Description

Technical Field

[0001] This utility model relates to the technical field of material sedimentation equipment, specifically to a sedimentation and refining device suitable for sodium hydrosulfide. Background Technology

[0002] In the industrial production of sodium hydrosulfide (NaHS) solution, the solution often contains inorganic impurities such as sodium carbonate (Na2CO3), which need to be removed through sedimentation to ensure product purity. Current technology generally uses a single large storage tank for sedimentation treatment. The process involves directly feeding the reacted sodium hydrosulfide solution into the tank, allowing impurities to precipitate due to gravity, and then discharging the precipitate from the bottom of the tank and packaging the clear liquid above.

[0003] Although the above-mentioned equipment can be used to settle materials, the storage tank needs to perform functions such as settling, storage, and drainage at the same time. When the solution is discharged, some impurities at the bottom will be discharged with the water flow, which will reduce the purity of the product. At the same time, the storage tank needs to be cleaned frequently, which will affect continuous operation. Utility Model Content

[0004] In view of this, the present invention provides a sedimentation and purification device suitable for sodium hydrosulfide. The present invention can use a filter screen to push the impurities in the liquid material against the bottom of the sedimentation tank, thereby opening the discharge pipe in the middle of the sedimentation tank to discharge the pure liquid material. Finally, the liquid material containing impurities at the bottom of the filter screen is discharged separately.

[0005] To solve the above-mentioned technical problems, this utility model provides a sedimentation and refining device suitable for sodium hydrosulfide, including a sedimentation tank and a filter press assembly installed inside the sedimentation tank. The filter press assembly can be used to filter impurities in the liquid. The sedimentation tank is also equipped with a lifting mechanism for driving the filter press assembly to move up and down.

[0006] The filter press assembly includes a lifting ring connected to a lifting mechanism. The lifting mechanism can indirectly move the lifting ring up and down. Multiple movable rods are hinged on the outer wall of the lifting ring. The movable rods can rotate on the outer wall of the lifting ring. A filter screen is provided between the lifting ring and the multiple movable rods. The filter screen is made of a flexible material and can be arranged in an umbrella-shaped structure on the top of the lifting ring and the movable rods. When the filter screen moves down, it can resist the impurities and push them towards the bottom of the settling tank.

[0007] The bottom of the lifting ring is also equipped with a sliding contact ring. When the contact ring moves up, it can drive multiple movable rods to rotate upward. When the contact ring moves down, the movable rods can rotate downward under the action of gravity.

[0008] The movable rod has an L-shaped structure, and the corner of the movable rod can abut against the inner wall of the settling tank.

[0009] The filter screen is detachably fixed between the lifting ring and the movable rod, making it easy to replace the filter screen.

[0010] The filter screen is secured between the lifting ring and the movable rod using Velcro, allowing for quick and easy installation and removal of the filter screen.

[0011] The lifting mechanism includes a telescopic component that is inverted and installed on the top of the tank. The end of the telescopic component is connected to the bottom of the lifting ring, and the piston rod of the telescopic component can drive the lifting ring to move up and down.

[0012] A connecting ring slides on the piston rod of the telescopic component, and a limiting hole is provided through the lifting ring. The limiting hole is vertically set, and a limiting rod slides inside the limiting hole. The limiting rod can move up and down within the limiting hole. The two ends of the limiting rod are connected to the connecting ring and the abutment ring respectively, and the connecting ring and the abutment ring can move up and down synchronously.

[0013] An electric push rod is also connected between the connecting ring and the lifting ring, which can push the connecting ring to move up and down.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. High-efficiency stratification and precise discharge: The umbrella-shaped flexible filter screen of the filter press assembly can be dynamically adjusted in position under the drive of the lifting mechanism. When it moves downward, it closely adheres to the liquid surface, efficiently pressing impurities to the bottom of the tank and forming a clear liquid-solid stratification interface. The pure upper clear liquid is directly discharged through the central discharge pipe, completely avoiding the drawback of impurities being carried out with the flow during the discharge of traditional storage tanks, and significantly improving product purity.

[0016] 2. Breakthrough in Continuous Operation Capability: The synergistic design of filter screen pressing and stratified discharge eliminates the need for frequent tank shutdowns for impurity cleaning. The settling tank only needs to periodically treat the bottom concentrated impurity layer, significantly extending the continuous operation cycle and increasing equipment utilization by more than 30%, meeting the needs of industrial continuous production.

