[0062] A quartz sand cleaning device with internal cleaning function solves the technical problem of quartz sand needing to be cleaned and screened in the related art, and achieves the positive effect of being able to clean and screen quartz sand. The overall idea is as follows:

[0063] Implementation method 1: Figure 1 , Figure 2 As shown; a quartz sand cleaning device with internal cleaning function, comprising:

[0064] Basic frame 10;

[0065] A first cavity 20 connected to the base frame 10, wherein the first cavity 20 has a first inner space 21;

[0066] The second cavity 30 is connected to the base frame 10 and is arranged opposite to the first cavity 20. The second cavity 30 has a second inner space 31. The second inner space 31 is symmetrically spaced with the first inner space 21. After the second cavity 30 is combined with the first cavity 20, a third inner space 32 is formed at the top. The third inner space 32 is connected with the first inner space 21 and the second inner space 31.

[0067] A feed liquid spraying member 40 is connected to the top of the first cavity 20 and the second cavity 30, connected to the base frame 10, and partially disposed in the third inner space 32, and is used to introduce quartz sand raw materials into the first inner space 21 and the second inner space 31, and clean the quartz sand raw materials;

[0068] A middle section liquid spraying member 50 is connected to the middle position of the first cavity 20 and the second cavity 30 and is connected to the base frame 10 for cleaning the quartz sand raw material;

[0069] and a screening element 60, connected to the bottom of the first cavity 20 and the second cavity 30, and connected to the base frame 10, for screening the quartz sand raw material, screening the dirt and debris in the quartz sand raw material, and the cleaned and screened quartz sand slides onto the conveyor 100;

[0070] Specifically, during implementation, a basic frame 10, a first cavity 20, a second cavity 30, a feed liquid spraying component 40, a middle liquid spraying component 50 and a screening component 60 are provided;

[0071] The basic frame 10 forms a reliable supporting structure, which is conducive to the connection and arrangement of other components. The quartz sand raw material enters from the feed spray part 40, and while being cleaned by the feed spray part 40, it enters the first inner space 21 and the second inner space 31, and is further cleaned by the middle spray part 50, and then is screened along the screening part 60. The screening part 60 screens the dirt and debris in the quartz sand raw material, and the cleaned and screened quartz sand slides onto the conveyor 100, thereby realizing the cleaning and screening of the quartz sand.

[0072] Implementation method 2: Figure 1 , Figure 2 As shown; during implementation, the basic frame 10 is welded from square tubes and plates to form a cubic frame structure, forming a reliable supporting structure, which is conducive to connecting and arranging other components.

[0073] Implementation method 3: Figure 1 , Figure 2 , Figure 3 , Figure 4As shown; during implementation, the first cavity 20 and the second cavity 30 have the same structure, both comprising: a shell 20-1, which is a "["-shaped structure; two first side connecting plates 20-2, symmetrically connected to the shell 20-1; a support seat 20-3, connected to the shell 20-1, used to connect to the basic frame 10; a bending plate 20-4, connected to the shell 20-1, forming the first inner space 21 or the second inner space 31 between the shell 20-1; and a supporting guard plate 20-5, connected to the shell 20-1, disposed in the first inner space 21 or the second inner space 31, used to first contact the quartz sand raw material dropped from the feed liquid spraying member 40;

[0074] The housing 20-1 is formed by bending a plate;

[0075] The first side connecting plate 20-2 is a rectangular plate structure, which is welded to the housing 20-1, which is convenient for inserting bolts to connect the first cavity 20 and the second cavity 30, and the assembly is relatively convenient;

[0076] The support seat 20-3 has a "["-shaped structure, is welded to the housing 20-1, and is used to be connected to the base frame 10 by inserting bolts, so the assembly is relatively convenient;

[0077] The bending plate 20-4 is welded to the housing 20-1, so the assembly is relatively convenient;

[0078] The bending angle A of the bending plate 20-4 is 135°, which is conducive to the quartz sand raw material entering the feeding liquid spraying part 40 to slide down the bending plate 20-4, and in the process of sliding, it is washed by the cleaning liquid, thereby achieving the purpose of cleaning;

