[0002] Quartz sand is a kind of quartz particle processed from quartzite. Quartzite is a kind of non-metallic mineral, which is a kind of hard, wear-resistant and chemically stable silicate mineral. The color of quartz sand is milky white or colorless and translucent. Quartz sand is an important industrial mineral raw material, which is a non-chemical hazardous product and is widely used in glass, casting, ceramics, fireproof materials, ferrosilicon smelting, metallurgical flux, metallurgy, building, chemical industry, plastics, rubber, abrasive, filter material and other industries.

[0003] Before feeding, the quartz sand needs to be screened by manual operation to remove unqualified and large particles. In the prior art, the quartz sand is transported to a designated place by a truck, then screened by a screening machine, and then fed to the corresponding equipment for use by a feeding system. On the one hand, the increase of labor cost is caused by the need for loading shovel turning and the complicated operation process. On the other hand, the loading shovel turning process is easy to introduce external impurities, causing pollution of the quartz sand raw material. CONTENT OF THE INVENTION

[0004] In view of the above problems, the present application provides a high-efficiency feeding system applied to quartz sand, which can effectively reduce the additional process of quartz sand in the feeding process and avoid pollution of quartz sand due to loading shovel turning.

[0005] According to an aspect of the present application, a high-efficiency feeding system applied to quartz sand is provided. The high-efficiency feeding system applied to quartz sand comprises a feeding table, a buffer tank is arranged on the feeding table, a shunt device is arranged at the bottom of the buffer tank, a first transfer belt is arranged below the shunt device, a second transfer belt is arranged at the output end of the first transfer belt, the shunt device comprises a V-shaped groove connected to the bottom of the buffer tank, two shunt pipes are communicated with the V-shaped groove through a three-way valve at the bottom end of the V-shaped groove, a screening component is arranged at the end of the shunt pipe, the screening component comprises a screening box, a vibration motor is connected to the screening box, a screen cylinder is arranged in the screening box, the top of the screen cylinder penetrates upward to the screening box, the bottom end of the shunt pipe extends to the inside of the screen cylinder through a hose, a dedusting pipe is communicated with the bottom of the screen cylinder through a dedusting valve, the other end of the dedusting pipe extends downward to the outside of the screening box, the inner bottom wall of the screening box is inclined, a discharge pipe is communicated with the lowest part of the inner bottom of the screening box, and the discharge pipe extends downward above the first transfer belt.

[0006] In some embodiments, two ear plates are fixed to the top of the screen cylinder, and the ear plates are hinged to the top wall of the screening box via a pivot.

[0007] In some embodiments, the bottom of the screen cylinder tapers inward and tilts downward to form a conical screen disk, and the impurity removal pipe is connected to the bottom of the conical screen disk.

[0008] In some embodiments, a ramp is provided on one side of the unloading platform for vehicles to drive into.

[0009] In some embodiments, the pouring platform is welded from a steel frame, and the buffer box is welded to the pouring platform via steel rods.

[0010] In some embodiments, a gravity sensing device is provided on one side of the buffer box on the pouring platform, and a winding device is provided on the other side of the buffer box on the pouring platform.

The following embodiments are only used to more clearly illustrate the technical scheme of the application, and therefore only serve as examples, and cannot be used to limit the protection scope of the application. Unless otherwise defined, all the technical and scientific terms used in the present application have the same meanings as those commonly understood by the person skilled in the art to which the present application belongs; the terms used in the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the application; the terms “include” and “have” and any variations thereof in the specification and claims of the present application and the above description of the drawings are intended to cover the non-exclusive inclusion.

