Abstract
Description
Technical Field
[0001] The present application relates to the technical field of battery recycling, and in particular to a reaction tank. Background Art
[0002] In the process of battery recycling, the crushed battery powder needs to be subjected to an acid leaching process to obtain a lithium sulfate solution, and the obtained lithium sulfate solution is step-by-step removed from the solution to remove impurities such as copper, iron, and aluminum to obtain a pure lithium sulfate solution, thereby achieving the purpose of selectively extracting lithium from the recycled battery powder. The pure lithium sulfate solution can be used to synthesize lithium carbonate to achieve the recycling and reuse of battery materials.
[0003] During the reaction process of the acid leaching process, in order to leach and extract lithium elements, acid and hydrogen peroxide are generally added to the battery powder for reaction. After the reaction is completed, the slurry is taken out and filtered, and the content of lithium, iron, copper and other elements in the slurry is detected. After the qualified slurry is filtered, the obtained filtrate is subjected to the leaching and impurity removal process, such as the iron powder copper removal process and the iron and aluminum removal process. In the iron powder copper removal process and the iron and aluminum removal process, it is necessary to take out the slurry from the reaction tank as a sample many times during the chemical reaction, and detect the content of copper elements and the content of iron and aluminum impurities in the sample until the test results of the sample meet the requirements of the process setting. In the entire leaching and impurity removal process, it is necessary to sample the slurry and filtrate in each process many times, detect the material condition in the reaction tank, and determine whether the next step can be performed.
[0004] At present, the sampling operation of the leaching and impurity removal process usually uses a simple sampler to sample and test the liquid in the reaction tank. However, most common samplers are devices with a long rod directly connected to a sampling bucket at the end. The size of the sampling bucket is limited, and it is not convenient to enter and exit the sampling port. Moreover, during the sampling process, the sampling bucket needs to be immersed in the slurry, and it is easy for the sampling bucket to be attached with various impurities, affecting the test results. At the same time, the sampling operation of the leaching and impurity removal process usually requires first taking the slurry in the reaction tank, then filtering the slurry, and then taking the filtrate for testing. The entire sampling and testing operation is relatively cumbersome. Utility Model Content
[0005] The purpose of this application is to provide a reaction tank that can realize battery slurry filtration sampling.
[0006] In order to achieve the above purpose, this application adopts the following technical solutions:
[0007] A reaction tank comprises a tank body, a liquid inlet component and a sampling component, wherein:
[0008] The sampling assembly comprises a sampling cavity isolated from the interior of the tank body, wherein a sampling member capable of entering and exiting the sampling cavity is arranged in the sampling cavity;
[0009] The liquid inlet assembly includes a liquid inlet cavity and a liquid inlet cover that can cover the liquid inlet cavity; when the liquid inlet cover is covered on the liquid inlet cavity, the liquid inlet cavity is isolated from the interior of the tank body; when the liquid inlet cover is separated from the liquid inlet cavity, the liquid inlet cavity is connected with the interior of the tank body; a liquid outlet connected with the sampling cavity is arranged in the liquid inlet cavity, and a filter is arranged in the liquid outlet.
[0010] According to the liquid level height to be sampled, the liquid inlet component can be set at the bottom, middle or other height positions of the tank body, and the sampling range of the tank body can be set according to the process requirements. When the reaction tank needs to be sampled, the sampling component is placed in the sampling cavity, and the sampling component is located below the liquid outlet to ensure that the sampled filtrate enters the sampling component. Open the liquid inlet cover, the slurry in the tank body enters the liquid inlet cavity, and after being filtered by the filter element at the liquid outlet, it flows into the sampling cavity and enters the sampling component. After the sample volume taken by the sampling component reaches the requirement, close the liquid inlet cover to isolate the liquid inlet cavity from the inside of the tank body, and the slurry no longer enters the sampling cavity, and the sampling component can be taken out. Because the sampled slurry has been filtered by the filter element at the liquid outlet, the sampled slurry can be sent directly for testing.
