Description

Technical Field

[0001] This utility model relates to the field of quartz sand pickling technology, specifically to a quartz sand pickling device. Background Technology

[0002] Natural quartz sand often has an iron film adhering to its surface. Acid washing can remove impurities such as iron oxide and ferric iron, avoiding the impact on iron-sensitive industries such as glass manufacturing. At the same time, acid washing can dissolve mineral impurities such as mica, aluminum, potassium, and manganese. In order to facilitate the reaction of quartz sand in the acid washing tank with the acid washing solution and the removal of the quartz sand, this utility model proposes an acid washing device for quartz sand. Summary of the Invention

[0003] The purpose of this invention is to provide an acid washing device for quartz sand to solve the problems mentioned in the background art.

[0005] Preferably, the pickling tank is equipped with a first motor and a second motor, which are used to drive the first screw and the second screw to rotate, respectively.

[0006] Preferably, the bottom of the pickling tank is semi-circular and slidably connected to the spiral blades on the first spiral rod.

[0007] Preferably, filter screens are provided between the pickling tanks and between the inner walls of the pickling tanks and the pickling pools.

[0008] Preferably, the pickling tank is provided with an inlet that communicates with the pickling tank, and the top of the discharge tank is provided with an inclined discharge outlet.

[0009] Compared with the prior art, the beneficial effects of this utility model are: by pouring quartz sand into the pickling tank from the feed port and moving along the pickling tank under the rotation of the first screw, the acid solution is pumped into the pickling tank from the acid injection pipe and overflows from the top of the pickling tank, and falls into the pickling pool after being filtered by the filter screen.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Referring to Figures (1-3), an acid washing device for quartz sand includes an acid washing tank 1, which contains several acid washing troughs 12. A first spiral rod 2 is rotatably installed in each acid washing trough 12. A discharge trough 13 is installed at one end of each acid washing trough 12. A second spiral rod 6 is rotatably installed in the discharge trough 13. An acid injection pipe 3 is installed below the acid washing trough 12. Several branch pipes 31 are connected to the acid injection pipe 3. One end of each branch pipe 31 is connected to the bottom of the acid washing trough 12. A circulation pipe 5 is connected to the bottom of the acid washing tank 1.

[0016] The pickling tank 1 is equipped with a first motor 21 and a second motor 61, which drive the first spiral rod 2 and the second spiral rod 6 to rotate, respectively. The bottom of the pickling tank 12 is semi-circular and slidably connected to the spiral blades on the first spiral rod 2. Filter screens 4 are provided between the pickling tanks 12 and between the pickling tank 12 and the inner wall of the pickling tank 1. The pickling tank 1 is provided with an inlet 11 communicating with the pickling tank 12, and the top of the discharge trough 13 is provided with an inclined discharge port 14.

[0017] In use, the device pours quartz sand into the pickling tank 12 through the feed inlet 11. The first motor 21 is started to drive the first screw rod 2 to rotate, causing the spiral blades on the first screw rod 2 to rotate and push the quartz sand in the pickling tank 12 to move. At the same time, an acidic solution is pumped into the pickling tank 12 through a liquid pump to mix with the quartz sand in the pickling tank 12 and dissolve the impurities. Then the acidic solution overflows from the pickling tank and falls into the pickling pool 1 after being filtered through a filter screen. The reacted solution that falls into the pickling pool can be extracted through a circulation pipe by the liquid pump. The quartz sand in the pickling tank is pushed into the discharge trough 13 by the first screw rod 2. The second screw rod 6 rotates and drives the quartz sand in the discharge trough 13 to move upward and slide out from the discharge port 14.

[0018] The orientations or positional relationships shown in the accompanying drawings are for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.
