Abstract

The utility model discloses a filter for coal slurry, including outer barrel, the top sets up the feed inlet, and the below sets up the discharge gate, is equipped with a screen cloth section of thick bamboo in the outer barrel, is equipped with in the screen cloth section of thick bamboo and cleans and scrapes the brush, cleans and scrapes the brush and utilize the pivot to connect the driving motor at outer barrel top, and outer barrel bottom is equipped with an inverted cone and stores the sediment fill, is equipped with the agitator in the sediment fill, stores the sediment fill bottom and connects the sediment bucket, is provided with a diaphragm type manometer and diaphragm relief valve on the cover at outer barrel top, and the diaphragm relief valve passes through the pipe connection and arranges the thick liquid pipeline. The utility model has the advantages of reasonable design ingenious, clean and scrape the brush and scrape the large granule that filters off on the screen cloth section of thick bamboo and brush, get into the storage sediment fill to fall into a storage sediment section of thick bamboo, under the circumstances that the filter does not shut down, discharge the slag charge, when outer barrel internal pressure is too big, the diaphragm safety valve is opened, and the leading-in row's thick liquid pipeline of thick liquids that will overflow reduces the pressure in the outer barrel, avoids the device to damage.

Description

Filter for coal water slurry

Technical Field

The utility model relates to a filter for coal slurry.

Background

The coal water slurry is ground by the ball mill and then filtered, impurities with larger particles are filtered out, the fineness of the coal water slurry is guaranteed, certain pressure exists in the tank body when the filter operates, if a filter screen of the filter is blocked by large particles, the coal water slurry in the filter cannot be smoothly discharged, the pressure in the tank body is continuously increased, the excessive pressure can cause damage of a screen cylinder, and meanwhile, the coal water slurry can be sprayed out from a gap of a cover plate under the condition that no discharge way exists, so that the environment of a factory building is polluted.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a filter for the coal slurry, the filter screen of solving in the jar body when guaranteeing the filter effect blocks up the pressure release problem when causing pressure too big, avoids the coal slurry to spill over and the damage of device.

To achieve the purpose, the utility model adopts the structure that: the utility model provides a filter for coal slurry, includes outer barrel, the outer barrel outside sets up the support and is used for fixed outer barrel, and outer barrel top side sets up the pan feeding mouth, and the below side sets up the discharge gate, be equipped with a screen cloth section of thick bamboo in the outer barrel, be equipped with in the screen cloth section of thick bamboo and clean and scrape the brush, outer barrel top sets up the cover, and an inverted cone stores the sediment fill is connected to the bottom, is equipped with the agitator in storing the sediment fill, the agitator is scraped with cleaning and is brushed the transmission motor who connects the cover and go up the setting through the pivot, be equipped with on the cover and wash mouth, diaphragm type manometer and diaphragm relief valve, the diaphragm relief valve passes through pipe connection mud pipe way.

The lower part of the slag storage hopper is connected with a slag storage barrel through an upper valve, and the bottom of the slag storage barrel is provided with a lower valve.

The beneficial effects are as follows: the utility model has the advantages of reasonable design ingenious, clean and scrape the brush with the screen cloth section of thick bamboo on the large granule that filters off get off, get into the storage sediment fill to in falling into a storage sediment section of thick bamboo, under the circumstances that the filter does not shut down, discharge the slag charge. When the pressure in the outer cylinder body is overlarge, the diaphragm safety valve is opened, overflowed slurry is guided into the slurry discharge pipeline, the pressure in the outer cylinder body is reduced, and the device is prevented from being damaged.

Drawings

The invention will now be described, by way of example, with reference to the accompanying drawings, in which:

fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

The filter for the coal water slurry comprises an outer barrel 3, wherein a support 11 is arranged on the outer side of the outer barrel 3 and used for fixing the outer barrel, a feeding port 12 is arranged on the side surface above the outer barrel 3, a discharging port 14 is arranged on the side surface below the outer barrel 3, a screen cylinder 4 is arranged in the outer barrel 3, a cleaning scraping brush 5 is arranged in the screen cylinder 4, a barrel cover 2 is arranged on the top of the outer barrel 3, an inverted cone-shaped slag storage hopper 6 is connected to the bottom of the outer barrel, a stirrer 7 is arranged in the slag storage hopper 6, the stirrer 7 and the cleaning scraping brush 5 are connected with a transmission motor 1 arranged on the barrel cover 2 through a rotating shaft, a flushing port 13, a diaphragm type pressure gauge 9 and a diaphragm safety valve 10 are arranged on the barrel cover 2, and the diaphragm safety valve 10 is connected with a slurry discharge pipeline through a pipeline.

The lower part of the slag storage hopper 6 is connected with a slag storage cylinder 8 through an upper valve 15, and the bottom of the slag storage cylinder 8 is provided with a lower valve 16.

The utility model has the advantages of reasonable design ingenious, clean and scrape the brush with the large granule that filters off on the screen cloth section of thick bamboo and get off, get into the storage sediment fill to fall into a storage sediment section of thick bamboo, set for certain time about the storage sediment section of thick bamboo, to the time after, go up the valve and open, lower valve is closed, makes the slag charge in the storage sediment fill fall into in the storage sediment section of thick bamboo, then closes the valve, opens lower valve, under the circumstances that the filter does not shut, discharges the slag charge. The diaphragm relief valve with when outer barrel internal pressure is too big, the diaphragm relief valve opens, and the thick liquids that will overflow are leading-in arranges the thick liquid pipeline in, reduce the pressure in the outer barrel, avoid the device to damage.

The present invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification, and to any novel method or process steps or any novel combination of features disclosed.
