Description

Technical Field

[0001] This utility model relates to the technical field of sand washing equipment, and in particular to a silica sand scrubbing machine. Background Technology

[0002] Silica sand scrubbing is a process that removes impurities from the surface of silica sand through mechanical force and the abrasive force between sand grains. Specifically, scrubbing involves using mechanical equipment to scrub the silica sand to remove thin films of iron, bonded and muddy mineral impurities from its surface, and further break down non-monolithic mineral aggregates. Subsequently, a grading process is used to purify the silica sand.

[0003] In existing silica sand washing processes, the slurry enters the scrubbing machine chamber through the feed pipe. The impeller generates intense turbulence under strong agitation, causing significant friction and collisions between the mineral particles. The thin film of impurities coating the surface of the particles, being of low strength, is easily peeled off through friction and impact. Furthermore, the material rolls within the washing tank driven by the impeller, carrying away lighter impurities and foreign objects. This achieves the purpose of cleaning the silica sand.

[0004] However, the silica sand scrubbing process uses a large amount of water for rinsing, which not only leads to serious energy consumption but also generates significant noise from the equipment, affecting the hearing health of operators. The large amount of rinsing water carries solid waste, resulting in a heavy workload for subsequent solid waste treatment. Furthermore, the inability to differentiate and agitate silica sand added sequentially during overall mixing leads to significant differences in cleaning effectiveness, making it impossible to guarantee the overall cleaning result. Utility Model Content

[0008] The mounting cavity is equipped with a spray assembly, and the spray section of the spray assembly is located inside the cleaning cavity;

[0009] The cleaning chamber is equipped with a stirring assembly and a material shaking assembly in sequence.

The stirring assembly centrifugally disperses the silica sand particles during the stirring process, while spraying occurs during this process. The tilted tank with its horizontal axis enhances the stirring efficiency through the combined effect of gravity and stirring. Furthermore, a shaking component is installed after the stirring assembly to further clean the silica sand raw material curled within the stirring assembly. The shaking component disperses and cleans the raw material, which is then screened and collected by the filtration unit. This effectively ensures the stratified collection of the silica sand, guaranteeing a consistent cleaning effect. Attached Figure Description

[0048] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] This embodiment relates to a silica sand scrubbing machine, which, in general, is as follows: Figures 1 to 5 As shown, the silica sand scrubbing machine includes an inclined tank 1 with a cavity. An annular pipe 2 is also provided inside the tank 1, dividing the cavity into a cleaning chamber 3 located in the middle, and an installation chamber 4 located between the annular pipe 2 and the tank 1. The installation chamber 4 is equipped with a spray assembly 5, the spraying part of which is located within the cleaning chamber 3. A stirring assembly 6 and a shaking assembly 7 are sequentially arranged inside the cleaning chamber 3. A filter unit 8 is provided at the outlet of the shaking assembly 7. One end of the tank 1 has a feed inlet 9, and the other end has a discharge channel 10, which communicates with the filter unit 8.

[0050] The silica sand washing machine of this embodiment uses a spray assembly 5 installed in the installation cavity 4. The spray section of the spray assembly 5 is located inside the cleaning cavity 3. During the movement of the stirring assembly 6 and the shaking assembly 7, the silica sand raw material is cleaned by spraying. Then, the silica sand of different particle sizes is screened by the filter unit 8, the rinsing water is filtered, and finally the cleaned silica sand particles are collected. The silica sand particles are centrifugally dispersed by the stirring assembly 6 during the stirring process, and spraying is carried out during this process. The tank 1, which is set with a horizontal axis when tilted, is used for stirring. The stirring efficiency is increased by the combined action of gravity and stirring. Furthermore, by setting the shaking assembly 7 after the stirring assembly 6, the silica sand raw material curled in the middle of the stirring assembly 6 is further sprayed and cleaned. The shaking assembly 7 disperses and cleans the raw material, and finally, it is screened and collected by the filter unit 8. This effectively ensures the layered collection of silica sand and guarantees the uniformity of the silica sand cleaning effect.

