Description

Technical Field

[0001] This utility model relates to the field of reaction mixing technology, and in particular to an auxiliary automated solid-liquid separation stirrer. Background Technology

[0002] Solid-liquid separation is a common step in chemical reactions, especially in systems involving solid catalysts and liquid reactants. Traditional stirrers often fail to effectively achieve uniform catalyst distribution and post-reaction separation, resulting in low reaction efficiency and complex operation. While existing solid-liquid separation stirrers have addressed some of these issues, they still have many shortcomings. Some stirrers cannot be automated, requiring frequent manual intervention, increasing labor intensity and operational risks; some stirrers have unreasonable structural designs, resulting in insufficient contact area between the catalyst and liquid reactants, leading to incomplete reactions; and some stirrers have poor sealing performance, easily causing reactant leakage, environmental pollution, and even safety accidents. Therefore, developing a stirrer that can efficiently and automatically achieve solid-liquid separation is of great significance. Utility Model Content

[0003] This invention provides an auxiliary automated solid-liquid separation stirrer, which aims to solve the problems mentioned above, such as the need for solid-liquid separation in the catalytic reaction of liquid reactants with solid catalysts, the inability of common stirrers to automatically separate while ensuring the reaction contact area, and the difficulty in disassembly and handling.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An auxiliary automated solid-liquid separation stirrer includes a hollow storage chamber. The top and bottom of the storage chamber are coaxially provided with rotating shafts. The side wall of the storage chamber is provided with several fan blade slots that communicate with the inside of the chamber. Hollow fan blades are detachably fixed in the fan blade slots and communicate with the storage chamber through the fan blade slots. The fan blade has several small holes on both sides. A filter slot is provided on the inner side of the fan blade near the small holes. A filter is detachably fixed in the filter slot to block the small holes. The outside of the fan blade communicates with the inside of the fan blade after passing through the small holes and the filter in sequence.

[0005] Preferably, the storage cavity is a hollow cylinder, and the rotating shaft is coaxially fixedly connected to the top and bottom of the storage cavity, and the rotating shaft and the storage cavity cooperate to form a roller-shaped structure.

[0006] More preferably, the fan blade slots are evenly distributed around the central axis of the storage cavity, and each fan blade slot protrudes outward along the storage cavity. The fan blades and fan blade slots correspond one-to-one and are embedded and mated in the corresponding fan blade slots.

[0007] Furthermore, the fan blade includes a hollow plate with an opening at one end. The end of the hollow plate on the opening side is embedded in the fan blade slot. The fan blade slot is provided with a plurality of first screw holes. The end of the hollow plate on the opening side is provided with second screw holes that correspond one-to-one with the first screw holes. After the first screw holes and the second screw holes correspond, they are fastened together by the same fastening screw.

[0008] Furthermore, the hollow plate is provided with several small holes evenly distributed on both the front and rear sides symmetrical about the opening, and the filter slot is located inside the hollow plate near the front and rear sides.

[0009] Specifically, the filter slot is formed by two horizontal plates and one vertical plate in conjunction with a hollow plate. The vertical plate is fixedly connected to the inner wall of the hollow plate with small holes on the side near the opening, and the vertical plate is arranged opposite to the opening. The vertical plate and the inner wall of the hollow plate on the side away from the opening are enclosed by the horizontal plates to form the filter slot. The filter is embedded in the filter slot to block all the small holes on the corresponding side. The two horizontal plates are respectively located at the top and bottom of the vertical plate, and one end of the horizontal plate is fixedly connected to the vertical plate, and the other end of the horizontal plate is fixedly connected to the inner wall of the hollow plate on the side away from the opening.

[0010] More specifically, the filter is a micron-sized filter.

[0011] More specifically, the top of the hollow plate is also provided with an opening, and the top opening has a recessed mounting port. A top plate is embedded in the mounting port to seal the top opening. After the top plate and the mounting port are embedded, the hollow plate fits with the fan blade slot. The top plate and the mounting port are provided with corresponding concealed screw holes, and concealed screws are threaded into the concealed screw holes. The top plate and the mounting port are concealed and fixed by the concealed screws.

[0012] Furthermore, each of the fan blade slots is a square ring, and the hollow plate is a rectangular hollow plate structure corresponding to the fan blade slot.

[0013] Preferably, the top of the storage cavity is provided with a flange-shaped feeding port, and an end cap for sealing is detachably provided at the feeding port by fasteners.

