[0035] In the above embodiment, the umbrella-shaped blocking component 14 comprises a conical plate 14-1 and an umbrella rod 14-2, the upper surface of the conical plate 14-1 constitutes the umbrella surface 14-1-1, the umbrella surface 14-1-1 is in the shape of a conical surface, or the umbrella surface 14-1-1 is in the same shape as the side surface of a circular truncated cone, so as to better buffer the sewage and avoid sludge accumulation on the umbrella surface 14-1-1. Figures 2-4 In the above embodiment, the umbrella-shaped blocking component 14 comprises a conical plate 14-1 and an umbrella rod 14-2, the upper surface of the conical plate 14-1 constitutes the umbrella surface 14-1-1, the umbrella surface 14-1-1 is in the shape of a conical surface, or the umbrella surface 14-1-1 is in the same shape as the side surface of a circular truncated cone, so as to better buffer the sewage and avoid sludge accumulation on the umbrella surface 14-1-1.

[0036] In the above embodiment, the umbrella-shaped blocking component 14 comprises a conical plate 14-1 and an umbrella rod 14-2, the upper surface of the conical plate 14-1 constitutes the umbrella surface 14-1-1, the umbrella surface 14-1-1 is in the shape of a conical surface, or the umbrella surface 14-1-1 is in the same shape as the side surface of a circular truncated cone, so as to better buffer the sewage and avoid sludge accumulation on the umbrella surface 14-1-1. Figure 4 In the above embodiment, the umbrella-shaped blocking component 14 comprises a conical plate 14-1 and an umbrella rod 14-2, the upper surface of the conical plate 14-1 constitutes the umbrella surface 14-1-1, the umbrella surface 14-1-1 is in the shape of a conical surface, or the umbrella surface 14-1-1 is in the same shape as the side surface of a circular truncated cone, so as to better buffer the sewage and avoid sludge accumulation on the umbrella surface 14-1-1. Figure 5 In the above embodiment, the umbrella-shaped blocking component 14 comprises a conical plate 14-1 and an umbrella rod 14-2, the upper surface of the conical plate 14-1 constitutes the umbrella surface 14-1-1, the umbrella surface 14-1-1 is in the shape of a conical surface, or the umbrella surface 14-1-1 is in the same shape as the side surface of a circular truncated cone, so as to better buffer the sewage and avoid sludge accumulation on the umbrella surface 14-1-1.

[0037] When the sludge-water separation equipment for sewage treatment is used, the driving mechanism drives the centrifugal filter cartridge 6 to rotate, sewage enters the centrifugal filter cartridge 6 from the feed inlet, under the action of gravity and water pressure, the sewage has a downward movement speed, in the process of the downward movement of the sewage, part of the sewage will impact on the umbrella surface 14-1-1, since the sewage cannot directly pass through the umbrella surface 14-1-1, the movement direction of the sewage must be changed to bypass the umbrella surface 14-1-1 from the side of the umbrella surface 14-1-1, in this way, the downward movement speed of the sewage is reduced, when the height difference between the feed inlet and the sludge outlet 11 is unchanged, the time of the sewage moving from the feed inlet to the sludge outlet 11 is lengthened, that is, the sludge-water separation time is lengthened, so that the sludge-water separation effect is improved.

[0038] At the same time, since the umbrella-shaped blocking part 14 is coaxial with the centrifugal filter cartridge 6 and the feed inlet, the sewage entering from the feed inlet will impact on the umbrella surface 14-1-1, and since the distance from the edge of the umbrella surface 14-1-1 to the inner wall surface of the centrifugal filter cartridge 6 is equal, the sewage will be equally dispersed into the gap between the umbrella surface 14-1-1 and the centrifugal filter cartridge 6, which is good in consistency and can ensure that all the sludge-water can be effectively separated.

[0039] In the process of the upward and downward movement of the sewage, under the action of the centrifugal force, the sewage will move to the edge of the centrifugal filter cartridge 6, wherein the water in the sewage flows out of the centrifugal filter cartridge 6 into the water buffer cavity 7, and then is discharged through the water discharge channel, the sludge in the sewage is blocked by the centrifugal filter cartridge 6 and leaves the centrifugal filter cartridge 6 through the sludge outlet 11, so as to realize sludge-water separation; at the same time, since the umbrella rod 14-2 rotates with the centrifugal filter cartridge 6, the umbrella rod 14-2 and the umbrella surface 14-1-1 can also exert a force on the sewage to make the sewage move outward, which is beneficial to improve the sludge-water separation effect.

[0040] It should be noted that when the sludge-water separation equipment for sewage treatment is used, the sewage will fill the entire centrifugal filter cartridge 6.

[0041] As a preferred specific embodiment, as shown in Figures 2-4 The centrifugal filter cartridge 6 includes a cylinder body with filter holes and a sealing plate connected to the lower end of the cylinder body, the sludge outlet 11 is arranged on the sealing plate, and the umbrella rod 14-2 is directly or indirectly fixedly connected with the sealing plate, so that the structure is simple. The shell 1 is connected with the feed joint 2, and the lower end opening of the feed joint 2 constitutes the feed inlet.

