Description

Technical Field

[0001] The utility model relates to the field of positive pressure conveying tanks, in particular to a feed port of a positive pressure conveying tank. Background Art

[0002] Pneumatic conveying refers to a method of conveying granular materials in a closed pipe along the direction of airflow using the energy of airflow. It is a specific application of fluidization technology. Pneumatic conveying has the advantages of large conveying volume, long conveying distance and high conveying speed. It is widely used in industries such as lithium batteries, cement and minerals. Pneumatic conveying is generally divided into two forms: positive pressure conveying and negative pressure conveying. The existing positive pressure conveying system requires the use of positive pressure conveying tanks.

[0003] The existing powder positive pressure conveying tank feed valve generally uses a single valve as the tank feed port. When this valve is damaged, the pressure in the tank causes damage to the upper feed soft connection, resulting in material spraying and material loss, which is likely to cause blockage in the positive pressure conveying pipeline. In addition, the valve must be repaired immediately after it is damaged, delaying the production rhythm and affecting the equipment utilization rate. This equipment is a key equipment. After the equipment is damaged, the material in the previous process cannot be processed, causing the entire line to stop production.

[0004] In summary, the above structure is very likely to cause material spraying and material loss when the valve is damaged, and at the same time causes the positive pressure conveying pipeline to be blocked. In addition, the subsequent staff will waste too much time when replacing it, which reduces the overall replacement efficiency and increases the workload of the staff. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a positive pressure conveying tank feed port to solve the technical problems that when the valve is damaged, it is very easy to cause material spraying or blockage, and the subsequent replacement wastes too much time, reduces the overall replacement efficiency, and increases the workload of the staff.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a positive pressure conveying tank feed port, including a bracket, a tank body is arranged on the bracket, and a silo is connected to the top of the tank body, a hose is arranged at the bottom of the silo, and a slide pipe is connected to the top of the hose, a first valve and a second valve are arranged at both the upper and lower ends of the slide pipe, a slide plate is slidably arranged in the slide pipe, and limiting columns are symmetrically arranged at the bottom of the slide plate, and a limiting groove cooperating with the limiting column is opened on the second valve.

[0007] By adopting the above technical scheme, if the second valve is damaged during the transportation process, it will be detected and alarmed through the action of the pressure detection gauge body. At the same time, under the action of the first valve, it is avoided that the hose is damaged due to high pressure and then the material is sprayed out, or the tank pressure is insufficient, which makes it impossible to transport the material to the subsequent process and cause blockage. In addition, a slide plate is slidingly arranged in the slide pipe. When the air pressure in the slide pipe is too high, the slide plate will drive the limit column at the bottom to slide upward, so that the limit column slides out of the limit groove of the second valve, so that the staff can directly disassemble it, which speeds up the overall maintenance efficiency and reduces the workload of the staff.

[0008] The utility model is further configured that an opening is provided in the middle of the slide plate, and the diameter at the top of the opening is greater than the diameter at the bottom thereof.

[0009] By adopting the above technical solution, when the material in the silo falls to the bottom through the silo valve and the first valve, the open setting facilitates the material to pass through the slide plate. At the same time, the larger diameter of the opening top effectively reduces the accumulation of materials on the top of the slide plate, and the smaller diameter of the bottom can increase the contact area between the slide plate and the air pressure when the air pressure is from the bottom upward, thereby ensuring that the slide plate can slide upward stably in the slide pipe.

[0010] The utility model is further configured that the top of the hose is located at the bottom of the silo and a silo valve is provided.

[0011] By adopting the above technical solution, it is convenient for the staff to control the discharge of the silo materials through the action of the silo valve, thereby further improving the overall practicality of the device.

[0012] The utility model is further configured that the limit post and the limit groove are arranged in a rough shape.

[0013] By adopting the above technical solution, the rough setting facilitates to improve the sliding friction between the limit column and the limit groove, effectively preventing the slide plate from shifting in the slide pipe during the blanking process, and ensuring the overall stability of the slide plate.

[0014] The utility model is further configured such that a pressure detection gauge body is provided on the outer wall of the slide pipe between the first valve and the second valve.

[0015] By adopting the above technical solution, the air pressure between the first valve and the second valve is generally set to 0.15Mpa under normal conditions. When the second valve is damaged, the air pressure inside the tank will be discharged upward into the slide pipe. At this time, the pressure detection gauge body detects the high pressure and outputs a signal to the control system, triggering an alarm to prompt the operator to perform maintenance, thereby effectively reducing the risks in the overall operation of the device.

[0016] The utility model is further configured such that a seal is provided between the pressure detection gauge body and the slide pipe.

[0017] By adopting the above technical solution, the sealed setting can prevent the internal air pressure from leaking out, causing the pressure inside the tank to fail to reach a certain air pressure, thereby affecting the transportation of materials in the tank.

[0018] The utility model is further configured such that the slide pipe and the tank body are detachably arranged.

[0019] By adopting the above technical solution, the detachable setting makes it easy for subsequent staff to maintain and replace the slide pipe, thereby increasing the overall service life of the device.

[0020] The utility model is further configured that a plurality of supporting legs are arranged at the bottom of the bracket.

