Description

Technical Field

[0001] The invention relates to the technical field of toothpaste production technology, in particular to a degassing device and a degassing method thereof. Background Art

[0002] With the improvement of health awareness and the change of consumption concepts in modern society, consumers pay more and more attention to oral care, which has led to the rapid development of the toothpaste market. The types of toothpaste are becoming more diversified, and consumers' functional requirements for toothpaste are becoming more and more abundant. The production process of toothpaste includes steps such as metering, gelatin making, paste kneading, grinding, degassing, and aging. Among them, the degassing step can discharge the foam in the toothpaste paste to improve the quality of the toothpaste paste.

[0003] During the mixing process of the raw materials of the semi-finished paste, the surfactant in the raw materials reacts with water and air, forming a large number of bubbles in the semi-finished paste. These bubbles will affect the stability of the paste, and the bubbles need to be removed from the paste. Generally, the semi-finished paste needs to be placed in a container, and the vacuum pump is started to extract the air in the container. The bubbles in the semi-finished paste will gradually form a large amount of foam as the vacuum negative pressure increases. Due to the limited space in the container, in order to prevent the container from being filled with too much foam, the vacuum negative pressure needs to be controlled to prevent the rapid generation of foam.

[0004] However, when the vacuum pump is used to extract air, manual observation is generally used, and the extraction is stopped when the foam surface rises to a certain height. However, it is also easy to extract the semi-finished toothpaste during the extraction process, so how to achieve automatic elimination of foam is a difficult problem faced by the current process.

[0040] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0041] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.

[0042] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] It should be noted that when a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there can be a central component; when an component is considered to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time; when an component is considered to be "installed on" another component, it can be directly installed on the other component or there can be a central component at the same time. When an component is considered to be "set on" another component, it can be directly set on the other component or there can be a central component at the same time.

[0044] The present invention provides a degassing device 100, such as Figures 1 to 5 As shown, it includes a tank body 1, a cover body 2, a monitoring component 6, and a vacuum pump 8. The tank body 1 has a first opening 4. The cover body 2 is detachably mounted on the tank body 1 and is used to be sealed and connected with the tank body 1. A closed degassing chamber 11 is formed in the tank body 1. The vacuum pump 8 is connected to the degassing chamber 11 through the first opening 4. The monitoring component 6 is mounted on the cover body 2. The monitoring component 6 is electrically connected to the vacuum pump 8. The monitoring component 6 is used to monitor the height position of the foam liquid level. During installation, the tank body 1 can be placed on a workbench 9, and the vacuum pump 8 can be placed under the workbench 9.

[0045] Specifically, under normal conditions, the pressure inside and outside the foam is in a balanced state; when the vacuum pump 8 is evacuating air, the degassing chamber 11 is in a vacuum state, the external pressure of the foam decreases, and the gas pressure inside the foam remains unchanged. At this time, a pressure difference is generated inside and outside the foam, causing the gas inside the foam to move toward the vacuum position due to the pressure and fill the vacuum area near the foam, causing the foam to expand or break. Moreover, the gas has a tendency to diffuse from a position with high pressure to a position with low pressure, and the semi-finished paste 35 continues to generate foam, and the air in the degassing chamber 11 is continuously discharged from the first port 4, causing the foam surface to move upward when the degassing chamber 11 is evacuated.

[0046] When the foam surface 351 rises to the first preset height 352, the state or position of the foam surface 351 is detected by the monitoring component 6, and a first electrical signal is generated. The first electrical signal can directly drive the vacuum pump 8 to stop working, or the first electrical signal is transmitted to the controller, and the controller is used to drive the vacuum pump 8 to stop working. When the vacuum pump 8 stops working, the degassing chamber 11 is depressurized, and the air outside the tank body 1 enters the degassing chamber 11. The air enters the degassing chamber, eliminating the pressure difference of the foam, and the foam surface drops.

