Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal dryers, in particular to a centrifugal dryer with an automatic cleaning function. Background Art

[0002] Centrifugal rotary dryers are also commonly known as centrifugal dryers. Centrifugal dryers usually consist of a rotating cylinder or disc with one or more layers of screens or filters inside. The wet material is placed in the rotating cylinder or disc. When the equipment is started, the cylinder or disc begins to rotate at high speed. Due to the centrifugal force generated by the rotation, the moisture is forced to leave the material and pass through the screen or filter, and then discharged to the outside of the equipment, while the dried material remains on the screen or filter. The filter can be in a cylindrical state, set inside the dryer, in a non-rotating state, and the material is stirred by the rotating component to rotate in the filter cylinder to complete the drying.

[0003] However, during the use of existing centrifugal drying equipment, some materials are likely to adhere to the inner wall of the filter cylinder, causing blockage and reducing its filtering effect. In addition, there is also a risk of blockage during the discharge process, affecting subsequent use. In view of this, we propose a centrifugal dryer with automatic cleaning function.

DETAILED DESCRIPTION

[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Example

[0021] like Figure 1-4 As shown, the utility model proposes a centrifugal dryer with automatic cleaning function, including a heating tank 1, a support seat 2 and a filter cartridge 3. The heating tank 1 is fixedly mounted on the support seat 2, and the heating tank 1 is supported by the support seat 2; the filter cartridge 3 is mounted on the inner wall of the heating tank 1, and is used to cooperate with the heating tank 1 to dry the material. The heating tank 1 is equipped with a stirring assembly 4 for stirring the material. The stirring assembly 4 includes a motor 41, which is mounted on the inner wall of the bottom of the heating tank 1. The bottom end of the first rotating shaft 42 is connected to the output end of the motor 41, so that the first rotating shaft 42 is driven to rotate by the motor 41; the first pulley 43 is fixedly sleeved on the outer ring surface of the first rotating shaft 42, and the belt 45 is sleeved in the transmission groove of the first pulley 43 for subsequent transmission; a plurality of stirring blades 44 are welded on the outer ring surface of the motor 41, and are arranged inside the filter cartridge 3, so as to facilitate the stirring of the material inside the filter cartridge 3, and to accelerate the drying speed of the material.

[0022] Furthermore, a first positioning assembly 5 is provided in the filter cartridge 3 for facilitating the limiting of the cleaning brush 13. The first positioning assembly 5 includes a dial plate 51. A vertical rod 52 is fixedly mounted on a groove wall formed on the side wall of the dial plate 51. A first positioning groove is formed at the bottom of the cleaning brush 13. A positioning shaft 53 is welded to the top wall of the vertical rod 52 and is arranged in the first positioning groove, which serves as a preliminary limiting state for the cleaning brush 13 in a vertical state. The cleaning surface of the cleaning brush 13 is in close contact with the inside of the filter cartridge 3, which facilitates its cleaning and avoids material adhering to the wall of the filter cartridge 3, causing it to be blocked and affecting the subsequent drying of the material.

[0023] Furthermore, a second positioning assembly 6 is provided in the filter cartridge 3 to facilitate position limitation of the first positioning assembly 5. The second positioning assembly 6 includes a movable block 61. One side wall of the movable block 61 is fixedly connected to one end of a spring 62. The other side of the movable block 61 is fixedly connected to one side wall of the positioning block 63. The toggle shaft 64 is welded to the top wall of the movable block 61. A movable groove is provided on the stirring blade 44 at the top. The movable block 61 is arranged in the movable groove. A limited sliding groove is provided on the top wall of the movable groove. The top end of the toggle shaft 64 passes through the limited sliding groove. The other end is fixedly connected to a side wall of the movable groove, and a second positioning groove is opened on the back wall of the cleaning brush 13, and the positioning block 63 is arranged in the second positioning groove to fix the position of the cleaning brush 13 so that the cleaning surface of the cleaning brush 13 is in close contact with the inner wall of the filter cartridge 3. When the toggle shaft 64 is pulled to drive the movable block 61 to squeeze the spring 62, the positioning block 63 can be driven to move to the second positioning groove, thereby releasing the restriction on the position of the cleaning brush 13, making it convenient for the staff to take out the cleaning brush 13 from the heating tank 1 for replacement or cleaning, to avoid its aging affecting the cleaning effect of the filter cartridge 3.

[0024] Furthermore, a drain pipe 8 and a discharge pipe 7 are respectively connected at the bottom of the heating tank 1 and the bottom of the filter cartridge 3. A solenoid valve is installed at the inlet end of the discharge pipe 7 to facilitate blocking the discharge outlet of the filter cartridge 3 to prevent materials from entering the discharge pipe 7 during the stirring process. The drain pipe 8 is used to discharge moisture in the heating tank 1; a discharge assembly 9 is installed in the discharge pipe 7 to facilitate preventing material blockage. The discharge assembly 9 includes a second pulley 91. Two sealed bearings are sleeved on the outer ring surfaces of the upper and lower parts of the discharge pipe 7. The second pulley 91 is sleeved on the outer ring surfaces of the two sealed bearings. The sealed bearings assist the second pulley 91 to seal the discharge port of the filter cartridge 3. When the pulley 91 rotates, direct leakage between the upper and lower parts of the discharge pipe 7 is avoided. The belt 45 is also sleeved in the transmission groove of the second pulley 91, so that the second pulley 91 can be driven to rotate through the first rotating shaft 42; the cross bar 92 is fixedly mounted on the inner surface wall of the second pulley 91, and the top of the second rotating shaft 93 is fixedly connected to the bottom of the cross bar 92. The auger 94 is sleeved on the outer ring surface of the second rotating shaft 93, so that it can be driven to rotate through the second pulley 91. The auger 94 in the rotating state can speed up the discharge speed of the material in the discharge pipe 7, avoid the accumulation and blockage of the material, and hinder the discharge work.

[0025] Furthermore, a top cover 10 is arranged at the top opening of the heating tank 1, and a feed pipe 11 is fixedly installed on the top wall of the top cover 10, so as to facilitate the introduction of materials into the filter cylinder 3. An exhaust port is opened on the top wall of the top cover 10, and an exhaust valve 12 is fixedly installed at the top of the exhaust port, so as to facilitate the pressure relief in the heating tank 1 to avoid high pressure affecting the drying process of the material.

[0026] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
