Description

Technical Field

[0001] This utility model belongs to the technical field of thickener equipment and relates to a feeding hopper for a hydrometallurgical pressure leaching reinforced concrete thickener. Background Technology

[0002] In nickel hydrometallurgy, solid-liquid separation of the reacted materials is often required. Thickeners, as important solid-liquid separation equipment, are used more frequently in nickel hydrometallurgy. Traditional concrete thickeners have a feed hopper that is cast as a single piece, fixed before the tank body is poured, and then cast as a whole with the concrete tank body. If the feed hopper is damaged during subsequent use, it cannot be replaced separately, and a new thickener must be built. This not only causes production system shutdown but also incurs high construction costs. Therefore, it is essential to develop a reinforced concrete thickener feed hopper that can be easily replaced separately. Utility Model Content

[0003] The purpose of this utility model is to address the problems existing in the prior art by providing a feeding hopper for a hydrometallurgical pressure leaching reinforced concrete thickener. This solves the problem that in traditional concrete thickeners, the feeding port is integrated with the concrete pool, making it impossible to replace the feeding hopper separately if it is damaged during subsequent use.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A hopper for a hydrometallurgical pressure leaching reinforced concrete thickener includes a hopper body. A pre-embedded steel plate, an upper connecting plate, and a lower connecting plate are sequentially arranged above the hopper body. The lower connecting plate and the upper connecting plate are connected by double-ended studs and double nuts. The hopper body and the lower connecting plate are fixedly connected. A second connecting pipe is provided on the side of the hopper body and a first connecting pipe is provided at the bottom. The hopper body and the second connecting pipe are vertically connected.

[0006] Furthermore, the upper connecting plate is provided with a plurality of plug welding holes arranged symmetrically, specifically, the plug welding holes are through holes; a first threaded hole is provided between adjacent plug welding holes, and the lower connecting plate is provided with a second threaded hole, the first threaded hole and the second threaded hole are connected by a double-ended stud.

[0007] Furthermore, a number of reinforcing ribs are provided at the connection between the hopper body and the lower connecting plate, with one end of the reinforcing ribs connected to the hopper body and the other end connected to the lower connecting plate.

[0008] Furthermore, the first connector is L-shaped.

[0009] Furthermore, the lower surface of the embedded steel plate is provided with a ring platform.

[0010] Furthermore, the upper connecting plate is provided with a tenon and the lower connecting plate is provided with a mortise, and the tenon and the mortise are connected by a sealing gasket; specifically, the sealing gasket is made of polytetrafluoroethylene.

[0011] The beneficial effects of this utility model are as follows:

[0012] In use, this utility model pre-embeds a steel plate at the bottom of the thickener, plugs and fillets welds the upper connecting plate to the pre-embedded steel plate, bolts the lower connecting plate to the upper connecting plate, and welds the lower connecting plate to the main body of the hopper. This makes the hopper quick and easy to install, and facilitates maintenance and replacement. It solves the problem of excessively long repair and replacement time when the hopper of the transmission thickener is damaged, and extends the overall service life of the thickener.

Detailed Implementation

[0018] The technical solution of this utility model will be described below with reference to the accompanying drawings and implementation methods.

[0019] like Figure 1 As shown, a hopper for a hydrometallurgical pressure leaching reinforced concrete thickener includes a hopper body 5. Specifically, the hopper body 5 is conical in shape, with the diameter decreasing from top to bottom. The hopper body 5 has a second connecting pipe 7 on its side and a first connecting pipe 6 at its bottom. The first connecting pipe 6 is L-shaped, and the hopper body 5 and the second connecting pipe 7 are vertically connected.

[0020] Above the main body 5 of the hopper, there is a pre-embedded steel plate 1, an upper connecting plate 2, and a lower connecting plate 3 arranged in sequence. The lower surface of the pre-embedded steel plate 1 has a ring platform 11, located on the side of the upper connecting plate 2, which serves a positioning function; Figure 2As shown, the lower connecting plate 3 and the upper connecting plate 2 are connected by double-headed studs 9 and double nuts 8, and the hopper body 5 is fixedly connected to the lower connecting plate 3.
