Description

Technical Field

[0001] This invention belongs to the field of roller sleeve technology and relates to an energy-saving coal mill roller sleeve device based on hydraulic adjustment. Background Technology

[0002] Rollers are components in devices such as roller presses and vertical mills. These devices are commonly used in crushing and grinding operations in industries such as mining, cement, and metallurgy. For ease of processing and maintenance, rollers are generally composed of a roller sleeve and a mandrel. The roller sleeve is fitted over the mandrel to provide protection.

[0003] Publication No. CN209317785U discloses a roller sleeve for a coal mill in a thermal power plant, comprising a grinding roller, a roller support, a slide bar, a U-shaped rod, a support rod, a gear, a rotating rod, a push rod, a locking tooth, a locking rod, a limiting spring, a threaded rod, a threaded sleeve, and a connecting rod. The grinding roller is symmetrically arranged below the roller support. Support rods are symmetrically fixedly connected to both sides of the bottom of the roller support. Rotating rods are symmetrically arranged below the roller support, with both ends of each rotating rod rotatably connected to a corresponding support rod via bearings. U-shaped rods are symmetrically arranged below the roller support, with both ends of each rotating rod passing through a corresponding support rod and fixedly connected to the corresponding ends of the U-shaped rod. Connecting rods are provided inside each U-shaped rod, with both ends of each connecting rod fixedly connected to both sides of a corresponding U-shaped rod. A threaded sleeve is fixedly connected to the side of the grinding roller closest to the U-shaped rod, and a threaded rod is threadedly connected inside each threaded sleeve via threaded engagement. Both ends of the threaded rod pass through the corresponding threaded sleeve and are connected to the corresponding U-shaped rod and connecting rod via bearings. The roller support is symmetrically equipped with insertion slots on its top. Each insertion slot contains a sliding rod, the top of which passes through the corresponding insertion slot and is exposed to the air. Each insertion slot has a fixed push rod at its bottom, the end of which, away from the insertion slot, passes through the roller support and is fixedly connected to a locking tooth. Gears are fitted and fixed to the outside of each rotating rod, meshing with corresponding locking teeth. Each roller support has a circular groove on one side of the insertion slot, containing a locking rod. Each sliding rod has a locking hole on the side near the circular groove, the end of which passes through the circular groove and engages with the corresponding locking hole. The roller support has symmetrically equipped slide tracks on its top, all connected to the corresponding circular grooves. Each locking rod has a fixedly connected slide bar on its outside, slidingly connected to the corresponding slide track. Each circular groove contains a limit spring, both ends of which are fixedly connected to the corresponding locking rod and the inner wall of one side of the circular groove. After adjustment, press the slide rod to engage the locking rod with the locking hole, which allows the locking teeth to mesh with the gear, preventing the rotating rod from rotating and thus fixing the angle of the grinding roller. This facilitates adjustment and maintenance of the grinding roller, as well as adjusting the angle between the grinding roller and the grinding disc, thus controlling the size of the grinding particles. Next, rotating the knob rotates the threaded rod, allowing adjustment of the position of the threaded sleeve, thereby adjusting the height between the grinding roller and the grinding disc. When the coal lumps in the coal mill need to be adjusted to change the size of the grinding particles, pulling the push block separates the locking rod from the locking hole. The slide rod then slides upwards under the force of the extension spring, causing the locking teeth at the bottom of the push rod to separate from the gear. Rotating the turntable then allows adjustment of the grinding roller angle via the rotating rod. After adjustment, pressing the slide rod to engage the locking rod with the locking hole again allows the locking teeth to mesh with the gear, preventing the rotating rod from rotating and thus fixing the angle of the grinding roller. This facilitates adjustment and maintenance of the grinding roller, as well as adjusting the angle between the grinding roller and the grinding disc, thus controlling the size of the grinding particles.

[0004] However, when many roller sleeves are in operation, if the position of the roller sleeve needs to be adjusted, the equipment must be shut down to stop the roller sleeve from working before the adjustment can be carried out, which greatly reduces the processing efficiency, and restarting the equipment requires more energy.

[0005] In view of this, the present invention proposes an energy-saving coal mill roller sleeve device based on hydraulic regulation. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an energy-saving coal mill roller sleeve device based on hydraulic adjustment. This solves the problem that in many existing roller sleeves, when the position of the roller sleeve needs to be adjusted, the equipment must be shut down to stop the roller sleeve from working before the adjustment can be carried out, which greatly reduces the processing efficiency and requires more energy to restart the equipment.

[0007] To achieve the above objectives, this invention discloses an energy-saving coal mill roller sleeve device based on hydraulic adjustment, comprising a base, a slide rail fixedly connected to the top of the base, a connecting plate fixedly connected to the surface of the slide rail, a rotating shaft rotatably connected inside the connecting plate, a motor fixedly connected to the connecting plate, a first gear set fixedly connected to the surface of the rotating shaft, a first roller tire rotatably connected to the base fixedly connected to the side of the first gear set, a first roller sleeve disposed on the surface of the first roller tire, an mounting plate fixedly connected to the surface of the slide rail, a connecting ring rotatably connected inside the mounting plate, a connecting sleeve rotatably connected to the mounting plate and slidably connected to the rotating shaft fixedly connected to the inner wall of the connecting ring, a second gear set fixedly connected to the rotating shaft connected to the side of the connecting sleeve, a second roller tire fixedly connected to the side of the second gear set, a second roller sleeve disposed on the surface of the second roller tire, a sliding plate rotatably connected to the second roller tire slidably connected to the surface of the slide rail, and an electro-hydraulic rod connected to the sliding plate fixedly connected to the base.