[0051] As a preferred embodiment, such as Figures 1 to 5 As shown, the stirring assembly 6 includes a first drive unit 601 connected to the outside of the tank body 1, a stirring shaft 602 connected to the power output end of the first drive unit 601, and several support plates 603 disposed on the stirring shaft 602. The support plates 603 have an annular surrounding plate 604 on their outer sides, and the surrounding plate 604 has several through grooves arranged axially. Several spraying components 5 are evenly distributed along the radial circumference of the tank body 1. In this embodiment, the first drive unit 601 adopts...

The feeding plate 701 has a feeding chamber that communicates with the inner cavity of the surrounding plate 604. A shaking assembly 7 is located within the feeding chamber. In this embodiment, the feeding plate 701 is annular in shape, with a diameter larger than that of the surrounding plate 604, and its inner hole is equal to that of the surrounding plate 604. Preferably, the end face of the surrounding plate 604 abuts against the feeding plate 701, and the surrounding plate 604 rotates with the stirring shaft 602. The first drive unit 601 is a servo motor.

[0053] Preferably, the material shaking assembly 7 includes a second drive unit 702 connected to the outside of the tank body 1, a push rod 703 connected to the power output end of the second drive unit 702, a connecting frame 704 hinged to one end of the push rod 703, and a material shaking plate 705 connected to one end of the connecting frame 704. A support plate 706 is provided on the annular pipe 2 for mounting the connecting frame 704, and the connecting frame 704 is pivotally connected to the support plate 706. With the above configuration, the second drive unit 702 uses a telescopic hydraulic cylinder. The second drive unit 702 pushes the push rod 703 to reciprocate radially along the tank body 1, thereby causing the lower end of the connecting frame 704 to swing, thus realizing the swing of the material shaking plate 705. This receives the silica sand material output from the agitation process, shakes the silica sand material during the swinging process, and performs spray washing during this process to improve the spray washing effect.

[0054] Furthermore, such as Figure 1 As shown, the connecting frame 704 includes a telescopic rod 7041, a support rod 7042 hinged to the telescopic rod 7041, and a mounting rod 7043 connected to the support rod 7042. A plurality of shaking plates 705 are spaced apart along the height direction of the mounting rod 7043. When the second drive unit 702 drives the push rod 703 to reciprocate radially along the tank body 1, the shaking plates 705 swing relative to the tank body 1. The swing amplitude of the shaking plates 705 can be adjusted by adjusting the telescopic rod 7041.

[0055] In addition, the filtration unit 8 includes an inclined plate 801 connected between the feeding plate 701 and the tank 1. The inclined plate 801 encloses a storage space, within which several screening plates 802 are provided. The screening holes of the screening plates 802 are arranged in a progressively smaller manner from top to bottom. It should be noted that automatic valves are provided between the enclosure plate 604 and the feeding plate 701, and between the feeding plate 701 and the inclined plate 801, abutting against the inner wall of the annular pipe 2. These automatic valves are used to connect or close the fluid movement between two adjacent materials, so as to achieve filtration after the spraying is completed by stirring and shaking.

[0056] Preferably, such as Figures 1 to 5As shown, the spray assembly 5 includes a mounting base 501 extending along the length of the tank body 1, a plurality of retaining seats 502 spaced apart along the length of the mounting base 501, a nozzle assembly 503 pivotally connected to the retaining seats 502, and a drive assembly 504 that drives the nozzle assembly 503 to swing.

[0057] like Figures 1 to 5 As shown, the drive assembly 504 includes a third drive unit 5041, an active swing arm 5042 connected to the power output end of the third drive unit 5041, a connecting rod 5043 hinged to the swing arm, and a long rod 5044 connecting several nozzle assemblies 503. The third drive unit 5041 drives the active swing arm 5042 to rotate, so that the long rod 5044 swings back and forth along the length of the mounting base 501.

[0058] Furthermore, the nozzle assembly 503 includes a bend 5031 connected to the retainer 502, a connecting plate 5032 connected to the bend 5031, and a high-pressure nozzle 5033 located at one end of the bend 5031. The other end of the bend 5031 is used to connect a water pipe, which is connected to an external water supply device.
