Description

Technical Field

[0001] This utility model relates to the field of chromium salt production technology, specifically to a chromium slag recovery device in chromium salt production. Background Technology

[0002] Chromium salts are one of the major series of inorganic chemical products in my country, and they have a wide range of applications. The main products of chromium salts include sodium dichromate and chromic anhydride, as well as small amounts of potassium dichromate, chromium oxide green, basic chromium sulfate and some chromium-containing pigments. Chromium slag is an industrial waste generated during the production of metallic chromium and chromium salts, which has certain hazards to humans and the environment.

[0003] Currently, when producing chromium salts, chromium slag recovery devices are often used. However, cleaning chromium slag usually requires disassembling the entire device, which is complicated and operators cannot clearly observe the progress of chromium slag recovery, thus reducing the practicality of the chromium slag recovery device.

[0004] For example, application number CN209530217U describes a chromium slag recovery device for chromium-containing wastewater. The device consists of a closed three-layer recovery box. However, if a forward or reverse motor or screw malfunctions, the entire device needs to be dismantled. Furthermore, operators cannot determine the progress of chromium slag recovery in real time, which affects the entire filtration and recovery process and reduces the practicality of the chromium slag recovery device. Utility Model Content

[0005] One object of this invention is to solve at least the aforementioned problems and / or defects, and to provide at least the advantages described below.

[0006] To achieve these objectives and other advantages according to this utility model, a chromium slag recovery device for chromium salt production is provided, comprising: a recovery box, wherein a conveying pipe and a discharge pipe are respectively connected through the top and bottom of its side wall, the recovery box being fixed on a box base, and further comprising:

[0007] A filter box with a fixing plate at its top is detachably connected to the recycling bin.

[0008] A fixed frame, one end of which is provided with a movable plate, and the other end of the fixed frame is detachably connected to the fixed plate;

[0009] A limiting plate is hinged to an adjusting component, the other end of which is hinged to the moving plate. The limiting plate is fixedly installed on the side of the recycling bin.

[0021] In this device, the vibration generated by the vibrating motor can vibrate and screen the chromium slag on the filter box inside the recycling bin. When it is necessary to recycle the chromium slag in the filter box, the operator can adjust the components to move the filter box out of the recycling bin by the moving plate.

[0032] The following is a detailed description of this novel experimental device with reference to the accompanying drawings:

[0033] Figure 1-4 This invention discloses a chromium slag recovery device in chromium salt production, comprising: a recovery box 1, wherein a conveying pipe 11 and a discharge pipe 12 are respectively connected to the top and bottom of its side wall; the recovery box 1 is fixed on a box base 2; and further comprising:

[0034] The filter box 3 has a fixing plate 31 at its top, and the filter box 3 is detachably connected to the recycling bin 1;

[0035] A fixed frame 4 has a movable plate 41 at one end, and the other end of the fixed frame 4 is detachably connected to the fixed plate 31.

[0036] A limiting plate 5 is hinged to an adjusting component 6, the other end of which is hinged to the moving plate 41. The limiting plate 5 is fixedly installed on the side of the recycling bin 1.

[0037] The vibration assembly 7 is equipped with a vibration motor 71, which is mounted on the bottom of the housing 2.

[0038] Working principle:

[0039] The chromium slag waste liquid is transported to the filter box 3 in the recycling box 1 through the conveying pipe 11. At this time, the vibration component 7 on the box base 2 starts to work. The vibration motor 71 is started by the external power supply. The vibration generated by the vibration motor 71 vibrates and screens the chromium slag waste liquid in the filter box 3. The chromium slag is left in the filter box 3, and the filtered chromium slag waste liquid leaves from the discharge pipe 12.

[0040] During the recycling process, the operator observes the chromium slag in the filter box 3. When recycling is required, the conveying operation of the conveying pipe 11 is stopped. Since the limiting plate 5 is fixed to the side of the recycling box 1, the hinged adjustment component 6 drives the moving plate 41 to move vertically. At this time, the fixing frame 4, which is fixed to the moving plate 41, moves the filter box 3 vertically out of the recycling box 1 through the fixing plate 31 at the other end of the fixing frame 4.

[0041] At this point, the chromium slag can be easily cleaned without disassembling the entire device. This method is simple to operate and allows for clear observation of the progress of chromium slag recovery, thus improving the practicality of the chromium slag recovery device.

[0042] The detachable connection between the fixing plate 31 and the fixing frame 4 allows for various convenient disassembly methods, such as clips and bolts, to be selected according to operational needs during actual use.

[0043] As described above, the inner wall of the recycling bin 1 is symmetrically provided with positioning grooves 13, and the bottom of the filter box 3 is symmetrically provided with positioning plates 32, with the positioning grooves 12 and the positioning plates 32 being embedded and connected.

[0044] Working principle:

[0045] The filter box 3 is detachably connected to the recycling bin 1 in the following manner:

[0046] The bottom of the filter box 3 is symmetrically provided with positioning plates 32, which are matched in shape and size with the positioning grooves 13 symmetrically provided on the inner wall of the recycling box 1 to form an embedded snap-fit ​​connection, thereby achieving the limit. The structure is simple and makes it convenient for operators to operate.

[0047] As described above, the structure of adjustment component 6 includes:

[0048] A drive motor 61 is mounted on the limiting plate 5;

[0049] The screw 62 has threads on its surface and is fixed to the rotating shaft of the drive motor 61;

[0050] A threaded sleeve 63 has internal threads and is installed at the bottom of the movable plate 41; the screw 62 is threadedly connected to the threaded sleeve 63.

[0051] The folding rod 64 has one end hinged to the moving plate 41 and the other end hinged to the limiting plate 5. Two sets of the folding rod 64 are symmetrically arranged about the screw 62.

[0052] Working principle:

[0053] The specific method by which the adjusting component 6 drives the moving plate 41 to move vertically is as follows:

[0054] The drive motor 61 on the limit plate 5 is started by an external power supply, so that the drive motor 61 drives the screw 62 to rotate in the threaded sleeve 63, so that the thread on the surface of the screw 62 slides along the thread in the threaded sleeve 63. The folding rods 64 hinged on both sides of the moving plate 41 provide support, and the threaded sleeve 63 drives the moving plate 41 to move vertically.

[0055] This structure is simple and easy to operate, improving the convenience of cleaning chromium slag inside filter box 3.

[0056] As described above, the structure of the vibration component 7 includes:

[0057] Vibration motor 71 is installed at the bottom of the housing 2;

[0058] A rubber damper 72, with a spring 73 sleeved on its outer ring, is installed between the vibration damping seat 74 and the housing 2.

[0059] Working principle:

[0060] During the recycling process, the vibration motor 71 is started by an external power source, which causes the base 2 to drive the recycling box 1 to vibrate. At this time, a spring 73 and a rubber damper 72 are installed between the shock absorber 74 and the base 2, which can provide support for the stable vibration of the recycling box 1, and at the same time effectively absorb vibration energy and reduce vibration amplitude and noise.

[0061] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
