[0002] Quartz sand must be made into products for different purposes according to the requirements of different industries. Before that, it must be beneficiated. Purifying materials through beneficiation methods is to remove harmful impurities in the ore at a lower separation cost and improve the purity of the target mineral. For quartz ore, the target mineral is quartz, and the impurities are feldspar, mica, chlorite, clay minerals, rock debris and iron-containing impurities. In the quartz sand beneficiation process, the hindered settler is an important equipment used to improve the classification efficiency and control the feed concentration and ore volume. In the operation of the hindered settler, once the nozzle is blocked, it will affect the use of the hindered settler. In the prior art, the problem of nozzle blockage is usually solved by flushing the nozzle. However, since the flushing nozzle needs to work in the quartz sand beneficiation environment, if the foreign matter or sand and gravel on the inner wall of the nozzle is not cleaned in time, it will cause dirt to accumulate, resulting in sand and gravel dirt siltation precipitation and nozzle blockage, which will affect the work efficiency of quartz sand beneficiation.

[0027] The quartz sand beneficiation process is mainly to purify and remove a small amount of impurities in the quartz sand, and obtain a high-difficulty separation technology for refined quartz sand or high-purity quartz sand. The quartz sand purification processes at home and abroad mainly include water washing, graded desludging, scrubbing, magnetic separation, flotation, acid leaching, microbial leaching, etc. In the quartz sand beneficiation process, the hindered settler is an important equipment used to improve the classification efficiency and control the feed concentration and ore volume. The mixture of sand and water is fed from the top through the feed pipe and moves downward in the cylinder under the action of gravity. There is a porous water spray turbulence plate at the bottom of the cylinder. The new water fed rises evenly. The rising water flow interacts with the descending solid particles to gradually form a fluidized bed. Particles of different particle sizes will fall down or move upward at the hindered settling velocity under the volume concentration. Hindered settling is the first type of sedimentation phenomenon, which is characterized by the action between the particles being sufficient to hinder the sedimentation of adjacent particles. The particles maintain a fixed position with each other, and the particle group as a whole, that is, sinks in layers. The sedimentation rate is related to the concentration and characteristics of the particles. Activated sludge liquid is generally such a sediment. In the hindered settler, a mixture of sand and water is fed from the top through the feed trough, and moves downward in the cylinder under the action of gravity. There is a multi-hole water spray plate at the bottom of the cylinder. The rising water flow interacts with the descending solid particles to gradually form a fluidized bed. Particles of different particle sizes will fall downward or move upward at the hindered drop rate under the volume concentration. With the help of an electronic pressure sensor, the pressure condition of the fluidized bed can be measured and the opening of the discharge valve can be automatically adjusted to ensure the required separation and classification. In the operation of the hindered settler, once the nozzle is blocked, it will affect the use of the hindered settler. In the prior art, the nozzle is generally flushed to prevent the nozzle from being blocked. However, since it works in a quartz sand beneficiation environment, if foreign matter or sand and gravel on the inner wall of the nozzle are not cleaned in time, it will cause dirt to accumulate and cause the nozzle to be blocked.

[0028] refer to Figure 1 and Figure 2 In order to solve the above problems, the embodiment of the present application provides a flushing nozzle 10, including: a nozzle assembly, the nozzle assembly includes a nozzle body 11; an anti-blocking assembly 20, the anti-blocking assembly 20 includes an annular frame 21 fixed on the cavity wall of the inner cavity of the nozzle body 11, a horizontal plate 22 fixed on the annular frame 21, a fan blade 28 rotatably connected to the horizontal plate 22, and a curved rod 25 connected to the fan blade 28 and rotating synchronously, the curved rod 25 is in contact with the cavity wall of the inner cavity, and the rotation axis direction of the fan blade 28 is parallel to the axial direction of the nozzle body 11.

