Detailed Description
Referring to fig. 1-2, a tractor 30 for a plate-frame filter with a cleaning function comprises a vehicle body 31, wherein a driving motor, a driving wheel 32 and a driven wheel are arranged on the vehicle body 31, and the driving motor is connected with the driving wheel.
The left end of automobile body 31 upper surface articulates the lower extreme of left arm 33, wears to establish torsional spring 35 on this round pin axle, and one of two torsion arms of torsional spring 35 contacts automobile body 31 upper surface, and the other one is fixed on left arm 33, and the length of left arm 33 is greater than the distance d between the hangers of two adjacent sheet frames.
The right end of automobile body 31 upper surface articulates the lower extreme of right arm 34, wears to establish torsional spring 35 on this round pin axle, and one of two torsion arms of torsional spring 35 contacts automobile body 31 upper surface, and another one is fixed on right arm 34, and the length of right arm 34 is less than the distance d between the hangers of two adjacent sheet frames.
The drive motor of the tractor 30 is a variable frequency motor.
The working principle is as follows:
when the device is needed, the hanging lugs 12 of the two plate frames 13 are utilized to achieve the purpose of movement. When the plate frame 13 normally filters, the hangers on two sides of the plate frame 13 are lapped on the plate frame rail, and the plate frame 13 is moved by sliding the hangers on the plate frame rail.
For smooth movement, it is preferable that one tractor 30 is provided on each side of the panel frame 13.
The method specifically comprises the following steps:
in the first step, as shown in fig. 2, all the plate frames are pressed to the right side by the plate frame power equipment (generally, oil cylinders), and then the plate frame power equipment is reset, generally speaking, the first plate frame at the leftmost end is fixed on the plate frame power equipment and moves to the leftmost side together with the plate frame power equipment, which is the same as the prior art. The tractor 30 is then placed between the first and second panel frames.
In the second step, as shown in fig. 2, the two torsion arms of the tractor 30 are twisted to the maximum, the upper ends of the right mechanical arm 34 and the left mechanical arm 33 are at the highest points (hereinafter referred to as free states), and the tractor 30 moves to the left.
In the third step, as shown in fig. 3, the upper surface of the right mechanical arm 34 contacts the lower surface of the suspension loop 12 of the second plate frame, the right mechanical arm 34 is pressed by the lower surface of the suspension loop 12 (hereinafter referred to as a pressed state), the right mechanical arm 34 is turned counterclockwise, and the tractor 30 continues to move leftward.
Fourthly, as shown in fig. 4, the upper end of the left mechanical arm 33 contacts the left side surface of the lug 12 of the second plate frame, the right mechanical arm 34 is separated from the constraint of the lug 12 of the second plate frame and is located between the second plate frame and the third lug 12 to be in a free state, at this time, the input current of the driving motor of the tractor 30 reaches the limit, the driving motor of the tractor 30 reversely rotates through adjustment to start moving leftwards, at this time, the second plate frame is located between the two mechanical arms of the tractor 30, and the second plate frame is constrained by the right mechanical arm 34 to move together with the tractor 30.
In the fifth step, as shown in fig. 5, the tractor 30 is moved to the left to the cleaning position, and the tractor 30 is stopped to perform the cleaning operation. The content of the cleaning operation is referred to the prior art.
Sixthly, as shown in fig. 6, after the cleaning operation is finished, the tractor 30 continues to move left until the upper surface of the left mechanical arm 33 contacts the lower surface of the suspension loop 12 of the first plate frame, and the left mechanical arm 33 is in a squeezing state.
Seventhly, as shown in fig. 7, the tractor 30 continues to move left until the second plate frame contacts the first plate frame, at this time, the input current of the driving motor of the tractor 30 reaches the limit, and through adjustment, the driving motor of the tractor 30 rotates in the reverse direction and starts to move left, and at this time, the left mechanical arm 33 of the tractor 30 continues to be located in the squeezing state.
In an eighth step, as shown in fig. 8, the tractor 30 moves to the right, before the upper surface of the left mechanical arm 33 is separated from the constraint of the lower surface of the hanger 12 of the first plate frame, the upper surface of the left mechanical arm 33 contacts the lower surface of the hanger 12 of the second plate frame, and the left mechanical arm 33 continues to be in a squeezing state.
In the ninth step, as shown in fig. 9, the tractor 30 continues to move to the right, the left mechanical arm 33 continues to be in a free state, and the second plate frame moves to the right.
At this time, if the washing is needed to be continued, the second step to the ninth step are repeated, and if the washing is not needed to be continued, the process is ended.
See the prior art for additional details.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
