Description

Technical Field

[0001] This invention relates to the field of papermaking additives technology, specifically to an integrated vertical defoamer production line. Background Technology

[0002] Because air bubbles in paper pulp can increase paper defects and affect the quality of finished products, defoamers are needed to defoam it. Common types of defoamers include: (1) natural oils (such as soybean oil and corn oil); (2) polyether defoamers; (3) higher alcohols; (4) silicones; and (5) polyether-modified silicones.

[0003] Generally, defoamers need to be modified to improve their performance, such as to make them more resistant to high temperatures and alkalis. The production process of such liquid defoamers basically includes the following steps:

[0004] 1. Synthesis: Raw materials are added to a reaction vessel, and a synthesis reaction is carried out according to the reaction conditions to synthesize the effective substance;

[0005] 2. Mixing: Mix the active ingredient and the auxiliary agent or diluent thoroughly;

[0006] 3. Filtration: The mixture is filtered to separate impurities from the reactants;

[0007] 4. The filtered liquid is packaged as the finished product.

[0008] For example, to give silicone defoamers high-temperature and alkali-resistant properties, acrylates are used to modify them to produce acrylate-modified silicone liquid defoamers. The specific production process is as follows:

[0009] Step S1: Add acrylate monomers and organosilicon compounds to the reaction vessel in proportion, add appropriate amounts of initiator and reactants, and carry out monomer reaction through efficient stirring and reaction control to obtain the desired network structure polymer.

[0010] Step S2: Mix the polymer obtained in step S1 with surfactants, additives, etc. to obtain a defoamer;

[0011] Step S3: Centrifuge and filter the defoamer for purification.

[0012] The existing defoamer production lines mainly have the following problems:

[0013] 1. The deployment of multiple units on the ground requires a certain area of ​​production space, which will result in higher production and investment costs.

[0014] 2. The production of most defoamers involves a synthesis reaction process. Some require only one synthesis reaction, while others require two. The process involves mixing the two reactants and adding other additives before mixing them again. In existing technologies, continuous production lines generally require multiple reactors to carry out the synthesis reaction separately before feeding the mixture into a mixing reactor. This results in a large number of reactors, a large floor space, and high production and investment costs. Summary of the Invention

[0015] The purpose of this invention is to provide an integrated vertical defoamer production line, which reduces the requirements for production site area and solves the problems in the prior art.

[0016] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0017] An integrated vertical defoamer production line includes a reaction chamber, a storage tank, and a mixing tank arranged from top to bottom. The reaction chamber and mixing tank are equipped with a first and second agitator driven by a motor, respectively. The storage tank includes a reactant storage tank and an additive storage tank. A rotating drum is rotatably installed inside the reactant storage tank. A feed pipe at the top of the drum extends from the reactant storage tank and is rotatably connected to the discharge port of the reaction chamber. The discharge port is equipped with a valve. A rotating drum is also installed inside the additive storage tank. A feed pipe at the top of the drum extends from the additive storage tank and is rotatably connected to a vertical feed pipe fixed to the bottom of the reaction chamber. The vertical feed pipe has a feed inlet.

[0018] The drum sidewall is provided with filter holes, and the inner sidewall of the drum is provided with a filter screen; the bottom of the storage box is connected to the mixing box with a valve.

[0019] As a preferred technical solution, the valve is a metering valve.

[0020] As a preferred technical solution, one end of the first stirring paddle extends out of the reaction tank and is connected to a secondary driven gear I via an electromagnet. When the electromagnet is working, the secondary driven gear I is rigidly connected to the first stirring paddle on the same axis. When the electromagnet is not working, the secondary driven gear I is rotatably connected to the first stirring paddle on the same axis.

[0021] One end of the second stirring paddle extends out of the mixing chamber and is connected to a secondary driven gear II via an electromagnet. When the electromagnet is working, the secondary driven gear II is rigidly connected to the second stirring paddle on the same axis. When the electromagnet is not working, the secondary driven gear II is rotatably connected to the second stirring paddle on the same axis.

[0022] The secondary driven gear I is connected to the primary driven gear I by a chain, and the secondary driven gear II is connected to the primary driven gear II by a chain; the primary driven gear I, the primary driven gear II and the transmission gear are arranged coaxially, and the transmission gear rotates under the drive of the motor.