[0029] In the flushing nozzle 10, the nozzle assembly includes a nozzle body 11, and the nozzle body 11 can be a hollow cone structure. The anti-blocking assembly 20 includes an annular frame 21 fixed on the inner wall of the nozzle body 11 and a horizontal plate 22 fixed on the annular frame 21. The anti-blocking assembly 20 is used to prevent the nozzle body 11 from being accumulated with foreign matter or sand and gravel, and can prevent the flushing nozzle from being blocked. Specifically, the annular frame 21 and the horizontal plate 22 are used to fix the position of the entire anti-blocking assembly 20. The annular frame 21 can be set as an annular structure that fits the inner wall of the nozzle body 11. The annular frame 21 can play a fixing role. The horizontal plate 22 connects the annular frame 21. The horizontal plate 22 is connected to the inner wall of the nozzle body 11 through the annular frame 21, and the horizontal plate 22 plays the role of connecting the fan blades 28. The nozzle assembly also includes a fan blade 28 rotatably connected to the horizontal plate 22 and a curved rod 25, the fan blade 28 is connected to the horizontal plate 22 and is disposed inside the nozzle body 11, the curved rod 25 is a curved rod, the curved rod 25 can be connected to the fan blade 28, and the curved rod 25 can rotate synchronously with the fan blade 28. In some embodiments, the curved rod 25 fits with the cavity wall of the inner cavity, and the fit of the curved rod 25 with the wall of the inner cavity can make the curved rod 25 fully contact the inner cavity of the nozzle body 11, so as to more thoroughly clean the foreign matter or sand and gravel in the inner cavity of the nozzle body 11, so as to achieve the effect of cleaning the dirt inside the nozzle, and to prevent the nozzle from being blocked. In some embodiments, the rotation axis direction of the fan blade 28 is parallel to the axial direction of the nozzle body 11. When the water flow pushes the fan blade 28 to rotate, the fan blade 28 drives the curved rod 25 to rotate. The curved rod 25 can contact the cavity surface of the inner cavity of the nozzle body 11 to clean the dirt on the surface. The pressure during water spraying is used to achieve self-rotation, and the inside of the nozzle body 11 is automatically cleaned to avoid the blockage of the nozzle body 11 caused by the accumulation of sand and dirt, thereby improving the efficiency of quartz sand beneficiation.

[0030] In some embodiments, the cross plate 22 can be set as a cross structure, and the cross plate 22 is connected to the inside of the nozzle body 11 through the annular frame 21. The cross structure can increase the stability of the connection between the cross plate 22 and the annular frame 21, thereby improving the stability of the connection between the anti-blocking component 20 and the nozzle body 11, which is conducive to improving the efficiency of quartz sand beneficiation. In some embodiments, the cross plate 22 can also be set as a strip structure, and the annular frame 21 is set along the inner side of the nozzle body 11. The cross plate 22 of the strip structure is connected to the annular frame 21 and can be stably connected to the nozzle body 11. In some embodiments, the cross plate 22 can adopt an arc rod. Specifically, the whole of the cross plate 22 is set to the side of the inner cavity opening of the nozzle body 11, that is, the direction of the inner thread side, and is set to an arched structure in this direction. The cross bar 22 is set to the above arc rod structure to improve the support force of the cross bar 22. When the water flow impacts the cross bar 22 for a long time, the arc rod structure has the advantage of not being easily deformed, thereby increasing the service life of the flushing nozzle 10. In some embodiments, a circle of stepped surfaces may be provided on the wall surface of the inner cavity of the nozzle body 11 , and the stepped surfaces are used to form an annular ring to facilitate the disassembly and maintenance of the flushing nozzle 10 .

