Description

Technical Field

[0001] This utility model relates to the field of mill feed tank technology, and more specifically, to a feed tank and a mill having the same. Background Technology

[0002] Currently, a feeding tank is a device used to feed powdered materials (such as bulk food, industrial raw materials, and pharmaceuticals). A valve controls the feeding of materials from the inlet into a powder conveying pipeline, then into a storage tank, which in turn feeds the material into the next process step. To ensure material quality, samples need to be taken, and the quality feedback is provided to the producer to control the production process.

[0003] In existing technology, the sampling method for the mill's feeding tank involves welding a DN15 galvanized pipe into the powder conveying pipeline, and then controlling the opening and closing of the angle seat valve to achieve sampling. However, due to the large sample volume and frequent sampling, the angle seat valve is prone to wear, which not only easily leads to material blockage, affecting the uniformity of the sampled powder, but also results in a large number of angle seat valve replacements throughout the year. Utility Model Content

[0004] The main objective of this invention is to provide a sending tank and a mill having the same, in order to solve the problem that the angle seat valve of the mill sending tank is prone to wear due to the large sampling volume and frequent sampling in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a delivery tank is provided, comprising: a delivery tank body; a delivery pipe communicating with the delivery tank body; a sampling pipe, the first end of which extends into the delivery pipe and extends downward at an angle; a control valve disposed on the sampling pipe for controlling the on / off state of the sampling pipe and / or the sample flow rate or velocity within the sampling pipe; and a backflush device disposed within the sampling pipe or located on one side of the sampling pipe; wherein, when the control valve is in the closed state, the backflush device blows air or sprays liquid in a preset direction to cause the sample buffered in the sampling pipe to flow back into the delivery pipe via the first end.

[0006] Furthermore, the end face of the first end is an inclined surface, which slopes downwards.

[0007] Furthermore, the vertical distance h from the first end extending into the conveying pipe is greater than or equal to 6 cm and less than or equal to 10 cm.

[0008] Furthermore, the delivery pipe has a through hole, and the first end extends into the delivery pipe after passing through the through hole; the delivery tank also includes a sealing structure, which is disposed between the through hole and the sampling pipe.

[0009] Furthermore, the delivery tank also includes: a branch pipe, the first end of which is connected to the middle of the sampling pipe; a tube valve, which is installed on the second end of the branch pipe; wherein, the backflushing device is installed inside the delivery pipe and located between the control valve and the first end of the sampling pipe, and the connection between the branch pipe and the sampling pipe is located between the control valve and the first end of the sampling pipe.

[0010] Furthermore, the delivery tank also includes: a first timing device for timing the closing time of the control valve; a second timing device for timing the running time of the tubular valve; and a control module electrically connected to both the control valve and the tubular valve; wherein, when the timing value of the first timing device is 'a', the tubular valve is started by controlling the control module until the timing value of the second timing device reaches 'b', at which point the tubular valve is closed by controlling the control module; 0 < a ≤ 4s, 0 < b ≤ 8s.

[0011] Furthermore, the control module is electrically connected to the backflushing device. After the control module controls the start of the tube valve, the control module controls the start of the backflushing device; and / or, the backflushing device includes a fan, the outlet of which is positioned facing the first end of the sampling pipe.

[0012] Furthermore, a zinc layer is plated on the outer surface of the sampling pipe.

[0013] Furthermore, the inner diameter of the branch pipe is smaller than the inner diameter of the sampling pipe.

[0014] According to another aspect of the present invention, a mill is provided, including the aforementioned feeding tank.

[0015] The present invention provides a sending tank comprising a sending tank body, a conveying pipe, a sampling pipe, a control valve, and a backflushing device. The conveying pipe is connected to the sending tank body. The control valve is located on the sampling pipe to control the on / off state of the sampling pipe and / or the sample flow rate or velocity within the sampling pipe. The backflushing device is located inside the sampling pipe or on one side of the sampling pipe. Thus, the first end of the sampling pipe extends into the conveying pipe and slopes downwards. Through the cooperation of the control valve, the sampling pipe, and the backflushing device, this invention replaces the existing method of sampling using an angle seat valve, thereby solving the problem of easy wear of the angle seat valve in existing mill sending tanks due to the large sample volume and frequent sampling. When material sampling is required, the control valve is opened, and the material flows along the pipe wall of the sampling pipe under its own weight, so that the staff can take samples. After sampling is completed, the control valve is closed. When the control valve is closed, the backflushing device blows air or sprays liquid in a preset direction, so that the sample buffered in the sampling pipe flows back to the conveying pipe through the first end, thereby avoiding material waste.

[0024] To address the problem of easy wear of the angle seat valve in the existing mill feed tank due to the large sampling volume and frequent sampling, this application provides a feed tank and a mill having the same.

