Description

Technical Field

[0001] The utility model relates to the technical field of wood chip cleaning equipment, in particular to a wood chip washing machine which can prevent materials from getting stuck. Background Art

[0002] In the fiberboard manufacturing process, a washing machine is needed to wash the wood chips to remove sand and gravel from the wood chips. During washing, the wood chips are sent into the washing machine and float on the water surface. The washing drum continuously beats and presses the wood chips on the water surface, so that the wood chips on the water surface are repeatedly pressed into the water, so that the sand and gravel attached to the wood chips are removed, and the purpose of cleaning the wood chips is achieved.

[0003] The Chinese utility model patent, authorization announcement number CN 210132596 U, discloses a wood chip washing machine with anti-jamming, including a machine case and a washing drum arranged in the machine case, and a plurality of anti-jamming convex ribs are respectively arranged on the left and right end surfaces of the horizontal drum body. Due to the addition of the anti-jamming convex ribs, when the horizontal drum body rotates, the anti-jamming convex ribs can form a disturbance effect on the gap between the left and right end surfaces of the washing drum and the left and right inner wall surfaces corresponding to the machine case, which reduces the possibility of wood chips staying in this gap, thereby solving the problem of easy jamming in the existing washing machine. Although the utility model has a simple structure, it can effectively solve the problem of easy jamming between the left and right end surfaces of the washing drum and the inner wall surface of the machine case.

[0004] The above device solves the technical problems raised in the background technology, but in practical applications, the above solution still has certain defects, such as:

[0005] The above scheme is respectively provided with a plurality of anti-stuck convex ribs on the left and right end surfaces of the horizontal cylinder. The horizontal cylinder rotates to drive the stuck convex ribs to form turbulence in the gap, thereby reducing the retention of wood chips in the gap. However, since the stuck convex ribs are small, the turbulence generated is small, and the water flow disturbance force may not be able to resist the buoyancy of the wood chips floating on the bottom, so the problem of stuck materials in the gap will still occur. Utility Model Content

[0006] The utility model aims to provide a wood chip washing machine which can prevent the wood chips from getting stuck, so as to solve the problems mentioned in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wood chip washing machine for preventing material jamming, comprising a washing box, a bottom bucket, a water outlet pipe, a valve and a flip cover, wherein two connecting rods are movably connected to the inner side of the washing box, a rotating roller is fixed between the two connecting rods, a plurality of pressing plates for pressing wood chips are fixed on the roller body of the rotating roller, one of the connecting rods is connected to a driving member, and the driving member drives the rotating roller to rotate;

[0008] A gap is formed between the rotating roller and the side wall of the washing box. Multiple through holes are opened on both sides of the rotating roller. The water inlet holes of the through holes are located on the surface of the rotating roller, and a water collecting shell is fixed on the outside of the water inlet holes.

[0009] Preferably, the water outlet hole of the through hole is arranged obliquely upward in the gap.

[0010] Preferably, trumpet-shaped reducing tubes are fixed to both ends of the rotating roller.

[0011] Preferably, a filter box is fixed to the end of the water inlet side of the water collecting shell.

[0012] Preferably, a plurality of support rods are arranged on the side of the filter box from top to bottom;

[0013] The length of the support rod increases gradually from top to bottom.

[0014] Preferably, a spherical ball is fixed to the end surface of the support rod.

[0015] Preferably, a hollow inclined plate that bends inwards is fixed to the top of the pressing plate.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The anti-jamming wood chip washing machine is provided with a pressing plate, a through hole and a water collecting shell. The driving member drives the rotating roller and the pressing plate to rotate counterclockwise. When the water collecting shell rotates with the rotating roller, external water will enter the water collecting shell and finally be discharged through the water outlet of the through hole. At this time, the water pressure in the gap is greater than the external water pressure, so that the water in the gap is discharged to the outside, which can effectively increase the water disturbance force and prevent the floating wood chips from entering the gap and causing jamming.

[0023] 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.

