Description

Technical Field

[0001] This utility model relates to the field of glass manufacturing technology, and in particular to a sand level display device and a sand screening system. Background Technology

[0002] With the continuous development of industrial production technology, mineral processing technology plays an increasingly important role in mineral processing. Among them, desliming, as the final step in mineral processing, is of great significance for ensuring the quality of refined sand and improving mineral processing efficiency.

[0003] Currently, in mineral processing, desliming is mainly achieved through desliming hoppers for sand level control and discharge. This process typically requires 1-2 operators on-site, whose duties include controlling the sand level in the desliming hopper, monitoring the overflow fine powder, and timely discharge. Operators need to periodically climb stairs to the top of the desliming hopper (approximately 6 meters high) to measure the sand level to ensure the normal operation of the production process.

[0004] However, in the existing technology, due to the large height difference between the discharge position of the desliming hopper and the upper detection position, the operator needs to frequently travel back and forth to different heights to monitor the sand level, which makes the sand level monitoring inefficient and poses a safety hazard, affecting the sand selection efficiency. Utility Model Content

[0005] The main purpose of this utility model is to propose a sand level display device and a sand screening system, which aims to solve the technical problem that, due to the large height difference between the discharge position of the desliming hopper and the upper detection position, operators need to frequently travel back and forth to different heights to monitor the sand level, which results in low sand level monitoring efficiency and safety hazards, affecting sand selection efficiency.

[0006] To achieve the above objectives, this utility model proposes a sand level display device, comprising: A sand hopper has a sand discharge hole at its bottom, a sand discharge valve installed at the sand discharge hole, a sand inlet at its top, and a first sand storage position, a second sand storage position, and a third sand storage position that are arranged sequentially and at intervals from bottom to top inside the sand hopper. A desliming hopper, wherein the desliming hopper is installed above the sand-leaking hopper and is connected to the sand inlet; and, A sand level monitoring device is installed above the desliming hopper and is oriented towards the sand hopper. The sand level monitoring mechanism can monitor the current sand level in the sand hopper, and when the current sand level is located at the first sand storage position, the second sand storage position and the third sand storage position respectively, the sand discharge valve can switch between the sand storage state with the sand discharge hole closed, the first sand discharge state with the sand discharge hole open and the second sand discharge state with the sand discharge hole fully open.

[0007] In one embodiment, the sand level monitoring device includes: Mounting bracket, which is mounted above the desliming hopper; and, A monitor is mounted on the mounting bracket and is positioned facing the sand funnel.

[0008] In one embodiment, the monitor is an ultrasonic monitor.

[0009] In one embodiment, the first sand storage position forms a low sand level, and the sand discharge valve can switch between the sand storage state and the first sand discharge state.

[0010] In one embodiment, the third sand storage position forms a high sand level, which is located above the low sand level, and the sand discharge valve can switch between a first sand discharge state and a second sand discharge state.

[0011] In one embodiment, the sand discharge valve is connected to the sand discharge pipe.

[0012] In one embodiment, the sand level display device further includes an installation platform, on which a support frame is provided, and the sand funnel is installed on the support frame.

[0013] In one embodiment, there are multiple sand level display devices, all of which are arranged sequentially.

[0014] In one embodiment, the sand level display device further includes a controller, which is communicatively connected to the sand level monitoring mechanism and can display the current sand level in the desliming bucket collected by the sand level monitoring mechanism.

[0015] Based on the same technical concept, in a second aspect, this utility model also proposes a sand screening system, including the sand level display device described in the first aspect.

[0016] The technical solution of this utility model involves setting up a sand-leaking hopper, a desliming hopper, and a sand level monitoring mechanism. In use, the bottom of the sand-leaking hopper has a sand discharge hole with a sand discharge valve installed at the hole. The top of the sand-leaking hopper has a sand inlet installed above it, and the desliming hopper is connected to the sand inlet. The sand level monitoring mechanism is installed above the desliming hopper, facing the sand-leaking hopper. This mechanism monitors the current sand level in the desliming hopper. When the current sand level in the desliming hopper is lower than a preset height, the sand discharge valve is closed, putting the sand-leaking hopper into a sand-accumulating state. This allows the utility model to monitor the current sand level in the desliming hopper without requiring operators to frequently travel to different heights for sand level monitoring, improving detection efficiency and safety, reducing safety hazards, and ensuring efficient sand selection.

[0024] This utility model proposes a sand level display device.

