Description

Technical Field

[0001] The present application relates to the technical field of quartz sand production and processing, and in particular to a quartz sand impurity removal device. Background Art

[0002] Quartz sand is quartz particles formed by crushing quartz stone. Quartz stone is a non-metallic mineral, a silicate mineral, with hardness, wear resistance, and stable chemical properties. Its main mineral component is SiO2. Quartz sand is an important industrial mineral raw material, not a chemical hazardous substance. It is widely used in many industrial fields such as glass, casting, ceramics, fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials, etc.

[0003] In the production and processing of quartz sand, impurity removal is a key link. At present, the most common way to remove impurities is to use a filter to perform filtering and impurity removal operations. The filter is usually customized according to the specifications of the quartz sand particle size, and its pore size needs to be accurately matched to ensure effective interception of impurity particles. However, during the long-term filtering operation, due to the soil and mineral particles that may be mixed in the quartz sand raw materials and some tiny dust generated during the processing, it is very easy to adhere to the filter mesh and gradually accumulate, causing the mesh to be blocked, which will have an adverse effect on the filtration efficiency. The blocked filter needs to be manually cleaned regularly. The cleaning process is cumbersome and time-consuming, which not only increases the labor intensity of the workers, but also affects the overall impurity removal efficiency. Summary of the invention

DETAILED DESCRIPTION

[0021] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0022] The quartz sand impurity removal equipment of the embodiment of the present application is described below in conjunction with the accompanying drawings.

[0023] like Figure 1-Figure 3 As shown, the quartz sand impurity removal equipment of the embodiment of the present application may include a support frame 10, a frame 20, a sealing assembly 30, a filter screen 40, a cleaning mechanism 50, two transmission mechanisms 60 and a driving assembly 70.

[0024] The frame 20 is arranged on the support frame 10 , and two partitions 21 arranged side by side are arranged in the frame 20 . The two partitions 21 separate the frame 20 into a first chamber 22 , a second chamber 23 and a third chamber 24 , and a U-shaped frame 25 is arranged on the frame 20 .

[0025] The sealing assembly 30 is disposed on the top of the first chamber 22 , and the filter screen 40 is fixedly disposed on the top of the second chamber 23 .

[0026] The cleaning mechanism 50 is movably disposed in the U-shaped frame 25 , and the cleaning mechanism 50 is in contact with the top surface of the filter screen 40 .

[0027] A transmission shaft 26 rotatably connected thereto is disposed in the third chamber 24 , and both ends of the transmission shaft 26 pass through the third chamber 24 . Two transmission mechanisms 60 are disposed at both ends of the transmission shaft 26 , respectively.

[0028] The driving assembly 70 is disposed on one side of the support frame 10 , and the driving assembly 70 is connected to one of the transmission mechanisms 60 .

[0029] Specifically, when it is necessary to remove impurities from the quartz sand, the relevant staff can pour the quartz sand to be removed into the cleaning mechanism 50. Since the quartz sand poured into the cleaning mechanism 50 is in a piled state, a portion of the quartz sand that falls on the filter screen 40 passes through the mesh of the filter screen 40 and is discharged into the second chamber 23.

[0030] At this time, the staff can control the driving assembly 70 to drive the transmission mechanism 60 to drive the cleaning mechanism 50 to move back and forth. The reciprocating cleaning mechanism 50 reciprocates the quartz sand that falls on the filter net 40, which can not only improve the filtration efficiency, but also automatically clean the filter net in real time without excessive manual operation, effectively reducing the burden on workers and reducing maintenance costs.

[0031] When it is necessary to clean the impurities (e.g., mineral particles) filtered on the filter screen, the staff can control the sealing assembly 30 to open the top opening of the first chamber 22. As the cleaning mechanism 50 reciprocates on the filter screen 40, the cleaning mechanism 50 moves the impurities filtered on the filter screen 40 to the top of the first chamber 22 and discharges them through the first chamber 22.

[0032] In order to clearly explain the above embodiment, in one embodiment of the present application, as Figure 1 and Figure 3 As shown, the sealing assembly 30 may include a sealing plate 31 and two retractable mechanisms 32 .

