Description

Technical Field

[0001] This utility model relates to the field of water distribution trough equipment, specifically a stirring device for a water distribution trough on an inclined screen. Background Technology

[0002] Inclined screens allow fluid materials to flow into an arc-shaped screen. Relying on the gravity of the water flow, solids and liquids are separated during relative shearing motion with the screen grid, achieving the purpose of filtration. Solids that accumulate on the screen will roll down with the help of the liquid flow, while the liquid continuously washes the screen grid with water force, enabling it to perform a self-cleaning function. This completes the entire process of continuous self-cleaning of the screen and continuous collection of solids.

[0003] Liquids stored in water distribution tanks require screening. Over time, liquids tend to accumulate sediment, resulting in localized deposits of solid particles. Directly feeding the liquid into the screening process can cause localized accumulation on the screen, affecting screening quality and necessitating secondary screening, which reduces screening efficiency.

[0018] 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.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diagram illustrates a water tank agitation device on an inclined screen, comprising a water tank 1. An agitation structure 2 is installed inside the water tank 1. The agitation structure 2 includes two main shafts 201 arranged side-by-side and parallel to each other. Both ends of the main shafts 201 are rotatably connected to the two sides inside the water tank 1. Several evenly arranged sleeves 204 are fixedly fitted onto the outer wall of the main shafts 201. Helical blades 202 are fixedly connected to the outer wall of the sleeves 204 and arranged in a ring. The helical blades 202 on the two main shafts 201 are staggered. Several sets of stirring blades 203 are fixedly connected to the outer wall of the main shafts 201, with each set containing three stirring blades 203 arranged in a ring. The stirring blades 203 and the helical blades 202 are staggered. A drive structure 3 is installed on the outer side of the water tank 1, and a valve plate structure 4 is installed at the bottom of the water tank 1.

[0020] It is worth noting that the motor 302 drives the gear 303 to rotate. The two gears 303 mesh, and the rotation of the gears 303 drives the main shaft 201 to rotate inside the water tank 1. The rotation of the main shaft 201 drives the spiral blade 202 and the stirring blade 203 to rotate. The two main shafts 201 rotate synchronously and in opposite directions, stirring the liquid inside the water tank 1. The rotation of the spiral blade 202 stirs the liquid inside the water tank 1 in a horizontal direction, while the synchronous rotation of the stirring blade 203 mixes the liquid in a vertical direction, improving the mixing uniformity and reducing liquid sedimentation. The mixing of solid particles and liquid is made uniform through stirring, preventing regional sedimentation that could affect the subsequent screening quality and efficiency. The mixing and stirring can be carried out in both horizontal and vertical directions, thus improving the mixing efficiency.

[0021] Please see Figure 2 The drive structure 3 includes a motor 302, one end of the main shaft 201 rotates through the side of the water tank 1, and the through end is connected to a gear 303. The two gears 303 mesh with each other, and the meshing of the gears 303 drives the two main shafts 201 to rotate synchronously. It does not require the use of too many motors 302, thus reducing equipment costs and electricity costs.

[0022] Please refer to Figure 2 and Figure 4The length of the stirring blade 203 is less than the distance between the two main shafts 201, ensuring that the stirring blade 203 does not collide with the main shaft 201 during rotation. The main shaft 201 is fitted with a collar 206 near the center position. A support plate 205 is fixedly connected to the outer side wall of the collar 206. The other side of the support plate 205 is fixedly connected to the adjacent side inside the water tank 1, so that the main shaft 201 can be stably supported near the center position, effectively preventing the risk of shaking and breakage that may occur during rotation due to the excessive length of the main shaft 201.

[0023] See Figure 1 The water tank 1 is fixedly connected to the sleeve 301 on the outer side of the gear 303. The main shaft 201 is set inside the sleeve 301 through end. The gear 303 is located inside the sleeve 301 and meshes and rotates inside the sleeve 301, reducing the possibility of foreign objects being caught in the meshing position and ensuring safety.

[0024] See Figure 3 and Figure 5 The valve plate structure 4 includes a hydraulic cylinder 401 and a baffle 402. Several support rods 5 are fixedly connected to the bottom of both sides of the water tank 1. A long channel is opened at the bottom of the water tank 1. A matching baffle 402 is provided at the position of the long channel. A long rubber pad 403 is fixedly connected to the top of the baffle 402. The bottom of the baffle 402 is rotatably connected to the bottom of the water tank 1 through several hinges 404. The tail ends of the two inclined hydraulic cylinders 401 are fixedly connected to a first clamping plate 405. The bottom ends of both ends of the baffle 402 are fixedly connected to a second clamping plate 407. The first clamping plate 405 is rotatably connected to the adjacent support rod 5 through a pin 406. The second clamping plate 407 is rotatably connected to the output end of the hydraulic cylinder 401 through a pin 406.

[0025] It is worth noting that a hydraulic system is installed around the water tank 1 to control the synchronous opening of two hydraulic cylinders 401, which allows the baffle 402 to rotate open or close, so that the liquid in the water tank can be released or stored normally. The long rubber pad 403 is elastic, which increases the sealing of the long channel and reduces the possibility of liquid leakage.

[0026] See Figure 1 The support rod 5 has a long cavity 501 on the side at the bottom end. The long cavity 501 is designed to allow the support rod 5 to be installed on the screen equipment above by bolts.

[0027] Working principle: Driven by motor 302, gear 303 begins to rotate. Since the two gears 303 mesh with each other, when one gear 303 rotates, it drives the other gear 303 to rotate in the opposite direction. These two gears 303 are respectively connected to one end of the two main shafts 201, so the main shafts 201 also begin to rotate, and the two main shafts 201 rotate in opposite directions. As the main shafts 201 rotate, the sleeve 204 fixedly sleeved on the outer wall of the main shaft 201, as well as the spiral blades 202 and stirring blades 203 on it, also rotate. The spiral blades 202 are staggered on the two main shafts 201, and their rotation will push the liquid inside the water tank 1 to stir horizontally; at the same time, the rotation of the stirring blades 203 will mix the liquid vertically. This improves the uniformity of mixing. The length of the stirring blade 203 is less than the distance between the two main shafts 201, which ensures that the stirring blade 203 will not collide with the main shaft 201 during the rotation and stirring process. In addition, a collar 206 and a support plate 205 are provided near the center of the main shaft 201, which provide stable support for the main shaft 201 and effectively prevent the risk of shaking and breakage that may occur during rotation due to the excessive length of the main shaft 201. When it is necessary to discharge or store the liquid in the water tank 1, the two hydraulic cylinders 401 can be opened simultaneously by the control system. The extension and retraction of the hydraulic cylinders 401 will drive the baffle 402 to rotate to open or close the long channel. The setting of the long rubber pad 403 increases the sealing of the long channel and reduces the possibility of liquid leakage.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
