Description

Technical field:

[0001] The utility model relates to the field of tailings flotation technology, in particular to a flotation agent doser for improving the grade of concentrate. Background technology:

[0002] In the flotation process of lead-zinc ore, a dosing structure is often used to add a series of compounds such as flotation agents to the tailings, so as to effectively precipitate the substances in the tailings for further processing.

[0003] However, most existing dosing structures use electric pressure to press the medicine into the pipeline. After the medicine is added into the pipeline at one time, the dosing is uneven, which affects the mixing degree. In addition, the electric mechanism is prone to failure in a long-term vibrating working environment.

[0004] Therefore, a doser that can dosing medicine evenly and reduce the maintenance frequency of the electric mechanism is needed. Utility model content:

[0005] The purpose of the utility model is to provide a flotation reagent doser for improving the grade of concentrate.

[0006] The utility model is implemented by the following technical solutions:

[0007] A flotation reagent doser for improving the grade of concentrate comprises a dosing tube and a reagent box, the dosing tube and the reagent box are connected and communicated with each other through a hose, an adjusting cylinder is slidably connected in the dosing tube, a scale rod is fixedly installed on the inner bottom surface of the adjusting tube, a slidably connected L-shaped top rod is inserted into the adjusting tube, a sealing block is fixedly connected to the bottom end of the L-shaped top rod, a stopper is fixedly installed on the inner wall of the dosing tube, the stopper is ring-shaped, a screw rod is installed on the top end of the L-shaped top rod, a screw motor is provided at the bottom end of the screw rod, the output end of the screw motor is fixedly connected to the bottom end of the screw rod, a sensor is fixedly embedded in the bottom end of the adjusting tube, a slidably connected sleeve is sleeved on the scale rod, the side wall of the sleeve is fixedly connected to the side wall of the L-shaped top rod through a connecting rod, and a locking bolt is screwed on the side wall of the sleeve.

[0008] Preferably, a fixing seat is fixedly mounted on the side wall of the adjusting cylinder, the screw motor is fixedly mounted on the bottom end of the fixing seat, and the screw passes through the fixing seat and is slidably connected thereto.

[0009] The advantages of this utility model are as follows: starting the screw motor causes the screw to drive the L-shaped push rod to descend, thereby allowing the internal medicine to enter the pipeline, and then repeating the operation, so that the medicine is evenly divided into multiple equal parts and then added in sequence at intervals, so that the filling of the medicine is more uniform and the mixing degree is higher, and the device is simple and the cost is low. After the medicine is divided in advance, there is no need to consider the descent accuracy of the screw motor, as long as it can be lowered, thereby completing the dosing work, the operation is simple and convenient, and the cost is reduced. Description of the drawings:

[0010] Figure 1 It is a schematic diagram of the structure of the present utility model.

[0011] In the figure: dosing pipe 1, medicine box 2, adjustment cylinder 3, scale rod 4, sleeve 5, L-shaped push rod 6, screw rod 7, screw motor 8, sealing block 9, stop block 10. Specific implementation method:

[0012] like Figure 1 As shown, a flotation reagent doser for improving the grade of concentrate includes a dosing tube 1 and a reagent box 2. The dosing tube 1 is connected to the reagent box 2 and communicates with each other through a hose. An adjusting cylinder 3 is slidably connected in the dosing tube 1. A scale rod 4 is fixedly installed on the inner bottom surface of the adjusting cylinder 3. A slidably connected L-shaped top rod 6 is inserted into the adjusting cylinder 3. A sealing block 9 is fixedly connected to the bottom end of the L-shaped top rod 6. A stopper 10 is fixedly installed on the inner wall of the dosing tube 1. The stopper 10 is ring-shaped. A screw rod 7 is installed on the top of the L-shaped top rod 6. A screw motor 8 is provided at the bottom end of the screw rod 7. The output end of the screw motor 8 is fixedly connected to the bottom end of the screw rod 7. An inductor 11 is fixedly embedded in the bottom end of the adjusting tube 3. A slidably connected sleeve 5 is sleeved on the scale rod 4. The side wall of the sleeve 5 is fixedly connected to the side wall of the L-shaped top rod 6 through a connecting rod. A locking bolt is screwed on the side wall of the sleeve 5 When adding medicine, according to the current flow rate of the tailings, put a sufficient amount of medicine into the medicine box 2, then observe the scale on the scale rod 4, adjust it to the appropriate length, so that the medicine is evenly divided into multiple equal parts, and then enter the space between the adjusting cylinder 2 and the sealing block 9 in turn. When the sensor 11 senses, it means that one equal part has been filled between the two. Then start the screw motor 8, so that the screw drives the L-shaped top rod 6 to descend, so that the internal medicine enters the pipeline, and then repeat the operation. In this way, the medicine is evenly divided into multiple equal parts and then added in sequence at intervals, so that the filling of the medicine is more uniform and the mixing degree is higher. The device is simple and the cost is low. After the medicine is divided in advance, there is no need to consider the descent accuracy of the screw motor 8. As long as it can be lowered, the dosing work is completed. The operation is simple and convenient, and the cost is reduced.

[0013] A fixing seat is fixedly mounted on the side wall of the adjusting cylinder 3 , a lead screw motor 8 is fixedly mounted on the bottom end of the fixing seat, and a lead screw 7 passes through the fixing seat and is slidably connected thereto.

[0014] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