[0011] The reaction tank is provided with a liquid inlet chamber and a sampling chamber, so that the sampling component does not need to be immersed in the slurry inside the tank body when performing the sampling operation, which effectively avoids the situation where the inspection result is affected by impurities attached to the sampling component. Moreover, the position of the liquid inlet chamber is arranged in the reaction tank, so that the operator can determine the sampling area at that time, making the sampling operation more stable. By controlling the movement of the liquid inlet cover, the sampling component can obtain the required slurry volume. The operator does not need to repeatedly measure and observe, and can complete the quantitative sampling operation in the specified area of the tank body.
[0012] In some embodiments, a liquid outlet tube is provided on the liquid inlet cavity, and the liquid outlet tube extends into the sampling cavity through the liquid outlet port and protrudes from the inner wall of the sampling cavity.
[0013] When the sampled slurry flows into the sampling cavity through the liquid outlet tube, since the liquid outlet tube protrudes from the inner wall of the sampling cavity, the slurry will fall into the sampling component instead of flowing to the inner wall of the sampling cavity. This not only makes sampling more convenient, but also prevents the slurry from contaminating the sampling cavity by falling directly into the sampling component.
[0014] In some embodiments, a liquid inlet tank and a sampling tank are provided on the periphery of the tank body. The liquid inlet tank is connected to the interior of the tank body, and the sampling tank is isolated from the interior of the tank body. The liquid inlet assembly is arranged in the liquid inlet tank and protrudes from the outer edge of the tank body; the sampling cavity is formed in the sampling tank and protrudes from the outer edge of the tank body.
[0015] By arranging the liquid inlet tank and the sampling tank, the liquid inlet assembly and the sampling cavity protrude from the outer edge of the tank body, reducing the space occupied inside the tank body, making it convenient to install the stirring structure inside the tank body and avoiding affecting the stirring operation inside the tank body.
[0016] In some embodiments, the liquid inlet tank is a columnar structure, the liquid inlet cover matches the inner wall of the liquid inlet tank, and the liquid inlet cover is connected to a traction member extending to the outside of the liquid inlet tank.
[0017] The operator can conveniently extract or close the liquid inlet cap by using the traction piece. Under the guidance of the liquid inlet tank structure, the operator does not need to observe and aim when closing the liquid inlet cap, and the sampling operation is simpler and more convenient.
[0018] In some embodiments, a retractable sampling port is disposed in the sampling member; when the sampling member is located below the liquid outlet, the sampling port opens and fits against the inner wall of the sampling cavity.
[0019] The sampling port has a telescopic function, which allows the sampling member entering the sampling cavity to fit the inner wall of the sampling cavity by opening the sampling port during sampling operations, thereby ensuring that the slurry flowing out of the liquid outlet or the slurry flowing out through the liquid outlet pipe can all fall into the sampling member. Moreover, through the telescopic design of the sampling port, when the operator performs slurry sampling, he only needs to place the sampling member under the liquid outlet or the liquid outlet pipe and open the sampling port until it fits the inner wall of the sampling cavity. The operator does not need to repeatedly observe and aim at the relative position of the sampling port and the sampling member, and the sampling operation will be simpler and more convenient.
[0020] In some embodiments, the sampling component includes a sampling barrel, a fixed rod, and a telescopic part, wherein the fixed rod is connected to the sampling barrel, and the sampling barrel is circumferentially provided with an elastically deformable side wall, which is surrounded by the fixed rod to form a sampling port; the telescopic part is arranged on the fixed rod, and the telescopic part moves relative to the fixed rod and applies a force to the side wall to expand toward the outside of the sampling barrel, so that the sampling port expands toward the outside of the sampling barrel, thereby achieving the sampling port and the inner wall of the sampling cavity fitting together.
