Description

Technical Field

[0001] This utility model relates to the field of chemical process equipment, and in particular to a resin intermediate filter. Background Technology

[0002] Resin intermediate filters are industrial purification devices used in the production of synthetic resins. Their function is to remove various solid impurities from the resin liquid during the production process, ensuring the purity and quality of the final product and guaranteeing the stability and continuity of the production process.

[0003] Traditional resin intermediate filters directly filter the resin concentrate using a filter screen. Large particles of waste in the resin concentrate clog the filter screen, reducing its throughput and resulting in poor filtration performance. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a resin intermediate filter, which aims to improve the problem that traditional resin intermediate filters directly filter resin concentrate using a filter screen, causing large particles of waste in the resin concentrate to clog the filter screen, resulting in poor filtration effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a resin intermediate filter, comprising a filter barrel, a barrel cover fixedly connected to the top of the filter barrel, a spiral distributing pipe fixedly connected to the inner wall of the filter barrel, a feed pipe fixedly connected to the top of the spiral distributing pipe, the feed pipe penetrating through the filter barrel, a first distributing pipe and a second distributing pipe fixedly connected to the bottom of the spiral distributing pipe, the second distributing pipe penetrating through the filter barrel, a filter media plate fixedly connected to the inner wall of the filter barrel, and a discharge mechanism fixedly connected to the bottom of the filter barrel.

[0006] By adopting the above solution, the pressure of the conveying liquid and the spiral distribution pipe are used to make the resin liquid rotate at high speed in the pipeline to obtain centrifugal force. The centrifugal force separates the clear liquid and large particle waste of the resin liquid. The clear liquid is then transported to the filter plate through the first distribution pipe, and the large particles are transported to the waste bin through the second distribution pipe. This improves the problem of traditional resin intermediate filter machines directly filtering resin liquid with filter screens, where large particle waste in the resin liquid clogs the filter screens, reducing the filter screen throughput and thus leading to poor filtration effect.

[0007] Preferably, the discharge mechanism includes a bottom cover, a discharge pipe is fixedly connected to the bottom end of the bottom cover, an outer shell is fixedly connected to the outer wall of the filter barrel, the discharge pipe passes through the outer shell, and a valve is fixedly connected to the outer wall of the discharge pipe.

[0008] Preferably, a partition is fixedly connected to the bottom end of the outer shell, and a waste outlet is provided inside the partition.

[0009] Preferably, a waste bin is fixedly connected to the bottom surface of the partition, a through groove is provided between the two waste bins, a first rotating shaft is fixedly connected to the side wall of the waste bin, the first rotating shaft is located in the through groove, a baffle is rotatably connected to the outer wall of the first rotating shaft, and limit strips are provided on both sides of the baffle. The limit strips are fixedly connected to the inner wall of the waste bin near the baffle and are located at the upper part of the through groove.

[0010] Preferably, a support block is fixedly connected to the inner bottom surface of each of the two waste bins, a second rotating shaft is fixedly connected to the top surface of the support block, a rotating plate is rotatably connected to the outer wall of the second rotating shaft, a third rotating shaft is fixedly connected to the end of the rotating plate away from the second rotating shaft, a connecting rod is rotatably connected to the outer wall of the third rotating shaft, a float is fixedly connected to the end of the connecting rod away from the third rotating shaft, a traction rope is fixedly connected to the end of the rotating plate near the baffle, and the end of the traction rope away from the rotating plate is fixedly connected to the outer wall of the baffle.

[0011] Preferably, a siphon pipe is fixedly connected to the outer wall of the waste bin, the siphon pipe penetrates the outer wall of the waste bin, a liquid collection pipe is fixedly connected to the end of the siphon pipe away from the partition, and a drain pipe is fixedly connected to the end of the liquid collection pipe away from the siphon pipe.

[0012] Preferably, the top of the outer casing has a bolt hole, and a lifting ring is threaded onto the inner wall of the bolt hole.

[0013] Preferably, a base is fixedly connected to the bottom of the partition.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the pressure of the conveying liquid and the spiral distribution pipe cause the resin liquid to rotate at high speed in the pipe to obtain centrifugal force. The centrifugal force separates the clear liquid and large particles of the resin liquid. The clear liquid is then transported to the filter plate through the first distribution pipe, and the large particles of waste are transported to the waste bin through the second distribution pipe. This improves the problem of traditional resin intermediate filter machines directly filtering resin liquid with a filter screen, where large particles of waste in the resin liquid clog the filter screen, reducing the filter screen's throughput and thus leading to poor filtration effect.

