[0002] In specific reagent reactions, two or more reagents interact, causing solid deposits to gradually form within the reaction vessel. To achieve the reaction objective, these reactants must be separated from the deposits. For example, in the treatment of industrial wastewater, during the separation of calcium ions from the wastewater, the calcium ions react with reagents to form solid deposits, thus enabling the separation of calcium from the wastewater.

[0003] Traditional reaction equipment focuses primarily on the reaction process itself and lacks direct filtration capabilities. Therefore, after the reaction has proceeded for a period of time, additional filtration equipment is needed to filter the mixture in the reaction vessel in order to effectively separate sediments and ensure the purity of the reaction products.

[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0013] The present invention is further configured such that an outward expansion portion is fixedly connected to the lower outer periphery of the lifting cylinder, the outward expansion portion having a ring-shaped protrusion structure and a cone-shaped structure that gradually expands downward.

[0014] The invention is further configured such that a vertically penetrating channel is provided in the middle of the blocking part, and a valve device is provided in the channel. The valve device is used to adjust the opening and closing of the channel. When the lifting cylinder rises, the valve device can open the channel; when the lifting cylinder falls, the valve device can close the channel.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This embodiment discloses a vertical baffled reactor, referring to... Figures 1-4 As shown, the device includes a tank body 1, the lower part of which has a tapered portion 101 that gradually tapers towards the center. A top cover 102 is provided on the upper part of the tank body 1, and the top cover 102 has several material inlets. A drive motor 3 is provided on the upper part of the top cover 102. A rotating shaft 301 is rotatably connected inside the tank body 1. The rotating shaft 301 is vertical, and its upper end is driven by the drive motor 3.

[0031] The tank body 1 has an intermediate cylinder 4 inside, which is fixedly installed inside the tank body 1 by a support frame. The lower end of the rotating shaft 301 extends into the intermediate cylinder 4 and is equipped with a paddle mechanism. The rotating shaft 301 can be rotated by the drive motor 3, which in turn drives the paddle mechanism to work. The paddle mechanism can push water in the intermediate cylinder 4, thereby realizing the circulation of reagents in the tank body 1 and forming a circulating baffle structure.

[0032] A discharge port 103 is provided at the lower end of the tank body 1, and a vent 104 is provided at the lower end of the conical part 101 near the lower end of the tank body 1. An overflow port 105 is provided on the upper part of the outer periphery of the tank body 1. The various openings of the tank body 1 allow materials and related reagents to enter and exit, and can be opened when in use and closed when not in use.

[0033] Reference Figure 1 , Figure 2As shown, an annular filter screen 5 is provided between the intermediate cylinder 4 and the outer periphery of the conical part 101. During the cyclic reaction, the reagent can form solid particulate components, and these solid particulate components will gradually increase in size as the reaction progresses. The filter screen 5 can block the solid particles in the tank 1, confining the solid particulate components obtained from the reaction within a limited space, thereby achieving concentrated aggregation of the reaction product.

[0034] An annular cylinder 2 is installed inside the tank body 1. The annular cylinder 2 is fitted around the outer periphery of the intermediate cylinder 4 and is connected and supported by a fixed connecting frame. The upper part of the annular cylinder 2 is fixedly connected to the top cover 102 of the tank body 1, and the lower end of the annular cylinder 2 extends to the upper side of the filter screen 5, forming a gap.

[0035] Specifically, the vertical baffled reactor in this embodiment can achieve decalcification treatment of wastewater. With appropriate reaction reagents, calcium ions in the wastewater can react and, with the cyclic reaction, the calcium ions in the wastewater will react to form precipitates.

[0036] Drive motor 3 operates, which drives shaft 301 to rotate, and then drives blade mechanism to operate through shaft 301.

[0037] When the drive motor 3 rotates in the forward direction, the paddle mechanism will drive the reagent in the intermediate cylinder 4 downward, and the reagent inside and outside the intermediate cylinder 4 will circulate. The reagent in the tank 1 will enter from the upper end of the intermediate cylinder 4 and then exit from the lower end of the intermediate cylinder 4. In conjunction with the circulating filtration of the reagent by the filter screen 5, the solid precipitate particles in the reagent will be centrally collected in the space below the filter screen 5, forming a reaction precipitate accumulation below the filter screen 5. Then, the precipitate can be discharged through the discharge port 103 at the lower end of the tank 1.

[0038] As the reaction continues, the calcium ion concentration of the reagent in tank 1 will gradually decrease, while the sediment on the surface of filter screen 5, especially on the lower side, will gradually increase, potentially clogging the surface of filter screen 5. At this point, the drive motor 3 rotates in reverse, and the paddle mechanism will drive the reagent in the intermediate cylinder 4 upwards, achieving a circulating flow of reagent between the inside and outside of the intermediate cylinder 4. The reagent in tank 1 will be output upwards within the intermediate cylinder 4, while the reagent on the outer periphery of the intermediate cylinder 4 will move downwards. The downward-flowing reagent will pass through filter screen 5 from top to bottom, re-cleaning the surface of filter screen 5 and flushing off the sediment that has accumulated on the lower side of filter screen 5, thus achieving backwashing and cleaning of filter screen 5. Furthermore, the reverse circulation rinsing improves the backwashing and cleaning effect of filter screen 5.