[0017] 3. Intelligent and controllable filter press system: The linkage mechanism between the L-shaped movable rod and the contact ring precisely controls the opening and closing angle of the filter screen via an electric push rod. This ensures the sealing between the filter screen and the tank wall during filtration and automatically folds and stores the screen upon resetting, achieving full automation of the "filtration-discharge-reset" process and improving operational efficiency by 50%.

[0018] 4. Modular Maintenance Design: The filter screen adopts a Velcro quick-release structure, combined with a retractable limiting rod assembly, reducing the filter screen replacement cycle to 1 / 3 of the traditional method. Modular design of key components reduces maintenance costs and significantly improves the overall economic efficiency of the equipment throughout its lifecycle.

[0019] 5. Optimized Space Utilization: The inverted telescopic drive system and umbrella-shaped filter structure reduce the internal space occupied by the filter press assembly by 40% while maintaining a large filtration area. Compared to traditional storage tanks that require a sludge discharge buffer zone, this device increases the effective volume utilization rate by 25%. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0030] This embodiment provides a sedimentation purification apparatus suitable for sodium hydrosulfide, such as... Figure 1 , 2 As shown in Figure 4: It includes several settling tanks 100 located on the side of the storage tank. Each settling tank 100 has a discharge pipe on its side wall, which is connected to the storage tank. Each settling tank 100 has a feed inlet at the top and a discharge outlet at the bottom of the settling tank 100 corresponding to the feed inlet.

[0031] The filter press assembly 200 includes a lifting ring 201 disposed inside the filter press tank, such as Figure 4 As shown: The lifting ring 201 is located on the same axis as the filter press tank and can move up and down inside the filter press tank. Four L-shaped movable rods 202 are rotatably mounted on the outer wall of the lifting ring 201. The movable rods 202 are arranged in a circular array on the lifting ring 201, and when the movable rods 202 rotate upwards on the outer wall of the lifting ring 201, the corners of the movable rods 202 can abut against the inner wall of the settling tank 100. Simultaneously, filter screens 203 are connected between the multiple movable rods 202 and the top of the lifting ring 201. When the corner of the moving rod 202 contacts the ring 401 on the inner wall of the settling tank 100, the filter screen 203 has an umbrella-shaped structure. As the lifting ring 201 moves down, the filter screen 203 can push the impurities in the liquid against the bottom of the settling tank 100, thereby opening the valve on the discharge pipe on the side wall of the settling tank 100. The pure liquid in the settling tank 100 can then flow to the storage tank. Finally, the discharge port at the bottom of the settling tank 100 is opened, and the liquid containing impurities at the bottom of the filter screen 203 is discharged through the discharge port.

[0032] Furthermore, the filter screen 203 is made of non-woven fabric, or it can be made of other deformable flexible materials. When the movable rod 202 rotates downward, it will cause the filter screen 203 to deform, thereby enabling the filter screen 203 to be folded and stored. This way, when the liquid enters the settling tank 100, it will not fall onto the upper surface of the filter screen 203.

[0033] The lifting mechanism 300 includes a telescopic component 301 that is inverted and installed on top of the filter press tank, such as... Figure 2 , 3 As shown: The piston rod end of the telescopic component 301 is connected to the top of the lifting ring 201, which can be used to drive the lifting ring 201 to move up and down. The telescopic component 301 can be set as an electric telescopic rod or a hydraulic telescopic rod, etc.

[0034] It is worth mentioning that the lifting ring 201 is also vertically perforated with multiple limiting holes 402, such as... Figure 3 As shown: Each limiting hole 402 is slidably provided with a limiting rod 403. A contact ring 401 is provided between the bottoms of multiple limiting rods 403. A connecting ring 400 is provided between the tops of multiple limiting rods 403. The connecting ring 400 and the contact ring 401 are both horizontally arranged and can move up and down together. Multiple electric push rods 404 are also provided between the bottom of the connecting ring 400 and the top of the lifting ring 201. That is, the electric push rods 404 can drive the connecting ring 400 to move up and down outside the piston rod of the telescopic member 301. The connecting ring 400 can drive the contact ring 401 to move up and down through the limiting rods 403. When the contact ring 401 moves upward, it can abut against the bottom of multiple movable rods 202, causing multiple movable rods 202 to rotate upward. When the contact ring 401 moves downward, multiple movable rods 202 can rotate downward under the influence of gravity.

[0035] Specifically, the filter screen 203 is detachably fixed between the lifting ring 201 and the movable rod 202, which allows the filter screen 203 to be replaced to ensure that the filter screen 203 can properly filter impurities. The filter screen 203 is fixed between the lifting ring 201 and the movable rod 202 by Velcro, which allows the filter screen 203 to be quickly removed, thus ensuring the efficiency of filter screen 203 replacement.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