[0021] By adopting the above technical solution, the support leg props up the entire bracket, thereby effectively preventing dirt and impurities on the ground from contaminating the outer wall of the tank.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model is provided with a first valve and a second valve at the upper and lower ends of the slide pipe respectively. If the second valve is damaged during the conveying process, it will be detected and alarmed through the action of the pressure detection gauge body. At the same time, under the action of the first valve, it is avoided that the hose is damaged and then sprayed or the tank pressure is insufficient, which makes it impossible to convey the material to the subsequent process and cause blockage. In addition, a slide plate is slidingly arranged in the slide pipe. When the air pressure in the slide pipe is too high, the slide plate will drive the limit column at the bottom to slide upward, so that the limit column slides out of the limit groove of the second valve, so that the staff can directly disassemble it, which speeds up the overall maintenance efficiency and reduces the workload of the staff.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] Embodiment 1

[0032] A positive pressure conveying tank feed port, such as Figure 1-Figure 4 As shown, it includes a bracket 1, a silo 2, a tank body 5, a sealing mechanism, a limit mechanism and a detection mechanism. The tank body 5 is arranged on the bracket 1, and the top of the tank body 5 is connected with the silo 2. The staff puts the material to be discharged in the silo 2. At the same time, a silo valve 4 is arranged at the top of the hose 3 and at the bottom of the silo 2. The silo valve 4 is convenient for the staff to control the discharge of the material in the silo 2, which further improves the overall practicality of the device. A hose 3 is arranged at the bottom of the silo 2, and a slide pipe 9 is connected at the top of the hose 3, wherein the first valve 8 and the second valve 11 are arranged at the upper and lower ends of the slide pipe 9. By opening the silo valve 4, the first valve 8 and the second valve 11, the compressed air in the sending silo is used to transport the material. Since the pressure detection gauge body 10 is arranged on the outer wall of the slide pipe 9 between the first valve 8 and the second valve 11 Under normal conditions, the air pressure between the first valve 8 and the second valve 11 is generally set to 0.15Mpa. When the second valve 11 is damaged, the air pressure inside the tank 5 will be discharged upward into the slide pipe 9. At this time, the pressure detection gauge body 10 detects high pressure and outputs a signal to the control system, triggering an alarm to prompt the operator to perform maintenance, effectively reducing the risks in the overall operation of the device, and a slide plate 6 is slidably arranged in the slide pipe 9, and a limit column 7 is symmetrically arranged at the bottom of the slide plate 6. At the same time, a limit groove 12 cooperating with the limit column 7 is opened on the second valve 11. When the air pressure in the slide pipe 9 is too high, the slide plate 6 will drive the limit column 7 at the bottom to slide upward, so that the limit column 7 slides out of the limit groove of the second valve 11, so that it is convenient for the staff to directly disassemble it, which speeds up the overall maintenance efficiency and reduces the workload of the staff.

[0033] See also Figure 2A rough shape is provided between the limit column 7 and the limit groove 12. The rough shape facilitates to improve the sliding friction between the limit column 7 and the limit groove 12, effectively preventing the slide plate 6 from being displaced in the slide pipe 9 during the blanking process, thereby ensuring the overall stability of the slide plate 6.

[0034] Embodiment 2

[0035] like Figure 2 A positive pressure conveying tank feed port is shown, and its overall structure is similar to that of the embodiment, wherein an opening is provided in the middle of the slide plate 6, and the diameter at the top of the opening is larger than the diameter at the bottom thereof. When the material in the silo 2 falls to the bottom through the silo valve 4 and the first valve 8, the opening-shaped setting facilitates the material to pass through the slide plate 6. At the same time, the larger diameter at the top of the opening effectively reduces the accumulation of the material on the top of the slide plate 6, and the smaller diameter at the bottom can increase the contact area between the slide plate 6 and the air pressure when the air pressure is applied from the bottom upward, thereby ensuring that the slide plate 6 can slide upward stably in the chute 9.

[0036] The working principle of the utility model is as follows: when in use, by opening the silo valve 4, the first valve 8 and the second valve 11, the material in the silo 2 falls into the tank body 5 at the bottom through the silo valve 4, and then the silo valve 4, the first valve 8 and the second valve 11 are closed, and the compressed air in the silo is sent to transport the material. Under normal conditions, the air pressure between the first valve 8 and the second valve 11 is generally set to 0.15Mpa. When the second valve 11 is damaged, the internal air pressure is monitored in real time by the pressure detection gauge body 10, and the detection alarm is issued at the same time. Under the action of the first valve 8, the situation that the high pressure causes the hose 3 to be damaged and then the spraying of the material or the insufficient tank pressure causes the material to be unable to be transported to the subsequent process and causes the material to be blocked is avoided. At the same time, when the air pressure enters the slide pipe 9, it will drive the slide plate 6 in the slide pipe 9 to move upward. In this process, the slide plate 6 drives the limit column 7 to slide out of the limit groove 12 of the second valve 11. At this time, the limit work of the second valve 11 is released, so that it is convenient for the staff to directly disassemble it, which speeds up the overall maintenance efficiency and reduces the workload of the staff.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