[0023] As a preferred technical solution, the other end of the first stirring paddle extends out of the reaction tank and is connected to a driven bevel gear I via an electromagnet. When the electromagnet is working, the driven bevel gear I is rigidly connected to the first stirring paddle on the same axis. When the electromagnet is not working, the driven bevel gear I is rotatably connected to the first stirring paddle on the same axis.

[0024] The other end of the second stirring paddle extends out of the mixing chamber and is connected to a driven bevel gear II via an electromagnet. When the electromagnet is working, the driven bevel gear II is rigidly connected to the second stirring paddle on the same axis. When the electromagnet is not working, the driven bevel gear II is rotatably connected to the second stirring paddle on the same axis.

[0025] Driven bevel gear I and driven bevel gear II are respectively meshed with driving bevel gear I and driving bevel gear II; driving bevel gear I, driving bevel gear II, and the three-stage driven gear are arranged coaxially;

[0026] The third-stage driven gear is connected to the fourth-stage driven gear I and the fourth-stage driven gear II via a transmission chain; the fourth-stage driven gear I and the fourth-stage driven gear II are respectively installed on the feed pipe of the drum of the reactant storage tank and the feed pipe of the drum of the auxiliary agent storage tank.

[0027] As a preferred technical solution, the fourth-stage driven gear I is connected to the feed pipe of the drum inside the reactant storage tank via an electromagnet. When the electromagnet is working, the fourth-stage driven gear I is rigidly connected to the feed pipe of the drum inside the reactant storage tank on the same axis; when the electromagnet is not working, the fourth-stage driven gear I is rotatably connected to the feed pipe of the drum inside the reactant storage tank on the same axis.

[0028] The fourth-stage driven gear II is connected to the feed pipe of the drum inside the additive storage tank via an electromagnet. When the electromagnet is working, the fourth-stage driven gear II is rigidly connected to the feed pipe of the drum inside the additive storage tank on the same axis. When the electromagnet is not working, the fourth-stage driven gear II is rotatably connected to the feed pipe of the drum inside the additive storage tank on the same axis.

[0029] As a preferred technical solution, the number of teeth of the fourth-stage driven gear I is greater than the number of teeth of the fourth-stage driven gear II.

[0030] The production method of defoamer on an integrated vertical defoamer production line includes the following processes:

[0031] (1) Add the reaction raw materials into the reaction tank and add the auxiliary agent into the drum of the auxiliary agent storage tank;

[0032] (2) At this time, the electromagnets at both ends of the first stirring paddle are working, the electromagnets at both ends of the second stirring paddle are not working, and the electromagnets set on the feed pipe of the rotating drum in the anti-additive storage tank are working.

[0033] The motor drives the first stirring paddle to rotate at a high speed to carry out the synthesis reaction; the driving bevel gear I meshes with the driven bevel gear I, the transmission shaft rotates, and thus the three-stage transmission gear rotates; at this time, it drives the drum inside the additive storage tank to work; thus, while carrying out the synthesis reaction, the operation of the first stirring paddle drives the additive storage tank to perform solid-liquid separation, separating impurities in the additives. When the drum has worked for a set time, the controller controls the electromagnet at the other end of the first stirring paddle to stop working; the electromagnet on the feed pipe of the drum inside the additive storage tank also stops working; at this time, the additive storage tank stops filtering.

[0034] (3) When the synthesis reaction is completed, the discharge valve in the reaction chamber is opened, and after the reactants enter the drum of the reactant storage tank, the discharge valve in the reaction chamber is closed. At this time, the electromagnets at both ends of the first stirring paddle are not working, and the electromagnets at both ends of the second stirring paddle are working. The electromagnets installed on the drum feed pipe in the auxiliary agent storage tank and the reactant storage tank are working. The connecting valves between the reactant storage tank, the auxiliary storage tank and the mixing tank are all opened. The motor works, driving the second stirring paddle to rotate, thereby driving the three-stage driven gear on the transmission shaft to rotate, driving the drum in the reactant storage tank to work at high speed for centrifugal discharge, and the auxiliary agent storage tank to work at low speed for discharge.

