Description

Technical Field

[0001] This utility model relates to the field of reaction vessels, and in particular to a quartz sand pickling reaction vessel. Background Technology

[0002] Quartz sand is a mineral raw material widely used in the glass, ceramics, photovoltaic and electronics industries. Its main component is silicon dioxide. Natural quartz sand usually contains impurities such as iron, aluminum and titanium. Therefore, during the processing of quartz sand, it needs to be acid washed to remove impurities and improve the purity of the product.

[0003] In existing technologies, during the acid washing process of quartz sand, the acid washing solution is often injected into the tank from a single inlet, resulting in a high concentration of the acid washing solution in a local area of ​​the tank and a slow diffusion rate, which affects the acid washing effect of the quartz sand. In addition, during the agitation and acid washing process of quartz sand in traditional acid washing tanks, quartz sand particles tend to settle at the bottom of the tank, resulting in insufficient contact between the acid and the quartz sand, which affects the acid washing efficiency of the quartz sand.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a quartz sand pickling reaction vessel with good pickling effect and effective improvement of pickling efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution: a quartz sand pickling reaction tank, comprising a pickling tank body, a feeding mechanism, a swirling stirring mechanism, an acid delivery pipe, and a discharge valve;

[0007] The pickling tank has an internal accommodating chamber, and the feeding mechanism is connected to the pickling tank to transport the quartz sand to be pickled into the accommodating chamber.

[0008] The acid delivery pipe includes an annular pipe, an inlet pipe, and an outlet pipe. The annular pipe is located at the bottom of the accommodating chamber. The inlet pipe passes through the pickling tank and communicates with the annular pipe. Several outlet pipes are equidistantly arranged along the circumference of the annular pipe. The outlet pipes are used to deliver the pickling solution into the accommodating chamber.

[0009] The swirling stirring mechanism is located within the accommodating chamber. It is used to stir the quartz sand. The swirling stirring mechanism includes a drive motor, a rotating shaft, a swirling cone, and stirring blades. The drive motor is located at the top of the pickling tank, with its output shaft facing downwards and connected to the rotating shaft. The swirling cone is mounted on the rotating shaft and is used to guide the pickling solution and quartz sand to form a swirling flow within the pickling tank. The stirring blades are located at the bottom of the rotating shaft and are used to stir the quartz sand at the bottom of the pickling tank.

[0010] The discharge valve is located at the bottom of the pickling tank for discharging the quartz sand inside the pickling tank.

[0011] Using the above technical solution, in the quartz sand pickling reaction tank, the cross-sectional area of ​​the swirling cone disk gradually increases from top to bottom, and the swirling cone disk is provided with multiple equidistant arc-shaped baffles along the circumferential direction, the cross-section of the arc-shaped baffles having a triangular structure.

[0012] Using the above technical solution, in the quartz sand pickling reaction tank, the feeding mechanism includes a storage hopper and a screw conveyor. The storage hopper is used to store quartz sand, and the screw conveyor is connected to the bottom of the storage hopper to transport the quartz sand into the pickling tank.

[0013] Using the above technical solution, in the quartz sand pickling reaction tank, the top of the pickling tank body has a feed inlet, which is used to receive quartz sand conveyed from the screw conveyor.

[0014] The feed inlet is equipped with a baffle adjustment mechanism, which is used to adjust the opening size of the feed inlet. The baffle adjustment mechanism includes a push cylinder, a baffle plate, a fixed frame, and pulleys. Multiple pulleys are respectively arranged on both sides of the fixed frame. The baffle plate can slide along the pulleys. The movable end of the push cylinder is connected to the baffle plate. The push cylinder is used to push the baffle plate to move back and forth, so that the baffle plate blocks or opens the feed inlet.

[0015] The above technical solution includes a water inlet pipe and a liquid extraction pipe in the quartz sand pickling reaction tank, wherein the water inlet pipe and the liquid extraction pipe are respectively connected to the pickling tank body.

[0016] The inlet pipe is used to deliver cleaning water into the accommodating chamber, and the extraction pipe is used to extract the pickling solution from the accommodating chamber.

[0017] Using the above technical solution, the quartz sand pickling reaction tank is equipped with a filter screen inside the liquid extraction pipe for blocking quartz sand.

[0018] In the above technical solution, the quartz sand pickling reaction tank is further provided with a guide chute at the feed inlet, which is used to guide and transport the quartz sand to the feed inlet.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention places the annular acid delivery pipe at the bottom of the receiving chamber and arranges multiple outlet pipes at equal intervals along the circumference, allowing the pickling solution to be injected into the receiving chamber from multiple points, avoiding the phenomenon of excessively high or low local concentrations caused by injecting the acid solution from a single inlet. The swirling conical disc of the swirling stirring mechanism guides the pickling solution and quartz sand to form a swirling flow, ensuring that the quartz sand is fully agitated within the pickling tank, preventing particle accumulation and thus improving the pickling effect. Furthermore, the cross-sectional area of ​​the swirling conical disc gradually increases from top to bottom, allowing the pickling liquid and quartz sand particles to be gradually guided outwards, creating a stronger centrifugal effect and promoting thorough mixing of the quartz sand particles and the pickling solution within the receiving chamber. The stirring blades can stir the quartz sand at the bottom of the pickling tank and push the quartz sand particles upwards, preventing uneven pickling. Attached Figure Description

Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 4 As shown, this utility model embodiment provides a quartz sand pickling reaction tank, including a pickling tank body 1, a feeding mechanism 2, a swirling stirring mechanism 3, an acid delivery pipe 4, and a discharge valve 5;

[0031] The pickling tank 1 has an internal accommodating chamber. The feeding mechanism 2 is connected to the pickling tank 1 to transport the quartz sand to be pickled into the accommodating chamber. The acid delivery pipe 4 includes an annular pipe 41, an inlet pipe 42, and an outlet pipe 43. The annular pipe 41 is located at the bottom of the accommodating chamber. The inlet pipe 42 passes through the pickling tank 1 and is connected to the annular pipe 41. Several outlet pipes 43 are equidistantly arranged along the circumference of the annular pipe 41. The outlet pipes 43 are used to transport the pickling solution into the accommodating chamber. By placing the annular pipe 41 at the bottom of the accommodating chamber and equidistantly arranging multiple outlet pipes 43 along the circumference, the pickling solution can be injected into the accommodating chamber from multiple points, thereby ensuring that the pickling solution is evenly distributed in the pickling tank 1 and avoiding the situation where the local concentration is too high or too low due to the acid solution being injected from a single inlet.