[0020] Specifically, refer to Figures 1 to 3 , Figure 1 The overall cross-section structure schematic diagram of the high-efficiency feeding system for quartz sand provided by the embodiment of the application is shown in the figure, Figure 2 The high-efficiency feeding system for quartz sand 100, Figure 1 The enlarged view at A, Figure 3 The high-efficiency feeding system for quartz sand 100, Figure 2The enlarged view at B. The high-efficiency feeding system 100 applied to quartz sand includes a tipping platform 110 for vehicles to drive in, which are loaded with quartz sand raw materials, which can be poured into the buffer tank 120. The tipping platform 110 is provided with a buffer tank 120, the structure and size of which can be set according to actual needs to meet the use requirements. The buffer tank 120 is used to accommodate the quartz sand in the vehicle and gradually discharge the quartz sand to the transfer belt below through the flow dividing device 130. The bottom of the buffer tank 120 is provided with a flow dividing device 130 for alternately conveying the quartz sand in the buffer tank 120 to two screening components 160. A primary transfer belt 140 is arranged below the flow dividing device 130, and the output end of the primary transfer belt is provided with a secondary transfer belt 150. The primary transfer belt 140 and the secondary transfer belt 150 are both prior art, which can be a belt conveyor with a turning function and a material leakage prevention function. The flow dividing device 130 includes a V-shaped groove 131 connected to the bottom of the buffer tank 120, which can ensure that the quartz sand in the buffer tank 120 falls completely into the flow dividing pipe 133. The bottom end of the V-shaped groove 131 is communicated with two flow dividing pipes 133 through a three-way valve 132, and the end of the flow dividing pipe 133 is provided with a screening component 160. During operation, the three-way valve 132 is controlled to make the quartz sand raw materials in the V-shaped groove 131 alternately enter the two flow dividing pipes 133, and further flow into the two screening components 160 through the flow dividing pipes 133. The screening component 160 is used to remove unqualified large particles from the quartz sand raw materials. The screening component 160 includes a screening box 161, which can be welded from a steel plate. The screening box 161 can be erected above the primary transfer belt 140 by supporting rod members. A vibration motor 162 is connected to the screening box 161, which is used to drive the whole screening box 161 to vibrate, thereby completing the screening operation. A screen cylinder 163 is arranged in the screening box 161, and mesh holes are formed in the screen cylinder 163. The diameter of the mesh holes can be set according to the actual particle diameter to be screened. The top of the screen cylinder 163 penetrates upwardly to the screening box 161, the bottom end of the flow dividing pipe 133 extends to the inside of the screen cylinder 163 through a hose 134, and the quartz sand raw materials in the flow dividing pipe 133 enter the screen cylinder 163 through the hose 134. Since the flow dividing pipe 133 and the screen cylinder 163 are connected through the hose 134, the vibration motor 162 does not affect the flow dividing pipe and other components during the vibration of the whole screening box 161.The bottom of the screen cylinder 163 is communicated with a foreign matter removal pipe 165 through a foreign matter removal valve 164. After the whole screening box 161 is shaken by the vibration motor 162, the larger particles of the raw materials in the screen cylinder 163 are left in the screen cylinder 163, and the remaining raw materials pass through the screen cylinder 163 into the inside of the screening box 161, and finally flow out through the discharging pipe 166 to the upper side of the first transfer belt 140 for transfer. The other end of the foreign matter removal pipe 165 extends downward to the outside of the screening box 161. When the foreign matter removal valve 164 is opened, the remaining foreign matters in the screen cylinder 163 can be guided out of the screening box 161 through the foreign matter removal pipe 165. Generally, the foreign matters guided through the foreign matter removal pipe 165 are accumulated on both sides of the first transfer belt 140, which can be transferred to the outside of the factory by a forklift in the future. The inner bottom wall of the screening box 161 is inclined, and the discharging pipe 166 is communicated with the lowest part of the inner bottom of the screening box 161 and extends downward to the upper side of the first transfer belt 140.

[0021] As can be seen from the above, in the embodiment of the present application, by arranging the buffer box 120 and the shunt device 130 and the screening component 160 at the bottom of the buffer box 120, the operator only needs to pour the quartz sand raw materials in the vehicle into the buffer box 120 along the pouring table 110 during the operation process. The quartz sand raw materials in the buffer box 120 will be alternately transferred into the two screening components 160 for screening in the future. The screened quartz sand raw materials will fall onto the first transfer belt 140 for transfer, and the large-particle waste will be drained out through the foreign matter removal pipe 165, thereby greatly reducing the labor cost, avoiding the introduction of external impurities by loading the forklift during the production process, and further improving the working efficiency of the present application because the screening component 160 is two and the two screening components 160 are alternately used.

[0022] In some embodiments, the top of the screen cylinder 163 is fixed with two ear plates 163a which are hinged to the top wall of the screening box 161 through a rotating shaft. In the embodiment of the present application, by the above arrangement, compared with the fixed form of the screen cylinder 163 and the screening box 161 during the operation of the vibration motor, a certain gap can be arranged at the connection between the ear plate 163a and the rotating shaft, so that the top of the screen cylinder 163 is in a relatively relaxed state, and the vibration frequency of the screen cylinder 163 is further enhanced.

[0023] In some embodiments, the bottom of the screen cylinder 163 is inwardly contracted and downwardly inclined to form a conical sieve disc, and the foreign matter removal pipe 165 is communicated with the lower side of the conical sieve disc. In the embodiment of the present application, by the above arrangement, the screening area of the bottom of the screen cylinder 163 is increased, and the screening speed is further improved.

[0024] In some embodiments, the slope 111 is arranged on one side of the material pouring table 110 for the vehicle to drive in. In the embodiments of the present application, the slope 111 is arranged to facilitate the vehicle carrying the quartz sand to drive in.

[0025] In some embodiments, the material pouring table 110 is welded by steel frame, and the buffer box 120 is welded on the material pouring table 110 by steel rods. In the embodiments of the present application, the above arrangement can effectively guarantee the stability of the material pouring table 110 and stably fix the buffer box 120.

[0026] In some embodiments, the gravity sensing device 112 is arranged on one side of the buffer box 120 on the material pouring table 110, and the winding device is arranged on the other side of the buffer box on the material pouring table 110. The winding device includes the rotating motor 113, the rotating motor 113 is coaxially connected with the wire 114 disc, the wire 114 disc is connected with the wire 114, the top of the buffer box 120 is hinged with the turnover cover 115, and the wire 114 is connected to the top of the turnover cover 115. In the embodiments of the present application, when the vehicle carrying the quartz sand drives to the material pouring table 110, the vehicle will press the gravity sensing device 112, and the rotating motor 113 will be turned on and pull the turnover cover 115 to open through the wire 114. The opening angle of this time is not more than ninety degrees. Then, when the vehicle finishes discharging and drives away from the material pouring table 110, the gravity sensor is no longer pressed. At this time, the rotating motor 113 is reversed to reset the turnover cover 115 and re-enter the top of the buffer box 120 to realize sealing, so as to avoid the external pollutants entering the inside of the buffer box 120.