[0035] (4) The second stirring paddle continues to rotate, and the reactant storage tank and the auxiliary agent storage tank continuously discharge raw materials into the mixing tank. The stirring paddle in the mixing tank continues to work, which makes the mixing effect better. After the reactant storage tank and the auxiliary agent storage tank have finished discharging, the electromagnet at the other end of the second stirring paddle stops working, the electromagnet on the feed pipe of the drum of the reactant storage tank and the auxiliary agent storage tank also stops working, and the connecting valves between the reactant storage tank, the auxiliary agent storage tank and the mixing tank are all closed.

[0036] (5) After the mixing chamber has completed mixing, the mixing chamber valve is opened to discharge the material.

[0037] Compared with the prior art, the present invention has the following advantages:

[0038] 1. The present invention uses a vertical structure to make the defoamer production line vertically set up and integrated, saving floor space.

[0039] 2. In this invention, a storage tank is provided between the reaction tank and the mixing tank, and a rotating drum for solid-liquid separation is provided in the storage tank, so that the material is filtered to remove impurities before mixing, thus advancing the filtration process after mixing in the prior art.

[0040] 3. This invention is driven by a motor, and during the operation of the first stirring paddle in the reaction tank, the solid-liquid separation and impurity removal process of the additives is realized simultaneously, reducing the overall production process time, and combining the material storage with the solid-liquid separation process.

[0041] 4. In this invention, since the synthesis time in the reaction chamber is longer than the solid-liquid separation time, when the material in the reaction chamber is discharged into the drum of the reaction storage tank, the additive storage tank has already completed the solid-liquid separation. At this time, by utilizing the difference in the number of gears between the fourth-stage driven gear I and the fourth-stage driven gear II, the additive storage tank is in a low-speed discharge state, while the reactant storage tank is in a high-speed centrifugal separation discharge state. Moreover, the drum operates under the rotation control of the second stirring paddle, which means that the mixing tank is feeding and stirring at the same time, making it easier to mix evenly.

Detailed Implementation

[0045] The purpose of this invention is to overcome the defects of the prior art and provide an integrated vertical defoamer production line. The invention will be further described in detail below with reference to the embodiments.

[0046] like Figures 1-2 The integrated vertical defoamer production line shown includes a reaction chamber 1, a storage tank, and a mixing tank 6 arranged from top to bottom. The reaction chamber 1 is located above the storage tank, and the bottom of the storage tank is fixed to the mixing tank 6.

[0047] Furthermore, the storage bin is equipped with a rotating drum 5. The bottom of the rotating drum 5 is rotatably fixed to the bottom of the storage bin, and the top of the rotating drum 5 is a feed pipe that extends from the top of the storage bin.

[0048] The bottom of the reaction chamber 1 is equipped with a discharge port and a drain port, both of which are equipped with metering valves. The discharge port is connected to a funnel-shaped discharge pipe 13 located outside the reaction chamber 1. In this embodiment, the bottom of the reaction chamber 1 has one discharge port and one drain port. The discharge port is connected to the large-diameter opening of the funnel-shaped discharge pipe 13 located at the bottom of the reaction chamber 1.

[0049] The storage tanks include reactant storage tank 3 and auxiliary agent storage tank 4.

[0050] The feed pipe of the inner drum 5 of the reactant storage tank 3 and the small-diameter opening of the funnel-shaped discharge pipe 13 are rotatably connected by a sealed bearing.

[0051] The feed pipe of the inner drum 5 of the additive storage tank 4 is rotatably connected to the vertical feed pipe 19 fixed at the bottom of the outer side of the reactant storage tank 3 through a sealed bearing. The vertical feed pipe 19 is provided with a horizontal feed port.

[0052] The side wall of the drum 5 is provided with filter holes, and the inner side wall of the drum 5 is provided with a filter screen; the bottom of the drum 5 is provided with a discharge port, and the discharge port is provided with a valve, so that the inside of the drum 5 can be connected to the storage box through the discharge port, which facilitates the discharge of filter residue when rinsing the drum 5.

[0053] A first rotatable stirring paddle 2 is arranged horizontally inside the reaction chamber 1. Both ends of the first stirring paddle 2 protrude from the reaction chamber 1 and are rotatably connected to the reaction chamber 1. A second stirring paddle 7 is arranged horizontally inside the mixing chamber 6. Both ends of the second stirring paddle 7 protrude from the mixing chamber 6 and are rotatably connected to the mixing chamber 6.