[0031] See also Figure 2In some embodiments, the anti-blocking assembly 20 includes an annular sleeve 23 fixed on the horizontal plate 22 and a circular shaft 29 that penetrates and rotatably connects the annular sleeve 23. The annular sleeve 23 is used to connect the circular shaft 29. The annular sleeve 23 is connected to the side of the horizontal plate 22 away from the inner cavity of the nozzle body 11. The circular shaft 29 is used to connect the fan blade 28. The fan blade 28 is connected to the side of the circular shaft 29 and is located above the annular sleeve 23. The operating principle of the fan blade 28 is to use the Bernoulli principle. By using the angle of attack or elevation of the fan blade 28 itself, a local vacuum can be formed above the fan blade 28. Due to the pressure difference, the air above the fan blade 28 is sucked into the bottom of the fan blade 28, generating air flow and forming a forced airflow. The nozzle body 11 can be connected to a water supply device, such as a water pipe, and the water supply device can spray water to clean the quartz sand, thereby realizing the water supply function for flushing the nozzle 10. When the water flow contacts the fan blade 28, the kinetic energy of the water flow is converted into the kinetic energy of the fan blade 28, and the kinetic energy of the fan blade 28 can be partially converted into the mechanical energy of the curved rod 25 through the circular shaft 29. In some embodiments, the fan blade 28 is a curved sheet structure. In some embodiments, the fan blade 28 can adopt a forward curved type, bending forward along the running direction of the fan blade 28. In some embodiments, the fan blade 28 can adopt a backward curved type, that is, bending backward along the running direction of the fan blade 28. In some embodiments, the number of the fan blade 28 is multiple, and the provision of multiple fan blades 28 can increase the contact area between the fan blade 28 and the water flow. In some embodiments, the fan blade 28 can be symmetrically arranged. When flushing the nozzle, the water flow can push the blade 28, and the blade 28 rotates and is connected to the circular shaft 29 of the annular sleeve 23, so that the blade 28 can rotate in the nozzle body 11, and the curved rod 25 is connected to the bottom end of the circular shaft 29 so that the curved rod 25 is connected to the nozzle body 11 through the circular shaft 29, and the curved rod 25 can contact the cavity surface of the inner cavity of the nozzle body 11 to clean the dirt on the surface of the inner cavity. In the above process, the process of the blade 28 driving the curved rod 25 to rotate can be realized without a power supply device, and the pressure during the water spraying is cleverly used to make the blade 28 and the curved rod 25 rotate. In some embodiments, the water flow can use a water flow high-pressure pump. When the water flow is pumped into the nozzle body 11 at high pressure, the water flow can impact the blade 28, and the blade 28 impacted by the water flow rotates. When the blade 28 rotates, it drives the circular shaft 29 connected to the annular sleeve 23 to rotate, and the rotation of the circular shaft 29 can drive the curved rod 25 to rotate. In some embodiments, a cleaning brush 26 is provided on the surface of the curved rod 25, and the cleaning brush 26 is in contact with the wall of the inner cavity. The cleaning brush 26 can scrape and clean the inside of the nozzle body 11. The rotation of the curved rod 25 can drive the cleaning brush 26 to scrape and clean the sand and dirt on the wall of the inner cavity of the nozzle body 11. This process can make full use of the pressure generated by the nozzle when spraying water, and can effectively avoid dirt or sand and gravel precipitation on the inner wall of the nozzle body 11, and can avoid nozzle clogging during quartz sand beneficiation.

When the circular shaft 29 rotates along the annular sleeve 23, the first baffle 24 can be attached to the top surface of the annular sleeve 23, and the second baffle 27 is located below the annular sleeve 23. The first baffle 24 and the second baffle 27 can make the position of the annular sleeve 23 relatively fixed and rotate around the circular shaft 29, thereby fixing the annular sleeve 23 in the axial direction of the circular shaft 29. In some embodiments, the first baffle 24 and the second baffle 27 can be set as a metal sheet structure, and the first baffle 24 and the second baffle 27 can be set as a circular shape. In some embodiments, the fan blades 28 are detachably connected to the circular shaft 29 via threads. In some embodiments, a threaded structure can be set on the circular shaft 29, and the fan blades 28 are connected to the side of the circular shaft 29. The fan blades 28 can be set to a threaded design that matches the threaded structure on the circular shaft 29, so that the fan blades 28 and the circular shaft 29 can be detachably connected via threads, which is easy to operate. The detachable connection facilitates the installation and removal of the fan blades 28, facilitates the cleaning and repair of the flushing nozzle 10, and increases the operability of the flushing nozzle 10.