[0016] 2. In this utility model, the float rises as the liquid in the waste bin rises, thereby driving the baffle to turn and direct the liquid to another waste bin. The siphon pipe automatically drains the liquid when it is overflowed, so that the waste bin is automatically drained when it is full without manual intervention. This improves the problem that when the machine is full of waste, it is necessary to manually stop the machine and open the valve to release the waste, which leads to increased labor costs and reduced machine efficiency.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figures 1-3The present invention provides an embodiment of a resin intermediate filter, comprising a filter barrel 1, a barrel cover 2 fixedly connected to the top of the filter barrel 1, a spiral distribution pipe 5 fixedly connected to the inner wall of the filter barrel 1, a feed pipe 4 fixedly connected to the top of the spiral distribution pipe 5, the feed pipe 4 penetrating the filter barrel 1, a first distribution pipe 6 and a second distribution pipe 7 fixedly connected to the bottom of the spiral distribution pipe 5, the second distribution pipe 7 penetrating the filter barrel 1, a filter media plate 8 fixedly connected to the inner wall of the filter barrel 1, and a discharge mechanism fixedly connected to the bottom of the filter barrel 1.

[0027] Specifically, filter barrel 1 is used to install the barrel cover 2, spiral distribution pipe 5, filter media plate 8, and discharge mechanism. It also houses the inlet pipe 4 and the second distribution pipe 7. The spiral distribution pipe 5 provides centrifugal force to the resin concentrate during rotation, causing the lighter clear liquid and heavier impurities to move towards the inner and outer walls respectively, thus separating the resin concentrate from large particles such as gel and fibers. This achieves preliminary purification and reduces the burden on the filter media plate 8. The inlet pipe 4 transports the resin concentrate and applies pressure to the filter barrel 1 to increase its initial velocity, thereby increasing the centrifugal force and improving filtration efficiency. The first distribution pipe 6 transports the clear liquid, and the second distribution pipe... Pipe 7 can transport impurities, thus improving the entire coarse separation process; filter plate 8 is used for fine separation of the separated resin liquid, thereby removing most of the impurities and further improving the purity of the resin liquid; the pressure of the conveying liquid and the spiral distribution pipe 5 cause the resin liquid to rotate at high speed in the pipe to obtain centrifugal force, which separates the clear liquid and large particles of the resin liquid. The clear liquid is then transported to filter plate 8 through the first distribution pipe 6, and the large particles of waste are transported to waste bin 17 through the second distribution pipe 7. This improves the problem of traditional resin intermediate filter machines directly filtering resin liquid with filter screen, where large particles of waste in the resin liquid clog the filter screen, reducing the filter screen throughput and resulting in poor filtration effect.

[0028] Reference Figure 2 The discharge mechanism includes a bottom cover 9, a discharge pipe 10 is fixedly connected to the bottom end of the bottom cover 9, an outer shell 3 is fixedly connected to the outer wall of the filter barrel 1, the discharge pipe 10 passes through the outer shell 3, and a valve 11 is fixedly connected to the outer wall of the discharge pipe 10.

[0029] Specifically, the bottom cover 9 has a conical structure design, which allows for the collection of filtrate, accelerates the flow of filtrate, and improves the working efficiency of the filter. The outer shell 3 serves to fix and support the filter barrel 1, as well as to install the partition 12 and isolate the internal and external environments, thereby preventing filtrate and waste from leaking out and causing pollution. It also serves to guide the waste liquid, thus transporting the waste discharged from the second distribution pipe 7 to the bottom. The discharge pipe 10 is used to guide the filtrate, and the valve 11 is used to open and close the discharge pipe 10, thereby improving the controllability of the filter.

[0030] Reference Figures 1-4 The bottom of the outer shell 3 is fixedly connected to a partition 12, and a waste outlet 13 is opened inside the partition 12.

[0031] Specifically, the partition 12 is used to open the waste outlet 13; the waste outlet 13 is used to transport the waste liquid to the bottom structure and control the flow rate of the waste liquid.

[0032] Reference Figures 4-6 The bottom surface of the partition 12 is fixedly connected to a waste bin 17. A through groove 16 is provided between the two waste bins 17. A first rotating shaft 15 is fixedly connected to the side wall of the waste bin 17. The first rotating shaft 15 is located inside the through groove 16. A baffle 14 is rotatably connected to the outer wall of the first rotating shaft 15. Limiting strips 20 are provided on both sides of the baffle 14. The limiting strips 20 are fixedly connected to the inner wall of the waste bin 17 near the baffle 14. The limiting strips 20 are located at the upper part of the through groove 16.

[0033] Specifically, the two waste bins 17 are used to store waste liquid; the through channel 16 is used to install the first rotating shaft 15 and the baffle 14; the first rotating shaft 15 is used to install the baffle 14 and limit the position of the baffle 14; the baffle 14 is used to divert the waste liquid and isolate the waste bins 17 in the draining state from the waste liquid; the limiting strip 20 can intercept the baffle 14, thereby limiting the position of the baffle 14, and thus preventing the baffle 14 from rotating excessively and causing the waste liquid to flow into the two waste bins 17, causing the automatic circulation draining function to malfunction.