[0054] Above the mixing tank 6 and below the reaction tank 1, a rotatable, horizontally mounted drive shaft is fixed to the frame. The drive shaft is equipped with a transmission gear 8, which is fitted and connected to a drive gear driven by a motor, causing the motor to drive the drive shaft to rotate. The drive shaft also has a primary driven gear I9 and a primary driven gear II10; when the drive shaft rotates, the primary driven gears I9 and II10 rotate accordingly.

[0055] A secondary driven gear I11 is provided at one end of the first stirring paddle 2 via a connecting member, and a secondary driven gear II12 is provided at one end of the second stirring paddle 7 via a connecting member.

[0056] The connecting component includes a limiting groove and an electromagnet located in the limiting groove. Specifically, an electromagnet is embedded in one end of the first stirring paddle 2, and an annular limiting groove is provided on the outer wall of the first stirring paddle 2. The secondary driven gear I11 is sleeved on the first stirring paddle 2 and located in the limiting groove, so that it corresponds to the position of the electromagnet. When the electromagnet is not working, the secondary driven gear I11 is rotatably connected to the first stirring paddle 2. When the electromagnet is working, the secondary driven gear I11 and the first stirring paddle 2 are rigidly connected.

[0057] The second stirring paddle 7 is connected to the secondary driven gear II12 in the same way, by means of an electromagnet embedded in the second stirring paddle 7, and its position is limited by a limiting groove.

[0058] Among them, the secondary driven gear I11 and the aforementioned primary driven gear I9 are connected by a transmission chain, and the secondary driven gear II12 and the aforementioned primary driven gear II10 are connected by a transmission chain.

[0059] The working circuits of the motor and electromagnet are switched on and off under the control of the controller.

[0060] Furthermore, a four-stage driven gear I17 is connected to the feed pipe of the drum 5 inside the additive storage tank 4 via a connector, which also includes a limiting groove and an electromagnet. An electromagnet is embedded in the feed pipe of the drum 5, and an annular limiting groove is provided on the outer wall of the feed pipe to limit the position of the four-stage driven gear I17, which is located within the limiting groove. By controlling whether the electromagnet is working, the rigid or rotatable connection between the four-stage driven gear I17 and the feed pipe of the drum 5 is determined.

[0061] Within the reactant storage tank 3, the feed pipe of the rotating drum 5 is connected to a four-stage driven gear II18 via a connector, which includes a limiting groove and an electromagnet. An electromagnet is embedded in the feed pipe of the rotating drum 5, and an annular limiting groove is provided on the outer wall of the feed pipe to restrict the position of the four-stage driven gear II18, which is located within the limiting groove. By controlling whether the electromagnet is activated, the rigid or rotatable connection between the four-stage driven gear II18 and the feed pipe of the rotating drum 5 is determined.

[0062] It is worth emphasizing that in this embodiment, the number of teeth of the fourth-stage driven gear I17 is greater than the number of teeth of the fourth-stage driven gear II18; so that when the drum 5 in the reactant storage tank 3 and the drum 5 in the additive storage tank 4 are driven to work simultaneously by the rotation of the third-stage driven gear 16, the drum 5 in the reactant storage tank works at high speed, while the drum 5 in the additive storage tank 4 works at low speed.

[0063] Several fourth-stage driven gears and a third-stage transmission gear 8 located at the same height plane are connected by a transmission chain. A transmission shaft is rotatably connected between the reaction tank 1 and the mixing tank 6 via a bracket, and the aforementioned third-stage driven gear 16, which rotates with the transmission shaft, is sleeved on the transmission shaft.

[0064] The upper and lower parts of the drive shaft are equipped with driven bevel gear I and driving bevel gear II15.

[0065] The other ends of the first impeller 2 and the second impeller 7 are respectively equipped with a drive bevel gear I14 and a drive bevel gear II15 via a connecting member. The connecting member also includes a limiting groove and an electromagnet. An electromagnet is embedded in the other end of the first impeller 2 and the second impeller 7. The drive bevel gear I14 and the drive bevel gear II15 are located within the limiting grooves of the first impeller 2 and the second impeller 7, respectively. The conduction of the electromagnet controls the connection state between the drive bevel gear I14 and the drive bevel gear II15 and the first impeller 2 and the second impeller 7.

