Problems solved by technology

[0002] At present, most of the filter cloth bags used for filter press filtration on the market use metal buckles with mechanical stamping and fixed structures for the hanging pile holes. Under the influence of external tension, it is easy to loosen the metal buckle from the filter cloth, shorten the service life of the filter bag, and the metal buckle of ordinary material is easy to rust in harsh environments; some manufacturers install the filter bag on the filter plate and tie it with a string The connection method is not only cumbersome to install, but also easy to loosen the rope
Due to the above important defects in the installation and filtration of the filter bag, the seller frequently replaces the filter bag for the user during the warranty period, which increases the after-sales cost of the supplier and affects the product quality reputation

Embodiment 1

[0015] Embodiment 1: with reference to attached Figure 1-5 . A filter cloth bag used for filtering a filter press, the upper edge of the filter cloth bag is a plastic buckle with a hole on the pile, the upper buckle 1 and the lower buckle 3 of the plastic buckle are filter cloth 2 and the upper buckle 1, filter cloth 2 and the lower buckle are The three buckles are bonded together by hot-melt bonding. The lower buckle 3 of the plastic buckle has a round shoulder structure with holes, and the upper buckle 1 has a circular flat pad structure with holes, and the upper and lower buckles are inlaid with filter cloth for pressure bonding. The upper buckle 1 and the lower buckle 3 of the plastic buckle are provided with protruding cusps 4 on the opposite surfaces.

Embodiment 2

[0016] Embodiment 2: On the basis of Embodiment 1, a method for forming a filter cloth bag for filter press filtration, the lower button 3 of the plastic button with a protruding shoulder is positioned through the mold, and the filter cloth bag with small holes is opened Put it on the lower button 3 of the plastic buckle with protruding shoulders and expose the lifting shoulder, then put the upper button 2 of the plastic buckle on the lifting shoulder and press the filter cloth flatly, pressurize and heat-melt through the pressurized heating equipment to make the upper and lower circles The shaped plastic buckle is bonded and fixed to the filter cloth. It is used for hanging buckle of filter cloth bag for filter press, it includes filter cloth bag made of various chemical fiber materials, round plastic buckle with protruding shoulder and plastic flat pad with opening in the middle, plastic buckle and flat pad are made of PE, PO and ABS and other raw materials; a row of small h...

Abstract

The present invention relates to a filtration cloth bag installation buckle, a filtration cloth bag for pressure filtration machine filtration, and a molding method, wherein a service life of a filtration cloth bag for pressure filtration machine filtration can be effectively prolonged and an effective use period of every set of the filtration cloth bags can be increased in the case of material, manufacture and connection fixation process change with the filtration cloth bag installation buckle, the filtration cloth bag is provided with a plastic buckle along a hanging-on-pile buckle, filtration cloth is arranged between the upper buckle and the lower buckle of the plastic buckle, and the upper buckle, the filtration cloth and the lower buckle are subjected to hot melting adhesion to form the integration. According to the present invention, the phenomenon that the filtration cloth bag hanging-on-pile buckle is easily disengaged from the filtration cloth due to external force impact in the background technology is solved, the problem of easy rusting of the metal hanging-on-pile buckle in an acid corrosion environment and an alkaline corrosion environment is solved, and the problems of tedious installation, high work intensity (including the filtration cloth bag line tying structure), low work efficiency, and the like of on-site filtration cloth bag replacement are solved.

Description

technical field [0001] The invention relates to a filter cloth bag mounting buckle for a filter press that can effectively prolong the service life of the filter cloth bag used for filtering the filter press and increase the effective utilization period of each set of filter cloth bags under the condition of changing materials, manufacturing and connection and fixing processes The invention discloses a filter cloth bag for filtering and a forming method thereof, belonging to the field of filter cloth bag manufacturing for filter presses. technical background [0002] At present, most of the filter cloth bags used for filter press filtration on the market use metal buckles with mechanical stamping and fixed structures for the hanging pile holes. Under the influence of external tension, it is easy to loosen the metal buckle from the filter cloth, shorten the service life of the filter bag, and the metal buckle of ordinary material is easy to rust in harsh environments; some ma...
