Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a chain plate type scraper drive chain tension regulating device. Background Art

[0002] Chain scraper is a relatively common and mature product in the field of sewage treatment. It uses the movement of the scraper to collect the sludge into the designated mud bucket or mud discharge chute. Therefore, chain scraper is widely used in rectangular sedimentation tanks.

[0003] The power unit of a chain scraper is typically installed on top of the tank, using a chain drive to drive the scraper. In some rectangular tanks, such as double-layer tanks and inclined plate sedimentation tanks, the top platform where the chain scraper's power unit is installed is located a considerable distance from the scraper, typically exceeding 3 meters (compared to approximately 1.5 meters for traditional rectangular tanks). The drive chain required for transmission is therefore very long. During installation, the chain's tightness must be maintained within an appropriate range to prevent excessive resistance due to overtightening or falling off due to overloosening.

[0004] The traditional pool top tensioner has limited ability to adjust the chain tension, and a new type of chain tensioner is needed to tighten the longer drive chain. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model provides a chain plate type scraper drive chain tensioning device, comprising:

[0006] Drive chain tensioners, two of which are placed on both sides of the drive chain and in contact with the drive chain;

[0007] The tightening strip is used to adjust the position of the drive chain tensioner. The tightening strip is installed on both sides of the drive chain tensioner. Two rows of fixing holes are opened on the tightening strip at equal intervals. The fixing holes are used to install the drive chain tensioner in different hole positions to adjust the distance between the two drive chain tensioners.

[0008] The fixing assembly is used to connect and fix the drive chain tensioner and the tightening strip. The fixing assembly includes bolts and nuts, which are assembled on the fixing holes.

[0009] As a preferred solution of the present invention, a drive chain guide plate is provided on the inner side surface of the drive chain tensioner. The drive chain guide plate is an arc-shaped surface for reducing friction between the drive chain and the plate when the drive chain rotates.

[0010] As a preferred solution of the present invention, the fixing assembly further includes a stainless steel clamp and a gasket, and the stainless steel clamp and the gasket are arranged between the bolt and the nut.

[0011] As a preferred solution of the present invention, the stainless steel clamp is in a U-shape and is buckled onto the tightening strip.

[0012] As a preferred solution of the present invention, the tightening strip is sixteen inches long.

[0013] As a preferred solution of the present invention, the drive chain tensioner and the tightening strip are made of nylon.

[0014] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0015] This new chain scraper drive chain tensioner, featuring a drive chain tensioner, take-up bar, and mounting assembly, effectively adjusts the tension of the chain scraper drive chain. This device not only improves the installation precision and stability of the drive chain but also addresses the limited adjustment capabilities of traditional tank top tensioners. It is particularly suitable for applications requiring long-distance transmission, such as rectangular sedimentation tanks, double-layer tanks, and inclined plate sedimentation tanks. Furthermore, the use of nylon for the drive chain tensioner and take-up bar enhances the device's wear and corrosion resistance, extending its service life and reducing maintenance costs.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1

[0022] like Figures 1 to 3As shown, a specific embodiment of the chain scraper drive chain tensioning device described in the present invention includes: two drive chain tensioners 1, respectively placed on either side of the drive chain and in contact with the drive chain; a tensioning bar 2 mounted on either side of the drive chain tensioner 1, with two rows of equally spaced fixing holes formed on the tensioning bar 2 for adjusting the spacing between the drive chain tensioners 1 on either side; and a fixing assembly 3 comprising bolts and nuts, a stainless steel clamp, and a gasket for connecting and fixing the drive chain tensioner 1 and the tensioning bar 2. In actual application, the appropriate fixing hole position is selected based on the installation position of the chain scraper and the length of the drive chain. By adjusting the position of the fixing holes on the tensioning bar 2, the tightness of the drive chain can be precisely adjusted.

[0023] The inner side of the drive chain tensioner 1 is provided with a drive chain guide plate, which is an arc-shaped surface used to reduce the friction between the drive chain and the plate when the drive chain rotates; the tightening strip 2 is sixteen inches long, and the drive chain tensioner 1 and the tightening strip 2 are made of nylon.

[0024] The working principle of the present utility model is as follows: when the chain scraper needs to adjust the tightness of the drive chain, first loosen the bolts and nuts in the fixing assembly 3 to loosen the connection between the drive chain tensioner 1 and the tightening strip 2. Then, according to actual needs, move the position of the drive chain tensioner 1 on the tightening strip 2 and select a suitable fixing hole position for fixing. Finally, tighten the bolts and nuts to make the stainless steel clamp and gasket fit tightly on the tightening strip 2, thereby firmly fixing the drive chain tensioner 1 on the tightening strip 2.

[0025] The components in this article are all universal standard parts or components known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

[0026] Although the specific embodiments of the present invention are described in detail above, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by ordinary technicians in this field, various changes can be made without departing from the purpose of the present invention. Modifications or deformations that do not involve creative work are still within the scope of protection of the present invention.
