Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, specifically to an ultrasonic cleaning device for a sand core funnel. Background Technology

[0002] A sand core funnel is a laboratory filtration device made of porous glass or ceramic. Its core is a sintered sand core filter plate with uniform pores and corrosion resistance, suitable for precision filtration and vacuum filtration. Sand core funnels must be cleaned regularly to maintain their filtration performance. Clogged micropores can lead to decreased flow rates or even complete failure, affecting the accuracy of experimental data. Organic residues may breed bacteria and contaminate subsequent samples, while inorganic salt deposits can alter the pore structure of the filter membrane. Traditional sand core funnels are mostly cleaned using backwashing. While backwashing effectively removes clogging, it cannot remove deep-seated residues, leading to a gradual decline in the filtration performance of the sand core funnel. Utility Model Content

[0003] The purpose of this invention is to provide an ultrasonic cleaning device for sand core funnels, in order to solve the problem mentioned in the background art that traditional sand core funnels are mostly cleaned by backwashing. While backwashing can effectively clean the blockage of sand core funnels, it cannot clean deep-seated residues, leading to a gradual decline in the filtration performance of the sand core funnel.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic cleaning device for a sand core funnel, comprising a cleaning chamber, ultrasonic transducers evenly arranged on the lower surface of the cleaning chamber, a vertical high-pressure pump located on one side inside the cleaning chamber, a main pipe connected to the vertical high-pressure pump at the middle position inside the cleaning chamber, cleaning nozzles located inside the cleaning chamber and on both sides of the main pipe, the cleaning nozzles being connected to the main pipe via secondary pipes, a limiting seat located inside the cleaning chamber at a position corresponding to the cleaning nozzle, a through groove being formed at the upper end of the limiting seat, and an installation frame located at the lower end inside the cleaning chamber.

[0005] Preferably, the lower end of the cleaning chamber is provided with a support frame, which lifts the cleaning chamber off the ground to provide space for the installation of the ultrasonic transducer. The outer surface edge of the cleaning chamber is provided with a reinforcing frame, and the lower end of the reinforcing frame is fixedly connected to the support frame.

[0006] Preferably, the output end of the vertical high-pressure pump is connected to the main pipeline via a connecting flange, and the input end of the vertical high-pressure pump is connected to the inner cavity of the cleaning tank.

[0007] Preferably, the vertical high-pressure pump, the main pipeline, the cleaning nozzle, the auxiliary pipeline, and the limiting seat are all fixedly connected to the upper surface of the mounting frame.

[0008] Preferably, the limiting seat has a limiting groove inside, the limiting groove is correspondingly arranged with the cleaning nozzle, and the through groove is connected to the limiting groove.

Detailed Implementation

[0012] 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.

[0013] Please see Figure 1-5This utility model provides an ultrasonic cleaning device for sand core funnels, including a cleaning chamber 1. Ultrasonic transducers 2 are evenly arranged on the lower surface of the cleaning chamber 1. A vertical high-pressure pump 3 is provided on one side inside the cleaning chamber 1. A main pipe 4 is connected to the vertical high-pressure pump 3 at the middle position inside the cleaning chamber 1. Cleaning nozzles 5 are provided inside the cleaning chamber 1 and on both sides of the main pipe 4. The cleaning nozzles 5 are connected to the main pipe 4 through a secondary pipe 6. A limiting seat 7 is provided inside the cleaning chamber 1 at the position corresponding to the cleaning nozzle 5. A through groove 8 is opened at the upper end of the limiting seat 7. An installation frame 9 is provided at the lower end inside the cleaning chamber 1.

[0014] In use, an ultrasonic transducer 2 is installed at the lower end of the cleaning chamber 1. The ultrasonic transducer 2 generates ultrasonic vibrations in the cleaning fluid inside the cleaning chamber 1. An installation frame 9 is installed inside the cleaning chamber 1 to fix the vertical high-pressure pump 3, main pipe 4, cleaning nozzle 5, auxiliary pipe 6, and limiting seat 7 to the installation frame 9. This avoids directly fixing the vertical high-pressure pump 3, main pipe 4, cleaning nozzle 5, auxiliary pipe 6, and limiting seat 7 to the lower wall of the cleaning chamber 1, thus preventing the ultrasonic transducer 2 from generating ultrasonic waves during operation. The vibration damages the structure of the vertical high-pressure pump 3, main pipe 4, cleaning nozzle 5, auxiliary pipe 6 and limit seat 7. The sand core funnel to be cleaned is placed inside the limit seat 7 through the through groove 8. The vertical high-pressure pump 3 is installed inside the cleaning chamber 1. When the vertical high-pressure pump 3 is working, it draws the cleaning fluid inside the cleaning chamber 1 and sprays it out through the main pipe 4 and auxiliary pipe 6 and then through the cleaning nozzle 5. The sprayed cleaning fluid is sprayed into the sand core funnel fixed in the limit seat 7, and the sand core funnel is cleaned by ultrasonic waves and rinsing at the same time.

[0015] The lower end of the cleaning chamber 1 is provided with a support frame 10. The support frame 10 lifts the cleaning chamber 1 off the ground to provide space for the installation of the ultrasonic transducer 2. The outer surface edge of the cleaning chamber 1 is provided with a reinforcing frame 11. The lower end of the reinforcing frame 11 is fixedly connected to the support frame 10. The support frame 10 at the lower end of the cleaning chamber 1 provides space for the installation of the ultrasonic transducer 2. The reinforcing frame 11 on the outer surface of the cleaning chamber 1 improves the structural strength of the cleaning chamber 1.

[0016] The output end of the vertical high-pressure pump 3 is connected to the main pipeline 4 via a connecting flange 12, and the input end of the vertical high-pressure pump 3 is connected to the inner cavity of the cleaning tank 1. The vertical high-pressure pump 3 is connected to the main pipeline 4 via the connecting flange 12, and can be replaced when the vertical high-pressure pump 3 is damaged.

[0017] The vertical high-pressure pump 3, the main pipe 4, the cleaning nozzle 5, the auxiliary pipe 6, and the limiting seat 7 are all fixedly connected to the upper surface of the mounting frame 9, so as to avoid directly fixing the vertical high-pressure pump 3, the main pipe 4, the cleaning nozzle 5, the auxiliary pipe 6, and the limiting seat 7 to the lower wall of the cleaning box 1, and to provide support for the above structures.

[0018] The limiting seat 7 has a limiting groove 13 inside, which is correspondingly set with the cleaning nozzle 5. The through groove 8 is connected to the limiting groove 13. The limiting seat 7 uses the limiting groove 13 structure to lock the funnel section of the sand core funnel to ensure a firm fixation.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
