Description

Technical Field

[0001] The utility model relates to the technical field of slag treatment, in particular to a device for treating phosphate slag. Background Art

[0002] Phosphate slag is the waste residue selected after phosphate ore mining. Since the waste residue contains phosphorus, fluorine, organic impurities, etc., the phosphate slag is activated to stimulate its potential activity, and after treatment, it can be used to produce related materials such as cement. During the treatment, it is generally necessary to crush it first to obtain phosphate slag with a relatively uniform particle size. Since some wet phosphate slag will have some remaining materials adhering to the crushing wheel during direct crushing, the crushing efficiency will be reduced. Therefore, the phosphate slag is often dried by drying or other methods first. However, such treatment has the following defects: 1. When the phosphate slag is crushed, the heat is transferred to the crushing wheel, and the high temperature will exacerbate the material fatigue and lubrication failure of the crushing wheel, thus reducing its service life. Secondly, the high temperature is likely to affect the motor driving its rotation, resulting in heat inside the motor and increasing the probability of failure; 2. Dust is easily generated after crushing, which will affect the surrounding environment and the safety of workers. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of this utility model.

[0024] Please refer to Figures 1-4, the utility model discloses a phosphorous slag treatment device, which includes a treatment housing 1. A plurality of crushing wheels 2 are rotatably installed in the treatment housing 1. A power mechanism for driving each crushing wheel 2 to rotate is arranged on the treatment housing 1. Each crushing wheel 2 rotates to crush the slag entering the treatment housing 1.

[0025] In one embodiment, the crushing wheel 2 includes a wheel body 21 with a hollow interior. A circulating cooling mechanism 5 is arranged on the treatment housing 1. When the circulating cooling mechanism 5 operates, a heat exchange medium is injected into the wheel body 21 from one end thereof, and the heat exchange medium is transmitted to the circulating cooling mechanism 5 from the other end of the wheel body 21 to form a cycle, and is used for cooling the heat exchange medium. A dust reduction mechanism 6 is arranged on the outer wall of the treatment housing 1. The dust reduction mechanism 6 is located at the bottom of the crushing wheel 2 and is used for dust reduction treatment of the slag outside the treatment housing 1.

[0026] In specific implementation, the phosphorous slag is put into the treatment housing 1. The power mechanism drives each crushing wheel 2 to rotate relative to each other to crush the slag. During this process, the circulating cooling mechanism 5 works, so that the heat exchange medium inside it reciprocally circulates inside the wheel body 21 and at the circulating cooling mechanism 5, and at the same time cools the circulating heat exchange medium, so that the wheel body 21 can always be maintained within a suitable temperature range during long-term operation. And in actual situations, a conveyor belt is arranged at the bottom of the device. The crushed phosphorous slag falls onto the conveyor belt and is conveyed to the corresponding position through the conveyor belt. During this process, the dust reduction mechanism 6 also works simultaneously to perform dust reduction treatment on the crushed slag outside the treatment housing 1 for convenient actual use.

[0027] Preferably, the heat exchange medium is water.

[0028] It can be understood that since the dust reduction mechanism 6 is located outside the treatment housing 1, it will not affect the crushing wheels 2 inside the treatment housing 1 when performing dust reduction treatment on the phosphorous slag.

[0029] In one embodiment, the treatment housing 1 includes a housing body 11. An inlet 12 and an outlet 13 are respectively formed at the top and bottom of the housing body 11. Each crushing wheel 2 is located between the inlet 12 and the outlet 13.

[0030] In specific implementation, the slag enters the housing body 11 from the inlet 12, is crushed by the crushing wheels 2, and is discharged from the outlet 13 after the treatment is completed.

[0031] In one embodiment, the crushing wheel 2 further includes mounting sleeves 22 rotatably installed on both sides of the wheel body 21 and in dynamic sealing cooperation therewith. Each mounting sleeve 22 is provided with a transmission disk 23 located inside the wheel body 21 and having a hollow interior. Each transmission disk 23 communicates with the corresponding mounting sleeve 22. A connector 24 communicating with the interior is installed on the lower side of each transmission disk 23. An interface for docking with the circulating cooling mechanism 5 is also installed on the mounting sleeve 22. In the working state, the mounting sleeve 22 does not rotate.