[0042] In other specific embodiments, the umbrella rod 14-2 can also be fixedly connected with the inner side wall of the cylinder body of the centrifugal filter cartridge 6 through a connecting rod. In one specific embodiment, the centrifugal filter cartridge 6 and the umbrella-shaped blocking part 14 are made of stainless steel, and the centrifugal filter cartridge 6 and the umbrella-shaped blocking part 14 can be fixedly connected by welding or the like.

[0043] As a preferred specific embodiment, as shown in Figure 4 The shell 1 and the centrifugal filter cartridge 6 form a sludge buffer cavity 13 at the lower part of the centrifugal filter cartridge 6, the sludge discharge port 11 is located at the edge of the sealing plate and communicates with the sludge buffer cavity 13, and the sludge buffer cavity 13 is provided with a sludge discharge channel (specifically, the internal channel of the sludge discharge joint 4, which is used to connect an external pipeline) for discharging sludge outward. At this time, when the sludge discharge port 11 rotates around the axis of the centrifugal cylinder, the position of the sludge discharge channel remains unchanged, which facilitates sludge discharge and the use of the sludge discharge channel to transport sludge to a remote place.

[0044] In other specific embodiments, a vertically extending sludge discharge pipe can be directly connected at the sludge discharge port 11, and the shell 1 has an annular (or circular) avoiding hole for avoiding the rotating route of the sludge discharge pipe. When in use, the sludge water separation equipment for sewage treatment is arranged above the sludge tank, and the sludge directly falls into the sludge tank from the sludge discharge pipe, and the sludge in the sludge tank can be transported to a remote place by using a screw conveyor or other equipment.

[0045] In the above specific embodiment, the sealing plate is a flat plate, and the umbrella rod 14-2 is directly fixedly connected with the upper plate surface of the sealing plate by welding or other methods, so as to realize the direct fixed connection of the umbrella rod 14-2 with the centrifugal filter cartridge 6.

[0046] The sludge enters the sludge buffer cavity 13 and the sludge discharge channel in turn under the action of water pressure and gravity, and since the feed inlet continuously enters new sewage, the sludge will move along the sludge discharge channel to a remote place under the action of water pressure.

[0047] In order to facilitate the sludge to enter the sludge buffer cavity 13, as a preferred specific embodiment, the upper plate surface of the sealing plate is further fixedly connected with a circular truncated cone-shaped sludge guide seat 12, the diameter of the upper bottom of the circular truncated cone-shaped sludge guide seat 12 is smaller than that of the lower bottom, the edge of the circular truncated cone-shaped sludge guide seat 12 is provided with a sludge discharge through hole corresponding to the sludge discharge port 11, the side surface of the circular truncated cone-shaped sludge guide seat 12 constitutes a guide surface for guiding the sludge to enter the sludge discharge through hole, and the umbrella rod 14-2 is connected with the upper bottom of the circular truncated cone-shaped sludge guide seat 12, so as to realize the indirect fixed connection of the umbrella rod 14-2 with the sealing plate.

[0048] In actual use, under the guidance of the guide surface, the sludge will better enter the sludge discharge through hole along the guide surface under the combined action of gravity and water pressure, so as to avoid the accumulation of sludge at the middle position of the lower part of the centrifugal filter cartridge 6 and facilitate the sludge to enter the sludge buffer cavity 13.

[0049] At the same time, since the centrifugal filter cartridge 6 is rotating at all times, the position of the sludge discharge through hole is changing at all times, so as to better enable the sludge circumferentially distributed in the centrifugal filter cartridge 6 to enter the sludge discharge through hole.

[0050] The circular truncated cone-shaped sludge guide seat 12 can be integrally formed with the umbrella rod 14-2 or fixedly connected with the umbrella rod 14-2 by welding or other methods.

[0051] In the above specific implementation, the number of mud discharge holes is one, resulting in poor mud discharge effect.

[0052] To solve the above problems, preferably, at least two mud discharge holes are evenly distributed along the same circumference, and each mud discharge hole corresponds to a mud discharge port 11.

[0053] In different specific embodiments, the number of mud discharge holes can be two, three, four or more. Figure 4 Specifically, there are two sludge discharge holes. The more sludge discharge holes there are, the smaller the central angle corresponding to the line connecting adjacent sludge discharge holes, which is more conducive to the sludge distributed circumferentially inside the centrifugal filter cartridge 6 entering the sludge discharge holes.

[0054] It should be noted that the total flow area of ​​the sludge discharge through hole (sludge discharge port 11) should not be too large, so as to avoid a large amount of water directly entering the sludge buffer chamber 13. Those skilled in the art can design the total flow area according to actual needs, which will not be elaborated here.

[0055] In the above specific embodiment, the sludge may accumulate in the middle of the sludge buffer chamber 13 after entering the sludge buffer chamber 13.

