Technical Field

[0001] The utility model relates to the technical field of cleaning, in particular to a filter screen debris cleaning device. Background Art

[0002] In the production process of silica sand, filters are mainly used to filter out debris and screen silica sand particles to remove impurities and particles that do not meet the particle size requirements; for example, the filter in the silica sand raw material cleaning process is used to filter out impurities such as clay and mud, and the filter in the silica sand primary screening process and the filter in the magnetic mineral removal process are used to screen out coarse particles of waste sand.

[0003] After the filter has been used for a long time, some debris and particles will be embedded in the mesh of the filter, gradually reducing the filter's debris removal and filtering function. The current common method is to first remove the filter and then rinse it with water or blow it with gas, which is a relatively cumbersome operation. In the prior art, in order to reduce the number of disassembly and maintenance, a movable and rotatable brush roller is installed in the corresponding equipment to clean the debris embedded in the filter mesh. However, this simple brushing cleaning method does not have an ideal cleaning effect, and there are still stubborn debris residues.

[0004] Therefore, in order to solve the above problems, a filter screen debris cleaning device is proposed. Utility Model Content

[0009] Furthermore, the width of each comb tooth gradually decreases from the side away from the brush roller to the side close to the brush roller.

[0010] Specifically, the positioning assembly includes a push-pull electromagnet and a wedge block. Guide grooves are provided on both sides of the rectangular frame. Wedge blocks are slidably installed in the guide grooves. Push-pull electromagnets are fixedly installed on the side walls of the rectangular frame through support frames. The output ends of the push-pull electromagnets are fixedly assembled with the wedge blocks respectively.

[0011] Furthermore, when the wedge block abuts against the lower side of the swing arm, the brush roller is separated from the vibration plate.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model provides an embodiment: a filter debris cleaning device, including an electric screw module 4 and a linear guide 12, a rectangular frame 1 is fixedly installed between the slide of the electric screw module 4 and the slide of the linear guide 12; the electric screw module 4 and the linear guide 12 are existing equipment, and the rectangular frame 1 is used for reciprocating translation between them.

[0024] One end of a swing arm 5 is rotatably mounted on both sides of the rectangular frame 1 through a torsion shaft 3, and a brush roller 7 for cleaning the filter is rotatably mounted between the other ends of the swing arms 5. A reduction motor 13 is fixedly mounted on the side wall of one of the swing arms 5, and the output end of the reduction motor 13 is connected to the brush roller 7; the torsion shaft 3 is an existing component composed of a shaft pin and a torsion spring, which is used to generate a downward swinging force on the swing arm 5 and the brush roller 7, and the reduction motor 13 can rotate the brush roller 7 when working.

[0025] A stripping comb 6 for cleaning the brush roller 7 is fixedly installed between the swing arms 5 to prevent debris from adhering to the brush roller 7 and reducing the cleaning effect; the rectangular frame 1 is installed with a positioning component 2 for limiting the swing arm 5, and the positioning component 2 can limit the swing amplitude of the swing arm 5, so that the brush roller 7 is pressed against the filter screen, or the brush roller 7 is separated from the filter screen; a vibration plate 9 for vibrating the filter screen is installed on the lower side of the inner part of the rectangular frame 1 through a vibration absorber 10, and a vibrator 11 is fixedly installed on the lower side of the vibration plate 9; the vibration absorber 10 and the vibrator 11 are existing components, and the vibrator 11 will make the vibration plate 9 vibrate when working, thereby vibrating the lower side of the filter screen, which is conducive to the upward separation of debris, and the vibration absorber 10 can prevent the vibration on the vibration plate 9 from being transmitted to the rectangular frame 1, thereby preventing the entire device from vibrating.

[0026] For details, please refer to Figure 4 The stripping comb 6 includes an arc plate 61 and comb teeth 62. The thickness of the arc plate 61 gradually decreases from the side away from the brush roller 7 to the side close to the brush roller 7. The arc plate 61 is evenly provided with slots on the side close to the brush roller 7, and comb teeth 62 are formed between adjacent slots. The integrally formed stripping comb 6 has better overall strength. The comb teeth 62 are used to strip off the debris adhered to the brush roller 7, and the debris is discharged along the arc plate 61 to the side away from the brush roller 7.

