Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment equipment, specifically to a sewage treatment suspended solids separation device. Background Technology

[0002] The purpose of separating suspended solids in wastewater is to reduce the turbidity of wastewater by removing solid particles, colloids and other substances suspended in the water, thereby reducing the load on subsequent treatment processes; preventing suspended solids from clogging pipes and equipment, and ensuring the stable operation of the wastewater treatment system.

[0003] Wastewater treatment often uses filtration to separate suspended solids. Traditional equipment often uses flat filter screens or simple grids for interception. Suspended solids in wastewater tend to accumulate on the surface of the filter screen, resulting in a rapid reduction in filtration area, high clogging frequency, and the need for frequent cleaning. This increases operating costs and maintenance workload, and also reduces the efficiency of suspended solids separation.

[0004] Therefore, we need to propose a suspended solids separation device for wastewater treatment. Utility Model Content

[0005] The purpose of this invention is to provide a suspended solids separation device for wastewater treatment. The conical filter cover design utilizes the inertia of wastewater flow. When wastewater enters the separation chamber, the suspended solids are filtered by the filter cover and then guided along the conical surface to the separation port and enter the collection chamber. This avoids the large accumulation of suspended solids on the surface of the filter cover, effectively reduces the frequency of filter cover clogging, and reduces the number of times the filter cover needs to be cleaned, thereby reducing operating costs and maintenance workload, and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wastewater treatment suspended solids separation device, comprising:

[0008] The separation chamber has an opening at the top for sewage to enter and an outlet at the bottom for sewage to exit.

[0009] A separation structure is provided inside the separation chamber. The separation structure includes a cone-shaped filter cover, which is fixed inside the separation chamber. A collection chamber is provided on the outer wall of the separation chamber. A separation port is provided on the inner wall of the separation chamber, which is connected to the upper part of the inner cavity of the collection chamber. When the filter cover is fixed in the separation chamber, the separation port is located on the lower periphery of the filter cover and is flush with the lower end of the filter cover. When sewage enters the separation chamber, suspended solids are filtered by the filter cover and guided into the collection chamber through the separation port for collection.

[0010] Preferably, it also includes a filter port, which is disposed on the inner wall of the separation chamber. The filter port is located directly below the separation port and is connected to the lower part of the inner cavity of the collection chamber. A filter screen is disposed inside the filter port, and the suspended solids and wastewater entering the collection chamber flow back to the separation chamber through the filter port.

[0011] Preferably, it also includes a door, which is disposed on the outer wall of the collection chamber. The outer wall of the collection chamber has a notch, and an openable door is installed at the notch. When the door is closed, it seals with the notch. When the door is opened, the inside of the collection chamber can be cleaned.

[0012] Preferably, it also includes a support ring for supporting the filter cover, which is disposed on the inner wall of the separation chamber, and the bottom edge of the filter cover abuts against the support ring when the filter cover is placed in the separation chamber.

[0013] Preferably, it also includes a bracket disposed within the support ring. The bracket has a tapered design and is adapted to the inner wall of the filter cover. When the bracket is placed in the separation chamber, the outer wall of the top of the bracket abuts against the inner wall of the filter cover to further improve the support capacity of the filter cover.

[0014] Preferably, it also includes a fixing structure for fixing the filter cover, which is disposed on the top of the filter cover. The fixing structure includes a protrusion with a fixing hole.

[0015] The upper end of the bracket is provided with a protruding post, and a through hole is opened on the outer wall of the protruding post. When the filter cover is placed on the bracket, the protruding post is inserted into the inside of the protruding sleeve and the through hole and the fixing hole are aligned and locked by fixing screws, thereby avoiding the impact of sewage on the filter cover and causing the filter cover to shift.

[0016] Preferably, the filter also includes a diversion plate disposed on the outer wall of the filter cover. Multiple sets of diversion plates are disposed at equal intervals around the outer wall of the filter cover, and the filter screen on the filter cover is disposed between adjacent diversion plates. The diversion plate diverts the sewage to reduce the impact force while also strengthening it.

[0017] Preferably, it also includes a threaded sleeve disposed at the lower end of the outlet. The threaded sleeve is threadedly installed inside the outlet, and a second filter screen is installed inside the threaded sleeve for secondary filtration of sewage to improve the separation effect of suspended solids and sewage.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The conical filter cover design utilizes the inertia of sewage flow. When sewage enters the separation chamber, suspended solids are filtered by the filter cover and then guided along the conical surface to the separation port and enter the collection chamber. This avoids the large accumulation of suspended solids on the surface of the filter cover, effectively reducing the frequency of filter cover clogging and the number of times the filter cover needs to be cleaned, thereby reducing operating costs and maintenance workload.