[0021] By utilizing the elastic changes of the side wall itself, the sampling port can normally pass through the inside of the sampling cavity, or pass between the liquid outlet pipe and the sampling cavity in normal state, so that the operator can easily pull the sampling member in the sampling cavity. When the sampling member is located below the liquid outlet, the telescopic member is used to provide the side wall with a force to expand toward the outside of the sampling barrel, so that the sampling port expands and fits with the inner wall of the sampling cavity. The operation of changing the shape of the sampling member is relatively simple, which is conducive to simplifying the sampling operation.
[0022] In some embodiments, the telescopic member includes a movable sleeve and a connecting rod, wherein the movable sleeve is sleeved on the fixed rod and can reciprocate relative to the fixed rod; the connecting rod is arranged between the movable sleeve and the side wall, and the connecting rod is rotatably connected to the movable sleeve and the side wall.
[0023] As the movable sleeve moves back and forth along the fixed rod, the connecting rod rotates relative to the movable sleeve and the side wall, thereby repeatedly switching between the extended state and the retracted state. When the connecting rod is in the extended state, the connecting rod is at the same height as the connecting position of the movable sleeve and the side wall, and the connecting rod's own length is equal to the distance between the movable sleeve and the side wall, so that the connecting rod opens the side wall of the sampling barrel and opens the sampling port. When the connecting rod is in the retracted state, the connecting rod is at different heights as the connecting position of the movable sleeve and the side wall, and the distance between the movable sleeve and the side wall is less than the connecting rod's own length. The side wall of the sampling barrel contracts under the action of its own elasticity, causing the sampling port to retract.
[0024] In some embodiments, a plurality of reinforcing blocks are disposed on the side wall of the sampling barrel, and the reinforcing blocks are arranged along the sampling port toward the bottom of the sampling barrel, and a connecting rod is connected between the reinforcing blocks and the movable sleeve.
[0025] In some embodiments, there are multiple connecting rods, and the multiple connecting rods are arranged along the circumference of the movable sleeve.
[0026] The reinforcement block can provide sufficient structural strength for the side wall of the sampling barrel. When the sampling barrel is in an expanded state, the circumferentially arranged connecting rods and reinforcement blocks can make the side wall of the sampling barrel bear the expansion force more evenly, and the structure of the sampling barrel is more stable.
[0027] In some embodiments, there are multiple liquid inlet cavities, which are arranged along the circumference of the tank body to facilitate communication between the liquid inlet cavities and the sampling cavity, and the liquid outlets of the multiple liquid inlet cavities are staggered along the height direction of the tank body.
[0028] By arranging the positions of the liquid inlet cavities, the liquid outlets of the multiple liquid inlet cavities are staggered along the height direction of the tank body, so that the multiple liquid inlet cavities are respectively located at different heights of the tank body. When the operator needs to extract slurry from the bottom, middle or other height positions of the tank body, he only needs to lift the liquid inlet cover of the corresponding liquid inlet cavity to allow the slurry at the required height position to enter the liquid inlet cavity at the corresponding height position, thereby completing the sampling operation of the designated area, and the sampling operation is simpler and more convenient.
[0029] Compared with the prior art, the reaction tank implemented in this application has the following beneficial effects:
[0030] (1) The reaction tank is provided with a liquid inlet cavity and a sampling cavity, so that the sampling member does not need to be immersed in the slurry inside the tank body when performing the sampling operation, which effectively avoids the situation where the inspection result is affected by impurities attached to the sampling member;
[0031] (2) The reactor can be arranged so that the operator can determine the sampling area at the time by arranging the position of the liquid inlet cavity, making the sampling operation more stable. The operator can complete the sampling operation of the designated area without repeated measurement and observation;
[0032] (3) The reaction tank is provided with a liquid inlet tank and a sampling tank so that the liquid inlet assembly and the sampling cavity protrude from the outer edge of the tank body, thereby reducing the space occupied inside the tank body and facilitating the installation of a stirring structure inside the tank body to avoid affecting the stirring operation inside the tank body.

