Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, specifically to a device for filtering coarse impurities in premixed concrete. Background Technology

[0002] Ready-mixed concrete refers to a concrete mixture made by mixing cement, aggregates, water, and admixtures and additives in a certain proportion at a batching plant, and then transporting it to the place of use within a specified time using a mixer truck. In order to ensure the quality of ready-mixed concrete, coarse impurities need to be filtered out during the processing of ready-mixed concrete.

[0003] Traditional filtration equipment uses filter screens or sieves for filtration. This filtration method relies on gravity or slow water flow to make concrete pass through the filter screen and filter out impurities. However, due to the limited filtration area of ​​the filter screen and the high viscosity of the concrete itself, the filtration speed is very slow, which affects the filtration efficiency of the concrete. Utility Model Content

[0008] Preferably, the filter cylinder is provided with a stirring rod inside, one end of which is rotatably connected to the inner wall of the filter cylinder, and the other end of which is fixedly connected to the feed pipe through a bracket.

[0009] By using the above technical solution, the mixing rod can be used to mix the concrete during the filtration process, thereby increasing the filtration efficiency.

[0010] Preferably, the outer surface of the filter cartridge is provided with a shielding structure, which forms a shield on the outer surface of the filter cartridge through an upper baffle and a lower baffle, making it easier to clean the filter cartridge.

[0011] By adopting the above technical solution, the shielding structure facilitates the cleaning process of the filter cartridge.

[0012] Preferably, the shielding structure includes an upper baffle, which is an arc-shaped plate structure. The two ends of the upper baffle are respectively fixedly connected to the surface of the support block and the inner wall of the outer shell. The upper baffle is positioned above the filter cylinder, and lower baffles of equal size are symmetrically arranged below the filter cylinder. The lower surface of the lower baffle is connected to the output end of the electric push rod, which is fixedly installed on the lower surface of the outer shell.

[0014] Preferably, a nozzle is provided through the surface of the upper baffle, and multiple nozzles are distributed in parallel on the surface of the upper baffle.

The connecting pipe is connected to a water inlet pipe, and the other end of the water inlet pipe penetrates the upper surface of the outer shell.

[0015] By adopting the above technical solution, the filter cartridge can be cleaned using a spray nozzle, thereby increasing the service life of the device.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This premixed concrete coarse impurity filtering device:

[0017] 1. This device has a rotating filter cylinder inside the outer shell. After the ready-mixed concrete is fed into the filter cylinder, the rotating filter cylinder performs centrifugal filtration on the ready-mixed concrete, thereby filtering impurities in the ready-mixed concrete more efficiently. Under the action of centrifugal force, the concrete is evenly distributed on the surface of the filter cylinder and fully contacts the filter holes, thereby improving the filtration speed.

[0019] 3. This device has an arc-shaped upper baffle and a lower baffle installed above and below the filter cartridge, respectively. The upper and lower baffles are connected by a flexible connector. The upper baffle is fixed in position, while the lower baffle can move vertically under the action of an electric push rod, realizing the switching between the filtration process and the cleaning process. When the upper and lower baffles come into contact, a closed space is formed on the outer surface of the filter cartridge. At this time, opening the nozzle can clean the filter cartridge and increase the service life of the equipment. Attached Figure Description

[0027] 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.

[0028] Please see Figures 1-6This utility model provides a technical solution: a premixed concrete coarse impurity filtration device, including a shell 1, a feed pipe 2, a discharge pipe 3, a support block 4, a filter cylinder 5, a motor 6, a stirring rod 7, an upper baffle 8, a lower baffle 9, an electric push rod 10, a connector 11, a nozzle 12, a connecting pipe 13, and a water inlet pipe 14.

[0029] The outer shell 1 is a horizontal cylindrical structure with a hollow interior. A feed pipe 2 is installed through one side surface of the outer shell 1, and a valve is installed inside the feed pipe 2. A discharge pipe 3 is installed through the lower surface of the outer shell 1, and a valve is installed inside the discharge pipe 3. A centrifugal filtration structure is installed inside the outer shell 1. The centrifugal filtration structure filters the ready-mixed concrete through a rotating filter cylinder 5. The centrifugal filtration structure includes a support block 4, which is cylindrical and fixedly installed on the side surface of the inner wall of the outer shell 1. A filter cylinder 5 is rotatably connected to the surface of the support block 4. The filter cylinder 5 is a hollow cylindrical structure with filter holes installed through its surface. The side surface of the filter cylinder 5 is connected through the feed pipe 2 and fixedly connected to the output end of a motor 6. The motor 6 is fixedly installed on the outer surface of the outer shell 1. A stirring rod 7 is installed inside the filter cylinder 5. One end of the stirring rod 7 is rotatably connected to the inner wall of the filter cylinder 5, and the other end of the stirring rod 7 is fixedly connected to the feed pipe 2 through a bracket.