[0025] Please see Figure 1 In one embodiment of this utility model, the sand level display device includes a sand hopper 100, a desliming hopper 200, and a sand level monitoring mechanism 300. A sand discharge hole is formed at the bottom of the sand hopper 100, and a sand discharge valve 110 is installed at the sand discharge hole. A sand inlet 120 is formed at the top of the sand hopper 100. A first sand storage position, a second sand storage position, and a third sand storage position are formed inside the sand hopper 100, arranged sequentially and at intervals from bottom to top. The desliming hopper 200 is installed above the sand hopper 100 and deslims... The hopper 200 is connected to the sand inlet 120. The sand level monitoring mechanism 300 is installed above the desliming hopper 200 and faces the sand leakage hopper 100. The sand level monitoring mechanism 300 can monitor the current sand level in the sand leakage hopper 100. When the current sand level is at the first sand storage position, the second sand storage position and the third sand storage position respectively, the sand discharge valve 110 can switch between the sand storage state with the sand discharge hole closed, the first sand discharge state with the sand discharge hole open and the second sand discharge state with the sand discharge hole fully open.

[0026] In one embodiment, the sand level display device includes a sand hopper 100, a desliming hopper 200, and a sand level monitoring mechanism 300 arranged sequentially from bottom to top. The bottom of the sand hopper 100 has a sand discharge hole for discharging sand, and a sand discharge valve 110 that can be controlled to open or close is installed at the sand discharge hole. The top of the sand hopper 100 has a sand inlet 120. The desliming hopper 200 is installed above the sand hopper 100 and is connected to the sand inlet 120, allowing sand in the desliming hopper 200 to enter the sand hopper 100 through the sand inlet 120. The sand level monitoring mechanism 300 is installed above the desliming hopper 200 and faces the sand hopper 100 to achieve real-time monitoring of the sand accumulation height within the desliming hopper 200.

[0027] The sand level display device of this application, by setting a sand level monitoring mechanism 300 above the desliming hopper 200, can monitor the current sand level in the desliming hopper 200 in real time. When the current sand level in the desliming hopper 200 is lower than a preset height, the sand level monitoring mechanism 300 can automatically control the closure of the sand discharge valve 110, so that the sand hopper 100 is in a sand storage state, avoiding excessive sand loss. Specifically, the sand level monitoring mechanism 300 detects the accumulation height of sand in the desliming hopper 200 through a sensor, and converts the detection signal into an electrical signal and transmits it to the controller 600. The controller 600 determines whether the current sand level is lower than the preset height according to a preset sand level threshold, and controls the opening or closing state of the sand discharge valve 110 accordingly.

[0028] The sand level display device of this application uses an automated sand level monitoring mechanism 300 to replace manual monitoring, eliminating the need for operators to frequently travel to different heights to monitor the sand level, thus significantly improving the efficiency of sand level monitoring. At the same time, by avoiding manual climbing operations, safety hazards are effectively reduced. Furthermore, the sand level monitoring mechanism 300 can monitor the sand level status within the desliming hopper 200 in real time and achieve precise control of the sand level by automatically controlling the opening or closing of the sand discharge valve 110, preventing excessive sand loss or accumulation, thereby improving the overall efficiency of the sand selection process.

[0029] By setting up a sand hopper 100, a desliming hopper 200, and a sand level monitoring mechanism 300, the sand hopper 100 has a sand discharge hole at its bottom, and a sand discharge valve 110 is installed at the sand discharge hole. The top of the sand hopper 100 has a sand inlet 120, which is installed above the sand hopper 100 and is connected to the sand inlet 120. The sand level monitoring mechanism 300 is installed above the desliming hopper 200 and faces the sand hopper 100. The sand level monitoring mechanism 300 monitors the current sand level in the desliming hopper 200. When the current sand level in the desliming hopper 200 is lower than a preset height, the sand discharge valve 110 is closed, so that the sand hopper 100 is in a sand-accumulating state. This allows the present invention to monitor the current sand level in the desliming hopper 200 without requiring operators to frequently travel back and forth to different heights to monitor the sand level, thus improving detection efficiency and safety, reducing safety hazards, and ensuring sand selection efficiency.

[0030] In one embodiment, the sand level monitoring mechanism 300 includes a mounting frame 310 and a monitor 320. The mounting frame 310 is mounted above the desliming hopper 200, and the monitor 320 is mounted on the mounting frame 310 and is positioned facing the sand hopper 100.

[0031] Specifically, the mounting frame 310 is fixed above the desliming hopper 200 using a bracket structure, and the monitor 320 is installed on the mounting frame 310 by bolt connection, so that the monitor 320 can stably face the inside of the desliming hopper 200 to monitor the sand level.

[0032] It should be specifically and clearly stated that the monitor 320 is an ultrasonic monitor 320. In this embodiment, the monitor 320 used in the specific implementation process is preferably based on the principle of ultrasonic monitoring for sand level monitoring. This embodiment only applies it and does not improve its design, so it will not be described in detail here.

