Description

Technical Field

[0001] The present invention relates to the technical field of green anode processing, and particularly to a device for preventing high-temperature paste from sticking. Background Art

[0002] The green anode manufacturing process is a key process in the production of pre-baked anodes. It includes the most process steps and the most factors affecting the anode quality, such as the crushing and grinding methods of calcined coke, the purity of sieved powder, the particle size composition of dry materials, the batching method, the amount of binder, the kneading and forming process conditions, etc. These often cause the plasticity of the paste to be erratic, making it difficult to correctly control during anode forming, resulting in a large number of cracked waste products in subsequent processes.

[0003] High-temperature kneading is a leading kneading technology in the industry. It takes advantage of the fact that the viscosity of asphalt does not change significantly after 180°C, making the viscosity and state of the paste controllable. The proportion of asphalt in the paste is about 16%. The asphalt has a relatively high viscosity and is prone to sticking. During kneading, through the adjustment of various parameters, it is ensured to be within a controllable range. However, during transportation, the paste is easily adhered to the inner wall of the transportation channel and is very difficult to clean.

[0004] Patent No.: 201220097474.9, Patent Name: A Chinese Patent for an Anti-adhesion Feeding Pipe for Green Anode Forming Paste for Electrolytic Aluminum, records that by setting a jacket outside the material pipe and passing cooling water between the jacket and the material pipe, the material pipe and the paste in contact with the inner wall of the material pipe are cooled by the cooling water, so that the surface of a part of the paste on the inner wall of the tight material pipe is quickly cooled and solidified. Since the solidified asphalt does not have viscosity, the purpose of anti-adhesion is achieved. However, cooling the entire pipeline will consume a large amount of cooling water, and the overall temperature of the paste will be reduced significantly, affecting the plasticity of the paste and being unfavorable for the processing in the forming stage. Therefore, the present invention provides a device for preventing high-temperature paste from sticking with better use effects. Summary of the Invention

[0009] The side of the material conveying channel is fixedly connected with a buffer tank through a bracket. The buffer tank is cylindrical, and a water inlet and a drainage component are respectively arranged at both ends. A plurality of branch pipes are arranged between the side of the buffer tank and the bottom end of the main blade-type heat dissipation water tank;

[0010] It also includes: a high-pressure pulse pump, and the water outlet end of the high-pressure pulse pump is connected to the water inlet through a pipeline.

[0011] Preferably, one side of both the main blade-type heat dissipation water tank and the secondary blade-type heat dissipation water tank fits the surface of the material conveying channel.

[0012] Preferably, the bottom end of the material conveying channel is connected to a discharge channel. The upper part of the discharge channel is an inclined section and the lower part is a vertical section. An inclined opening is arranged at the bottom end of the discharge channel, and a discharge plate is fixedly connected to the bottom end of the discharge channel.

[0013] Preferably, connecting flanges are arranged at the bottom end of the material conveying channel and the top end of the discharge channel, and the two connecting flanges are fixedly connected through a bolt group.

[0014] Preferably, the shape of the secondary blade-type heat dissipation water tank is U-shaped, and a plurality of horizontal branches and T-shaped heat dissipation connectors are connected between the two side walls of the U-shaped. Both ends of the horizontal branch are communicated with the secondary blade-type heat dissipation water tank.

[0015] Preferably, an L-shaped heat dissipation connector is arranged on the side of the material conveying channel. One end of the L-shaped heat dissipation connector is fixedly connected to the main blade-type heat dissipation water tank, and the other end is fixedly connected to the secondary blade-type heat dissipation water tank.

[0016] Preferably, it also includes: a water tank. The water inlet end of the high-pressure pulse pump is connected to the water tank through a pipeline, and the water outlet is connected to the water tank through a pipeline.

[0019] Preferably, an oil injection structure is provided on the front side / rear side of the material conveying channel, and the nozzle is located inside the material conveying channel.

[0020] (III) Beneficial effects

[0021] The present invention provides a device for preventing high-temperature paste from sticking. It has the following beneficial effects:

[0022] 1. In the present invention, the material conveying channel is set to be inclined. When the paste is conveyed downward, it will follow the lower inner inclined wall. The main blade type radiator tank is arranged below this side wall, which can achieve efficient and rapid heat dissipation, thus preventing the problem of high-temperature paste sticking. Compared with setting a circular cooling water channel, it has precise heat dissipation, avoids paste sticking, and at the same time does not greatly affect the overall temperature of the paste, which is beneficial to the subsequent forming process. Although most of the paste is conveyed along the lower side wall when the paste is conveyed, when the paste is conveyed quickly, part of it will contact the upper inner inclined wall of the material conveying channel and even fill the entire channel. In this solution, the auxiliary blade type radiator tank is used to cool the upper inner inclined wall, and the front and rear sides of the material conveying channel are cooled by the one-way water inlet branch and the one-way water outlet branch, ensuring good use effects.

