Description

Technical Field

[0001] The utility model relates to the technical field of chemical precipitation, in particular to a chemical sedimentation diversion device. Background Art

[0002] In my country's chemical production process, it is often necessary to statically stratify some materials in the production process. The upper supernatant of the sedimentation equipment can be used in the next process, and the lower sedimentation material can also be sent to the subsequent separation process; if the material after stratification is only processed once, the utilization efficiency of the sedimentation equipment will be limited. In order to improve the utilization efficiency of the sedimentation equipment, during the static period of the sedimentation equipment, a small amount of raw material liquid will be continuously injected into the sedimentation equipment and the upper clear liquid will be sucked out, which can realize continuous static stratification treatment to improve the utilization efficiency of the sedimentation equipment.

[0003] The existing technology is to inject material from the top pipe mouth of the sedimentation equipment, or extend the top pipe mouth of the sedimentation equipment to the bottom of the sedimentation equipment. In both methods, the raw material liquid directly impacts the original static material. When the feed flow rate and flow rate are too large, the sedimented material at the bottom of the sedimentation equipment will surge, causing the liquid inside the entire sedimentation equipment to become turbid, prolonging the time required for static sedimentation again, and also affecting the subsequent use of the upper clear liquid; in order to prevent the sedimented material at the bottom of the sedimentation equipment from surging, the feed flow rate and flow rate are reduced. Although this method can reduce the surging of the material, it also indirectly increases the time required for production operation and reduces production efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a chemical sedimentation diversion device to solve the problem that when adding materials to the bottom of the sedimentation equipment, the feed flow rate and flow velocity are too large, causing the sedimented materials at the bottom of the sedimentation equipment to surge, and the feed flow rate and flow velocity are very small, which reduces production efficiency.

[0005] In order to solve the above problems, the technical solutions provided are as follows:

[0006] A chemical sedimentation diversion device includes a diversion pipe extending from the top of the sedimentation equipment into the bottom of the sedimentation equipment, the upper end of the diversion pipe is a liquid inlet, the liquid inlet is provided with a valve, the inner wall of the diversion pipe is provided with spiral plates distributed from top to bottom, the bottom end of the diversion pipe is connected to a reducer, the bottom end of the reducer is fixedly connected to a reflective plate tie rod, the bottom end of the reflective plate tie rod is fixedly connected to the reflective plate, and the reflective plate is suspended at the bottom of the sedimentation equipment.

[0007] The basic principle of the above technical solution is: open the valve at the liquid inlet, the liquid material first enters the guide pipe through the liquid inlet, the spiral plate in the guide pipe can change the flow direction of the material, reduce the flow rate of the liquid material, and then pass through the lower reducer to further reduce the flow rate of the material, and finally flow to the reflective plate at the bottom. The reflective plate allows the liquid material to disperse around the sedimentation equipment before flowing into the bottom of the equipment, alleviating the impact of the liquid material on the deposited material at the bottom of the equipment, and avoiding the liquid flow directly impacting the deposited material at the bottom, causing a large amount of deposited material to surge, causing the material to become turbid.

[0008] The beneficial effect of the above technical solution is that: compared with the existing material raw liquid directly impacting the original static material at the bottom of the sedimentation equipment, this technical solution does not need to reduce the feed flow rate. The spiral plate in the guide pipe and the reducer at the bottom will first buffer the liquid material flow rate, and the reflector will then disperse the liquid material from the surrounding areas of the sedimentation equipment into the bottom of the equipment, thereby alleviating the impact of the liquid material on the deposited material at the bottom of the equipment, and avoiding the large-scale surging of the deposited material at the bottom of the sedimentation equipment, which not only reduces the time required for production operations, but also improves production efficiency.

[0009] Furthermore, the reducer is a multi-stage reducer, the diameter of which gradually increases from top to bottom. The cross-sectional area of ​​the multi-stage reducer gradually increases from top to bottom, and when the liquid flow rate remains unchanged, the flow rate will inevitably decrease.

