Description

Technical Field

[0001] This utility model relates to the field of sodium thiocyanate production technology, and in particular to an impurity filtration device for sodium thiocyanate production. Background Technology

[0002] Sodium thiocyanate, as an important chemical raw material, is widely used in industries such as textiles, pharmaceuticals, and pesticides. During its production process, due to factors such as raw material reactions and process conditions, the product solution often contains various solid impurities and suspended matter, requiring purification treatment through filtration devices.

[0003] However, existing sodium thiocyanate filtration devices still have some problems during use: most devices use fixed or bolted connections for their filter components, making disassembly and cleaning cumbersome and time-consuming, affecting production continuity; at the same time, the connection between the filter tube and the feed tube is prone to poor sealing or inaccurate positioning, which not only reduces filtration efficiency but may also cause equipment blockage due to impurity accumulation, increasing maintenance costs and energy consumption. Therefore, there is an urgent need for a filtration device that is easy to disassemble and clean and has a stable connection to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an impurity filtration device for sodium thiocyanate production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A filter device for impurities in sodium thiocyanate production includes a base, a tank on top of the base and supported by a support mechanism, a stirrer rotatably connected to the top of the tank, a rotating plate fixedly connected to the bottom of the stirrer, a motor for driving the stirrer to rotate fixedly connected to the top of the tank, a feed pipe communicating with the tank's interior fixedly connected to the bottom of the tank, a filter pipe sleeved on the bottom of the feed pipe and fixed by two fixing mechanisms, and a filter screen fixedly connected to the bottom of the filter pipe.

[0006] As a further improvement of this utility model, the support mechanism includes a support ring fixedly sleeved on the tank body, and support columns are fixedly connected to both sides of the bottom of the support ring, with the bottoms of the two support columns fixedly connected to the top of the base.

[0007] As a further improvement of this utility model, the same auxiliary support arc plate is fixedly connected to the same side of the two support columns.

[0008] As a further improvement of this utility model, the fixing mechanism includes an arc-shaped block fixedly connected to one side of the feed pipe. A connecting groove is provided at the top of the filter pipe, and the lower end of the arc-shaped block is inserted into the connecting groove. A plug-in groove is provided on one side of the lower end of the arc-shaped block. A support frame is fixedly connected to the outer wall of the filter pipe. A plug-in block is slidably connected to the support frame through a spring. A connecting column that is sleeved with the spring is fixedly connected to one side of the plug-in block. The other end of the connecting column passes through the support frame and is fixedly connected to a pull plate.

[0009] As a further improvement of this utility model, the connecting groove matches the size of the lower end of the arc-shaped block.

[0010] As a further improvement of this utility model, the top of the tank is fixedly connected to an inlet pipe communicating with its interior, the bottom of the filter pipe is fixedly connected to a valve communicating with its interior, and the bottom of the valve is fixedly connected to an outlet pipe communicating with its interior.

[0011] The beneficial effects of this utility model are: By incorporating a detachable connection structure between the feed pipe and the filter pipe, the filter pipe can be quickly installed and removed. Specifically, precise positioning is achieved through the precise fit between the arc-shaped block and the connecting groove, followed by a spring-driven automatic locking of the insertion block into the groove. This design makes the filter pipe installation process simple and reliable. When disassembly is required, simply pull the pull plate outwards, causing the connecting column to disengage the insertion block from the groove, allowing the filter pipe to be easily removed for cleaning or replacement. This structural design greatly simplifies the filter pipe maintenance process, reduces equipment downtime, improves production efficiency, and ensures the sealing and stability of the connection points.

[0012] This invention achieves convenient disassembly and assembly of the filter tube through the positioning and cooperation of the arc-shaped block and the connecting groove, as well as the quick locking structure of the plug block with the plug groove under the action of the spring, which facilitates cleaning and maintenance and improves the ease of use of the equipment.

The bottom of both support columns 2 is fixedly connected to the top of the base 1. An arc plate 11 with the same auxiliary support is fixedly connected to the same side of the two support columns 2. The arc plate 11 enhances the structural stability between the two support columns 2.

[0017] A stirrer 12 is rotatably connected to the top of the tank body 4. The stirrer 12 is used to agitate the liquid in the tank to promote mixing and filtration. A rotating plate 13 is fixedly connected to the bottom of the stirrer 12. The rotating plate 13 rotates synchronously with the stirrer 12 to expand the stirring range. A motor 5 is fixedly connected to the top of the tank body 4 to drive the stirrer 12 to rotate. The motor 5 provides rotational power for the stirrer 12. A discharge pipe 7 is fixedly connected to the bottom of the tank body 4 and communicates with its interior. The discharge pipe 7 is used to introduce the liquid in the tank into the filtration section.

[0018] A filter tube 8 is fitted onto the bottom of the feed pipe 7 and secured by two fixing mechanisms. These mechanisms enable a detachable connection between the feed pipe 7 and the filter tube 8. Each fixing mechanism includes an arc-shaped block 14 fixedly connected to one side of the feed pipe 7. The arc-shaped block 14 is used for positioning and docking with the filter tube 8. A connecting groove 22 is formed at the top of the filter tube 8, matching the size of the lower end of the arc-shaped block 14. The lower end of the arc-shaped block 14 is inserted into the connecting groove 22, which accommodates the lower end of the arc-shaped block 14 for initial alignment. An insertion groove 15 is formed on one side of the lower end of the arc-shaped block 14. A support frame 16 is fixedly connected to the outer wall of the tube 8. The support frame 16 provides an installation base for the plug-in structure. A plug-in block 21 is slidably connected inside the support frame 16 via a spring 19. The plug-in groove 15 is used to accommodate the plug-in block 21 to achieve locking. The spring 19 provides a continuous locking force to the plug-in block 21.
