Description

Technical Field

[0001] This utility model relates to the field of laundry detergent technology, specifically to a structure for preventing foam overflow in laundry detergent production. Background Technology

[0002] In the production of laundry detergent, reaction vessels are often used for stirring and mixing raw materials. However, due to the characteristics of surfactants and other components in the concentrate, a large amount of foam is generated during stirring. This foam easily overflows from the feed inlet of the reaction vessel, resulting in waste of raw materials.

[0003] In existing technologies, some reactors use defoamers to suppress foam generation in order to solve the problem of foam overflow. However, the addition of defoamers may alter the formulation characteristics of the laundry detergent, affecting product quality. Secondly, the use of defoamers increases production costs and is not suitable for all types of laundry detergent formulations. Furthermore, some equipment uses increased reactor volume or simple overflow troughs to contain foam, but these methods are only temporary solutions and fail to effectively address the problem of rapid foam accumulation and overflow. They also occupy additional space, increasing equipment costs. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a foam-preventing overflow structure for laundry detergent production, thus solving the problem of rapid foam accumulation and overflow during the existing laundry detergent mixing process.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A structure for preventing foam overflow in laundry detergent production, comprising:

[0006] A reaction vessel, comprising an outer shell and a reaction liner, wherein the reaction liner is placed inside the outer shell and a reserved space is provided between the reaction liner and the outer shell;

[0007] A through hole is provided on the upper side wall of the reaction liner;

[0008] A stirring assembly is disposed on the reaction vessel, wherein the stirring assembly includes a rotating stirring shaft disposed inside the reaction vessel;

[0009] An air blowing assembly includes a blower, a duct, a straight air blowing pipe, and a curved air blowing pipe. The blower is located at the top of the reaction chamber. One end of the duct is located at the output end of the blower. One end of the straight air blowing pipe is rotatably connected to the inside of the reaction chamber via a rotating shaft. The other end of the straight air blowing pipe is rotatably connected to the other end of the duct via a rotating shaft. The curved air blowing pipe is fixed to the end of the straight air blowing pipe located in the reaction chamber.

[0010] A linkage component is installed between the stirring shaft and the air outlet straight pipe, which is used to drive the air blowing straight pipe and the air blowing curved pipe to rotate.

[0011] The beneficial effects of this utility model are:

[0012] 1) A storage space is reserved between the outer shell of the reactor and the inner liner of the reactor, and a through hole is opened on the upper side wall of the inner liner of the reactor. The foam generated during the stirring and mixing process can flow into the storage space through the through hole for storage, avoiding the foam from overflowing from the feed port of the reactor. This not only effectively reduces the waste of laundry detergent concentrate and lowers production costs, but also ensures the integrity of the formula ratio. A blower is used to deliver positive pressure airflow to the blowing straight pipe and blowing bend pipe through the duct. The impact force of the positive pressure airflow quickly pushes the foam on the upper layer of the inner liner of the reactor towards the through hole, improving the efficiency of foam discharge through the through hole and reducing the accumulation of foam in the inner liner of the reactor. The active foam guiding mechanism effectively shortens the foam treatment time and improves the continuity of stirring and mixing.

[0013] 2) In addition, through the transmission of the linkage components, the rotational power of the stirring shaft can synchronously drive the straight air blowing pipe and the curved air blowing pipe to rotate, without the need for an additional power source, thus reducing energy consumption. The straight air blowing pipe is connected to the reaction tank and the guide tube through the rotating shaft. The curved air blowing pipe adopts a right-angle design, which enables the curved air blowing pipe to rotate 360° in the reaction tank and spray air simultaneously, which can expand the direction and range of air blowing and further enhance the foam discharge effect.

[0014] Based on the above technical solution, the present invention can be further improved as follows.

[0015] Furthermore, the stirring assembly also includes a drive motor, which is fixed to the top of the reaction vessel, wherein the drive end of the drive motor passes through the reaction vessel and is connected to the stirring shaft.

[0016] Furthermore, the linkage component includes a first pulley, a second pulley, and a linkage belt, with the first belt sleeved on the outside of the stirring shaft.

[0017] Furthermore, the second pulley is sleeved on the outside of the air blowing straight pipe, and the linkage belt is sleeved on the outside of the first pulley and the second pulley.

[0018] The beneficial effect of adopting the above-mentioned further solution is that after the drive motor is started, the drive end of the drive motor drives the stirring shaft to rotate. The first pulley sleeved on the outside of the stirring shaft rotates synchronously with the stirring shaft. The first pulley is connected to the second pulley sleeved on the outside of the air blowing pipe through the linkage belt. The linkage belt transmits the rotational power of the first pulley to the second pulley, driving the second pulley to rotate. The rotation of the second pulley further drives the air blowing pipe and its connected air blowing bend to rotate synchronously, so that the air blowing bend sprays air when it rotates in the reaction tank, and the direction of the airflow changes continuously with the rotation, thereby covering a wider area and effectively enhancing the foam discharge effect.

[0019] Furthermore, the bend is a right-angle bend. Attached Figure Description

[0025] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0026] In the production of laundry detergent, reaction vessels are often used for stirring and mixing raw materials. However, due to the characteristics of surfactants and other components in the concentrate, a large amount of foam is generated during stirring. This foam easily overflows from the feed inlet of the reaction vessel, resulting in waste of raw materials.