[0023] 2. In the present invention, a high-pressure pulse pump is used in cooperation with a buffer tank to convey cooling water to the main blade type radiator tank. That is, when a pulse is conveyed, the pressure in the main blade type radiator tank will increase, and part of the cooling water will enter the auxiliary blade type radiator tank through the one-way water inlet branch (the water pressure in the auxiliary blade type radiator tank increases). As the water in the main blade type radiator tank is discharged from the water outlet, the water pressure in the main blade type radiator tank decreases, and the water in the auxiliary blade type radiator tank flows back to the main blade type radiator tank through the one-way water outlet branch and then is discharged from the water outlet. Using this principle, the high-pressure pulse pump is controlled to work at a high frequency, and the cooling effect at the positions where the auxiliary blade type radiator tank, the one-way water inlet branch, and the one-way water outlet branch are located is improved. When the high-pressure pulse pump is controlled to work at a low frequency, the main blade type radiator tank has a good working state, that is, it can cope with two working states of rapid feeding and slow feeding.

Specific Embodiment

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1:

[0035] As Figures 1 - 8 shown, the embodiment of the present invention provides a device for preventing high-temperature paste from sticking, including a discharge channel 1, a material conveying channel 2, a high-pressure pulse pump 11, and a water tank 12. The material conveying channel 2 is inclined. As shown in the attached Figure 4 and Figure 6 figures, when the high-temperature paste is conveyed from top to bottom, it contacts the inner wall of the lower material conveying channel 2. Only when the material conveying is relatively fast, will part of the high-temperature paste contact the inner wall of the upper material conveying channel 2.

[0036] Refer to the attached Figures 1 - 6, the bottom end of the material feeding channel 2 is connected to the discharge channel 1. The upper part of the discharge channel 1 is an inclined section and the lower part is a vertical section. The inclined section matches the bottom end of the material feeding channel 2. That is, connecting flanges are provided at the bottom end of the material feeding channel 2 and the top end of the discharge channel 1. The two connecting flanges are fixedly connected by a bolt group, enabling detachable connection between the discharge channel 1 and the material feeding channel 2. After using for a period of time, the discharge channel 1 can be disassembled to clean the paste adhered to the inner wall. The bottom end of the discharge channel 1 is provided with an inclined opening, which is convenient for a cleaning tool with a long rod to extend into the interior of the discharge channel 1 to generally clean the inner wall. The bottom end of the discharge channel 1 is fixedly connected to a discharge plate 8. Multiple material feeding channels 2 and discharge channels 1 are arranged in parallel in the factory. The discharge plate 8 connects the bottom ports of multiple discharge channels 1, making it more stable.

[0037] Reference appendix Figures 1 - 6 , on the lower oblique surface of the material feeding channel 2, there is a main blade type heat dissipation water tank 3. The main blade type heat dissipation water tank 3 is a thin-walled hollow shell. Cooling water flows inside the shell to quickly cool the lower oblique surface area of the material feeding channel 2, thereby cooling the high-temperature paste passing through this area and playing a role in preventing sticking of materials. At the top of the main blade type heat dissipation water tank 3, there is a water outlet 4, and a pressure valve is connected to the water outlet 4. It is ensured that the cooling water inside the main blade type heat dissipation water tank 3 will flow out through the water outlet 4 only when it has a certain pressure. The water outlet 4 is connected to the water tank 12 through a pipeline, that is, it flows into the water tank 12. On the upper oblique surface of the material feeding channel 2, there is a secondary blade type heat dissipation water tank 7. Between the secondary blade type heat dissipation water tank 7 and the main blade type heat dissipation water tank 3, there are a one-way water inlet branch 9 and a one-way water outlet branch 10. The one-way water inlet branch 9 and the one-way water outlet branch 10 are respectively located on the front and back side surfaces of the material feeding channel 2, and both the one-way water inlet branch 9 and the one-way water outlet branch 10 are in contact with the surface of the material feeding channel 2 to realize cooling on both sides of the material feeding channel 2. The cooling water in the main blade type heat dissipation water tank 3 will flow into the secondary blade type heat dissipation water tank 7 through the one-way water inlet branch 9 under certain conditions and flow back to the main blade type heat dissipation water tank 3 through the one-way water outlet branch 10 under another condition, realizing cooling of the inner side wall of the material feeding channel 2 at the one-way water inlet branch 9, the one-way water outlet branch 10, and the secondary blade type heat dissipation water tank 7.