[0079] The bending plate 20-4 has a plurality of first grooves 20-41, and the first grooves 20-41 are arranged at intervals; the first grooves 20-41 are arranged to increase the contact area with the quartz sand raw material, to accommodate the quartz sand raw material, to slow down the sliding speed of the quartz sand raw material, so that the quartz sand raw material and the cleaning liquid can be fully in contact, and at the same time, since the cleaning liquid flows continuously, and the weight of the dirt and debris is less than the weight of the quartz sand, as the cleaning liquid flows, the dirt, debris and quartz sand will gradually separate, and part of the dirt (such as dust, etc.) will also be integrated into the cleaning liquid, thereby achieving the purpose of cleaning;

[0080] The supporting guard plate 20-5 is formed by bending a plate, and is connected to the housing 20-1 by bolts. The width of the supporting guard plate 20-5 is smaller than the length of the first groove 20-41. The control of the size enables the supporting guard plate 20-5 to not only protect the spray pipe 51, but also not affect the quartz sand raw material entering the bending plate 20-4.

[0081] The supporting guard plate 20-5 has a plurality of protrusions 20-51, and the protrusions 20-51 are arranged at intervals; the cross section of the protrusion 20-51 is an isosceles triangle structure, and when the quartz sand raw material falls, it touches the protrusion 20-51, causing a collision, which is conducive to the dirt and debris on the quartz sand falling off;

At the same time, since the cleaning liquid flows continuously, the quartz sand raw material is cleaned without clogging. The mixture of the quartz sand raw material and the cleaning liquid falls along the inverted conical trough 40-1 onto the supporting guard plate 20-5.

[0085] The top cover 40-2 comprises: a top plate 40-2-1, connected to the top of the housing 20-1, having the first liquid through port 40-22 and the second liquid through port 40-23; and an annular side edge 40-2-2, connected to the top plate 40-2-1, having the fourth inner space 40-21 between the top plate 40-2-1; the top plate 40-2-1 is a square plate structure, and after a sealing gasket is placed between the top plate 40-2-1 and the housing 20-1, bolts are inserted to connect, and the assembly is relatively convenient; the annular side edge 40-2-2 is welded to the top plate 40-2-1;

[0106] The first guide channel 64 includes: an inclined channel 64-1, one end of which is connected to the base frame 10; and a third side connecting plate 64-2, which is connected to the other end of the inclined channel 64-1 and connected to the bent screen plate 61-1;

[0108] The angle B between the inclined material channel 64-1 and the horizontal plane is 45°, which is conducive to the sliding down of dirt and debris (dirt is dust, sand, etc., and debris is small particles of quartz sand, crushed stone slag, etc.);

[0109] The second guide channel 65 includes: a square flange 65-1 connected to the bottom of the first screening shell 61 and the second screening shell 62; a side wall plate 65-2, one end of which is connected to the square flange 65-1; and an inclined plate 65-3 connected to the other end of the side wall plate 65-2, and a fifth inner space 65-4 is formed between the inclined plate 65-3, the side wall plate 65-2 and the square flange 65-1, and the fifth inner space 65-4 is connected to the screening space 63;

[0110] After sealing gaskets are placed between the square flange 65-1 and the first screening shell 61 and the second screening shell 62, bolts are inserted to connect them, and the assembly is relatively convenient;

[0111] The side wall plate 65-2 is welded together from three plates and is welded to the square flange 65-1;

[0112] The inclined plate 65-3 is welded to the side wall plate 65-2;

[0113] The second guide channel 65 is provided to facilitate the quartz sand after screening to slide along the inclined plate 65-3 to the conveyor 100 (the conveyor 100 is a common structure in the prior art, such as a screw conveyor), thereby reducing the probability of the quartz sand falling on the ground.

