Description

Technical Field

[0001] The utility model relates to the technical field of crushing and transporting pyrometallurgical lead-zinc sintering materials, in particular to a device for preventing material accumulation of a roller body and a material discharge chute of a smooth roller crusher. Background Art

[0002] In the ISP lead-zinc smelting process, the returned powder undergoes four crushing steps before being returned to the process for re-feeding. Before entering the fourth crushing step (i.e., the smooth roller crusher), the returned powder enters a cooling drum where it is cooled by the slurry and water produced by wet dust removal to meet the moisture and temperature requirements of the subsequent process. However, this water-cooled returned powder easily adheres to the crushing rollers and the discharge chute, causing roller sticking and chute clogging, leading to equipment downtime and disrupting normal production. Furthermore, cleaning up the accumulated material is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this utility model is to provide a device for preventing material accumulation on the roller and the material chute of a smooth roller crusher, which can effectively solve the problem of material sticking and accumulating between the roller and the chute, and improve the stability and continuity of the production process, so as to solve the problems raised in the above background technology.

[0019] Example 1

[0020] like Figure 1-2 , this embodiment provides a device for preventing material accumulation in the roller body and discharge chute of a smooth roller crusher, including a flushing pipeline part and a control part, the flushing pipeline including two groups of flushing branch pipes 1, the two groups of flushing branch pipes 1 are connected to the water supply main 3 through an electric water supply valve 2, the outlet of one group of flushing water pipes is located at the upper side of the crushing roller 12 roller body for flushing the crushing roller 12 roller body, and the outlet of the other group of flushing water pipes is located in the discharge chute 13 for flushing the discharge chute 13; the control part includes a photoelectric sensor 4 and a rotating rod 5 of a "U"-shaped structure, the photoelectric sensor 4 is installed on one side of the conveyor belt 11, the photoelectric sensor 4 is electrically connected to the normally open electric water supply valve 2, a sleeve 6 is rotatably sleeved on the middle section of the rotating rod 5, the sleeve 6 is fixed on the support rod, and rectangular baffles 7 are provided at both ends of the rotating rod 5, the rectangular baffle 7 at one end is located directly above the conveyor belt 11, and the rectangular baffle 7 at the other end is located directly in front of the photoelectric sensor 4. The specific installation positions of the photoelectric sensor 4 and the rotating rod 5 ensure that when the conveyor belt 11 is normally conveying material, the rectangular baffle 7 directly above the conveyor belt 11 is pushed up, and the rectangular baffle 7 directly in front of the photoelectric sensor 4 is also pushed up. The pushed-up position exceeds the sensing range of the photoelectric sensor, and the sensor stops working. When there is no material being conveyed on the conveyor belt 11, the rectangular baffle 7 directly above the conveyor belt 11 falls, and the rectangular baffle 7 directly in front of the photoelectric sensor 4 falls together. The falling position is within the sensing range of the photoelectric sensor 4, and the photoelectric sensor 4 starts working. At the same time, the installation position of the water outlet of the flushing branch pipe 1 is determined based on the position of the accumulated material between the roller body of the crushing roller 12 and the discharge chute 13. The flushing branch pipe 1 and the electric water supply valve 2 are installed, and the photoelectric sensor 4 is connected to control the electric water supply valve 2, thereby completing the installation of the entire device.

[0021] The flushing branch pipes 1 are stainless steel water pipes, and a group of flushing branch pipes 1 includes two symmetrically arranged stainless steel water pipes.

[0022] The flushing branch pipes 1 are stainless steel water pipes, and a group of flushing branch pipes 1 includes two symmetrically arranged stainless steel water pipes.

[0023] The rotating rod 5 is installed at a distance of 0.5 m from the tail of the transport belt.

[0024] The normally open electric water supply valve 2 is a Q911W-10TDN25 power-off reset normally open electric water supply valve.

[0025] The support rods include support rod a8 and support rod b9. The upper end of support rod a8 is fixed on the left side of sleeve 6, and the lower end is fixed on the conveyor belt bracket; the upper end of support rod b9 is fixed on the right side of sleeve 6, and the lower end is fixed on the ground.

[0026] The photoelectric sensor 4 is installed on the upper end of the support rod c10, and the support rod c10 is fixed on the ground.

[0027] The operating principle of the present invention is that when the feeding belt is transporting materials normally, the rectangular baffle 7 directly above the conveying belt is pushed up to point B by the thrust of the belt transporting materials, and the rectangular baffle 7 directly in front of the photoelectric sensor 4 is pushed up by the connecting rod, away from the photoelectric sensor 4, the photoelectric sensor 4 stops working, the circuit is in a disconnected state, the electric water supply valve 2 is opened, and the water flows through the power-off reset normally open water supply valve and is divided into two paths through the pipeline, one path for flushing the crushing roller body, and the other path for flushing the discharge chute. The material flows down smoothly under the flushing action of the water flow, does not stick to the crushing roller, and is also unobstructed when passing through the discharge chute, avoiding the occurrence of sticking and accumulation of materials, and at the same time plays the role of secondary water cooling and powder return. When there is no material being transported on the belt, the rectangular baffle 7 directly above the conveyor belt falls to point A only under the action of gravity, and the rectangular baffle 7 directly in front of the photoelectric sensor 4 falls together and approaches the photoelectric sensor. The photoelectric sensor starts to work, the circuit is in a closed state, the valve is closed, and the water flow stops automatically, thereby achieving the purpose of automatic water addition and avoiding the equipment being "flooded" due to the valve not closing in time when the material is cut off.
