Description

Technical Field

[0001] The utility model relates to a crystal recovery device, and more specifically, particularly to a copper sulfate crystal recovery device. Background Art

[0002] Copper sulfate crystals refer to the removal of copper ions from a copper sulfate solution by crystal growth. The physical cooling method of copper sulfate crystals is an environmentally friendly and efficient method for removing copper ions. It uses copper ions Cu2+ and sulfate ions SO42- in a sulfuric acid and hydrogen peroxide micro-etching solution to form copper sulfate crystals under saturated conditions for separation and recovery, and then physically cools the solution through an ice water pipe to condense and precipitate.

[0003] In the existing recycling process, after the precipitation and crystallization are completed, the copper sulfate pentahydrate crystals are output to the collection tank through a screw conveyor for collection and filtering of the small amount of liquid carried, and then the crystals in the collection tank are recycled. In the existing process, when recycling the crystals in the collection tank, the crystals are usually scooped up manually with a shovel for bagging or transportation. This kind of manual shoveling can only be done from top to bottom, so the screw conveyor cannot continuously transport the crystals to the collection tank during shoveling, and the recycling efficiency is low. At the same time, in order to facilitate shoveling, the collection tank can only be set to an open type, and the small amount of toxic gas present will be emitted into the working environment, affecting the health of the workers.

DETAILED DESCRIPTION

[0020] See also Figure 1-5 As shown, a copper sulfate crystal recovery device of the utility model comprises a box body 1, a box cover 2 is provided on the box body 1, a feed pipe 3 connected to an external crystallization device and connected to the box cover 2 is provided above the box body 1; two filter screens 4 for filtering out moisture are symmetrically and tilted in the middle of the box body 1, and a spiral discharge assembly 5 is provided between the tilted lower ends of the two filter screens 4; an umbrella-shaped guide plate 6 matched with the two filter screens 4 is provided at the proximal end of the opening end of the box body 1 below the feed pipe 3; a liquid extraction pipe 7 for recovering liquid is provided at the bottom of the box body 1. The moisture of the copper sulfate crystals is filtered out by the filter screen and then guided to the spiral conveying assembly for timed or quantitative output. The spiral conveying assembly is located at the bottom, and the feed pipe above can continue to convey the feed when discharging, effectively improving the crystal recovery efficiency and reducing the labor of workers. In addition, the box cover can reduce the emission of toxic gases into the surrounding environment, reduce environmental pollution, and protect the health of workers.

[0021] The inclination angle between the filter screen and the horizontal plane is 15-25°, so that the copper sulfate crystals can stay for a sufficient time to fully drain the carried liquid while sliding down the filter screen.

[0022] The spiral conveying assembly includes a motor, spiral blades, etc., and its specific structure and connection method are all existing technologies and will not be repeated here.

[0023] In this embodiment, the box cover 2 includes a mounting frame 2a matched with the open end of the box body 1, a mounting ring 2b is provided on the feed pipe 3, and a cover body 2c made of a flexible corrosion-resistant material is connected between the mounting frame 2a and the mounting ring 2b.

[0024] Two first hanging rings 2d are symmetrically arranged on the installation frame 2a, and a bracket 2e connected to the side wall of the material conveying pipe 3 is arranged above each first hanging ring 2d, and a hook 2f matching with the first hanging ring 2d is arranged at the bottom of the bracket 2e. When it is necessary to clean the inside of the box, the installation frame is lifted and the first hanging ring is hung on the hook.

[0025] Preferably, the box 1 includes a lower box 1a for collecting liquid, and the liquid extraction pipe 7 is arranged in the lower box 1a; an upper box 1b with upper and lower openings is arranged on the lower box 1a, and the filter screen 4 and the spiral discharge assembly 5 are arranged at the lower end near the upper box 1b; a limit ring 1c matching the inner wall of the lower box 1a is arranged at the lower open end of the upper box 1b. With this structure, it is convenient to disassemble and clean the lower box, and the connection between the upper end of the limit ring and the inner side of the upper box is set as a connection angle inclined downward to prevent the filtered copper sulfate solution from accumulating at the upper end of the limit ring, and to prevent the precipitation and crystallization after long-term accumulation of liquid from being difficult to clean and causing waste.

[0026] In this embodiment, the filter screen 4 includes a frame 4a, on which a mesh frame 4b with a surface covered with filter paper is provided; a second hanging ring 4c is provided at the upper end of the frame 4a, and a plurality of stoppers 4d are provided at the bottom of the lower end of the frame 4a. Since the copper sulfate crystals are in powder form and have a small volume, they need to pass through a filter membrane or filter paper. At the same time, since the copper sulfate crystals do not carry much water, they need to stay for a period of time to filter out the water. Using filter paper with a large surface friction can slow down the speed of the copper sulfate crystals sliding down, so that the water can be filtered out as much as possible.

[0027] Support blocks 4e are provided on the inner walls of both sides of the box 1, and baffles 4f are provided on both sides of the spiral discharging assembly 5; when the filter 4 is placed in the box 1, the upper end of the frame 4a is placed on the support block 4e, and the baffle 4d is close to the outer side of the baffle 4f. With this structure, it is convenient to disassemble the filter for cleaning or replacement. When installing, first hook the second lifting ring with a lifting device to lift the filter, and then slowly lower the upper end of the frame onto the support block after the bottom of the lower end of the frame contacts the baffle to complete the installation.

[0028] In this embodiment, preferably, the umbrella-shaped guide plate 6 includes a mounting rod 6a with a T-shaped vertical cross section, and guide plates 6b inclined toward both sides are symmetrically arranged on the mounting rod 6a; a mounting beam 6c parallel to the spiral discharging assembly 5 is arranged at the proximal end of the opening end of the box body 1, and a mounting groove 6d matching the mounting rod 6a is arranged on the mounting beam 6c; and a third hanging ring 6e is arranged at both ends of the guide plate 6b along the length direction. With this structure, it is convenient to disassemble and assemble the umbrella-shaped guide plate, and avoid interference caused by the umbrella-shaped guide plate when disassembling and assembling the filter screen or cleaning the inside of the box body. At the same time, the bottom of the mounting rod and the mounting groove can be set to a hemispherical shape, so that the bottom of the mounting rod can smoothly enter the mounting groove during installation.

[0029] During operation, the copper sulfate crystals generated in the precipitation crystallization equipment are transported into the upper box through the feed pipe, filtered on the mesh filter paper on both sides of the guide plate and gradually fall downward into the spiral discharging component. When the copper sulfate crystals in the first box reach a certain amount, the spiral discharging component starts to discharge.

[0030] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
