DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0020] An embodiment of the utility model, as Figure 1 and Figure 2 As shown, the defoaming device includes a rotating platform 2 arranged on a frame 1 and a storage box 3 arranged above the rotating platform 2. A horizontal support table 34 is installed at the center of the storage box 3 through a support rod. A feed control valve 35 is installed on the support table 34. A liquid partition wall 31 surrounded by a stainless steel ring is arranged in the storage box 3. A clean material area is formed between the liquid partition wall 31 and the outer wall of the storage box 3. An exhaust pipe 32 close to the liquid partition wall 31 and a quantitative cup 33 located outside the exhaust pipe 32 are arranged in the clean material area. A filling valve 38 is connected to the bottom of the quantitative cup 33. Each filling valve 38 is connected to the bottom of the quantitative cup 33. A bottle lifting mechanism 4 installed on the rotating platform 2 is provided at the bottom of the filling valve 38. A bubble penetration prevention wall is installed in the storage box 3, surrounded by a stainless steel circle, whose height is higher than the set liquid level height. The filling valve 38 is installed on the periphery of the central liquid partition wall 31. The material can flow into the filling valve 38 through the channel 30 at the bottom of the liquid partition wall 31. Since air bubbles are lighter than materials, the bubbles will run outward until they run out of the liquid surface. There are no bubbles in the liquid at the bottom of the storage box 3, and it becomes pure liquid and flows into the filling area to ensure that the liquid is filled into the container, achieving consistent measurement without deviation.

[0021] A feed pipe connected to a feed control valve 35 is provided below the support table 34, and a lateral discharge port 36 with two sides connected is provided at the bottom of the feed pipe. A transverse pipe is installed at the discharge end of the feed pipe to change the final discharge port from a one-way port to two lateral discharge ports to reduce impact force and bubble generation.

[0022] A liquid level float 37 installed at the bottom of the support table 34 is provided on the side of the feed pipe. A proximity switch is provided on the liquid level float 37. The liquid level height is detected by the proximity switch, and the signal is transmitted to the PLC computer through the transmission module connected to the slip ring 7 to control the opening and closing of the feed valve, and finally reach the liquid level and control it on the set liquid level line.

[0023] At least four groups of bottom channels 30 are evenly distributed in the circumferential direction and connected to the clean material area at the bottom of the liquid partition wall 31. Since air bubbles are lighter than materials, the bubbles will run outward until they run out of the liquid surface. At this time, there are no bubbles in the liquid at the bottom of the storage box, and it becomes pure liquid, which flows into the filling area from the bottom channel 30 to ensure that the liquid is filled into the container.

[0024] The height of the quantitative cup 33 is lower than that of the liquid isolation wall 31 , ensuring that the pure liquid material can smoothly enter the filling valve 38 from the quantitative cup 33 .

[0025] like Figure 3 As shown, the bottle supporting and lifting mechanism 4 includes a bottle supporting disc 41 and a bottle body 2 arranged on the bottle supporting disc 41. A claw 43 for clamping the bottle body 42 is installed on the top of the bottle supporting disc 41. The side of the bottle supporting disc 41 is slidably sleeved on a positioning column 21 fixed on the surface of the rotating platform 2. The bottom of the bottle supporting disc 41 is connected to a lifting rod 44 passing through a sliding sleeve installed on the rotating platform 2. The bottom of the lifting rod 44 is connected to a pulley 45 through a rotating shaft. Figure 4 As shown, the pulley 45 abuts against the cam ring 11 mounted on the surface of the frame 1.

[0026] A gear transmission mechanism 6 is arranged on the surface of the frame 1, and a slip ring 7 connected to the rotating platform 2 is arranged in the center of the gear transmission mechanism 6. The top of the rotating platform 2 is connected to the storage box 3 through the support assembly 5. The gear transmission mechanism 6 has an engaged gear set and a gear ring arranged on the outside of the gear set and engaged with the gear set. The top of the gear ring is connected to the rotating platform through a connecting rod. The gear set is driven to rotate through the driving structure, which drives the gear ring to perform circular motion and rotates the rotating platform at the same time.

[0027] The working principle of this embodiment is as follows: the material enters the storage box from the horizontal discharge port at the bottom of the feed pipe. Since air bubbles are lighter than the material, the bubbles will run upward until they run out of the liquid surface. The pure liquid material enters the clean material area from the bottom channel. When the liquid level in the clean material area rises to exceed the top of the quantitative cup, the material enters the filling valve. When the pulley at the bottom of the bottle lifting mechanism passes the raised part on the cam ring, the bottle body rises and abuts against the filling valve to complete the filling operation.

[0028] Several points that need to be explained are: First, in the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, and can be mechanical or electrical connections, or internal connectivity between two elements, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may change; secondly, in this article, relational terms such as first and second, etc. are only used to distinguish one entity from another, and do not necessarily require or imply that there is any such actual relationship or order between these entities.