[0008] A further improvement of the energy-saving coal mill roller sleeve device based on hydraulic regulation described in this invention is as follows:

[0009] Furthermore, a baffle is inserted inside the slide rail, and a locking block that penetrates the slide rail is inserted inside the baffle. The locking block is internally threaded with a screw embedded inside the slide rail.

[0010] Furthermore, the slide rail is arranged in a horizontal straight line, and the slide plate forms a horizontal sliding structure through an electro-hydraulic rod.

[0011] Furthermore, both the first gear set and the second gear set consist of two sets of perpendicular bevel gears, and the first gear set and the second gear set rotate synchronously.

[0012] Furthermore, the mounting plate has a slot inside that matches the size of the connecting ring, and the connecting sleeve rotates inside the mounting plate via a rotating shaft.

[0013] Furthermore, the second roller sleeve slides horizontally along the slide rail under the action of the electro-hydraulic rod.

[0014] Furthermore, two sets of baffles are symmetrically arranged.

[0015] Furthermore, the two sets of baffles shield the sides of the first and second roller sleeves.

[0016] Furthermore, the base is provided with a drop opening located at the gap between the first roller sleeve and the second roller sleeve.

[0017] Furthermore, the locking block and the baffle are in a mutually perpendicular locking state.

[0018] The present invention has the following beneficial effects:

[0019] In specific operation, the energy-saving coal mill roller sleeve device based on hydraulic adjustment described in this invention utilizes an electric push rod. When it is necessary to adjust the distance between the first and second roller sleeves, the electric hydraulic rod can be opened, causing it to pull the sliding plate to the right. The sliding plate then slides to the right along the slide rail, and the mounting plate also slides to the right. The connecting sleeve slides along the rotating shaft through the connecting ring. When the sliding plate and the mounting plate move synchronously, they drive the second gear set and the second roller sleeve to move, thus achieving the purpose of adjusting the second roller sleeve through the electric hydraulic rod. This solves the problem that in many existing roller sleeves, when the position of the roller sleeve needs to be adjusted, the equipment must be shut down to stop the roller sleeve from working before the adjustment can be carried out, which greatly reduces processing efficiency and requires more energy to restart the equipment.

[0020] Furthermore, in this invention, by setting a baffle, the baffle can be inserted into the corresponding slot of the slide rail, and then the block is inserted through the slide rail into the baffle. At this time, the baffle and the block will engage with each other. Finally, the baffle is fixed with screws. After the baffle is installed, the baffle can play a blocking role, preventing the first roller sleeve and the second roller sleeve from splashing fragments everywhere when processing coal.

[0021] Furthermore, the first roller sleeve is directly driven by a motor-shaft-first gear set to achieve basic grinding function; the second roller sleeve is slidably connected to the shaft through a connecting sleeve, and its axial displacement is adjusted by an electro-hydraulic rod pushing a sliding plate, forming a modular structure of "fixed roller + adjustable roller". This reduces the length of the mechanical transmission chain and lowers the failure rate (such as the risk of gear wear and transmission shaft breakage); the hydraulic adjustment and mechanical drive are decoupled, avoiding impact on the drive system during adjustment.

[0045] Example 3

[0046] Based on Embodiment 1, a preferred embodiment of the energy-saving coal mill roller sleeve device based on hydraulic regulation provided by the present invention is as follows: Figures 1 to 5 As shown: A baffle 17 is inserted inside the slide rail 2, and a locking block 18 that penetrates the slide rail 2 is inserted inside the baffle 17. A screw 19 that is embedded inside the slide rail 2 is threaded inside the locking block 18.

Finally, the baffle 17 is fixed by the screw 19.

[0049] The working principle and usage process of this invention are as follows: First, when the equipment needs to be controlled to work, the motor 5 is turned on to control the rotating shaft 4 to rotate. At this time, the first gear set 6 and the second gear set 8 will rotate, and respectively drive the first roller sleeve 7 and the second roller sleeve 10 to rotate, and the equipment starts to work. When it is necessary to adjust the distance between the first roller sleeve 7 and the second roller sleeve 10, the electric hydraulic rod 13 can be turned on to pull the slide plate 12 to the right. The slide plate 12 then slides to the right along the slide rail 2.

When the slide plate 12 and the mounting plate 14 move synchronously, they will drive the second gear set 8 and the second roller sleeve 10 to move, so as to achieve the purpose of adjusting the second roller sleeve 10 through the electric hydraulic rod 13.

[0050] By setting baffle 17, baffle 17 can be inserted into the corresponding slot of slide rail 2. Then, the locking block 18 passes through slide rail 2 and is inserted into the baffle 17. At this time, baffle 17 and locking block 18 will engage with each other. Finally, baffle 17 is fixed by screw 19. After baffle 17 is installed, baffle 17 can play a blocking role to prevent the first roller sleeve 7 and the second roller sleeve 10 from splashing fragments everywhere when processing coal.