[0046] Example 1
[0047] like Figure 1-4 As shown, a reaction tank preferably implemented in Example 1 of the present application includes a tank body 1, and a liquid inlet tank 2 and a sampling tank 3 are arranged on the periphery of the tank body 1. The number of liquid inlet tanks 2 is two, namely a first liquid inlet tank 20 and a second liquid inlet tank 21. The first liquid inlet tank 20 and the second liquid inlet tank 21 are arranged on both sides of the sampling tank 3 along the circumference of the tank body 1; wherein,
[0048] The first liquid inlet tank 20 and the second liquid inlet tank 21 are both columnar structures, and the first liquid inlet tank 20 and the second liquid inlet tank 21 are connected to the interior of the tank body 1 along the height direction of the tank body 1. The first liquid inlet tank 20 and the second liquid inlet tank 21 are both provided with a liquid inlet component 4, and the liquid inlet component 4 protrudes from the outer edge of the tank body 1;
[0049] The sampling tank 3 is a columnar structure, and the sampling tank 3 is isolated from the interior of the tank body 1. The top of the sampling tank 3 is open, and a sampling cavity 50 is formed inside the sampling tank 3. The sampling cavity 50 protrudes from the outer edge of the tank body 1 and is isolated from the interior of the tank body 1.
[0050] The liquid inlet assembly 4 and the sampling chamber 50 protrude from the outer edge of the tank body 1, which can reduce the space occupied by the liquid inlet assembly 4 and the sampling chamber 50 inside the tank body 1, and will not affect the internal installation of the stirring structure of the tank body 1, so that the reaction tank structure can be used in the existing reaction tank. By making local modifications on the basis of the existing reaction tank, the technical application of the reaction tank can be realized, and the application investment of the reaction tank can be reduced.
[0051] like Figure 3 , 4 As shown, in this embodiment 1, the liquid inlet assembly 4 disposed in the first liquid inlet tank 20 and the liquid inlet assembly 4 disposed in the second liquid inlet tank 21 have the same structure. The liquid inlet assembly 4 includes a liquid inlet cylinder 40 isolated from the inside of the tank body 1, the top of the liquid inlet cylinder 40 is open, a liquid inlet cavity 41 is formed inside the liquid inlet cylinder 40, and a liquid inlet cover 42 covers the top opening of the liquid inlet cylinder 40. A liquid outlet 44 communicating with the sampling cavity 50 is disposed on the side wall of the liquid inlet cylinder 40, and a filter 46 is disposed in the liquid outlet 44.
[0052] The liquid inlet cover 42 matches the inner wall of the liquid inlet tank 2, and is connected to a traction member 43 extending to the outside of the liquid inlet tank 2. By pulling the traction member 43, the liquid inlet cover 42 can cover or separate from the top opening of the liquid inlet cylinder 40. When the liquid inlet cover 42 covers the top opening of the liquid inlet cylinder 40, the liquid inlet cavity 41 is isolated from the interior of the tank body 1; when the liquid inlet cover 42 is separated from the top opening of the liquid inlet cylinder 40, the liquid inlet cavity 41 is connected to the interior of the tank body 1.
[0053] like Figure 2 As shown, in this embodiment 1, the liquid inlet assembly 4 disposed in the first liquid inlet tank 20 is arranged at the bottom of the tank body 1, and the liquid inlet assembly 4 disposed in the second liquid inlet tank 21 is arranged in the middle of the tank body 1, so that the liquid outlets 44 of the liquid inlet cavities 41 of the two are at different heights of the tank body 1, and are arranged in a staggered manner along the height direction of the tank body 1. When it is necessary to extract the slurry at the bottom or the middle of the tank body, it is only necessary to pull up the liquid inlet assembly 4 in the first liquid inlet tank 20 or the liquid inlet cover 42 of the liquid inlet assembly 4 in the second liquid inlet tank 21, so that the slurry at the corresponding height position enters the corresponding liquid inlet cavity 41.
