Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of slag cooling equipment, specifically to a slag temperature cooling hopper. Background Technology
[0002] The slag produced from municipal solid waste incineration needs to be transported to the next process. The high-temperature slag can melt the equipment during the transport process, causing damage.
[0003] Therefore, it is necessary to cool the high-temperature slag. In the existing technology, the high-temperature slag is usually cooled by a slag cooler. However, the receiving hopper and channel between the slag cooler and the incinerator do not have a cooling function, which can easily lead to melting and damage at the channel.
[0004] Therefore, designing a cooling function at the receiving hopper can assist in cooling down, improve cooling efficiency, and prevent damage to the receiving hopper and channel.
[0005] Moreover, traditional cooling structures can only cool the slag through indirect heat conduction, and can only contact the outside of the slag, resulting in a limited contact area and low cooling efficiency. Utility Model Content
[0006] To address the shortcomings of the aforementioned technologies, this invention provides a slag temperature cooling hopper.
[0007] The technical solution of this utility model is as follows: a slag temperature cooling hopper, the hopper including a shell, several cooling shafts, a cooling circulation pump, and a hydraulic drive device. The shell is provided with a feed inlet, a material passage, and a discharge outlet. A water-cooling chamber is provided inside the shell. The shell is provided with several shaft holes that extend from the outside of the shell to the material passage. A sealing baffle wall is provided inside the water-cooling chamber to surround each shaft hole. The sealing baffle wall is isolated from the water-cooling chamber.
[0008] The plurality of cooling shaft components are inserted into each shaft hole for sliding engagement. Each cooling shaft component includes an insertion end and a hinge end connected to the hydraulic drive device. The cooling shaft component has a flow cavity in the center and a first water inlet and a first water outlet are radially arranged in the area corresponding to the sealing baffle between the two ends. The sealing baffle is provided with a second water inlet and a second water outlet that communicate with the water cooling cavity. A flexible hose is provided between the first water inlet and the second water inlet, and between the first water outlet and the second water outlet.
[0009] The hinge ends of each cooling shaft are respectively linked with the hydraulic drive device. The hydraulic drive device drives the cooling shaft to reciprocate in and out of the material passage along the shaft hole. The water cooling chamber is provided with a third water inlet and a third water outlet, and is connected to the cooling circulation pump. The cooling circulation pump injects cooling water into the plant area, and the cooling water in the water cooling chamber flows to the plant cooling tower.
[0010] A further feature of this invention is that the outer side of the housing is provided with several reinforcing holes that extend into the cooling chamber. Each reinforcing hole is welded with a reinforcing support member. One end of the reinforcing support member rests against the inner wall of the water-cooled chamber near the material passage, and the other end extends out of the reinforcing hole and is sealed and welded to the reinforcing hole.
[0011] A further feature of this invention is that the reinforcing support is a tubular component.
[0012] A further feature of this invention is that a sliding bushing is provided at the shaft hole to make axial sliding fit with the cooling shaft.
[0013] The beneficial effects of this invention are as follows: By setting a cooling structure at the receiving hopper, the slag is cooled, preventing damage to the conveying equipment. The cooling hopper is equipped with a cooling shaft that can axially enter and exit the material passage, and a sealed baffle is designed to separate the water-cooled chamber from the moving space of the cooling shaft, preventing cooling water from flowing into the material passage through the shaft hole.
[0014] The water-cooled chamber is connected by flexible hoses between the first and second water inlets and between the first and second water outlets. The cooling water in the water-cooled chamber is guided into the cooling shaft for neutralization and discharge. In this way, in addition to the overall cooling of the shell by the water-cooled chamber, the cooling shaft can also be inserted into the material passage to increase the contact area and conduct heat and cool the interior of the passing slag over a larger area. The flexible hose connects the cooling water without affecting the movement of the cooling shaft, and can deform with it within the sealed baffle wall.
