The rotating mechanism 2 drives the knife rest 1 to intermittently rotate, so that the sludge on the surface of the filter cloth is cleaned by quickly replacing different scrapers 3, the sludge piled between the scrapers 3 and the filter cloth in the process of replacing the scrapers 3 falls along the gap between the scrapers 3 and the filter cloth, and the idle scrapers 3 are separated from the filter cloth to facilitate cleaning by cleaning staff, so that the process of replacing the scrapers 3 is effectively shortened, and the sludge scraping efficiency is greatly improved.
The rotating mechanism 2 comprises a brake motor 21, the output end of the brake motor 21 is coaxially and fixedly connected with a support shaft 22 through a connecting shaft device, two ends of the support shaft 22 are rotatably connected with bearing seats 23, and the bearing seats 23 are used for supporting the support shaft 22 and limiting the position of the support shaft 22.
Referring to fig. 1 and 2, the tool holder 1 includes a sleeve 11, the sleeve 11 is a circular tube, and the sleeve 11 are fixed to a support shaft 22. The blade holder 1 further comprises at least two blade holders 12 for mounting the doctor blade 3, which are fixed at intervals in the circumferential direction of the bushing 11. In this embodiment, two tool holders 12 are provided, and a clamping groove 121 for accommodating the scraper 3 is formed in the tool holders 12. The two tool holders 12 are symmetrically arranged about the sleeve 11 and the opening directions of the two clamping grooves 121 are arranged in parallel.
In order to improve stability between the tool holders 12 and the shaft sleeve 11, the end parts of the two tool holders 12 are fixedly connected with reinforcing plates 13, the end surface of each reinforcing plate 13 is fixedly connected with the shaft sleeve 11 at the corresponding position in the circumferential direction, and two ends of each reinforcing plate 13 are respectively fixedly connected with the two tool holders 12. And the two tool holders 12 and the two reinforcing plates 13 are fixed on the circumference of the shaft sleeve 11 in a diamond-shaped manner, so that the stability and the connection strength between the shaft sleeve 11 and the tool holders 12 are greatly improved.
The scraper 3 is a scraper made of nylon material, so that the strength of the scraper 3 is effectively ensured, and the scraper 3 is prevented from damaging filter cloth. The doctor blade 3 is slidably coupled in the clamping groove 121 and the position of the doctor blade 3 is restricted by a plurality of locking members 4. The tool apron 12 and the upper surface of the scraper 3 are in a step-by-step downward step shape, so that the probability of blocking the sludge on the upper surface of the scraper is reduced.
In this embodiment, the locking member 4 is a bolt, the locking member 4 is in threaded connection with the surface of the tool apron 12, one end of the locking member 4 extends into the clamping groove 121, and one end of the locking member 4 extending into the clamping groove 121 abuts against the side wall of the scraper 3 to compress tightly and limit the movement of the scraper 3. When the locking piece 4 is unscrewed, the scraper 3 can move along the direction of the clamping groove 121, so that the length of the scraper 3 extending out of the clamping groove 121 can be conveniently adjusted, and the scraper 3 can be conveniently and continuously scraped for cleaning the filter cloth after being worn.
The blade holder 12 has all seted up observation groove 122 along the both ends of axle sleeve 11 axis direction, and observation groove 122 and draw-in groove 121 intercommunication set up, and the length direction of observation groove 122 sets up along draw-in groove 121 opening direction. When adjusting scraper 3 position, the length that the scraper 3 is located in draw-in groove 121 can be observed through observation groove 122 to the operating personnel, and then in time suggestion operating personnel stop removing scraper 3 or renew scraper 3.
