Description

Technical Field

[0001] The present invention relates to the technical field of fine chemical equipment, and specifically relates to a compound thickener mixing device with production ingredient addition amount distribution adjustment. Background Technique

[0002] In the industrial production field of compound thickeners, the performance of the mixing device plays a decisive role in product quality and production efficiency. At present, there are many technical bottlenecks in traditional compound thickener mixing devices that need to be broken through urgently.

[0003] In terms of the control of ingredient addition amount in existing mixing devices, there is generally a lack of precise quantitative adjustment mechanism. Most use extensive manual measurement or simple mechanical control for feeding, making it difficult to independently and precisely control the addition amounts of various raw materials such as solid and liquid, and unable to meet the strict ratio requirements of each component in the complex formula of compound thickeners, resulting in large fluctuations in product quality.

[0004] In terms of the mixing effect, most devices adopt a single-stage mixing mode. For the raw materials of compound thickeners with solid-liquid mixing, it is difficult to achieve sufficient and uniform mixing. The design of the mixing components is unreasonable, and dead corners are easily formed during the mixing process. Some areas are not mixed sufficiently, while some areas are over-mixed, which not only affects the stability of product performance, but also increases energy consumption and production time costs. In addition, the structural design of traditional mixing devices is not conducive to the complete discharge of materials. The shape matching between the inner wall of the mixing chamber and the mixing components is not good, and the problem of material residue is prominent. This not only causes waste of raw materials, but also easily leads to cross-contamination. Especially in industries with extremely high hygiene standards such as food and medicine, frequent manual cleaning operations reduce production efficiency, increase labor costs and cleaning difficulties.

[0005] Therefore, a compound thickener mixing device with production ingredient addition amount distribution adjustment is proposed to achieve precise distribution adjustment of production ingredient addition amounts, efficient mixing, while reducing material residue and facilitating cleaning and maintenance, meeting the high-precision and high-hygiene requirements of industrial large-scale production.

[0025] Please refer to Figures 1 to 9 , the present invention provides a compound thickener mixing device with adjustment of the addition amount distribution of production ingredients. The mixing device uses the housing 10 as the main support structure. The housing 10 has a vertical cavity structure, and a bracket 11 is fixedly installed at its bottom. The bracket 11 adopts four vertically arranged support legs, which are fixedly connected to the bottom of the housing 10 by welding or bolt connection, and is used to stably support the device on the ground or workbench surface. Inside the housing 10, a first fixing plate 15, a second fixing plate 16 and a third fixing plate 17 are fixedly installed in sequence from top to bottom along the vertical direction. The three fixing plates are all horizontally arranged circular plates, and are fixedly connected to the inner wall of the housing 10 through an annular bracket to form a layered support structure for installing each mixing component and driving component.

[0026] There are two material distribution hoppers 12 symmetrically arranged at the top of the outer shell 10. The material distribution hopper 12 is an inverted funnel-shaped structure, and its interior is divided into four independent storage compartments by a cross-shaped partition. Each storage compartment can store one kind of raw material separately. A single material distribution hopper 12 can accommodate up to four kinds of raw materials at most. The two material distribution hoppers 12 can realize the classified storage of solid raw materials and liquid raw materials (for example, the left material distribution hopper stores solid raw materials and the right one stores liquid raw materials). The bottom outlet of the material distribution hopper 12 is fixedly connected to the material control valve 13. The material control valve 13 is a rectangular cavity structure, and material control plates 14 are respectively installed on both sides inside it. The material control plate 14 is a rectangular plate body, one end of which is movably connected to the inner wall of the material control valve 13 through a rotating shaft, and the other end extends to the outside of the material control valve 13 and is connected to the driving mechanism. The driving mechanism includes eight motors arranged in the first fixing plate 15. The eight motors are divided into two groups, and each group of four motors corresponds to the four storage compartments of one material distribution hopper 12 respectively. Each motor is connected to the rotating shaft of the corresponding material control plate 14 through a transmission shaft. By driving the material control plate 14 to rotate around the rotating shaft by the motor, the opening degree of the discharge port of each storage compartment of the material distribution hopper 12 is adjusted, so as to accurately control the feeding amount of each raw material. Before raw materials are put in, the solid raw materials and liquid raw materials are respectively poured into the corresponding storage compartments through the top openings of the material distribution hoppers 12. The cross-shaped partition ensures that different raw materials do not mix with each other. During installation, it is necessary to ensure that the material distribution hopper 12 is hermetically connected to the top of the outer shell 10 to prevent raw material leakage. The material control valve 13 is fixed to the bottom of the material distribution hopper 12 by bolts, and the material control plate 14 and the transmission shaft of the motor are rigidly connected by a coupling to ensure the stability of power transmission. During debugging, the rotation angle of each motor is set through the control system, the corresponding relationship between the opening degree of the material control plate 14 and the feeding amount is tested, and an accurate control model is established.