[0027] Furthermore, the comb teeth 62 are bent downward at one end near the brush roller 7, which is more conducive to the discharge and guidance of debris, and the comb teeth 62 extend into the bristles of the brush roller 7 by at least 3 cm, which can peel off the debris embedded in the bristles of the brush roller 7, and the debris is cleaned more thoroughly.

[0028] Furthermore, the width of each comb tooth 62 gradually decreases from the side away from the brush roller 7 to the side close to the brush roller 7 , making it easier for the comb teeth 62 to extend into the bristles of the brush roller 7 .

[0029] For details, please refer to Figure 2 The positioning assembly 2 includes a push-pull electromagnet 21 and a wedge block 22. Guide grooves are provided on both sides of the rectangular frame 1, and wedge blocks 22 are slidably installed in the guide grooves. The side walls of the rectangular frame 1 are fixedly installed with the push-pull electromagnet 21 through a support frame, and the output ends of the push-pull electromagnet 21 are fixedly assembled with the wedge blocks 22 respectively; the push-pull electromagnet 21 is an existing component, and the wedge block 22 is retracted along the guide groove when the push-pull electromagnet 21 is energized, and the wedge block 22 is extended along the guide groove when the push-pull electromagnet 21 is de-energized, and the wedge block 22 is a wedge-shaped structure with a chamfered upper side, which is conducive to abutting with the swing arm 5.

[0030] Specifically, the top block 8 is evenly and fixedly mounted on the upper surface of the vibration plate 9. The top block 8 can contact the bottom of the filter screen when the vibration plate 9 vibrates, which is more conducive to the upward discharge of debris.

[0031] Alternatively, see Figure 5 A conveying channel 15 is provided inside the vibration plate 9, and the conveying channel 15 is S-shaped. Water outlets 14 connected to the conveying channel 15 are evenly provided on the top of the vibration plate 9, and the water outlets 14 are staggered with the top block 8; the conveying channel 15 is connected to an external water supply system (mainly including a pump and a water tank), and high-pressure water is sprayed upward through the conveying channel 15 and the water outlet 14, providing additional impact force, which acts on the filter net together with the vibration, and can further enhance the effect of discharging debris upward.

[0032] Now Figure 2 The working principle of this embodiment is described based on the azimuth relationship:

[0033] The electric screw module 4, the linear guide rail 12, the reduction motor 13, the vibrator 11 and the push-pull electromagnet 21 and other electrical components are electrically connected to the controller in the external control cabinet and are uniformly controlled through the control panel on the control cabinet.

[0034] The filter is a mesh box-shaped structure with folded edges on all sides. During installation, the electric lead screw module 4 and the linear guide rail 12 are fixedly installed in the corresponding equipment through a support seat. The filter is located between the brush roller 7 and the vibration plate 9, and the two ends of the filter are detachably connected to the equipment.

[0035] When removing impurities or filtering, the electric lead screw module 4 and the linear guide 12 keep the rectangular frame 1 and other components at the right end of the filter without affecting normal work; after the filter is gradually blocked, the electric lead screw module 4 and the linear guide 12 drive the rectangular frame 1 to reciprocate 2 to 3 times. During the impurity removal process, the positioning component 2 is in a retracted state. At this time, the swing arm 5 is only subjected to the force of the torsion shaft 3 and swings downward, so that the brush roller 7 is against the filter and rotates clockwise to brush the impurities in the filter mesh to the left, and the stripping comb 6 continues to clean the impurities adhered to the brush roller 7 and guides it to the left. At the same time, the vibrator 11 causes the vibration plate 9 to vibrate, thereby vibrating the filter from the bottom, which is conducive to the impurities to be separated upward and brushed away until the impurities reach the waste discharge port at the left end for discharge; it can also be combined with the recoil high-pressure water sprayed upward at the water outlet 14 to perform comprehensive impurity cleaning in a variety of ways, and the cleaning effect is better.

[0036] After the impurities are removed, the rectangular frame 1 is reset to the right end, the positioning assembly 2 is extended, and when the wedge block 22 abuts against the lower side of the swing arm 5, the brush roller 7 is separated from the vibration plate 9 to prevent the brush roller 7 from being deformed due to long-term pressure, thereby affecting its reuse.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
