Description

Technical Field

[0001] The utility model relates to the technical field of rolling screen drum cleaning, in particular to a rolling screen cleaning device. Background Art

[0002] In the fertilizer production process, most of the screening and transportation of granular materials are completed by rolling screens. Since the processing is carried out in a high temperature and humid environment, the temperature and humidity of the particles themselves are relatively high; therefore, the particles will stick to the rolling screen, and the powder on the particles will fall off and block the screen. The screening cannot be carried out normally due to the blockage of the screen, resulting in unqualified products.

[0003] The current screen cleaning methods are mostly regular manual cleaning and mechanical knocking cleaning; the above cleaning methods have the following problems:

[0004] 1. Manual external knocking and cleaning, which is very damaging to the screen cylinder and can easily cause the screen to break and deform;

[0005] 2. Manual internal cleaning: This method requires manual entry into the screen drum after the machine is shut down to clean the inside. This method is suitable for large screen drums but not for small screen drums.

[0006] 3. Mechanical knocking cleaning can easily cause damage to the screen due to the unreasonable knocking structure. Utility Model Content

[0021] In the description of the embodiments of the present utility model, it should be noted that if the terms "upper", "lower", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the utility model product is usually placed when in use. It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, if the terms "first", "second", etc. appear in the description of the present utility model, they are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0022] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0023] As shown in the accompanying drawings, the utility model includes a support frame 2 located above the screen drum 1 of the rolling screen, the support frame 2 is provided with a transmission shaft 3 and a driving assembly 4 for driving the transmission shaft 3 to rotate, and the transmission shaft 3 is provided with a plurality of belts 5 for whipping the outer wall of the screen drum 1 along its axial direction.

[0024] The driving component 4 is a motor reducer component. The rotation speed of the driving component 4 is lower than the rotation speed of the screen drum 1, that is, the rotation speed of the driving component 4 is not synchronized with the rotation speed of the screen drum 1. Each time the belt 5 falls and hits the screen drum 1, the position is also different, which is convenient for shaking off the material adhering to the screen drum 1.

[0025] A plurality of sets of fixing clamps 6 are arranged on the transmission shaft 3 along its axial direction. One end of the belt 5 is mounted on the fixing clamp 6. Each set of fixing clamps 6 consists of two and are symmetrically mounted on the transmission shaft 3. Two adjacent sets of fixing clamps 6 are cross-staggered.

[0026] There are no less than four groups of fixed clamps 6 in this case, and each group of fixed clamps 6 is equidistantly distributed, that is, no less than two belts 5 are whipped onto the screen drum 1 each time, so that various parts of the screen drum 1 can be evenly and intermittently whipped, and the driving component 4 controls the rotation speed of the transmission shaft 3 to three revolutions per minute.

[0027] The fixing clamp 6 is welded on the transmission shaft 3 , and one end of the belt 5 is fixed on the fixing clamp 6 through a set of screws.

[0028] A reinforcement belt layer 7 is provided on the fixing clamp 6 located at the rear side of the belt 5 in the moving direction. The length of the reinforcement belt layer 7 is not more than one third of the length of the belt 5 .

[0029] The reinforced belt layer 7 acts as a reinforcing plate, providing certain support to the rear side of the belt 5. When the belt 5 follows the rotation, the rear side close to the fixed clamp 6 is supported by the reinforced belt layer 7, which can reduce the bending degree of the fixed end of the belt 5, making the bending of the fixed end of the belt 5 gentler, making the belt 5 more stable when being thrown out and whipped, and also preventing the fixed end of the belt 5 from loosening or even breaking due to excessive bending.

[0030] A weighted belt layer 8 is provided on the belt 5 at one end away from the fixed clamp 6 , and the weighted belt layer 8 is located at the rear side of the belt 5 in the moving direction.

[0031] The weighted belt layer 8 is used to increase the weight of the movable end of the belt 5 and to increase the force of whipping the screen drum 1 .

[0032] The width of the belt 5 is 100 mm, and the thickness of the belt 5 is 12 mm. The reinforced belt layer 7 and the counterweight belt layer 8 are the same as the width and thickness of the belt 5 .

[0033] In this case, the belt 5, the reinforced belt layer 7 and the counterweight belt layer 8 are made of the same material, all of which are made of rubber and fiber composite materials. The length and height of the belt 5 are controlled so that the belt 5 can hit the side of the screen drum 1 near the top every time it falls. In this case, the length of the belt 5 is 1500mm, and the gap between the drive shaft 3 and the screen drum 1 is 900mm.
