[0002] In existing coke transportation systems, three-way chutes are widely used to flexibly control material flow. Using gravity, they guide materials from a single point to multiple directions, achieving efficient material distribution. However, in winter, when temperatures drop below zero, if moisture is encountered in coal or coke (coke foam) during transportation, the moisture will condense inside the chute, hindering the flow of material and causing ice to form on the chute gates, particularly the three-way gates.

[0003] Existing technologies generally use mechanical means to clear blockages or thaw, such as manually using hot water or hot air for thawing. Although this can solve local problems to a certain extent, it often has the disadvantages of low efficiency and high labor intensity. Under extreme weather conditions, the current thawing measures may not be able to restore material flow in a timely manner, causing production line stagnation and delayed delivery time, thereby causing economic losses.

DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as Figure 1-4 As shown, a heating device for preventing and thawing a three-way chute includes a three-way chute 1. The three-way chute 1 is used for the flow and distribution of materials, guiding the materials in different directions. A first steam pipe 4 is provided at the inlet end of the three-way chute 1, and a second steam pipe 5 and a third steam pipe 6 are provided at the two outlet ends of the three-way chute 1. The first steam pipe 4 is connected to the second steam pipe 5 and the third steam pipe 6 respectively. The first steam pipe 4 conducts steam to the second steam pipe 5 and the third steam pipe 6. At the same time, the first steam pipe 4 can heat and warm the inlet end of the three-way chute 1 to prevent ice from forming inside the three-way chute 1.

[0025] The second and third steam pipes 5 and 6 surround the outlet of the tee chute 1, transferring heat to prevent internal ice formation. This ensures uniform heating across all sections of the tee chute 1, enhancing overall antifreeze effectiveness. The first, second, and third steam pipes 4, 5, and 6 are arranged in a coil 10 around the outer wall of the tee chute 1. The coil 10 evenly distributes steam across the outer wall of the tee chute 1. This disc-like layout increases the heat exchange area and improves heating efficiency.

[0026] A steam inlet pipe 2 is connected to one side of the first steam pipe 4. The steam inlet pipe 2 introduces steam into the first steam pipe 4. A steam reserve pipe 3 is provided on the steam inlet pipe 2. The steam reserve pipe 3 serves as a backup supply channel for steam to ensure continued heating when the steam inlet pipe 2 is blocked. For example, after the steam inlet pipe 2 is frozen, steam can be blown from the steam reserve pipe 3 to the frozen position to quickly thaw it.

[0027] A steam outlet pipe 11 is provided at the bottom of each of the second steam pipe 5 and the third steam pipe 6 to discharge the steam. A fan-shaped gate plate 7 is provided on one side of the two outlet ends of the three-way chute 1 to control the flow of materials in the three-way chute 1. It has high flexibility and helps to achieve accurate distribution of materials.

[0028] The following is a detailed description of the design of the above key components:

[0029] The steam outlet pipe 11 is connected to a drain pipe 12 , which collects condensed water to prevent ice formation caused by accumulated water. A drain valve 13 is provided on the drain pipe 12 , and the drain valve 13 controls the opening and closing of the drain pipe 12 .

[0030] The fan-shaped gate plate 7 is connected to a hydraulic rod 8, and the end of the hydraulic rod 8 is connected to a hydraulic cylinder 9. The hydraulic rod 8 and the hydraulic cylinder 9 form a hydraulic device, and the opening and closing state of the fan-shaped gate plate 7 is adjusted by the hydraulic device.

[0031] The first steam pipe 4 adopts a DN32 pipe. The first steam pipe 4 serves as the main steam transmission channel and has a large heat supply, ensuring that the steam is quickly and efficiently transmitted to the second steam pipe 5 and the third steam pipe 6. The use of larger diameter pipes can reduce the resistance to steam flow and improve transmission efficiency. The second steam pipe 5 and the third steam pipe 6 both adopt DN25 pipes. The second steam pipe 5 and the third steam pipe 6 respectively use steam to warm different discharge ports of the three-way chute 1 to achieve uniform heating, providing a good heating effect, which is sufficient to meet antifreeze requirements.

[0032] The steam inlet pipe 2 is provided with a main stop valve and a safety valve. The main stop valve controls the steam flow entering the steam inlet pipe 2 and is easy to open and close, convenient for maintenance and overhaul. The safety valve prevents accidents in the steam pipeline due to overpressure, ensuring safety.

[0033] The steam reserve pipe 3 is set behind the main stop valve of the steam inlet pipe 2. The steam reserve pipe 3 provides a backup steam source to be used in case of main source failure. A ball valve or stop valve is set on the steam reserve pipe 3. The ball valve or stop valve is used to control the flow of the backup steam, which is convenient for switching or closing in different situations.

[0034] The first steam pipe 4 is configured as two pipelines with a total of two inlets and two outlets. The two inlets are respectively connected to the steam inlet pipe 2. A separately controlled ball valve is provided in front of each inlet. The two outlets are respectively connected to the second steam pipe 5 and the third steam pipe 6. The ball valves provided in front of each inlet are convenient for separately controlling the flow direction and flow of steam, so that the operator can flexibly adjust the heating according to actual needs. The advantage of branch control is that the steam can be cut off separately during maintenance without affecting the insulation and antifreeze of the other side, and it is easier to ensure smooth steam flow with two steam routes than with one steam route.

[0035] In addition, the steam pipe only needs to be set up to the lower edge of the three-way chute 1. After the gate is closed, the material flow under the gate flows through the material space, and there is no material and it will not freeze. If the lining plate of the chute is concave and easy to accumulate material, the length of the steam pipe can be extended.

[0036] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology. It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
