Abstract
The present invention relates to a belt type vacuum filter which is composed of a main tank body, an inclined bearing body, a belt type filtering and driving device, a vacuum chamber, a soiling liquid cavity, a liquid purifying tank, a water pump, a water blaster, a butterfly valve, a pressure sensor, a liquid level device, an oil and water separator, an oxygen generator, an electric device controlled by a PC, etc. The present invention has large filtering area, nearly equal bottom area with that of the soiling liquid cavity, adjustable vacuum degree, large flow quantity, high efficiency, easy establishment of a press cake layer, high filtering precision, administration cost saving and high automatization degree, and is suitable for filtering and purifying industrial cooling and lubricating emulsion, oil liquid, water and other soiling liquid.
Description
The invention belongs to the filtering and purifying of industrial cooling and lubricating emulsion, fluid, water and other soiling solutions.
It is low that existing magnetic filter device exists filtering accuracy, can not filter the shortcoming of nonferromagnetic impurity.Existing gravity filter device exists the low shortcoming of filter efficiency.The shortcoming of existing rotary drum vacuum apparatus is: 1. adopt the induced draft blower withdraws vacuum noise big, power consumption is big, and vacuum can not be regulated.2. the soiling solution control is located at the bottom of filter, and sediment is many in the chamber, and difficulty is cleaned in blowdown, and the liquid of discharging in the dirt is many; Because deposit is on the increase in the chamber, new pollution sources will be formed.3. be difficult for setting up cake layer.Since filter material only envelope in the part of rotary drum, and with the motion campaign of rotary drum.So constantly fallen by the influence of gravity attached to the bulky grain dirt on the surface of filter medium, filtering accuracy is difficult to improve, and the filter material that consumes is many.4. filter area is only relevant with the sectional area of rotary drum immersion soiling solution part, so filter area is little, flow is little, inapplicable large tracts of land, the concentration filter of big flow.5. because of no oil removing, oxygen-increasing device, the service life of cooling-lubricant is low, and 6. pipeline is rigidly connected, and easily causes vibrations, and noise is big.7. electrical control function imperfection.
The objective of the invention is to avoid weak point of the prior art, and provide a kind of flow big, efficient height, management cost are economized.The filtering accuracy height has and can realize automatic working cycle.The filter of functions such as warning.
Purpose of the present invention can take following measure to reach:
1. the fuselage of filter is made up of main box and inclined bearing body.Adopt between main box and the inclined bearing body to be rigidly connected, angle between the two is the obtuse angle; Reducing gear is equipped with in the top of inclined bearing body, bearing-surface upper support filter material and the scraper chain that links to each other with reducing gear; The height of inclined bearing body is so that the liquid in the dirt that is excluded is back in the soiling solution chamber effectively is advisable.
2. belt filter.The belt filter is made up of filter material, screen, scraper chain etc.The filter material filtration; Screen mainly plays supporting and filtration; Scraper chain mainly plays the blowdown effect.In soiling solution tank, filter material is flat between screen and the scraper chain, and its top is the soiling solution chamber, and its below is a vacuum chamber.Like this, the filter area of filter is big, and almost the floor space with the soiling solution chamber equates, filtration yield is big, and cake layer is easily set up, and can improve filtering accuracy.Filter material and scraper chain also place on the inclined bearing face, and during blowdown, filter material and scraper chain move towards oblique upper along inclined bearing, and dirt is sent into dirt box.
3. tape drive mechanism.The same reducing gear of tape drive mechanism, scraper chain, pressure sensor.Compositions such as butterfly valve.Vacuum during filter work can reflect by pressure sensor, but the operating pressure of regulating the pressure controlled filter machine of pressure sensor.In filter when work,, when the dirt on the filter material deposits to after certain thickness, vacuum reach predetermined value, pressure sensor is connected butterfly valve and is opened, and the clean liquid in the clean liquid case is back in the vacuum chamber, reduces vacuum, prepares for reducing gear starts.After having crossed certain hour (adjustable), butterfly valve cuts out, and the reducing gear action drives scraper chain and filter material.Dirt moves a certain distance (adjustable) through the inclined bearing face, and dirt is sent into dirt box.This just can not produce new pollution sources.
4. vacuum chamber is located at the bottom of filter, and the soiling solution chamber is positioned at the top of vacuum chamber, and the centre is separated by filter; Soiling solution is provided with oil water separator in the chamber; Be provided with liquid level meter in the pipeline that bottom the soiling solution chamber, communicates; Clean liquid case is located at the top of filter, on the clean liquid case return duct that communicates with vacuum chamber is housed, and butterfly valve is housed on the return duct, and an end of filter is provided with water pump, and the water pump trunk line is connected with vacuum chamber.The interface of water pump trunk line connects with the pliability connecting hose; Pump outlet is provided with automatic aerator; Water sprayer is in succession on the trunk line of water pump, the arm of water sprayer simultaneously and vacuum chamber, oil water separator plays the effect of oil removing skimming.Liquid level meter can reflect the height of liquid level, and clean liquid case plays the heat radiation cooling and replenishes clean liquid effect to vacuum chamber.Water pump, water sprayer play clean liquid of extraction and aspiration vacuum effect, and its noise is little, and the pliability connecting hose plays the damping and silencing effect.Automatic aerator can increase the oxygen content in the clean liquid, reduces the harm of anaerobic bacteria, prolongs the service life of cooling-lubricant.
5. pressure sensor.Liquid level meter, reducing gear, butterfly valve, pump motor, coiled strip device, automatic aerator connect with PC respectively, can realize automatic demonstration, warning and automatic working cycle.
The present invention compared with prior art has following advantage:
1. flow is big, and applied range both can filter ferromagnetism impurity and also can filter nonferromagnetic impurity; Both can be used for unit and filtered, also can be used for the multimachine concentration filter.
2. filtering accuracy height, noise is little.
3. administrative expenses are economized.Used filter material amount is few; The long service life of cooling-lubricant; Be convenient to the cleaning maintenance, reduce and shut down number of times.
4. automatic degree height has more perfect acousto-optic warning system, and entire work process is controlled by PC, can realize automatic working cycle, shows automatically, reports to the police.
