Background Art

[0002] During the processing of the electrode, in order to reduce the viscosity of the slurry and make it easier to evenly coat the slurry on the surface of the electrode, the slurry needs to be heated to make the adhesive or solvent therein more fluid. Usually, a high-temperature tank is set up in the electrode processing system to perform thermal processing on the slurry before coating.

[0003] In the existing high temperature tank, there are an inner tank and an outer tank, the inner tank forms a processing chamber, and a heat generating chamber is formed between the inner tank and the outer tank. An electric heating wire is installed in the heat generating chamber. The electric heating wire is energized to generate heat, and the heat generating chamber is heated to increase the temperature in the processing chamber, thereby achieving thermal processing of the slurry injected into the processing chamber. However, in the existing high temperature tank, during the processing of the slurry, the peripheral heating rate of the slurry is higher than the internal heating rate of the slurry, the overall heating uniformity of the slurry is poor, and the outer part of the slurry is easily dried and attached to the inner wall of the inner tank due to the high temperature, thereby affecting the subsequent thermal processing effect of the slurry. Therefore, it is necessary to solve such problems to improve the thermal processing effect of the slurry. Utility Model Content

After the slurry is injected into the silo, during the heating operation of the heating tank, the heating component will operate to generate heat in the heating part.

The setting of the liquid level meter, the controller and the oscillator enables the heating tank to spontaneously adjust the heating effect of its heat source, so that the heating component can heat the slurry according to the actual heating needs of the user, thereby improving the intelligence of the heating tank.

[0013] In some embodiments of the first aspect, the heating tank further comprises a second tank body, which is spaced apart and surrounds the outer periphery of the tank body portion of the first tank body, and defines a heat preservation chamber with the tank body portion of the first tank body, and the heat preservation chamber is filled with a heat preservation medium.

[0038] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application is clearly and completely described below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are only embodiments of a part of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

[0039] Unless otherwise defined, the technical or scientific terms used herein shall have the usual meaning as understood by a person of ordinary skill in the field to which this application belongs. The words "one", "an" or "the" and the like used in this application do not indicate a quantitative limitation, but are only used to indicate the presence of at least one. The words "include" or "comprise" and the like mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. The words "connect" or "connected" and the like are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0040] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] During the processing of the pole piece, the slurry required for the pole piece coating needs to be thermally processed so that the slurry after thermal processing can meet the coating requirements. Therefore, in the pole piece preparation system, a high temperature tank will be set up accordingly to provide a high temperature environment for thermal processing of the slurry. Please refer to Figure 1 In an existing high-temperature tank 2, an inner tank 21 is formed with a processing chamber 211, and is connected with a stirring component 212 to stir the slurry added to the processing chamber 211; the outer tank 22 is arranged around the inner tank 21 and a preset distance is spaced between the two to form a heat generating chamber 221, and an electric heating wire 222 is connected to the heat generating chamber 221. The electric heating wire 222 is operated to increase the temperature of the heat generating chamber 221. After the heat generating chamber 221 is heated, heat is exchanged with the processing chamber 211 to heat the slurry in the processing chamber 211. While the slurry is being heated, the stirring component 212 is turned on to allow the slurry at different locations of the processing chamber 211 to be heated.

[0042] However, in the above-mentioned high-temperature tank 2, the electric heating wire 222 is located in the heat generating chamber 221, and the heat generating chamber 221 is located outside the processing chamber 211. Therefore, the part of the slurry in the processing chamber 211 that is heated first is close to the chamber wall of the processing chamber 211. Generally, in order to ensure that the stirring component 212 can be loaded into the processing chamber 211, the head of the stirring component 212 needs to be smaller than the internal size of the processing chamber 211, so that the head of the stirring component 212 can be smoothly placed in the processing chamber 211 and can rotate and stir the materials during the subsequent heating operation; but correspondingly, due to the limitation of the size of the head of the stirring component 212, the mixing range of the stirring component 212 is limited, so the slurry close to the chamber wall of the processing chamber 211 (i.e., the inner wall of the inner tank 21) is difficult to be stirred, and this part of the slurry The slurry will lose moisture and dry out due to excessive heating, so that this part of the slurry cannot be used, resulting in a waste of slurry; in addition, this part of the slurry may adhere to the inner wall of the processing chamber 211 (i.e., the inner wall of the inner tank 21) due to drying. In this way, in the process of heat transfer from the heat generating chamber 221 to the processing chamber 211, the chamber wall of the processing chamber 211 (i.e., the inner wall of the inner tank 21) and the dried slurry layer will take away part of the heat. Therefore, in order to ensure the heating effect of the slurry, the heating wire 222 needs to do work to generate more heat, so that the power consumption of the heating wire 222 increases, that is, the power consumption of the high-temperature tank 2 increases. If the inner tank 21 is not cleaned regularly, the energy consumption of the high-temperature tank 2 will increase with the increase of usage time, thereby increasing the operating cost of the thermal processing slurry.

