Description

Vertical filter press of full automated inspection filter cloth state

Technical Field

The utility model relates to a filtering and separating equipment field, in particular to vertical pressure filter of full automated inspection filter cloth state.

Background

In the prior art, the position of the tensioning guide roller changes with the opening and closing of the plate frame, and after the plate frame is opened, the tensioning guide roller is at the lowest position, and after the plate frame is closed, the tensioning guide roller is at the highest position. When new filter cloth is installed, the length of the filter cloth is adjusted, so that the tensioning guide roller is located at a proper position, but the filter cloth can be stretched or shortened in the using process, and the highest position and the lowest position of the tensioning guide roller can be changed. When the filter cloth extends to a certain degree, the tensioning guide roller reaches the lower limit position and does not move downwards any more, the tensioning guide roller loses the tensioning effect, and the driving guide roller slips along the filter cloth; after the filter cloth shortens to a certain degree, tensioning deflector roll reaches the upper limit position and no longer upwards moves, and tensioning deflector roll will drag the filter cloth and hinder closing of sheet frame, will cause the phenomenon such as filter cloth tear, dynamic pressure platen deflector roll support deformation at this moment.

The operator checks the position of the filter cloth tensioning guide roller each cycle, and forgetting the position may cause the above-mentioned problems.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a full automated inspection filter cloth state's vertical pressure filter, include: the tensioning chain wheel, the tensioning chain, the tensioning frame, the tensioning guide roller, the guide groove and the limit switch with the crank are arranged on the tensioning frame; the tensioning chain is meshed with the gear teeth of the tensioning chain wheel; the tensioning guide roller is slidably arranged in the guide groove; the limit switch is fixedly connected and arranged on the limit switch bracket; the limit switch bracket is fixedly connected and installed on the tensioning frame.

Further, the limit switch includes: an upper limit switch and a lower limit switch.

Furthermore, the upper limit switch is fixedly connected and installed at a position which is more than or equal to 200mm away from the upper edge of the guide groove, and the lower limit switch is fixedly connected and installed at a position which is more than or equal to 200mm away from the lower edge of the guide groove.

Further, the type of limit switch includes: JLXK1-111 and YBLX-19.

Further, the fixed connection mode includes: screw connection and bolt connection.

Furthermore, the tensioning chain wheel and the limit switch are controlled by a PLC.

Further, when the tensioning guide roller moves to the position of the limit switch, the crank is shifted, and the PLC detects a switch closing signal and gives an alarm.

Has the advantages that:

1. the utility model discloses a technical scheme, be equipped with upper and lower limit switch on the tensioning frame, stopped because of the extension of filter cloth or shortened the equipment problem that arouses.

2. The utility model discloses a technical scheme, after triggering limit switch, PLC sends out the suggestion operating personnel of reporting to the police, need not every circulation and all inspects filter cloth tensioning deflector roll position condition.

Description of reference numerals: 1. the device comprises a tensioning chain wheel 2, a tensioning chain 3, a tensioning frame 4, a guide groove 5, a tensioning guide roller 6, a limit switch bracket 7, an upper limit switch 8, a lower limit switch 9, filter cloth 10 and a crank.

Detailed Description

A full-automatic vertical filter press that detects filter cloth state includes: the device comprises a tensioning chain wheel 1, a tensioning chain 2, a tensioning frame 3, a tensioning guide roller 5, a guide groove 4 and a limit switch with a crank 10; the tensioning chain 2 is meshed with the gear teeth of the tensioning chain wheel 1; the tensioning guide roller 5 is slidably arranged in the guide groove 4; the limit switch is fixedly connected and arranged on the limit switch bracket 6; the limit switch bracket 6 is fixedly connected and installed on the tensioning frame 3.

Example one

Referring to fig. 1-2, first, a tension sprocket 1 operates to move a tension chain 2 engaged with the tension sprocket 1; the tensioning guide roller 5 is slidably arranged in the guide groove 4 and moves downwards along the guide groove 4; the lower limit switch is connected to the tensioning frame 3 through a limit switch bracket 6 by a screw, is 200mm away from the lower side of the guide groove 4, and is provided with a crank 10; when the tensioning guide roller 5 moves downwards to the lower limit switch position, the crank 10 is shifted, and the PLC detects a switch closing signal and gives an alarm; the filter cloth 9 is handled in time by the staff.

Example two

Referring to fig. 1-2, the tension sprocket 1 does not work, the tension sprocket 1 does not limit the tension guide roller 5 to passively ascend, the tension guide roller 5 is in a free state, and the tension guide roller 5 ascends; the upper limit switch is connected with the tensioning frame 3 through a limit switch bracket 6 by screws and bolts, is 200mm away from the upper edge of the guide groove 4, and is provided with a crank 10; when the tensioning guide roller 5 moves upwards to the upper limit switch position, the crank 10 is shifted, and the PLC detects a switch closing signal and gives an alarm; the filter cloth 9 is handled in time by the staff. It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