[0054] like Figure 1 , 3As shown, the sampling assembly 5 includes a sampling cavity 50 formed inside the sampling tank 3, and a sampling component 51, wherein the sampling component 51 includes a sampling barrel 510 and a fixing rod 511 connected to the sampling barrel 510, and a sampling port 5101 is provided on the sampling barrel 510, and the caliber of the sampling port 5101 should be less than or equal to the inner diameter of the sampling cavity 50, so that the sampling barrel 510 can enter and exit the sampling cavity 50.
[0055] The sampling process of the reaction tank of this embodiment 1 is as follows:
[0056] Open the sampling tank 3 and place the sampling member 51 into the sampling cavity 50. According to the liquid level required for sampling, move the sampling barrel 510 downward to the lower side of the liquid outlet 44 corresponding to the first liquid inlet tank 20 or the second liquid inlet tank 21, and make the sampling port 5101 fit the inner wall of the sampling cavity 50. Pull up the traction member 43 corresponding to the liquid inlet tank 2, open the liquid inlet cover 42, and the slurry in the tank body 1 enters the liquid inlet cavity 41 of the first liquid inlet tank 20 or the second liquid inlet tank 21, and after being filtered by the filter member 46 of the liquid outlet 44, it flows into the sampling cavity 50 and falls into the interior of the sampling barrel 510. When the sample volume taken by the sampling barrel 510 reaches the required amount, close the liquid inlet cover 42 to isolate the liquid inlet cavity 41 from the interior of the tank body 1, and the slurry no longer enters the sampling cavity 50, thus completing the sampling operation of collecting a quantitative amount of slurry in the designated area of the tank body 1. The sampling barrel 510 is pulled up by the fixing rod 511 to remove the sampling member 51. Since the sampled slurry has been filtered by the filter element 46 of the liquid outlet 44, the sampled slurry can be directly sent for detection.
[0057] Compared with the existing sampling operation, the reaction tank sampling process of the present embodiment 1 can enable the sampling component 5 to collect a certain amount of slurry by controlling the action of the liquid inlet cover 42. The operator does not need to sample by hand, and the slurry sampling process is more accurate. Moreover, the slurry is collected through the liquid inlet chamber 41 and the sampling chamber 50, and the sampling barrel 510 does not need to be immersed in the slurry, which effectively avoids the situation where the inspection result is affected by impurities attached to the sampling barrel 510.
[0058] Example 2
[0059] like Figure 5 , 6 As shown, the difference between this embodiment 2 and embodiment 1 is that in this embodiment 2, a liquid outlet pipe 45 is provided on the side wall of the liquid inlet cylinder 40, and the liquid outlet pipe 45 extends into the sampling cavity 50 through the liquid outlet port 44 and protrudes from the inner wall of the sampling cavity 50. Since the liquid outlet pipe 45 protrudes from the inner wall of the sampling cavity 50, it will occupy a certain internal space of the sampling cavity 50. At this time, the sampling barrel 510 and the sampling port 5101 should ensure that the distance between the liquid outlet pipe 45 and the inner wall of the sampling cavity 50 can be passed normally.
[0060] The sampling process of the reaction tank of this embodiment 2 is as follows:
[0061] Open the sampling tank 3 and place the sampling member 51 into the sampling cavity 50. According to the liquid level required for sampling, the sampling barrel 510 is moved down to the lower part of the liquid outlet pipe 45 corresponding to the first liquid inlet tank 20 or the second liquid inlet tank 21, and the mouth of the liquid outlet pipe 45 is located in the sampling port 5101. At this time, the sampling barrel 510 or the sampling port 5101 does not need to be attached to the inner wall of the sampling cavity 50, and the sampling operation is more convenient.
[0062] The traction member 43 of the corresponding liquid inlet tank 2 is pulled up, and the liquid inlet cover 42 is opened, and the slurry in the tank body 1 enters the liquid inlet cavity 41 of the first liquid inlet tank 20 or the second liquid inlet tank 21, and after being filtered by the filter member 46 of the liquid outlet 44, flows along the liquid outlet pipe 45 to the sampling cavity 50. Since the liquid outlet pipe 45 protrudes from the inner wall of the sampling cavity 50, the slurry entering the sampling cavity 50 will fall into the sampling barrel 510, and will not flow to the inner wall of the sampling cavity 50, thereby ensuring the cleanliness of the interior of the sampling cavity 50.
