[0002] The mixer is a crucial piece of equipment in the sintering system. Within the mixer, materials are mixed, water is added, quicklime is absorbed, and pellets are formed. When the metal material is wetted and quicklime is absorbed, material easily sticks to the mixer drum. This sticking increases the mixer's filling rate, affecting the mixing and pelletizing effect. Excessive sticking can lead to increased mixer current, higher sintering costs, and a large workload for personnel using pneumatic picks for cleaning. Prolonged downtime inevitably reduces the steel company's profitability; furthermore, the cleaning process poses a significant risk of injury from falling large pieces. Utility Model Content

[0031] Please see Figure 1 and Figure 2 This application provides a mixer 10, including a cylinder 100, a first water inlet pipe (not shown), and a second water inlet pipe 200. The first water inlet pipe is disposed inside the cylinder 100, and its water outlet direction is towards the material lifting surface. The second water inlet pipe 200 is disposed inside the cylinder 100 and includes a water inlet pipe body 210 and a water inlet nozzle 220 disposed on the water inlet pipe body 210. The water inlet nozzle 220 can spray water onto the inner wall of the cylinder 100. The water outlet direction of the water inlet nozzle 220 is opposite to that of the first water inlet pipe.

[0032] The cylinder 100 is the basic component of the mixer 10, used to provide installation and protection for at least other components of the mixer 10, and the materials are mixed evenly within the cylinder 100. The lifting surface is the area where the materials are thrown or turned over. Since the water outlet direction of the first water supply pipe is towards the lifting surface, the materials and water can be fully mixed, ensuring the air permeability of the sintering material layer, thereby ensuring the pelletizing effect.

[0033] The second water inlet pipe 200 includes a water inlet pipe body 210 and a water inlet nozzle 220 connected to the water inlet pipe body 210. The water inlet nozzle 220 can be set at the end of the water inlet pipe body 210. The water inlet nozzle 220 is used to spray water. The end of the water inlet nozzle 220 can reduce the orifice diameter to increase the pressure, so that the water sprayed by the water inlet nozzle 220 forms a water column, thereby improving the flushing effect.

[0034] The water nozzle 220 can spray water onto the inner wall of the cylinder 100, and the water outlet direction of the water nozzle 220 is opposite to the water outlet direction of the first water supply pipe, that is, the water outlet direction of the water nozzle 220 is opposite to the material lifting direction, and can spray water onto the inner wall opposite to the material lifting direction, thereby flushing the inner wall opposite to the material lifting direction to improve the problem of material sticking to the inner wall of the cylinder 100.

[0035] It should be explained that in related technologies, the cylinder 100 is usually equipped with only one water supply pipe facing the lifting surface (i.e., the first water supply pipe in this embodiment) to ensure that the material and water are fully mixed. When the water and material enter the mixer 10 through the lifting surface and are stirred, the viscosity of the water-soaked material will increase, especially the material on the side of the mixer 10 opposite to the lifting direction of the lifting surface. This will cause serious material adhesion on the inner wall of the cylinder 10 opposite to the lifting direction. Therefore, in this embodiment, a second water supply pipe 200 is added so that the water outlet direction of the second water supply pipe 200 is towards the inner wall opposite to the lifting direction of the lifting surface, so as to flush the inner wall on that side and improve the problem of material adhesion on the inner wall of the cylinder 100.

[0036] Therefore, this application mainly describes the structure and installation of the second water inlet pipe 200, while the first water inlet pipe can be the water inlet pipe in the mixer 10 in the related technology, and will not be described in detail here.

[0037] In some embodiments, the second water supply pipe 200 is movable along the axial direction of the cylinder 100.

[0038] The cylinder 100 has an inlet and an outlet. The axial direction of the cylinder 100 is the length direction of the cylinder 100. The second water inlet pipe 200 can move along the axial direction of the cylinder 100, that is, the second water inlet pipe 200 can move back and forth between the inlet and the outlet along the axial direction of the cylinder 100, so as to ensure that the inner wall of each part of the cylinder 100 in the length direction can be flushed as much as possible, thereby improving the flushing effect.

[0039] Please see Figure 1 In some embodiments, the mixer 10 includes a traction rope 300 and a drive assembly 400. The traction rope 300 is movably inserted through the cylinder 100 along the axial direction of the cylinder 100. The water supply pipe 210 is fixedly sleeved on the traction rope 300. The drive assembly 400 is connected to the traction rope 300 for transmission to drive the traction rope 300 to move.

[0040] Since the traction rope 300 is movably inserted through the cylinder 100 along the axial direction of the cylinder 100, the drive assembly 400 is used to drive the traction rope 300 to reciprocate between the inlet and the outlet. Since the water inlet pipe 210 is fixedly sleeved on the traction rope 300, the traction rope 300 can drive the water inlet pipe 210 to reciprocate between the inlet and the outlet along the axial direction of the cylinder 100.

