Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 2 and 3, the air shower pipe comprises a pipe body 1, one end of the pipe body 1 is sealed, the other end of the pipe body 1 is provided with a compressed air inlet 2, the surface of the pipe body 1 is provided with a horizontal binding face 3 arranged in an axial direction, the horizontal binding face 3 is provided with an axial air chamber groove 4, two ends of the axial air chamber groove 4 are sealed, and the bottom face of the axial air chamber groove 4 is uniformly provided with a plurality of air injection holes 5 communicated with the inside of the pipe body 1.
As a further improvement of the technical scheme, an included angle between the axial air chamber groove 4 and the horizontal binding face 3 is an arc angle 6. The high-pressure water which is not penetrated can be gathered to the horizontal joint surface 3 by the sliding belt to form a liquid seal, and the friction damage of the air shower pipe 7 to the rotary filter cloth 8 is almost zero.
As a further improvement of the above solution, the ratio of the total area of the gas injection holes 5 to the total area of the axial plenum grooves 4 is 5% to 40%, for example 10%, 15%, 20%, 25%, 30%, 35%, 40%. The arrangement is favorable for obtaining proper air supply capacity and air flow, effectively blows off micro-particles and water on the rotary filter cloth and does not damage the filter cloth.
As shown in fig. 1, a belt filter washer, belt filter washer is located the catch basin 9, belt filter washer includes drive roller 10, driven voller 11 and twines the rotary filter cloth 8 on drive roller 10 and driven voller 11, be equipped with in the rotary filter cloth 8 and rectify roller 12, turn to roller 13 and tensioning roller 14, still include wind and drench pipe 7, be equipped with backing roll 15 between turn to roller 13 and the drive roller 10, wind drenches pipe 7 and sets up between backing roll 15 and turn to roller 13, wind drenches 4 openings in axial air chamber groove 7 downwards, the horizontal binding face 3 of wind drenches pipe 7 and laminates mutually with rotary filter cloth 8's internal surface.
As a further improvement of the above technical solution, a high-pressure water injection pipe 16 is arranged between the support roller 15 and the drive roller 10 and above the rotary filter cloth 8.
As a further improvement of the above technical solution, a scraper 17 for scraping the material on the rotary filter cloth 8 is arranged outside the driving roller 10.
As a further improvement of the technical scheme, a tensioning cylinder 18 is arranged at the inner bottom of the belt type filtering and washing machine, and the tensioning roller 14 is installed at the front end of a piston rod of the tensioning cylinder 18.
As a further improvement of the above technical solution, the length of the axial air chamber slot 4 is greater than the working width of the rotary filter cloth 8 and less than the actual width of the rotary filter cloth 8. So that the compressed air ejected from the air ejecting holes 5 is homogenized into a strip-shaped air curtain in the axial air chamber groove 4, and then the two ends of the air curtain do not leak. The working width of the rotary filter cloth 8 is the width of the slurry uniformly sprayed on the rotary filter cloth 8.
In a specific embodiment, as shown in fig. 1, during the operation of the belt filter washer, the slurry containing powder is uniformly sprinkled on the rotary filter cloth 8 traveling at a constant speed from the slurry inlet distributor, the rotary filter cloth 8 is driven by the driving roller 10, and a closed transmission chain is completed through the deflecting roller 13, the tensioning roller 14 controlled by the tensioning cylinder 18, the rectifying roller 12 and the driven roller 11. In the process, the washing liquid is sleeved with the powder in the slurry liquid along the multi-stage liquid distribution pipe in a countercurrent manner, and the washing liquid is sucked into the multi-stage liquid return pipe by the vacuum sucker group arranged on the back surface of the rotary filter cloth 8 (countercurrent sleeving washing is that fresh washing liquid is uniformly sprinkled on the rotary filter cloth 8 traveling at a constant speed from the right side (discharge end) of the figure and is sleeved with the powder on the left side (feed end) in sequence through the vacuum sucker group). The cleaned and initially sucked-up material is scraped off to a silo by a scraper 17. The filter cloth is then continuously backwashed by high-pressure water jet pipes 16. The horizontal binding face 3 laminating that gyration filter cloth 8 is comparatively inseparable drenches pipe 7 with wind is in the same place, compressed air enters into in the wind drenches pipe 7 from compressed air inlet 2, 5 spun compressed air homogenization of fumarole is long banding air curtain in axial air chamber groove 4, the working width that air curtain length covered gyration filter cloth 8 nevertheless is less than gyration filter cloth 8 actual width, guarantee that the air curtain both ends do not run out of gas, axial air chamber groove 4 is arc angle 6 with the contained angle of horizontal binding face 3, the high pressure water that does not pierce through can be by the draw runner and gather horizontal binding face 3 department and form the liquid seal, make the wind drenches pipe 7 and almost be zero to the frictional damage of gyration filter cloth 8. Because the penetrability of compressed air to the rotary filter cloth 8 is far stronger than that of high-pressure water, and the working width of the rotary filter cloth 8 is fully covered by the strip-shaped air curtain and is smaller than the actual width of the rotary filter cloth 8, microparticles remained in the rotary filter cloth 8 are blown off by all the water-connecting materials effectively, the implementation and application effects are very remarkable, the production period is shortened, and the service life of the rotary filter cloth 8 is prolonged by more than ten times.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