[0063] When the sample volume taken by the sampling barrel 510 reaches the required amount, the liquid inlet cover 42 is closed to isolate the liquid inlet cavity 41 from the interior of the tank body 1, and the slurry no longer enters the sampling cavity 50, thus completing the sampling operation of collecting a certain amount of slurry in the designated area of the tank body 1. The sampling barrel 510 is lifted by the fixing rod 511 to remove the sampling barrel 510.
[0064] Example 3
[0065] like Figure 7 , 8 As shown, the difference between this embodiment 3 and embodiments 1 and 2 is that in this embodiment 3, an elastically deformable side wall 5100 is circumferentially provided on the sampling barrel 510, and the side wall 5100 is enclosed around the fixing rod 511 to form a retractable sampling port 5101, and a plurality of reinforcing blocks 512 are arranged on the side wall 5100 of the sampling barrel and arranged along the sampling port 5101 toward the bottom of the sampling barrel 510.
[0066] The fixed rod 511 is provided with a telescopic member 513. The telescopic member 513 includes a movable sleeve 5130 that can move relative to the fixed rod 511, the movable sleeve 5130 is sleeved on the fixed rod 511, and a plurality of connecting rods 5131 are provided between the movable sleeve 5130 and the side wall 5100, and the plurality of connecting rods 5131 are arranged along the circumference of the movable sleeve 5130, and each connecting rod 5131 is rotatably connected to the movable sleeve 5130 and the reinforcing block 512 respectively.
[0067] When the movable sleeve 5130 moves relative to the fixed rod 511 , the connecting rod 5131 rotates relative to the movable sleeve 5130 and the reinforcing block 512 on the side wall 5100 , thereby repeatedly switching between the extended state and the retracted state.
[0068] like Figure 7As shown, when the connecting rod 5131 is in the extended state, the connecting rod 5131 is at the same height as the connection positions of the movable sleeve 5130 and the reinforcing block 512, and the length of the connecting rod 5131 is equal to the distance between the movable sleeve 5130 and the reinforcing block 512, so that the connecting rod 5131 can open the side wall 5100 of the sampling barrel 510. When the connecting rod 5131 switches to the extended state, the connecting rod 5131 will exert a force on the side wall 5100 to expand toward the outside of the sampling barrel 510, so that the side wall 5100 expands toward the outside of the sampling barrel 510, and the sampling port 5101 opens, so that the sampling barrel 510 as a whole presents a frustum shape with a large upper part and a small lower part.
[0069] like Figure 8 As shown, when the connecting rod is in the retracted state, the connection positions of the connecting rod 5131, the movable sleeve 5130 and the side wall 5100 are at unequal heights, and the distance between the movable sleeve 5130 and the side wall 5100 is smaller than the length of the connecting rod 5131. The side wall 5100 of the sampling barrel 510 contracts under the action of its own elasticity, so that the sampling port 5101 is retracted.
[0070] like Figure 8 As shown, a locking structure 514, such as an externally connected bolt structure, may be provided on the movable sleeve 5130 to lock the position of the movable sleeve 5130 so that the connecting rod 5131 remains in an extended state when the sampling barrel 510 is sampling.
[0071] The sampling process of the reaction tank of this embodiment 3 is as follows:
[0072] The movable sleeve 5130 is pulled, so that the movable sleeve 5130 drives the connecting rod 5131 to move away from the bottom of the sampling barrel 510, and the connecting rod 5131 no longer supports the side wall 5100 of the sampling barrel 510. The side wall 5100 of the sampling barrel 510 contracts under the action of its own elasticity, so that the sampling port 5101 is folded. The folded sampling port 5101 can ensure that the sampling barrel 510 passes through the gap between the liquid outlet pipe 45 and the sampling cavity 50, or the sampling barrel 510 can smoothly enter and exit the sampling cavity 50 without the liquid outlet pipe 45.
