Description

Technical Field

[0001] This utility model belongs to the field of sludge suction machine technology, specifically relating to a slag scraping mechanism for a center-driven sludge suction machine. Background Technology

[0002] In the field of wastewater treatment, the center-driven sludge suction machine is a key piece of equipment, undertaking the important task of collecting sludge from the bottom of the sedimentation tank, ensuring sedimentation effect, and maintaining the stable operation of the wastewater treatment system.

[0003] Existing wastewater contains a large number of complex components, including organic matter, inorganic matter, microorganisms, and various suspended solids. During the process of wastewater entering the central drive sludge suction machine, the agitation of the water flow and environmental changes cause light impurities such as grease, foam, and fibers to float to the surface, forming a scum layer on the surface of the inlet tank of the central drive sludge suction machine. Over time, if these scum are not removed in time, they will gradually accumulate and thicken. On the one hand, the scum will form scale in the inlet tank of the central drive sludge suction machine, forming a stubborn dirt layer that is not only difficult to clean but also affects the water flow pattern in the inlet tank. On the other hand, the scaled inlet tank will cause uneven water distribution, with some areas having excessively fast water flow and others having slow water flow or even stagnant water areas, which greatly reduces the overall treatment effect. Utility Model Content

[0004] The purpose of this invention is to provide a scraping mechanism for a center-driven sludge suction machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scraping mechanism for a center-driven sludge suction machine, comprising:

[0006] Mounting frame, with a vertical pole fixedly connected to one end of the top;

[0007] Slag scraper, which is connected to one end of the upright, is used to scrape off the floating slag in the water inlet tank of the central drive sludge suction machine;

[0008] The scraper is located at the bottom of the mounting frame and is used to scrape away the debris that has settled at the bottom of the center-driven sludge suction machine. The top of the scraper is connected to a scraper arm, which is connected to the mounting frame.

[0009] Preferably, the top of the scraper arm is provided with a connecting rod, and the two ends of the connecting rod are rotatably connected to the scraper arm and the mounting bracket respectively through rotating blocks.

[0010] Preferably, one end of the scraper arm is connected to a support rod, and the top of the support rod is connected to the mounting bracket.

[0011] Preferably, two sets of support plates are connected between the scraper and the scraper arm.

[0012] Preferably, the bottom of the upright is provided with a slag scraper.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The scum in the inlet tank of the central drive sludge suction machine can be removed in time by the scum scraper and scum scraper, which effectively prevents the scum from scaling in the inlet tank. This avoids the problem of water flow pattern change and uneven water distribution caused by scaling in the inlet tank, and ensures that the sewage can enter the sedimentation tank evenly, making the sedimentation process more stable and efficient, and improving the treatment effect of the entire sewage treatment system.

[0015] (2) The slag scraping mechanism can not only scrape off the scum in the water inlet tank, but the scraper at the bottom can also scrape the debris settled at the bottom of the central drive sludge suction machine at the same time, thus integrating the functions of scum cleaning and bottom debris cleaning, and improving work efficiency.

[0019] 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.

[0020] This utility model provides, for example Figure 1-2 The scraping mechanism of a center-driven sludge suction machine shown includes:

[0021] Mounting frame 1, with a vertical pole 2 fixedly connected to one of its top ends;

[0022] Slag scraper 3, which is connected to one end of the upright 2, is used to scrape off the floating slag in the water inlet tank of the central drive sludge suction machine;

[0023] Scraper 4 is located at the bottom of the mounting frame 1 and is used to scrape the debris settled at the bottom of the center-driven sludge suction machine. The top of the scraper 4 is connected to a scraper arm 5 and the scraper arm 5 is connected to the mounting frame 1.

[0024] The top of the scraper arm 5 is provided with a connecting rod 6, and the two ends of the connecting rod 6 are rotatably connected to the scraper arm 5 and the mounting bracket 1 through rotating blocks 7 respectively.

[0025] One end of the scraper arm 5 is connected to a support rod 8, and the top of the support rod 8 is connected to the mounting frame 1. The support rod 8 can provide additional support and strengthen the structural strength of the connection between the mounting frame 1 and the scraper arm 5.

[0026] Two sets of support plates 9 are connected between the scraper 4 and the scraper arm 5. The support plates 9 can strengthen the structural strength of the scraper 4 and the scraper arm 5, and can effectively disperse these external forces to prevent the scraper 4 and the scraper arm 5 from deforming due to uneven force during operation.

[0027] The bottom of the upright 2 is equipped with a slag scraper 10. When the upright 2 rotates, the rotating blades inside the slag scraper 10 will come into contact with the scum. The centrifugal force and friction generated by the rotation will break up the scum, making it easier for the slag scraper 3 to continuously scrape up the scum and push it to the designated position.

[0028] The scraping mechanism of the center-driven sludge suction machine has a mounting frame 1 connected to the top of the rotating cage at the center of the machine, and a scraper arm 5 connected to the bottom of the rotating cage. When the machine is running, the mounting frame 1 rotates slowly with the rotating cage, and the scraper 3 connected to one end of the upright 2 rotates accordingly. The scraper 3 contacts the scum in the water inlet tank. As the scraper 3 rotates with the mounting frame 1, its movement trajectory covers the surface of the water inlet tank. During the rotation, the scraper 3 continuously scrapes up the scum and pushes it to the designated position (the scum collection hopper inside the center-driven sludge suction machine). The scraper 10 at the bottom of the upright 2 will further collect or disperse the scum scraped by the scraper 3 during the rotation of the upright 2, making it easier to clean later and preventing the scum from accumulating and scaling in the water inlet tank, ensuring smooth water flow and uniform water distribution.

[0029] The scraper 4 at the bottom of the mounting frame 1 is connected to the scraper arm 5 and is further supported by the support rod 8. When the rotating cage and the mounting frame 1 rotate, the scraper arm 5 and the scraper 4 rotate synchronously. The scraper 4 contacts the bottom of the sedimentation tank. During the rotation, the scraper 4 continuously scrapes the debris (such as sludge, sand, etc.) settled at the bottom, causing it to move towards the sludge discharge port area inside the central drive sludge suction machine. The support plate 9 connects the scraper 4 and the scraper arm 5, enhancing the strength and stability of the scraper 4 and ensuring that the scraper 4 can withstand greater resistance when scraping debris, thus successfully completing the sludge scraping operation and achieving effective cleaning of the sediment at the bottom.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
