Description

Technical Field

[0001] This utility model relates to the field of conveyor roller technology, specifically a heating device for a coal conveyor roller. Background Technology

[0002] Coal conveyors are a type of material conveying equipment widely used in the coal industry. They are mainly used to transport coal from one place to another to achieve continuous and efficient coal transportation. The conveyor rollers are an important component of belt conveyors, with functions such as driving, tensioning, and redirection.

[0003] In existing coal conveyor rollers, during use, especially in northern winters when temperatures are low, the surface temperature of both the rollers and the conveyor belt is low, leading to coal sticking and freezing. Furthermore, the low conveyor belt temperature causes it to harden, resulting in accelerated wear. This makes it difficult to use rolling heating to heat the conveyor belt. Therefore, we propose a heating device for the rollers of a coal conveyor. Utility Model Content

[0004] The purpose of this utility model is to provide a heating device for the drum of a coal conveyor, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heating device for a coal conveyor drum, comprising a hot water tank and a drum, wherein a water pump is fixedly installed on one side of the top of the hot water tank, and one end of the water pump is connected to a first conduit, the outer end of the first conduit being connected to the lower side of one side wall of the hot water tank;

[0006] The other end of the water pump is fixedly connected to a second conduit, and both ends of the roller are fixedly connected to rotary joints. The outer end of the second conduit is connected to one of the rotary joints, and the outer end of the other rotary joint is connected to the top of the hot water tank through a third conduit.

[0007] By adopting the above technical solution, the roller is used to drive the conveyor belt. Hot water is drawn from the hot water tank by a water pump, and then introduced into the inner cavity of the roller through the second conduit. Then it flows back into the hot water tank through the roller, thereby heating the roller with circulating hot water. The roller can also transfer heat to the conveyor belt, thereby indirectly heating the conveyor belt. This makes the conveyor belt warm and soften, which helps to avoid coal sticking and freezing. It also helps to avoid the situation where low temperature aggravates the wear of the conveyor belt.

[0008] In a preferred embodiment of the present invention, a plurality of evenly distributed electric heating tubes are fixed at the bottom of the inner cavity of the hot water tank, and a temperature sensor is fixed on the side wall of the inner cavity of the hot water tank.

[0009] By adopting the above technical solution, the temperature sensor can detect the water temperature in the hot water tank. Both the temperature sensor and the electric heating element are connected to the industrial control computer, which then controls the electric heating element to heat the water, thereby achieving accurate control of the hot water temperature and ensuring sufficient temperature.

[0010] In a preferred embodiment of this utility model, the inner cavity of the roller is provided with a fixing rod, both ends of which are fixedly connected to the inner wall of the roller via connecting rods. The outer wall of the fixing rod is fixed with a plurality of evenly distributed semicircular blocks, and the inner wall of the roller is provided with a plurality of evenly distributed grooves.

[0011] By adopting the above technical solution, the semi-circular block allows hot water in the middle of the drum cavity to impact the semi-circular block when it enters the drum cavity, causing it to diffuse outwards. This allows the hot water in the middle area to mix with the hot water in the outer area during the heat exchange process, thus improving the hot water utilization rate. Furthermore, the multiple evenly distributed grooves on the inner wall of the drum increase the contact area with the hot water, thereby improving the heat exchange effect.

[0012] In a preferred embodiment of this utility model, the hot water tank has a hole on the top, and an end cap is detachably fixed inside the hole.

[0013] By adopting the above technical solution, the end cap can be disassembled, thus facilitating water replenishment.

[0014] In a preferred embodiment of this utility model, a gear is fixedly connected to one end of the roller.

[0015] By adopting the above technical solution, the gears are designed to connect with the transmission system inside the conveyor, thereby driving the drum to rotate.

[0016] In a preferred embodiment of this utility model, mounting plates are fixedly installed on both sides of the two side walls of the hot water tank.

[0017] By adopting the above technical solution, the installation plate facilitates the overall installation and fixation of the device.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The present application provides a heating device for a coal conveyor drum. Hot water is drawn from a hot water tank by a water pump and introduced into the drum to heat it. The drum can then transfer heat to the conveyor belt, thereby indirectly heating the conveyor belt. This process warms and softens the conveyor belt, which helps to prevent coal from sticking or freezing. It also helps to prevent low temperatures from exacerbating wear on the conveyor belt.

