Description

Technical Field

[0001] This utility model belongs to the field of non-ferrous metallurgical technology, specifically, it relates to a zinc liquid cylinder with buffer feeding. Background Technology

[0002] The zinc bath is the main storage equipment in the hydrometallurgical zinc smelting process, used to store zinc sulfate. Zinc sulfate solution is typically obtained by leaching and purifying zinc calcined sand. After storage in the zinc bath, the zinc sulfate solution needs to be sent to the zinc electrowinning process. The zinc bath serves as a transfer tank for the zinc sulfate solution, requiring continuous feeding (adding new zinc sulfate solution) and continuous discharging (sending the zinc sulfate solution from the zinc bath to the next process). Due to the presence of many impurities in the zinc sulfate solution, a slag layer with a thickness greater than 10 cm usually accumulates in the zinc bath during storage. Therefore, the zinc bath also serves as a sedimentation and impurity removal device. However, during the transfer of the zinc sulfate solution to the zinc bath, the feeding inevitably impacts the slag layer, causing it to enter the upper layer of the zinc sulfate solution. This results in an excessively high solids content in the zinc sulfate solution sent to the zinc electrowinning process, leading to impurities entering the production system, increasing the impurity level, affecting electrolytic efficiency, and potentially even causing plate burning and remelting. Summary of the Invention

[0003] In order to overcome the problems existing in the background technology, the present invention provides a zinc liquid tank with buffer feeding, which can effectively reduce or avoid the impact on the slag layer in the zinc liquid tank when the zinc sulfate solution is fed, reduce the impurity content of the zinc sulfate sent to the electrowinning process, and avoid the impact of solid phase entering the electrowinning process on production.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] The zinc liquid cylinder with buffered feeding includes a cylinder body and a buffer chamber located on the inner side of the bottom of the cylinder body; the buffer chamber is formed by two side plates, a door plate and a top plate; the two side plates are parallel and opposite to each other, with their inner sides connected to the inner wall of the cylinder body and their bottoms connected to the bottom of the cylinder body; the door plate is connected to the outer sides of the two side plates respectively; the top plate is located above the side plates and the door plate, and a guide hole is left between the top plate and the door plate; the outlet of the liquid inlet pipe of the cylinder body is directly opposite the buffer chamber.

[0006] Preferably, the upper inner side of the two side plates is provided with a slot, and the top plate is detachably connected to the two side plates through the slot.

[0007] Preferably, the side panels, door panels, and top panels are all made of acid-resistant ceramic tiles.

[0008] Preferably, the guide hole is higher than the slag layer inside the zinc liquid cylinder.

[0009] Preferably, the liquid outlet of the cylinder is located at the top of the cylinder.

[0010] The beneficial effects of this utility model are:

[0011] This invention provides a buffer chamber at the bottom inner side of the zinc bath cylinder. When the zinc sulfate solution is fed in, the impact of the feed on the slag layer inside the zinc bath cylinder can be effectively reduced or avoided. This prevents the precipitated slag from being mixed into the upper zinc sulfate solution due to the impact, thereby reducing the impurity content of the zinc sulfate sent to the electrowinning process and avoiding or reducing the impact of solids entering the electrowinning process on production.

[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0016] In the description of this utility model, unless otherwise stated, the terms "upper" and "lower" indicate the orientation or state relationship based on the orientation or state relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element 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 this utility model.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0018] like Figure 1 and 2 As shown, the zinc liquid cylinder with buffer feeding includes a zinc liquid cylinder body (cylinder body 7) and a buffer cavity disposed on the inner side of the bottom of the cylinder body 7.

[0019] The buffer chamber is formed by two side plates 2, a door plate 8, and a top plate 3. The two side plates 2 are parallel and opposite to each other. The inner side of the side plate 2 is connected to the inner wall of the cylinder body 7, and the bottom is connected to the bottom of the cylinder body 7. The door plate 8 is connected to the outer side of the two side plates 2 respectively. The side plates 2, door plates 8 and cylinder body 1 form a square cavity. The inner side of the top of the two side plates 2 is provided with slots 5 facing each other. The top plate 3 is detachably connected to the two side plates 2 through the slots 5. A gap is reserved between the door plate 8 and the top plate 3 to form a guide hole 4.

[0020] The outlet of the liquid inlet pipe 6 of the cylinder body 7 is directly opposite to or inserted into the buffer chamber. The zinc sulfate solution delivered by the liquid inlet pipe 6 first enters the buffer chamber, and then enters the zinc liquid cylinder 1 through the guide hole 4. The liquid inlet effectively avoids the slag layer in the zinc liquid cylinder 1, avoiding or reducing the impact of the liquid inlet on the slag layer at the bottom of the cylinder, thereby avoiding the increase of impurities in the zinc sulfate solution input to the next process due to the impact on the slag layer. During the design, the height of the side plate 2 and the door plate 8 is designed according to the normal thickness of the slag layer in the zinc liquid cylinder 1 to ensure that the position of the guide hole 4 is higher than the slag layer.

[0021] The top plate 3 is designed as a detachable structure because, although the buffer chamber of this invention can prevent the liquid from impacting the slag layer, the physical properties of zinc sulfate solution will cause crystals to appear in the buffer chamber after long-term use. The detachability of the top plate 3 makes it easier to clean the buffer chamber during maintenance of the zinc liquid tank 1.

[0022] The side panel 2, door panel 8, and top panel 3 are all made of acid-resistant ceramic tiles. As an application example of this utility model, the ceramic tile thickness is 50cm and the side panel height is 150cm. The guide hole 4 is a square hole with a size of 40cm×40cm.

[0023] As a standard practice, the liquid outlet of cylinder 7 is located at the top of cylinder 7.

[0024] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
