Description

Technical Field

[0001] The utility model belongs to the field of sewage treatment, and in particular relates to a small space scraper rake with a counterweight block. Background Art

[0002] A scraper is a commonly used device in sewage and sludge treatment. Sewage enters the pool through a water distribution pipe pre-buried at the bottom of the annular water inlet trough around the pool. After passing through the water retaining skirt, it continuously flows to the center of the sedimentation tank. In this process, floating objects and sediment are separated from the water. The main function of the scraper rake structure is to scrape floating objects on the water surface into the slag hopper and discharge them out of the pool through the slag discharge pipe connected to the slag hopper. Currently, the commonly used scraper uses a drive device and a transmission device to drive the skimmer plate and scraper rake forward, thereby moving the suspended matter in a specified direction. The scraper rake of the scraper does not have the space restriction above the liquid level and is larger in size. However, in environments where the scraper rake space is limited, the original scraper rake is not suitable.

[0003] Therefore, it is necessary to provide a scraper rake that is suitable for small spaces. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a small space scraper rake with a counterweight block, which is used to solve the problem that the current scraper rake of the mud scraper is large in size, resulting in limited application environment.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A small space scraper rake with a counterweight block includes a counterweight block, a silicone scraper and a connecting rod. The counterweight block and the silicone scraper are respectively connected to the connecting rod through a support plate and a fixed plate. By controlling the mass of the counterweight block, the connecting rod swings with the water flow, thereby driving the silicone scraper to scrape away floating objects.

[0007] Furthermore, the support plate is fixedly connected to the lower end of the connecting rod.

[0008] Furthermore, the upper portion of the fixing plate is fixedly connected to the lower end of the connecting rod, and the lower end is connected to one side of the silicone scraper.

[0009] Furthermore, the other side of the silicone scraper is connected to the pressure plate by bolts.

[0010] Furthermore, the upper end of the connecting rod is fixedly connected to the lower end of the sleeve.

[0011] Furthermore, the shaft sleeve is sleeved on the outer surface of the rotating shaft.

[0012] Furthermore, the upper portion of the rotating shaft is fixedly connected to the bracket.

[0013] Furthermore, a baffle is fixed to the lower end of the bracket.

[0014] Beneficial effects of the utility model:

[0015] (1) The utility model adjusts the weight of the counterweight block so that the connecting rod maintains balance when swinging with the water flow, thereby driving the silicone scraper to scrape away floating objects on the water surface. It can also be used in small space environments, increasing the application scenarios.

[0016] (2) The utility model does not require a driving mechanism. The device can obtain power only through the power of the water flow, thereby moving, scraping off floating objects on the water surface, and separating floating objects and sediments from the water.

[0017] (3) The utility model has a simple structure and is easy to operate, thus reducing production costs and use costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely examples. The present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] like Figures 1 to 3As shown, the utility model provides a small space scraper with a counterweight, including a counterweight 11, a silicone scraper 1, and a connecting rod 4. The counterweight 11 and the silicone scraper 1 are respectively connected to the connecting rod 4 via a support plate 3 and a fixed plate 2. By controlling the mass of the counterweight 11, the connecting rod 4 swings with the water flow, thereby driving the silicone scraper 1 to scrape away floating debris. The upper end of the connecting rod 4 is fixedly connected to the shaft sleeve 5, which is sleeved on the outer surface of the rotating shaft 6. The upper end of the rotating shaft 6 is fixedly connected to the bracket 9. The right side of the lower end of the fixed plate 2 is connected to the left side of the upper end of the silicone scraper 1. The right side of the upper end of the silicone scraper 1 is connected to the pressure plate 8. A bolt 7 passes through the silicone scraper 1 and the fixed plate 2 from the right side of the pressure plate 8 to fix the silicone scraper 1. A baffle 10 is fixed to the lower end of the bracket 9 near one end of the connecting rod 4 to limit the position of the connecting rod 4.

