Description

TECHNICAL FIELD

[0001] The utility model relates to a structure of increasing wear resistance of drying tower. BACKGROUND

[0002] The drying tower body generally has a grain inlet pipeline and a grain outlet hopper. In the process of grain inlet and outlet, a large amount of grain gathered in a short time continuously impacts and rubs the plate, which causes the plate to be worn out. Moreover, the drying tower is installed outdoors, and even if the zinc layer on the surface of the galvanized plate is damaged after a long time, rust will be generated, which will accelerate the damage speed of the parts. The feed pipe is not convenient to replace and repair in the air. Rust is taken away in the process of grain flow, which affects the quality of grain drying. SUMMARY

[0003] The utility model discloses a structure of increasing wear resistance of drying tower.

[0004] A structure of increasing wear resistance of drying tower, including feed pipe, discharge pipe, the feed pipe and discharge pipe all are hollow structure, and the contact surface of the inner side wall in it with grain all is equipped with anti -wear board, the material of anti -wear board is PE material quality.

[0005] Further, the feed pipe is a rectangular parallelepiped structure formed by splicing galvanized plate material, and the discharge pipe is a conical structure formed by splicing galvanized plate material.

[0006] Further, the anti -wear board is fixedly connected with the inner side wall of the feed pipe or the discharge pipe through the countersunk head bolt.

[0007] Further, the anti -wear board surface is further provided with the micro convex wear texture, and the wear texture can further enhance the sliding property between the anti -wear board and the grain particles, reduce direct friction, thereby further improving the wear resistance.

[0008] Further, the connecting part of the feed pipe and the discharge pipe is designed with a reinforcing ring made of high-strength stainless steel to enhance the structural strength of the connecting part and prevent deformation or damage caused by long-term bearing of grain flow pressure.

[0009] Further, the rectangular parallelepiped structure of the feed pipe is designed with a round corner transition at each corner to reduce direct impact of the grain on the corner during flow and reduce the risk of grain blockage and improve overall smoothness.

[0010] Further, the head of the countersunk head bolt is embedded in the anti -wear board and is treated specially to ensure the surface flatness and avoid forming an obstacle point for grain flow, and an anti -corrosion coating is used to protect the bolt and prolong its service life.

[0011] Further, on the outside of the feed pipe and the discharge pipe, a heat preservation layer is arranged, which is made of high-temperature-resistant and fireproof material, so as to reduce heat loss during drying, improve energy utilization efficiency, and protect the internal structure from external temperature changes.

[0012] Further, an adjustable gate device is arranged at the bottom outlet of the conical structure of the discharge pipe, which is controlled by electricity or gas to adjust the opening and closing degree, so as to adjust the flow of grain according to actual needs, and realize more flexible drying operation control.

[0013] Beneficial effects: Compared with the prior art, the smoothness of the contact surface with the grain is improved by adding the PE material wear plate. The wear plate made of polyethylene material has good self-lubricating property, smooth surface and low friction coefficient, which can make the grain flow in and out faster, thereby improving the efficiency of the drying tower in completing grain drying. The polyethylene wear plate of the tower body has good impact resistance, and under the condition that a large amount of grain impacts the inner wall of the feed pipe and the discharge hopper along the grain flow direction in a short time during grain feeding and discharging, the upper feed wear plate and the lower discharge wear plate are not cracked and deformed, can absorb impact energy, and reduce the damage of the grain to the galvanized shell. In this way, not only the service life of the feed pipe and the discharge pipe of the drying tower is effectively prolonged, but also the maintenance cost is reduced. BRIEF DESCRIPTION OF DRAWINGS

[0019] In order to deepen the understanding of the present application, the present application will be further described in combination with examples and drawings, and the examples are only used to explain the present application and do not constitute a limitation on the protection scope of the present application.