[0030] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the valve inside the feed pipe 2 is opened, and the pre-mixed concrete is transported to the inside of the filter cylinder 5 through the feed pipe 2. The motor 6 is started, and the motor 6 drives the filter cylinder 5 to rotate. During the rotation of the filter cylinder 5, the stirring rod 7 installed inside the filter cylinder 5 remains stationary because it is fixedly connected to the feed pipe 2. Therefore, there is an interaction force between the rotating filter cylinder 5 and the stirring rod 7. The rotating filter cylinder 5 centrifugally filters the concrete in it. The filtered concrete falls through the filter holes on the surface of the filter cylinder 5 into the gap between the filter cylinder 5 and the lower baffle 9, and is discharged from the discharge pipe 3. During this process, the stirring rod 7 stirs the concrete as the filter cylinder 5 rotates, preventing the concrete from clogging the filter holes.

[0031] The outer surface of the filter cartridge 5 is provided with a shielding structure. The shielding structure forms a shield on the outer surface of the filter cartridge 5 through an upper baffle 8 and a lower baffle 9, which facilitates the cleaning of the filter cartridge 5. The shielding structure includes an upper baffle 8, which is an arc-shaped plate structure. The two ends of the upper baffle 8 are respectively fixedly connected to the surface of the support block 4 and the inner wall of the outer shell 1. The upper baffle 8 is located above the filter cartridge 5. Symmetrically arranged lower baffles 9 of the same size are arranged below the filter cartridge 5. The lower surface of the lower baffle 9 is connected to the output end of the electric push rod 10. The electric push rod 10 is fixedly installed on the lower surface of the outer shell 1. The upper baffle 8 and the lower baffle 9 together form a circular structure. The upper baffle 8 and the lower baffle 9 are connected by a connector 11, which is a flexible fabric structure. A pipe is installed through the surface of the lower baffle 9 and connected to the discharge pipe 3. A nozzle 12 is installed through the surface of the upper baffle 8. Multiple nozzles 12 are distributed in parallel on the surface of the upper baffle 8. Multiple nozzles 12 are connected to the same connecting pipe 13. The connecting pipe 13 is fixedly installed on the surface of the upper baffle 8. The connecting pipe 13 is connected to a water inlet pipe 14. The other end of the water inlet pipe 14 penetrates the upper surface of the outer shell 1.

[0032] like Figure 3 , Figure 4 and Figure 6 As shown, before filtration begins, the electric push rod 10 is activated, which drives the lower baffle 9 to descend. The lower baffle 9 descends and forms a gap with the surface of the filter cylinder 5. At this time, the upper baffle 8 and the lower baffle 9 are connected by a flexible connector 11. The filtered concrete falls onto the surface of the lower baffle 9 and is discharged from the discharge pipe 3. After filtration is completed, the electric push rod 10 is activated, which drives the lower baffle 9 to rise and contact the upper baffle 8. The upper baffle 8 and the lower baffle 9 form a closed space on the outer surface of the filter cylinder 5. The water inlet pipe 14 is connected to an external water source, and the nozzle 12 is turned on. The cleaning water washes away the impurities on the surface of the filter cylinder 5 and flushes the impurities inside the filter cylinder 5 out through the feed pipe 2.

[0033] Working principle: When using this premixed concrete coarse impurity filtering device, premixed concrete is injected into the filter cylinder 5 through the feed pipe 2. The motor 6 is started, and the motor 6 drives the filter cylinder 5 to rotate. The rotating filter cylinder 5 filters the concrete. The filtered concrete is discharged through the discharge pipe 3. When cleaning the filter cylinder 5 after filtration, the electric push rod 10 is started. The electric push rod 10 drives the lower baffle 9 to contact the upper baffle 8. The upper baffle 8 and the lower baffle 9 form a closed space on the outer surface of the filter cylinder 5. The nozzle 12 is opened to clean the filter cylinder 5, which increases the overall practicality.

[0034] 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.
