Description

Technical Field

[0001] The utility model relates to the field of sand washing machines, in particular to a wheel-type sand washing machine. Background Art

[0002] The washing wheel of the wheel sand washing machine is driven by a motor and a reducer, and rotates continuously in the water tank, performing periodic motion, so that the sand and gravel materials in the water tank are stirred and rolled in the water, and then dehydrated through the dewatering screen and discharged from the equipment.

[0003] The filter screen is subject to greater wear and tear from the material during the rotation of the grinding wheel, and the strength of the filter screen is lower than that of other parts of the grinding wheel due to the holes in the filter screen. Therefore, the filter screen is the most easily damaged part of the grinding wheel. In traditional wheel-type sand washing machines, the filter screen on the grinding wheel is generally fixed on the grinding wheel, which makes it difficult to replace the filter screen when it is damaged. The damaged filter screen has a greater impact on the filtering effect of the material. Utility Model Content

[0004] The purpose of the utility model is to provide a wheel-type sand washing machine for overcoming the above-mentioned defects in the prior art.

[0006] Through the above technical solution, the grinding wheel rotates, scooping the material in the water tank into the cavity composed of two circular baffles and several partitions. After being filtered by the filter screen, the sewage after sand washing flows back into the water tank, and the cleaned material remains in the cavity and is poured onto the conveying device through the rotation of the grinding wheel. The detachable filter screen is convenient for replacement after wear.

[0007] One side of the partition close to the connecting plate extends along the outer circumference of the connecting plate to form an arc-shaped fixing portion, and the fixing portion is fixed to the connecting plate by rivets.

[0008] Through the above technical solution, the arc-shaped fixing portion is conducive to its fitting on the connecting plate, thereby increasing the contact area between the two and further improving the fixing strength.

[0009] Both sides of the fixing portion perpendicular to the annular baffle extend in a direction away from the connecting plate to form a protruding portion, and the outer periphery of the filter screen abuts against the protruding portions of two adjacent fixing portions respectively.

[0010] Through the above technical solution, the protruding portion of the fixing part is conducive to limiting and fixing the filter.

[0011] The two sides of the connecting plate perpendicular to the annular baffle are gradually inclined from outside to inside in a direction away from the filter screens on both sides. The edge of the filter screen close to the connecting plate is parallel to the side of the adjacent connecting plate and the two are in contact with each other.

[0012] Through the above technical solution, the inclined two sides of the connecting plate and the inclined two side edges of the filter screen facilitate the installation of the filter screen from the inner side of the grinding wheel to between two adjacent connecting plates, further facilitating the disassembly and assembly of the filter screen.

[0013] Two limit seats distributed along the axis direction of the connecting plate are fixed on the inner side surface of the connecting plate, and two pressure blocks sliding circumferentially along the inner side surface of the connecting plate are slidably connected in the limit seat. The pressure blocks can extend out of the limit seat and cooperate with the fixing part to clamp the filter screen. The two pressure blocks are symmetrically arranged, and a "V"-shaped elastic sheet is fixed between the two pressure blocks. A through groove is provided on the side of the limit seat close to the axis of the annular baffle, and a pressure plate passing through the through groove is fixed on the side of the pressure block close to the axis of the annular baffle.

[0014] Through the above technical solution, the pressing block and the fixing part clamp the filter screen, so that the filter screen remains stable during the operation of the sand washing machine.

[0015] The side surface of the pressing block away from the elastic sheet is configured as an inclined surface which gradually inclines from the fixing portion toward the limiting seat toward the elastic sheet.

[0016] Through the above technical solution, the inclined surface of the pressing block is set to facilitate the installation of the filter.

[0017] The beneficial effects of the utility model are as follows: the grinding wheel rotates, scooping the material in the water tank into the cavity composed of two annular baffles and a plurality of partitions, and the sewage after sand washing is filtered by the filter screen, so that the washed material flows back into the water tank, and the cleaned material remains in the cavity and is poured onto the conveying device through the rotation of the grinding wheel. The detachable filter screen is convenient for replacement after wear, and the pressing block and the fixing part clamp the filter screen, so that the filter screen remains stable during the operation of the sand washing machine.

A conveying device is provided on one side of the water tank 10. The grinding wheels pour the cleaned materials onto the conveying device after rotation. A rotating shaft 20 is provided at the axis of the grinding wheels. The grinding wheels are fixed to the rotating shaft 20 through a connecting rod. The rotating shaft 20 is connected to the motor through a reducer. The motor drives the reducer to rotate, thereby driving the grinding wheels to rotate. The grinding wheels include two annular baffles 30. The two annular baffles A plurality of connecting plates 33 are fixed between the two annular baffles 30, and the plurality of connecting plates 33 are circumferentially distributed with the axis of the annular baffle 30 as the center. A filter screen 31 is detachably connected between two adjacent connecting plates 33. The plurality of connecting plates 33 and the plurality of filter screens 31 form a complete cylindrical shape. A partition plate 32 is fixed on the outer periphery of the connecting plate 33. The partition plate 32 is arranged obliquely to the outer peripheral surface of the connecting plate 33. The partition plate 32 is located between the two annular baffles 30, and the partition plate 32 is fixed on the two annular baffles 30 near both sides of the annular baffles 30.

[0029] Reference Figure 3 One side of the partition plate 32 close to the connecting plate 33 extends along the outer circumference of the connecting plate 33 to form an arc-shaped fixing portion 321, and the fixing portion 321 is fixed to the connecting plate 33 by rivets.

[0030] Reference Figure 2 、 Figure 3 Both sides of the fixing portion 321 perpendicular to the annular baffle 30 extend away from the connecting plate 33 to form a protruding portion, and the outer periphery of the filter screen 31 abuts against the protruding portions of the two adjacent fixing portions 321.

[0031] Reference Figure 2 、 Figure 3 The two sides of the connecting plate 33 perpendicular to the annular baffle 30 are gradually inclined from the outside to the inside in the direction away from the filter screens 31 on both sides. The edge of the filter screen 31 close to the connecting plate 33 is parallel to the side of the adjacent connecting plate 33 and the two are in contact with each other.

[0032] Reference Figure 4 、 Figure 5 Two limit seats 40 distributed along the axis direction of the connecting plate 33 are fixed on the inner side of the connecting plate 33. Two pressure blocks 43 sliding circumferentially along the inner side of the connecting plate 33 are slidably connected in the limit seat 40. The pressure blocks 43 can extend out of the limit seat 40 and cooperate with the fixing portion 321 to clamp the filter screen 31. The two pressure blocks 43 are symmetrically arranged. A "V"-shaped elastic sheet 42 is fixed between the two pressure blocks 43. The elastic sheet 42 is formed by bending a stainless steel sheet.
