[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2This utility model provides a technical solution: a straw washing device for papermaking, including a box 1 with an open top structure, a gantry frame 2 fixedly installed on the top of the box 1, a sliding frame 3 that can move laterally inside the box 1, a mesh frame 4 detachably embedded in the sliding frame 3 through a positioning component, a pair of supports 5 fixedly installed on the upper wall of the mesh frame 4, a main shaft 6 rotatably installed between the pair of supports 5, a pair of gears 7 fixedly installed through the pair of supports 5 at both ends of the main shaft 6, a pair of racks 8 fixedly installed on both sides of the upper wall of the box 1 to mesh with the gears 7, a plurality of turning rods 9 axially provided on the side wall of the main shaft 6, a reciprocating push rod 10 fixedly installed on one side of the box 1, a support ear 11 fixedly installed on the upper wall of one side of the sliding frame 3, the telescopic end of the reciprocating push rod 10 being fixedly connected to the support ear 11, and a spraying component provided on the gantry frame 2.

[0020] By adopting the above technical solution, after the straw is put into the mesh frame 4, the reciprocating push rod 10 drives the sliding frame 3 to move laterally back and forth along the box body 1; the gear 7 rolls along the rack 8 as the sliding frame 3 moves, driving the main shaft 6 and the turning rod 9 to rotate and turn the straw. The spraying component sprays water to wash the straw, and impurities fall into the bottom of the box body 1 from the gaps in the mesh frame 4 with the water flow and are discharged through the drain pipe 19. The above components form a collaborative cleaning structure of reciprocating motion, rotating turning and spraying, which solves the problems of incomplete cleaning and low efficiency of traditional equipment.

[0021] In this embodiment, the positioning component includes a pair of positioning blocks 12 fixedly disposed on both sides of the mesh frame 4. The inner walls of both sides of the sliding frame 3 are provided with a pair of slots for the positioning blocks 12 to slide into. A pair of screws 13 are rotatably installed on the outer walls of both sides of the sliding frame 3. An adjusting plate 14 is screwed onto the screws 13. A pair of positioning pins 15 are provided on the side wall of the adjusting plate 14. The side wall of the sliding frame 3 is provided with through holes for the positioning pins 15 to pass through. The side wall of the positioning block 12 is provided with pin holes for the positioning pins 15 to be inserted.

[0022] By adopting the above technical solution, when installing the mesh frame 4, the mesh frame 4 is embedded in the sliding frame 3, and the positioning block 12 is embedded in the groove to achieve initial positioning. The screw 13 is rotated to push the adjusting plate 14, so that the positioning pin 15 passes through the through hole and is inserted into the pin hole of the positioning block 12 to complete the fixation. When disassembling, the screw 13 is rotated in the opposite direction, the positioning pin 15 is disengaged from the pin hole, and the mesh frame 4 can be pulled out.

[0023] In this embodiment, the spraying assembly includes a plurality of spray pipes 16 fixedly disposed on the top of the portal frame 2. The plurality of spray pipes 16 are parallel to each other and spaced apart within the portal frame 2. The lower wall of the spray pipes 16 is provided with a plurality of nozzles 17 along the axial direction.

[0024] By adopting the above technical solution, the spray pipe 16 is supplied with water by an external water pump, the nozzles 17 are distributed along the movement path of the straw, and the sprayed fan-shaped water flow covers the entire area of ​​the net frame 4. The movement of the sliding frame 3 and the turning rod 9 turn the straw so that it is fully exposed in the water flow, and the mud, sand and impurities are washed away.

[0025] In this embodiment, the inner walls on both sides of the housing 1 are provided with a pair of guide rails 18, and the two sides of the sliding frame 3 are slidably connected to the pair of guide rails 18 through guide grooves.

[0026] By adopting the above technical solution, the slide frame 3 slides along the guide rail 18 under the drive of the reciprocating push rod 10. The cooperation between the guide groove and the guide rail 18 restricts the up and down movement of the slide frame 3 and ensures the stability of horizontal sliding.

[0027] In this embodiment, the screw 13 is further configured such that a handle is installed at one end.

[0028] By adopting the above technical solution, the extension and retraction of the positioning pin 15 can be adjusted without tools by turning the screw 13 with a handle.

[0029] In this embodiment, the bottom side of the box 1 is provided with a drain pipe 19.

[0030] By adopting the above technical solution, during the cleaning process, wastewater containing impurities falls from the gaps in the mesh frame 4 into the bottom of the box 1 and is continuously discharged through the drain pipe 19.

[0031] In this embodiment, the lower wall of the box 1 is provided with a traveling wheel 20.

[0032] By adopting the above technical solution, according to the needs of the production process, the box 1 is pushed to make the walking wheels 20 roll, and the equipment is moved to the vicinity of the straw raw material stacking area for cleaning, or transferred to the pulping equipment for direct unloading.

[0033] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0034] Example: During operation, align the positioning block 12 with the groove of the sliding frame 3, push the mesh frame 4 into it until it fits completely, rotate the screw 13 to push the adjusting plate 14, so that the positioning pin 15 passes through the through hole and inserts into the pin hole of the positioning block 12 to complete the fixing. Put the straw to be cleaned into the mesh frame 4, and the reciprocating push rod 10 drives the sliding frame 3 to move laterally back and forth along the box 1. The gear 7 rolls along the rack 8 as the sliding frame 3 moves, driving the main shaft 6 and the turning rod 9 to rotate and turn the straw. The spray pipe 16 supplies water through an external water pump, and the sprayed water fully washes the straw below. The sewage falls into the bottom of the box 1 through the mesh frame 4 and is discharged from the drain pipe 19. After cleaning, turn off the spray assembly and the reciprocating push rod 10, turn the handle in the opposite direction to make the positioning pin 15 disengage from the pin hole, pull out the mesh frame 4, pour out the cleaned straw to the conveying equipment or temporary storage area, rinse the mesh frame 4 and reinstall it to prepare for the next batch of cleaning. It is convenient to use.