[0033] The sealing plate 31 is disposed on the top of the first chamber 22 , and one end of the sealing plate 31 is pivotally connected to the frame 20 via a rotating shaft, wherein the top surface of the sealing plate 31 is flush with the top surface of the filter screen 40 .

[0034] The two retractable mechanisms 32 are arranged side by side below the sealing plate 31 , and one end of the retractable mechanism 32 is pivotally connected to the other end of the sealing plate 31 , and the other end of the retractable mechanism 32 is pivotally connected to the side wall of the first chamber 22 .

[0035] It should be noted that the retractable mechanism 32 described in this embodiment may be a cylinder, a hydraulic cylinder or an electric retractable rod, and the initial state of the output end of the retractable mechanism 32 is an extended state.

[0036] It is understandable that when it is necessary to clean the impurities filtered on the filter screen 40, the staff can control the output end of the retractable mechanism 32 to retract, and pull the sealing plate 31 to flip downward, thereby opening the top opening of the first chamber 22 to facilitate the discharge of the filtered impurities from the first chamber 22.

[0037] Further, in one embodiment of the present application, Figure 1 and Figure 3As shown, the cleaning mechanism 50 may include a cleaning frame 51 and two sets of sliders 52 , wherein the cleaning frame 51 is movably disposed on the top wall of the filter screen 40 .

[0038] Slideways 251 are respectively provided on the two side walls of the U-shaped frame 25, and two groups of sliders 52 are respectively slidably arranged in the corresponding slideways 251, and the two groups of sliders 52 are respectively fixedly connected to the two side walls of the cleaning frame 51, wherein each group of sliders 52 may include two sliders 52 arranged side by side.

[0039] Further, in one embodiment of the present application, Figure 1 and Figure 2 As shown, the transmission mechanism 60 may include a pulley 61 and a connecting rod 62 , wherein the pulley 61 is sleeved and fixed on the transmission shaft 26 .

[0040] One end of the connecting rod 62 is away from the transmission shaft 26 and is pivotally connected to the side wall of the pulley 61 , and the other end of the connecting rod 62 is pivotally connected to the side wall of the cleaning frame 51 .

[0041] Further, in one embodiment of the present application, Figure 1 As shown, the driving assembly 70 may include a driving mechanism 71 , a driving pulley 72 and a first belt 73 , wherein the driving mechanism 71 is disposed on one side of the support frame 10 , and an output end of the driving mechanism 71 is connected to the driving pulley 72 .

[0042] The first belt 73 is sleeved on the driving pulley 72 and the pulley 61 in one of the transmission mechanisms 60 .

[0043] It should be noted that the driving mechanism 71 described in this embodiment may be a driving motor.

[0044] Specifically, after the quartz sand to be removed is poured into the cleaning frame 51, the staff can control the driving mechanism 71 to drive the active pulley 72 to rotate, and the rotating active pulley 72 drives the pulley 61 to rotate through the first belt 73. The rotating pulley 61 drives the cleaning frame 51 to reciprocate on the filter screen 40 through the connecting rod 62. The reciprocating cleaning frame 51 makes the quartz sand swing back and forth on the filter screen 40, thereby accelerating the filtering efficiency of the quartz screen. The cleaning frame 51 can also scrape and clean the impurities blocked on the filter screen 40 during the movement, thereby effectively ensuring the filtering performance of the filter screen 40.

[0045] The filtered quartz sand is discharged into the second chamber 23 through the mesh of the filter screen 40 , and the impurities filtered on the filter screen 40 are located in the cleaning frame 51 .

[0046] When it is necessary to clean the impurities in the cleaning frame 51, the staff can control the output end of the retractable mechanism 32 to retract, and pull the sealing plate 31 to flip downward, thereby opening the top opening of the first chamber 22. When the cleaning frame 51 moves to above the first chamber 22, the filtered impurities fall into the first chamber 22 under the action of their own gravity and are discharged through the bottom outlet of the first chamber 22.