[0032] In specific implementation, when the circulating cooling mechanism 5 is operating, a heat exchange medium is injected into the mounting sleeve 22 on one side of the wheel body 21. The heat exchange medium sequentially passes through the corresponding transmission disk 23 and the connector 24 and is injected into the wheel body 21. When the circulating cooling mechanism 5 continues to work, the heat exchange medium will flow back into the circulating cooling mechanism 5 from the transmission disk 23, the connector 24, and the mounting sleeve 22 on the other side of the wheel body 21, thus completing the cycle. At the same time, since the connector 24 rotates continuously during operation, while the mounting sleeve 22 and the transmission disk 23 do not move, the connector 24 is always located on the lower side inside the wheel body 21, facilitating the effective conduction of the heat exchange medium.

[0033] In one embodiment, the circulating cooling mechanism 5 includes a conduction table 51 installed on the processing housing 1. Each conduction table 51 has a hollow interior and communicates with the corresponding mounting sleeve 22. Each conduction table 51 is provided with a transmission pipe 52 communicating therewith. A heat dissipation container 54 is provided on the processing housing 1. One end of the heat dissipation container 54 is provided with a transmission pump 53. The output end of the transmission pump 53 communicates with the heat dissipation container 54. The input end of the transmission pump 53 communicates with one end of a transmission pipe 52 far from the corresponding conduction table 51. The other end of the other transmission pipe 52 far from the corresponding conduction table 51 communicates with the output end of the heat dissipation container 54. The heat dissipation container 54 is composed of a container body and a cooling device. The container body is filled with a heat exchange medium.

[0034] In specific implementation, the cooling device is used to reduce the temperature of the heat exchange medium. When the transmission pump 53 is operating, the heat exchange medium reciprocally circulates in the container body and the crushing wheel 2 in turn. At this time, the heat exchange medium will carry the heat on the crushing wheel 2 to the heat dissipation container 54 and be cooled by the cooling device. The cooling device can be a heat exchanger or other corresponding devices, which is common knowledge in this field. Therefore, the specific structural composition and working principle thereof will not be elaborated too much in this text.

[0035] In one embodiment, the dust reduction mechanism 6 includes atomizing nozzles 61 installed on the outer walls on both sides of the processing housing 1. The input end of each atomizing nozzle 61 is provided with a conveying pipeline 62 communicating therewith. One end of the conveying pipeline 62 far from each atomizing nozzle 61 communicates with one of the conduction tables 51. The heat exchange medium is a liquid. The circulating cooling mechanism 5 further includes an injection interface 55 installed on and communicating with the heat dissipation container 54.

[0036] In specific implementation, when the transfer pump 53 is working, part of the liquid in one of the conduction platforms 51 will flow into the conveying pipeline 62, and is sprayed downward outside the processing housing 1 through the atomizing nozzle 61, so as to perform dust suppression treatment on the phosphate slag that has been processed and is being transported outside the processing housing 1. Since part of the liquid will be ejected from the atomizing nozzle 61, the liquid in the heat dissipation container 54 will gradually decrease. At this time, new heat exchange medium can be supplemented into the heat dissipation container 54 through the injection interface 55.

[0037] In one embodiment, a liquid level sensor is installed in the heat dissipation container 54.

[0038] With such a design, the liquid level sensor is used to detect the liquid level in the heat dissipation container 54. When the detected liquid level reaches the threshold value, it sends a signal to the corresponding position (such as the terminal) to remind the staff to supplement.

[0039] In one embodiment, the power mechanism includes a transmission belt group 3 provided at one end of one of the crushing wheels 2. A motor 4 is installed on the processing housing 1. The transmission belt group 3 includes two transmission wheels and a transmission belt arranged on the two transmission wheels and in transmission cooperation with them. The two transmission wheels are coaxially installed on one of the crushing wheels 2 and the moving end of the motor 4 respectively. Gears 7 that mesh with each other are provided at the other ends of adjacent two crushing wheels 2 away from the transmission belt group 3.

[0040] In specific implementation, when the motor 4 works, it will drive the transmission belt group 3 to move, and one of the crushing wheels 2 connected to the transmission belt group 3 will rotate accordingly. Through the meshing of the gears 7, it will drive another adjacent crushing wheel 2 to rotate, so as to perform crushing treatment on the phosphate slag.

[0041] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative position relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, the directional indications will also change accordingly.

[0042] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second" can explicitly or implicitly include at least one such feature.

When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0043] In addition, "a plurality of" means more than two.
