Abstract
The utility model discloses spring equipment for removing press cakes, which is used for a disc-type vacuum filter. The utility model is fixed on a beam frame above the disc-type vacuum filter. Each lower end of two support frames is provided with a pipe. A connecting rod on a blade is hung and arranged in the pipe. The guide blade is provided with a semi-annular guide head and the connecting rod. A screw rod is installed in the tab of the support frame. The screw rod is provided with a spring and a regulation nut. The utility model can cause the blade always follow a filter plate. Besides, the utility model is free from the influence of the swinging of the filter plate. The efficiency of removing press cake can reach over 90%. The nut and spring regulation mechanism can ensure the gap between the blade and a filter cloth, so the filter cloth is protected. The utility model can avoid the cutting by the blade to the filter cloth, and thus the service life of the filter cloth is prolonged.
Description
The utility model relates to a kind of elastic force and takes off the cake device, is used for disc type filter.
Coal preparation plant's floatation clean coal generally uses disc type filter at present, and it relies on compressed air to take off cake, because coal slime viscosity is big, stick to and be difficult for discharging on the filter cloth, its discharging rate only 30%, production efficiency is low, in order to finish production, the producer that has have to increase the quantity of equipment; The producer that also has adopts and manually unloads cake, has so just increased working strength of workers, and security incident also takes place easily.Homemade C603SM type disc type filter utilizes scraper to force to take off cake, finds its normal shearing filter cloth that takes place in the production, and influence is produced and normally carried out.
The purpose of this utility model is to overcome above-mentioned weak point and design a kind of elastic force of being made up of scraper plate, guiding mechanism and half-turn shape guide head and take off the cake device, mount the gap of support frame through between screw rod, nut and spring adjustable doctor and filter plate of scraper, also be provided with on the scraper and make steadily smooth mobile semi-circular guide head of scraper, discharging rate like this improves greatly, reaches more than 90%.
The utility model content, elastic force takes off the cake device by support frame, scraper, screw rod, nut, spring with semi-circular guiding is first-class forms, two support frames are loaded in the hole that is fixed on the lifting flat board on the roof beam structure of disk vacuum filter top, therebetween for being rotatably assorted, the lower end of support frame is provided with pipe, connecting rod on the scraper is mounted in the pipe, scraper is provided with semi-circular guide head and rubber-like connecting rod, in the auricle on the scaffold screw rod is installed, spring is housed on the screw rod and adjusts nut.
The semi-circular guide head that takes off the cake device also can adopt plastics or nylon material by the spring steel wire manufacturing.
The utility model advantage, (1) elastic force are taken off the cake device and are installed in disc type filter top, convenient maintenance.(2) owing to be provided with screw rod, nut and spring guiding mechanism, even there is local deformation on the filter plate surface, scraper still can be followed the tracks of filter plate all the time and change the influence that is not subjected to its beat; The semi-ring guide head cooperates the appropriate clearance that can guarantee between scraper and filter cloth with guiding mechanism, avoid shearing filter cloth.(3) do not use compressed air, avoided noise, improved environment and saved the energy yet.

Fig. 3 is the scheme of installation of the utility model on disc type filter.
Fig. 4 is the B-B cutaway view of Fig. 3
Below in conjunction with description of drawings the utility model embodiment, it is the discharging that is used for the disc type filter of coal preparation plant's floatation clean coal that elastic force takes off the cake device; In coal, water separating process, the coal slime of viscosity sticks to the filter cloth (14) of the filter plate of disc type filter and goes up (being briquette again), generally use compressed air that it is blown off, but efficient is not high, and only about 30%; Adopting elastic force to take off the cake device can improve widely and take off cake efficient; Elastic force takes off the cake device and is installed on the roof beam structure device (13), the roof beam structure device is fixed on the disc type filter housing and is positioned at its top, two support frames (3) are loaded on respectively in two holes of the lifting flat board (2) on the roof beam structure device (13), therebetween for being rotatably assorted, support frame is " opening " font, be welded into by round steel, wherein lower inside also is welded with two otic placodes (12), the round steel on support frame (3) top is contained in the hole of lifting dull and stereotyped (2), nut is installed in the outer end, to limit its axial location, respectively be welded with pipe (8) on the round steel of the both sides, bottom of support frame (3); The place, close two ends of scraper (9) is welded with rubber-like connecting rod (11), and scraper (9) is mounted on pipe (8) lining of supporting frame (3) by connecting rod (11); Be welded with the semi-circular guide head made from spring steel wire (10) on the scraper (9), when semi-circular guide head can steadily pass through during by the junction between Sector filter plate; Auricle (12) lining on the support frame (3) is equipped with screw rod (6); spring (7) is housed on the screw rod (6) and adjusts nut (4); the gap of nut (4) through between spring (7) adjustable doctor (9) and filter cloth (plate) (14) adjusted in rotation; to avoid scraper to shear filter cloth, protected filter cloth.Use the utility model to take off cake efficient and can reach more than 90%, protected filter cloth.
Claims (2)
1, a kind of scraper that comprises, main parts size such as framework take off the cake device, it is characterized in that two support frames (3) are loaded in the hole of the lifting flat board (2) on the roof beam structure that is fixed on the disc type filter top, therebetween for being rotatably assorted, the lower end of support frame (3) is provided with pipe (8), connecting rod (11) on the scraper (9) is mounted on pipe (8) lining, scraper (9) is provided with semi-circular guide head (10) and rubber-like connecting rod (11), auricle (12) lining on the scaffold (3) is equipped with screw rod (6), spring (7) is housed on the screw rod (6) and adjusts nut (4).
2, elastic force as claimed in claim 1 takes off the cake device, it is characterized in that semi-circular guide head (10) is made also by spring steel wire can adopt plastics or nylon material.
