Filtering plate mold and method for producing filtering plate by using same

Abstract

The invention provides a filtering plate mold and a method for producing a filtering plate by using the same, belonging to the technical field of the water treatment and aiming at solving the problems that the prior filtering plate mold has poor safety and low evenness and the prior method for producing the filtering plate leads to high construction difficulty and large construction workload. Thefiltering plate mold comprises a cross beam and a template. The top surface of the template is provided with a plurality of positioning pieces. One end of each positioning piece can be connected withthe template through a detachable structure, and the other end can extend out of the edge of the template and can be placed on the top surface of the cross beam. The method for producing a filtering plate by using the filtering plate mold comprises the following steps: preparing for the components of the filtering plate mold; mounting the filtering plate mold; arranging reinforcing steel bars running through a filtering tank on the template; pouring concrete to form the filtering plate; and dismounting the template after the concrete being hardened and formed. The filtering plate mold has theadvantages of easy and convenient installation and high mechanical strength; the method for producing the filtering plate by using the filtering plate mold can ensure the high evenness of the surfaceof the filtering plate and has low cost; and the filtering plate produced with the method has firm structure.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and relates to a water filtration system, in particular to a filter plate mold used in a filter tank and a method for making a filter plate by using the filter plate mold. Background technique [0002] Generally, the filter plate of the water filtration system is poured into a special mold to form a reinforced concrete block filter plate required by the design, and then transported to the water distribution filter system in the water supply or drainage project, that is, the filter tank for installation. The installation process requires a series of processes such as leveling, cement sealing, and briquetting. The block type filter plate has the disadvantages of high cost and strict requirements on the flatness of the bottom surface of the filter plate. [0003] In order to solve the above problems, people have designed various technical solutions. For example, the Chinese patent literatur...

AI Technical Summary

Problems solved by technology

But when actually using the above-mentioned block type filter plate, there are still many deficiencies, mainly in: 1. The weight of the block type filter plate is relatively heavy, the transportation is troublesome, and it is unsafe when hoisting into the pond, and the installation efficiency is low. Low

2. Since there are many filter plates in a filter tank, there are many seams between the filter plates, which are easy to crack, resulting in air leakage, water leakage and sand leakage. During backwashing, the filter plates are even overturned, which directly affects Normal filter water supply work of the filter tank

3. Although the flatness of each filter plate can meet the requirements, the entire filter tank is composed of many filter plates, and its overall flatness cannot be guaranteed

However, when using the above-mentioned mold, there are still many defects, mainly in: 1. The formwork is not connected with the upper platen and the lower platen through the fixing parts, and both ends of the formwork can be between the above two when it is deformed under pressure. Move, thus affecting the flatness and safety of the filter plate

2. The formwork covering the entire filter tank plane is composed of large formwork and small formwork, which makes the cooperation between formwork and formwork complicated and the gaps increase

3. The outer layer of the column needs to be made of steel pipe, and the steel pipe cannot be retrieved and reused after the filter plate is formed, which may cause water pollution and increase the project cost

4. The pre-embedded seat of the filter head is only placed on the formwork, and it is easy to cause the pre-embedded seat of the filter head to deviate from its original position and tilt when pouring concrete, which increases the construction difficulty and workload

5. When installing the fixed formwork, it is necessary to support or lift the formwork and then lock the nuts, so there is a problem of difficulty in construction
