Description

Technical Field

[0001] The invention relates to the field of urban domestic sewage treatment and special equipment for sewage treatment, and in particular to an inverted double-U clamped submersible flow propeller. Background Art

[0002] Submersible flow thruster is a mechatronic submersible device whose impeller is driven by a motor reduction mechanism. It is widely used in the field of urban domestic sewage treatment, stirring sewage, mixing sludge, promoting the flow of water medium, and blocking sludge sedimentation. It is a key core equipment of sewage treatment plants. It consists of three parts: the main unit of the flow thruster, the underwater guide rail mounting seat, and the lifting device. The main unit of the equipment works at a position of about 6 meters underwater, so the underwater guide rail mounting seat is fixed on the bottom of the underwater pool, and the lifting device is installed on the surface of the pool. The main unit of the flow thruster is lifted by the above-water lifting device, lowered and slid along the guide rail, and works in place at the underwater pool bottom mounting seat. If it needs to be pulled up, it is directly lifted up by the lifting device and moved up along the guide rail. There are three major defects in traditional equipment technology: First, the underwater mounting seat structure is flat, and it is impossible to effectively fix and clamp the flowmaker placed on it. The flowmaker is prone to vibration and noise when running underwater. Second, the flowmaker is not naturally fixed and fastened in its working state, and it is impossible to form an effective underwater fixed supporting structure with the mounting seat. Third, there are many misunderstandings in traditional understanding. It is always believed that the high failure rate of flowmaker equipment is due to the poor quality of the flowmaker host. As a result, domestic manufacturers blindly improve the quality of the host, but ignore the overall systemic and integrated supporting requirements of the equipment, and even ignore the harshness, complexity and concealment of the equipment's underwater working conditions. They also fail to recognize that the inability to effectively fix and clamp the equipment underwater is the root cause of failure, vibration and short life.

[0003] To sum up, the equipment has strong systematization and high integration. More than half of the domestic market share is imported. There are always various problems with domestic equipment, which often have short service life, high failure rate and low user satisfaction. Therefore, on the basis of fully understanding the use conditions, understanding the mechanical principles and finding the root cause of the failure, an inverted double U clamping submersible flowmaker was invented. Through the inverted double U clamping device of the present invention, the gravity, the performance of the rubber parts and the relevance of the system structure are utilized to make the main body of the flowmaker tightly buckled on the mounting seat when it is in place, and it can also be loosened and disengaged when pulled up to ensure that the flowmaker can be automatically fixed and fastened underwater, and the technical problems of underwater relaxation, vibration and noise of the equipment are completely solved, and the market situation of high failure rate, short service life and user distrust of the flowmaker equipment is completely bid farewell. The invention has the practical significance of eliminating backwardness and replacing imports, and meets the user's yearning for high reliability, high quality and high standard products.

The inner wall of the tail cavity is in a moving pair state with the square guide rail 11. The longitudinal section of the tail cavity and the longitudinal section of the main flow generator 2 are the same central section that coincides with each other. The main flow generator 2 is lifted by a lifting device 3, and slides up and down along the square guide rail 11 through the tail cavity of the tail 9, so as to realize the functions of lowering the main equipment into place and moving it up and out. An inverted double U clamping device 4 is arranged at the lower part of the center of gravity of the main flow generator 2, which comprises two inverted double U clamping frames 6, and the inverted double U clamping frame 6 is provided. The fixing frame 6 is a concave form of two inverted U-shaped structures, which are symmetrically arranged longitudinally along the center line of the flow-making machine mainframe 2, and are connected to the tail cavity in a certain size structure. The tail cavity is used as a positioning reference, and it is also symmetrical with the longitudinal section of the tail cavity. The double U clamping device and the tail cavity are viewed from bottom to top, and the plan view is arranged in a herringbone structure. An inverted double U-shaped rubber pad is provided between the inverted double U clamping frame 6 and the inverted U-shaped support tenon block 7, and the inverted double U clamping frame 6 is connected and fixed to the inverted U-shaped support tenon block 7 by bolts. The inverted double U clamping device 4 and the two inverted double U-shaped tenons are placed under the flow-making machine mainframe 2.

The pulley 13 forms a rotating pair with the square guide rail 11, and the contact with the square guide rail 11 is linear, ensuring the chain connection between the flow-making device main unit 2 and the square guide rail 11, and ensuring that the movement will not be blocked.

The cylindrical section of the pulley shaft 12 and the inner hole of the pulley 13 are in a rotating pair state. A reasonable gap is left between the end face of the pulley 13 and the inner wall of the tail 9 and the pulley shaft stop flange 15 to ensure the realization of the rotating pair.
