Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of quicklime production equipment, specifically a safety feeding device for quicklime grinding equipment that prevents backflow. Background Technology
[0002] Limestone powder is an important raw material in many industries such as building materials, pharmaceuticals, chemicals, and metallurgy. Its production process includes raw material processing, calcination, cooling, finished product processing, and environmental protection measures. Raw material processing includes coarse crushing, fine crushing, and screening. Fine crushing requires equipment such as cone crushers and Raymond mills. Currently, the feeding method of crushing equipment is usually to use a conveyor belt to transport materials to an open feed hopper, and then they fall into the crushing equipment for crushing. During the fine crushing process, small pieces of limestone can easily splash out from the feed inlet, posing a certain safety hazard. Moreover, the site needs to be cleaned up after a period of time, which is time-consuming and labor-intensive. Furthermore, the degree of material discharge depends entirely on the speed of the conveyor belt and whether the material on the conveyor belt is evenly distributed. If the material on the conveyor belt is piled up, a sudden increase in material can easily cause the crushing equipment to stop. Therefore, further improvements are needed to meet the requirements. Utility Model Content
[0003] To address the above technical problems, this utility model provides a splash-proof safety feeding device for quicklime grinding equipment.
[0004] To solve the above-mentioned technical problems, the present invention provides a backsplash prevention safety feeding device for quicklime grinding equipment, comprising a feeding hopper, a support fixedly connected to one side of the feeding hopper and a baffle installed at an angle on the same side, several pillars fixedly connected at corresponding positions of the support and the baffle, and springs sleeved on the corresponding pillars, one end of the spring being fixedly connected to the support and the other end being fixedly connected to the baffle, a vibrating motor being fixedly connected to the back of the baffle, and a roller shaft rotatably connected to the bottom of the feeding hopper via a central shaft, with blades fixedly connected at intervals on the roller shaft, and one end of the central shaft passing through the feeding hopper and being driven by the motor.
[0005] Furthermore, a reinforcing rib is fixedly connected between the bottom of the support and the feed hopper.
[0006] This utility model has the following advantages compared with the prior art:
[0007] This invention features a rotating roller and blades below the feed hopper, which can control the rotation speed to achieve uniform feeding while preventing material particles from splashing out of the grinding device. By setting a vibrating baffle on one side of the feed hopper, vibration can be used to prevent material blockage when too much material accumulates in the feed hopper, thus avoiding manual unblocking and saving time and effort.

[0010] The present invention will be further described below with reference to the accompanying drawings.
[0011] like Figure 1 The quicklime grinding device shown includes a backsplash prevention safety feeding device, comprising a feed hopper 1, a support 3 fixedly connected to one side of the feed hopper 1, and a baffle 2 installed at an angle on the same side. The support 3 is L-shaped, and several sets of corresponding support columns 7 are fixedly connected to both the support 3 and the baffle 2. Springs 8 are sleeved on the corresponding support columns 7. One end of the spring 8 is fixedly connected to the support 3 and the other end is fixedly connected to the baffle 2. The wire diameter of the spring 8 is not less than φ10 and the outer diameter is not less than φ80 to ensure sufficient strength for support. A vibrating motor 9 is also fixedly connected to the back of the baffle 2. A roller shaft 5 is rotatably connected to the bottom of the feed hopper 1 through a central shaft 4. Blades 6 are fixedly connected at intervals on the roller shaft 5. One end of the central shaft 4 passes through the feed hopper 1 and is meshed with the output end of the motor for transmission.
[0012] To increase structural strength, a reinforcing rib 10 is fixedly connected between the bottom of the support 3 and the feed hopper 1.
[0013] The working process of this embodiment is as follows:
[0014] The bottom of the feed hopper 1 is connected to the feed end of the grinding device. When the conveyor belt pours limestone particles from above the feed hopper 1 into the feed hopper 1, the limestone particles will be evenly fed into the grinding device for crushing as the motor drives the roller shaft 5 and the blades 6 to rotate at a uniform speed. If the conveyor belt feeds a large amount of limestone particles that are piled up, resulting in a large amount of limestone particles in the feed hopper 1, the vibration motor 9 will be started to make the baffle 2 vibrate to ensure that the limestone particles below will not block the feed, thereby ensuring the feed of the grinding device.