[0010] Furthermore, the reflector is conical in shape, with an upwardly protruding center and downwardly inclined edges. The raw material liquid flowing out of the reducer nozzle directly impacts the reflector, flows from the protruding center of the reflector to its edges, and then flows into the sedimentation device for stagnant rest, thereby preventing the raw material liquid from directly impacting the bottom of the sedimentation device.

[0011] Furthermore, the valve is an electric valve, which is connected to a controller to conveniently control the opening and closing of the electric valve.

[0012] Furthermore, the reducer has a downwardly extending reflector tie bar fixedly connected to each of the four front, rear, left, and right sides of the bottom end. The bottom ends of the four reflector tie bars are fixedly connected to the edges of the reflector. The reflector tie bars securely suspend the reflector below the reducer, allowing the raw material solution, buffered by the reflector, to flow into the sedimentation device through the gaps between the four reflector tie bars.

[0013] Furthermore, a support lug is fixedly connected to the upper portion of the outer wall of the guide tube, and the support lug is supported on the top of the sedimentation device. The support lug places the entire guide device in the sedimentation device to prevent the guide device from falling to the bottom of the sedimentation device. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following is further described in detail through specific implementation methods:

[0017] The embodiment is basically as shown in the attached Figure 1 As shown:

[0018] A chemical sedimentation diversion device includes a diversion pipe 2 extending from the top of a sedimentation device 1 into the bottom of the sedimentation device 1, a support ear plate 3 is welded on the upper part of the outer wall of the diversion pipe 2, and the support ear plate 3 is supported on the top of the sedimentation device 1. The upper end of the diversion pipe 2 is a liquid inlet, and an electric valve 4 is provided at the liquid inlet. The electric valve 4 is electrically connected to a controller (not shown in the figure). The inner wall of the diversion pipe 2 is provided with a spiral plate 5 spirally distributed from top to bottom. The bottom end of the diversion pipe 2 is connected to a reducer, and the reducer includes a primary reducer 6 and a secondary reducer 7. The primary reducer 6 and the secondary reducer The diameter of the reducer 7 gradually increases from top to bottom. The top of the first-level reducer 6 is the same diameter as the bottom end of the guide pipe 2 and is fixedly connected. The top of the second-level reducer 7 is the same diameter as the bottom end of the first-level reducer 6 and is fixedly connected. A downward-extending reflector reinforcement 8 is fixedly connected to the four directions of the front, back, left and right of the bottom end of the second-level reducer 7. The reflector reinforcements 8 in the four directions are fixedly connected together with a reflector 9. The reflector 9 is a cone shape. The center of the reflector 9 bulges upward, and the edge of the reflector 9 is tilted downward. The reflector 9 is suspended at the bottom of the precipitation equipment 1.

[0019] The specific implementation process is as follows:

[0020] The controller opens the valve at the liquid inlet, and the liquid material first enters the guide pipe 2 through the liquid inlet. The spiral plate 5 in the guide pipe 2 can change the flow direction of the material and reduce the flow rate of the liquid material. Then the material flows through the lower first-level reducer 6 and the second-level reducer 7 to further reduce the flow rate of the liquid material, and finally flows to the reflector 9 at the bottom. Figure 1The liquid material is dispersed around the sedimentation equipment 1 first and then flows into the bottom of the equipment in the direction of the arrow, which alleviates the impact of the liquid material on the sediment in the bottom of the equipment, avoids the direct impact of the liquid flow on the sediment in the bottom, and thus avoids causing the sediment to surge and the material to become turbid. The device does not need to reduce the flow rate of the feed, the spiral plate 5 in the flow guide pipe 2 and the variable-diameter pipe at the bottom end will first buffer the flow rate of the liquid material, the reflection plate 9 will then disperse the liquid material to flow into the bottom of the equipment from around the sedimentation equipment 1, which alleviates the impact of the liquid material on the sediment in the bottom of the equipment, avoids causing the sediment in the bottom of the sedimentation equipment 1 to surge, reduces the time required for production operation, and improves the production efficiency.
