[0023] In terms of mineral resource development, raw ore refers to unprocessed natural ore, which is rich in mineral components. In order to make full use of these mineral resources and improve resource utilization efficiency, we continue to explore and study the processing and utilization technologies of various ores. As a natural sand source, sea sand has the advantages of wide sources and low cost. It contains high salt and impurities. With the rapid development of the construction industry, the demand for sea sand is increasing. Sea sand is sand and gravel in the sea. It is pure natural and is formed by seawater scouring, rolling, collision and grinding. In addition to silicon dioxide, sea sand also contains a small amount of chloride ions, feldspar, calcium, magnesium, mica, etc. As the second largest marine mineral after oil and natural gas, sea sand has many uses and is widely used in construction, roads and concrete production. The production process of sea sand includes sand mining, sand washing and sand screening. The traditional sea sand production process has problems such as low production efficiency, high energy consumption and environmental pollution. It cannot meet the demand for high-quality sea sand in the modern construction industry, and there is a problem of low screening efficiency for sea sand.

[0024] See also Figure 1 and Figure 2In order to solve the above problems, the embodiment of the present application provides a sea sand screening equipment 10, including a raw material bin 1, a feeder 2, a vibrating screen 4, a water circulation device and a material bin 8 to be ground, the raw material bin 1 is used to feed the sea sand to be cleaned into the feeder 2 for uniform vibration, the feeder 2 feeds the sea sand to be cleaned after uniform vibration into the vibrating screen 4 through a conveyor belt 3, the vibrating screen 4 is provided with a spray device 10 to clean the sea sand to be cleaned, the vibrating screen 4 is used to screen the sea sand to be cleaned into oversize and undersize, the bottom of the vibrating screen 4 is provided with an undersize pool, the undersize enters the undersize pool, a discharging conveyor belt 7 is arranged between the vibrating screen 4 and the material bin 8 to be ground, the oversize enters the material bin 8 to be ground through the discharging conveyor belt 7, and the undersize pool is connected to the spray device 10 through the water circulation device.

[0025] In the sea sand screening device 10, sea sand enters the raw material bin 1. Further, the sea sand to be cleaned in the raw material bin 1 is fed into the feeder 2, which is also called the feeder. The feeder 2 can feed the processed or unprocessed sea sand to the vibrating screen 4 continuously and evenly, and can realize the automation of sea sand feeding. The feeder 2 can vibrate the sea sand evenly, and the vibrated sea sand is fed into the vibrating screen 4 through the conveyor belt 3. The vibrating screen 4 is provided with a spray device 10, which can spray the sea sand to be cleaned. The vibrating screen 4 is used for cleaning, and the sea sand is screened into the screened material and the screened material. An under-screen pool is provided at the bottom of the vibrating screen 4, and the screened material can fall into the under-screen pool, and the screened material can be sent to the material bin 8 to be grinded by the discharging conveyor belt 7. The under-screen pool is connected with the spraying device 10 through the water circulation device.

The screening efficiency is high, and the sea sand can be separated quickly and accurately, thereby improving the working efficiency of sea sand screening.

[0026] In some embodiments, the vibrating screen 4 works by using the reciprocating vibration generated by the excitation of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce a plane gyratory vibration, while the lower rotating weight causes the screen surface to produce a conical gyratory vibration. The combined effect causes the screen surface to produce a compound gyratory vibration. The vibrating screen 4 can screen the crushed quartz sand and remove oversized or undersized particles. In some embodiments, the vibrating screen 4 can use a single-layer linear vibrating screen. The single-layer linear vibrating screen relies on the vibration motor to generate source power, and the material on the screen is thrown up while moving forward in a straight line. The material falls evenly from the feeder 2 to the inlet of the vibrating screen 4, and then through the multi-layer screen to produce different specifications of upward screening, downward screening, and finally screened out from outlets of different specifications. The single-layer linear vibrating screen has a simple structure and high screening efficiency. In some embodiments, the single-layer linear vibrating screen includes a screen body, a vibrating motor, and a supporting device. In some embodiments, the screen body includes a screen plate and a screen mesh structure. The screen plate is tilted downward from the feeding sand falling position toward the other end of the screen plate diameter. The end of the screen plate is provided with a waste outlet. The screen plate is provided with a downwardly tilted discharge port.

In some embodiments, the vibration screen 4 can be further made to form a uniform and stable material layer during the sea sand screening process by accurately calculating and adjusting the vibration frequency, amplitude, and vibration direction angle of the vibration motor, thereby improving the screening efficiency and accuracy. In some embodiments, the supporting device in the vibrating screen 4 can be a spring supporting device, which is convenient for adjusting the screen plate. At the same time, the spring supporting device is convenient for the replacement and maintenance of the spring, and the main parts of the device are flexible and easy to install.

