Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a low-carbon and energy-saving water filtration device. Background Technology

[0002] Water filtration devices utilize porous filtration structures to achieve solid-liquid separation. During actual operation, as filtration time accumulates, the surface of the filter structure and the interior of the filter pores gradually become clogged with solid impurities. This phenomenon is particularly pronounced when the water contains high levels of solid impurities, significantly shortening the lifespan of the filter structure. Existing solutions face two main technical challenges: firstly, failure to replace clogged filter structures promptly will severely impact the device's filtration efficiency; secondly, frequent replacement of filter structures increases downtime, ultimately reducing the overall processing efficiency of the device.

[0003] To address the aforementioned issues, existing technologies have proposed automatic cleaning solutions for filter structures. For example, Chinese patent CN218485330U discloses a cleaning device for wastewater treatment filters, which attempts to extend the filter's lifespan through mechanical cleaning by installing an electrically driven brush cleaning mechanism above the filter screen. However, this solution has significant technical drawbacks: firstly, brush cleaning only removes impurities from the filter screen surface, with limited effectiveness in clearing blockages inside the filter pores; secondly, during cleaning, the brush exerts downward pressure on impurities within the filter pores, potentially causing impurities to penetrate the filter screen and resulting in secondary water pollution. Therefore, while existing technologies improve treatment efficiency to some extent, they struggle to maintain optimal filtration performance, thus requiring a solution. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, this utility model provides a low-carbon and energy-saving water filtration device. By optimizing the impurity interception mechanism, it effectively removes most of the solid impurities before the sewage enters the main filter screen, thereby significantly improving the overall performance of the water filtration device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A low-carbon and energy-saving water filtration device includes a filter box and a pre-treatment cylinder with a downward-sloping front section and a wastewater receiving rear section. The upper rear section of the pre-treatment cylinder has an inlet, and the lower front section of the pre-treatment cylinder has an outlet pointing towards the filter box inlet. A conical filter screen with its conical end facing inward is coaxially rotated within the inner cavity of the front end of the pre-treatment cylinder. The outer edge of the conical filter screen is in contact with the inner circumference of the pre-treatment cylinder. The upper front section of the pre-treatment cylinder has a slag outlet for the conical filter screen to centrifugally remove impurities.

[0007] As a further embodiment of this utility model: the conical filter screen is coaxially rotated with the pre-treatment cylinder via a power shaft; a water wheel is coaxially fixed on a section of the power shaft near the inlet, and the water wheel is impacted by the sewage entering through the inlet and generates a rotating motion.

[0008] As a further embodiment of this utility model: a baffle is fixed to the outer edge of the conical surface of the conical filter screen, the baffle is arranged along the inclined direction of the conical filter screen, and the two ends of the baffle extend to the outer edge of the conical end and the round end of the conical filter screen, respectively.

[0009] As a further improvement of this utility model, the baffle is configured as at least two baffles evenly distributed around the axis of the conical filter screen.

[0010] As a further improvement of this utility model, a splash guard is arranged on the edge of the water inlet.

[0011] As a further improvement of this utility model, an impurity collection box communicating with the slag outlet is arranged on the outer periphery of the pretreatment cylinder.

[0012] As a further embodiment of this utility model: the inner cavity of the impurity collection box is a cylindrical structure coaxial with the pre-treatment cylinder, and the inner diameter of the impurity collection box is larger than the outer diameter of the pre-treatment cylinder.

[0013] As a further improvement of this utility model, a slag removal door that can be opened is installed on the outer wall of the impurity collection box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application involves adding a pre-treatment cylinder to the existing filter box to pre-intercept impurities before wastewater enters the filter box. Furthermore, the pre-treatment cylinder's impurity interception method is not simply adding a layer of filter screen on top of the main filter screen, but rather using centrifugal force during the rotation of the conical filter screen to remove impurities, thus achieving automatic cleaning of the conical filter screen. Compared to simply adding filter screens, manual cleaning of the conical filter screen is unnecessary, reducing the workload for staff and significantly improving the overall performance of the water filtration device.

[0016] 2. The water turbine is driven to rotate by the power and gravitational potential energy generated during the sewage transport process, which constitutes the power unit that drives the cone filter screen to rotate. There is no need to install a motor or manually drive the power shaft, which significantly reduces energy consumption and fully reflects the design concept of low carbon and energy saving.

[0017] 3. By designing the baffle strip, the contact area between the conical filter screen and the fixed impurities is increased, so that when the fixed impurities are at the bottom of the conical filter screen, they can better adhere to the conical filter screen and rotate synchronously with the conical filter screen. This allows the solid impurities to be better transported to the top of the conical filter screen and discharged outward by centrifugation.

[0018] 4. The edge of the water inlet is equipped with a splash guard to prevent sewage from splashing during the impact of sewage with the water wheel.

[0019] 5. An impurity collection box connected to the slag outlet is arranged on the outer periphery of the pretreatment cylinder to prevent solid impurities discharged from the slag outlet from splashing and to collect the solid impurities in a concentrated manner.

[0020] 6. The cylindrical inner cavity design of the impurity collection box allows impurities to slide down the inner cavity wall centrifugally when they splash onto it, preventing them from remaining above the slag outlet and falling back into the pretreatment cylinder.

[0025] 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.

