Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand pickling, in particular to a quartz sand pickling and purification device. Background Art

[0002] Quartz sand is mainly composed of quartz (SiO2) and usually appears as transparent or translucent particles. Quartz sand is usually obtained through open-pit mining. After mining, it needs to go through processing steps such as crushing, screening, and pickling.

[0003] The surface of quartz sand may contain metal oxides such as iron and aluminum, or organic matter attached to the surface of quartz sand, such as impurities and pollutants such as grease and clay, which affect the purity and quality of quartz sand. Improving transparency and effectively improving the chemical properties of quartz sand.

[0004] However, during the pickling process of quartz sand, the pickling solution cannot be replaced and its concentration cannot be effectively controlled, resulting in unsatisfactory pickling results and even damage to the quartz sand. The pickling process usually requires temperature control, and too high or too low a temperature will affect the pickling effect. After the quartz sand is pickled, the acid remaining on the surface of the quartz sand needs to be cleaned. However, during the cleaning process, the quartz sand cannot be evenly and effectively contacted with the cleaning water, resulting in incomplete cleaning. After cleaning, it is difficult to separate from the cleaning water, causing a large amount of quartz sand to be discharged with the cleaning water, resulting in waste of quartz sand. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a quartz sand acid leaching and purification device which integrates pickling, heating, transfer and cleaning and operates automatically in an integrated manner in view of the deficiencies in the prior art.

[0006] The technical problem to be solved by the utility model is achieved through the following technical solution: a quartz sand pickling and purification device, comprising a spiral pickling tank arranged obliquely, a pickling liquid storage tank provided above the spiral pickling tank, a pickling pipe for guiding the flow of the pickling liquid provided at the bottom of the pickling liquid storage tank, the pickling pipe being arranged along the length direction of the spiral pickling tank, and high-pressure nozzles uniformly distributed along the length direction of the pickling pipe; the high-pressure nozzles make the automatic supply and distribution of the pickling liquid more uniform, and the pickling liquid contacts the quartz sand more fully.

[0007] The spiral pickling tank features a feed port for quartz sand at the bottom of the tank, a pickling liquid outlet at the bottom of the tank, and a pickling liquid outlet assembly. Several parallel heating components are installed on the outer wall of the spiral pickling tank. A discharge port is located at the bottom of the tank at the top of the tank, with a cleaning mechanism located directly below the discharge port. The heating components help maintain the optimal temperature of the pickling liquid, promoting chemical reactions and increasing the purification rate. Quartz sand is rapidly transferred from the feed port to the discharge port, while pickling occurs simultaneously, reducing acid waste. Unreacted acid is recovered through efficient cleaning, reducing the risk of environmental pollution.

[0008] The cleaning mechanism comprises an upwardly open cleaning tank, which houses a mesh trough. The upper end of the trough houses a collection port, directly opposite the discharge port. A spray assembly is located above the collection port. A stirring assembly is circumferentially located between the trough and the cleaning tank. This stirring assembly ensures turbulent flow of the cleaning fluid, thoroughly mixing it with the quartz sand for a more thorough cleaning.

[0009] As a further embodiment of the present invention, the heating assembly includes a U-shaped heating tube, which is an electric heating tube. The U-shaped heating tube is bent into an arc-shaped tube that fits snugly against the outer wall of the spiral pickling tank. Terminals are provided at both ends of the U-shaped heating tube, which are electrically connected to an external power supply. The U-shaped heating tube has a large heat exchange area with the spiral pickling tank, enabling it to quickly reach the set temperature and shortening the preheating time. Furthermore, the U-shaped heating tube uniformly heats the entire pickling tank, avoiding local overheating or overcooling, improving heating efficiency, reducing energy consumption, and being safe and economical. The U-shaped heating tube better promotes the pickling reaction, enhancing the purification effect of quartz sand and the quality of the final product.

[0010] As a further embodiment of the present invention, the pickling liquid outlet assembly includes a liquid outlet pipe, on which a filter and a liquid outlet valve are sequentially arranged along the outlet direction. The filter removes solid impurities generated during the pickling process, ensuring the cleanliness of the discharged pickling liquid, thereby improving the quality of subsequent processing or use. Furthermore, the risk of pipe blockage is reduced, and the liquid outlet valve precisely controls the outflow rate and flow rate of the pickling liquid, improving reliability and service life.