[0025] like Figure 1 and Figure 2As shown, the sending tank includes a sending tank body 10, a delivery pipe 20, a sampling pipe 30, a control valve 40, and a backflush device. The delivery pipe 20 is connected to the sending tank body 10. The first end of the sampling pipe 30 extends into the delivery pipe 20 and extends downward at an angle. The control valve 40 is provided on the sampling pipe 30 to control the on / off state of the sampling pipe 30 and / or the sample flow rate or velocity within the sampling pipe 30. The backflush device is provided inside the sampling pipe 30 or located on one side of the sampling pipe 30. When the control valve 40 is in the closed state, the backflush device blows air or sprays liquid in a preset direction to cause the sample buffered in the sampling pipe 30 to flow back into the delivery pipe 20 via the first end.

[0026] Applying the technical solution of this embodiment, the first end of the sampling pipe 30 extends into the conveying pipe 20 and extends downward at an angle. Through the cooperation between the control valve 40, the sampling pipe 30, and the backflushing device, the sampling method using an angle seat valve in the prior art is replaced, thereby solving the problem of easy wear of the angle seat valve in the mill's feeding tank due to the large sampling volume and frequent sampling in the prior art. When it is necessary to sample the material, the control valve 40 is opened, and the material flows along the pipe wall of the sampling pipe 30 under its own weight, so that the operator can take a sample. After the sampling is completed, the control valve 40 is closed. When the control valve 40 is in the closed state, the backflushing device blows air or sprays liquid in a preset direction, so that the sample buffered in the sampling pipe 30 flows back into the conveying pipe 20 through the first end, thereby avoiding material waste.

[0027] like Figure 1 and Figure 2 As shown, the end face of the first end is an inclined surface 31, which slopes downwards. This inclined surface 31 allows gravity to assist in sample reflux, especially when processing high-viscosity or easily sedimenting materials. It more effectively removes residual samples from the sampling pipe 30, ensuring the cleanliness of the sampling pipe 30.

[0028] Optionally, the vertical distance h from the first end extending into the delivery pipe 20 is greater than or equal to 6 cm and less than or equal to 10 cm. This vertical distance h setting not only ensures the representativeness of the sample during sampling, but also allows the airflow or liquid flow to more effectively impact the residual sample within the sampling pipe 30 during backflushing, thus improving backflushing efficiency.

[0029] In this embodiment, the vertical distance h from the first end extending into the delivery pipe 20 is 8 cm. This arrangement not only improves the assembly stability of the delivery pipe 20 and the sampling pipe 30, ensuring that the sampling pipe 30 can take samples normally, but also avoids structural interference between the first end and the inner wall of the delivery pipe 20, which could cut or scratch the delivery pipe 20.

[0030] It should be noted that the value of the vertical distance h from the first end extending into the conveying pipe 20 is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, the vertical distance h from the first end extending into the conveying pipe 20 can be 6.5cm, 6.8cm, 7.0cm, 7.2cm, 7.5cm, 7.8cm, 8.2cm, 8.5cm, 8.8cm, 9.0cm, 9.5cm, or 9.8cm.

[0031] Optionally, the conveying pipe 20 has a through hole, with the first end passing through the through hole and extending into the conveying pipe 20. The sending tank also includes a sealing structure. The sealing structure is disposed between the through hole and the sampling pipe 30. This sealing structure effectively prevents material leakage during the conveying process, ensuring the safety and stability of the mill.

[0032] Optionally, the sealing structure is a sealing ring.

[0033] Optionally, there is one sealing structure; or there are multiple sealing structures, which are spaced apart along the extension direction of the through hole.

[0034] Alternatively, the sealing structure may be made of silicone or rubber.

[0035] like Figure 1 As shown, the sending tank also includes a branch pipe 50 and a tube valve 60. The first end of the branch pipe 50 is connected to the middle of the sampling pipe 30. The tube valve 60 is located on the second end of the branch pipe 50. The backflushing device is located inside the conveying pipe 20 and between the control valve 40 and the first end of the sampling pipe 30. The connection between the branch pipe 50 and the sampling pipe 30 is located between the control valve 40 and the first end of the sampling pipe 30. Thus, the aforementioned arrangement of the branch pipe 50 and the tube valve 60 isolates the sampling pipe 30 from the conveying pipe 20, preventing backflushing from affecting the material inside the conveying pipe 20. Simultaneously, the independent design of the branch pipe 50 and the sampling pipe 30 ensures that sampling and backflushing operations do not interfere with each other, enabling accurate sampling and analysis while ensuring continuous operation of the production line.

