Abstract

PURPOSE:To facilitate replacements by a method in which a filter plate is formed by connecting together 12 or more elements in total obtained by dividing firstly the whole eircular area into 3 or more equal sectors and secondly each sector into r or more segments with concentric circles. CONSTITUTION:A filtration wall S is composed of plastic split elements 1,2,3,4,5 and 6 of such a size as divided by five concentric circles at the same interval from the center based on an area divided by eight radial straight lines at the same interval from the center. On the peripheral end face of one side of each split element, an attachment projecting part Ka is provided, and at the time, an attachment recessed part is formed on the peripheral end face of the other side. Further, attachment projecting parts Nb which fit into attachment recessed parts Na of the split elements provided continuously on the outer periphery are formed on the cuter peripheral end face of each split element. At the same time, attachment recessed parts Na which fit into attachment projecting parts Nb of the split elements, provided continuously on the inner periphery, are formed on the inner peripheral end face.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to the structure of a filtration wall of a plate, which is used in parallel in a large number of f-plate filtration machines (problems to be solved by the invention). ) Traditionally, many of these door plates have been integrally molded from metal or plastic, and are sized to suit the type of passing machine used.

It is also possible to make only the temporary wall part plastic and attach it to the metal frame, but even in this case, it is necessary to make the temporary wall part a size appropriate for the machine.

According to this, there is a problem that a plate of that size cannot be used in anything other than a filter for that purpose.

Furthermore, even if the filter section of the filter wall section were damaged, it was necessary to replace the entire filter section, which was uneconomical.

(Means for Solving the Problems) The object of the present invention is to provide a filter wall that can be formed into filter walls of different sizes and that can be partially replaced.

For this reason, the present invention provides an area in which an area divided by three or more straight lines with the same distance from the center is further divided into three or more lines at appropriate intervals in a direction perpendicular to the straight lines, or three or more concentric circles from the center. molding each divided body of a size divided by plastic, an engaging convex portion protruding from one side peripheral end surface of each divided body, and an engaging recess formed on the other side peripheral end surface,
An engaging part that engages with an engaging part of the divided body connected to the outer periphery is provided on the outer peripheral end surface of each divided body, and an engaging part that engages with the engaging part of the divided body connected to the inner periphery is provided on the inner peripheral end surface. The structure includes an engaging part that engages with the filter wall, and the respective divided bodies are successively engaged with each other at each engaging part to form an integrated filtering wall.

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

The filter wall 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 areas partitioned by eight radial straight lines at the same intervals from the center are further partitioned 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), and
Since the sizes of the respective divided bodies are different, the sizes and numbers of the engaging recesses Na and the engaging protrusions Nb formed in the respective divided bodies are also different.

Then, as shown in FIG. 4, the divided bodies of the same size are sequentially engaged with each other in a concentric manner at each engaging convex portion Ka and each engaging concave portion kb, and at the same time, as shown in FIG. An integrated filtration wall S is formed by engaging and communicating with the engaging recess Na.

Note that the dividing body l located at the innermost periphery has an engaging recess 1a formed on its inner peripheral end face so that it can engage with the convex portion 8a of the retaining ring 8, and the outer periphery of the dividing body 6 located at the outermost periphery An engagement convex portion 6a that engages with an engagement concave portion 9a of the outer ring 9 is provided on the end surface.
is protruding (see Figure 3).

For this purpose, the rings 8 and 9 are engaged with the divided bodies 1 and 6, and the temporary wall portion S is fixed by the engagement of the divided bodies. 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 six types of divided bodies and combining them. In addition, it is possible to make the temporary wall part as small as the dividing body 6 that is continuous to the outermost circumference, and to separate the divided body that is continuous to the outer circumference of the dividing body 6 that is the outermost circumference. By molding, adding and connecting them, it is possible to create a filtration wall of any size.

Although the temporary wall portion may be bent at appropriate times, it can be used as a single flexible plate as long as the divided body does not come off. The f-board can be used in the same way as in the past, through a draining board; by covering it with cloth.

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

For example, regardless of the shape of the engaging portion formed on each divided body, it may be configured to slide and fit as shown in Figure 5, or it may be configured to engage using the elasticity of plastic as shown in Figure 6. good.

Further, the state in which the divided bodies are connected is arbitrary, and they may be connected in a state in which the joint surfaces are discontinuous as shown in FIG. 7.

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 addition, in order to form a 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. It suffices if it is a divided body.

Further, since the divided body is made of plastic, a drainage groove may be formed on the surface, or a drainage hole or the like may be integrally formed inside.

Furthermore, the configuration in which the temporary wall portion is held by the plate frame is also not limited.

(Effects of the Invention) Therefore, according to the present invention, the temporary wall portion is formed by joining the divided bodies, and the following effects are achieved.

(a) It is only necessary to plastic mold a divided body of the type that forms one sectioned section, resulting in an inexpensive temporary wall section.

(o) It is possible to form a filtration wall of any size by adjusting the number of divided bodies to be joined or by adding parts, and - it has a great effect that it can be changed and used depending on the type of filter.

(c) Since it is composed of a divided body, only the damaged part can be replaced, making it economical and easy to maintain.

(d) Since it is a divided body, it can be joined on site, making it suitable for transportation.