[0033] In some embodiments, the flushing nozzle 10 further includes an adjustment component 30, and the fan blades 28 can rotate under the drive of the water flow. The rotation of the fan blades 28 can play a role in automatically cleaning the inside of the nozzle, and can prevent the blockage of the flushing nozzle caused by the precipitation of sand, dirt and sludge. At the same time, the rotation of the fan blades 28 can drive the curved rod 25 to contact the inner cavity of the nozzle body 11. The flushing nozzle 10 is provided with an adjustment component 30, and the adjustment component 30 can lock the fan blades 28 at any desired angle position, so that the angle of the fan blades 28 is not limited to a fixed angle.

In the process of rotating the threaded barrel 32, the threaded barrel 32 is threadedly advanced, and the threaded barrel 32 drives the annular plate 35 to press the circular plate 33, so that the positioning is completed. The user rotates the threaded barrel 32 to lock the fan blade 28 at any desired angle position, thereby further meeting the user's needs.

In some embodiments, when the flushing nozzle 10 is used, the nozzle is threadedly connected through the internal thread 12 of the nozzle body 11, and the nozzle can spray water to clean the quartz sand. When the water flow enters the flushing nozzle 10, the water flow can push the fan blade 28, and the fan blade 28 rotates and is connected to the circular shaft 29 of the annular sleeve 23, so that the fan blade 28 can rotate in the nozzle body 11, and the fan blade 28 can make the quartz sand flow more smoothly, and the water flow can impact the surface of the quartz sand to flush out impurities. A water outlet is provided at the tip of the nozzle body 11. Quartz sand raw materials are installed inside the nozzle body 11. The water supply device can spray water. Under the flushing action of the water flow, the fan blades 28 rotate to clean the quartz sand. The flushed water can flow out of the flushing nozzle 10 through the water outlet. At the same time, since the flushing nozzle 10 also includes an adjustment component 30, the adjustment component 30 can lock the fan blades 28 at any desired angle position, so that the angle of the fan blades 28 is not limited to a fixed angle. The adjustment component 30 is provided at one end of the fan blades 28 to meet the different needs of users for the flushing nozzle 10. Specifically, the adjustment assembly 30 includes a first round rod 31 fixed at one end of the fan blade 28, a threaded barrel 32 fitted with the first round rod 31, and an annular plate 35 fixed on one side of the threaded barrel 32. In some embodiments, the first round rod 31 passes through the annular plate 35, a second round rod 34 is fixed to the side of the circular shaft 29, and a threaded disk 35 is fixed to one end of the second round rod 34.

In the process of rotating the threaded barrel 32, the threaded barrel 32 is threadedly advanced, and the threaded barrel 32 drives the annular plate 35 to press the circular plate 33, so that the positioning is completed. The user rotates the threaded barrel 32 to lock the fan blade 28 at any desired angle position, thereby further meeting the user's needs. Furthermore, the fan blades 28 drive the curved rod 25 to rotate. Since the curved rod 25 is connected to the bottom end of the circular shaft 29, the curved rod 25 is connected to the nozzle body 11 through the circular shaft 29. A cleaning brush 26 is provided on the curved rod 25, which increases the friction between the curved rod 25 and the inside of the nozzle body 11. Through the contact between the cleaning brush 26 and the inside of the nozzle body 11, the inside of the nozzle body 11 can be scraped and cleaned to clean the sand and dirt on the inner wall of the nozzle body 11, thereby avoiding the situation where the sand and dirt are accumulated and precipitated to cause blockage of the nozzle, thereby improving the efficiency of quartz sand beneficiation.