[0024] The device is used for cleaning wood chips to solve the problem of material jamming in existing wood chip washing machines. Example 1

[0025] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a wood chip washing machine for preventing material from getting stuck, comprising a washing box 1, a bottom bucket 3, a water outlet pipe 4, a valve and a flap 2, wherein the valve is connected to the pipe body of the water outlet pipe 4, and the flap 2 is a double-opening cover. When in use, the flap 2 is opened, and then the wood chips are put into the washing box 1, and two connecting rods are movably connected to the inner side of the washing box 1, and a rotating roller 5 is fixed between the two connecting rods, and a plurality of pressing plates 6 for pressing the wood chips are fixed on the roller body of the rotating roller 5, wherein one of the connecting rods is connected to a driving member, and the driving member is preferably a reduction motor, which drives the rotating roller 5 to rotate through the reduction motor, so that the pressing plate 6 continuously beats and presses the wood chip raw materials floating on the water surface into the water, thereby separating sand and gravel and other debris from the wood chip raw materials.

[0026] A gap is formed between the rotating roller 5 and the side wall of the washing box 1. A plurality of through holes 7 distributed in a ring shape are provided on both sides of the rotating roller 5. The distances between the through holes 7 are equal. It should be noted that the water inlet of the through hole 7 is located on the surface of the rotating roller 5. A slope is formed on the outer surface of the water inlet to increase the width of the water inlet and facilitate water inlet. A water collecting shell 8 is fixed on the outer side of the water inlet.

[0027] like Figure 2 As shown, the water outlet of the through hole 7 is arranged obliquely upward in the gap.

[0028] Specifically, when in use, the controller controls the driving member to start, such as Figure 3 As shown, the driving member drives the rotating roller 5 and the pressing plate 6 to rotate counterclockwise, and the pressing plate 6 continuously beats and presses the wood chip raw materials floating on the water surface into the water. When the water collecting shell 8 rotates with the rotating roller 5, the external water will enter the water collecting shell 8 and finally be discharged through the water outlet of the through hole 7. At this time, the water pressure in the gap is greater than the external water pressure, so that the water in the gap is discharged to the outside, which can effectively increase the water disturbance force and prevent the floating wood chips from entering the gap and causing material jamming. Example 2

[0029] On the basis of the first embodiment, trumpet-shaped reducers 9 are fixed at both ends of the rotating roller 5. The arrangement of the reducers 9 can not only reduce the spacing at the gap, but also increase the water pressure of the water discharged from the gap to the outside, further improving the anti-jamming effect. Example 3

[0030] Based on the first or second embodiment, a filter box 10 is fixed to the end of the water inlet side of the water collecting shell 8. The filter box 10 can prevent impurities in the water from entering the through hole 7, thereby avoiding blockage of the through hole 7.

[0031] In addition, if Figure 3 As shown, a plurality of support rods 11 are arranged on the side of the filter box 10 from top to bottom, and the length of the support rods 11 gradually increases from top to bottom. The support rods 11 are used to block the wood chips. Such an arrangement is to prevent the wood chips from being adsorbed on the surface of the filter box 10 and affecting the water outlet effect of the through hole 7.

[0032] The length of the support rod 11 gradually increases from top to bottom, so that the end surface of the support rod 11 forms a slope, and when the water collecting shell 8 rotates counterclockwise, the wood chips can be separated from the support rod 11. Example 4

[0033] On the basis of the third embodiment, a ball 12 is fixed on the end surface of the support rod 11 . The provision of the ball 12 reduces the friction between the support rod 11 and the wood chip, making it easier for the wood chip to detach from the support rod 11 . Example 5

[0034] Based on any one of the embodiments 1 to 4, Figure 4 As shown, an inwardly curved hollow inclined plate 601 is fixed at the top of the pressing plate 6. The hollow inclined plate 601 can bring the floating wood chips to the bottom of the water, thereby increasing the contact area and contact time between the wood chips and water, which is more conducive to cleaning the wood chips.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