[0014] The beneficial effects of this utility model are: (1) This utility model uses an external drive device to drive the rotating shaft and thus drive the main body of the stirrer, so that the stirring process is fully automated and the speed is adjustable; (2) This utility model adopts a solid-liquid separation method. The catalyst is put into the cavity structure through the feed port. The catalyst is dispersed into the fan blade by rotation and blocked by the micron-level filter. The raw material enters the fan blade through the small hole and the micron-level filter to contact the catalyst and react. The reaction is more complete with the stirring of the stirrer. (3) This utility model adopts detachable components, which are convenient to assemble, replace and clean during use. Different specifications of filter screens can also be selected according to the average diameter of the catalyst. Attached Figure Description

[0016] The embodiments will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 5 As shown in the preferred embodiment 1, an auxiliary automated solid-liquid separation stirrer includes a hollow storage cavity 1. The top and bottom of the storage cavity 1 are coaxially provided with a rotating shaft 2. The side wall of the storage cavity 1 is provided with a plurality of fan blade slots 3 that communicate with the cavity. Hollow fan blades 4 are detachably fixedly installed in the fan blade slots 3. The fan blades 4 communicate with the storage cavity 1 through the fan blade slots 3. The fan blade 4 has several small holes 10 on both sides. The inner side of the fan blade 4 near the small holes 10 is provided with a filter slot 6. A filter 5 is detachably fixed in the filter slot 6 to block the small holes 10. The outside of the fan blade 4 communicates with the inside of the fan blade 4 after passing through the small holes 10 and the filter 5 in sequence.

[0018] The device is connected to the output of an external drive device via a rotating shaft 2, allowing the external drive device to drive the stirring process, making the stirring process completely automatic. During stirring, the rotating shaft 2 rotates, causing the storage chamber 1 to rotate synchronously. During rotation, the catalyst in the storage chamber 1 enters each fan blade 4 under centrifugal effect. At this time, the fan blade 4 not only plays a stirring role, but also allows the liquid reactants to come into contact with the catalyst in the fan blade 4 and storage chamber 1 after passing through the small holes 10 and the filter screen 5, so that the reaction is complete. The solid catalyst cannot enter the outside through the filter screen 5. When solid-liquid separation is required after the reaction is completed, the device can be separated from the liquid surface. The reactants will flow out normally through the small holes, while the solid catalyst will be intercepted by the micron-sized filter screen 5, thus achieving automatic solid-liquid separation. The entire device is also easy to disassemble, replace, and clean.

[0019] like Figures 1-3 As shown in the preferred embodiment 2, the fan blade slots 3 are evenly distributed around the central axis of the storage cavity 1, and each fan blade slot 3 protrudes outward along the storage cavity 1. The fan blades 4 correspond one-to-one with the fan blade slots 3 and are embedded and mated in the corresponding fan blade slots 3. This ensures a tight fit between the fan blades 4 and the fan blade slots 3, preventing catalyst leakage.

[0020] The fan blade 4 includes a hollow plate 401 with an opening 407 at one end. The end of the hollow plate 401 on the side of the opening 407 is embedded in the fan blade slot 3. The fan blade slot 3 is provided with a plurality of first screw holes 301. The end of the hollow plate 401 on the side of the opening 407 is provided with second screw holes 402 that correspond one-to-one with the first screw holes 301. After the first screw holes 301 and the second screw holes 402 are aligned, they are fastened together by the same fastening screw 9.

[0021] The part with the second screw hole 402 is the fixing part of the hollow plate 401. Apart from the second screw hole 402 and the opening 407, no other devices are arranged. The fan blade 4 is fixed in the fan blade slot 3 by aligning the second screw hole 402 with the first screw hole 301 and forming a thread by the same fastening screw 9. This ensures the stability of the fan blade 4 during stirring and prevents the catalyst from leaking out. On the other hand, it facilitates disassembly and installation. It can be completely disassembled for cleaning and also facilitates operations such as replacing the filter screen 5.

[0022] like Figure 5 and Figure 6 As shown, in a preferred embodiment 3, the hollow plate 401 is provided with a plurality of small holes 10 evenly on both the front and rear sides symmetrical about the opening 407, and the filter slot 6 is provided inside the hollow plate 401 near the front and rear sides.

[0023] The filter slot 6 is formed by two horizontal plates 601 and one vertical plate 603 in conjunction with the hollow plate 401. The vertical plate 603 is fixedly connected to the inner wall of the hollow plate 401 with small holes 10 on the side near the opening 407, and the vertical plate 603 and the opening 407 are arranged opposite to each other. The vertical plate 603 and the inner wall of the hollow plate 401 on the side away from the opening 407 are enclosed by the horizontal plates 601 to form the filter slot 6. The filter 5 is embedded in the filter slot 6 to block all the small holes 10 on the corresponding side. The two horizontal plates 601 are respectively located at the top and bottom of the vertical plate 603, and one end of the horizontal plate 601 is fixedly connected to the vertical plate 603, and the other end of the horizontal plate 601 is fixedly connected to the inner wall of the hollow plate 401 on the side away from the opening 407.

