Description

Technical Field

[0001] The utility model relates to the technical field of a papermaking machine pressing mechanism, in particular to a papermaking machine pressing mechanism. Background Art

[0002] A screw press is used to remove water from pulp. However, in actual use, we found that the efficiency of using a screw press is not high when processing pulp with a moisture content higher than 50%, and the investment cost is relatively high. Therefore, in order to improve the initial water control of pulp with high moisture content, this case is proposed. The purpose is to pre-control the water content of the pulp before using the screw press so that its moisture content quickly reaches below 10% in the pulp material box, which is conducive to improving work efficiency. Utility Model Content

[0003] The technical problem to be solved by the present invention is: in order to overcome the above problems, a paper machine pressing mechanism is provided, which solves the above problems.

[0004] The utility model solves the technical problem by adopting the following technical solutions:

[0005] A papermaking machine pressing mechanism includes a pulp material box with an opening, a filter press for squeezing and draining water is fixedly provided on the outside of the pulp material box, the filter press is communicated with the pulp material box, the pulp material box is used to hold pulp, and a reciprocating linear drive unit is also fixedly provided on the pulp material box, a piston pressure plate sliding in the filter press is fixedly provided at the front end of the telescopic rod of the reciprocating linear drive unit, the side wall of the piston pressure plate is slidingly sealed with the filter press, a detachable threaded connection end is connected to the other end of the filter press, and a delay tube is fixedly provided at the front end of the threaded connection end.

[0006] Preferably, a spiral sheet is welded and fixed in the delay tube, and the obstruction of the thin tube of the delay tube and the spiral sheet increases the pressure of the material in the filter press under the push of the piston pressure plate, thereby separating the water. It should be noted that delay tubes of different diameters can be selected according to the need to control the water content or variable pitch spiral sheets can be used to achieve the effect of changing the size of the blocking force at the discharge port.

[0007] Preferably, the threaded connection end is fixed to the front end of the filter press by threaded connection to facilitate sealing and disassembly.

[0008] Preferably, a guide tail sleeve that is coaxial with and of equal diameter to the filter press cylinder is fixedly provided in the pulp material box, and a plurality of feeding ports are provided on the guide tail sleeve at annular intervals. The guide tail sleeve is used to guide the piston pressure plate after it is pulled out of the filter press cylinder to ensure that the piston pressure plate is accurately pushed into the filter press cylinder, and the feeding port is used to supply pulp into the filter press cylinder after the piston pressure plate exits the filter press cylinder.

[0009] Preferably, a front frame plate is fixedly provided at the front end of the filter press cylinder for supporting the filter press cylinder.

[0010] Preferably, a water collecting tray is fixedly provided between the pulp material box and the front frame plate for collecting waste water from the filter press, and a drainage pipe is provided on the water collecting tray for centralized discharge of waste water.

[0011] The advantages and positive effects of the present invention are: high-water content pulp is quickly squeezed by adopting a linear compression method, and the retardation force formed by the retardation tube located at the front end of the equipment allows water to separate and flow out from the paper fibers, quickly reducing the volume of the pulp raw material and facilitating the subsequent final squeezing and water control.