[0033] More specifically, in this embodiment, when the desliming hopper 200 is in operation, the monitor 320 is also in operation. At this time, the monitor 320 monitors the sand and gravel storage in the desliming hopper 200 in real time. When the sand and gravel storage in the desliming hopper 200 is at the first sand storage position, the sand discharge valve 110 is closed, so that the sand hopper 100 is in the sand storage state. When the monitor 320 detects that the sand and gravel height in the sand hopper 100 is higher than the third sand storage position, the sand discharge valve 110 is fully opened to discharge the sand and gravel in the sand hopper 100. When the sand and gravel height in the sand hopper 100 is lower than the third sand storage position but higher than the second sand storage position, the sand discharge valve 110 switches from the second sand discharge state with the sand discharge hole fully open to the first sand discharge state with the sand discharge hole open, and continues to perform sand discharge operation. When the sand and gravel height in the sand hopper 100 is lower than the first sand storage position, the sand discharge valve 110 closes the sand discharge hole and the sand hopper 100 switches to the sand storage state to store sand.

[0034] Of course, the specific structure of the example ultrasonic device is as follows: a fixed bracket is set near the central cylinder of the desliming hopper, and an ultrasonic sensor is installed. The installation position is preferably in the area sensitive to sand level fluctuations to ensure that the ultrasonic beam can be projected vertically onto the sand surface. The sensor is waterproof and dustproof, adapting to the harsh environment of the mineral processing site.

[0035] The principle of ultrasonic testing is as follows: Utilizing the difference in sound wave reflection characteristics caused by the density difference between quartz sand and water, an ultrasonic sensor emits high-frequency sound waves. These sound waves are reflected when they reach the sand surface, and the sensor receives the echo and calculates the time difference. The formula is: H = 0.5vt. Where (H) is the sand height, (v) is the speed of sound in the medium, and (t) is the echo time.

[0036] The example ultrasonic sensor may be, but is not limited to, the example model ultrasonic sensor: HC-SR04, US-026 (or US-100), and MB1010 LV-MaxSonar-EZ series, etc.

[0037] In one embodiment, a low sand level 130 is formed at the first sand storage position, and the sand discharge valve 110 can switch between a sand storage state and a first sand discharge state.

[0038] Specifically, the sand discharge valve 110 can switch between two working states according to the change in the sand accumulation height in the sand hopper 100: when the sand accumulation height in the sand hopper 100 is lower than the low sand level 130, the sand discharge valve 110 is in the closed state; when the sand accumulation height is higher than the low sand level 130, the sand discharge valve 110 switches to the open state. This allows the present invention to achieve the function of sand storage during use.

[0039] In one embodiment, a high sand level 140 is formed at the third sand storage position, which is located above the low sand level 130, and the sand discharge valve 110 can switch between a first sand discharge state and a second sand discharge state.

[0040] Specifically, the sand discharge valve 110 can be adjusted between a fully open state and an open state according to the change in the sand accumulation height in the sand hopper 100: when the sand accumulation height in the sand hopper 100 exceeds the high sand level 140, the sand discharge valve 110 is in the fully open state; when the sand accumulation height is between the high sand level 140 and the low sand level 130, the sand discharge valve 110 is in the open state.

[0041] In one embodiment, the sand discharge valve 110 is connected to the sand discharge pipe 700.

[0042] In this embodiment, by connecting the sand discharge valve 110 to the sand discharge pipe 700, the present invention can discharge the sand collected in the sand funnel 100, thus ensuring the collection efficiency of the sand.

[0043] In one embodiment, the sand level display device further includes a mounting platform 400, on which a support frame 500 is mounted, and a sand funnel 100 is mounted on the support frame 500. Multiple sand level display devices are arranged sequentially.

[0044] In one embodiment, the sand level display device further includes a controller 600, which is communicatively connected to the sand level monitoring mechanism 300. The controller 600 can display the current sand level in the desliming bucket 200 collected by the sand level monitoring mechanism 300.

[0045] Specifically, the controller 600 receives and processes the current sand level data collected by the sand level monitoring mechanism 300 within the desliming hopper 200, and displays the sand level information in real time on a display screen. This allows the present invention to display the sand level status in real time using the controller 600, effectively improving real-time performance.

[0046] Based on the same technical concept, in a second aspect, this utility model also proposes a sand screening system that uses the sand level display device described in the first aspect.

[0047] Furthermore, the sand screening system provided in this application can solve the technical problem that, due to the significant height difference between the discharge position of the desliming hopper and the upper detection position, operators need to frequently travel back and forth to different heights to monitor the sand level. This results in low sand level monitoring efficiency and safety hazards, affecting sand selection efficiency. Compared with the prior art, the beneficial effects of the sand screening system provided in this application are the same as those of the sand level display device provided in the above embodiments, and other technical features of the sand screening system are the same as those disclosed in the methods of the above embodiments, and will not be repeated here.

[0048] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