[0038] The side of the material feeding channel 2 is fixedly connected to a buffer tank 5 through a bracket. The buffer tank 5 is cylindrical, and water inlets 6 and a drainage component 13 are respectively provided at both ends. A valve body is provided at the drainage component 13, which is opened when it is necessary to relieve pressure inside the main blade type heat dissipation water tank 3. Between the side of the buffer tank 5 and the bottom end of the main blade type heat dissipation water tank 3, there are several branch pipes.

[0039] The water outlet end of the high-pressure pulse pump 11 is connected to the water inlet 6 through a pipeline, and the water inlet end of the high-pressure pulse pump 11 is connected to the water tank 12 through a pipeline.

[0040] When the high-pressure pulse pump 11 is working, it extracts water from the water tank 12 and delivers it to the buffer tank 5 in the form of a pulse. By using the axial length of the cylindrical structure of the buffer tank 5 for buffering, it can prevent the high-pressure water from damaging the inner wall of the main blade type heat dissipation water tank 3. One pulse of water injection will increase the water pressure inside the main blade type heat dissipation water tank 3. At this time, part of the cooling water will be directly discharged through the water outlet 4, and part of the cooling water will enter the secondary blade type heat dissipation water tank 7 through the one-way water inlet branch 9, increasing the water pressure in the secondary blade type heat dissipation water tank 7. After part of the water is discharged from the water outlet 4, the water pressure inside the main blade type heat dissipation water tank 3 returns to its original value. At this time, the cooling water in the high-pressure secondary blade type heat dissipation water tank 7 flows back to the main blade type heat dissipation water tank 3 through the one-way water outlet branch 10 and then flows to the water tank 12 through the water outlet 4. One pulse causes the above-mentioned action once, that is, one cycle of water circulation is completed, achieving the effect of cooling the inside of the feeding channel 2.

[0041] In the above action, the cooling water in the main blade type heat dissipation water tank 3 circulates the most and has the best cooling effect. The cooling water in other parts is only used in small amounts, that is, it realizes efficient cooling of the lower oblique surface of the feeding channel 2.

[0042] In one pulse, the cooling water in the secondary blade type heat dissipation water tank 7, the one-way water inlet branch 9, and the one-way water outlet branch 10 circulates a small amount once. By high-frequency pulsed water delivery, the increase in the cooling effect at this place can be controlled, and it can be specifically controlled according to the situation.

[0043] Reference appendix Figure 6 As shown in the figure, both the main blade type heat dissipation water tank 3 and the secondary blade type heat dissipation water tank 7 have one side surface that fits the surface of the feeding channel 2. Only by fitting can a better cooling effect be ensured.

[0044] Reference appendix Figure 6 As shown in the figure, the shape of the secondary blade type heat dissipation water tank 7 is set to a U shape, and several horizontal branches 15 and T-shaped heat dissipation connectors 16 are connected between the two side walls of the U shape. Both ends of the horizontal branch 15 are communicated with the secondary blade type heat dissipation water tank 7.

[0045] The horizontal branch 15 enables the cooling water at the two side walls of the U shape to directly circulate, ensuring the uniformity of the internal cooling water. One function of the T-shaped heat dissipation connector 16 is to connect the secondary blade type heat dissipation water tank 7, and the other function is to increase the cooling effect of the side wall of the feeding channel 2.

[0046] The design of the U-shaped structure enables the secondary blade type heat dissipation water tank 7 to have a better cooling effect on the corners of the feeding channel 2, and the cooling effect in the middle is slightly worse. The purpose is to solve the problem that the inner corners of the feeding channel 2 are prone to sticking and caking of the paste material.

[0047] Reference appendixFigures 2 - 3 On the side of the material conveying channel 2, an L-shaped heat dissipation connecting piece 14 is provided. One end of the L-shaped heat dissipation connecting piece 14 is fixedly connected to the main blade type heat dissipation water tank 3, and the other end is fixedly connected to the secondary blade type heat dissipation water tank 7.

[0048] One function of the L-shaped heat dissipation connecting piece 14 is to connect the main blade type heat dissipation water tank 3 and the secondary blade type heat dissipation water tank 7, and another function is to enhance the cooling effect.

[0049] Embodiment 2:

[0050] The difference between this embodiment and Embodiment 1 is that a refrigerator is provided inside the water tank 12, and the refrigerator cools the water in the water tank 12, aiming to enhance the cooling effect during the circulation process.

[0051] An oil injection structure is provided on the front side / rear side of the material conveying channel 2, and the nozzle is located inside the material conveying channel 2. The oil injection structure injects oil onto the inner side wall of the material conveying channel 2 to reduce the adhesion of the inner side wall of the material conveying channel 2, and in cooperation with the cooling structure, a better anti-adhesion effect is achieved.

[0052] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