[0027] The first mixing component includes two symmetrically arranged first mixing bins 20, both of which are fixedly installed on the upper surface of the first fixing plate 15 and are distributed symmetrically left and right. Each first mixing bin 20 is integrally formed by an upper square shell and a lower spherical shell. The square shell facilitates the rapid introduction and preliminary stirring of raw materials, while the spherical shell is conducive to reducing material residue and improving the mixing effect. A material guiding pipe 22 is fixedly connected below the first mixing bin 20. The upper part of the material guiding pipe 22 is a cylindrical tube, which is coaxially connected to the bottom outlet of the first mixing bin 20. The lower part is an inclined conical tube, and its outlet end is inclined towards the second mixing component, facilitating the smooth flow of raw materials into the second mixing bin 30. A first blanking plate 21 is movably installed between the material guiding pipe 22 and the first mixing bin 20. The first blanking plate 21 is a circular plate body, which is movably connected to the inner wall of the material guiding pipe 22 through a rotating shaft. One end of its rotating shaft extends outside the outer shell 10 and is connected to the motor built in the second fixing plate 16. By driving the first blanking plate 21 to rotate through the motor, the opening or closing of the material guiding pipe 22 is realized. A first rotating shaft 23 is vertically arranged at the central position inside the first mixing bin 20. The top end of the first rotating shaft 23 passes through the first fixing plate 15 and extends into the control valve 13, and is connected to the output shaft of the first motor 26 fixedly installed in the control valve 13 through a coupling. A first stirring plate 25 is fixedly installed at the bottom of the first rotating shaft 23 and is symmetrically distributed around the center. The first stirring plate 25 is a straight inclined plate, and the plane of the plate forms an angle of 30° - 45° with the axis of the first rotating shaft 23. The edge is processed into an arc adapted to the inner wall of the lower spherical shell of the first mixing bin 20 to ensure that the stirring plate can be close to the inner wall of the spherical shell when rotating, avoiding material retention. Two rows of first stirring rods 24 are fixedly installed in the middle of the first rotating shaft 23. The two rows of first stirring rods 24 are spaced up and down and arranged staggeredly. Each row has four first stirring rods 24, all of which are symmetrically distributed around the first rotating shaft 23. A spherical entity is fixedly installed on each first stirring rod 24. The spherical entity is made of wear-resistant materials (such as stainless steel or engineering plastics) to enhance the material shearing and mixing effects during the stirring process. When installing the first mixing component, first fix the first mixing bin 20 to the first fixing plate 15 with bolts to ensure its position corresponds to that of the material distributing hopper 12 (for example, the left material distributing hopper corresponds to the left first mixing bin for mixing solid raw materials; the right material distributing hopper corresponds to the right first mixing bin for mixing liquid raw materials). The material guiding pipe 22 and the bottom of the first mixing bin 20 are connected by a flange to ensure the sealing performance. The first rotating shaft 23 passes through the central hole of the first fixing plate 15 and is rotationally supported through a bearing seat, and the bearing seat is fixed on the first fixing plate 15. The first motor 26 is fixed at the central position of the inner wall of the control valve 13 through a bracket, and its output shaft is connected to the top end of the first rotating shaft 23 through an elastic coupling to compensate for the installation error.When performing preliminary mixing, first, the control system closes the first blanking plates 21 below the two first mixing bins 20 (that is, drives the motor in the second fixing plate 16 to rotate the first blanking plate 21 to a position perpendicular to the axis of the material guiding pipe 22 to block the blanking channel). Subsequently, the first motor 26 is started, and the first motor 26 drives the first rotating shaft 23 to rotate at a speed of 100 - 300 r / min. At the same time, the blanking amount of each storage compartment is adjusted through the blanking plate 14 of the material control valve 13, so that the solid raw material and the liquid raw material respectively fall into the corresponding first mixing bins 20. In the first mixing bin 20, the first rotating shaft 23 drives the first stirring plate 25 and the first stirring rod 24 to rotate synchronously: the first stirring plate 25 at the bottom turns over and stirs the raw materials falling into the spherical shell, and the axial thrust generated by the inclined plate structure makes the materials move upward; the two rows of first stirring rods 24 in the upper part fully mix the materials through the stirring and shearing of the spherical entity. Since the two rows of first stirring rods 24 are staggered, cross-flow of the upper and lower layer materials can be formed to enhance the mixing uniformity. The preliminary mixing time can be set to 5 - 15 minutes according to the characteristics of the raw materials to ensure that the solid raw materials or the liquid raw materials reach a preliminary uniform mixing state.

