Description

Technical Field

[0001] This utility model belongs to the field of steel pipe flushing technology, specifically relating to a flushing water filtration device. Background Technology

[0002] In the steel pipe production process, the rinsing process is a crucial step in preventing oxidation and removing surface scale. Vigorous rinsing with flushing water effectively removes surface impurities, ensuring pipe quality. However, the rinsing process generates a large amount of sediment. If this sediment is not treated promptly, it can not only clog pipes but also degrade the quality of the flushing water, affecting the rinsing effect and ultimately reducing steel pipe production efficiency and product quality. Existing flushing water filtration methods have many shortcomings. For example, sediments are mostly scattered at the bottom of the filtration device, lacking a targeted collection and guidance structure, making it difficult to achieve centralized collection. This results in the need to thoroughly clean the entire bottom of the device during cleaning, which is cumbersome and inefficient. At the same time, the scattered sediments are prone to forming dead corners in the device, further increasing the difficulty of manual cleaning. Utility Model Content

[0003] The purpose of this utility model is to provide a flushing water filtration device to solve the problems of debris scattering and being difficult to collect, and the cumbersome cleaning of existing steel pipe flushing water filtration devices.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flushing water filtration device, comprising an outer tank, an inner tank disposed inside the outer tank, the openings of the outer tank and the inner tank being arranged in opposite directions, the top of the inner tank being conical, a water outlet pipe connected to the bottom of the inner cavity of the outer tank, a collection ring connected to the bottom of the outer tank, the center of the bottom surface of the inner cavity of the outer tank being higher than the periphery, a water inlet ring pipe disposed on the collection ring, a plurality of water outlet nozzles connected to the bottom of the water inlet ring pipe, and a filter screen plate disposed inside the water outlet pipe.

[0005] Furthermore, the two sides of the inner tank are connected to the inner wall of the outer tank via connecting rods.

[0006] Furthermore, the top of the water outlet pipe is located inside the inner tank, and the top of the water outlet pipe is higher than the opening of the inner tank.

[0007] Furthermore, a drain pipe is provided on the collection ring, and a valve is provided on the drain pipe.

[0008] Furthermore, several of the water nozzles are arranged in a rotationally symmetrical and tilted manner, with the water outlets of the several water nozzles aligned with the bottom of the inner cavity of the collection ring.

[0009] Furthermore, several of the water nozzles are arranged in an isosceles trapezoidal shape.

[0010] Furthermore, vertical grooves are provided on both sides of the bottom of the water outlet pipe cavity, and the top of the vertical grooves are connected to the annular groove on the water outlet pipe cavity. Protrusions are provided on both sides of the filter plate, and the protrusions are adapted to the vertical grooves.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This flushing water filtration device guides sediment to slide directionally down the conical and inclined surfaces to the annular collection ring through the inclined bottom surface of the outer tank and the conical top structure of the inner tank, solving the problem of scattered accumulation. The integrated design of the collection ring and the drain pipe enables centralized collection and rapid discharge of sediment, avoiding thorough cleaning. At the same time, the water inlet ring pipe with inclined nozzles at the bottom of the collection ring sprays planar water flow to flush out dead corners after the machine stops, washing away attached impurities to the vicinity of the drain pipe, thoroughly eliminating the risk of accumulation, significantly improving cleaning efficiency and reducing the difficulty of manual operation.

[0014] The present invention will be further described below with reference to the embodiments.

[0015] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0016] Please see Figure 1-4 This utility model provides a flushing water filtration device, including an outer tank 10, and an inner tank 20 is provided inside the outer tank 10.

[0017] The outer tank 10 has its opening facing upwards, and the inner tank 20 has its opening facing downwards. The two sides of the inner tank 20 are connected to the inner wall of the outer tank 10 via connecting rods 210. The top of the inner tank 20 is conical, which facilitates the sliding of debris from the top of the inner tank 20.

[0018] The bottom of the inner cavity of the outer tank 10 is connected to a water outlet pipe 30. The top of the water outlet pipe 30 is located inside the inner tank 20, and the top of the water outlet pipe 30 is higher than the opening of the inner tank 20. This arrangement allows the flushing water to flow in an "S" shape.

[0019] The bottom of the outer can 10 is connected to a collection ring 110. The bottom surface of the inner cavity of the outer can 10 is high in the center and low around the perimeter, so that debris will slide down to the bottom of the outer can 10 and enter the interior of the collection ring 110.

[0020] The collection ring 110 is equipped with a drain pipe 111, and a valve is installed on the drain pipe 111 to open or close the drain pipe 111. The collection ring 110 is equipped with a water inlet ring pipe 120, and the bottom of the water inlet ring pipe 120 is connected to several water outlet nozzles 121. The several water outlet nozzles 121 are arranged in a rotationally symmetrical and inclined manner, and the water outlets of the several water outlet nozzles 121 are aligned with the bottom of the inner cavity of the collection ring 110. The several water outlet nozzles 121 are arranged in an isosceles trapezoidal shape, which can better spray water out in a plane to rinse the inner cavity of the collection ring 110.

[0021] Vertical grooves 301 are provided on both sides of the bottom of the water outlet pipe 30. The top of the vertical grooves 301 are connected to the annular groove 302 on the inner cavity of the water outlet pipe 30. A filter plate 310 is provided in the annular groove 302. Protrusions 311 are provided on both sides of the filter plate 310. The protrusions 311 are adapted to the vertical grooves 301. When the filter plate 310 is installed, the protrusions 311 are aligned with the vertical grooves 301 and pushed in. After the filter plate 310 enters the annular groove 302, the filter plate 310 is rotated. At this time, the filter plate 310 will not detach from the water outlet pipe 30. The filter plate 310 further filters lighter impurities in the water.

[0022] The working principle and usage process of this utility model are as follows: Rinse water flows in from the top opening of the outer tank 10. Guided by the inverted inner tank 20 and its conical top structure, heavier debris automatically slides down the conical surface and collects in the annular collection ring 110 via the inclined bottom surface (high in the middle and low around the edges) of the outer tank 10. Simultaneously, the rinse water flows downward through the annular space between the inner tank 20 and the outer tank 10, then turns back upward into the inner tank 20. Lighter impurities are then filtered through the filter screen 310 in the outlet pipe 30 before being discharged. During continuous rinsing, newly generated debris continuously settles into the collection ring 110 with the water flow, while existing debris in the collection ring 110 is temporarily stored at the bottom due to the closed drain pipe 111, forming a dynamic separation process of "directional aggregation of impurities and orderly discharge of clean water."

[0023] After the device is stopped, first open the drain pipe 111 valve. Utilize the guiding effect of the inclined surface at the bottom of the outer tank to automatically discharge the debris accumulated in the collection ring 110 with the residual flushing water. After the debris is basically emptied, close the drain pipe 111 valve and inject cleaning liquid (such as clean water) into the collection ring 110 through the inlet ring pipe 120. At this time, several symmetrically inclined water nozzles 121 at the bottom of the inlet ring pipe 120 simultaneously spray planar water flow, flushing the attached stubborn impurities to the vicinity of the drain pipe 111. Finally, open the drain pipe 111 valve again to completely discharge the flushed sewage and residue, completing the cleaning and maintenance of the collection ring 110.

[0024] 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.