[0024] Two horizontal plates 601 form a filter slot 6 between the vertical plate 603 and the inner wall of the hollow plate 401 on the side away from the opening 407. When the filter screen 5 is inserted along the filter slot 6, the filter screen 5 just covers all the small holes 10 on one side of the filter slot 6, and the internal catalyst is just blocked. By controlling the width of the filter slot 6 to be exactly the same as the thickness of the filter screen 5, it can be ensured that the filter screen 5 covers tightly. On the one hand, it prevents the solid catalyst from leaking, and on the other hand, it allows for the replacement of filter screens 5 with different filter diameters according to different catalysts. The vertical plate 603 ensures the sealing of both sides of the filter slot 6, preventing the catalyst from leaking out from the side of the filter slot 6 during movement.

[0025] Preferably, in order to ensure that there is no leakage around the filter screen 5, additional fasteners and sealing rings can be used to reinforce the four corners or edges of the filter screen 5 during installation. The sealing rings are arranged around the periphery of the filter screen 5 and the filter screen is pressed and fixed between the inner wall of the hollow plate 401 and the fasteners by the fasteners.

[0026] It should be noted that the filter here uses a relatively rigid plate-like structure, such as a micron-sized metal filter, to ensure stable filtration after insertion.

[0027] In the above embodiments, more preferably, the filter 5 is a micron-sized filter. This ensures effective interception of the solid catalyst; the specific filter diameter is selected based on the catalyst used, ensuring that the catalyst cannot leak from the filter 5.

[0028] like Figures 4-6As shown in the preferred embodiment 4, the top of the hollow plate 401 is also provided with an opening 407. The opening 407 at the top is provided with a recessed mounting port 403. A top plate 404 is embedded in the mounting port 403 to seal the opening 407 at the top. After the top plate 404 and the mounting port 403 are embedded, the hollow plate 401 remains in contact with the fan blade slot 3. The top plate 404 and the mounting port 403 are each provided with a corresponding concealed screw hole 405. The concealed screw hole 405 is threaded with a concealed screw 406. The top plate 404 and the mounting port 403 are concealed and fixedly installed by the concealed screw 406.

[0029] Ensure that the top plate 404 is indistinguishable from the original hollow plate 401 after installation, forming an invisible fixed installation, so that it can be smoothly and seamlessly installed in the corresponding fan blade slot 3. At the same time, the top plate 404 can be removed by loosening the invisible screw 406. After the top plate 404 is opened, the inside can be cleaned or the filter screen 5 can be replaced.

[0030] In the above embodiments, more preferably, the opening 407 at the top of the hollow plate 401 is connected with the opening 407 at the fixing part of the hollow plate 401 to form a complete opening 407, which does not affect the specific installation of the device, and at the same time facilitates observation and operation of the interior.

[0031] like Figures 1-6 As shown in the preferred embodiment 4, the storage cavity 1 is a hollow cylinder, and the rotating shaft 2 is coaxially fixedly connected to the top and bottom of the storage cavity 1, respectively, and the rotating shaft 2 and the storage cavity 1 cooperate to form a roller-like structure. This ensures the stability of rotation and is used to stably achieve stirring.

[0032] Each of the aforementioned fan blade slots 3 is a square ring, and the hollow plate 401 is a rectangular hollow plate structure corresponding to the fan blade slot 3. This facilitates installation and operation.

[0033] In the above embodiments, as a more preferred embodiment, the hollow plate 401 can also be set as an arc-shaped plate structure in order to reduce the stirring resistance, as long as the fixing part of the hollow plate 401 and the fan blade slot 3 are matched. The filter part can be set according to the situation, and the top plate 404 and other components also need to be adapted according to the request, but the original design and function are retained.

[0034] like Figure 1 As shown, in a preferred embodiment 4, the top of the storage cavity 1 is provided with a flange-shaped feeding port 7, and an end cap 8 for sealing is detachably provided at the feeding port 7 by means of fasteners.

[0035] Before use, add solid catalyst into storage chamber 1 through end cap 8. After addition, seal the chamber with end cap 8 and finally seal and tighten it with fasteners to ensure airtightness. Solid catalyst can only move within storage chamber 1, fan blade slot 3, and fan blade 4.

[0036] The working principle of this utility model: The device is connected to the output of an external drive device via a rotating shaft 2, allowing the external drive device to drive the stirring process, making the stirring process completely automatic. During stirring, the rotating shaft 2 rotates, causing the storage chamber 1 to rotate synchronously. During rotation, the catalyst in the storage chamber 1 enters each fan blade 4 under centrifugal effect. At this time, the fan blade 4 not only plays a stirring role, but also allows the liquid reactants to come into contact with the catalyst in the fan blade 4 and storage chamber 1 after passing through the small holes 10 and the filter screen 5, so that the reaction is complete. The solid catalyst cannot enter the outside through the filter screen 5. When solid-liquid separation is required after the reaction is completed, the device can be separated from the liquid surface. The reactants will flow out normally through the small holes, while the solid catalyst will be intercepted by the micron-sized filter screen 5, thus achieving automatic solid-liquid separation. The entire device is also easy to disassemble, replace, and clean.