[0020] 2. Due to the conical design of the filter cover and the timely guidance of suspended solids to the collection chamber, the effective filtration area of ​​the filter cover can remain large for a long time, allowing wastewater to pass through the filter cover more smoothly and improving the separation efficiency of suspended solids and wastewater. At the same time, the diversion plate diverts the wastewater, reducing the impact force of wastewater on the filter cover and allowing the wastewater to contact the filter cover more evenly, further improving the filtration effect.

[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 Figure 1-5 This utility model provides a technical solution:

[0029] A wastewater treatment suspended solids separation device, comprising:

[0030] Separation chamber 1 has an opening at the top for sewage to enter, and an outlet 3 at the bottom for sewage to be discharged.

[0031] The separation structure is located inside the separation chamber 1. The separation structure includes a cone-shaped filter cover 2, which is fixed inside the separation chamber 1. A collection chamber 5 is provided on the outer wall of the separation chamber 1. A separation port 4 is provided on the inner wall of the separation chamber 1, which is connected to the upper part of the inner cavity of the collection chamber 5. When the filter cover 2 is fixed in the separation chamber 1, the separation port 4 is located on the lower periphery of the filter cover 2 and is flush with the lower end of the filter cover 2. When sewage enters the separation chamber 1, suspended solids are filtered by the filter cover 2 and guided to the separation port 4 to enter the collection chamber 5 for collection.

[0032] Wastewater enters the separation chamber 1 through the top opening and flows downwards under gravity. The filter hood 2 in the separation structure filters the wastewater, intercepting suspended solids and guiding them into the separation port 4 for collection in the collection chamber 5. The water continues to flow downwards through the filter hood 2 and is finally discharged from the outlet 3 at the bottom of the separation chamber 1 to enter the next process.

[0033] It provides a basic treatment space and filtration structure for the separation of suspended solids in wastewater treatment, and realizes the initial separation of wastewater and suspended solids; the conical structure makes it difficult for particles to settle, and at the same time, when wastewater enters the separation chamber 1, it can flush the conical cover to flush the suspended solids into the separation port 4.

[0034] For a preferred implementation, please refer to Figure 2 and 4 It also includes a filter port 6, which is located on the inner wall of the separation chamber 1. The filter port 6 is located directly below the separation port 4 and is connected to the lower part of the inner cavity of the collection chamber 5. A filter screen is installed inside the filter port 6. The suspended solids and wastewater that enter the collection chamber 5 are returned to the separation chamber 1 through the filter port 6.

[0035] The suspended solids entering the collection chamber 5 will carry a certain amount of wastewater, which will accumulate in the collection chamber 5. Since the filter port 6 connects the lower part of the inner cavity of the collection chamber 5 and the separation chamber 1, and the filter port 6 is equipped with a filter screen, the wastewater can flow back into the separation chamber 1 through the filter screen, while the suspended solids are intercepted in the collection chamber 5 by the filter screen; thus, the suspended solids and the accompanying wastewater are effectively separated, reducing the waste of water resources, and at the same time preventing the wastewater from accumulating too much in the collection chamber 5 and affecting the normal use of the collection chamber 5.

[0036] For a preferred implementation, please refer to Figure 4-5 It also includes a door 7, which is set on the outer wall of the collection chamber 5. The outer wall of the collection chamber 5 has a notch, and the door 7, which can be opened and closed, is installed at the notch. When the door 7 is closed, it seals with the notch. When the door 7 is opened, the inside of the collection chamber 5 can be cleaned.

[0037] When the suspended solids in the collection chamber 5 accumulate to a certain level, the openable door 7 at the notch on the outer wall of the collection chamber 5 can be opened to clean the suspended solids in the collection chamber 5. After cleaning, the door 7 is closed, and the door 7 and the notch are sealed to prevent sewage leakage. This facilitates the cleaning of the suspended solids collected in the collection chamber 5 and ensures the normal operation of the equipment.

[0038] For a preferred implementation, please refer to Figure 2-3 It also includes a support ring 8 for supporting the filter cover 2, which is disposed on the inner wall of the separation chamber 1. When the filter cover 2 is placed in the separation chamber 1, the bottom edge abuts against the support ring 8.