[0015] The hydraulic equipment can periodically and alternately pull each cooling shaft out of the material passage one by one. The cooled shaft can be cooled down quickly and then re-enter the material passage to replace it, thereby enhancing the cooling effect and avoiding the problem of reduced cooling effect caused by continuous contact between the cooling shaft and the slag.
[0016] The tubular reinforcing support not only strengthens the overall strength of the hopper after the water-cooling chamber is installed, but also allows for auxiliary cooling via external airflow through the central hole facing the outside of the shell. Attached Figure Description

[0026] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-4 As shown,
[0027] A slag temperature cooling hopper includes a shell 1, several cooling shafts 2, a cooling circulation pump, and a hydraulic drive device. The shell 1 is provided with a feed inlet 11, a material passage 12, and a discharge outlet 13. A water-cooling chamber 14 is provided inside the shell 1. The shell 1 is provided with several shaft holes 15 that extend from the outside of the shell 1 to the material passage 12. A sealing baffle 3 is provided inside the water-cooling chamber 14, surrounding each shaft hole 15. The sealing baffle 3 is isolated from the water-cooling chamber 14.
[0028] The cooling shaft 2 is inserted into each shaft hole 15 for sliding engagement. The cooling shaft 2 includes an insertion end and a hinge end 21 connected to the hydraulic drive device. The cooling shaft 2 has a flow cavity 22 in the center and a first water inlet 23 and a first water outlet 24 radially arranged between the two ends in the area corresponding to the sealing baffle 3. The sealing baffle 3 is provided with a second water inlet 31 and a second water outlet 32 communicating with the water cooling cavity 14. A flexible hose 33 is provided between the first water inlet 23 and the second water inlet 31 and between the first water outlet 24 and the second water outlet 32.
[0029] The hinge ends 21 of each cooling shaft 2 are respectively linked with the hydraulic drive device. The hydraulic drive device drives the cooling shaft 2 to reciprocate in and out of the material passage 12 along the shaft hole 15. The water cooling chamber 14 is provided with a third water inlet 16 and a third water outlet 17, and is connected to the cooling circulation pump. The cooling circulation pump injects cooling water into the plant area, and the cooling water in the water cooling chamber 14 flows to the plant cooling tower.
[0030] The outer side of the housing 1 is provided with a number of reinforcing holes 18 that penetrate into the cooling cavity. Each reinforcing hole 18 is welded with a reinforcing support 4. One end of the reinforcing support 4 abuts against the inner wall of the water-cooled cavity 14 near the material passage 12, and the other end passes through the reinforcing hole 18 and is sealed and welded to the reinforcing hole 18.
[0031] The reinforcing support 4 is a tubular component.
[0032] A sliding bushing is provided at the shaft hole 15 to make axial sliding fit with the cooling shaft 2.
[0033] A cooling structure is installed at the receiving hopper to help cool the slag and prevent damage to the conveying equipment. The cooling hopper is equipped with a cooling shaft 2 that can enter and exit the material passage 12 axially, and a sealing baffle 3 is designed to separate the water-cooled chamber 14 from the moving space of the cooling shaft 2. The water-cooled chamber 14 is connected by a flexible hose 33 between the first water inlet 23 and the second water inlet 31 and between the first water outlet 24 and the second water outlet 32, so that the cooling water in the water-cooled chamber 14 is introduced into the cooling shaft 2 for neutralization and discharge. In this way, in addition to the water-cooled chamber 14 cooling the shell 1 as a whole, the cooling shaft 2 can also be inserted into the material passage 12 to conduct heat and cool the interior of the passing slag.
[0034] The hydraulic equipment can periodically and alternately pull each cooling shaft 2 out of the material passage 12 one by one. After the cooling shaft 2 is cooled down, it can re-enter the material passage 12 to replace it, thereby enhancing the cooling effect and avoiding the problem of reduced cooling effect caused by the cooling shaft 2 continuously contacting the slag.
[0035] The tubular reinforcing support 4 can not only strengthen the overall strength of the hopper after the water-cooling chamber 14 is installed, but also use its central hole facing the outside of the shell 1 to provide auxiliary cooling through external air.
