Problems solved by technology

Most of this kind of equipment uses rigid filter material, such as stainless steel plate with micro-holes or stainless steel wire filter. The structure design is better in the cleaning and cleaning of the filter, but the work is cumbersome and the requirements are relatively high when replacing the filter. High, especially the use of scraper-type slag removal device is easy to damage the rigid filter screen; in addition, the follow-up treatment of the filter residue discharged from the sewage outlet is still not solved
[0006] None of the above types of filter bag filters can solve the contradiction between filtration and filter residues well, especially the fluid filter residues discharged from the sewage outlet increase the difficulty of subsequent treatment, and the assistance of subsequent treatment equipment is needed to Solve the problem of filter residue

Abstract

The invention discloses a filter with squeezing filtering bags. The filter comprises a barrel (1), an upper sealing head, a lower sealing head, an exhaust port (6), a feeding port, a discharging port, a squeezing media inlet and a squeezing media outlet and is characterized in that at least one filtering squeezing device is arranged in the barrel (1), a rigid pipe (13) provided with a through hole (16) is connected between an upper hole plate (10) and a lower hole plate (21) of each filtering squeezing device, a squeezing flow guide film (14) provided with the filtering bag (15) inside is connected into each rigid pipe (13) through an upper squeezing diversion film fixing part (11) and a lower squeezing diversion film fixing limit part (18) distributed with through holes, and an upper squeezing flow guide film limit part (12) distributed with through holes is arranged on the upper portion of each filtering squeezing device. The filter can automatically and continuously operate to perform cleaning of a filter screen and squeezing fluid exhaustion of filter slag in the filtering bags, squeezed filter slag dry cakes are retained in the filtering bags, the filtering bags are simple and convenient to replace, trouble of fluid-state filter slag pollution is avoided, and the filter is strong in applicability, large in unit area filtering amount of the filtering bags and low in operation cost.

Description

[0001] Technical field: [0002] The invention relates to a filter bag filter, in particular to a squeeze filter bag filter. technical background: [0003] The current filter bag filter mainly has the following types: [0004] 1. Single-bag or multi-bag filter, in the principle of filtration, the filter bag is fixed inside the open filter support tube, the liquid to be filtered enters from the inside of the filter bag, and the liquid filtered by the filter bag flows out of the filter bag , the particulate matter is trapped inside the filter bag, and the particulate matter together with the filter bag is taken out from the perforated filter support tube when the filter bag is replaced. At present, the single-bag and multi-bag filters are consistent in structure, but the filtration area and processing capacity of the equipment are increased by increasing the number of filter bags in the filter bag. This type of filter is troublesome when replacing the filter bag. First, t...