[0026] For ease of understanding, the specific structure and working method of this utility model are further described below with reference to the accompanying drawings:

[0027] The specific structure of this utility model is as follows: Figure 1-3As shown, its main structure includes a filter box 10 and a pre-treatment cylinder 30 with a downward-sloping front section and a rear section for receiving sewage. The upper rear section of the pre-treatment cylinder 30 has an inlet 33, and the lower front section of the pre-treatment cylinder 30 has an outlet 32 ​​pointing towards the inlet of the filter box 10. The filter box 10 is a common filtration structure in the prior art, with a sewage inlet and outlet, and a filter screen arranged between the inlet and outlet. The specific construction is prior art and will not be described in detail here. This application is based on the existing filter box 10, and adds a pre-treatment cylinder 30 to pre-treat the sewage before it enters the inlet of the filter box 10, and then transports the pre-treated sewage to the inlet of the filter box 10 for filtration.

[0028] Specifically, such as Figure 1 As shown, a conical filter screen 40 with its cone end facing inward is coaxially rotated within the front end cavity of the pretreatment cylinder 30. The outer edge of the conical filter screen 40 is attached to the inner circumference of the pretreatment cylinder 30. The upper part of the front end of the pretreatment cylinder 30 has a slag outlet 34 for the conical filter screen 40 to centrifugally eject impurities. During operation, the sewage entering the rear cavity of the pretreatment cylinder 30 through the inlet 33 flows towards the front end of the pretreatment cylinder 30. The water in the sewage is filtered by the conical filter screen 40 and then discharged into the filter box 10 through the inlet 33 at the lower front end of the pretreatment cylinder 30. At the same time, the conical filter screen 40 rotates, and solid impurities in the sewage adhere to the conical surface of the conical filter screen 40 under the action of water flow. This causes the solid impurities in the sewage in the pretreatment cylinder 30 to undergo centrifugal motion along with the conical surface of the conical filter screen 40 and be centrifugally ejected outward through the slag outlet 34. This reduces the amount of solid impurities entering the filter box 10, significantly reduces the pressure on the filter box 10, ensures that the filter screen of the filter box 10 maintains a good filtration effect after long-term operation, reduces the replacement frequency of the filter screen of the filter box 10, and improves the overall performance of the water filtration device.

[0029] It is worth mentioning that the fixed impurity interception method of the pre-treatment cylinder 30 in this application is not simply adding a filter screen on top of the main filter screen of the filter box 10, but rather using centrifugal force during the rotation of the conical filter screen 40 to remove impurities, thereby achieving automatic cleaning of the conical filter screen 40. Compared with the method of simply adding filter screens, there is no need to manually clean the conical filter screen 40, reducing the extra workload of the staff.

[0030] Based on the above, such as Figure 1As shown, the conical filter screen 40 is coaxially rotated with the pretreatment cylinder 30 via a power shaft 60. A water wheel 50 is coaxially fixed to a section of the power shaft 60 near the inlet 33. The water wheel 50 is rotated by the impact of the sewage entering through the inlet 33. The rotation of the water wheel 50 is driven by the power generated during the sewage transport process and by gravitational potential energy. This constitutes the power unit that drives the conical filter screen 40 to rotate. There is no need to install a motor or manually drive the power shaft 60, which significantly reduces energy consumption and fully embodies the design concept of low carbon and energy saving.

[0031] Based on the above, such as Figure 1 As shown, a baffle 41 is fixed to the outer edge of the conical surface of the conical filter 40. The baffle 41 is arranged along the inclined direction of the conical filter 40, and its two ends extend to the outer edges of the conical end and the round end of the conical filter 40, respectively. By designing the baffle 41, the contact area between the conical filter 40 and the fixed impurities is increased. Preferably, the baffle 41 is set to at least two baffles evenly distributed around the axis of the conical filter 40, so that when the fixed impurities are at the lower part of the conical filter 40, they can better adhere to the conical filter and rotate synchronously with the conical filter 40, thereby allowing the solid impurities to be better transported to the upper part of the conical filter 40 and discharged outward by centrifugal force.

[0032] Furthermore, such as Figure 1-3 As shown, a splash guard 31 is arranged on the edge of the inlet 33 to prevent sewage from splashing during the impact of sewage with the water wheel 50.

[0033] Based on the above, such as Figure 2 and Figure 3 As shown, the outer periphery of the pretreatment cylinder 30 is provided with an impurity collection box 20 that communicates with the slag outlet 34, which is used to prevent solid impurities discharged from the slag outlet 34 from splashing and to collect the solid impurities in a concentrated manner.

[0034] Furthermore, such as Figure 3 As shown, the inner cavity of the impurity collection box 20 is a cylindrical structure coaxial with the pretreatment cylinder 30, and the inner diameter of the impurity collection box 20 is larger than the outer diameter of the pretreatment cylinder 30. The cylindrical inner cavity design of the impurity collection box 20 allows impurities to slide centrifugally downwards along the inner wall when they splash onto it, preventing them from remaining above the slag outlet 34 and repeatedly falling into the pretreatment cylinder 30.

[0035] In addition, such as Figure 2 As shown, the outer wall of the impurity collection box 20 is equipped with a slag removal door 21 that can be opened to clean the fixed impurities collected in the impurity collection box 20.

[0036] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention.