[0043] Please refer to Figure 2 In order to solve the above problems, the present application provides a pole piece processing system 1, which includes a slurry processing device 11 and a pole piece coating device 12. The slurry processing device 11 includes a heating tank 111, so that the slurry processing device 11 processes the slurry required by the pole piece coating device 12. Figures 3 to 8 , the heating tank 111 in this application is described in detail.

[0044] Please refer to Figure 3 , Figure 4 and Figure 5The heating tank 111 in the present application comprises a first tank body 1111, a material mixing assembly 116 and a heating assembly 117. The first tank body 1111 comprises a top plate 11111, a tank body 11112 and a bottom plate 11113, the top plate 11111, the tank body 11112 and the bottom plate 11113 surround a silo 11114, a material inlet 11111a and a mounting through hole 11111b are arranged on the top plate 11111, a material outlet 111131 is arranged on the bottom plate 11113, and the silo 11114 is connected to the outside through the material inlet 11111a and the material outlet 111131; the material mixing assembly 1111 6 includes a rotating body 1161 and a mixing portion 1162, the mixing portion 1162 is connected to the rotating body 1161 and placed in the material bin 11114; the rotating body 1161 is rotatably connected to the top plate 11111, and the rotating body 1161 is used to drive the mixing portion 1162 to rotate; the heating component 117 is provided with a heating portion 1171 and an electrical connection terminal 11711b, the heating portion 1171 is placed in the material bin 11114, and the electrical connection terminal 11711b is electrically connected to the power supply through the mounting through hole 11111b.

[0045] In the present application, the heating part 1171 of the heating component 117 is located in the silo 11114 of the first tank body 1111. When the slurry is injected into the silo 11114, during the heating operation of the heating tank 111, the heating component 117 will operate to generate heat in the heating part 1171. Since the heating part 1171 is in contact with the slurry, the heat of the heating part 1171 will be transferred to the slurry to achieve the purpose of heating the slurry. During the heating operation of the heating tank 111, the mixing component 117 The mixing portion 1162 of 16 will rotate under the drive of the rotating body 1161 to stir the slurry in the silo 11114, so that the slurry in each spatial position in the silo 11114 can move and touch the heating portion 1171 of the heating component 117. In this way, the slurry in the silo 11114 can be evenly heated as a whole, reducing the situation where the slurry is locally dried out due to local overheating, thereby improving the heating effect of the heating tank 111 on the slurry.

[0046] Specifically, during the heating process of the slurry, the heating part 1171 is the heat source of the heating tank 111. Since the heating part 1171 is located in the silo 11114, the heat generated by the heating part 1171 can be directly transferred to the contact part of the slurry. During the heating process of the slurry, the mixing part 1162 rotates to drive the slurry at various positions in the silo 11114 to move, so that the slurry at different positions can directly contact the heating part 1171 and be heated. Compared with the aforementioned prior art, although the mixing section 1162 may not be able to directly stir the slurry near the inner wall of the first tank body 1111 because the size of the mixing section 1162 is smaller than the size of the silo 11114, the part where the slurry is directly heated is located on the inner side of the entire slurry, and the outer periphery of the slurry will not adhere to the inner wall of the first tank body 1111 due to drying. Moreover, because the slurry itself has a certain viscosity, during the rotation of the mixing section 1162, the part of the slurry that is directly stirred will to a certain extent drive the flow of slurry at other positions, so that the slurry at each position can be moved to other positions to have the opportunity to contact and generate heat with the heating section 1171, thereby making the slurry as a whole evenly heated.

[0047] From another perspective, during the heating process of the slurry, due to the different degrees of heat applied to different parts of the slurry, the slurries located at different positions in the silo 11114 will also undergo a certain degree of heat transfer with each other. The part of the slurry that is heated first will undergo a certain degree of heat exchange with the low-temperature part of the slurry, thereby achieving uniform heating of the entire slurry to a certain extent.

