Description

TECHNICAL FIELD

[0001] The utility model relates to a filter, especially a color paint tubular filter. BACKGROUND

[0002] In the production and application process of liquid materials such as color paint and coating, filtration is an important step to ensure product quality and performance. Color paint tubular filter is a device used to filter impurities in oil paint, coating and other liquids to ensure the purity and quality of the final product. This type of filter is usually composed of a tubular structure, which contains one or more layers of filter cartridges or filter screens of different materials and fineness inside. When the color paint passes through these filter layers, larger particles, impurities and insoluble substances are trapped on the filter cartridges, while the relatively pure color paint continues to flow. Color paint tubular filter is widely used in the production process of paint, ink, varnish and other related industries, and is essential to ensure product quality.

[0003] The filter screen in the existing color paint tubular filter is prone to clogging after long-term use, resulting in reduced filtration efficiency. When replacing or cleaning the filter screen, the machine needs to be stopped, increasing maintenance cost and time.

[0004] Therefore, it is necessary to design a color paint tubular filter that facilitates the replacement and cleaning of the filter screen. SUMMARY

[0005] The technical scheme is as follows: a color paint tubular filter, comprising a pipeline, the pipeline end is provided with a communication joint, the pipelines are communicated through the communication joint, the two sides of the communication joint are symmetrically provided with a rodless sliding rail, a filter frame is movably arranged between the rodless sliding rails, the two sides of the filter frame are provided with sliding blocks and are slidably connected with the rodless sliding rails, two filter screens are horizontally and symmetrically arranged in the filter frame, the filter frame is arranged between the communication joints, at least one filter screen is arranged at the communication position of the two communication joints, and the liquid flows into the pipeline cavity connected therewith after being filtered by the filter screen.

[0006] Optionally, the outer wall of the symmetrically two sides of the filter screen is fixedly connected with a pinion, the pinion passes through the filter frame and is arranged outside the filter frame, and the two ends of the rodless sliding rail towards the filter frame are provided with a rack engaged with the pinion. When the filter frame moves horizontally to the position where the rack and the pinion are engaged, the pinion rotates with the horizontal movement of the filter frame to turn over the filter screen.

[0007] Optionally, the inside of the filter frame gradually inclines downward towards the direction of the filter screen with the center point as the center. This design is conducive to the smooth flow of liquid to the filter screen and reduces the possibility of residual retention in the filter frame.

[0008] Optionally, the input pipe is symmetrically provided with a fixing frame on both sides, a cleaning liquid input pipe is installed on the fixing frame, a spray head is rotatably connected to the end of the cleaning liquid input pipe, and spray holes are arrayed on the spray head.

[0009] Optionally, the spray head is arrayed with cleaning rods on one side of the spray holes.

[0010] Optionally, a motor is installed on the fixing frame, a gear set is arranged between the spray head and the motor output shaft, and the motor rotating power is transmitted to the spray head through the gear set to drive the spray head to rotate.

[0011] Optionally, a fan blade for dispersing color paint is rotatably arranged on the filter screen.

[0012] The beneficial effects of the utility model are as follows: 1. The filter frame moves horizontally along the rodless slide rail to realize the function of seamlessly replacing the filter screen, reduce downtime caused by replacing the filter screen, and the process is convenient and efficient.

[0013] 2. After the filter frame moves horizontally along the rodless slide rail to mesh with the rack and pinion, the rack drives the pinion to rotate with the further horizontal movement of the filter frame, thereby driving the filter screen to overturn 180 degrees, effectively removing the accumulated impurities on the filter screen, preventing blockage and improving the filtering efficiency.

[0014] 3. The motor drives the spray head to rotate through the gear set, thereby realizing the relative movement of the cleaning rod and the filter screen, combining the cleaning liquid sprayed by the spray head, and realizing the function of multi-angle and thorough cleaning of the filter screen.