[0011] As a further solution of the present invention, the spiral pickling tank is equipped with a discharge cone, the upper diameter of which is larger than the lower diameter, and the lower diameter of which is directly opposite the collection opening of the supporting mesh tank. The discharge cone helps the quartz sand to fall smoothly and completely with little residue.

[0012] As a further feature of this invention, the bottom of the cleaning tank is symmetrically provided with two drain outlets, each circumferentially symmetrical. These outlets are equipped with drain pipes, each fitted with a drain valve, and connected to an external drainage collection system. These two drain outlets improve drainage efficiency, rapidly discharging wastewater generated during the cleaning process and reducing cleaning time. This prevents water accumulation within the cleaning tank and improves cleaning effectiveness.

[0013] As a further solution of the present invention, a discharge port is provided at the lower end of the carrier mesh trough, a discharge pipe is provided at the discharge port, a discharge valve is provided on the discharge pipe, and a collection device is received outside the discharge pipe. The discharge valve can be opened or closed according to the amount of material accumulated in the carrier mesh trough, providing flexible control and convenient discharge.

[0014] As a further embodiment of the present invention, the support mesh trough is a tapered trough with a gradually decreasing diameter from top to bottom. The feed opening of the support mesh trough is open, the bottom of the support mesh trough is sealed and fixed to the bottom plate of the cleaning tank, and the side walls of the support mesh trough are formed by a support mesh, the mesh diameter of which is smaller than the diameter of the quartz sand particles. The quartz sand is retained within the support mesh trough by the support mesh and does not leak into the space between the support mesh trough and the cleaning tank. The cleaning water freely enters the support mesh trough along the mesh holes, fully mixes with the quartz sand, and finally achieves physical separation of the quartz sand and clear water, which can effectively separate and dry the quartz sand.

[0015] As a further embodiment of the present invention, the spray assembly includes a horizontally disposed liquid outlet manifold, the end of which is sealed, and a plurality of liquid outlet nozzles disposed on the liquid outlet manifold, each of which is disposed at the upper opening of the carrier mesh trough. The liquid outlet nozzles disposed at the end of the liquid outlet manifold are tilted downward, away from one end of the liquid outlet pipe. The multiple liquid outlet nozzles are evenly distributed on the liquid outlet manifold, and the cleaning liquid is evenly sprayed on the quartz sand, thereby improving the cleaning effect. The downward tilt of the nozzles disposed at the end of the liquid outlet manifold helps the cleaning liquid more effectively cover the quartz sand particles in the carrier mesh trough, thereby promoting cleaning and infiltration of the material.

[0016] As a further solution of the present invention, the stirring assembly includes a stirring motor and a stirring shaft installed vertically downward, the stirring shaft extends into the cleaning box, the lower end of the stirring shaft is provided with a mounting bearing, the bottom of the mounting bearing is fixed to the bottom of the cleaning box, and a spiral blade is wound on the stirring shaft along the axial direction from top to bottom.

[0017] The vertical downward stirring shaft design combined with spiral blades continuously stirs the cleaning water to form a turbulent and agitated state, keeping it fully mixed with the quartz sand for washing, improving cleaning efficiency and shortening cleaning time.

[0018] As a further solution of the present invention, a first support frame is provided at the bottom of the spiral pickling tank, and the first support frame includes a first leg and a second leg. The first leg is arranged at the bottom of the tank body on the lower end side of the spiral pickling tank, and the second leg is arranged at the bottom of the tank body on the high end side of the spiral pickling tank. The lower ends of the first leg and the second leg are both fixed on the mounting surface;

[0019] The bottom of the cleaning box is provided with four supporting legs that are opposite and symmetrically arranged in pairs, and the lower end of each supporting leg is fixed on the installation surface.

[0021] The utility model provides a quartz sand pickling and purification device, which comprises an inclined spiral pickling tank, a pickling liquid storage tank is provided above the spiral pickling tank, a pickling pipe is arranged along the length direction of the spiral pickling tank, and high-pressure nozzles are uniformly distributed along the length direction of the pickling pipe; the high-pressure nozzles make the pickling liquid automatically supplied and distributed more evenly, and the pickling liquid contacts the quartz sand more fully.