[0048] It should also be noted that in the present embodiment, due to the installation position of the heating part 1171, the inner side of the slurry is in direct contact with the heat source of the heating tank 111. After the moisture in this part of the slurry evaporates due to the heat, moisture migrates to this part of the slurry in the circumferential direction of the slurry to prevent this part of the slurry from drying out. Combined with the stirring action of the mixing part 1162, the slurry that originally lost water will move to other parts, and the moisture migrated from its interior can also migrate to the slurry of the later heated part. In addition, because the first tank body 1111 is sealed during the heating process, the moisture evaporated from the slurry due to heat forms water vapor above the tank body. When the water vapor is saturated, the slurry will not continue to evaporate moisture, so the moisture in the slurry will no longer migrate. Therefore, during the heating process of the slurry, the slurry as a whole can still maintain good viscosity and fluidity.

[0049] Please refer to Figure 6In some embodiments, the heating portion 1171 includes a winding portion 11711a and a conductor 11712. The winding portion 11711a is connected to the power connection terminal 11711b, and the power connection terminal 11711b is electrically connected to the power supply through the mounting through hole 11111b; the winding portion 11711a is wound around the outer circumference of the conductor 11712. When the coil 11711 is energized, the winding portion 11711a is energized to form an alternating magnetic field, so that the conductor 11712 is induced to generate electricity, and then the conductor 11712 is heated due to internal resistance.

[0050] First of all, it is important to understand that electromagnetic heating technology is a heating method that uses electromagnetic fields to generate heat energy. Its principle is to convert electrical energy into heat energy through electromagnetic induction. Specifically, electromagnetic heating technology uses the alternating force of the electromagnetic field to cause the electric charge inside the conductor 11712 to move, thereby generating heat. During the electromagnetic heating process, a power supply is first required to provide electrical energy. The power supply will generate an alternating current, which will generate an alternating magnetic field through the coil 11711. When a conductor 11712 is placed in the alternating magnetic field, the free electrons inside the conductor 11712 will be affected by the electromagnetic force and begin to accelerate. During this process, collisions occur between electrons and atoms in the conductor 11712, causing vibration and friction of the atoms, thereby generating heat energy.

[0051] Since most of the electricity used in daily life and industry is alternating current, in this embodiment, after the winding portion 11711a is connected to the power supply through the power terminal 11711b, the winding portion 11711a generates an alternating magnetic field, and the free electrons inside the conductor 11712 move under the action of the electromagnetic force. The electrons collide with the atoms of the conductor 11712, causing vibration and friction of the atoms, thereby generating heat energy. That is, the winding portion 11711a and the conductor 11712 jointly form a heat source to achieve the heating of the slurry, and the purpose of heating the slurry is achieved by transferring heat to the slurry.

[0052] Since electromagnetic heating technology achieves heating through energy generated by electromagnetic waves or high-frequency induction without direct contact with the heating source and the heated object, non-contact heating can be achieved, which can improve efficiency, reduce energy consumption, and is beneficial to the protection of the heated object and the control of the heating process; in addition, electromagnetic heating technology has the advantages of fast heating speed, high efficiency, and uniform temperature. Therefore, in this embodiment, the heating component 117 has a good heating effect and can be spaced from the slurry to heat it. When a small amount of slurry is added to the silo 11114, the heating tank 111 can also heat process this part of the slurry. In this way, the heating effect of the heating tank 111 is not limited to the volume of the slurry in the silo 11114. In this way, in actual application scenarios, when only a small amount of slurry is left to be processed, the remaining small amount of slurry can be directly heated without the need to replenish and inject sufficient slurry into the silo 11114 again, which saves the time of waiting for the slurry, improves the speed and efficiency of the slurry processing, and at the same time, avoids the waste caused by excessive processing of the slurry.

[0053] In some embodiments, the conductor 11712 is an iron part or a copper part. During the operation of the heating tank 111, eddy currents appear inside the conductor 11712 to generate heat energy, thereby achieving a heating effect. Since iron and copper materials are easy to obtain, the use of iron or copper parts can reduce the manufacturing difficulty and cost of the heating tank 111 to a certain extent.

[0054] Furthermore, the conductor 11712 may be a magnet to enhance the heating effect of the conductor 11712 .

[0055] Please refer to Figure 6 and Figure 7 In some embodiments, the heating component 117 is further provided with a protective cover 1172 covering the heating portion 1171, and the protective cover 1172 is provided with a threading hole 11721 for the power connection end 11711b to pass through, wherein the power connection end 11711b of the coil 11711 passes through the threading hole 11721 to connect to a power source, and the protective cover 1172 is used to isolate the coil 11711, the conductor 11712 and the slurry in the silo 11114 to reduce the degree of corrosion of the conductor 11712 caused by the slurry contacting the conductor 11712, thereby extending the service life of the heating component 117.