[0036] Optionally, the sending tank also includes a first timing device, a second timing device, and a control module. The first timing device is used to time the closing time of the control valve 40. The second timing device is used to time the operating time of the tubular valve 60. The control module is electrically connected to both the control valve 40 and the tubular valve 60. Specifically, when the timing value of the first timing device is 'a', the control module controls the tubular valve 60 to start, and when the timing value of the second timing device reaches 'b', the control module controls the tubular valve 60 to close; 0 < a ≤ 4s, 0 < b ≤ 8s. Simultaneously, the coordinated use of the first timing device, the second timing device, and the control module enables precise control of the sampling and backflushing processes, improving automation and reducing manual operation.

[0037] In this embodiment, a = 2s, b = 5s. After the material is delivered from the sending tank or sampling is completed, the control valve 40 is closed. After waiting for 2 seconds, the control module activates the tube valve 60, which in turn activates the backflushing device to prevent material blockage in the sampling pipeline 30. After the tube valve 60 has been running for 5 seconds, the control valve 60 and the backflushing device are closed.

[0038] It should be noted that the value of 'a' is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, a = 1s, a = 1.5s, a = 2.5s, a = 3.0s, or a = 3.5s.

[0039] It should be noted that the value of b is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, b = 1s, or b = 1.5s, or b = 2.5s, or b = 3.0s, or b = 3.5s, or b = 4.0s, or b = 4.5s, or b = 5.5s, or b = 6.0s, or b = 6.5s, or b = 7.0s, or b = 7.5s.

[0040] In this embodiment, the control module is electrically connected to the backflushing device. After the control module activates the control tube valve 60, it also activates the backflushing device. This linkage control mechanism between the control module and the backflushing device ensures the timeliness and effectiveness of the backflushing operation, further improving the automation level of the delivery tank.

[0041] Optionally, the backflushing device includes a fan, with the fan outlet facing the first end of the sampling pipe 30. In this way, the fan, acting as a backflushing device, can provide a stable airflow, effectively removing residual samples from the sampling pipe 30, while reducing the complexity and maintenance costs of the backflushing device.

[0042] In this embodiment, a zinc layer is plated on the outer surface of the sampling pipe 30. This makes the sampling pipe 30 a galvanized pipe, enhancing its corrosion resistance, extending its service life, and reducing maintenance costs. Simultaneously, the corrosion-resistant design of the zinc layer effectively protects the sampling pipe 30 from corrosive materials, extending its service life and reducing maintenance and replacement costs caused by pipe corrosion.

[0043] In this embodiment, the inner diameter of the branch pipe 50 is smaller than the inner diameter of the sampling pipe 30. This inner diameter design of the branch pipe 50 improves the sealing effect of the bladder valve 60, reduces leakage, and simultaneously generates a stronger airflow or liquid flow impact force during backflushing, thus improving backflushing efficiency.

[0044] In this embodiment, the sampling pipe 30 is 20cm long.

[0045] In this embodiment, by installing a control valve 40 and a backflushing device on the sampling pipe 30, the backflushing device can blow the residual sample in the sampling pipe 30 back to the conveying pipe 20 after the control valve 40 is closed. The backflushing function of the device can also prevent material blockage, effectively avoiding sample residue and contamination in the sampling pipe 30, ensuring sample purity and conveying efficiency. Furthermore, the combined use of a timing device and a control module enables automated control of the backflushing process, improving operational convenience and system intelligence. The zinc layer and the design of the branch pipe inner diameter further enhance the stability and reliability of the delivery tank, reduce maintenance costs, and improve the effectiveness and benefits in practical applications.

[0046] This application also provides a mill (not shown) including the aforementioned feeding tank.

[0047] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0048] The sending tank includes a sending tank body, a conveying pipeline, a sampling pipeline, a control valve, and a backflushing device. The conveying pipeline is connected to the sending tank body. The control valve is installed on the sampling pipeline to control the on / off state of the sampling pipeline and / or the sample flow rate or velocity within the sampling pipeline. The backflushing device is installed inside the sampling pipeline or located on one side of the sampling pipeline. In this way, the first end of the sampling pipeline extends into the conveying pipeline and slopes downwards. Through the cooperation of the control valve, the sampling pipeline, and the backflushing device, it replaces the existing method of sampling using an angle seat valve, thereby solving the problem of easy wear of the angle seat valve in the existing mill sending tank due to the large sample volume and frequent sampling. When material sampling is required, the control valve is opened, and the material flows along the pipe wall of the sampling pipeline under its own weight, allowing personnel to take samples. After sampling is completed, the control valve is closed. When the control valve is in the closed state, the backflushing device blows air or sprays liquid in a preset direction, causing the sample buffered in the sampling pipeline to flow back into the conveying pipeline through the first end, thus avoiding material waste.
