;

[0016] The linear motor passes through the circuit board and is inserted onto the sealing body in the valve body. The sealing body is driven to move forward by the extension of the linear motor and abuts against the valve body to form a seal.

[0017] In a preferred embodiment of the described low-residue, anti-deposition, and particle-containing medium drainage system, a moving diaphragm is provided in the sealing body to ensure that the sealing body does not leak water during movement.

[0018] In a preferred embodiment of the described low-residue, anti-deposition, and particle-containing medium drainage system, the inclined surface of the bracket has the same inclination angle as the inclined surface of the sample cup holder.

[0019] In a preferred embodiment of the described low-residue, anti-deposition, and particle-containing medium drainage system, the sample cup and the pump body in the system are filled with a medium, which is water or other solvents, and there is also a sample in the medium, and the sample is particles insoluble in the medium.

[0021] In a preferred embodiment of the described low-residue, anti-deposition, and particle-containing medium drainage system, the moving diaphragm can be designed to use a special-shaped rubber diaphragm or a plastic sheet.

[0022] Working principle of a low-residue, anti-deposition, and particle-containing medium drainage system: The rotation of the motor drives the impeller to rotate through the impeller shaft, generating a centrifugal force in the valve body. This causes the medium to pass through the outlet, through pipeline a, into the sample pool for testing, and then through pipeline b back to the sample cup from the return port. At this time, the sealing body abuts against the pump body and the medium does not leak out. After the test is completed and the liquid needs to be drained, the linear motor moves backward to drive the sealing body away from the pump body. During the movement, the moving diaphragm ensures that the sealing body can complete the movement without the medium leaking from the moving position. The medium is quickly discharged from the drain port of the pump body under the action of centrifugal force and discharged through the drain port on the valve body. Since the pump body is inclined, even when the remaining amount of the liquid is very low, all the liquid can flow from the drain port of the pump body into the valve body without residue. During the discharge process, the medium continuously flushes the sealing body so that no particles remain on it to affect the seal. After the drainage is completed, the linear motor extends to drive the sealing body to move forward and abut against the valve body again to form a seal. At this time, the medium can be re-introduced for the next test.

[0023] Beneficial effects

[0024] The technical solution of the present utility model reduces the residual amount of the medium after drainage, and there is no need to add a branch in the pipeline to prevent particle deposition, solving the problem that most valve bodies cannot be used under the working conditions where the medium contains particles.

[0037] The seal body 8 passes through the inner cavity of the valve body and corresponds to the position of the round hole of the valve body 6.

[0045] The working principle of a drainage system with low residue, anti-deposition, and the medium can contain particles: The motor rotates to drive the impeller to rotate through the impeller shaft, generating a centrifugal force in the valve body, so that the medium passes through the water outlet through pipeline a, completes the test in the sample cell, and then returns to the sample cup from the water return port through pipeline b. At this time, the seal body abuts against the pump body and the medium will not flow out. After the test is completed, the liquid needs to be drained. At this time, the linear motor moves backward to drive the seal body to disengage from the pump body. During the movement, the moving diaphragm ensures that the seal body can complete the movement and the medium will not flow out from the moving position. Under the action of the centrifugal force, the medium is quickly discharged from the drain port of the pump body and discharged through the drain port on the valve body. Since the pump body is inclined, the liquid can all flow into the valve body from the drain port of the pump body even when the remaining amount is very low without residue. During the discharge process, the medium can continuously wash the seal body so that no particles will remain on it to affect the seal. After the drainage is completed, the linear motor extends to drive the seal body to move forward and abut against the valve body again to form a seal. At this time, the medium can be re-introduced for the next test.