[0039] When the filter cover 2 is placed in the separation chamber 1, the bottom edge of the filter cover 2 abuts against the support ring 8 on the inner wall of the separation chamber 1. The support ring 8 bears part of the weight of the filter cover 2, providing initial support for the filter cover 2; enhancing the stability of the filter cover 2, preventing the filter cover 2 from sinking or deforming due to its own weight or the impact of sewage, and ensuring the normal filtration function of the filter cover 2.

[0040] For a preferred implementation, please refer to Figure 2-3 It also includes a bracket 9, which is set inside the support ring 8. The bracket 9 has a conical design and is adapted to the inner wall of the filter cover 2. When the bracket 9 is placed in the separation chamber 1, the top outer wall of the bracket 9 abuts against the inner wall of the filter cover 2 to further improve the support capacity of the filter cover 2.

[0041] The bracket 9 is placed inside the support ring 8. It has a tapered design and is adapted to the inner wall of the filter cover 2. When the filter cover 2 is placed on the bracket 9, the top outer wall of the bracket 9 abuts against the inner wall of the filter cover 2, further distributing the pressure on the filter cover 2 and improving its support capacity. Together with the support ring 8, it provides more reliable support for the filter cover 2, enhances the impact resistance of the filter cover 2, and extends the service life of the filter cover 2.

[0042] For a preferred implementation, please refer to Figure 2-3 It also includes a fixing structure for fixing the filter cover 2, which is set on the top of the filter cover 2. The fixing structure includes a convex sleeve 10 with a fixing hole. The upper end of the bracket 9 is provided with a protruding post 11 with a through hole on the outer wall of the protruding post 11. When the filter cover 2 is placed on the bracket 9, the protruding post 11 is inserted into the convex sleeve 10 and the through hole and the fixing hole correspond to each other. Then it is locked by fixing screws, thereby avoiding the impact of sewage on the filter cover 2 and causing the filter cover 2 to shift.

[0043] When the filter cover 2 is placed on the bracket 9, the protruding post 11 is inserted into the protruding sleeve 10, and the through hole and the fixing hole correspond. The filter cover 2 is locked by passing through the through hole and the fixing hole, so that the filter cover 2 is firmly connected to the bracket 9. This prevents the filter cover 2 from being displaced due to the impact of sewage on the filter cover 2, and ensures that the position of the filter cover 2 in the separation chamber 1 is stable, thus ensuring the stability and reliability of the filtration effect.

[0044] For a preferred implementation, please refer to Figure 1-3 It also includes a diversion plate 12, which is disposed on the outer wall of the filter cover 2. Multiple sets of diversion plates 12 are equidistantly arranged around the outer wall of the filter cover 2. The filter screen on the filter cover 2 is disposed between adjacent diversion plates 12. The diversion plate 12 plays a strengthening role while diverting sewage to reduce impact force.

[0045] After the wastewater enters the separation chamber 1, the diversion plate 12 divides the wastewater, allowing it to contact the filter cover 2 more evenly and reducing the impact force of the wastewater on the filter cover 2. In addition, the diversion plate 12 also strengthens the structure of the filter cover 2, improves the filtration efficiency of the filter cover 2, reduces the local impact of wastewater on the filter cover 2, extends the service life of the filter cover 2, and enhances the overall strength of the filter cover 2.

[0046] For a preferred implementation, please refer to Figure 2 It also includes a threaded sleeve 13, which is located at the lower end of the outlet 3. The threaded sleeve 13 is threadedly installed inside the outlet 3. A second filter screen 14 is installed inside the threaded sleeve 13 for secondary filtration of sewage to improve the separation effect of suspended solids and sewage.

[0047] After initial filtration by filter hood 2, the wastewater flowing out of outlet 3 will pass through the second filter screen 14 for further filtration, intercepting suspended solids in the wastewater. This secondary filtration improves the separation effect between suspended solids and wastewater, making the wastewater discharged from separation chamber 1 cleaner and meeting higher wastewater treatment requirements. Meanwhile, the detachable design of the threaded sleeve 13 facilitates the replacement and maintenance of the second filter screen 14.

[0048] Among them, filter cover 2, filter screen and second filter screen are all made of stainless steel metal mesh. The pore size can be selected according to the size and distribution of suspended solids in the sewage. For example, if the main suspended solid particles in the sewage are large, a filter screen with a pore size of 1-2 mm can be selected; if the suspended solid particles are small, a filter screen with a pore size of 0.5-1 mm can be selected.

[0049] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