[0066] The mixing box 6 has a discharge port at the bottom of the side wall, and a discharge valve is provided at the discharge port.

[0067] The production method of defoamer on an integrated vertical defoamer production line includes the following processes:

[0068] (1) Add the reaction raw materials into the reaction tank 1 and add the auxiliary agent into the rotating drum 5 of the auxiliary agent storage tank 4;

[0069] (2) At this time, the electromagnets at both ends of the first stirring paddle 2 are working, the electromagnets at both ends of the second stirring paddle 7 are not working, and the electromagnets set on the feed pipe of the drum 5 inside the anti-additive storage tank 4 are working.

[0070] The motor drives the first stirring paddle 2 to rotate at a high speed to carry out the synthesis reaction; the driving bevel gear I14 meshes with the driven bevel gear I, the transmission shaft rotates, and thus the third-stage transmission gear 8 rotates; at this time, it drives the drum 5 inside the additive storage tank 4 to work; thus, while carrying out the synthesis reaction, the operation of the first stirring paddle 2 drives the additive storage tank 4 to perform solid-liquid separation, separating impurities in the additives. When the drum 5 has worked for a set time, the controller controls the electromagnet at the other end of the first stirring paddle 2 to stop working; the electromagnet on the feed pipe of the drum 5 inside the additive storage tank 4 stops working; at this time, the additive storage tank 4 stops the filtration operation;

[0071] (3) When the synthesis reaction is completed, the discharge valve in the reaction tank 1 is opened, and after the reactants enter the drum 5 of the reactant storage tank 3, the discharge valve in the reaction tank 1 is closed. At this time, the electromagnets at both ends of the first stirring paddle 2 are not working, the electromagnets at both ends of the second stirring paddle 7 are working, and the electromagnets set on the feed pipe of the drum 5 in the auxiliary agent storage tank 4 and the reactant storage tank 3 are working. The connecting metering valves between the reactant storage tank 3, the auxiliary storage tank and the mixing tank 6 are all opened. The motor works, drives the second stirring paddle 7 to rotate, thereby driving the three-stage driven gear 16 on the transmission shaft to rotate, driving the drum 5 in the reactant storage tank 3 to work at high speed for centrifugal discharge, and the auxiliary agent storage tank 4 to work at low speed for discharge.

[0072] (4) The second stirring paddle 7 continues to rotate, and the reactant storage tank 3 and the auxiliary agent storage tank 4 continuously discharge raw materials into the mixing tank 6. The stirring paddle in the mixing tank 6 continues to work, which makes the mixing effect better. After the reactant storage tank 3 and the auxiliary agent storage tank 4 have finished discharging, the electromagnet at the other end of the second stirring paddle 7 stops working, the electromagnet on the feed pipe of the drum 5 of the reactant storage tank 3 and the auxiliary agent storage tank 4 also stops working, and the connecting metering valve between the reactant storage tank 3, the auxiliary agent storage tank and the mixing tank 6 is closed.

[0073] (5) After mixing is completed in mixing box 6, the metering valve of mixing box 6 opens to discharge material.

[0074] In this embodiment, the additive storage tank 4 adopts the traditional working mode of stopping the drum 5 for a period of time before rotating it at low speed to discharge the material. The advantage of this mode is that stopping the drum 5 for a period of time before discharging the material can effectively avoid stirring the sedimentation layer, resulting in better separation. The reactant storage tank 3, on the other hand, adopts a high-speed centrifugal discharge mode. The reason for using different discharge modes is that while the additive storage tank 4 is discharging the material, the reactant storage tank 3 is also undergoing a centrifugal separation and discharge process, thereby saving the time spent waiting for the reactant storage tank 3 to centrifuge separately, and saving overall production time.

[0075] Furthermore, the reactant storage tank 3 can be designed as at least two, which allows it to be used in situations where the amount of reactants is relatively large, and at the same time, at least two reactant storage tanks 3 can also be used in application scenarios that require the synthesis of multiple reactants.

[0076] The present invention can be well implemented according to the above embodiments. It is worth noting that, based on the above structural design, even if some non-substantial modifications or refinements are made to the present invention to solve the same technical problem, the essence of the technical solution adopted is still the same as that of the present invention, and therefore it should also be within the protection scope of the present invention.