[0025] When water flows into the water distribution pipe at the bottom of the sink, the flow of water drives the silicone scraper 1 to move, thereby driving the connecting rod 4 to swing back and forth, supporting the silicone scraper 1, and thus scraping off floating objects on the water surface. The counterweight 11 provided on the connecting rod 4 balances the connecting rod 4, allowing the silicone scraper 1 to successfully scrape off floating objects and separate them from the sediment in the water. The upper end of the rotating shaft 6 is fixedly connected to the bracket 9, so that the position of the rotating shaft 6 is fixed, so that the sleeve 5 sleeved on the outer surface of the rotating shaft 6 rotates along the rotating shaft 6, causing the connecting rod 4 fixedly connected to the sleeve 5 to reciprocate with the connection point as the fixed point. When the connecting rod 4 moves, it will be limited by the baffle 10 at the lower end of the bracket 9, so that the silicone scraper 1 can scrape off floating objects in the water distribution pipe.

[0026] like Figure 1 and 3 As shown, the support plate 3 is "L"-shaped, and its side surface is fixedly connected to the left side of the lower end of the connecting rod 4. A counterweight 11 is placed on the support plate 3 to maintain the balance of the connecting rod 4.

[0027] The counterweight 11 is placed on the support plate 3 on the left side of the lower end of the connecting rod 4. The weight of the counterweight 11 is adjusted according to the size of the water flow to maintain the balance of the connecting rod 4 and allow the silicone scraper 1 to scrape off floating objects on the water surface.

[0028] The upper left end of the fixed plate 2 is fixedly connected to the right side of the lower end of the connecting rod 4, and the lower end is connected to the upper left end of the silicone scraper 1, so that the connecting rod 4 is connected to the silicone scraper 1. When the connecting rod 4 swings with the water flow, it drives the silicone scraper 1 to move, thereby scraping off floating objects on the water surface.

[0029] The upper right end of the silicone scraper 1 is connected to the pressure plate 8 by a bolt 7, so that the silicone scraper 1 is fixed to the right side of the fixed plate 2. When the connecting rod 4 drives the fixed plate 2 to move, it indirectly drives the silicone scraper 1 to move, so that the silicone scraper 1 scrapes off floating objects.

[0030] The pressing plate 8 is arranged on the right side of the upper end of the silicone scraper 1, so that the silicone scraper 1 is fitted with the fixing plate 2, and then the silicone scraper 1 is fixed to the lower end of the fixing plate 2 by the bolt 7.

[0031] like Figure 1 and 2 As shown, the upper end of the connecting rod 4 is fixedly connected to the lower end of the sleeve 5. Under the impact of the water flow, the connecting rod 4 is powered, and the connecting rod 4 is fixed to the lower end of the sleeve 5. With the rotating shaft 6 as the support point, it moves freely with the water flow, scraping the floating objects into the slag bucket.

[0032] The shaft sleeve 5 is sleeved on the outer surface of the rotating shaft 6 . When the connecting rod 4 is subjected to the dynamic motion of the water flow, the shaft sleeve 5 rotates on the surface of the rotating shaft 6 to support the connecting rod 4 .

[0033] The upper part of the rotating shaft 6 is fixedly connected to the bracket 9. In a small space application scenario, the bracket 9 is used to fix the rotating shaft 6, and then the connecting rod 4 drives the silicone scraper 1 to move with the rotating shaft 6 as the support point to scrape off floating objects.

[0034] A baffle 10 is fixed to the lower end of the bracket 9, and the baffle 10 is inclined toward the connecting rod 4. When the connecting rod 4 moves with the water flow, it prevents the connecting rod 4 from moving too much, resulting in unstable movement.

[0035] The method of using the present utility model is as follows: When water flows into the water distribution pipe at the bottom of the sink, the flow of water is used to drive the silicone scraper 1 to move, thereby driving the connecting rod 4 to swing back and forth, supporting the silicone scraper 1, and thus scraping off floating objects on the water surface. The counterweight 11 provided on the connecting rod 4 balances the connecting rod 4, so that the silicone scraper 1 can successfully scrape off floating objects and separate them from the sediment from the water. The upper end of the rotating shaft 6 is fixedly connected to the bracket 9, so that the position of the rotating shaft 6 is fixed, so that the sleeve 5 sleeved on the outer surface of the rotating shaft 6 rotates along the rotating shaft 6, so that the connecting rod 4 fixedly connected to the sleeve 5 reciprocates with the connection point as the fixed point. When the connecting rod 4 moves, it will be limited by the baffle 10 at the lower end of the bracket 9, so that the silicone scraper 1 can scrape off floating objects in the water distribution pipe.