[0041] Please see Figure 1 In some embodiments, the drive assembly 400 includes two drive members 410, which are disposed outside the cylinder 100 and respectively connected to both ends of the traction rope 300.

[0042] Two drive units 410 are respectively connected to both ends of the traction rope 300, that is, the two drive units 410 are respectively set on one side of the feed inlet and one side of the discharge outlet, so as to drive the traction rope 300 to move in the direction from the feed inlet to the discharge outlet, or in the direction from the discharge outlet to the feed inlet. Specifically, the drive unit 410 can be a winch.

[0043] It should be noted that the mixer 10 may also include a control system, which is signal-connected to the two drive units 410 to control the drive units 410, so that the second water supply pipe 200 has two control modes: one is an automatic circulation mode and the other is a fixed-point backwashing mode.

[0044] During normal production, an automatic circulation mode is used. The control system controls two drive components 410 to move the second water supply pipe 200 from the inlet to the outlet according to a set interval, achieving flushing of the inner wall along the length of the cylinder 100. When there is a large amount of material stuck in a certain area, a directional blowing mode is adopted according to the location of the stuck material. The control system controls the two drive components 410 to drive the second water supply pipe 200 to a fixed position to achieve precise cleaning of the stuck material. The control system can automatically record the location of the area with the most stuck material and increase the blowing time at that point during automatic operation to reduce the occurrence of stuck material problems. In addition, the control system can gradually reduce the spraying time of the water supply nozzle 220 each week to reduce the impact on the mixing effect of the mixer 10.

[0045] Please see Figure 1 In some embodiments, the mixer 10 further includes a support frame and two guide wheels 500 mounted on the support frame. The two guide wheels 500 are located outside the cylinder 100 and are respectively located at both ends of the traction rope 300. The traction rope 300 passes around the two guide wheels 500 to guide the movement of the traction rope 300.

[0046] Please see Figure 1 and Figure 3 In some embodiments, the mixer 10 further includes a guide rope 600 and a connector 700. The guide rope 600 is fixedly disposed inside the cylinder 100 along the axial direction of the cylinder 100. One end of the connector 700 is movably connected to the guide rope 600, and the other end is fixedly connected to the water supply pipe 210.

[0047] The guide rope 600 is fixedly installed inside the cylinder 100 along the axial direction of the cylinder 100, that is, the guide rope 600 is arranged parallel to the traction rope 300, and the guide rope 600 can be set above the traction rope 300. Since one end of the connector 700 is movably connected to the guide rope 600 and the other end is fixedly connected to the water filling pipe 210, when the water filling pipe 210 moves with the traction rope 300, the connector 700 also moves along the guide rope 600, thereby providing guidance for the movement of the water filling pipe 210 and realizing the stable installation of the traction rope 300 and the second water filling pipe 200 inside the cylinder 100.

[0048] Specifically, both the guide rope 600 and the traction rope 300 can be steel wire ropes. The connector 700 includes a connecting ring 710 and a connecting rod 720 connected together. The connecting ring 710 is movably sleeved on the guide rope 600, and the connecting rod 720 is fixedly connected to the water supply pipe body 210.

[0049] Please see Figure 4 In some embodiments, the mixer 10 further includes a protective cover 800, which is installed on the first water supply pipe and covers the second water supply pipe 200. The length of the protective cover 800 is greater than or equal to the range of motion of the second water supply pipe 200.

[0050] The first water inlet pipe is fixedly installed inside the cylinder 100, and the protective cover 800 is installed on the first water inlet pipe, thus fixing the protective cover 800 as well. The first water inlet pipe and the second water inlet pipe 200 can be arranged parallel and spaced apart. Therefore, the protective cover 800 installed on the first water inlet pipe can also cover the second water inlet pipe 200 at the same time. In this way, when the inner wall of the cylinder 100 is washed away by material, the protective cover 800 can prevent the material from falling onto the second water inlet pipe 200 and affecting the water spraying function of the second water inlet pipe 200.

[0051] Specifically, the protective cover 800 includes two protective plates 810 arranged at an included angle, with the opening of the protective cover 800 facing the second water supply pipe 200. That is, the two protective plates 810 are arranged at an angle, which can guide the material falling on the protective plates 810 and prevent the material from accumulating on the protective cover 800.

[0052] In some embodiments, the mixer 10 further includes a control valve and a water supply pipe disposed outside the cylinder 100, wherein both the first water supply pipe and the second water supply pipe 200 are connected to the water supply pipe, and the control valve is disposed on the second water supply pipe 200.

[0053] The water supply pipe is connected to a water source to supply water to the first and second water supply pipes 200. Since the control valve is located in the second water supply pipe 200, it can be closed when flushing is not required, thus minimizing the risk of low pressure due to reduced water flow in the first water supply pipe. Specifically, the control valve can be a solenoid valve.

[0054] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0055] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
