Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0031] The terms "first", "second" and "third" (if any) in the specification and claims of this application and the above drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0032] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or display comprising a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or display.

[0033] In the prior art, the liquid seal tank of the tail gas leaching tower is provided with an air inlet, an air outlet, a water inlet, an overflow port and a drain port. The water inlet is in the middle and upper part of the liquid seal tank. The overflow port is in the middle of the liquid seal tank, which mainly plays the role of controlling the liquid level of the liquid seal tank. The drain port is at the bottom of the liquid seal tank, which is mainly used to remove the sediment in the liquid seal tank. However, the existing leaching tower still needs to be released through the drain port after long-term use, so it is necessary to stop the operation, which affects the production process and reduces the practicality of the leaching tower.

[0034] After repeated thinking and verification, the inventor found that if a blocking mechanism is set in the liquid seal tank, the blocking mechanism divides the inside of the liquid seal tank into a first chamber and a second chamber, and the blocking mechanism is driven by the driving mechanism to move to control the connection state between the first chamber and the second chamber. The liquid seal tank is connected to the drain pipe, the water pipe and the air inlet pipe respectively. The drain pipe is connected to the second chamber, the air inlet pipe is connected to the first chamber, and the water pipe is used to inject liquid into the second chamber. When it is necessary to use the drain port on the liquid seal tank for release, the driving mechanism drives the blocking mechanism to move, and the blocking mechanism separates the first chamber from the second chamber, opens the water pipe and the drain pipe, and the reaction continues in the second chamber without affecting the normal operation of the elution tower. The sediment in the second chamber flows out along the drain pipe and is dispersed by the water impact of the water pipe, avoiding blockage and achieving the effect of cleaning and discharge. While thoroughly cleaning the liquid seal tank, it does not affect the reaction, ensuring the production process, and improving the use effect and practicality of the device.

[0035] In view of this, the inventor has designed a liquid seal tank anti-blocking device, which divides the interior of the liquid seal tank by a blocking mechanism, and the liquid seal tank is respectively connected to the drain pipe, the water supply pipe and the air inlet pipe, and a switch valve is installed on the drain pipe. When the drain port on the liquid seal tank needs to be used for release, the driving mechanism drives the blocking mechanism to move, and the blocking mechanism isolates the interior of the liquid seal tank. The reaction continues on the side of the blocking mechanism away from the drain pipe inside the liquid seal tank. The sediment on the side of the blocking mechanism toward the drain pipe inside the liquid seal tank flows out along the drain pipe and is dispersed by the water impact of the water supply pipe, avoiding blockage while achieving the effect of cleaning and discharge, and thoroughly cleaning the liquid seal tank without affecting the reaction.

[0036] The technical solution of the liquid seal groove anti-blocking device provided in the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0037] Reference Figure 1 As shown, the anti-blocking device for the liquid sealing groove provided in the embodiment of the present application includes a liquid sealing tank 100, a driving mechanism 200 and a blocking mechanism 300. The liquid sealing tank 100 has a accommodating chamber 170, and a drain pipe 110 is provided at one end of the liquid sealing tank 100, and a switch valve 120 is installed on the drain pipe 110. The liquid sealing tank 100 is connected to a water supply pipe 130, and an air intake pipe 140 is provided at one end of the liquid sealing tank 100 away from the drain pipe 110. The blocking mechanism 300 is installed in the middle of the liquid sealing tank 100, and the blocking mechanism 300 divides the accommodating chamber 170 into a first chamber and a second chamber, the drain pipe 110 is connected to the first chamber, the air intake pipe 140 is connected to the second chamber, and the water supply pipe 130 is configured to inject liquid into the second chamber. The driving mechanism 200 is installed on the liquid sealing tank 100 . The driving mechanism 200 is connected to the blocking mechanism 300 . The driving mechanism 200 is configured to drive the blocking mechanism 300 to move so as to control the communication state between the first chamber and the second chamber.