[0047] Moreover, the suction force of the first port 4 disappears, and there is stickiness between adjacent foams, so the foam will automatically fall due to its own weight. After the foam surface 351 drops to the second preset height 353, the state or position of the foam surface 351 is detected by the monitoring component 6, causing the monitoring component 6 to generate a second electrical signal. The second electrical signal drives the vacuum pump 8 to start again, so that the vacuum pump 8 extracts the air in the degassing chamber 11 again. Such repeated operations can realize the continuous and uninterrupted generation of foam for the semi-finished toothpaste 35, and after the gas in the foam is extracted, the foam breaks, so that the automatic degassing operation of the semi-finished paste 35 can be realized without manual observation of the height of the foam surface 351.

[0048] Preferably, the first port 4 can be set at the upper end of the tank body 1, and the semi-finished paste 35 can be set at the lower end of the tank body 1. Since the semi-finished paste 35 has viscosity or its own weight, there is still a certain distance between the semi-finished paste 35 and the first port 4 in the degassing chamber 11. Therefore, the suction force generated by the first port 4 cannot suck the semi-finished paste 35 out of the degassing chamber 11, so as to avoid affecting the automatic degassing operation of the semi-finished paste 35.

[0049] In some embodiments, the degassing device 100 further comprises a solenoid valve 41, which is installed at the first port 4, the first end of the solenoid valve 41 is connected to the first port 4, the second end of the solenoid valve 41 is connected to the vacuum pump 8, and the solenoid valve 41 is electrically connected to the monitoring component 6. Specifically, the monitoring component 6 is used to send the first electrical signal and the second electrical signal to the solenoid valve 41, so as to control the opening and closing of the solenoid valve 41. When the solenoid valve 41 receives the first electrical signal, the air pipe 81 is closed, so that the vacuum pump 8 is disconnected from the first port 4, and the degassing chamber 11 is not evacuated, and the foam surface 351 drops; when the solenoid valve 41 receives the second electrical signal, the air pipe 81 is opened, so that the vacuum pump 8 is connected to the first port 4, and the vacuum pump 8 extracts the air from the degassing chamber 11, without closing and opening the vacuum pump 8, thereby improving the convenience of operation.

[0050] In some embodiments, the tank body 1 also has a second port 5, which is connected to the degassing chamber 11; the degassing equipment 100 also includes a pressure detector 52 and a pressure relief valve 51, the pressure detector 52 is installed on the cover body 2, and the detection end of the pressure detector 52 is arranged in the degassing chamber 11; the pressure relief valve 51 is installed at the second port 5, and the pressure detector 52 is electrically connected to the pressure relief valve 51; when the pressure detector 52 detects that the actual pressure value of the degassing chamber 11 is less than the warning threshold, the pressure detector 52 is used to drive the pressure relief valve 51 to open, so that the actual pressure value of the degassing chamber 11 is greater than or equal to the warning threshold.

[0051] Specifically, when the monitoring component 6 controls the solenoid valve 41 or the vacuum pump 8 to operate, the air in the degassing chamber 11 is extracted by the vacuum pump 8, and the degassing chamber 11 is in a negative pressure state. The actual air pressure value in the degassing chamber 11 is less than the standard atmospheric pressure outside the degassing chamber 11, and there is a certain pressure difference inside and outside the tank body 1. Under the action of the pressure difference, the bubbles in the semi-finished paste 35 form foam, and as the pressure difference increases, the foam gradually expands. When the infrared sensor 61 detects that the liquid level of the foam reaches the first preset height 352, the vacuum pump 8 is driven to stop working or close the connecting pipeline, and the pressure relief valve 51 is opened to allow outside air to enter the degassing chamber 11, reduce the pressure difference of the bubbles in the semi-finished paste 35, reduce the height of the foam, and remove a part of the bubbles in the semi-finished paste 35. When the foam surface of the semi-finished paste 35 drops to the second preset height 353, the infrared sensor 61 drives the vacuum pump 8 again or opens the connecting pipeline to extract and discharge the air in the degassing chamber 11, and the bubbles in the semi-finished paste 35 form foam again. As the vacuum pressure difference increases, the foam gradually expands again, and this cycle is repeated until the bubbles in the semi-finished paste 35 are completely removed.

