JPS63258611A - Constitution of filtration wall of filter plate in filter plate-type filter - Google Patents

Abstract

PURPOSE:To make a filtration wall flexible, elastic and suitable for use in a forced dehydration filtration by forming the filtration wall by concatenating split elements with a spring or spring-tensioned connecting material. CONSTITUTION:Split elements are connected by passing flexible wire W with one end Wa attached to an inner ring 8 through the through holes of the elements. The wire W is connected with a spring 11 in an arrangement hole 9a, which communicates to the through holes, provided in an outer ring 9. The other end of the spring 11, connected to wire Wb of the same type, is tensely fixed to a stopper 12. A split element 1 located at an inner-most circumference has an attachment concave groove 1a formed on an internal circumferential end face so that the split element may be engaged with a projecting line 8a of the inner ring 8. On the external circumferential end face of split element 6 located at an outer-most circumference, an attachment concave groove 6a which fits into an attachment projecting line 9a of the other ring 9 is provided.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to the structure of a passing wall of a furnace plate used in parallel in a 'y'18 process. Conventionally, many furnace plates of this kind have been integrally molded from metal or plastic, and each has been formed to a size appropriate to the passing machine used.

It is also conceivable to make only the overwall part plastic and attach it to the metal frame, but even in this case, it is necessary to make the overwall part a size appropriate for the process.

According to this, there is a problem that a furnace plate of that size cannot be used for anything other than one process.

Furthermore, even if a part of the overwall part is damaged, it is necessary to replace the entire part, which is uneconomical.

(Means for Solving the Problems) Therefore, the present invention has the following advantages: - By configuring the overwall portion by consecutively arranging divided bodies, it is possible to form overwall portions of different sizes, and furthermore, the filtration wall is formed in a continuous manner. It is an object of the present invention to provide a device which can be formed into a material having excellent flexibility and elasticity and can be used even in intensive dehydration.

(Example) Hereinafter, details of the present invention will be explained with reference to illustrated embodiments.

The temporary wall portion S of the furnace plate of this example shown in FIG. 1 is fitted into a metal outer ring 9, and the outer ring 9 is welded and fixed to the outer frame F.
A handle Fa having rollers is provided protruding from the outer frame F to form a furnace plate.

- The overwall part S is made up of divided bodies 1 each having a size such that an area divided by eight straight lines radiating from the center at the same intervals is further divided by five concentric circles from the center at the same intervals. , 2, 3, 4, 5.6 are molded from plastic, and an engaging protrusion Ka is provided protrudingly on one peripheral end surface of each divided body, and an engaging recess Kb is formed on the other peripheral end surface. An engaging recess Na of the divided body is provided on the outer peripheral end surface of the divided body and is connected to the outer periphery of the divided body.
An engaging convex portion Nb that engages with the split body is provided in a protruding manner, and an engaging concave portion Na that engages with the engaging convex portion Nb of the divided body connected to the inner circumference is provided on the inner circumferential end surface thereof. (See Figure 2), each divided body has a through hole E in the center that communicates with the divided body when they are connected. In addition, since the sizes of the respective divided bodies are different, the sizes of the engaging recesses Na and the engaging protrusions Nb formed in the respective divided bodies are as follows.

The numbers are also different.

Then, each of the divided bodies of the same size is sequentially connected to each engaging convex portion Ka.
and the engagement concave part kb in a concentric manner, and as shown in FIG. There is.

At this time, the flexible metal wire W, which has the hearth Wa fixed to the inner ring 8, is passed through the through hole E of the divided body to lock each divided body.

The metal wire W is connected to a spring 11 in an arrangement hole 9a that communicates with a through hole E provided in the outer ring 9, and the other end of the spring 11 is connected to the same metal wire wb and tensioned on a stopper 12. The settings are fixed.

In addition, the divided body 1 located at the innermost periphery is the convex strip 8 of the inner ring 8.
An engagement recess 1s1a is formed on the inner peripheral end surface so that it can be engaged with a! & An engagement groove 6a that engages with the engagement protrusion 9a of the outer ring 9 is protrudingly provided on the outer peripheral end face of the divided body 6 located on the outer periphery (see Fig. 3 1@).

For this purpose, the ring 8.9 is engaged with the divided body 1.6 to fix the temporary wall portion S by the engagement of the divided body. Note that the outer ring 9 is divided into two parts, and the divided body 6 can be engaged with the outer ring 9 by fastening with bolts 10.

In this way, according to this example, the temporary wall portion S can be formed by simply manufacturing 6M type divided bodies and joining them, and by adjusting the continuous arrangement of the divided bodies in the outer circumferential direction, different sizes can be formed. By adding a separately formed dividing body to the outermost periphery, a temporary wall of any size can be formed.

In addition, since the metal wire W is strongly stretched through the spring 11 by the tension of the metal wire wb, even if the overwall part bends temporarily, it returns to its original position due to the elastic restoring force of the metal wire W when the pressure is removed. be.

Note that the furnace plate may be used by attaching the furnace cloth through the draining plate in the same manner as in the past.

Although this example is configured as described above, the present invention is not limited thereto.

For example, the shape of the engaging portion formed on each divided body does not matter.

Further, the continuous arrangement of the divided bodies is also appropriate, and the joint surfaces may be discontinuous and the divided bodies may be arranged in a row at different levels as shown in FIG.

Furthermore, the shape of the overwall part is also arbitrary, and it can also be formed as a divided body as shown in FIG.

In order to form one divided body, it is sufficient to have three or more straight lines with the same spacing centered on the same center, and this partitioned area is further divided into three or more bodies at appropriate intervals in a direction perpendicular to the straight line or in a concentric circle. A divided body is best, but any divided body that can be engaged and connected to form a temporary wall may be used.

Further, a connecting material for connecting the respective divided bodies and imparting flexibility to the temporary wall portion is also suitable, and as shown in Fig. 6, the outer periphery is secured by a spring 14 secured to the four parts 13a so as not to come off. It is formed by snapping the divided bodies 13 connected in one direction to each other and connecting the divided bodies 13 connected in any direction to each other using springs 15 locked to the four parts 13b as shown in FIG. Flexible elasticity may be imparted to the filtration wall.

Further, since the divided body is made of plastic, a drain groove may be formed on the surface or a drain hole or the like may be integrally formed inside, and the configuration in which the temporary wall portion is held by the furnace plate frame is not limited.

(Effects of the Invention) Therefore, according to the present invention, since a temporary wall is formed by joining the divided bodies, it is only necessary to mold one divided body in plastic, resulting in an inexpensive temporary wall. It can be formed into any size, and by connecting the divided bodies with a spring or a connecting material tensioned by a spring, the temporary wall part has flexible elasticity, making it possible to perform powerful dewatering. There is an effect that can be done.