[0038] The drain pipe 110 can be installed at the bottom of the liquid sealing tank 100, and the connection state of the drain pipe 110 can be controlled by controlling the switch valve 120 on the drain pipe 110. It can be understood that the water supply pipe 130 can inject fresh water into the liquid sealing tank 100 to achieve the liquid sealing effect. The air inlet pipe 140 can be set at the top of the liquid sealing tank 100, and the elution gas can enter the interior of the liquid sealing tank 100 through the air inlet pipe 140.

[0039] Illustratively, the first chamber is located below the second chamber. When the switch valve 120 on the drain pipe 110 is opened, water and sediment in the first chamber can be discharged from the liquid sealing tank 100 via the drain pipe 110 .

[0040] It is worth mentioning that the connection state between the first chamber and the second chamber can be changed by adjusting the blocking mechanism 300 between the first chamber and the second chamber. Specifically, the staff can control the driving mechanism 200 to drive the blocking mechanism 300 to move so that the first chamber and the second chamber are connected to each other, or the first chamber and the second chamber are sealed and isolated. When the first chamber and the second chamber are sealed and isolated, the state of the first chamber will not affect the reaction in the second chamber.

[0041] The anti-blocking device for the liquid seal tank provided in this embodiment is in a closed state during use. Fresh water can be injected into the liquid seal tank 100 through the water supply pipe 130 to achieve the effect of liquid sealing. The elution gas can enter the interior of the accommodating chamber 170 through the air inlet pipe 140. When the drain port needs to be used for release, the water supply pipe 130 can be closed first to prevent water from flowing back. The driving mechanism 200 drives the blocking mechanism 300 to move. The blocking mechanism 300 separates the first chamber from the second chamber, and the first chamber and the second chamber are sealed and isolated. The reaction in the second chamber continues without affecting the normal operation of the elution tower. The switch valve 120 on the drain pipe 110 is opened, and the water supply pipe 130 is opened. The sediment in the second chamber flows out along the drain pipe 110 and is dispersed by the water impact of the water supply pipe 130, avoiding blockage and achieving the effect of cleaning and discharge. While the liquid seal tank 100 is thoroughly cleaned, the reaction is not affected, the production process is guaranteed, and the use effect and practicality of the device are improved.

[0042] In one embodiment, Figure 1-Figure 3 As shown, the blocking mechanism 300 includes a baffle plate 310, a connecting plate 320 and a rotating rod 330. The baffle plate 310 is fixedly connected to the liquid sealing tank 100, a connecting portion is provided on the baffle plate 310, and the connecting plate 320 is rotatably mounted on the baffle plate 310. One end of the rotating rod 330 is connected to the connecting plate 320, and the other end of the rotating rod 330 is connected to the driving mechanism 200.

[0043] For example, the baffle 310 can be fixed to the liquid sealing tank 100 by welding, bonding or threaded connection, etc., which is not limited here. When the connecting plate 320 rotates relative to the baffle 310, the connecting portion on the baffle 310 can be exposed or blocked. When the connecting portion on the baffle 310 is exposed, the first chamber and the second chamber are connected to each other; when the connecting portion on the baffle 310 is blocked, the first chamber and the second chamber are sealed and isolated.

[0044] Schematically, the rotating rod 330 is coaxially arranged with the liquid sealing tank 100. When the driving mechanism 200 drives the rotating rod 330 to rotate, the rotating rod 330 can drive the connecting plate 320 to rotate coaxially. The rotating rod 330 can be fixed to the connecting plate 320 by threaded connection or welding, etc., which is not limited here.

[0045] In this structure, the driving mechanism 200 can control the blocking mechanism 300 by driving the rotating rod 330 to rotate, so as to control the communication state between the first chamber and the second chamber.

[0046] In a specific embodiment, Figure 1-Figure 3 As shown, the connecting portion is formed as a notch 311 opened on the baffle plate 310. An inner groove 312 is provided in the baffle plate 310, and the connecting plate 320 is rotatably installed in the inner groove 312. A center ring 313 is installed in the center of the baffle plate 310, and a protrusion 321 is protruded from the center of the connecting plate 320, and the protrusion 321 passes through the center ring 313 and is fixedly connected to the rotating rod 330.