[0052] Preferably, the monitoring component 6 can also be electrically connected to the pressure relief valve 51, or the monitoring component 6 controls the pressure relief valve 51 through a controller. When the monitoring component 6 generates a first electrical signal, the vacuum pump 8 stops drawing vacuum into the tank body 1. At this time, the first electrical signal drives the pressure relief valve 51 to open. Because there is a pressure difference between the inside and outside of the tank body 1, air automatically enters the tank body 1 through the second port 5, filling the tank body 1 with air, and the vacuum negative pressure in the degassing chamber 11 becomes smaller, the foam gradually shrinks, and the foam surface drops.

[0053] Preferably, the monitoring component 6 includes at least two infrared sensors 61, and the infrared sensors 61 are used to generate infrared light so that the infrared light can detect the height of the foam surface 351 in the degassing chamber 11 and generate a first electrical signal or a second electrical signal. Specifically, two infrared sensors are used mainly to enable the other infrared sensor to monitor the foam surface 351 after one of the infrared sensors fails, so that the monitoring component 6 can normally transmit the first electrical signal and the second electrical signal to the controller or the pressure relief valve 51 or the vacuum pump 8. If a single infrared sensor is used, the infrared sensor fails, which will cause the vacuum pump 8 to continuously extract air from the degassing chamber 11. The pressure difference between the inside and outside of the tank body 1 reaches a certain value, and the tank body 1 will be squeezed by the external air pressure, causing the tank body 1 to deform and damage the degassing device 100. Therefore, it is very necessary to use two infrared sensors 61. The probability of two infrared sensors failing at the same time is small, and two infrared sensors can avoid the occurrence of the above-mentioned accidents.

[0054] Preferably, the cover 2 is at least partially made of a transparent material, and the transparent material is made into a perspective window 21, so that the infrared light of the infrared sensor can be emitted into the tank body 1 through the perspective window 21 and monitor the height position of the foam surface 351. The infrared sensor is a sensor that uses infrared rays to process data and has the advantages of high sensitivity. The infrared sensor can control the operation of the driving device, such as the vacuum pump 8 and the pressure relief valve 51.

[0055] Preferably, the degassing device 100 further has a sealing assembly 10, which includes a sealing rubber ring (not shown in the figure), the cover body 2 is connected to the tank body 1, the sealing rubber ring is arranged between the lower end surface of the cover body 2 and the upper end surface of the tank body 1, and the outer wall of the sealing rubber ring abuts against the cover body 2 and the tank body 1. Specifically, a sealing rubber ring is used between the cover body 2 and the tank body 1, and when the cover body 2 and the tank body 1 are fixed, the tank body 1 and the cover body 2 are flexibly matched, so that the gap between the cover body 2 and the tank body 1 can be eliminated, and the sealing of the degassing chamber 11 can be improved.

[0056] Preferably, Figure 6As shown, the sealing assembly 10 also includes a support seat 101, a connecting rod 102, a connecting sleeve 103, a connecting screw 104, and an adjusting piece 105. The cover body 2 is hinged to the first end of the tank body 1, the support seat 101 is installed at the second end of the tank body 1, the first end of the connecting rod 102 is rotatably matched with the support seat 101, the connecting sleeve 103 is installed on the side wall of the cover body 2, the connecting sleeve 103 is sleeved on the outside of the connecting rod 102 and movably matched with the connecting rod 102, and the second end of the connecting rod 102 is provided with an internal thread; the adjusting piece 105 is installed at the first end of the connecting screw 104, the second end of the connecting screw 104 has an external thread, the second end of the connecting screw 104 is inserted into the connecting sleeve 103 and threadedly matched with the connecting rod 102, and the connecting screw 104 is used to abut against the connecting sleeve 103.

