Description

Filter press filter plate handle and sliding shoe thereof

Technical Field

The utility model relates to a filter press filter plate handle. In particular to a filter plate handle for a side lever type filter press. The utility model discloses still relate to a piston shoe that is used for pressure filter plate handle.

Background

The side bar type filter press is a typical solid-liquid separation device in the applications of chemical industry, food industry, municipal industry and the like. The handle of the side lever type filter press belongs to a common vulnerable part. In long-term use, the bottom of the handle is gradually abraded, and filter plate groups and pull plates are unsmooth after the abrasion loss exceeds a certain value, so that the problems that the pull plate trolley cannot be positioned, is loosened midway and the like are caused.

The common design in the existing market is the design of a roller or a dovetail plate, and the problem that the replacement is complex and the flat-bottom handle is not suitable exists.

Disclosure of Invention

In order to solve the technical problem, the utility model provides a pressure filter plate handle installs in the side at the filter plate frame of pressure filter, and this pressure filter plate handle includes: a resting part, the bottom side of which is suitable for being placed on the side bar of the filter press; and a handle portion adapted to be wrenched; wherein the placement portion has a slipper that is detachably disposed on the main body portion of the placement portion and covers a bottom side of the main body portion of the placement portion.

Because the shoes isolate the filter plate handle from the side bars, wear is significantly reduced relative to filter plate handles without shoes. Furthermore, since the slide shoe is detachable from the main body of the resting portion, it can be replaced in time when the slide shoe is worn, which is of great importance particularly when the filter plate handle is of the integrally welded type, since it cannot be easily removed from the filter plate frame of the filter press, and must be avoided as much as possible.

According to an embodiment of the invention, the shape of the sliding shoe is designed to cover the bottom side of the main part of the resting portion and to be detachably connected to the main part of the resting portion on both the front and rear sides of the main part of the resting portion. This design does not exclude the case where the shoes surround the entire upper and lower and front and rear sides of the main body portion of the placement portion. Preferably, however, the slipper has a semi-enclosed shape with an upward opening.

According to one embodiment of the invention, the detachable connection between the sliding shoe and the main part of the holder is formed on both sides of the filter plate handle, preferably by means of a spring pin or a bolt. Wherein, in case of needing to realize the quick assembly and disassembly of the slipper, the spring pin is more preferable, and the bolt can provide more stable connection for the slipper.

Alternatively, it is also conceivable, of course, for the slide shoe to be detachably connected to the body part of the placement part on the underside of the filter plate handle, for example by means of a countersunk screw which is fastened to the underside of the body part of the placement part of the filter plate handle, so that the countersunk screw does not project beyond the contact surface of the slide shoe with the side bar.

In this case, the slide shoe does not have to form an enclosure for both sides of the body portion of the rest of the filter pad handle, but may be arranged only on the underside of the body portion of the rest.

According to the utility model discloses an on the other hand, the utility model discloses still provide a piston shoe that is used for above-mentioned pressure filter plate handle, this piston shoe includes: a bottom portion adapted to be disposed on a bottom side of the body portion of the rest, the bottom portion having an upper side shaped to match the bottom side of the body portion of the rest and a lower side shaped to rest on a side bar of the filter press; and a side portion adapted to be detachably fixed to the main body portion of the resting portion.

Preferably, the side portion of the shoe is fixed to the main body portion of the resting portion by a bolt or a spring pin.

According to an embodiment of the present invention, the sliding shoe is formed by two half-parts which are assembled together, and the two half-parts are connected to each other by the sliding shoe and the detachable connection between the main body parts of the placing part.

Detailed Description

Fig. 1 schematically shows a perspective view of a filter plate handle according to an embodiment of the invention. As shown in fig. 1, the utility model provides a filter press filter plate handle includes: a rest 11, the bottom side of which is adapted to rest on the side bar of the filter press; a handle 12 adapted to be wrenched; the placement portion 11 has the shoe 2.

The slide shoe 2 is detachably arranged on the main body part of the rest part 11 and covers the bottom side and the front and rear sides of the main body part of the rest part 11, and in the embodiment shown in fig. 1, the slide shoe 2 semi-surrounds the rest part 11 of the filter plate handle of the filter press. The shoe 2 includes: a bottom portion 21 adapted to be arranged on the bottom side of the main portion of the rest 11, the bottom portion 21 having an upper side shaped to match the bottom side of the main portion of the rest 11 and a lower side shaped to be placed on a side bar of the filter press; and a side portion 22 adapted to be removably fixed to the main body portion of the rest portion 11

When the filter plate of the filter press slides back and forth on the side bar, the sliding shoe 2 protects the filter plate handle of the filter press from abrasion, even if the sliding shoe 2 is seriously abraded, only the sliding shoe 2 needs to be replaced, the integral structure of the filter plate handle of the filter press does not need to be replaced, and the use and maintenance period of the equipment is prolonged.

Fig. 2 schematically shows a cross-sectional view of a filter plate handle according to an embodiment of the invention, as shown in fig. 2, the slide shoe 2 is connected to the rest 11 of the filter plate handle of a filter press via a pin hole 3 and a spring pin 4.

Put both sides around the main part of portion 11 and bottom and all surrounded by piston shoes 2, the filter press filter plate handle is more firm on overall structure, also makes the main part of putting portion 11 avoid causing in the arm-tie working process and collide with simultaneously.

Fig. 3 schematically shows a perspective view of a slide shoe according to an embodiment of the invention, as shown in fig. 3, the slide shoe 2 has a bottom 21 and a side 22, and the 2 structural form of the slide shoe can be specifically designed according to the shape of the filter plate handle rest of the filter press to adapt to filter plate handles of different structural forms. This is of particular interest for repairing and adapting existing filter plate handles, since the slide shoe 2 can be matched with a suitably designed upper side shape to the underside of the filter plate handle, which is heavily worn by the side bars.

The side portions 22 have pin holes through which bolts or spring pins can pass. The sliding shoe 2 is fixed on the filter plate handle by bolts or spring pins at two sides of the filter plate handle of the filter press.

In an alternative embodiment, not shown, the slide shoe is secured to the filter plate handle at the bottom side of the filter plate handle. The bottom of the sliding shoe can be fixed on the bottom side of the placing part of the filter plate handle of the filter press through a sunk screw.

In a further alternative embodiment, not shown, the slipper is made up of two halves, joined to each other by a removable connection between said slipper and the main body portion of said rest.