[0028] The second mixing component includes a second mixing chamber 30 fixedly installed on the lower surface of the second fixed plate 16. The second mixing chamber 30 is a spherical shell structure, and three through holes are provided in its upper part: the middle through hole is in the vertical direction for installing the second rotating shaft 34; the two side through holes are in the horizontal direction and are respectively butted with the outlet ends of the two guide pipes 22 to realize the raw material transportation between the first mixing chamber 20 and the second mixing chamber 30. The second rotating shaft 34 is vertically arranged at the central position of the second mixing chamber 30. Its top passes through the second fixed plate 16 and is connected to the output shaft of the second motor 33 fixedly installed on the upper surface of the second fixed plate 16. The second motor 33 is located between the two guide pipes 22 and is fixed to the second fixed plate 16 through a bracket. The lower part of the second rotating shaft 34 passes through the central hole of the third fixed plate 17 and is rotationally supported through a bearing seat, and the bearing seat is fixed to the third fixed plate 17. The second rotating shaft 34 is successively provided with a blanking scraper 35, a second stirring plate 36, a mixing plate 37, and a disturbing plate 39 from top to bottom: the blanking scraper 35 is located at the upper part of the second rotating shaft 34 and is a row of obliquely-arranged arc plates symmetrically distributed around the center. The plate surface of each scraper forms an angle of 45° - 60° with the axis of the second rotating shaft 34, and the edge is processed into an arc shape adapted to the inner wall of the upper spherical shell of the second mixing chamber 30. When the second rotating shaft 34 rotates, the blanking scraper 35 can scrape off the raw materials attached to the upper part of the spherical shell to avoid residue; the second stirring plate 36 is located at the lower part of the second rotating shaft 34 and is a row of straight inclined plates symmetrically distributed around the center. The plate surface forms an angle of 30° - 45° with the axis of the second rotating shaft 34, and the edge arc is adapted to the inner wall of the lower spherical shell of the second mixing chamber 30 for turning and stirring the bottom materials; the mixing plate 37 is located in the middle of the second rotating shaft 34 and is provided with four fin-shaped plate bodies symmetrically distributed around the center. The mixing plate 37 is fixedly connected to the second rotating shaft 34 through a connecting rod. A mixing rod 38 is fixedly installed in the middle of the connecting rod. A spherical entity (with the same structure as the spherical entity of the first stirring rod 24) is fixed on the mixing rod 38. The edge of the mixing plate 37 is an arc shape adapted to the inner wall of the middle spherical shell of the second mixing chamber 30 for stirring and shearing the middle materials; the disturbing plate 39 is located at the position between adjacent mixing rods 38 and is fixedly connected to the second rotating shaft 34 through a connecting rod, and is a vertically symmetric conical structure symmetrically distributed around the center. When the second rotating shaft 34 rotates, the disturbing plate 39 can break up the material lumps formed during the mixing process to promote further mixing. The bottom outlet of the second mixing chamber 30 is fixedly connected to a blanking pipe 32. The blanking pipe 32 is a cylindrical tube, and its inlet end is aligned with the lowest point of the bottom spherical shell of the second mixing chamber 30 to ensure that the materials can be completely discharged. A second blanking plate 31 is arranged between the blanking pipe 32 and the second mixing chamber 30. The structure of the second blanking plate 31 is the same as that of the first blanking plate 21 