Description

Technical Field

[0001] This invention belongs to the technical field of ball mill auxiliary equipment, specifically referring to a ball mill discharge device. Background Technology

[0002] Ball mills are key equipment for further pulverizing materials after they have been crushed. They are widely used in industries such as cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal ore beneficiation, and glass and ceramics production. During the operation of a ball mill, the discharge device is a crucial component, and its performance directly affects the mill's discharge efficiency, finished product particle size accuracy, and equipment maintenance costs.

[0003] Currently, traditional ball mill discharge devices generally suffer from low discharge efficiency. Traditional discharge devices mostly adopt a single screen structure, which makes it easy for materials to accumulate at the discharge port. This is especially true for materials with high viscosity or fine particle size, which tend to adhere to the screen surface, causing screen hole blockage, thereby reducing the discharge speed and affecting the overall working efficiency of the ball mill. Furthermore, traditional discharge devices have poor material adaptability. They are not suitable for materials with different moisture content and viscosity, and are prone to problems such as poor discharge and unstable screening effect, making it difficult to meet diverse production needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the discharge efficiency of ball mill discharge devices in the prior art is low, and the traditional discharge devices are not adaptable to materials with different humidity and viscosity.

[0005] The technical solution adopted in this invention is as follows: The present invention discloses a ball mill discharge device, comprising a ball mill, a discharge pipe on the ball mill, a flow regulating valve on the discharge pipe, a feeder housing below the discharge pipe, a filter screen inside the feeder housing, and a multi-stage spray unit. The multi-stage spray unit includes a primary spray head connected to the discharge pipe, a solenoid valve connected to the primary spray head, and a secondary spray head penetrating the side wall of the feeder housing, the secondary spray head being connected to a solenoid valve through a pipe.

[0006] Furthermore, a U-shaped support is mounted on the upper part of the feeding machine housing, and a water storage tank is fixedly connected to the upper part of the U-shaped support. A pump is connected to the water storage tank, and the pump is connected to a diverter housing through a pipe. The diverter housing is connected to solenoid valve one and solenoid valve two respectively.

[0007] Furthermore, a humidity sensor is installed inside the discharge pipe, and a PLC controller is fixedly connected to the U-shaped support.

[0008] Furthermore, a back-blowing cleaning mechanism is fixedly connected to the side wall of the feeding machine housing, an air pump is connected to the back-blowing cleaning mechanism, branch pipes are connected to both sides of the back-blowing cleaning mechanism, and back-blowing heads that penetrate both sides of the feeding machine housing are connected to the branch pipes.

[0009] Furthermore, the bottom of the feeding machine housing is provided with a finished product collection box, and the side wall of the feeding machine housing is provided with a pull-out groove, on which an impurity filter screen frame is movably pulled out.

[0010] The beneficial effects achieved by the present invention using the above structure are as follows: 1. By setting up multi-stage spray units and switching and adjusting them through valves, two sprays are carried out in stages. First, pre-wetting is performed to break up the initial agglomerates and establish basic humidity. Then, the second spray is used for precise humidification and state control, reducing the problem of material discharge blockage. 2. The backflushing cleaning mechanism generates high-pressure airflow through an air pump and intermittently backflushes through branch pipelines to remove material adhering to the filter screen and prevent blockage.

[0013] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0014] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively. Example 1

[0015] like Figure 1-4 As shown, the present invention proposes a ball mill discharge device, including a ball mill 1, a discharge pipe 11 on the ball mill 1, a flow regulating valve 12 on the discharge pipe 11, a feeder housing 13 below the discharge pipe 11, a filter screen inside the feeder housing 13, and a multi-stage spray unit. The multi-stage spray unit includes a primary spray head 2 connected to the discharge pipe 11, a solenoid valve 21 connected to the primary spray head 2, a secondary spray head 22 penetrating the side wall of the feeder housing 13, and a solenoid valve 23 connected to the secondary spray head 22 through a pipe.

[0016] In practical use, the material is discharged from the discharge pipe 11 into the feeder housing 13 inside the ball mill 1. It first falls onto the filter screen for filtration. In order to avoid clogging caused by material adhesion, a primary spray head 2 can be used to spray the material in the discharge pipe 11 to increase humidity. After discharge, the material is sprayed a second time through the secondary spray head 22 for precise humidification and state control, reducing the problem of material clogging.

[0017] The upper part of the feeding machine housing 13 is equipped with a U-shaped support 3, and a water storage tank 31 is fixedly connected to the upper part of the U-shaped support 3. A pump 32 is connected to the water storage tank 31. The pump 32 is connected to a diverter housing 33 through a pipe. The diverter housing 33 is connected to a solenoid valve 21 and a solenoid valve 23 respectively. A humidity sensor is installed in the discharge pipe 11. A PLC controller 4 is fixedly connected to the U-shaped support 3.

[0018] During use, water is stored in the water tank 31 and pumped out by the pump 32 and distributed from the distributor housing 33. The spraying of the first-stage spray head 2 and the second-stage spray head 22 can be switched by controlling the opening of the solenoid valve 21 or the solenoid valve 23. The PLC controller 4 is used for automatic control based on the feedback from the humidity sensor. Example 2

[0019] like Figure 2 As shown, a back-blowing cleaning mechanism 5 is fixedly connected to the side wall of the feeding machine housing 13. An air pump 51 is connected to the back-blowing cleaning mechanism 5. Branch pipes 52 are connected to both sides of the back-blowing cleaning mechanism 5. Back-blowing heads 53 that penetrate both sides of the feeding machine housing 13 are connected to the branch pipes 52.

[0020] In the event of a blockage, the air pump 51 on the backflushing cleaning mechanism 5 generates a high-pressure airflow, which intermittently backflushes the surface of the filter screen through the branch pipe 52 and the backflushing head 53 to remove the attached material and prevent blockage.

[0021] The bottom of the feeding machine housing 13 is provided with a finished product collection box 6, and the side wall of the feeding machine housing 13 is provided with a pull-out groove 61. An impurity filter screen 62 is movably pulled out of the pull-out groove 61. After the material falls from the filter screen, the impurities are separated on the impurity filter screen 62, and the finished material falls into the finished product collection box 6. The impurity filter screen 62 can be easily disassembled and cleaned by pulling it out of the pull-out groove 61.

[0022] The above is the entire usage process of a ball mill discharge device.
