Description

Technical Field

[0001] This utility model relates to the field of washing and screening machine technology, specifically a cylindrical washing and screening machine. Background Technology

[0002] The washing and separating machine can clean and separate mud and impurities from sand and gravel. Its novel sealing structure, adjustable overflow weir plate, and reliable transmission device ensure effective washing and dewatering. It is widely applicable to washing, grading, and impurity removal in industries such as highways, hydropower, and construction, as well as washing fine and coarse-grained materials. It is particularly suitable for sand and gravel used in construction and road building.

[0003] The existing Chinese utility model patent with publication number CN208066529U discloses a cylindrical washing and screening machine, including a washing and screening drum. A gear cover is fitted onto the surface of the washing and screening drum. A front support roller is movably connected to the left side of the bottom of the washing and screening drum, and a rear support roller is movably connected to the right side of the bottom of the washing and screening drum. A transmission support is rotatably connected to the bottom of the washing and screening drum, corresponding to the position of the gear cover. A transmission motor is installed on the right side of the transmission support. A control box is fixedly installed on the right side of the transmission motor. A discharge funnel is connected to the right side of the washing and screening drum. This cylindrical washing and screening machine, through the cooperation of a conveyor motor, a conveyor frame, a driving wheel, a driven wheel, a conveyor belt, a transmission wheel, a transmission belt, a first weighing device, and a second weighing device, solves the problem that after ore washing and screening, workers still need to transport and process the discharged ore again. Due to the large weight of the ore, this not only increases the labor intensity of workers but also reduces the processing efficiency of the ore.

[0004] Existing cylindrical washing machines require the cylinder to rotate, and the cylinder is positioned above the two side support rollers. During equipment transfer, the cylinder may move due to vibrations during transportation, causing misalignment between the cylinder and the support rollers. In addition, the screen holes on the surface of the cylinder of the existing cylindrical washing machine are located on the discharge side of the cylinder. During use, the water used for rinsing can only flow out through the screen holes of the cylinder, causing some wastewater to flow out from the coarse material discharge position, affecting the subsequent transfer of coarse material.

[0026] Please see Figure 1 - Figure 4In this embodiment, a cylindrical washing and screening machine includes: a support frame 1, a chip removal pipe 11 fixedly installed on the top of the support frame 1, limit rods 12 fixedly installed on the left and right sides of the support frame 1, a base 13 fixedly installed at the top of the limit rods 12 and on the top of the support frame 1, a connecting bearing 14 fitted inside the base 13, a limit shaft 15 inserted inside the connecting bearing 14, a rubber roller 16 inserted at the center of the limit shaft 15, a fixing ring 17 fixedly installed at the top of the base 13, a drive motor 18 fixedly installed on the top of the support frame 1, a reducer 19 fixedly installed at the end of the shaft of the drive motor 18, a receiving groove 110 fixedly installed inside the support frame 1, a metal mesh 111 fitted on the bottom surface of the receiving groove 110, a drainage groove 112 fixedly installed below the receiving groove 110, a water inlet pipe 113 inserted at the front end of the support frame 1, and a water outlet pipe 114 inserted below the water inlet pipe 113.

[0027] The top of the support frame 1 is inclined at an angle of five degrees. There are three chip removal pipes 11, which are installed equidistantly on the top of the support frame 1. The chip removal pipes 11 are inclined at an angle of five degrees. A trapezoidal opening is provided at the bottom of the chip removal pipes 11. The fixing ring 17 is fixedly connected to the base 13 by bolts. The fixing ring 17 and the inner wall of the base 13 form a cylindrical tubular structure. The limiting shaft 15 is rotatably connected to the fixing ring 17 and the base 13 by connecting bearings 14 at both ends. The rubber roller 16 is installed at the left and right ends of the front and rear sides of the support frame 1 via the limiting shaft 15, as well as the limiting rod 1. At the top of 2, the shaft of the drive motor 18 is fixedly connected to the power input end of the reducer 19. The output end of the reducer 19 is fixedly connected to the rear end of the limit shaft 15 at the left rear of the top of the support frame 1. The bottom end of the receiving groove 110 is a sloping structure. The top end of the receiving groove 110 is fixedly connected to the support frame 1. The bottom end of the drainage groove 112 is fixedly connected to the support frame 1. The front end of the water inlet pipe 113 is provided with a flange structure. The water outlet pipe 114 is installed equidistantly at the rear of the water inlet pipe 113. The water outlet pipe 114 is located above the rear chip discharge pipe 11 and the central chip discharge pipe 11. The water outlet pipe 114 is inclined towards the inner wall of the roller 2.

