Description

Technical Field

[0001] This utility model relates to the field of drum screen technology, and in particular to a drum screen for wetting towers used in the wetting and powdering of building ceramics. Background Technology

[0002] The powder produced by the wetting tower for building ceramics lacks fluidized bed curing treatment. After the powder particles are wetted, complete penetration takes time. During production, the particles, still wetted and spread out, easily stick together and accumulate. Conventional drum screens encounter problems with material sticking to the screen walls during this time, leading to blockages and failing to meet timely screening requirements.

[0003] Therefore, there is an urgent need for a drum screen for wetting towers used in the wetting and powdering of building ceramics to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0004] The purpose of this invention is to provide a drum screen for wetting towers used in the wetting and powdering of building ceramics, in order to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides a drum screen for a wetting tower for wetting and powdering building ceramics, including a shell, a powder collecting cone connected to the bottom of the shell, the shell being fixedly installed by a bracket, a feed hopper installed on one side of the shell, a screen cylinder rotatably connected inside the shell, the screen cylinder being located above the powder collecting cone, the end of the screen cylinder being connected to the bottom of the feed hopper, a drive shaft being provided at the center of the screen cylinder, the drive shaft being connected to an external drive component, two sets of support members being installed on the drive shaft, the support members being used to support the screen cylinder, the support members being located inside the screen cylinder, the powder collecting cone being formed by two opposing parallel end faces and two opposing inclined side faces, the drive shaft being axially perpendicular to the top edge of the two inclined side faces of the powder collecting cone.

[0006] Optionally, the support member includes a plurality of support rods fixedly connected to the drive shaft, and a support crossbar is fixedly connected to one end of the support rod away from the drive shaft. The support crossbar is fixedly connected to the inner wall of the screen cylinder.

[0007] Optionally, the support column is fitted with several impact steel rings.

[0008] Optionally, the inner wall of the screen cylinder is provided with several annular clamp seats, the clamp seats are fixedly connected to the supporting crossbar, and several fixing strips are provided on the outer side of the clamp seats. The fixing strips are in contact with the outer wall of the screen cylinder. Both the fixing strips and the clamp seats are provided with several round holes, and the clamp seats and the fixing strips are fixedly connected by bolts passing through the round holes.

[0009] Optionally, the outer shell has a feed inlet, the feed hopper is located at the feed inlet, the feed inlet is fan-shaped, and the feed inlet is adapted to the diameter of the screen cylinder.

[0010] Optionally, partition frames are installed on both sides of the outer casing, and the partition frames are fixedly connected to the bracket.

[0011] Optionally, the top of the housing may be detachably connected to a movable flat top.

[0012] This utility model discloses the following technical effects: During use, the conveyor belt under the wetting tower is directly connected to the feed hopper. The powder falls from the feed hopper into the screen cylinder. An external drive unit drives the transmission shaft to rotate, which in turn drives the support to rotate, thus rotating the screen cylinder. The screen cylinder sieves the powder during rotation. The transmission shaft inside the screen cylinder is perpendicular to the long side of the powder collecting cone to solve the problem of powder being thrown directly onto the side plate of the powder collecting cone and accumulating when the screen cylinder rotates. This allows sufficient space for the powder to fall freely onto the conveyor belt below the powder collecting cone. Based on the characteristics of the powder produced by the wetting tower, this utility model changes the traditional cylinder structure of the drum screen. The powder collecting cone is designed laterally, and the axial side plate space is increased to about half the cylinder diameter, completely solving the problem of powder falling and sticking to the side wall. Furthermore, the support is located far from the feed hopper, causing the powder to tumble and fall onto the suspended screen cylinder, preventing it from falling onto the support and solving the problem of powder impacting and accumulating on the support.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Reference Figures 1 to 4 As shown, this embodiment provides a drum screen for a wetting tower for wetting and powdering building ceramics, including a shell 1. The bottom of the shell 1 is connected to a powder collecting cone 5. The shell 1 is fixedly installed by a bracket 6. A feed hopper 3 is installed on one side of the shell 1. A screen cylinder 7 is rotatably connected inside the shell 1. The screen cylinder 7 is located above the powder collecting cone 5. The end of the screen cylinder 7 is connected to the bottom of the feed hopper 3. A drive shaft 12 is set at the center of the screen cylinder 7. The drive shaft 12 is connected to an external drive component. Two sets of support components are installed on the drive shaft 12. The support components are used to support the screen cylinder 7. The support components are located inside the screen cylinder 7. The powder collecting cone 5 is formed by two opposite parallel end faces and two opposite inclined side faces. The drive shaft 12 is axially perpendicular to the top edge of the two inclined side faces of the powder collecting cone 5.