[0027] See also Figure 1The vibrating screen 4 is provided with a spraying device 10, which can wash the sea sand. The spraying device 10 can spray fresh water or inject fresh water onto the sea sand in the vibrating screen 4. In some embodiments, the spraying water surface can be higher than the sea sand surface. The fresh water seeps downward in the sea sand and fills the gaps between the sand particles. The sea sand to be cleaned is cleaned and screened by the spraying device 10 into oversize and undersize. The oversize is sent to the material bin 8 to be ground through the chute 13 and the discharging conveyor belt 7. In some embodiments, the chute 13 is used to transport the oversize, and the oversize can be transported from a high place to a low place. Its internal surface is smooth, which can make the material slide down automatically under the guidance of gravity and the inner wall. The design of the chute 13 takes into account the particle size and flow rate of the oversize to ensure that the oversize can be smoothly transported to the material bin 8 to be ground. In some embodiments, the chute 13 and the discharge conveyor belt 7 can be connected mechanically. Specifically, the steel wire ropes at both ends of the discharge conveyor belt 7 are bolted to the aluminum plate of the chute 13 to achieve the connection effect. In some embodiments, the chute 13 and the discharge conveyor belt 7 can be connected by hot melt. The two ends of the discharge conveyor belt 7 are directly bonded to the aluminum plate of the chute 13 using hot melt adhesive to achieve the connection effect. The installation is simple and can reduce wear and noise. In some embodiments, the spray device 10 is provided with a spray pipe, which is usually a drain pipe and is used in conjunction with the main pipeline and the spray head. In some embodiments, the coating of the spray pipe can be made of epoxy resin. Epoxy resin is a thermosetting resin with good antistatic properties, and also has the advantages of good stability and small curing shrinkage. The water sprayed from the spray pipe falls into the mortar pool 5 after washing the sea sand. In some embodiments, two spray water pipes can be arranged on the upper layer of the screen plate, and the spray pipes are arranged in four groups in total. The spray pipes are arranged in four groups, which helps to make the sea sand more evenly distributed on the screen plate. During the spraying process, the accumulation and congestion of the raw materials during the screening process are reduced, thereby improving the screening efficiency of the sea sand screening device 10. At the same time, the impact and friction of the sea sand sprayed by the spray device 10 on the screen are reduced, further improving the service life of the screen.

[0028] In some embodiments, the vibrating screen 4 further includes a control system, the control system is provided with a monitor, and the control system may adopt an intelligent control system, and the monitor is used to monitor the operating state and screening effect of the vibrating screen 4 in real time. By analyzing the data generated by the control system, the control system can automatically adjust the vibration parameters, thereby completing the intelligent control of the screening process, thereby helping to reduce the energy consumption of the sea sand screening equipment 10, reduce maintenance costs, and improve screening efficiency.

[0029] See also Figure 2The under-screen pool includes a mortar pool 5 located at the bottom of the vibrating screen 4. The mortar pool 5 can be used to store and purify sea sand. Its main function is to remove some impurities in the sea sand to screen the sea sand. The under-screen pool is connected to the spray device 10 through a water circulation device. In some embodiments, the water circulation device includes a separation box 11, a desludging bucket 12, and an obstructed sedimentation machine 9. The under-screen pool also includes a slurry pump 6 arranged at the outlet of the mortar pool 5 and a separation box 11 arranged at the outlet of the slurry pump 6. The slurry pump 6 is a machine that increases the energy of the solid-liquid mixed medium by the centrifugal force of the rotation of the pump impeller. It is a device that converts electrical energy into kinetic energy and potential energy of the medium. Under the action of centrifugal force, the under-screen material is thrown from the center of the impeller of the slurry pump 6 to the outer edge and obtains energy, leaving the outer edge of the impeller at high speed and entering the volute pump casing. In the volute pump casing, the liquid slows down due to the gradual expansion of the flow channel, and converts part of the kinetic energy into static pressure energy, and finally flows into the discharge pipe at a higher pressure and is sent to the separation box 11. In some embodiments, the under-screen pool includes two slurry pumps 6, the inlet of each slurry pump 6 is connected to the mortar pool 5, and the outlet is connected to the separation box 11. The slurry pump 6 is arranged at the lower part of the vibrating screen 4, and the mixture of water and sea sand can be transported to the dehydration equipment and the sedimentation tank for effective separation. In some embodiments, a slurry pump 6 and its supporting equipment are arranged at the lower part of the vibrating screen 4, wherein the slurry pump 6 can use a slurry pump 6 with a model of ZBE200-150-500R, and its motor power is 110KW. In some embodiments, the slurry pump 6 can use a slurry pump 6 with a model of YQZD150-100-400R, and its motor power is 37KW. In some embodiments, the two slurry pumps 6 can be switched between the above two models to reduce energy consumption and reduce costs while screening sea sand.