[0073] Open the sampling tank 3 and place the sampling member 51 into the sampling cavity 50. According to the liquid level required for sampling, move the sampling tube downward to below the liquid outlet 44 or the liquid outlet pipe 45 corresponding to the first liquid inlet tank 20 or the second liquid inlet tank 21.
[0074] The movable sleeve 5130 is pushed, so that the movable sleeve 5130 drives the connecting rod 5131 to move toward the bottom of the sampling barrel 510, and the connecting rod 5131 supports the side wall 5100 of the sampling barrel 510 outward, so that the side wall 5100 of the sampling barrel 510 is opened and closely connected with the inner wall of the sampling chamber 50. The position of the movable sleeve 5130 is locked by the locking structure 514, so that the connecting rod 5131 remains in the extended state.
[0075] The traction member 43 of the corresponding liquid inlet tank 2 is pulled up, and the liquid inlet cover 42 is opened, so that the slurry in the tank body 1 enters the liquid inlet cavity 41 of the first liquid inlet tank 20 or the second liquid inlet tank 21, and after being filtered by the filter member 46 of the liquid outlet 44, flows to the sampling cavity 50 and falls into the sampling barrel 510. When the sample volume taken by the sampling barrel 510 reaches the required amount, the liquid inlet cover 42 is closed to isolate the liquid inlet cavity 41 from the inside of the tank body 1, and the slurry no longer enters the sampling cavity 50, that is, the sampling operation of collecting a certain amount of slurry in the designated area of the tank body 1 is completed.
[0076] Then, the locking structure 514 is released, and the connecting rod 5131 is switched to the retracted state by pulling the movable sleeve 5130, so that the sampling port 5101 is retracted. The sampling barrel 510 is lifted by the fixing rod 511 to take out the sampling barrel 510.
[0077] In the present embodiment 3, by making the sampling port 5101 have the telescopic function, the sampling barrel 510 that enters the sampling cavity 50 can be made to fit the inner wall of the sampling cavity 50 by opening the sampling port 5101 during the sampling operation, thereby ensuring that the slurry flowing out of the liquid outlet 44 or the slurry flowing out through the liquid outlet pipe 45 can all fall into the sampling barrel 510. Moreover, through the telescopic design of the sampling port 5101, when the operator performs slurry sampling, he only needs to place the sampling barrel 510 under the liquid outlet 44 or the liquid outlet pipe 45 and open the sampling port 5101 until it fits the inner wall of the sampling cavity 50. The operator does not need to repeatedly observe and aim at the relative position of the sampling port 5101 and the sampling barrel 510, and the sampling operation will be simpler and more convenient.
[0078] In summary, the embodiment of the present application provides a reaction tank, which, through the arrangement of the liquid inlet chamber 41 and the sampling chamber 50, does not need to immerse the sampling member 51 in the slurry inside the tank body 1 when performing the sampling operation, effectively avoiding the situation where the inspection result is affected by impurities attached to the sampling member 51. Moreover, the reaction tank can enable the operator to determine the area to be sampled at the time by arranging the position of the liquid inlet chamber 41, making the sampling operation more stable, and the operator can complete the quantitative sampling operation of the specified area without repeated measurement and observation. In addition, by making the sampling port 5101 have the function of extension and retraction, the slurry flowing out from the liquid outlet 44 or the slurry flowing out through the liquid outlet pipe 45 can all fall into the sampling bucket 510. When the operator samples the slurry, he only needs to place the sampling bucket 510 under the liquid outlet 44 or the liquid outlet pipe 45, and open the sampling port 5101 until it fits with the inner wall of the sampling cavity 50. There is no need to repeatedly observe and aim at the relative position of the sampling port 5101 and the sampling bucket 510, and the sampling operation will be simpler and more convenient.
[0079] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