[0047] Schematically, the shape of the notch 311 can be a fan-shaped one, which is set through the baffle 310. The connecting plate 320 can rotate relative to the baffle 310 in the inner groove 312 of the baffle 310, and the inner groove 312 of the baffle 310 can limit the connecting plate 320 in the axial direction of the liquid sealing tank 100, ensuring that the connecting plate 320 can reliably block the notch 311 or expose the notch 311. Among them, the protrusion 321 on the connecting plate 320 can be a columnar structure, which is coaxially arranged with the connecting rod 210. By setting the center ring 313 on the baffle 310, it is ensured that the rotating rod 330 can be reliably connected to the connecting plate 320, and there will be no interference between the baffle 310 and the rotating rod 330.

[0048] In other embodiments, the end of the rotating rod 330 may also pass through the central ring 313 and be fixedly connected to the connecting plate 320 .

[0049] Figure 1-Figure 3 As shown, there are multiple notches 311, and the multiple notches 311 are arranged around the center of the baffle plate 310. The connecting plate 320 includes multiple blocking parts, and the multiple blocking parts are configured to block the multiple notches 311 one by one.

[0050] The number of the gaps 311 is non-limiting and is not limited here. For example, Figure 2 As shown, the number of the notches 311 can be two, and the two notches 311 can be respectively arranged on opposite sides of the baffle plate 310. The shape of the notches 311 can be fan-shaped, wherein each blocking portion is a sheet-like structure, and the shape and size of the blocking portion are consistent with the shape and size of the notches 311, and multiple blocking portions are arranged around the center of the connecting plate 320.

[0051] Through the above arrangement, the driving mechanism 200 drives the rotating rod 330 to rotate a small angle to block the gap 311 or expose the gap 311, so as to quickly adjust the connection state between the first chamber and the second chamber. When the first chamber and the second chamber are connected to each other, the connection area between the first chamber and the second chamber is larger.

[0052] In a specific embodiment, Figure 3 As shown, the inner diameter of the center ring 313 is consistent with the diameter of the protrusion 321 .

[0053] Through the above arrangement, when the rotating rod 330 drives the connecting plate 320 to rotate, the connecting plate 320 is limited by the central ring 313 so that the connecting plate 320 will not move in its own radial direction, making the rotation process of the connecting plate 320 more stable.

[0054] Optionally, the thickness of the connecting plate 320 is the same as the thickness of the inner groove 312 .

[0055] The present embodiment does not limit the specific thickness of the connecting plate 320 and the inner groove 312, and those skilled in the art can set it according to actual needs. It is understandable that during the rotation of the connecting plate 320, under the limiting effect of the inner groove 312, the connecting plate 320 and the rotating rod 330 will not move along the thickness direction of the connecting plate 320, further making the rotation process of the connecting plate 320 more stable, ensuring the sealing effect of the connecting plate 320 on the gap 311.

[0056] In one embodiment, Figure 1 As shown, a top plate 150 is installed inside the end of the liquid sealing tank 100 away from the drain pipe 110. The rotating rod 330 passes through the top plate 150 and is rotatably connected to the top plate 150, and the air inlet pipe 140 is arranged through the top plate 150.

[0057] Schematically, the shape and size of the top plate 150 match the liquid sealing tank 100. The top plate 150 can be installed inside the top of the liquid sealing tank 100, and it can be fixed to the liquid sealing tank 100 by threaded connection, bonding or welding, etc., which is not limited here. It can be understood that when the driving mechanism 200 drives the rotating rod 330 to rotate, the rotating rod 330 will not drive the top plate 150 to rotate.

[0058] In this structure, the top plate 150 can block the liquid sealing tank 100, and the washing gas will not overflow from the top of the liquid sealing tank 100 after entering the liquid sealing tank 100 from the air inlet pipe 140. In addition, the top plate 150 can also limit the rotating rod 330, so that the end of the rotating rod 330 away from the connecting plate 320 will not move relative to the liquid sealing tank 100 during the rotation process.