[0022] In operation, the conveyor belt at the bottom of the wetting tower is directly connected to the feed hopper 3. Powder falls from the feed hopper 3 into the screen cylinder 7. An external drive unit rotates the transmission shaft 12, which in turn rotates the support component, thus rotating the screen cylinder 7. The screen cylinder 7 sieves the powder as it rotates. The transmission shaft 12 inside the screen cylinder 7 is perpendicular to the long side of the powder collecting cone 5. This design prevents the powder from being thrown off the screen and directly adhering to the side plate of the powder collecting cone 5, allowing it sufficient space to fall freely onto the conveyor belt below the cone 5. Based on the characteristics of the powder produced by the wetting tower, this invention changes the traditional cylinder structure of the drum screen. The powder collecting cone 5 is designed laterally, and the axial side plate space is increased to approximately half the cylinder diameter, completely solving the problem of powder falling and adhering to the side wall. Furthermore, the support component is positioned away from the feed hopper 3, causing the powder to tumble and fall onto the suspended screen cylinder 7, preventing it from falling onto the support component and solving the problem of powder impacting and adhering to the support component.

[0023] Furthermore, the feed hopper 3 is in the shape of a sieve, with axial feeding. The bottom of the feed hopper 3 is close to the drive shaft 12, and the end does not exceed the edge of the cylinder. The width is half the cylinder diameter, and the upper end is connected to the conveyor belt of the wetting tower for material discharge.

[0024] Furthermore, the sieve cylinder 7 is made of 1-2 mesh coarse stainless steel mesh, and the outer shell 1 and the powder collecting cone 5 are made of high-density non-stick PE polymer board.

[0025] Specifically, four columns are designed according to the diameter of the drum screen 7, and three cross bearings are designed at the die-side of the drive shaft 12. The lower die cross bearing is located at the bottom of the drum, the middle die cross bearing is mounted on a bearing seat to support the drive shaft 12, and the upper die cross bearing is 200mm higher than the highest point of the drum 7 with an inclination of less than 7 degrees. The upper, middle and lower cross bearings are welded together with extension rods to form a square frame structure, creating a space for the rotating powder in the drum 7 to fall freely without hitting the walls.

[0026] Further refining the scheme, the support components include several support rods 13 fixedly connected to the drive shaft 12, and a support crossbar 10 fixedly connected to one end of the support rod 13 away from the drive shaft 12. The support crossbar 10 is fixedly connected to the inner wall of the screen cylinder 7.

[0027] Specifically, the feed end support rod 13 is moved inward by about 300mm so that the material conveyor belt does not stick to the support rod 13 when it is sent down in a parabolic fashion.

[0028] The design was further refined, with several impact steel rings 14 fitted onto the support pole 13.

[0029] Specifically, when the screen cylinder 7 rotates, it impacts the steel ring 14 times, which repeatedly moves up and down to generate impact, thus vibrating the screen to clean the mesh holes.

[0030] Further refining the scheme, the inner wall of the screen cylinder 7 is provided with several annular clamp seats 11, the clamp seats 11 are fixedly connected to the supporting crossbar 10, and several fixing strips 9 are provided on the outer side of the clamp seats 11. The fixing strips 9 are in contact with the outer wall of the screen cylinder 7. Several round holes 15 are provided on both the fixing strips 9 and the clamp seats 11. The clamp seats 11 and the fixing strips 9 are fixedly connected by bolts passing through the round holes 15.

[0031] Specifically, the support uprights 13 are designed as eight, divided into two groups and welded to the drive shaft 12. The support crossbars 10 are designed as eight. The ends of the support uprights 13 are welded to the support crossbars 10. The ends and center of the crossbars are welded with clamp seats 11 to facilitate clamping the mesh. The support uprights 13 at the feed end are displaced inward by 300mm to form a powder drop zone. Before welding the support uprights 13, impact steel rings 14 are installed.

[0032] Further refining the design, the outer shell 1 has an inlet 8, the feed hopper 3 is located at the inlet 8, the inlet 8 is fan-shaped, and the diameter of the inlet 8 is matched with that of the screen cylinder 7.

[0033] Specifically, the feed hopper 3 is installed at an angle greater than 60 degrees, with its lower end close to the drive shaft 12, and its width is not less than half the cylinder diameter. The outer shell 1 is provided with a screen discharge port on the side away from the feed hopper 3, with the screen discharge port angle greater than 60 degrees and the upper end designed as an arc shape, which is one-quarter of the cylinder diameter.

[0034] To further refine the design, partition frames 4 are installed on both sides of the outer shell 1, and the partition frames 4 are fixedly connected to the bracket 6.

[0035] Further refining the design, the top of the outer casing 1 is detachably connected to a movable flat top 2.

[0036] Specifically, the top of the outer casing 1 is designed with a movable flat top 2 for maintenance and observation. The outer casing 1 consists of upright side panels, the dust collecting cone 5 consists of inclined plates, and the lower end of the dust collecting cone 5 is connected to a sealing dustproof skirt.
