The first sieve plate 101 is coaxially distributed and fixedly connected with the main shaft 102, the top end of the main shaft 102 is arranged above the first sieve plate 101 and connected with the first driving part 103, and the first driving part 103 is a motor and the like and is used for driving the main shaft 102 to rotate positively and negatively so as to drive the first sieve plate 101 to rotate relative to the sieve cylinder 1; the first driving member 103 is connected to the screen cylinder 1 or an external bracket, and in this embodiment, the first driving member 103 is connected to the screen cylinder 1 via a link or the like.
In order to facilitate clearing the material blocking the first sieve plate 101, in this embodiment, an air injection groove 2 is arranged below the first sieve plate 101, the top end of the air injection groove 2 is of an open structure, and the top of the air injection groove is attached to the bottom of the first sieve plate 101; meanwhile, the inner cavity of the air injection groove 2 is connected with an external air source 202 through a high-pressure pipe 203; the external air source 202 is used for supplying high-pressure air into the air jet tank 2 through the high-pressure pipe 203 so as to impact the meshes on the first sieve plate 101, and the plugs therein are blown upwards.
In order to avoid splashing of the plugs blown up from bottom to top, in this embodiment, the diversion channel 3 is arranged above the first sieve plate 101; the diversion channel 3 has two ends, which are n-shaped as a whole, and the two ends are respectively an end part one 301 and an end part two 302.
In order to avoid splashing of the plugs and to fully utilize the high-pressure air flow, in this embodiment, the first end 301 and the second end 302 are attached to the top of the first sieve plate 101, and the top projection of the first end 301 coincides with the top projection of the top end of the air injection groove 2; that is, the cross-sectional shapes of the two are the same, so that the air flow ejected from the top end of the air injection groove 2 can enter the end part two 302 after passing through the first sieve plate 101, and the corresponding blockage can also enter the inner cavity of the diversion channel 3 and be guided to the end part two 302.
In order to prevent the high-pressure air flow from rushing the blockage in the diversion channel 3 into the first sieve plate 101 again, a first sieve plate 303 is arranged in the second end part 302, the aperture of the first sieve plate 303 is smaller than that of the first sieve plate 101, so that the blockage is left in the first end part 301, the high-pressure air flow impacts the first sieve plate 101 from top to bottom, the high-pressure air flow is fully utilized, and the first sieve plate 303 is cleaned again.
In order to fully clear the first sieve plate 101, in this embodiment, the actuating end of the second driving member 201 is further connected to the outer walls of the air injection groove 2 and the air guide channel 3, respectively, so as to drive the air injection groove 2 and the air guide channel 3 to reciprocate in the radial direction of the first sieve plate 101.
The second driving part 201 is a structure such as a telescopic cylinder, which can realize linear reciprocating motion, and drives the air injection groove 2 and the diversion channel 3 to reciprocate on one diameter of the first sieve plate 101, so as to prevent plugs in the diversion channel 3 from falling into the sieve cylinder 1, and further enable the first end 301 and the second end 302 to be distributed along the circumferential direction of the first sieve plate 101.
Working principle:
In operation, the external air source 202, the first driving member 103 and the second driving member 201 are synchronously opened. The second driving part 201 drives the air injection groove 2 and the flow guide channel 3 to reciprocate in the radial direction of the first sieve plate 101, in the movement process, the first driving part 103 drives the first sieve plate 101 to rotate through the main shaft 102, the rotation direction is the direction of the first end 301 towards the second end 302, then the mixture composed of lubricating oil and scraps is poured on the first sieve plate 101, the mixture with large particle size is remained on the first sieve plate 101, the later cleaning is carried out, the cooling liquid passes through the first sieve plate 101 and flows into the sieve cylinder 1, and part of scraps can block the screen mesh in the process; in the process of the reciprocating motion of the first driving part 103, the high-pressure air generated by the external air source 202 flows through the top end of the air injection groove 2 towards the first sieve plate 101, so that the blocking objects in the part, impacted by the air flow, of the first sieve plate 101 can be blown into the first end 301 arranged above the air injection groove 2, enter the first end 301, are wrapped by the high-pressure air flow entering the first end 301 and flow towards the second end 302, are blocked in the diversion channel 3 by the first sieve plate 303 on the second end 302, and continuously impact the first sieve plate 101 from top to bottom after passing through the first sieve plate 303, so as to clear the blocking operation of the first sieve plate 101; when the blockage in the diversion channel 3 is full, the diversion channel can be removed and cleaned in time; wherein the high pressure tube 203 performs an adaptive motion along with the motion of the second driver 201.
In the above process, the air flow firstly impacts the first sieve plate 101 from bottom to top, so that the blockage in the first sieve plate 101 can be effectively removed and collected in the diversion channel 3, then the high-pressure air flow is guided by the diversion channel 3, and then impacts the first sieve plate 101 from top to bottom, thereby realizing effective blockage removal of the first sieve plate 101, and being performed in the working process of the first sieve plate 101, avoiding the defect of suspending the first sieve plate 101 for blockage removal and improving the recovery efficiency of the cooling liquid.
Secondly, in the above process, the rotation direction of the first sieve plate 101 is from the first end 301 to the second end 302; that is, the part of the first sieve plate 101 after being cleaned by the high-pressure airflow from bottom to top is cleaned again by the high-pressure airflow from top to bottom, thereby avoiding the defect that large-particle plugs fall into the sieve cylinder 1; the rotation of the first sieve plate 101 allows the mixture of cooling liquid and waste to be spread evenly on the first sieve plate 101, thereby avoiding the disadvantage of concentrated accumulation.