[0039] Furthermore, the filter screen 5 has a two-layer structure, namely filter screen one 501 and filter screen two 502. Filter screen one 501 is located above filter screen two 502, and filter screen one 501, filter screen two 502, tank body 1, and intermediate cylinder 4 form an annular cavity 503.

[0040] The intermediate cylinder 4 has several through holes 401 at positions corresponding to the annular cavity 5030. A lifting cylinder 6 is fitted inside the intermediate cylinder 4. The lifting cylinder 6 extends at least partially into the intermediate cylinder 4 from its lower end, and the intermediate cylinder 4 and the lifting cylinder 6 are slidably sealed by a sealing guide. The outer circumference of the lifting cylinder 6 has several through holes 601. The positions of the first through holes 401 and the second through holes 601 correspond to each other. When they are opposite each other, they can communicate with each other. When they are misaligned, the through holes can be closed. A blocking part 602 is provided on the lower inner circumference of the lifting cylinder 6, which can basically close the lower part of the lifting cylinder 6.

[0041] When the lifting cylinder 6 descends, the outer wall of the lifting cylinder 6 can block and seal the through hole 401, and the blocking part 602 opens the lower end of the intermediate cylinder 4. When the lifting cylinder 6 rises, the through hole 601 of the lifting cylinder 6 is opposite to the through hole 401, and the blocking part 602 blocks the lower end of the intermediate cylinder 4.

[0042] A lifting actuator is installed at the lower part of the tank body 1. The lifting actuator includes a lifting rod 7 that can move up and down. The lifting rod 7 passes through the bottom of the tank body 1, and a seal is installed at the penetration position between the lifting rod 7 and the tank body 1. The lifting rod 7 achieves sealing through the sliding seal. The upper end of the lifting rod 7 can abut against the blocking part 602 at the lower part of the lifting cylinder 6, thereby pushing the lifting cylinder 6 to move upward. After the lifting rod 7 descends, the lifting cylinder 6 will also descend along with the lifting rod 7.

[0043] An expansion portion 603 is fixedly connected to the lower outer periphery of the lifting cylinder 6. The expansion portion 603 has a ring-shaped protrusion structure and a cone-shaped structure that gradually expands downward.

[0044] Reference Figure 1 As shown, when the lifting cylinder 6 moves upward, the outer expansion portion 603 of the outer periphery of the lifting cylinder 6 will press against and limit the lower end of the intermediate cylinder 4, thus limiting the lifting cylinder 6 at its uppermost position. Furthermore, the through hole 401 of the intermediate cylinder 4 and the through hole 601 of the lifting cylinder 6 can be opposite each other, thereby forming a channel connecting the inner and outer peripheries of the intermediate cylinder 4 and the lifting cylinder 6 to connect the intermediate cylinder 4 and the annular cavity 503.

[0045] Reference Figure 2As shown, when the lifting cylinder 6 moves downward, the outer expansion portion 603 of the outer periphery of the lifting cylinder 6 will abut against the inner wall of the conical portion 101, which can support and limit the lifting cylinder 6, thus restricting the lower end position of the lifting cylinder 6. At this time, the upper part of the lifting cylinder 6 can block the through hole 401 of the intermediate cylinder 4.

[0046] Furthermore, a vertically penetrating channel 604 is provided in the middle of the blocking part 602, and a valve device 8 is provided at the channel 604, which can be used to adjust the opening and closing of the channel 604. (Refer to...) Figure 1 As shown, the valve device 8 can open the channel 604 when the lifting cylinder 6 rises; refer to Figure 2 As shown, the valve device 8 can close the channel 604 when the lifting cylinder 6 descends.

[0047] Specifically, the blade mechanism is located on the inner circumference of the intermediate cylinder 4 and above the through hole 401. The blade mechanism includes a rotating cylinder 302 and several blades 303. The rotating cylinder 302 is sleeved on the outer circumference of the rotating shaft 301 and is fixedly connected by a bracket. The blades 303 are fixedly connected to the outer circumference of the rotating cylinder 302. A through channel is formed on the inner circumference of the rotating cylinder 302 to allow reagent flow.

[0048] The lower end of the rotating cylinder 302 extends downward, partially penetrating into the lifting cylinder 6. The rotating cylinder 302 can be linked with the valve device 8, thereby controlling the opening and closing state of the valve device 8 and enabling the lifting and lowering movements of the valve device 8 and the lifting cylinder 6 to be synchronized.