[0034] Reference Figures 5-6 The inner bottom surfaces of the two waste bins 17 are fixedly connected to support blocks 25. The top surface of the support blocks 25 is fixedly connected to a second rotating shaft 24. The outer wall of the second rotating shaft 24 is rotatably connected to a rotating plate 23. The end of the rotating plate 23 away from the second rotating shaft 24 is fixedly connected to a third rotating shaft 26. The outer wall of the third rotating shaft 26 is rotatably connected to a connecting rod 27. The end of the connecting rod 27 away from the third rotating shaft 26 is fixedly connected to a float 28. The end of the rotating plate 23 near the baffle 14 is fixedly connected to a traction rope 18. The end of the traction rope 18 away from the rotating plate 23 is fixedly connected to the outer wall of the baffle 14.

[0035] Specifically, the support block 25 is used to install the second rotating shaft 24, the second rotating shaft 24 is used to install the rotating plate 23, the rotating plate 23 is used to install the third rotating shaft 26 and the traction rope 18, and by rotating around the second rotating shaft 24, it plays the role of converting power and assisting in completing the self-circulating drainage function; the third rotating shaft 26 is used to install the connecting rod 27 and limit the position of the connecting rod 27, the connecting rod 27 is used to install the float 28, the float 28 is made of lightweight hollow material, and the buoyancy generated when the waste liquid rises can drive the connecting rod 27 to rise, thereby driving the end of the rotating plate 23 near the third rotating shaft 26 to lift, so that the rotating plate 23 rotates around the second rotating shaft 24; the traction rope 18 is used to connect the rotating plate 23 and the baffle 14, and is used to transmit and convert the buoyancy of the float 28, and is also used to pull the baffle 14 when the float 28 rises, thereby automatically controlling the flow direction of the waste liquid.

[0036] Reference Figures 4-6 A siphon pipe 19 is fixedly connected to the side wall of the waste bin 17. The siphon pipe 19 penetrates the outer wall of the waste bin 17. A liquid collection pipe 21 is fixedly connected to the end of the siphon pipe 19 away from the partition 12. A drain pipe 22 is fixedly connected to the end of the liquid collection pipe 21 away from the siphon pipe 19.

[0037] Specifically, the siphon 19 is used to install the collection pipe 21 and to guide the waste liquid, thereby discharging the waste liquid. The collection pipe 21 is used to install the drain pipe 22 and store a portion of the waste liquid. By raising the liquid level in a portion of the siphon 19 located in the waste bin 17 during discharge, the waste liquid in the collection pipe 21 can be squeezed out. The waste liquid in the collection pipe 21 and the waste liquid in a portion of the siphon 19 inside the waste bin 17 form a closed space. When the waste liquid in the collection pipe 21 flows out, it can drive the flow of the waste liquid in a portion of the siphon 19 inside the waste bin 17, thereby automatically triggering a siphon effect when the liquid level rises to a specific height, thereby discharging the waste liquid from the waste bin 17. This enables the self-circulating discharge function without the need for manual switching of valve 11, thus reducing labor costs and improving the operating efficiency of the filter.

[0038] Reference Figure 1 The top of the outer casing 3 is provided with a bolt hole 29, and a lifting ring 30 is threadedly connected to the inner wall of the bolt hole 29.

[0039] Specifically, bolt hole 29 is used to install lifting ring 30, which provides a lifting point for the lifting equipment and can improve the handling efficiency of the filter; and by placing the lifting ring 30 above the center of gravity of the filter, it can make the lifting posture more stable.

[0040] Reference Figure 1 The bottom of the partition 12 is fixedly connected to the base 31.

[0041] Specifically, the base 31 can stabilize the filter, and by designing the base 31 with a circular bottom, the risk of the equipment tipping to one side can be reduced, thereby improving the safety of equipment operation.

[0042] Working principle: The raw liquid is injected through the feed pipe 4. The pressure of the raw liquid provides initial velocity, causing it to rotate at high speed after entering the spiral distribution pipe 5. During the rotation, centrifugal force separates the clear liquid from the large particles of waste. The clear liquid flows out through the first distribution pipe 6, and the large particles of waste flow out through the second distribution pipe 7. The clear liquid is further filtered in the filter plate 8 and then flows out through the discharge pipe 10. The waste liquid flows into the interior of the outer shell 3 and through the waste outlet 13 to the waste bin 17 on one side. After the waste liquid rises to a certain height, the float 28 floats up and drives the traction rope 18 down through the rotating plate 23, which in turn drives the baffle 14 to rotate, thereby diverting the waste liquid to another waste bin 17. When the waste liquid in the waste bin 17 reaches the top of the siphon tube 19, the hydraulic system will push the waste liquid into a part of the siphon tube 19 inside the waste bin 17. The liquid level in the siphon tube 19 rises and discharges the liquid in the collection pipe 21, thereby driving the waste liquid in the collection pipe 21 to flow outward and triggering a siphon effect, thereby discharging the waste liquid.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
