Abstract
Description
Technical Field
[0001] This utility model relates to the field of disc screen technology, and in particular to a disc screen. Background Technology
[0002] Disc screens are used in the screening of papermaking raw materials. During the screening process, some raw materials, such as reeds, tend to get tangled on the rotating shaft of the disc screen, and the tangling becomes more and more frequent and tighter, reducing the gap between the two discs. This causes the screened material to not fall smoothly, affecting the screening efficiency of the disc screen, and in severe cases, it can even cause the machine to stop. To solve this problem, a new disc screen is needed. Utility Model Content
[0003] The purpose of this invention is to provide a disc screen that is less prone to tangling.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0005] A disc screen includes a frame, on which rotating shafts are arranged parallel to each other at intervals. Discs are fixedly arranged coaxially at intervals on the rotating shafts. A drive mechanism for driving the rotating shafts to rotate is provided on the frame. A sleeve is provided on the rotating shaft next to the discs. The sleeve is rotatably connected to the rotating shaft. Connecting members are fixedly arranged between several sleeves on the same rotating shaft. The connecting members are fixedly connected to the frame.
[0006] As a further feature of this invention, the connector includes a support rod fixedly connected to each sleeve, and a number of support rods are fixedly connected to a fixing rod, which is fixedly connected to the frame.
[0007] As a further feature of this invention, both the support rod and the fixing rod are located directly below the sleeve.
[0008] As a further feature of this invention, an air blowing assembly is provided on the fixing rod.
[0009] As a further feature of this invention, the air blowing assembly includes an air pipe, which is fixedly connected to a fixing rod. An air pump is connected to the air pipe, and air holes are provided on the air pipe.
[0010] As a further feature of this utility model, the air tube and the fixing rod are an integral structure, the fixing rod is a hollow tube, and the fixing rod has an air hole.
[0011] As a further feature of this invention, the discs on adjacent rotating shafts are arranged in a uniformly staggered pattern.
[0012] As a further feature of this invention, the spacing between adjacent discs is equal.
[0013] As a further feature of this invention, the drive mechanism includes a sprocket fixedly connected coaxially to each rotating shaft, and a chain is provided between adjacent sprockets.
[0014] As a further feature of this invention, a motor is mounted on the frame, and the motor is connected to a sprocket drive.
[0015] The beneficial effects of this utility model are:
[0016] 1. When the disc screen is working, the rotating shaft drives the discs to rotate for screening. There is a sleeve between the discs. Without the sleeve, the rotating shaft will rotate the material and cause the material to get tangled on the rotating shaft. With the sleeve, the material has no rotational force because the sleeve is stationary, so it will not get tangled on the sleeve, thus avoiding the tangling of the material.
[0017] 2. By setting air holes on the fixed rod, air can be blown through the air holes during operation to prevent materials from falling onto the fixed rod, thereby preventing material accumulation. Attached Figure Description

[0022] The following will clearly and completely describe the technical solutions of the present invention in conjunction with specific embodiments. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0023] A disc sieve includes a frame 1, on which rotating shafts 2 are arranged parallel to each other, and discs 3 are fixedly arranged coaxially at intervals on the rotating shafts 2. A drive mechanism 4 is provided on the frame 1 to drive the rotating shafts 2 to rotate. A sleeve 5 is provided on the rotating shaft 2 next to the discs 3, and the sleeve 5 is rotatably connected to the rotating shaft 2. Connecting members 6 are fixedly arranged between several sleeves 5 on the same rotating shaft 2, and the connecting members 6 are fixedly connected to the frame 1.
[0024] Furthermore, the connector 6 includes a support rod 61 fixedly connected to each sleeve 5, and a plurality of support rods 61 are fixedly connected to a fixing rod 62, which is fixedly connected to the frame 1.
[0025] Furthermore, both the support rod 61 and the fixing rod 62 are located directly below the sleeve 5.
[0026] Furthermore, an air blowing assembly is provided on the fixing rod 62.
[0027] Furthermore, the air blowing assembly includes an air pipe, which is fixedly connected to the fixing rod 62. The air pipe is connected to an air pump, and an air hole 63 is provided on the air pipe.
[0028] Furthermore, the air tube and the fixing rod 62 are an integral structure, the fixing rod 62 is a hollow tube, and the fixing rod 62 is provided with an air hole 63.
[0029] Furthermore, the discs 3 on adjacent rotating shafts 2 are evenly and alternately arranged.
[0030] Furthermore, the spacing between adjacent discs 3 is equal.
[0031] Furthermore, the drive mechanism 4 includes a sprocket 41 that is coaxially and fixedly connected to each rotating shaft 2, and a chain 42 is provided between adjacent sprockets 41.
[0032] Furthermore, a motor 43 is provided on the frame 1, and the motor 43 is connected to a sprocket 41 for transmission.
[0033] The working principle of this embodiment is as follows:
[0034] When the disc screen is working, the rotating shaft 2 drives the disc 3 to rotate for screening. A sleeve 5 is set between the discs 3. Without the sleeve 5, the rotating shaft 2 will rotate and cause the material to rotate, thus wrapping the material around the rotating shaft 2. After the sleeve 5 is set, since the sleeve 5 is stationary, the material has no rotational force and will not wrap around the sleeve 5, thus avoiding the entanglement of the material.
[0035] By setting air holes 63 on the fixed rod, air can be blown through the air holes 63 during operation to prevent materials from falling onto the fixed rod, thereby preventing material accumulation.