[0059] In one embodiment, Figure 1 As shown, the driving mechanism 200 includes a connecting rod 210 and a rotating driving member 220. The connecting rod 210 penetrates the side wall of the liquid sealing tank 100 and is rotatably connected to the liquid sealing tank 100, one end of the connecting rod 210 is connected to the rotating driving member 220, and the other end of the connecting rod 210 is drivingly connected to an end of the rotating rod 330 away from the connecting plate 320.

[0060] In a possible implementation, the connecting rod 210 may be rotatably connected to the side wall of the liquid sealing tank 100 via a bearing. The rotary drive member 220 may be a motor or a hydraulic motor, which is not limited here. Optionally, the end of the connecting rod 210 away from the rotating rod 330 may be fixedly connected to the output shaft of the rotary drive member 220 via a coupling.

[0061] In this structure, the staff only needs to control the rotating driving member 220 to make the connecting rod 210 drive the rotating rod 330 to rotate, thereby adjusting the connection state between the first chamber and the second chamber.

[0062] In a specific embodiment, Figure 1 As shown, a first screw head 331 is disposed at one end of the rotating rod 330 away from the connecting plate 320, and a second screw head 211 is disposed at one end of the connecting rod 210 away from the rotating driving member 220. The first screw head 331 is meshed with the second screw head 211.

[0063] Among them, the first screw head 331 and the second screw head 211 can be conical structures respectively. The first screw head 331 can be fixed to the rotating rod 330 by welding, and the second screw head 211 can be fixed to the connecting rod 210 by welding. The first screw head 331 is coaxially arranged with the rotating rod 330, and the second screw head 211 is coaxially arranged with the connecting rod 210. Figure 1 It is shown that the side wall of the first screw head 331 and the side wall of the second screw head 211 are respectively provided with toothed portions, and the toothed portions of the first screw head 331 are meshed with the toothed portions of the second screw head 211 .

[0064] In this structure, the connecting rod 210 and the rotating rod 330 are transmitted through the mutually meshing first screw head 331 and second screw head 211, which ensures the stability and accuracy of the transmission. The connecting rod 210 of the driving mechanism 200 can stably drive the rotating rod 330 to rotate.

[0065] like Figure 1As shown, the side wall of the liquid sealing tank 100 is connected with an overflow pipe 160 , the overflow pipe 160 is communicated with the second chamber, and the water supply pipe 130 is connected with the drain pipe 110 .

[0066] One end of the overflow pipe 160 is connected to the side wall of the liquid sealing tank 100, and the end of the overflow pipe 160 connected to the liquid sealing tank 100 is located on the side of the baffle 310 away from the drain pipe 110. When the first chamber is connected to the second chamber, the water in the first chamber and the second chamber can be discharged from the liquid sealing tank 100 through the overflow pipe 160. Figure 1 As shown, one end of the water supply pipe 130 connected to the drain pipe 110 is located between the liquid sealing tank 100 and the switch valve 120 , and fresh water can enter the interior of the liquid sealing tank 100 through the water supply pipe 130 and the drain pipe 110 .

[0067] In the related technology, the leaching tower reacts with water to produce silicon dioxide hydrate, which is deposited at the bottom of the liquid seal tank, which can easily cause the drain port of the liquid seal tank to be blocked. If not handled in time, the sediment will accumulate more and more, affecting the normal use of the liquid seal tank. Cleaning the drain port often requires stopping the entire leaching system, disrupting production continuity.

[0068] The liquid sealing tank anti-blocking device provided in the present embodiment can drive the rotating rod 330 to rotate through the driving mechanism 200 when sediment appears at the pipe opening connecting the drain pipe 110 and the liquid sealing tank 100, and the rotating rod 330 drives the connecting plate 320 to rotate, so that the connecting portion on the baffle plate 310 is exposed, and fresh water is injected through the water inlet pipe. Water is always flushed out at the upper end of the drain pipe 110 connected to the liquid sealing tank 100, thereby avoiding the sediment from being deposited at the pipe opening at the upper end of the drain pipe 110, and at the same time being carried out along the overflow pipe 160 connected on the left side, so that there is no sediment and no need for frequent cleaning, which meets the need for normal water addition of the liquid sealing tank 100, and prolongs the maintenance period of the entire elution system, ensures production continuity, and improves factory efficiency.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
