Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation tanks, and particularly relates to a detection device for detecting the chain synchronism of a non-metallic chain sludge scraper. Background Art

[0002] The scraper of the sludge scraper used in the sedimentation tank is driven by a chain. During the operation of the chain, there is relative movement between the chain and the sprocket and other chain components. After long-term use, the chain is prone to wear, resulting in chain slack, elongation, and even breakage. In order to ensure the normal operation of the scraper, the utility model designs a detection device for detecting the chain synchronism of a non-metallic chain sludge scraper. Content of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the purpose of the utility model is to provide a detection device for detecting the chain synchronism of a non-metallic chain sludge scraper, with reasonable structural design, which can effectively monitor the chain synchronism, ensure the normal operation of the sludge scraper, and has strong practicability.

[0004] In order to achieve the above purpose, the utility model is realized through the following technical solutions: A detection device for detecting the chain synchronism of a non-metallic chain sludge scraper includes a proximity sensing device arranged on the inner wall of the sedimentation tank. The proximity sensing device includes a fixing frame, a signal detection device, and a metal plate. The fixing frame is fixed on the opposite side walls of both sides of the sedimentation tank. A signal detection device is arranged above the fixing frame. A metal plate is rotatably hung inside the fixing frame. The metal plate is in contact and cooperation with the scraper, and the transmission chain is below the scraper.

[0005] Preferably, the inner end edge of the fixing frame is set higher than the scraper for the scraper to pass through conveniently.

[0006] Preferably, the metal plate is hung on the fixing frame through a pin shaft.

[0007] The beneficial effects of the utility model: The structure of the utility model is designed reasonably. A proximity sensing device is respectively arranged on both sides of the sedimentation tank wall to detect whether the chains of the non-metallic chain sludge scraper are synchronous. If it is detected that they are not synchronous, an alarm signal is sent and the machine is stopped at the same time, avoiding affecting the sludge scraping and slag scraping effects, causing damage to the chains of the non-metallic chain sludge scraper, and malfunctions of the overall device. The use effect is good, and the sludge scraping efficiency is greatly improved. Description of the Drawings

[0008] The following will describe the utility model in detail in conjunction with the drawings and specific embodiments;

[0009] Figure 1 is the structural schematic diagram of the utility model;

[0010] Figure 2 ForFigure 1 Schematic enlarged view of part B. Specific embodiments

[0011] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0012] Referring to Figure 1-2 , the following technical solution is adopted in this specific embodiment: A detection device for detecting the chain synchronism of a non-metallic chain sludge scraper includes a proximity sensing device arranged on the inner wall of sedimentation tank A. The proximity sensing device includes a fixing frame 1, a signal detection device 2 and a metal plate 3. The fixing frame 1 is fixed on the corresponding side walls on both sides of the sedimentation tank. A signal detection device 2 is arranged above the fixing frame 1. A metal plate 3 is rotatably suspended inside the fixing frame 1. The metal plate 3 is in contact and cooperation with a scraper 4, and a driving chain 5 is below the scraper 4.

[0013] It should be noted that the inner edge of the fixing frame 1 is higher than the scraper 4, which is convenient for the scraper to pass through.

[0014] In addition, the metal plate 3 is suspended on the fixing frame 1 through a pin shaft.

[0015] The working principle of this specific embodiment: When there is no scraper passing by, the metal plate is in a vertically hanging state that can detect signals. When the scraper passes by, it drives the metal plate and the signal cannot be detected. By comparing the signal difference time on both sides, it is possible to monitor whether the chains of the non-metallic chain sludge scraper are synchronized, and to protect the normal operation of the overall device.

[0016] In this specific embodiment, a proximity sensing device is respectively arranged on both sides of the sedimentation tank wall to detect whether the chains of the non-metallic chain sludge scraper are synchronized. If non-synchronization is detected, an alarm signal will be sent and the machine will be stopped at the same time, so as to avoid affecting the sludge scraping and slag scraping effects, causing damage to the chains of the non-metallic chain sludge scraper, and malfunction of the overall device. The use effect is good, and the sludge scraping efficiency is greatly improved.

[0017] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