[0056] To address the aforementioned problems, as a preferred embodiment, such as... Figure 3 As shown, a scraper 9 is provided inside the sludge buffer chamber 13. The scraper 9 is equipped with a rotary power source for driving the scraper 9 to rotate. The rotation axis of the scraper 9 coincides with the rotation axis of the centrifugal filter cartridge 6. The scraper 9 can scrape the sludge in the sludge buffer chamber 13 to the inlet of the sludge discharge channel, so that the sludge in the sludge buffer chamber 13 can be discharged through the sludge discharge channel.

[0057] Preferably, the driving mechanism includes a rotary power source for driving the centrifugal filter cartridge 6 to rotate. The rotary power source for driving the centrifugal filter cartridge 6 to rotate and the rotary power source for driving the scraper 9 to rotate are the same rotary power source (rotary motor 8 or rotary cylinder, etc.). The rotary power source is connected to a drive shaft 10. The axis of the drive shaft 10 coincides with the rotation axis of the centrifugal filter cartridge 6. The upper end of the drive shaft 10 is fixedly connected to the sealing plate. The scraper 9 is connected to the drive shaft 10 to drive the centrifugal filter cartridge 6 and the scraper 9 to rotate synchronously. The structure is simple.

[0058] In other specific embodiments, referring to the Chinese utility model patent with authorization announcement number CN222647827U, the first rotary power source drives the centrifugal filter cartridge 6 to rotate through a gear mechanism, and the scraper 9 can be driven by the second rotary power source. The output shaft of the second rotary power source is connected to the scraper 9 through key connection or interference fit, etc., and does not contact the centrifugal filter cartridge 6.

[0059] In other specific embodiments, refer to Figures 2-4 As shown, the sludge buffer chamber 13 can be configured as a funnel shape, and the sludge discharge connector 4 is installed at the outlet of the sludge buffer chamber 13. By utilizing the characteristics of the funnel, all the sludge in the sludge buffer chamber 13 can be discharged through the sludge discharge channel.

[0060] As a preferred embodiment, such as Figures 2-4 As shown, both the upper and lower parts of the cylinder are rotatably sealed to the cylinder via sliding pairs. The sliding pairs include a slip ring 6-2 and an annular groove 1-1. The slip ring 6-2 is disposed on one of the shell 1 and the cylinder, and the annular groove 1-1 is disposed on the other. The sliding pairs at the upper and lower parts of the cylinder, the cylinder itself, and the shell 1 together form the water buffer chamber 7. The sliding pairs at the lower part of the cylinder, the cylinder itself, the shell 1, and the sealing plate together form the sludge buffer chamber 13. Specifically, the cylinder includes a main body with filter holes and connecting rings 6-1 located at both ends of the main body. The connecting rings 6-1 are provided with corresponding slip rings 6-2 or annular grooves 1-1.

[0061] At this point, in addition to serving to straighten and support the centrifugal filter cartridge 6, the sliding pair also serves to separate the water buffer chamber 7 and the sludge buffer chamber 13, resulting in a simple structure.

[0062] In other specific embodiments, refer to Figure 5 The Chinese utility model patent with authorization announcement number CN222647827U states that the housing 1 includes a support, on which a rotating groove is provided. The centrifugal filter cartridge 6 is rotatably connected to the rotating groove to limit the position of the centrifugal filter cartridge 6 and to separate the water buffer chamber 7 and the sludge buffer chamber 13.

[0063] To facilitate the movement of the sludge-water separation equipment for sewage treatment, the housing 1 also includes support legs 5, with universal wheels with brakes bolted to the bottom of the support legs 5.

[0064] Of course, when the sludge-water separation equipment for sewage treatment is large (for example, when the height of the centrifugal filter cartridge 6 is greater than 2 m and the diameter is greater than 1 m), the sludge-water separation equipment for sewage treatment needs to be fixedly installed on the ground.

[0065] Specific embodiment 2 of the sludge-water separation equipment for sewage treatment provided by this utility model:

[0066] In reference Figures 1-4 On the basis of, such as Figure 5 As shown, the main difference between specific embodiment 2 and specific embodiment 1 is that in specific embodiment 1, the umbrella rod 14-2 is fixedly connected to the centrifugal filter cartridge 6, while in specific embodiment 2, the umbrella rod 14-2 is fixedly connected to the shell 1.

[0067] Specifically, such as Figure 5As shown, the umbrella rod 14-2 penetrates the mud discharge port 11 and is fixedly connected with the shell 1, at this time, only the centrifugal filter cartridge 6 rotates, and the umbrella-shaped blocking structure does not rotate.

[0068] Finally, it should be noted that the above is only the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified without paying creative labor for the technical solutions recorded in the foregoing embodiments, or part of the technical features are replaced, or different embodiments are organically combined, so as to combine the specific embodiments given in the drawings, of course, those skilled in the art can also combine the specific embodiments not given in the remaining drawings of the specification. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