[0020] When hot water enters the inner cavity of the drum, the hot water in the middle of the inner cavity will impact the semi-circular block and then diffuse outward. This allows the hot water in the middle area to mix with the hot water in the outer area during the heat exchange process, which helps to improve the utilization rate of hot water.

[0021] The inner wall of the drum has multiple evenly distributed grooves, which helps to increase the contact area with hot water and thus improve the heat exchange effect. Attached Figure Description

[0029] Please see Figure 1-3 This utility model provides a technical solution: a heating device for a coal conveyor drum, including a hot water tank 1 and a drum 2. A water pump 11 is fixedly installed on one side of the top of the hot water tank 1. One end of the water pump 11 is connected to a first conduit 12. The outer end of the first conduit 12 is connected to the lower side of one side wall of the hot water tank 1.

[0030] The other end of the water pump 11 is fixedly connected to the second conduit 13, and both ends of the roller 2 are fixedly connected to the rotary joints 21. The outer end of the second conduit 13 is connected to one of the rotary joints 21, and the outer end of the other rotary joint 21 is connected to the top of the hot water tank 1 through the third conduit 14.

[0031] It should be understood that in actual use, the roller 2 is used to drive the conveyor belt. The water pump 11 draws hot water from the hot water tank 1, then introduces it into the inner cavity of the roller 2 through the second conduit 13, and then flows back into the hot water tank 1 through the roller 2. In this way, the circulating hot water heats the roller 2, and the roller 2 can transfer heat to the conveyor belt, thereby indirectly heating the conveyor belt. This makes the conveyor belt warm and soften, which helps to avoid coal sticking and freezing, and also helps to avoid the situation where the low temperature aggravates the wear of the conveyor belt.

[0032] Furthermore, mounting plates 15 are fixedly installed on both sides of the hot water tank 1. The installation plates 15 facilitate the overall installation and fixation of the device.

[0033] Furthermore, a gear 22 is fixedly connected to one end of the roller 2. The gear 22 is designed to connect with the transmission system inside the conveyor, thereby driving the roller 2 to rotate.

[0034] It is worth mentioning that the top of the hot water tank 1 has a hole, and an end cap 16 is detachably fixed inside the hole. The end cap 16 is designed to be detachable, making it convenient to add water.

[0035] like Figure 1 and 2 As shown; multiple evenly distributed electric heating tubes 17 are fixed at the bottom of the inner cavity of the hot water tank 1, and a temperature sensor 18 is fixed on the side wall of the inner cavity of the hot water tank 1.

[0036] As we understand it, the temperature sensor 18 can detect the water temperature in the hot water tank 1, and both the temperature sensor 18 and the electric heating element 17 are connected to the industrial control computer. The industrial control computer can then control the electric heating element 17 to heat the water, thereby accurately controlling the hot water temperature and ensuring that the temperature is sufficient.

[0037] like Figure 1 and 2 As shown; the inner cavity of the roller 2 is provided with a fixing rod 23, both ends of the fixing rod 23 are fixedly connected to the inner wall of the roller 2 through connecting rod 25, and multiple evenly distributed semi-circular blocks 24 are fixed on the outer wall of the fixing rod 23, and multiple evenly distributed grooves 26 are opened on the inner wall of the roller 2.

[0038] It should be understood that during the heating process of drum 2, when hot water passes through the inner cavity of drum 2, the water in contact with the inner wall of the drum is only on the outer side of the water flow, and the middle area of ​​the hot water has less residual heat exchange.

[0039] By setting the semicircular block 24, when hot water enters the inner cavity of the drum 2, the hot water in the middle of the inner cavity of the drum 2 will impact the semicircular block 24 and diffuse outward. In this way, the hot water in the middle area can be mixed with the hot water in the outer area during the heat exchange process, which is beneficial to improving the hot water utilization rate.

[0040] Furthermore, the inner wall of the drum 2 has multiple evenly distributed grooves 26, which helps to increase the contact area with hot water and thus improve the heat exchange effect.

[0041] Furthermore, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0042] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the specific embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