[0028] Specifically, the drive motor 18 is model YBZR200L-8-15KW, the reducer 19 is model QS20, the support frame 1 allows the drum 2 to be in an inclined state, and the chip discharge pipe 11 restricts the position of the material falling. After the water flow washes the material, the water flow will carry the fine material through the grid structure of the drum 2 and guide it to the top of the receiving groove 110 by the chip discharge pipe 11. The position of the connecting bearing 14 is restricted by the base 13 and the fixing ring 17, so that the position of the limiting shaft 15 is restricted while allowing the limiting shaft 15 to rotate. The limiting rod 12 can restrict the position of the base 13, so that the upper left and upper right of the two connecting rings 21 in the middle of the drum 2 are restricted by the rubber roller 16. The rubber roller 16 between the bases 13 above the support frame 1 can restrict the connecting rings 2 1. It plays a supporting role. The drive motor 18 can drive the reducer 19. The reducer 19 can drive the left rear limit shaft 15 of the support frame 1 to rotate, thereby causing the rubber roller 16 to drive the connecting ring 21 to rotate. After the material enters the receiving groove 110, it will slide to the left end of the receiving groove 110 under the action of gravity. Water and debris with a particle size smaller than the aperture of the metal mesh 111 will fall into the drainage groove 112 and be discharged from the right side. The water inlet pipe 113 is located above the center of the roller 2. In use, the water inlet pipe 113 is connected to the water pump through the flange structure at the front end of the water inlet pipe 113, thereby delivering water for rinsing the material to the water outlet pipe 114. Due to the installation position of the water outlet pipe 114, the rinsing process is located above the rear chip discharge pipe 11 and the central chip discharge pipe 11.

[0029] A roller 2 is inserted inside the chip removal pipe 11. A connecting ring 21 is fixedly installed on the outside of the roller 2. An end plate 22 is fixedly installed at the rear end of the roller 2. A fixed bearing 23 is fitted into the center of the end plate 22. An inlet pipe 24 is fitted into the inside of the fixed bearing 23. A limit frame 25 is fixedly installed on the outside of the inlet pipe 24.

[0030] The roller 2 and the chip removal pipe 11 are rotatably connected. The surface of the roller 2 is provided with three annular grids at equal intervals, and the grid positions correspond one-to-one with the positions of the chip removal pipe 11. The surface of the connecting ring 21 is provided with an annular recess structure that fits into the rubber roller 16. The connecting ring 21 is installed at equal intervals on the surface of the roller 2, and the installation position of the connecting ring 21 corresponds one-to-one with the rubber roller 16. The top end of the feed pipe 24 is a flared structure, and the bottom end of the feed pipe 24 is rotatably connected to the end plate 22 through the fixed bearing 23. The bottom end of the limiting frame 25 is fixedly connected to the support frame 1.

[0031] Specifically, the roller 2 can screen materials. At the same time, the roller 2 is in an inclined state. When the roller 2 rotates, the internal materials will move towards the front end of the roller 2. The connecting ring 21 can restrict the position of the roller 2 while driving the roller 2 to rotate. The end plate 22 can prevent materials from slipping from the rear end of the roller 2. The feed pipe 24 is connected to the end plate 22 through the fixed bearing 23 to prevent the end plate 22 from affecting the feed pipe 24 when it rotates. The flared structure at the top of the feed pipe 24 can facilitate the addition of materials into the inside of the roller 2. The limiting frame 25 can restrict the position of the feed pipe 24.

[0032] In use, there are three chip removal pipes 11, which are installed equidistantly above the support frame 1. Water outlet pipes 114 are installed equidistantly behind the water inlet pipe 113, and are located above the rear and central chip removal pipes 11. The water outlet pipe 114 is inclined towards the inner wall of the drum 2. During use, the water inlet pipe 113 is connected to a water pump via a pipe through the flange structure at its front end, thus supplying water for rinsing the material to the water outlet pipe 114. Due to the installation position of the water outlet pipe 114, the rinsing process occurs above the rear and central chip removal pipes 11. After the water flow rinses the material, it carries fine materials through the grid structure of the drum 2 and guides them from the chip removal pipes 11 to the receiving groove 110. Water that cannot be discharged from the surface of coarse materials can pass through the frontmost chip removal pipe 114. The wastewater is discharged at 1 o'clock to avoid a large amount of wastewater being discharged from the front end of the drum 2. The top of the limiting rod 12 is fixedly installed with a base 13. The base 13 and the inner wall of the fixing ring 17 can be closed to form a cylindrical tubular structure, thereby limiting the position of the connecting bearing 14. It can limit the position of the limiting shaft 15 while allowing the limiting shaft 15 to rotate. The limiting rod 12 can limit the position of the base 13, so that the upper left and upper right of the two connecting rings 21 in the middle of the drum 2 are limited by the rubber rollers 16. The rubber rollers 16 between the bases 13 above the support frame 1 can support the connecting rings 21. The drum 2 is limited to the center of the chip discharge pipe 11 by the rubber rollers 16 at both ends of the front and rear sides of the support frame 1 and the rubber roller 16 at the top of the limiting rod 12 and the corresponding connecting rings 21 on the surface of the drum 2. This prevents the drum 2 from moving during transportation.

[0033] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
