The conventional pipeline distribution has the problems of unstable output, concentrated output, and difficulty in uniform distribution, especially in the feeding of equipment such as vibrating screens and jigs, which causes low equipment efficiency and affects the overall output of the mineral processing process.
[0003] Most of the existing slurry distribution is carried out by pumping and gravity pipes. Since the slurry outlet volume transported by pipelines is relatively concentrated, and some mineral processing equipment, uniform ore feeding and stable feed volume have a great impact on the operation stability of subsequent equipment and process flow. For example, the slurry fed into the vibrating screen through the pipeline is concentrated in the middle of the screen, and the surrounding screen cannot be fully utilized, resulting in low screening efficiency.

[0017] In the figure: 1-slurry conveying pipe, 2-funnel body, 3-screen, 4-chute, 5-slag receiving box, 6-high pressure flushing head, 7-gate, 8-connecting nut, 9-screw, 10-bearing and bearing seat, 11-handwheel, 12-arc outlet, 13-support frame. DETAILED DESCRIPTION
[0018] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0019] like Figure 1 As shown, a slurry funnel with uniform distribution includes a slurry conveying pipe 1, a funnel body 2 is arranged below the slurry conveying pipe 1, the top opening of the funnel body 2 is inclined, a screen 3 is arranged inside the funnel body 2, the screen 3 is inclined and has the same inclination direction as the top opening of the funnel body 2, the inclined lower end of the screen 3 is arranged at the inclined lower end of the funnel body 2, and a high-pressure water head 6 is arranged at the inclined upper end of the screen 3. A gate plate 7 is arranged at the lower part of the funnel body 2, a nut 8 is fixed at one end of the gate plate 7, a screw 9 is arranged inside the nut 8, and the screw 9 is connected to the hand wheel through a bearing 10, and the size of the gate plate 7 can be adjusted according to the amount of ore to control the amount of slurry. An arc outlet 12 is arranged at the bottom end of the funnel body 2, which has the advantage of reducing the kinetic energy and gravitational potential energy loss of the slurry flow, preventing the splashing of the slurry, and also ensuring the rapid feeding of ore to the lower equipment.
[0020] The upper layer of the funnel body 2 is provided with a screen 3. The screen 3 is detachable and inclined, and the pore size can be adjusted according to the pulp concentration and particle size. Its advantage is that the screen 3 can be replaced conveniently and quickly. At the same time, due to the inclined design, the sundries in the pulp can be far away from the ore feeding area under the impact of the pulp, without blocking the screen 3 and the funnel.
[0021] At the high end of the inclined screen 3, there is a high-pressure water head 6. Below the low end of the inclined funnel body 2, there is a chute 4, and below the chute 4, there is a slag receiving box 5. The high-pressure flushing water head 6 can be intermittently and regularly opened under the control of the solenoid valve. Its advantage is that it can regularly clean the sundries on the screen 3, prevent the sundries from accumulating on the screen 3 and blocking the screen holes, set slagging measures to prevent the sundries from being discharged outside and polluting the environment, and the slag receiving box 5 is used for storing the sundries on the screen.
[0022] The outlet of the pulp conveying pipe 1 and the funnel body 2 have a certain included angle, and the included angle is preferably about 30°, and the maximum cannot exceed 50°. Its advantage is that it can avoid the pulp directly impacting the funnel, causing splashing and affecting the surrounding environment, and at the same time reduce wear.
[0023] The inner wall of the funnel body 2 is lined with rubber. The rubber lining at the outlet where the funnel is connected to the gate is in a 'V'-shape. When the gate moves back and forth, the rubber lining closely adheres to the gate. Its advantage is that it can prevent the leakage of ore from the gap between the gate and the funnel, playing a good sealing role. On both sides of the inner wall of the funnel body 2 at the same height as the gate 7, there are 'C'-shaped gate support grooves. Its advantage is that it can provide a good supporting effect on the gate, restrain the displacement of the vertical plane of the gate, and prevent the gate from deforming under the impact of the pulp.
[0024] The bearing 10 is arranged in the bearing seat, the bearing seat is fixed on the support frame 13, and the support frame 13 is fixed on the funnel body 2. The bearing 10 and the bearing seat and the support frame 13 are for stabilizing the lead screw 9 and preventing its up and down movement from causing the lead screw to deform.
[0025] During use, the pulp passes through the pulp conveying pipe 1 and enters the funnel body 2. First, it passes through the screen 3 to filter out sundries. The sundries on the screen 3 are impacted by the regularly opened high-pressure flushing water head 6 and enter the chute 4, and then enter the slag receiving box 5 for storage. The pulp passing through the screen 3 then drives the gate 7 to move back and forth by rotating the handwheel 11, driven by the nut 8 and the lead screw 9, to adjust the ore discharge gap of the funnel body 2, so that the pulp is evenly discharged from the arc-shaped outlet 12 of the funnel.
[0026] The utility model has a simple structure and is easy to operate, realizes the uniform distribution of the pulp, solves the problem that most of the existing pulp distribution is carried out through pumping and self-flow pipelines for pulp feeding, the outlet quantity is concentrated and difficult to disperse, and it is difficult to achieve linear and uniform feeding, and improves the production operation efficiency of the downstream equipment.