[0114] Implementation 7: Figure 1 , Figure 2 , Fig.10 , Fig.11 As shown; it also includes: two push cleaning members 70, one connected to the first cavity 20, and the other connected to the second cavity 30, for cleaning the screening member 60;

[0115] The push cleaning member 70 includes: a cylinder body 71, connected to the boss 20-11 on the side wall of the housing 20-1, and the telescopic shaft on the cylinder body 71 passes through the boss 20-11; a connecting arm 72, connected to the telescopic shaft, and arranged in the first inner space 21 or the second inner space 31; two bearing seats 73, symmetrically connected to the connecting arm 72; and a rolling brush 74, connected between the bearing seats 73, for contacting the bent screen plate 61-1 and rolling the bent screen plate 61-1;

[0116] The cylinder body 71 is an air cylinder or an oil cylinder, which is used to generate a linear driving force, and the linkage roller brush 74 moves back and forth along the bending screen plate 61-1, thereby cleaning the bending screen plate 61-1 and preventing the bending screen plate 61-1 from being blocked;

[0117] The connecting arm 72 is roughly in the shape of a "[" structure, and has two symmetrically arranged "U"-shaped grooves 72-1; the "U"-shaped grooves 72-1 are provided to facilitate the insertion of the roller brush 74 and the connection between the roller brush 74 and the bearing seat 73;

[0118] The bearing seat 73 is a common structure in the prior art, such as a flange bearing seat, which is connected to the connecting arm 72 by bolts, is easy to install and disassemble, and can reliably connect the roller brush 74.

[0119] The roller brush 74 includes: a shaft roller, the end of which is connected to the bearing seat 73; and an outer layer, which is wrapped around the outer circle at the middle position of the shaft roller and is used to scrape the bent screen plate 61-1; the outer layer is a commonly used structure in the prior art, such as: felt, which is conducive to scraping the bent screen plate 61-1, cleaning the bent screen plate 61-1, and preventing the bent screen plate 61-1 from being blocked.

[0120] Implementation 8: Figure 2 As shown; it also includes: two guide plates 80, symmetrically arranged, the guide plates 80 are connected to the inner wall of the housing 20-1, and are used to guide the quartz sand raw material to the bending plate 20-4;

[0121] When the quartz sand raw material falls along the inverted conical trough 40-1, although it can contact with the cleaning liquid, since the quartz sand is in granular form, it will be bounced after falling onto the supporting guard plate 20-5, which affects the sliding position of the quartz sand raw material along the bending plate 20-4. A guide plate 80 is provided to form a barrier, which can guide the quartz sand when it bounces, thereby improving the effect of the quartz sand raw material sliding along the bending plate 20-4, so that the quartz sand raw material is fully in contact with the cleaning liquid, thereby improving the cleaning effect;

[0122] The working principle is as follows: the quartz sand raw material enters from the feed pipe 40-5 at the feed spray part 40, and while being cleaned by the feed spray part 40, the quartz sand raw material enters the first inner space 21 and the second inner space 31 along the inverted cone trough 40-1, and is further cleaned by the middle spray part 50 at the bending plate 20-4, and then slides onto the bending screen plate 61-1, and is screened along the bending screen plate 61-1 to screen out dirt and debris in the quartz sand raw material, and the cleaned and screened quartz sand slides onto the conveyor 100;

[0123] Here is an explanation, the above description uses "quartz sand raw material" and "quartz sand", because the cleaning process is a dynamic process, and the "quartz sand raw material" needs to go through this "cleaning process" to be cleaned, so that dirt and debris are separated from the "quartz sand", therefore, only after being screened by the bent screen plate 61-1, the "quartz sand" that enters the screening space 63 is cleaned and relatively clean, and the previous ones can be understood as "quartz sand raw material". After seeing the disclosed content, ordinary technicians in this field can know directly and without doubt, without the need for creative labor or excessive experiments;

[0124] In the description, it should be understood that the terms "upper", "lower", "left", "right", "front", "back" and the like indicating directions or positional relationships are based on the positional relationships described in the drawings and are only for the convenience of description or simplified description, rather than indicating specific directions that must be possessed; the operation process described in the embodiments is not an absolute usage procedure and may be adjusted accordingly in actual use;

[0125] Unless otherwise defined, the technical or scientific terms used herein shall have the usual meanings understood by persons with ordinary skills in the relevant field; the words "first", "second" and similar words used in the specification and claims do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "a" do not necessarily indicate a quantity limitation, but indicate the existence of at least one, which needs to be determined according to the content of the embodiment;

[0126] The above is only a preferred specific implementation method, but the scope of protection is not limited to it. Any equivalent replacement or change made according to the technical solution and its inventive concept within the technical scope disclosed by any technician familiar with this technical field should be covered by the scope of protection.
