Description

Technical Field

[0001] The present utility model relates to the field of sewage treatment, and specifically relates to an interception device for sewage treatment. Background Technique

[0002] In the process of sewage treatment, the interception device plays a crucial role. Its main function is to remove pollutants such as solid particles, suspended substances, and grease in the sewage. If these garbage enter the sewage treatment equipment directly without treatment, it will not only affect the treatment effect but also may damage the equipment. However, the current interception device for sewage treatment (authorized announcement number CN219964096U) avoids the situation of manual cleaning and potential safety hazards, but it has a complex structure, and it is relatively troublesome to replace the filter screen once it is damaged. Content of the Utility Model

[0003] In order to overcome the above deficiencies, the present utility model provides an interception device for sewage treatment.

[0004] The technical solution adopted by the present utility model:

[0005] An interception device for sewage treatment includes a base. At the rear sides of the left and right ends of the top of the base, columns are vertically and fixedly connected. A rotating shaft is rotatably connected between the tops of the two columns. The right end of the rotating shaft penetrates through the column and is fixedly connected with a turntable. Three outer frames are fixedly connected to the outer wall of the rotating shaft, and the three outer frames are radially distributed at equal angles. The right side of the outer frame is open. The inner top wall and inner bottom wall of the outer frame are both provided with sliding grooves, and the sliding grooves penetrate through the outer frame to the right. An activity frame is arranged inside the outer frame. The activity frame is located in the sliding groove and is slidably matched with the sliding groove. A filter screen is fixedly connected between the inner side walls of the activity frame. The right end of the rear side wall of the activity frame is fixedly connected with a handle. A fixing groove is arranged at the middle position of the top of the base. A retaining strip is arranged in the fixing groove and is slidably matched with the fixing groove. The top of the front side wall of the retaining strip is arc-shaped, and the arc surface of the retaining strip is exposed from the fixing groove. Three guide rods are fixedly connected to the bottom of the retaining strip. The guide rods are slidably inserted into the base. A spring is sleeved on the outer wall of the guide rod. The top and bottom of the spring are respectively fixedly connected with the bottom of the retaining strip and the inner bottom wall of the fixing groove.

[0006] The beneficial effects of the present utility model:

[0007] The structure of the present utility model is simple, and it is convenient to replace the filter screen once it is damaged. The design of alternating use of the three filter screens allows for quick replacement when replacing the filter screen. By controlling the rotation of the filter screen through the turntable, the operation is simple and fast. The filter screen can be directly pulled out and inserted into the outer frame, improving the efficiency of filter screen replacement. The arc surface design and reset locking function of the retaining strip ensure the stability and safety of the filter screen during the replacement process. Description of the Drawings

Specific embodiments

[0013] As Figures 1-4 Shown: An interception device for sewage treatment includes a base 1. At the rear sides of the left and right ends of the top of the base 1, support pillars 2 are vertically and fixedly connected. Between the tops of the two support pillars 2, a rotating shaft 3 is rotatably connected. The right end of the rotating shaft 3 penetrates through the support pillar 2 and is fixedly connected with a turntable 4. Three outer frames 5 are fixedly connected to the outer wall of the rotating shaft 3. The three outer frames 5 are radially distributed at equal angles. The right side of the outer frame 5 is open. The inner top wall and inner bottom wall of the outer frame 5 are both provided with sliding grooves 6. The sliding grooves 6 penetrate through the outer frame 5 to the right. Inside the outer frame 5, there is a movable frame 7. The movable frame 7 is located in the sliding groove 6 and is slidably matched with the sliding groove 6. A filter screen 8 is fixedly connected between the inner side walls of the movable frame 7. The right end of the rear side wall of the movable frame 7 is fixedly connected with a handle 9. At the middle position of the top of the base 1, a fixing groove 10 is provided. Inside the fixing groove 10, there is a retaining bar 11. The retaining bar 11 is slidably matched with the fixing groove 10. The top of the front side wall of the retaining bar 11 is arc-shaped. The arc surface of the retaining bar 11 exposes the fixing groove 10. Three guide rods 12 are fixedly connected to the bottom of the retaining bar 11. The guide rods 12 are slidably inserted into the base 1. A spring 13 is sleeved on the outer wall of the guide rod 12. The top and bottom ends of the spring 13 are respectively fixedly connected with the bottom of the retaining bar 11 and the inner bottom wall of the fixing groove 10.

[0014] When in the working state, the three filter screens 8 are located at different positions respectively. One of the filter screens 8 is located at the bottom, directly facing the sewage inlet, and the other two filter screens 8 are respectively located on both sides, radially distributed. Under the elastic force of the spring 13, the arc surface of the retaining bar 11 exposes the fixing groove 10 to limit the movement of the outer frame 5;

[0015] As the filtration progresses, the filter screen 8 at the bottom will gradually be blocked by dirt and needs to be cleaned or replaced. At this time, by rotating the turntable 4, the rotating shaft 3 is driven to rotate backward, so that the three outer frames 5 and the filter screens 8 thereon rotate together;

[0016] When the filter screen 8 that needs to be cleaned or replaced (i.e., the lowermost filter screen 8) rotates to the upper side, the front outer frame 5 will first pass through the position between the two struts 2 and continue to rotate to the rear side of the two struts 2, so that the new filter screen 8 rotates to the sewage inlet and continues the filtering work. During this process, due to the arc-shaped surface design of the stop strip 11, the outer frame 5 can smoothly slide along its arc-shaped surface. At the same time, the stop strip 11 moves downward along the fixed groove 10 under the inclined pressure. After the outer frame 5 completely slides past the stop strip 11, the stop strip 11 resets under the elastic force of the spring 13 and exposes the fixed groove 10 again. At this time, the filter screen 8 is impacted by the sewage at the rear side, which will drive the outer frame 5 to abut against the rear side wall of the stop strip 11, forming a locked state and restricting the forward rotation of the outer frame 5;

[0017] Under the locking action of the stop strip 11, at this time, the three outer frames 5 are in a static state. The user can grasp the handle 9 and pull out the filter screen 8 and the movable frame 7 that need to be replaced along the sliding groove 6 for cleaning or replacement. Then, insert the cleaned filter screen 8 back into the corresponding outer frame 5 along the sliding groove 6 and wait for the next cleaning or replacement. The design of alternating use of the three filter screens 8 can timely block the sewage inlet when replacing the filter screen 8 and ensure the continuity of the filtering work.
