A piston 30 is arranged between the transit bin 52 and the lifting bin 53, a one-way filter valve body 22 is fixed between the feeding bin 51 and the transit bin 52, a first sealing ball 23 is arranged on one side of the transit bin 52 of the one-way filter valve body 22, and when the first sealing ball 23 is tightly contacted with the one-way filter valve body 22, the feeding bin 51 and the transit bin 52 are not communicated; when the first sealing ball 23 does not contact the one-way filter valve body 22, the feeding bin 51 and the transfer bin 52 are communicated. The first sealing ball and the one-way filter valve body form a one-way valve.
The piston 30 comprises a hollow part 33, the two ends of the hollow part 33 are a piston upper end 36 and a piston lower end 31 respectively, the piston lower end 31 is a sealing valve body, the piston upper end 36 fixes the piston rod 10, the piston upper end 36 can prevent a second sealing ball 34 from entering the lifting bin 53, the piston lower end 31 is provided with a lifting channel 32 communicated with the transfer bin 52, the second sealing ball 34 is arranged in the hollow part 33, and the surfaces of the piston upper end 36 and the piston lower end 31 on one side of the hollow part 33 are matched with the second sealing ball 34 to complete sealing contact. The lower piston end 31 (sealing valve body) and the second sealing ball 34 constitute a one-way valve.
A gap 39 for passing materials is arranged between the upper section of the piston 30 and the piston cylinder 20, a sealing ring 38 is fixed on the outer side of the lower section of the piston 30, and the gap 39 is not communicated with the transfer bin 52 through the sealing ring 38.
The side wall of the piston 30 is provided with a lateral channel 35, and the lateral channel 35 is used for communicating the gap 39 and the hollow part 33 and is used for material to pass through.
In order to prevent the first sealing ball 23 from moving too far, as shown in fig. 1, the lower section of the transfer chamber 52 is fixed with a baffle 24, and the baffle 24 is provided with a passage communicating with both sides thereof for the passage of the material, as shown in fig. 2.
As shown in fig. 7, three or four lateral channels 35 are provided, evenly distributed on the piston 30, for even material passing.
As shown in fig. 8, the middle portion of the outer contour of the sealing ring 38 is a recessed area 381, and the two end portions are protruded areas 382, the protruded areas 382 can perform a sealing function, and the recessed area 381 is not in contact with the piston cylinder 20, so that the frictional resistance to the piston during movement can be reduced.
The working principle is as follows:
when the plunger pump piston works, the following steps are carried out:
first, preparation. Referring to fig. 1, the feeding bin 51 of the plunger pump piston is placed downwards into a bin (such as a mixing tank), the piston rod 10 pushes the piston 30 to move to the bottom of the transfer bin 52, and the first sealing ball 23 and the second sealing ball 34 are both located at the lower end, so that the material in the bin automatically enters the feeding bin 51.
And secondly, lifting. As shown in fig. 2, the piston rod 10 drives the piston 30 to move upward (leftward in the drawing), the space of the transfer bin 52 is enlarged, and the air pressure therein becomes low, at this time, the first sealing ball 23 moves upward due to the external pressure, the passage of the one-way filter valve body 22 is opened, and the material passes through the one-way filter valve body 22 from the feeding bin 51 and enters the transfer bin 52 (see the direction of the arrow in the drawing).
And thirdly, compressing. As shown in fig. 3, the piston rod 10 drives the piston 30 to move downward, the space of the transit bin 52 is compressed, and at the same time, the pressure in the transit bin increases, at this time, the first sealing ball 23 moves downward due to the pressure, and is tightly attached to the one-way filter valve body 22, the passage of the one-way filter valve body 22 is closed, and the transit bin 52 becomes a closed space.
As shown in fig. 4, the piston rod 10 drives the piston 30 to move downwards continuously until it reaches the lowest point, in the process, the space of the transfer chamber 52 is compressed continuously, the material therein is pressed to enter the lifting channel 32 and meanwhile presses the second sealing ball 34 to move upwards to the upper end 36 of the piston, the material passes through the lifting channel 32 and enters the hollow part 33, and then enters the lifting chamber 53 from the lateral channel 35 and the gap 39.
And fourthly, lifting the materials. As shown in fig. 5, the piston rod 10 drives the piston 30 to move upward, the space of the middle rotating chamber 52 is enlarged and the pressure therein becomes low, and at this time, the second sealing ball 34 moves downward to the lower end 31 of the piston, and the second sealing ball 34 and the lower end 31 of the piston combine together to block the communication between the hollow part 33 and the middle rotating chamber 52.
At this time, as shown in fig. 1, the first sealing ball 23 is moved upward by the external pressure, the passage of the one-way filter valve body 22 is opened, and the material passes through the one-way filter valve body 22 from the feeding bin 51 into the transferring bin 52 (see the arrow direction in the drawing).
Meanwhile, as shown in fig. 2, the piston rod 10 drives the piston 30 to move upwards continuously, the connection between the transfer bin 23 and the lifting bin 23 is interrupted by the combination of the second sealing ball 34 and the lower end 34 of the piston, and the piston 30 pumps away the material in the lifting bin 53.
And continuously repeating the third step and the fourth step until the completion.
Other content participates in the prior art.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
