Description

Filter for chemical production

Technical Field

The utility model relates to a chemical industry technical field especially relates to a filter for chemical production.

Background

In the production process of chemical products, two or more chemical materials may react together to generate precipitate, flocculent, reaction residue, etc., and a new product after the reaction is usually filtered before the subsequent processing, so as to separate the liquid reactant from the reaction residue. Most of the existing filters adopt fixed filter plates and filter elements for filtering, solid-liquid chemical mixtures flow on the filter plates to leave chemical residues on the filter plates, and when more solid-liquid chemical mixtures exist, a large number of filter residues block holes of the filter plates, so that the filter plates are blocked, the effective filtering capacity of the filter plates is influenced, and even the filter plates are completely blocked, so that normal filtering cannot be performed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a filter for chemical production.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a filter for chemical production, includes fixing base and lower fixing base, the inlet pipe is installed at the top of going up the fixing base, motor and negative pressure pipe are installed to the bottom of fixing base down, go up the fixing base and be connected with the filtration screen panel down between the fixing base, go up the fixing base, filter the screen panel and constitute cylindrical filtration cavity with lower fixing base, the end connection of negative pressure pipe has the negative pressure cover, the negative pressure cover is located the bottom of filtering the cavity, be connected with the pivot on the power shaft of motor, the pivot is located the inner chamber of filtering the cavity, the outer wall of pivot is the heliciform and is provided with stirring vane.

Preferably, the outer wall of the rotating shaft is provided with a fixing support, the outer wall of the fixing support is bonded with a scraper, and the scraper is in contact with the inner wall of the filter screen.

Preferably, the filter screen panel is bilayer structure, it has the filter pulp to filter to fill in the inner chamber of screen panel, the last through-hole of having seted up of filter pulp, it is provided with fastening bolt to alternate in the through-hole, fastening bolt's both ends pass upper fixing base, lower fixing base respectively and fasten through the nut.

Preferably, the upper side and the lower side of the filter screen cover are both bonded with sealing rubber pads, and the fastening bolts penetrate through the sealing rubber pads.

The utility model provides a filter for chemical production, beneficial effect lies in: through setting up motor and negative pressure hood, drive stirring vane by the motor, scraper blade and fixed bolster rotate, can strike off remaining the material that filters the screen panel inner wall when the scraper blade rotates, avoid filtering the screen panel and take place to block up the normal use that influences the filter, the material suction that will strike off is managed by negative pressure simultaneously and communicates outside negative pressure equipment, can effectually avoid the inside too much large granule material of gathering of filter, guarantee the long-time normal use of filter, improved filtration efficiency.
