Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a Teflon valve body solvent cleaning machine system. Background Art

[0002] Teflon (PTFE) valve bodies are often used in industries with high requirements for chemical corrosion resistance, such as chemical, pharmaceutical, and food, due to their excellent corrosion resistance and high temperature resistance. However, during use, various chemical solvents, media, or solid deposits often remain on the surface of the Teflon valve body and in the valve cavity, affecting subsequent use or process safety.

[0003] The existing Teflon valve body cleaning method usually requires manual repeated immersion in a specific solvent or cleaning by high-pressure spraying, which not only consumes a lot of manpower, but also easily causes solvent waste and environmental pollution. However, using a special cleaning machine to perform efficient, safe, and automated solvent circulation cleaning of the Teflon valve body can significantly improve production efficiency and reduce labor costs. Therefore, a Teflon valve body solvent cleaning machine system with a simple structure, convenient control, safety, and reliability is needed. Utility Model Content

[0014] This Teflon valve body solvent cleaning machine system realizes the automatic cleaning of the valve body. The system adopts a dual-motor collaborative working mode. Motor M1 drives the turntable to rotate, and motor M2 controls the turntable to lift. Automatic cleaning is achieved through the cooperation of five functional circuits (immersion, turntable, lifting, lowering and timing circuit). The control circuit ensures the precise connection of the cleaning process through the cascade control of multiple groups of time relays: first, the immersion time of the valve body in the solvent is controlled, and then the turntable starts to rotate to increase the liquid flow rate. At the same time, the valve body is reciprocated in the solvent through the lifting mechanism to further enhance the cleaning effect. The system controls the overall operation cycle through the total timing circuit, realizing the automatic coordination of immersion, rotation and lifting actions, which not only ensures the adequacy of cleaning, but also avoids the uncertainty of manual operation. This design not only improves the cleaning efficiency and quality, but also reduces solvent waste and environmental pollution through programmed control. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0019] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, a Teflon valve body solvent cleaning machine system includes power supplies L1, L2, and L3. The power supplies L1, L2, and L3 are connected to an air switch QF. The air switch QF is used as a main switch to control the opening and closing of the entire circuit.

[0022] The air switch QF is connected with the main circuit and the control circuit.

[0023] The main circuit includes motor M1 and motor M2. Motor M1 is connected to contactor KM1. The operation and shutdown of motor M1 are realized by opening and closing contactor KM1. Motor M2 is connected to contactor KM2 and contactor KM3 which are connected in parallel. Contactor KM2 controls the forward rotation of motor M2, and contactor KM3 controls the reverse rotation of motor M2. Among them, motor M1 is a turntable motor, which is used to control the rotation of the valve body fixed on the turntable. Motor M2 is a lifting motor, which controls the lifting and lowering of the turntable through a chain or a transmission belt. Motor M2 rises when it rotates forward, and descends when it rotates reversely.

[0024] The control circuit includes a main switch SB1. The on / off state of the control circuit is switched by pressing the main switch SB1. The main switch SB1 is connected to a soaking circuit 1, a turntable circuit 2, a lifting circuit 3, a lowering circuit 4 and a timing circuit 5.

[0025] The soaking circuit 1 includes a switch SB2. The switch SB2 is connected in parallel with a switch KA1. The switch SB2 and the switch KA1 are connected together with a normally closed switch KT5. The normally closed switch KT5 is connected with a relay KA1 and a power-on delay time relay KT1 which are connected in parallel with each other.

[0026] As mentioned above, when the switch SB2 is pressed once until it is turned on, the current flows to the normally closed switch KT5, so that the time relay KT1 is energized for timing, and the relay KA1 is energized, so that the switch KA1 is normally closed. The timing time of the time relay KT1 is the required soaking time. The valve body is placed in the cleaning solvent, and its soaking time is controlled by the soaking circuit.

[0027] The turntable circuit 2 includes a normally open switch KT1. The normally open switch KT1 is connected to a normally closed switch KT2. The normally closed switch KT2 is connected to a relay KM1. At the same time, the normally closed switch KT2 is connected in parallel to a power-on delay time relay KT2. When the timing of the time relay KT1 ends, the normally open switch KT1 is closed, so that the relay KM1 is powered on, and the time relay KT2 starts timing. At this time, the motor M1 starts to work, the turntable starts to rotate, and the valve body rotates in the solvent, which improves the liquid flow of the solvent and improves the cleaning effect.

[0028] The lifting circuit 3 includes a normally open switch KT1. The normally open switch KT1 is connected to a normally closed switch KT4. The normally closed switch KT4 is connected to a normally closed switch KT3. The normally closed switch KT3 is connected to a relay KM2. At the same time, the normally closed switch KT3 is connected in parallel to a power-on delay time relay KT3.

[0029] As mentioned above, when the timing time of the time relay KT1 ends, the normally open switch KT1 in the lifting circuit is closed, so that the circuit is turned on, the relay KM2 is energized, and the time relay KT3 starts timing. The contactor KM2 is closed, so that the motor M2 rotates forward. The forward rotation of the motor M2 drives the turntable to move upward as a whole, and cooperates with the rotation of the turntable to move the valve body in the solvent horizontally and vertically, thereby increasing the flow rate of the solvent liquid and improving the cleaning effect.

[0030] When the timing of the time relay KT3 ends, the normally closed switch KT3 is disconnected and the motor M2 stops.

[0031] The descending circuit 4 includes a normally open switch KT1, a normally open switch KT3 connected to a normally open switch KT3, a normally open switch KT3 connected to a normally closed switch KT4, a normally closed switch KT4 connected to a relay KM3, and a normally closed switch KT4 connected in parallel to a power-on delay time relay KT4.

[0032] Through the above settings, when the timing of the time relay KT3 ends, the rising action stops, the normally open switch KT3 is closed, the relay KM3 is energized, the contactor KM3 is closed, and the motor M2 is reversed, so that the valve body moves downward. At the same time, the time relay KT4 starts timing. At the end of the timing, the normally closed switch KT4 in the descending circuit is disconnected, and the motor M2 stops. At the same time, the normally closed switch KT4 in the ascending circuit is disconnected, and the ascending circuit is reset. The motor M1 rotates forward.

[0033] The circulating ascending and descending circuits allow the turntable to rise and fall repeatedly in the solvent, thereby further improving the cleaning effect.

[0034] The timing circuit 5 includes a normally open switch KT1, and the normally open switch KT1 is connected to a power-on delay time relay KT5. When the soaking time is over, the normally open switch KT1 is closed, so that the time relay KT5 starts timing. When the timing is over, the normally closed switch KT5 in the soaking circuit is disconnected, so that the relay KA1 loses power, the switch KA1 is disconnected, and at the same time, the time relay KT1 loses power, so that the normally open switch KT1 in the turntable circuit, the lifting circuit, the lowering circuit and the timing circuit is disconnected, and the entire circuit stops running.

[0035] The Teflon valve body solvent cleaning machine system described in the present application utilizes a combination of multiple motors, contactors and time relays to achieve efficient and automated cleaning of the valve body, significantly improving the cleaning efficiency and cleaning quality.

[0036] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
