The liquid inlet on the top is relatively matched; the upper end of the hopper is provided with a matching top cover, the top cover is provided with a piston, and the piston moves up and down in the hopper; the middle part of the filling part is provided There is a total one-way valve; the lower end of the filling part is provided with a filling nozzle, and a sub-one-way valve is also arranged between the filling nozzle and the filling part.

Preferably, the diameter of the liquid outlet in the hopper is smaller than the diameter of the liquid inlet on the filling part.

Preferably, there are multiple filling nozzles, and the filling nozzles are circumferentially arranged around the lower end of the filling part.

Preferably, the main one-way valve is a straight-through one-way valve, and the sub-one-way valve is a right-angle one-way valve.

The beneficial effect of the utility model is that by setting the piston in the top cover, setting the general one-way valve in the filling part and setting the sub-one-way valve at each filling mouth, and then pushing the concentrated liquid in the hopper from top to bottom by the piston. Thick liquid is smoothly pressed out from the filling nozzle for filling, which achieves the filling purpose of the utility model for thick liquid. At the same time, the piston of the utility model is arranged in the top cover to facilitate disassembly, maintenance and replacement at any time. The one-way valve is helpful to the overall control of the whole filling process, and the one-way valve at each filling nozzle is conducive to the individual control of each filling nozzle.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1, a piston type filling device includes a hopper 1, a filling part 2 and a top cover 3; wherein the hopper 1 is placed at the upper opening of the filling part 2 in an inverted cone shape, and the filling part 2 The upper opening of the corresponding hopper 1 has a corresponding inverted cone-shaped opening; the lower end of the hopper 1 is provided with a liquid outlet 11, and the upper opening of the filling part 2 is provided with a liquid inlet 21, wherein the hopper 1 The liquid outlet 11 of the liquid outlet 11 is relatively matched with the liquid inlet 21 on the filling part 2, and the diameter of the liquid outlet 11 in the hopper 1 is smaller than the diameter of the liquid inlet 21 on the filling part 2; the upper end of the hopper 1 is provided with The top cover 3 matched with it, and the top cover 3 is provided with a piston 4. When the top cover 3 is matched with the hopper 1, the piston 4 can move up and down in the hopper 1; Directional valve 5, which can control whether the thick liquid entering from the liquid inlet 21 continues to flow down to the lower end of the filling part 2; the lower end of the filling part 2 is provided with a filling nozzle 7, and the filling nozzle 7 and the filling part A sub-check valve 6 is also arranged between 2.

Preferably, there are multiple filling nozzles 7 arranged in a circumferential arrangement around the lower end of the filling part 2 .

Preferably, the main one-way valve 5 is a straight-through one-way valve, and the sub-one-way valve 6 is a right-angle one-way valve.

A piston type filling device, the filling process is as follows:

First, the piston filling device is powered on, the filling nozzles 7 controlled by the sub-check valve 6 are all closed, the main check valve 5 is closed, and the piston 4 is located in the top cover 3 . When the thick liquid is added to the hopper 1, the device starts to work. First, the main one-way valve 5 is opened, and the piston 4 located in the top cover 3 starts to move from top to bottom to push the thick liquid to fill the filling part 2, and then open Each sub-check valve 6 makes the filling nozzle 7 open, and then the piston continues to move from top to bottom to push the thick liquid again so that it is pressed out from each filling nozzle 7 for filling.

In the piston type filling device provided by the utility model, a piston is set in the top cover, a total check valve is set in the filling part, and a sub-check valve is set at each filling mouth, and then the piston pushes the hopper from top to bottom. The thick liquid inside is smoothly pressed out from the filling nozzle for filling, which achieves the filling purpose of the utility model for the thick liquid. At the same time, the piston of the utility model is arranged in the top cover to facilitate disassembly, maintenance and replacement at any time. Setting the total one-way valve is helpful to the overall control of the entire filling process, and setting the sub-one-way valve at each filling nozzle is conducive to the individual control of each filling nozzle.

Although the specific implementation of the utility model has been described above in conjunction with the accompanying drawings, it does not limit the protection scope of the utility model. Those skilled in the art should understand that on the basis of the technical solution of the utility model, those skilled in the art do not need to Various modifications or deformations that can be made with creative efforts are still within the protection scope of the present utility model.