[0056] Furthermore, in some embodiments, the wire through hole 11721 is disposed outside the silo 11114. Thus, regardless of whether the diameter of the energized end of the coil 11711 is smaller than the aperture of the wire through hole 11721, during the process of injecting slurry into the silo 11114, since the wire through hole 11721 is located outside the silo 11114, it is difficult for the slurry to enter the protective cover 1172. Thus, the conductor 11712 will not be corroded due to contact with the slurry, thereby extending the service life of the heating component 117 to a certain extent.

[0057] In some embodiments, in order to reduce the impact of water vapor or slurry in the air on the power connection end 11711b, a protective coating 11711c is coated on the surface of the power connection end 11711b so that the power connection end 11711b can be stably connected to the power supply, thereby ensuring the power connection effect of the coil 11711 and allowing the heating component 117 to operate normally.

[0058] Please refer to Figure 5 In some embodiments, the heating tank 111 is further provided with an oscillator 112, and the oscillator 112 is connected between the coil 11711 and the power supply.

[0059] First of all, it is necessary to understand that the amplitude generator 112 is an electronic device used to increase the amplitude of the alternating current signal; electromagnetic heating refers to the heat generated by the internal resistance when the current flows through the conductor 11712. In the alternating current, the magnitude and direction of the current will change periodically, resulting in the generation of alternating resistance inside the conductor 11712, thereby generating heat. The amplitude is the maximum value of the alternating current waveform. The larger the amplitude, the greater the heat generated by the alternating resistance inside the conductor 11712. Therefore, there is a direct correlation between electromagnetic heating and the amplitude of the alternating current. The larger the amplitude, the greater the heat generated inside the conductor 11712.

[0060] In this part of the embodiments, the amplitude device 112 is used to adjust the amplitude of the alternating current, thereby adjusting the heating effect of the conductor 11712. In this way, the temperature of the heating part 1171 changes with the amplitude of the alternating current, so that the heating tank 111 can heat the slurry in the silo 11114 according to the actual needs of the user or the characteristics of the slurry. In this way, the heating tank 111 can heat a variety of slurries, or heat slurries at a variety of temperatures, thereby expanding the application range of the heating tank 111.

[0061] For further information, please refer to Figure 5 In some embodiments, the heating tank 111 is also provided with a controller 113 electrically connected to a power supply, and the controller 113 is electrically connected to the amplitude meter 112; a liquid level meter 114 is installed on the inner wall of the first tank body 1111, and the liquid level meter 114 is used to detect the height of the material body in the silo 11114. The controller 113 is electrically connected to the liquid level meter 114 to obtain the measurement data of the liquid level meter 114 and adjust the output current of the amplitude meter 112 accordingly.

[0062] It should be noted that for different volumes of slurry, in order to enable the slurry to reach the specified temperature, the temperature required to be provided by the heating part 1171 when thermally processing the slurry is different, so the heating degree of the conductor 11712 is different. In order to improve the intelligence of the heating tank 111, a liquid level meter 114 is installed on the inner wall of the first tank body 1111, and a controller 113 is added. The liquid level meter 114 is used to measure the height of the material body. The controller 113 can obtain the measurement data of the liquid level meter 114. According to the measurement data of the liquid level meter 114, the controller 113 controls the amplitude device 112 accordingly to adjust the amplitude of the alternating current, thereby realizing the adjustment of the heating condition of the heating part 1171. The setting of the liquid level meter 114, the controller 113 and the amplitude device 112 can enable the heating tank 111 to spontaneously adjust the heating effect of its heat source, so that the heating component 117 can heat the slurry according to the actual heating needs of the user, thereby improving the intelligence of the heating tank 111.

[0063] For reference Figure 5 and Figure 8 In some embodiments, the heating tank 111 also includes a second tank body 1114, which is separated and surrounded by the outer periphery of the tank body portion 11112 of the first tank body 1111, and limits an insulation bin 111141 together with the tank body portion 11112 of the first tank body 1111. The insulation bin 111141 is filled with an insulation medium 111141b. In this way, when the heating component 117 is working, the insulation medium 111141b can insulate the temperature in the bin 11114 to reduce the heat exchange between the bin 11114 and the outside world, so that the slurry in the bin 11114 can always be in a high temperature environment and can be heated quickly and evenly. In this way, the heating component 117 consumes less power. At the same time, the thermal processing effect and efficiency of the slurry are good, which improves the quality of the thermal processing of the slurry.