[0020] As shown in the figure, the feed pipe 1, the discharge pipe 2, the wear plate 3, and the countersunk bolt 4 are shown. Figs. 1-4

[0021] ​The utility model relates to a structure for increasing the wear resistance of a drying tower, comprising a feed pipe 1 and a discharge pipe 2, both of which are hollow structures, and the inner side walls of both are provided with wear-resistant plates 3 on the contact surface with grain, the material of the wear-resistant plates 3 being PE (ultra-high molecular weight polyethylene), and it should be noted that the thickness of the PE plates used in the protective plates in this structure is 6 mm.

[0022] In this embodiment, the feed pipe 1 is a cuboid structure formed by splicing galvanized sheet metal, and the discharge pipe 2 is a conical structure formed by splicing galvanized sheet metal.

[0023] In this embodiment, the wear-resistant plates 3 are fixedly connected to the inner side walls of the feed pipe 1 or the discharge pipe 2 by means of countersunk head bolts 4.

[0024] In this embodiment, the surface of the wear-resistant plates is also provided with a micro-convex wear-resistant texture, which can further enhance the sliding property between the wear-resistant plates and the grain particles, reduce direct friction, and thus further improve the wear resistance.

[0025] In this embodiment, a reinforcing ring made of high-strength stainless steel is designed at the connection between the feed pipe and the discharge pipe, to enhance the structural strength of the connection part and prevent deformation or damage due to long-term bearing of the flow pressure of grain.

[0026] In this embodiment, the edges and corners of the cuboid structure of the feed pipe are designed with rounded transitions, to reduce the direct impact of grain on the edges and corners during flow and to reduce the risk of grain blockage and improve overall flow.

[0027] In this embodiment, the head of the countersunk head bolt is embedded in the wear-resistant plate and is specially treated to ensure a smooth surface and avoid forming an obstacle point for grain flow, and an anti-corrosion coating is used to protect the bolt and prolong its service life.

[0028] In this embodiment, a heat preservation layer is also provided on the outside of the feed pipe and the discharge pipe, which is made of a material with good high-temperature resistance and fire resistance, to reduce heat loss during drying, improve energy utilization efficiency, and protect the internal structure from the influence of external temperature changes.

[0029] In this embodiment, an adjustable gate device is provided at the outlet of the conical structure of the discharge pipe, which is controlled by an electric or pneumatic method to adjust the opening and closing degree, so as to adjust the flow of grain according to actual needs and realize more flexible control of drying operation.

[0030] Usage: In practical application, the grain enters the drying tower body from the top layer feeding pipe and is discharged from the discharge hopper (3, 4), and during the process from the beginning to the completion of the grain drying, because the polyethylene material wear plate has good self-lubricating property, smooth surface and low friction coefficient, the grain can flow in and out more quickly, which improves the efficiency of the drying tower in completing the grain drying. The polyethylene wear plate of the tower body has good impact resistance, and under the condition that a large amount of grain impacts the inner wall of the feeding pipe and the discharge hopper along the grain flow direction in a short time during the grain feeding and discharging, the upper feeding wear plate and the lower discharge wear plate are not cracked and deformed, and can absorb impact energy and reduce the damage of the grain to the galvanized shell.

[0031] In this way, not only the service life of the feeding and discharging pipes of the drying tower is effectively prolonged, but also the maintenance cost is reduced. The drying tower is generally installed outdoors due to its large size, and rain and wind can erode the surface shell and further cause corrosion and rust, thereby reducing the service life of the feeding and discharging pipes. The polyethylene wear plate has relatively stable chemical stability and is not damaged in acid and alkali corrosion media for a long time.

[0032] Therefore, the polyethylene wear plate is suitable for the occasions of the feeding and discharging pipes of the drying tower requiring wear resistance, impact resistance and self-lubrication. The self-weight of the polyethylene wear plate is very light, and it is easy to process and install, and the price of the plate material is not much different from that of the medium-thick galvanized plate. Therefore, the thin galvanized material is selected as the appearance shell and the polyethylene wear plate with a thickness of 6mm is laid thereon, and compared with other materials, the polyethylene wear plate also has small environmental burden and is considered as a sustainable production material, which is relatively environmentally friendly.

[0033] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