[0030] The slurry pump 6 is used to transport the ore separation box 11, which has the function of grinding and selecting. In some embodiments, the ore separation box 11 is provided with a discharge hopper, and the sea sand in the ore separation box 11 can be evenly discharged to the desludging hopper 12 through the discharge hopper. In some embodiments, a valve is provided at the outlet of the ore separation box 11, and the valve can control the sea sand entering the desludging hopper 12. The valve controls the sea sand to enter the desludging hopper 12 for dehydration. The desludging hopper 12 uses centrifugal force to screen different sand particles in the sea sand. In some embodiments, the desludging hopper 12 includes a bucket body, a rotor, a motor, a reducer and a transmission shaft, wherein the bucket body is the main part of the desludging hopper 12, which is usually made of steel plate and has strong durability and carrying capacity. The rotor is the core part of the desludging hopper 12, and there are many curved leaves inside the rotor. When the rotor rotates at high speed, the centrifugal force will separate the different sand particles of the sea sand. Furthermore, the sea sand after dehydration and concentration in the desludging bucket 12 enters the obstructed sedimentator 9, and the obstructed sedimentator 9 quickly separates the impurities such as suspended matter in the wastewater through sedimentation separation, so that the wastewater can be recycled, and then enters the single-layer linear vibrating screen for use through valve control, completing the screening process of the screened material. In this process, the sea sand is processed into a primary quartz sand product through crushing, grinding, screening, grading and other processes. This process optimizes the traditional process of sea sand screening by passing the sea sand through the raw material bin 1, feeder 2, vibrating screen 4, water circulation device and grinding bin 8 at one time, which can improve the production efficiency of sea sand screening, thereby improving the working efficiency of the sea sand screening equipment 10.

[0031] See also Figure 1 and Figure 2In the process of screening sea sand, first, the sea sand enters the raw material warehouse 1, and the sea sand to be cleaned in the raw material warehouse 1 is sent to the feeder 2. The feeder 2 feeds the processed or unprocessed sea sand to the vibrating screen 4 continuously and evenly to realize the automation of sea sand feeding. The feeder 2 vibrates the sea sand evenly, and the vibrated sea sand is sent to the vibrating screen 4 through the conveyor belt 3. The spray device 10 in the vibrating screen 4 can clean the sea sand to be cleaned, wherein the spray device 10 can be provided with different numbers of spray pipes according to the needs to meet different screening requirements. The vibrating screen 4 also includes a control system, and the control system is provided with a monitor. The control system can adopt an intelligent control system, and the monitor is used to monitor the operating status and screening effect of the vibrating screen 4 in real time. The data generated by the control system is analyzed to realize that the control system automatically adjusts the vibration parameters, and then completes the intelligent control of the screening process, which helps to reduce the energy consumption of the sea sand screening equipment 10, reduce maintenance costs, and improve screening efficiency. Furthermore, the vibrating screen 4 screens the sea sand into oversize and undersize, wherein the oversize can be sent to the grinding material bin 8 by the discharging conveyor belt 7, and the oversize and undersize enter different processes respectively. An undersize pool is arranged at the bottom of the vibrating screen 4, and the undersize can fall into the undersize pool. The undersize pool is connected to the spraying device 10 through a water circulation device, and the sea sand is screened by the water circulation device. The undersize pool includes a mortar pool 5 located at the bottom of the vibrating screen 4, and the water circulation device includes a separation box 11, a desludging bucket 12 and an obstructed sedimentation machine 9. The undersize pool also includes a slurry pump 6 arranged at the outlet of the mortar pool 5 and a separation box 11 arranged at the outlet of the slurry pump 6. The undersize pool includes two slurry pumps 6, and the inlet of each slurry pump 6 is connected to the mortar pool 5, and the outlet is connected to the separation box 11. The slurry pump 6 is arranged at the lower part of the vibrating screen 4, which can The mixture of water and sea sand is transported to the dewatering equipment and the sedimentation tank for effective separation, and then transported to the separation box 11 through the slurry pump 6. A valve is provided at the outlet of the separation box 11, and the valve can control the sea sand entering the desludging bucket 12. The valve controls the sea sand to enter the desludging bucket 12 for dehydration. The sea sand after dehydration and concentration in the desludging bucket 12 enters the blocked sedimentator 9. The blocked sedimentator 9 quickly separates impurities such as suspended matter in the wastewater through sedimentation separation, so that the wastewater can be recycled. The wastewater is then controlled by the valve to enter the single-layer linear vibrating screen for use, completing the screening process of the screened material. By optimizing the traditional process of sea sand screening, the sea sand to be cleaned in the raw material bin 1 is finally transferred to the grinding bin 8 after being screened. The screening efficiency is high, and the sea sand can be separated quickly and accurately, thereby improving the working efficiency of sea sand screening.