[0047] As a possible situation, in order to improve the cleaning effect of impurities (such as dirt and dust, etc.) attached to the mesh of the filter 40, the staff can also set a brush (not shown in the figure) on the bottom wall of the cleaning frame 51.

[0048] Further, in one embodiment of the present application, Figure 1 As shown, the above-mentioned quartz sand impurity removal equipment may further include a feeding mechanism 80 , and the feeding mechanism 80 includes a hopper 81 and a bellows 82 , wherein the hopper 81 is mounted on the U-shaped frame 25 .

[0049] One end of the bellows 82 is connected to the outlet of the hopper 81 , and the other end of the bellows 82 is connected to the upper port of the cleaning frame 51 .

[0050] It is understandable that the provision of the feeding mechanism 80 facilitates the staff to feed the quartz sand to be cleaned into the cleaning frame 51. That is, the staff can pour the quartz sand to be cleaned into the hopper 81, and the quartz sand in the hopper enters the cleaning frame 51 through the bellows 82, which not only facilitates the staff to feed, but also effectively increases the amount of one-time feeding.

[0051] Further, in one embodiment of the present application, Figure 2 and Figure 3 As shown, the above-mentioned quartz sand impurity removal equipment may further include a cleaning assembly 90 , and the cleaning assembly 90 may include a bottom plate 91 , a first conveying roller 92 , a second conveying roller 93 , a mesh belt 94 and a plurality of buckets 95 .

[0052] The bottom plate 91 is sealed and arranged at the bottom end of the second chamber 23, and the second chamber 23 is filled with cleaning liquid. It should be noted that a drain valve (not shown in the figure) is arranged on the bottom plate 91 described in this embodiment.

[0053] The first conveying roller 92 and the second conveying roller 93 are rotatably arranged in the second chamber 23 respectively, and the position height of the second conveying roller 93 is higher than the position height of the first conveying roller 92, wherein the rotating shaft of the second conveying roller 93 passes through the second chamber 23 and is connected to the driven pulley 901, and the driven pulley 901 is connected to the pulley 61 in another transmission mechanism 60 through the second belt 902, and a discharge port 201 is opened on the partition 21 near the second conveying roller 93.

[0054] The mesh belt 94 is sleeved on the first conveying roller 92 and the second conveying roller 93, and multiple buckets 95 are distributed on the mesh belt 94. For example, the multiple buckets 95 can be 7, 8, 9, 10, 11 buckets 95, etc. The specific number of buckets 95 can be selected according to actual conditions and is not limited here.

[0055] It should be noted that the bucket 95 described in this embodiment has a plurality of drainage holes.

[0056] Specifically, when the quartz sand passes through the mesh of the filter 40 and enters the second chamber 23, the cleaning liquid in the second chamber 23 can clean the quartz sand to remove impurities (such as soil and fine dust, etc.) attached to the quartz sand.

[0057] At the same time, the rotating pulley 61 drives the driven pulley 901 to rotate through the second belt 902, and the rotating driven pulley 901 drives the second conveying roller 93 to rotate. The rotating second conveying roller 93 drives multiple buckets 95 to move along the movement trajectory of the mesh belt 94 through the mesh belt 94. The moving bucket 95 digs up the quartz sand in the cleaning liquid. When the bucket 95 moves to the discharge outlet 201, the bucket 95 pours the dug quartz sand into the third chamber 24 and discharges it through the bottom outlet of the third chamber 24.

[0058] As a possible situation, in order to improve the cleaning effect of the quartz sand in the second chamber 23, a plurality of nozzles (not shown in the figure) can be arranged on the inner wall of the second chamber 23, and a water pump (not shown in the figure) can be arranged in the second chamber 23, and the water outlet of the water pump is connected to the plurality of nozzles through a pipe.

[0059] It is understandable that the staff can control the water pump to supply the cleaning liquid to the multiple nozzles, and flush the quartz sand in the second chamber 23 through the nozzles to improve the impurity removal effect on the quartz sand.

[0060] In summary, the quartz sand impurity removal equipment of the embodiment of the present application can automatically clean the filter screen in real time without excessive manual operation, which not only reduces the burden on workers and reduces maintenance costs, but also ensures filtration efficiency.