[0022] The outer wall of the spiral pickling tank is equipped with several parallel heating components to maintain the optimal temperature of the pickling solution, promote chemical reactions, and increase purification speed. Quartz sand is quickly transferred from the feed to the discharge port, and pickling is carried out simultaneously, reducing acid waste. At the same time, unreacted acid is efficiently recovered through cleaning, reducing the risk of environmental pollution.

[0023] The cleaning mechanism comprises an upwardly open cleaning tank, which houses a mesh trough. The upper end of the trough houses a collection port, directly opposite the discharge port. A spray assembly is located above the collection port, and a stirring assembly is circumferentially located between the trough and the cleaning tank.

[0030] Example 1

[0031] like Figures 1 to 2As shown, a quartz sand pickling and purification device includes a spiral pickling tank 2 arranged at an angle, a first support frame 1 is provided at the bottom of the spiral pickling tank, and the first support frame includes a first leg and a second leg. The first leg is arranged at the bottom of the tank body on the lower end side of the spiral pickling tank, and the second leg is arranged at the bottom of the tank body on the high end side of the spiral pickling tank. The lower ends of the first leg and the second leg are fixed on the mounting surface; the bolt pickling tank is fixedly installed by the first support frame.

[0032] A pickling liquid storage tank 3 is located above the spiral pickling tank. A bracket is provided at the bottom of the pickling liquid storage tank, which is mounted on the spiral pickling tank. A liquid inlet is provided at the top of the pickling liquid storage tank. Prepared pickling liquid can be added through the inlet, or several materials can be added to the pickling liquid storage tank in appropriate proportions for mixing.

[0033] A pickling pipe 302 is provided at the bottom of the pickling liquid storage tank to guide the flow of the pickling liquid. The pickling pipe is arranged along the length of the spiral pickling tank, and high-pressure nozzles 301 are evenly distributed along the length of the pickling pipe. The pickling liquid in the pickling liquid storage tank enters and fills the pickling pipe, and the high-pressure nozzle is turned on and sprayed out along the high-pressure nozzle.

[0034] A feed port 202 for quartz sand is provided at the notch on the lower end of the spiral pickling tank. Quartz sand is added to the spiral pickling tank along the feed port, and the spiral pickling tank 2 is started. The spiral conveyor belt in the spiral pickling tank continuously transports the quartz sand from the lower end to the higher end. During the transportation process, the pickling liquid is continuously sprayed on the quartz sand at a high speed, fully contacts and reacts with the quartz sand. In the process of the quartz sand moving from the lower end to the higher end, the pickling liquid is continuously sprayed, and the quartz sand is continuously turned over, so that all the quartz sand can fully react with the pickling liquid.

[0035] A pickling liquid outlet is located at the bottom of the spiral pickling tank, on the lower side. This outlet houses a pickling liquid outlet assembly 201, which includes a discharge pipe 211, along which a filter 212 and a discharge valve 213 are located. When the pickling liquid reaches a certain level in the spiral pickling tank, the contact time between the pickling liquid and the quartz sand increases, until the pickling liquid splashes out of the tank. Upon opening the discharge valve 213, the pickling liquid passes through the filter 212, filtering the quartz sand. After separation from the pickling liquid, the pickling liquid is discharged through the discharge pipe.

[0036] Example 2

[0037] The outer wall of the spiral pickling tank is provided with several parallel heating components 4, and the heating components include a U-shaped heating tube, which is an electric heating tube. The U-shaped heating tube is bent into an arc tube that fits the outer wall of the spiral pickling tank. Terminals are provided at both ends of the U-shaped heating tube, and the terminal blocks are electrically connected to an external power supply.

[0038] During the entire pickling process, the U-shaped heating tube is turned on. When the optimal temperature is reached, the U-shaped heating tube stops heating. When the temperature drops, the U-shaped heating tube is turned on again, always maintaining the optimal reaction temperature and making the acidification reaction more thorough.

[0039] A discharge port 203 is located at the bottom of the spiral pickling tank on the upper side. This port is equipped with a discharge cone 231. The upper diameter of the discharge cone is larger than the lower diameter, and the lower end of the discharge cone is directly opposite the feed opening of the supporting mesh trough. Quartz sand is transported from the lower end of the spiral pickling tank to the top of the tank, pushed through the discharge port into the discharge cone, and then falls along the discharge cone into the supporting mesh trough.