[0057] Specifically, the connecting rod 102 is fixed to the side wall of the tank body 1 through the support seat 101. When the cover body 2 is placed on the tank body 1 and buckled with the tank body 1, the sealing rubber ring is arranged between the cover body 2 and the tank body 1. One end of the connecting rod 102 extends into the connecting sleeve 103. After the connecting screw 104 is threadedly connected with the connecting rod 102 in the connecting sleeve 103, the adjusting member 105 is rotated to drive the connecting screw 104 to rotate clockwise or counterclockwise. The clockwise or counterclockwise rotation is used to open or close the degassing chamber 11. After the connecting screw 104 rotates, the largest end of the connecting screw 104 can be used to abut against the connecting sleeve 103, so that the connecting sleeve 103 moves close to the tank body 1, and drives the cover body 2 to abut against the tank body 1 to achieve sealing. In this embodiment, this sealing assembly 10 can have multiple groups, and the multiple groups of sealing assemblies 10 are arranged on the circumference of the cover body 2 to squeeze the cover body 2 from different directions of the cover body 2 to improve the sealing of the degassing chamber 11.

[0058] In some embodiments, Figure 2 and Figure 7 As shown, the degassing device 100 also includes a support frame 3 and a content bag 34. The support frame 3 is movably arranged in the degassing chamber 11. There is a gap between the support frame 3 and the inner wall of the tank body 1. The support member 3 has a accommodating chamber 31, and the content bag 34 is arranged in the accommodating chamber 31; the support frame 3 includes a plurality of support columns 33 and two support rings 32. The two ends of the plurality of support columns 33 are respectively installed on the two support rings 32. The two support rings 32 are arranged opposite to each other, and the accommodating chamber 31 is formed between the inner sides of the support rings 32 and the inner sides of the support columns 33.

[0059] Specifically, the container bag 34 is used to contain the semi-finished paste 35, and the semi-finished paste 35 is placed in the receiving chamber 31 of the support frame 3 through the container bag 34, so as to avoid direct contact between the semi-finished paste 35 and the inner wall of the tank body 1, and to avoid the semi-finished paste 35 being retained in the tank body 1 after the degassing operation of the semi-finished paste 35 is completed, so as to avoid making the tank body 1 difficult to clean. Moreover, the support column 33 can block the semi-finished paste 35, and at the same time, when the container bag 34 is placed, the opening of the container bag 34 is placed outside the support ring 32, so that the semi-finished paste 35 is stably located in the receiving chamber 31. Moreover, the semi-finished paste 35 is in a paste-like substance, and its fluidity has certain limitations, and it cannot overflow from the container bag 34 to the outside.

[0060] In some embodiments, the tank body 1 further has a third port 7 and a cleaning valve 71. The third port 7 is disposed at the bottom of the tank body 1 and is connected to the degassing chamber 11. The cleaning valve 71 is installed at the third port 7. Specifically, after the degassing device 100 completes the degassing of the semi-finished paste 35, the support frame 3 can be removed, and the tank body 1 can be cleaned. The cleaning valve 71 is opened, and the sewage after cleaning can be discharged through the third port 7; when the degassing device 100 is in operation, the cleaning valve 71 closes the third port 7.

[0061] Moreover, this embodiment also proposes a degassing method, comprising the following steps:

[0062] S1, placing the stirred semi-finished paste 35 in the sealed degassing chamber 11, the semi-finished paste 35 generates bubbles, and the vacuum pump 8 is started to extract the air in the degassing chamber 11 and the foam, and the foam surface 351 moves upward;

[0063] S2, using the monitoring component 6 to monitor the foam surface 351 moving to the first preset height 352, the monitoring component 6 generates a first electrical signal, and the first electrical signal is used to control the vacuum pump 8 to stop operating;

[0064] S3, the degassing chamber 11 is depressurized, and air enters the degassing chamber 11;

[0065] S4, after the air in the foam is extracted, the foam breaks, and the foam surface 351 drops. The monitoring component 6 monitors that the foam surface 351 moves to the second preset height 353, and the monitoring component 6 generates a second electrical signal, which is used to control the vacuum pump 8 to start again;

[0066] S5, repeating the above steps, the semi-finished paste 35 automatically completes the degassing operation in the degassing chamber 11.

[0067] By adopting the degassing method, it is possible to realize automatic degassing operation without the need for manual observation of the foam surface height of the degassing device 100 .