[0049] Reference Figure 3 , Figure 4 As shown, the valve device 8 includes a support plate 801, a rotating plate 802, a roller 803, a movable cylinder 804, a linkage rod 805, a sealing plug 806, and a spring 809. The support plate 801 is fixedly mounted on the upper side of the blocking part 602, and the inner circumference of the support plate 801 is opposite to the channel 604. The rotating plate 802 is mounted on the upper part of the support plate 801, and an annular groove is formed on the opposite side of the support plate 801 and the rotating plate 802. The support plate 801 and the rotating plate 802 are rotatably connected by the roller 803, which is embedded in the annular groove. The roller 803 can guide the rotation of the rotating plate 802 and bear downward loads.

[0050] A movable cylinder 804 is provided on the upper part of the rotating disk 802. The movable cylinder 804 is coaxially arranged with the rotating disk 802 and can be adjusted up and down. An annular protrusion 8010 is fixedly connected to the outer periphery of the movable cylinder 804, which can form an elastic support limit. Furthermore, a spring 809 provides elastic support between the annular protrusion 8010 and the rotating disk 802. Specifically, the lower end of the spring 809 is fixedly connected to the upper side of the rotating disk 802, and the lower side of the annular protrusion 8010 is fixedly connected to the upper end of the spring 809. The spring 809 can both limit and support the movable cylinder 804 and provide elastic support.

[0051] The upper end of the movable cylinder 804 extends upward and can partially extend into the rotating cylinder 302. During the upward movement of the movable cylinder 804, the upper part of the movable cylinder 804 extends into the rotating cylinder 302, where the annular protrusion 8010 abuts against the lower end of the rotating cylinder 302 to achieve a pressure seal. This ensures a sealed connection between the movable cylinder 804 and the rotating cylinder 302, thereby sealing the gap between them.

[0052] Furthermore, a linkage rod 805 is coaxially fixedly connected to the inner circumference of the movable cylinder 804 via a bracket. The connection between the linkage rod 805 and the movable cylinder 804 is not completely sealed, and an upper channel is still formed within the movable cylinder 804. Moreover, the linkage rod 805 extends downwards and is fixedly connected to a sealing plug 806. The sealing plug 806 and the linkage rod 805 can elastically float up and down with the movable cylinder 804, thereby enabling the switching of the sealing plug 806 and the channel 604 on and off.

[0053] Specifically, a flared opening 6041 that gradually widens is formed at the lower end of the channel 604, and a sealing plug 806 has a shape on its upper part that matches the flared opening 6041. The shape of the flared opening 6041 and the shape of the sealing plug 806 are adapted to each other, forming a roughly conical structure. Under the elastic action of the spring 809, the spring 809 can drive the movable cylinder 804, the linkage rod 805, and the sealing plug 806 to move upward. Through the adaptation of the sealing plug 806 with the flared opening 6041, the switching of the channel 604 on and off is realized.

[0054] This embodiment discloses a cyclic reaction process using a vertical baffled reaction device as described in the previous embodiment. During the cyclic reaction, the lifting rod 7 moves downward, and the lifting cylinder 6 moves downward under its own weight. The first through hole 401 on the outer periphery of the intermediate cylinder 4 is closed, and the second through hole 601 on the outer periphery of the lifting cylinder 6 is opened. The valve device 8 closes the channel 604 under the action of the spring 809. Then, the drive motor 3 rotates forward, and the reagent in the tank 1 enters from the upper end of the intermediate cylinder 4 and exits from the lower end of the intermediate cylinder 4, flowing outward from the second through hole 601 of the lifting cylinder 6. Then, it flows upward through the second filter screen 502 and the first filter screen 501 in sequence, and then flows back to the vicinity of the upper end of the intermediate cylinder 4, finally entering the intermediate cylinder 4, realizing the circulation of the reagent. A reaction precipitate accumulates on the lower side of the filter screen 5.

[0055] When backwashing of filter screen 501 and filter screen 502 is required, the lifting rod 7 moves upward, supporting the blocking part 602 and driving the lifting cylinder 6 upward. The outward expansion part 603 and the blocking part 602 on the outer side of the lifting cylinder 6 can basically block and seal the lower end of the intermediate cylinder 4. Then, the upper part of the movable cylinder 804 of the valve device 8 extends into the rotating cylinder 302, and the annular protrusion 8010 and the rotating cylinder 302 abut against each other to form a mutual sleeve. At the same time, the annular sealing part 807 on the lower side of the movable cylinder 804 and the annular sealing part 808 on the upper side of the rotating disk 802 press against each other to achieve mutual pressure sealing. At the same time, the sealing plug 806 will descend with the movable cylinder 804, so that the flared mouth 6041 and the movable cylinder 804 can be opened, thereby opening the channel 604. Then, the drive motor 3 rotates in the opposite direction, which can drive the rotating cylinder 302 and the blades 303 to rotate through the rotating shaft 301. This creates a downward flow between the rotating cylinder 302 and the intermediate cylinder 4, and the liquid enters the annular cavity 503 between the filter screen 1 501 and the filter screen 2 502 through the second through hole 601 and the first through hole 401. The reagent flowing outward from the annular cavity 503 can impact the filter screen 1 501 and the filter screen 2 502, thereby washing away the deposits on the surface of the filter screen and achieving backwashing and cleaning of the filter screen 5.

[0056] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