[0027] In existing technologies, some reactors use defoamers to suppress foam generation in order to solve the problem of foam overflow. However, the addition of defoamers may alter the formulation characteristics of the laundry detergent, affecting product quality. Secondly, the use of defoamers increases production costs and is not suitable for all types of laundry detergent formulations. Furthermore, some equipment uses increased reactor volume or simple overflow troughs to contain foam, but these methods are only temporary solutions and fail to effectively address the problem of rapid foam accumulation and overflow. They also occupy additional space and increase equipment costs. Therefore, the inventor has proposed a foam-proof overflow prevention structure for laundry detergent production to solve these problems.

[0028] The present invention provides the following preferred embodiments.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a structure for preventing foam overflow in laundry detergent production includes:

[0030] The reaction vessel 10 includes an outer shell and a reaction liner, the reaction liner is placed inside the outer shell, and a space is reserved between the reaction liner and the outer shell for receiving.

[0031] Through hole 20 is provided on the upper side wall of the reaction vessel;

[0032] A stirring assembly 30 is disposed on the reaction vessel, wherein the stirring assembly 30 includes a rotating stirring shaft 302 disposed inside the reaction vessel;

[0033] The air blowing assembly 40 includes a blower 401, a conduit 402, an air blowing straight pipe 403, and an air blowing bend 404. The blower 401 is located at the top of the reaction tank. One end of the conduit 402 is located at the output end of the blower 401. One end of the air blowing straight pipe 403 is rotatably connected to the inside of the reaction tank via a rotating shaft. The other end of the air blowing straight pipe 403 is rotatably connected to the other end of the conduit 402 via a rotating shaft. The air blowing bend 404 is fixed to one end of the air blowing straight pipe 403 located in the reaction tank.

[0034] Linkage component 50 is disposed between stirring shaft 302 and air outlet straight pipe, and is used to drive air blowing straight pipe 403 and air blowing curved pipe 404 to rotate.

[0035] A storage space is reserved between the outer shell of the reactor 10 and the inner liner of the reactor, and a through hole 20 is opened on the upper side wall of the inner liner of the reactor. The foam generated during the stirring and mixing process can flow into the storage space through the through hole 20 for storage, avoiding the foam from overflowing from the feed port of the reactor 10. This not only effectively reduces the waste of laundry detergent concentrate and lowers production costs, but also ensures the integrity of the formula ratio. The blower 401 delivers positive pressure airflow to the air blowing straight pipe 403 and air blowing bend 404 through the conduit 402. The impact force of the positive pressure airflow quickly pushes the foam on the upper layer of the inner liner of the reactor towards the through hole 20, improving the discharge efficiency of the foam through the through hole 20 and reducing the accumulation of foam in the inner liner of the reactor. The active foam guiding mechanism effectively shortens the foam processing time and improves the continuity of stirring and mixing.

[0036] In addition, through the transmission of the linkage component 50, the rotational power of the stirring shaft 302 can synchronously drive the straight air pipe 403 and the curved air pipe 404 to rotate, without the need for an additional power source, thus reducing energy consumption. The straight air pipe 403 is connected to the reaction liner and the conduit 402 through the rotating shaft. The curved air pipe 404 adopts a right-angle design, which enables the curved air pipe 404 to rotate 360° in the reaction liner and spray air simultaneously, which can expand the direction and range of airflow and further enhance the foam discharge effect.

[0037] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the stirring assembly 30 also includes a drive motor 301, which is fixed to the top of the reaction liner. The drive end of the drive motor 301 passes through the reaction liner and is connected to the stirring shaft 302. The linkage assembly 50 includes a first pulley 501, a second pulley 502, and a linkage belt 503. The first belt is sleeved on the outside of the stirring shaft 302, the second pulley 502 is sleeved on the outside of the air blowing pipe 403, and the linkage belt 503 is sleeved on the outside of the first pulley 501 and the second pulley 502.

[0038] After the drive motor 301 is started, the drive end of the drive motor 301 drives the stirring shaft 302 to rotate. The first pulley 501 sleeved on the outside of the stirring shaft 302 rotates synchronously with the stirring shaft 302. The first pulley 501 is connected to the second pulley 502 sleeved on the outside of the air blowing pipe 403 through the linkage belt 503. The linkage belt 503 transmits the rotational power of the first pulley 501 to the second pulley 502, driving the second pulley 502 to rotate. The rotation of the second pulley 502 further drives the air blowing pipe 403 and its connected air blowing bend 404 to rotate synchronously, so that the air blowing bend 404 sprays air when rotating in the reaction tank, and the direction of the airflow changes continuously with the rotation, thereby covering a wider area and effectively enhancing the foam discharge effect.

[0039] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the bend is a right-angle bend.

[0040] The specific working process of this utility model is as follows:

[0041] After the drive motor 301 is started, the drive end of the drive motor 301 drives the stirring shaft 302 to rotate. The first pulley 501 sleeved on the outside of the stirring shaft 302 rotates synchronously with the stirring shaft 302. The first pulley 501 is connected to the second pulley 502 sleeved on the outside of the air blowing pipe 403 through the linkage belt 503. The linkage belt 503 transmits the rotational power of the first pulley 501 to the second pulley 502, driving the second pulley 502 to rotate. The rotation of the second pulley 502 further drives the air blowing pipe 403 and its connected air blowing bend 404 to rotate synchronously, so that the air blowing bend 404 sprays air when rotating in the reaction tank, so that the direction of the airflow changes continuously with the rotation, thereby covering a wider area.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
