Description

Technical Field

[0001] The invention relates to a fine-grained material feeding device and a feeding method of the feeding device. Background Art

[0002] In the mineral processing of mines, low-grade tungsten concentrate or tin concentrate with a diameter of -2mm will be collected in a brick sedimentation tank. After concentration, it will be refined again to improve the grade of the concentrate. After precipitation in the sedimentation tank, the feed amount needs to be controlled by a switch to prepare a concentration of 10% to 25% for the next process. The traditional control method is to use a gate valve to control it. Because the ore particles are coarse, easy to clog and wear, the gate valve is not closed tightly, resulting in metal loss. The gate valve is also easily worn by coarse minerals. Frequent replacement of the gate valve affects production, causes cost increase, and is inconvenient to adjust the feed amount.

[0012] Furthermore, the length of the second groove is 100 mm, and the width of the second groove is 30 mm.

[0013] A feeding method for a feeding device, used in any of the above feeding devices, the method comprising:

[0014] The fourth tube body and the second tube body are separated from each other;

[0015] The feed amount is adjusted by rotating the third tube body and adjusting the connecting area between the second groove and the first groove, and the material entering the third tube body flows out to the outside through the lower end opening of the third tube body and the inner cavity of the second tube body in turn.

[0016] The present invention provides a fine-grained material feeding device and a feeding method for the feeding device, for example, a low-grade tungsten concentrate or tin concentrate is re-selected and purified as a feed material, wherein a first groove connecting the inner cavity of the first tube body and the outside is provided at the lower side of the first tube body, the first groove is used for feeding, the second tube body comprises a first part detachably connected to the lower end of the first tube body, and a second part connected to the first part, the central axis of the second part is perpendicular to the central axis of the first part, the third tube body is inserted into the first part through the inner cavity of the first tube body, the third tube body is provided with a second groove connecting the first groove and the inner cavity of the third tube body, the fourth tube body is connected through the inner cavity of the first tube body, and the second groove is provided on the third tube body.

[0017] The beneficial effect of the fine-grained material feeding device of the present invention is that the feed port is higher than the discharge port. If the position of the iron pipe slot is higher, the greater the height difference with the outlet, the greater the potential energy. After the material enters from the slot, it falls from a high place into the bottom of the 90° PVC elbow. The upper part of the slotted PVC pipe is hollow and communicates with the atmosphere. Under the dual effects of gravity and atmospheric pressure, the flow of the material becomes faster and faster, the outlet speed is greater than the inlet speed, and the flow of the material is smoother. If the incoming material particle size is coarse or the feed concentration requirement is high, the feed port can be opened higher to increase its potential energy and increase its flow rate, so that the pipeline will not be blocked. The sand and gravel in the material will wear the control switch. A long-handled plug wrapped with rags can be used to plug the pipeline tightly to solve the problem of loose closure due to wear.