[0040] Example 3

[0041] A cleaning mechanism is provided directly below the discharge port; the cleaning mechanism comprises an upwardly open cleaning box 505, the bottom of which is provided with four legs 6 arranged opposite and symmetrically in pairs, the lower end of each leg being fixed to the mounting surface. The cleaning box is fixed to the mounting surface by the four legs.

[0042] The cleaning box is equipped with a mesh trough 504, which is a tapered trough with a gradually decreasing diameter from top to bottom. The trough's collection opening is open, and the trough's bottom is sealed and fixed to the cleaning box's floor. The sidewalls of the trough are formed by a mesh with a mesh diameter smaller than that of the quartz sand particles. Quartz sand falls into the trough and accumulates until it reaches a certain volume.

[0043] The upper end of the supporting mesh trough is set as a collection port that is arranged opposite to the discharge port. A spraying component 501 is also provided above the collection port. The spraying component 501 includes a horizontally arranged liquid outlet main pipe 511, the end of the liquid outlet main pipe is closed, and three liquid outlet nozzles 512 are provided on the liquid outlet main pipe. Each liquid outlet nozzle is arranged at the upper mouth of the supporting mesh trough, and the liquid outlet nozzle arranged at the end of the liquid outlet main pipe is inclined downward away from one end of the liquid outlet pipe.

[0044] Open the liquid outlet nozzle 512, lead the external cleaning water along the liquid outlet main pipe, spray it through the liquid outlet nozzle 512, spray it on the surface of the quartz sand, and rinse the pickling liquid on the surface of the quartz sand. First rinse the upper layer of quartz sand, and then fall to the surface of the lower layer of quartz sand, layer by layer, continuously rinse until the water level of the cleaning water continues to rise and immerse the quartz sand. After that, the quartz sand is completely immersed in it and cleaned.

[0045] The bottom of the cleaning tank 505 is symmetrically provided with two drain outlets, each equipped with a drain pipe 503 and a drain valve 531. The drain pipe is connected to an external drainage collection system. If the concentration of the pickling solution in the cleaning water exceeds the specified concentration, the drain valve is opened, and the cleaning water is discharged through the drain pipe to the external drainage collection system. A new round of pure cleaning water is sprayed onto the quartz sand through the liquid outlet nozzle, repeatedly cleaning the quartz sand until the surface is completely clean. Finally, the cleaning water is discharged through the drain pipe to the external drainage collection system.

[0046] The lower end of the support mesh trough 504 is equipped with a discharge port, which is equipped with a discharge pipe 506. The discharge pipe is equipped with a discharge valve 561, and a collection device is connected to the discharge pipe. After the quartz sand is repeatedly washed with cleaning water and drained, the remaining moisture in the gaps between and on the surface of the quartz sand falls through the gaps due to gravity and is eventually separated by the mesh of the support mesh, thus completing the initial drying of the quartz sand. When the discharge valve is opened, the quartz sand is discharged through the discharge pipe and into the collection device for transfer to the next process.

[0047] Example 4

[0048] Based on the cleaning method of Example 3, a stirring assembly 502 is provided circumferentially between the supporting mesh tank and the cleaning box. The stirring assembly 502 includes a stirring motor 521 and a stirring shaft 522 installed vertically downward. The stirring shaft extends into the cleaning box, and a mounting bearing 524 is provided at the lower end of the stirring shaft. The bottom of the mounting bearing is fixed to the bottom of the cleaning box. A spiral blade 523 is wound axially from top to bottom on the stirring shaft.

[0049] During the entire cleaning process, the stirring motor 521 is turned on to drive the stirring shaft to rotate forward or reverse, driving the spiral blades to rotate, disturbing the cleaning water, creating turbulence and oscillation effects. This causes the cleaning water in contact with the quartz sand to vibrate and collide violently, causing the acid wash solution on the surface of the quartz sand to continuously dissolve into the water. Finally, the quartz sand is thoroughly cleaned.

[0050] After the quartz sand is repeatedly washed with cleaning water in the presence of agitators, the remaining water in the gaps between and on the surface of the sand falls by gravity as the cleaning water is drained. The water is eventually separated by the mesh of the support net, marking the initial drying of the sand. The discharge valve is opened, and the sand is discharged through the discharge pipe into a collection device for transfer to the next process.

[0051] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
