Abstract

The utility model is a horizontal self-washing filter which is characterized in the reversed-washing piston and filtering core installed on the hollow spindle in the filtering machine shell formed by the tank, the front cover and the back cover. The reversed-washing piston comprises a left piston, a right piston, a connecting sleeve, a sealed ring and a sealed sleeve. Two sealed rings are arranged on the piston at each terminal. The sealed rings are in correspondence with the inner hole of the filtering drum on the filtering core. A thread bar is installed on the lower part of the right piston to push the anti-piston movement. The thread bar is communicated with the deceleration device through torque limiter. Trip limiter is arranged in the front and at the back of the filtering machine shell. Because of the revered-washing piston and the filtering core installed in the filtering machine shell, and the trip limiter arranged in the front and at the back of the filtering machine shell, the revered-washing piston can repeatedly rinse the filtering net and drain out the residue if jamming of sundries happens, so that the filtering machine can do continuous work for a long time.

Description

Horizontal from the washing and filtering machine

Technical field

The utility model relates to technical field of chemical, particularly a kind of being used for smart filter horizontal from the washing and filtering machine of alkaline medium.

Background technology

The stoste of chemical fibre factory is filtered the main flame filter press that adopts at present, because flame filter press does not have from flushing process, so its filter screen will be changed once in about two to three days, every replacing primary filter screen need stop production 3 hours, and operating personnel's labour intensity is very big, influences the output of stoste.

Technical scheme

The purpose of this utility model provides a kind of the horizontal from the washing and filtering machine of self-cleaning foreign material, continuous operation that have.

The utility model is to realize like this, it is characterized in that in the filter housing that constitutes by tank body, protecgulum and bonnet, being provided with backwash piston and the filter core that is sleeved on the hollow shaft, the backwash piston is made of left piston, right piston, coupling sleeve, sealing ring and seal sleeve, two sealing rings are arranged on the piston of every end, filter drum endoporus on sealing ring and the filter core is slidingly matched, the screw that can promote anti-piston walking is housed in right lower part of piston, leading screw links to each other with the deceleration unit by torque limiter, in the front and back end of filter housing stroke limiting stop is installed.

The utility model is owing to be provided with backwash piston and filter core in the filter housing, front and back end at the filter casing is equipped with stroke limiting stop, like this in case the foreign material clogging takes place, the backwash piston will wash repeatedly to filter screen, and filter residue discharged outside the machine, thereby realize the long continuous operation of filter.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described;

Fig. 1 is horizontal structural representation from the washing and filtering machine,

Fig. 2 is a backwash structure of piston schematic diagram,

Fig. 3 is the structural representation of filter core.

The specific embodiment

As Figure 1-3, this is horizontal to comprise tank body 1 from the washing and filtering machine, protecgulum 2, bonnet 3, hollow shaft 4, left piston 11, right piston 12, coupling sleeve 13, sealing ring 14, sealing shroud 19, torsion spring 15, filter drum 21, filter screen 16, protecting wire net 17, leading screw 8, screw 22, turn round limiter 20, deceleration unit 10, stroke limiting stop 18 and supporting seat 7, by tank body 1, be provided with backwash piston 6 and the filter core 9 that is sleeved on the hollow shaft 4 in the filter housing that protecgulum 2 and bonnet 3 constitute, backwash piston 6 is by left piston 11, right piston 12, coupling sleeve 13, sealing ring 14 and sealing shroud 19 constitute, two sealing rings 14 are arranged on the piston of every end, filter drum endoporus on sealing ring 14 and the filter core 9 is slidingly matched, the screw 22 that can promote 6 walkings of backwash piston is housed in the bottom of right piston 12, leading screw 8 links to each other with deceleration unit 10 by torque limiter 20, in the front and back end of filter housing 5 stroke limiting stop 18 is installed, filter core 9 is by filter drum 21, filter screen 16 and protecting wire net 17 constitute, wherein the precision of filter screen is the filter felt of 25 μ, and described filter drum 21 is exactly a skeleton of often saying filter screen; Operation principle is when foreign material stop up the filter opening on the filter screen, 6 work of backwash piston, under the backwash operating mode, communicate with mud hole by three holes on the hollow shaft, when the extreme position of two ends, the backwash that quits work of three holes on the stifled letter of the sealing shroud 19 at the branch sleeve 13 two ends hollow shafts, filter, screw 22 is equipped with in right piston 12 bottoms, when leading screw 8 rotations, utilize screw to promote 6 walkings of backwash piston; When the backwash piston walks to two terminal points, touch 18 of stroke limiting stops and send instruction near switch, motor is returned, backwash piston 6 is oppositely walked, and realizes automatic backwash work and so forth.

Claims

1, a kind of horizontal from the washing and filtering machine, it is characterized in that in the filter housing that constitutes by tank body, protecgulum and bonnet, being provided with backwash piston and the filter core that is sleeved on the hollow shaft, the backwash piston is made of left piston, right piston, coupling sleeve, sealing ring and seal sleeve, two sealing rings are arranged on the piston of every end, filter drum endoporus on sealing ring and the filter core is slidingly matched, the screw that can promote anti-piston walking is housed in right lower part of piston, leading screw links to each other with the deceleration unit by torque limiter, in the front and back end of filter housing stroke limiting stop is installed.

2, root a tree name claim 1 is described horizontal from the washing and filtering machine, it is characterized in that filter core is made of filter drum, filter screen and protecting wire net, and wherein the filter screen precision is the filter felt of 25 μ.