[0064] Please continue to refer to Figure 8 In some embodiments, a spiral flow channel 111141a is provided in the heat preservation chamber 111141, and the spiral flow channel 111141a is arranged around the outer circumference of the tank body 11112 and extends along the height direction of the heat preservation chamber 111141. In this way, when the liquid heat preservation medium 111141b is injected into the heat preservation chamber 111141, the liquid heat preservation medium 111141b can flow along the spiral flow channel 111141a and fill the entire heat preservation chamber 111141. Warehouse 111141 is provided to allow the gas in insulation warehouse 111141 to be discharged from insulation warehouse 111141, thereby preventing insulation warehouse 111141 from interfering with its own insulation effect due to the retained gas, thereby improving the insulation effect of insulation warehouse 111141 on silo 11114, and the heating component 117 also reduces energy consumption accordingly due to the reduction of heat exchange between silo 11114 and the outside world, that is, the energy consumption cost of the heating tank 111 is saved.

[0065] Among them, it should be noted that, generally, after the insulation medium 111141b is injected into the insulation bin 111141, in order to prevent the insulation medium 111141b from volatilizing, being contaminated, etc. and affecting the insulation effect of the insulation medium 111141b, the insulation bin 111141 needs to be covered to isolate the insulation medium 111141b from the outside world to ensure the insulation effect of the insulation bin 111141 on the silo 11114.

[0066] Please refer to Figure 5 In some embodiments, the second tank body 1114 is provided with a material injection port 111142, and the silo 11114 is connected to the outside world through the material injection port 111142. The heating tank 111 is also provided with a circulation pump 115, and the circulation pump 115 is connected to the insulation silo 111141 through the material injection port 111142 to provide power for the circulation of the insulation medium 111141b. Among them, under the action of the pumping force of the circulation pump 115, the insulation medium 111141b can flow faster to fill the insulation silo 111141; during the insulation operation of the insulation silo 111141, the insulation medium 111141b can also circulate along the spiral flow channel 111141a under the pumping action of the circulation pump 115, so that the insulation medium 111141b can be evenly heated, so that the insulation in various places in the insulation silo 111141 The medium 111141b has the same thermal insulation capacity for the silo 11114; and because the thermal insulation medium 111141b is heated evenly, the thermal insulation medium 111141b at different positions expands to the same extent, so the thermal insulation silo 111141 will not be squeezed and deformed due to excessive expansion of the local thermal insulation medium 111141b, and the thermal insulation silo 111141 can always maintain its original state, thereby extending the service life of the first tank body 1111 and the second tank body 1114 to a certain extent.

[0067] Please refer again Figure 8 In some embodiments, a spiral step is provided around the outer circumference of the tank body 11112, and the spiral step is spaced apart from the outer wall of the first tank body 1111 and / or the inner wall of the second tank body 1114 to form a spiral flow channel 111141a; or, a spiral groove is provided on the outer wall of the first tank body 1111 and / or the inner wall of the second tank body 1114 to form a spiral flow channel 111141a.

[0068] Among them, the spiral flow channel 111141a is formed by a spiral step arranged around the outer periphery of the tank body 11112. On the one hand, the insulation medium 111141b can flow along the surface of the spiral step and fill the insulation bin 111141 in an orderly manner, and will not splash around due to directly falling to the bottom of the insulation bin 111141; on the other hand, because the spiral step is separated from the outer wall of the first tank body 1111 or the inner wall of the second tank body 1114, when the insulation operation is performed in the insulation bin 111141, the insulation medium 111141b can pass through the spiral step through the gap between the first tank body 1111 or the second tank body 1114 under the pumping action of the circulating pump 115, so that the insulation medium 111141b circulates in the insulation bin 111141, thereby making the temperature of the insulation medium 111141b in various places of the insulation bin 111141 the same.

[0069] The spiral flow channel 111141a is formed by providing a spiral groove on the outer wall of the first tank body 1111 and / or the inner wall of the second tank body 1114, which not only has a certain guiding effect on the thermal insulation medium 111141b, but also the spiral groove expands the space of the thermal insulation bin 111141 to a certain extent, so that the thermal insulation bin 111141 can hold more thermal insulation medium 111141b, thereby improving the thermal insulation capacity of the thermal insulation bin 111141 to a certain extent.