[0032] The swirling stirring mechanism 3 is partially located within the accommodating cavity. The swirling stirring mechanism 3 is used to stir the quartz sand. The swirling stirring mechanism 3 includes a drive motor 31, a rotating shaft 32, a swirling conical disk 33, and stirring blades 34. The drive motor 31 is located at the top of the pickling tank 1, with its output shaft facing downwards and connected to the rotating shaft 32. The swirling conical disk 33 is mounted on the rotating shaft 32 and is used to guide the pickling solution and quartz sand to form a swirling flow in the pickling tank 1. The stirring blades 34 are located at the bottom of the rotating shaft 32. The stirring blades 34 are used to stir the quartz sand at the bottom of the pickling tank 1. When the drive motor 31 drives the rotating shaft 32 to rotate, it can simultaneously drive the swirling cone 33 and the stirring blades 34 to rotate. The swirling cone 33 can guide the pickling solution and quartz sand to form a swirling flow, so that the quartz sand is fully turned over in the pickling tank 1, avoiding particle accumulation and thus improving the pickling effect. The stirring blades 34 can stir the quartz sand at the bottom of the pickling tank 1 and push the quartz sand particles upward to avoid uneven pickling. The discharge valve 5 is located at the bottom of the pickling tank 1. After pickling is completed, the discharge valve 5 can be opened to discharge the quartz sand in the pickling tank 1.

[0033] like Figure 3 As shown, the cross-sectional area of ​​the vortex cone 33 gradually increases from top to bottom. The vortex cone 33 is provided with multiple equidistant arc-shaped baffles 331 along its circumference, and the cross-section of each arc-shaped baffle 331 is triangular. The gradual increase in cross-sectional area of ​​the vortex cone 33 from top to bottom allows the pickling liquid and quartz sand particles to be gradually guided outwards, creating a stronger centrifugal effect. This promotes thorough mixing of the quartz sand particles and the pickling solution within the containment chamber, improving the stirring and dispersion effect of the quartz sand particles. The triangular cross-section of the arc-shaped baffles 331 effectively reduces fluid resistance.

[0034] like Figure 1 As shown, the feeding mechanism 2 further includes a storage hopper 21 and a screw conveyor 22. The storage hopper 21 is used to store quartz sand, and the screw conveyor 22 is connected to the bottom of the storage hopper 21 to transport the quartz sand into the pickling tank 1. The storage hopper 21 provides sufficient material reserves for storing quartz sand, and the screw conveyor 22 can continuously transport quartz sand from the bottom of the storage hopper 21 into the pickling tank 1, realizing automatic feeding and effectively improving the pickling efficiency of quartz sand.

[0035] like Figure 2As shown, the pickling tank 1 further includes a feed inlet 10 at its top, which receives quartz sand conveyed from the screw conveyor 22. The feed inlet 10 is equipped with a baffle adjustment mechanism 6, which adjusts the opening of the feed inlet 10. The baffle adjustment mechanism 6 includes a push cylinder 61, a baffle plate 62, a fixing frame 63, and pulleys 64. Multiple pulleys 64 are respectively located on both sides of the fixing frame 63. The baffle plate 62 can slide along the pulleys 64. The movable end of the push cylinder 61 is connected to the baffle plate 62, and the push cylinder 61 pushes the baffle plate 62 to reciprocate, thus blocking or opening the feed inlet 10. The connection between the push cylinder 61 and the baffle plate 62 allows the baffle plate 62 to move automatically back and forth, thereby achieving automatic opening and closing control of the feed inlet 10, allowing the user to flexibly adjust the feed flow rate of the quartz sand according to actual conditions.

[0036] like Figure 1 and Figure 2 As shown, further, it also includes a water inlet pipe 71 and a liquid extraction pipe 72. The water inlet pipe 71 and the liquid extraction pipe 72 are respectively connected to the pickling tank 1. The water inlet pipe 71 is used to transport cleaning water to the receiving chamber. The liquid extraction pipe 72 can be connected to an external water pump to extract the pickling solution from the receiving chamber. The pickling solution is usually corrosive. After pickling is completed, the pickling solution in the pickling tank 1 can be discharged through the liquid extraction pipe 72. The water inlet pipe 71 can facilitate the delivery of cleaning water to the receiving chamber to clean the inner wall of the pickling tank 1 and flush away residual pickling solution and impurities.

[0037] Furthermore, the extraction pipe 72 is equipped with a filter screen (not shown) for blocking quartz sand. Quartz sand particles are relatively large and can easily enter the extraction pipe 72 during the extraction process, causing blockage. The filter screen can effectively block quartz sand particles and prevent quartz sand from flowing into the extraction pipe 72.

[0038] like Figure 2 As shown, the feed inlet 10 is further provided with a guide trough 101, which is used to guide and convey the quartz sand to the feed inlet 10. The guide trough 101 can prevent the quartz sand from overflowing during the feeding process, thereby improving the feeding stability of the quartz sand.

[0039] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
