Description

Mud discharging and cleaning assembly of filter press

Technical Field

The utility model belongs to the technical field of sludge treatment, especially, relate to a mud clearance subassembly that unloads that uses in pressure filter.

Background

The filter press is equipment for deeply dehydrating sludge by adopting a filter pressing process, the primary sludge can form a mud cake with lower water content after being dehydrated by the filter press, and the mud cake is conveyed outwards by a conveying belt during mud discharging after the filter pressing is finished. The conveyer belt is provided with a plurality of drain holes so that filtrate can be drained in time during filter pressing. Because the sludge has certain viscosity, part of sludge is inevitably adhered to the conveying belt in the filter pressing process and the sludge cake conveying process, the sludge adhered to the conveying belt is accumulated more and more along with the increase of the filter pressing times, and the sludge adhered to the conveying belt is subjected to the drying and wetting processes repeatedly, so that the sludge is adhered to the conveying belt more and more firmly, and even can block a drain hole in the conveying belt in serious conditions, and further the water content of the sludge cake obtained after the sludge filter pressing is influenced. Therefore, the sludge on the conveying belt needs to be cleaned manually at regular intervals, or the conveying belt needs to be replaced at regular intervals, the production continuity can be affected by the two modes, the production efficiency is reduced, the problem of high labor cost or high replacement cost of accessories exists, and the economical efficiency is affected.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a pressure filter that can in time clear up mud on the conveyer belt automatically unloads mud clearance subassembly.

In order to achieve the above object, the present invention adopts the following technical solutions:

the pressure filter unloads mud clearance subassembly sets up the side of sheet frame in the pressure filtering subassembly, includes: the mounting rack is connected with the plate frame, and a driving roller for driving the conveying belt to move is arranged on the mounting rack; the first supporting roller is arranged on the mounting frame and is positioned in front of the driving roller in the moving direction when the conveying belt conveys mud cakes outwards; the mud scraping knife is arranged beside the first bearing roller and is in contact with the conveying belt wound on the first bearing roller, and the mud scraping knife is parallel to the first bearing roller.

According to the above technical scheme, the utility model discloses set up at filter pressing assembly's sheet frame side and unload mud clearance subassembly, unload the mud in-process mud scraper and can scrape mud clearance to the conveyer belt around on first bearing roller automatically, can avoid the conveyer belt on the gathering of mud and the jam in hole on the conveyer belt, be favorable to reducing the moisture content of mud filter-pressing and improving the mud filter-pressing effect to can further reduce the filter-pressing time, improve filter-pressing efficiency, need not manual operation simultaneously, improve the economic nature. And through setting up first bearing roller as transition component, the mud scraper clears up the conveyer belt around on first bearing roller, rather than handling the conveyer belt around on the drive roller, can avoid the multilayer conveyer belt to coil on the drive roller after, because the conveyer belt number of piles increases and leads to the mud scraper to scrape apart from changing and lead to mud scraper to scrape the condition emergence that decreases conveyer belt or drive roller can not normally work between mud scraper and the conveyer belt.

Further, still including set up in the inboard second bearing roller of first bearing roller, second bearing roller set up in on the mounting bracket and be located the side of sheet frame, second bearing roller with first bearing roller is parallel.

Further, the first backup roller is disposed above the driving roller.

The first bearing roller and the driving roller are arranged on the mounting frame in a vertically staggered mode, so that the space occupied by the mud discharging and cleaning assembly can be reduced, and arrangement of mud scraping knives is facilitated.

Further, the position of the mud scraper on the mounting frame is adjustable.

The mounted position of mud scraper is adjustable, is convenient for adjust the distance between mud scraper and the first bearing roller, can also avoid mud scraper to scrape the damage conveyer belt when guaranteeing to scrape mud effect.

Further, still including being located the brush of first bearing roller one side, the brush pass through the rotation axis set up in on the mounting bracket and can wind the axis of rotation axis rotates, when the brush rotates with wind around the conveyer belt on the first bearing roller contacts.

The brush can scrub the conveyer belt when the conveyer belt removes, can clear up adnexed mud on the conveyer belt more thoroughly.

Furthermore, the device also comprises a high-pressure shower pipe arranged on the mounting rack.

The conveying belt is washed by the high-pressure flushing pipe, so that the sludge attached to the conveying belt can be thoroughly cleaned.

Furthermore, the high-pressure showering pipe is arranged in parallel to the width direction of the conveying belt.

The high-pressure showering pipe covers the whole width of the conveying belt and can comprehensively wash the conveying belt.
