Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ultrasonic waves, in particular to ultrasonic defoaming equipment. Background Art
[0002] Existing defoaming technology is applied to the fast-moving consumer goods (food) industry. Based on ultrasonic vibration, the curved surface design of the defoaming tool head cavity surface is used to push air and generate impact airflow to eliminate filling bubbles that appear during food production, so as to facilitate the next process production or filling.
[0003] At present, mechanical defoaming is more effective, but it needs to contact with the foam, so there are some defects; for example, non-contact ultrasonic equipment defoaming has poor equipment stability, especially in pursuit of defoaming efficiency. If high efficiency is required, the defoaming points are concentrated, but the amplitude of the defoaming tool head is large, the defoaming effect is unstable, and the tool head is easy to break. The reason is that when the tool head is designed, the cavity surface design curve is unreasonable and the stress is large. If the defoaming area is pursued, the defoaming area increases and the defoaming effect drops sharply. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides ultrasonic defoaming equipment.
[0005] The utility model is implemented by the following technical scheme: ultrasonic defoaming equipment, including a transducer, a connecting column is arranged at the lower end of the transducer, the surface of the connecting column is fixedly connected to a limiting plate, the surface of the transducer is fixedly connected to a first flange, the surface of the connecting column is fixedly connected to a connecting piece, a second flange is arranged at the lower end of the first flange, a limiting groove is provided on the inner wall of the second flange, a tool head is fixedly connected to the bottom of the connecting column, and a curved surface is arranged at the lower end of the tool head.
[0006] Through the above technical solution, the transducer converts electrical energy into ultrasonic energy and transmits it to the tool head through the connecting column. Under the action of the high-energy ultrasonic field, the bubbles in the filling are subjected to strong compression and expansion, causing the bubbles to burst, thereby achieving a defoaming effect. Through the curved surface at the lower end of the tool head, the stress can be reduced to a minimum, greatly extending the service life. At the same time, the operating power of the equipment can be reduced by 25%, reducing costs and increasing efficiency.
[0007] As a further improvement of the above solution, the first flange and the second flange are threadedly connected by bolts, and the surface of the limiting plate is in contact with the inner wall of the limiting groove.
[0008] Through the above technical solution, the first flange and the second flange are connected by bolts, which facilitates the installation and fixation of the connecting column.
[0009] As a further improvement of the above solution, the size of the limiting plate is matched with the size of the limiting groove.
[0010] Through the above technical solution, the position of the limit plate is limited by the limit groove, which facilitates the subsequent installation and fixation of the connecting column, ensures the stability of the equipment during operation, and reduces the looseness problem caused by vibration.
[0011] As a further improvement of the above solution, the connecting member and the inner wall of the second flange are provided with corresponding mounting holes, and the connecting member is located at the upper end of the limiting plate.
[0012] With the above technical solution, the connection and fixation are performed through the connecting piece and the mounting hole on the inner wall of the second flange by bolts, thereby improving the stability during use.
[0013] As a further improvement of the above solution, a mounting piece is installed on the top of the transducer, and a transducer cooling air inlet pipe is installed on the inner wall of the mounting piece.
[0014] Through the above technical solution, the transducer cooling air intake pipe is connected to the external cooling device, which effectively reduces the temperature of the transducer during use and prolongs the service life of the transducer.
[0015] As a further improvement of the above solution, a transducer cooling outlet pipe is installed on the inner wall of the mounting member.
[0016] Through the above technical solution, cooling gas is introduced into the transducer cooling air inlet pipe, passes through the inside of the transducer, and is discharged from the transducer cooling air outlet pipe.
[0017] As a further improvement of the above solution, the bottoms of the transducer cooling air inlet pipe and the transducer cooling air outlet pipe are both connected to the interior of the transducer.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] The utility model can reduce stress to a minimum and greatly extend the service life by optimizing the shape design of the tool head, and at the same time can reduce the working power of the equipment by 25%, reduce costs and increase efficiency, improve production efficiency, reduce production costs, concentrate the defoaming amplitude, so that the defoaming equipment can work continuously, changing the previous pulse working mode adopted to ensure safety and reliability, and various products can be produced without adjusting the production line speed.