Detailed Implementation

[0022] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0023] Example: A colored paint tube filter, such as Figures 1-3 As shown, the system includes a pipe 1, a rodless slide rail 2, a slider 3, a filter frame 4, and a filter screen 5. A connecting joint 101 is provided at the end of the pipe 1, connecting the pipes 1 together. Rodless slide rails 2 are symmetrically arranged on both sides of the connecting joint 101, and a filter frame 4 is movably arranged between the rodless slide rails 2. Slider 3s are provided on the outer walls of the filter frame 4 on both symmetrical sides, and the filter frame 4 is slidably connected to the rodless slide rails 2 via the slider 3s. Two filter screens 5 are symmetrically arranged laterally within the filter frame 4, and the filter screens 5 are used to filter impurities in the liquid. The two filter screens 5 are designed for seamless replacement by moving the filter frame 4. The filter frame 4 is located between the connecting joints 101, and at least one filter screen 5 is located at the connection point of the two connecting joints 101. After the liquid enters from the input pipe 1, it is filtered by the filter screen 5 and flows into the inner cavity of the pipe 1 connected to it. The inner side of the filter frame 4 gradually slopes downward towards the filter screen 5 with the midpoint line as the center. This design facilitates the smooth flow of liquid to the filter screen 5 and reduces the possibility of residue remaining in the filter frame 4.

[0024] like Figure 2 and Figure 3 As shown, small gears 6 are fixedly connected to the outer walls of the symmetrical sides of the filter screen 5. The small gears 6 pass through the filter frame 4 and are located on the outside of the filter frame 4. The rodless slide rail 2 has racks 7 at both ends facing the filter frame 4 that mesh with the small gears 6. When the filter frame 4 moves horizontally until the racks 7 mesh with the small gears 6, the small gears 6 rotate with the horizontal movement of the filter frame 4 to drive the filter screen 5 to flip. The filter screen 5 flips at an angle of 180 degrees. By flipping the filter screen 5, the accumulated impurities on the filter screen 5 are removed.

[0025] like Figure 4 and Figure 5As shown, the input pipe 1 is symmetrically provided with a fixed frame 8 on both sides, and a cleaning liquid input pipe 91 is installed on the fixed frame 8. The end of the cleaning liquid input pipe 91 is rotatably connected with a spray head 9. The spray head 9 is provided with a plurality of spray holes. The spray head 9 is used to flush the filter screen 5. A cleaning rod 10 is installed on the side of the spray head 9 provided with the spray holes. The cleaning rod 10 is arranged between the spray holes of the spray head 9. The cleaning rod 10 is made of soft material and has a bending function. The setting provides convenience for the turnover of the filter screen 5. The end of the cleaning rod 10 is provided with a spherical sponge. The cleaning rod 10 is in contact with the filter screen 5.

[0026] As shown in Figure 4 and Figure 5 A motor 11 is installed on the fixed frame 8. A gear set 12 is arranged between the spray head 9 and the output shaft of the motor 11. The gear set 12 includes a driving gear installed on the output shaft of the motor 11 and a driven gear installed on the spray head 9. The driving gear is engaged with the driven gear and performs a deceleration motion. The rotary power of the motor 11 is transmitted to the spray head 9 through the gear set 12 to drive the spray head 9 to rotate. The rotation of the spray head 9 drives the cleaning rod 10 to move, thereby comprehensively and multi-angelly cleaning the filter screen 5.

[0027] As shown in Figure 6 A fan blade 13 is rotatably arranged on the filter screen 5 and used to disperse the color paint. When the liquid flows through the fan blade 13, the fan blade 13 rotates to disperse the liquid, so that the liquid is more uniformly distributed on the entire filter screen 5, thereby further improving the filtering efficiency and quality.

[0028] The liquid (such as color paint) enters the communication joint 101 from the input pipe 1. At least one filter screen 5 in the communication joint 101 intercepts and removes larger particles and impurities in the liquid. When it is necessary to replace or clean the filter screen 5 in the filter frame 4, the filter frame 4 is moved to one side of the communication joint 101. The filter frame 4 moves along the rodless slide rail 2 through the sliding blocks 3 on both sides of the filter frame 4 until the sliding blocks 3 on the filter frame 4 move to the end of the rodless slide rail 2, thereby realizing seamless replacement of the filter screen 5. During the movement of the filter frame 4, when the pinion 6 is engaged with the rack 7, the rack 7 drives the pinion 6 to rotate with the further movement of the filter frame 4. The rotation of the pinion 6 drives the filter screen 5 to rotate, so that the filter screen 5 is turned over by 180 degrees. In this way, the accumulated impurities on the filter screen 5 are removed, preventing the filter screen 5 from being clogged and improving the filtering efficiency. At the same time, the cleaning liquid is sprayed on the filter screen 5 through the spray head 9. The power of the motor 11 is transmitted to the spray head 9 through the gear set 12 when the motor 11 is working, thereby driving the spray head 9 to rotate. Through the first motion of the cleaning rod 10 and the filter screen 5, the filter screen 5 is efficiently and comprehensively cleaned.

[0029] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
