Description

Technical Field

[0001] The utility model relates to the technical field of iron ore processing, in particular to an ore flushing and spraying component. Background Art

[0002] The magnetic separator mainly uses the magnetism of the magnetic roller to absorb the iron ore powder, thereby separating the iron ore from other ore powders. The magnetic roller on the magnetic separator also needs to be unloaded. The traditional unloading method is to set a nozzle on a pipe parallel to the magnetic roller, flush the magnetic roller through the nozzle, and wash away the iron powder on the surface of the magnetic roller to achieve unloading. This unloading method has poor uniformity and often causes incomplete unloading. Therefore, the existing unloading method is mainly to unload the ore through waterfall unloading.

[0003] For example, patent application number CN201320003356.1 discloses a waterfall unloading device for a magnetic separator. The waterfall unloading device for a magnetic separator in this patent is installed vertically above the unloading area of ​​the magnetic separator. The horizontal water tank is equal in length to the magnetic roller of the magnetic separator. Water passes through the overflow weir plate to form a water curtain and flows to the surface of the magnetic roller to wash away the iron powder on the surface of the magnetic roller. The unloading is complete, fast and efficient.

[0004] This patent mainly utilizes the overflow weir plate to enable the water flow to fall on the magnetic roller in a waterfall-like manner. However, in actual use, due to the limited number of water inlet pipes on the sink and their insufficient distribution for absorption, the flow rates of water at different positions in the sink are different. The flow rate of water at the water inlet pipe is obviously greater than that at the adjacent position, which causes the water flow in the slow flow area to be carried away by the water flow in the fast flow area. Therefore, there is still a problem of uneven distribution of water on the overflow weir plate. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an ore flushing spray assembly to solve the problem of incomplete ore unloading in the waterfall type ore unloading device in the prior art described in the background technology.

[0006] In order to solve the above problems, the utility model provides the following technical solutions: a mineral flushing spray assembly, comprising

[0007] The pool has an overflow port on the side wall where the upper port is located;

[0008] The overflow weir plate is fixedly connected to the side wall of the pool at a position corresponding to the overflow outlet in an inclined manner, the upper end of the overflow weir plate is flush with the lower end wall of the overflow outlet, and a plurality of water flow grooves are evenly arranged on the inclined upper surface of the overflow weir plate;

[0009] The partition and baffle are fixedly connected in the water pool and separate the water pool into an inlet pool, a transition pool and an overflow pool, and the baffle is provided with a water hole;

[0010] The horizontal position of the upper surface of the baffle is higher than the horizontal position of the upper surface of the partition and higher than the horizontal position of the bottom of the overflow port;

[0011] The water collecting pipe is fixedly connected to a position on the pool corresponding to the water inlet pool. The water collecting pipe is provided with a plurality of water inlet pipes extending into the water inlet pool, and the water collecting pipe is also provided with a water supply pipe.

[0012] Preferably, an inclined guide plate is fixedly connected to the bottom of the overflow weir plate, for receiving water flowing out along the overflow weir plate.

[0013] Preferably, the water through hole on the baffle is lower in level than the upper surface of the partition and lower in level than the bottom of the overflow port.

[0014] Preferably: a sealing plate is fixedly connected to the partition, the water inlet pipe slides through the sealing plate, and the sealing plate is arranged horizontally.

[0015] The beneficial effects of adopting the above technical solution are:

[0016] The water inlet pool set up in the present application can receive the extremely fast water flow flowing in from the water inlet pipe, and the sealing plate can prevent the water flow from flowing into the transition pool with great power, and the function of the water hole is to introduce the water in the transition pool into the overflow pool. The main purpose of the whole process is to make the water flow fluctuate less and avoid unevenness when flowing out of the overflow port, and the purpose of the water flow trough is to prevent the high-speed water flow from carrying away the low-speed water flow. The gaps between adjacent water flow troughs are reasonable and will not cause uneven unloading of ore. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-2 In the first embodiment, a mineral flushing spray assembly includes:

[0022] The water pool 10 has an overflow port 11 on the side wall where the upper port is located;

[0023] The overflow weir plate 70 is fixedly connected to the side wall of the pool 10 at a position corresponding to the overflow port 11 in an inclined manner. The upper end of the overflow weir plate 70 is flush with the lower end wall of the overflow port 11. The inclined upper surface of the overflow weir plate 70 is evenly provided with a plurality of water flow grooves 71.

[0024] The partition plate 20 and the baffle plate 40 are fixedly connected in the water pool 10, and separate the water pool 10 into an inlet pool 21, a transition pool 50 and an overflow pool 60. The baffle plate 40 has a water hole 41;

[0025] The horizontal position of the upper surface of the baffle 40 is higher than the horizontal position of the upper surface of the partition 20 and higher than the horizontal position of the bottom of the overflow port 11;

[0026] The water collecting pipe 31 is fixedly connected to a position on the water pool 10 corresponding to the water inlet pool 21 . The water collecting pipe 31 has a plurality of water inlet pipes 30 extending into the water inlet pool 21 . The water collecting pipe 31 also has a water supply pipe 32 .

[0027] This embodiment is implemented as follows:

[0028] When the present application is in use, water is sent to the water collecting pipe 31 through the water supply pipe 32, and is sent to the water inlet pool 21 through the water inlet pipe 30, and then the water flows over the partition 20, enters the transition pool 50, and then enters the overflow pool 60 through the water hole 41 on the baffle 40, and then flows out through the overflow port 11. The function of the partition 20 and the baffle 40 in the present application is to slow down the water flow so that the water flow can smoothly and evenly pass through the overflow port 11, and then the water flows to the overflow weir plate 70. The water flow trough 71 on the overflow weir plate 70 can prevent the fast-flowing part of the water flow from being carried away by the low-flowing part of the water flow, which can effectively make the water flow evenly fall on the magnetic roller, thereby improving the uniformity of water flow unloading.

[0029] In the present application, the distance between the water troughs 71 is reasonable, and the distance between adjacent water troughs 71 is 0.5 cm-0.8 cm, so that the distance between the water troughs 71 will not cause uneven unloading of ore.

[0030] The water collecting pipe 31 of the present application is installed on the cross beam plate 33 on the pool 10 .

[0031] The advantage of the present application over the prior art is that the water flow can be evenly distributed on the overflow weir plate 70 .

[0032] See also Figure 2 , an inclined guide plate 72 is fixedly connected to the bottom of the overflow weir plate 70;

[0033] The guide plate 72 is used to guide the water flowing out along the overflow weir plate 70 to flow toward the magnetic roller again.

[0034] See also Figure 2 , the level of the water hole 41 on the baffle 40 is lower than the level of the upper surface of the partition 20 and lower than the level of the bottom of the overflow port 11;

[0035] By arranging the water through hole 41 at a level lower than the overflow port 11 and the upper surface of the partition 20 , the water in the transition pool 50 can flow smoothly from the bottom into the overflow pool 60 .

[0036] See also Figure 2 A sealing plate 22 is fixedly connected to the partition plate 20, and the water inlet pipe 30 slides through the sealing plate 22, and the sealing plate 22 is horizontally arranged;

[0037] The sealing plate 22 can block and slow down the water rushing down from the water inlet pipe 30, so that the water flow from the water inlet pool 21 to the transition pool 50 is more stable.

[0038] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