[0070] For reference Figure 5 In some embodiments, the second tank body 1114 is provided with a temperature measuring hole 111143, and the temperature measuring hole 111143 is connected to the heat preservation chamber 111141; the heating tank 111 is also connected to a temperature measuring device 111144, and the temperature measuring tentacles of the temperature measuring device 111144 enter the heat preservation chamber 111141 through the temperature measuring hole 111143 to obtain the temperature of the heat preservation chamber 111141; the heating tank 111 is also provided with a controller 113 electrically connected to a power supply, and the controller 113 is used to obtain the temperature measurement data of the temperature measuring device 111144 to adjust the temperature of the heating part 1171. Due to the heat exchange between the insulation bin 111141 and the silo 11114, the temperature of the insulation bin 111141 can be known by detecting the temperature of the insulation bin 111141, that is, the heating condition of the slurry can be obtained, thereby indirectly knowing the heating effect of the heating component 117. Therefore, according to the temperature measurement data of the temperature measuring device 111144, the temperature of the heating part 1171 is adjusted to achieve the regulation of the heating condition of the slurry; in addition, if the temperature of the insulation medium 111141b is in a low temperature state for a long time, it proves that the insulation effect of the insulation medium 111141b is poor. At this time, the insulation medium 111141b needs to be replaced so that the insulation bin 111141 has a good insulation effect.

[0071] In other embodiments, a thermometer 11131 is installed on the top plate 11111, and the thermometer 11131 is used to measure the temperature in the silo 11114, so as to intuitively feed back the temperature in the silo 11114 to the user, so that the user can understand the actual processing status of the slurry in time.

[0072] Viewable Figure 4 In some embodiments, the first tank body 1111 is provided with a transparent window 11115 for the user to manually view the processing status of the slurry in the silo 11114, so that the user can judge the thermal processing status of the slurry based on the viscosity of the slurry seen. If it is judged that the slurry is abnormally processed, timely measures can be taken; in addition, when injecting slurry into the silo 11114, the actual injection amount of the slurry can also be viewed through the window to prevent excessive injection of slurry, which may cause safety hazards during the use of the heating tank 111.

[0073] Please refer to Figure 3 and Figure 5 In some embodiments, the first tank body 1111 is equipped with a barometer 1112 for detecting the air pressure of the silo 11114. During the operation of the heating tube, the air pressure inside the silo 11114 will increase due to the increase in internal temperature. The air pressure inside the silo 11114 needs to be controlled to prevent the heating tank 11114 from exploding due to excessive internal air pressure. By setting the barometer 1112, the user can timely know the air pressure in the silo through the barometer 1112 and timely determine whether pressure relief measures need to be taken, thereby improving the safety of the heating tank 111.

[0074] For reference Figure 5 In some embodiments, the first tank body 1111 is equipped with a flow meter 1113 for obtaining the flow of the inlet 11111a. In this way, the flow meter 1113 can obtain the flow of the slurry injected from the inlet 11111a, thereby obtaining the amount of slurry injected into the silo 11114. In this way, when the slurry reaches the user's usage, the user can be informed in time and stop further injection; the flow meter 1113 can also assist the user to avoid injecting too much slurry into the silo, resulting in unsatisfactory slurry heating effect.

[0075] You can continue to refer to Figure 5 In some embodiments, the rotating body 1161 includes fan blades 11611, and the fan blades 11611 are inclined in the rotation direction of the rotating body 1161. In this way, when the fan blades 11611 rotate, the fan blades 11611 can drive the slurry to mix in both horizontal and vertical directions, so that the slurry in various places in the silo 11114 can be driven to move by the fan blades 11611, preventing local slurry from accumulating in one place, thereby improving the heating efficiency of the heating tank 111 to a certain extent.

[0076] In some embodiments, the rotating body 1161 is rotatably connected to a connecting end 11612, which is used to connect to the fan blades 11611. The connecting end 11612 can rotate synchronously with the rotating body 1161 to drive the fan blades 11611 to rotate, thereby achieving stirring of the slurry in the silo 11114.

[0077] You can continue to refer to Figure 5 In some embodiments, the bottom of the first tank body 1111 is a conical surface, and the discharge port 111131 of the heating tank 111 is located at the bottom of the conical surface. In this way, the conical surface can guide the slurry to flow out of the silo 11114 from the discharge port 111131 to prevent the slurry from accumulating and remaining at the bottom of the first tank body 1111, affecting the subsequent thermal processing effect of the slurry.