and is movably connected to the inner wall of the blanking pipe 32 through a rotating shaft. One end of the rotating shaft is connected to the motor built in the third fixed plate 17, and the opening or closing of the blanking pipe 32 is realized through the drive of the motor.When installing the second mixing component, first fix the second mixing chamber 30 to the lower surface of the second fixing plate 16 by bolts, ensuring that the horizontal through holes on both sides are aligned with the outlet end of the material guiding pipe 22, and achieving detachable connection through flanges or sealing joints for easy later maintenance. The second rotating shaft 34 passes through the middle through hole of the second fixing plate 16, the second mixing chamber 30 and the third fixing plate 17 in sequence, and realizes axial and radial positioning through the bearing seat to ensure the rotation accuracy. The second motor 33 is connected to the top of the second rotating shaft 34 through a rigid coupling to ensure the reliability of power transmission. When the first mixing chamber 20 completes the preliminary mixing, first perform the operation of introducing the liquid raw material: drive the motor in the right second fixing plate 16 through the control system to open the first blanking plate 21 below the right first mixing chamber 20 (i.e., the first mixing chamber where the liquid raw material is located). The liquid raw material flows into the horizontal through hole on the left side of the second mixing chamber 30 through the inclined conical tubular outlet of the material guiding pipe 22 under the action of gravity. At the same time, start the second motor 33, and the second motor 33 drives the second rotating shaft 34 to rotate at a speed of 200 - 400 r / min. The blanking scraper 35 and the mixing plate 37 initially stir the flowing liquid raw material to prevent local accumulation of the liquid raw material in the spherical shell. After the liquid raw material is completely introduced (which can be controlled by the flow sensor or time set in the material guiding pipe 22), close the right first blanking plate 21, and then open the first blanking plate 21 below the left first mixing chamber 20 (the first mixing chamber where the solid raw material is located). The solid raw material flows into the horizontal through hole on the right side of the second mixing chamber 30 through the left material guiding pipe 22. At this time, the second rotating shaft 34 continues to rotate, and the blanking scraper 35 scrapes down the newly flowing solid raw material to make it initially contact with the liquid raw material; the second stirring plate 36 at the bottom turns over the mixed material to make the material move upward from the bottom; the mixing plate 37 and the mixing rod 38 in the middle realize the preliminary mixing of the solid and liquid raw materials through the stirring and shearing of the spherical entity; the disturbing plate 39 breaks up the material lumps formed during the mixing process to avoid mixing dead corners. The secondary mixing process lasts for 10 - 20 minutes. Through the coordinated action of each component on the second rotating shaft 34, multi-angle mixing of the material is achieved: the blanking scraper 35 processes the residual material in the upper part, the second stirring plate 36 processes the material at the bottom, and the mixing plate 37 and the disturbing plate 39 process the material in the middle to form an up-and-down circulating mixing flow field to ensure the mixing uniformity. After the mixing is completed, drive the motor in the third fixing plate 17 to open the second blanking plate 31, and the mixed material is discharged through the blanking pipe 32 under the action of gravity and enters the subsequent process (such as packaging or storage).

[0029] In the motor drive system, the first motor 26 is used to drive the first rotating shaft 23 to achieve preliminary mixing in the first mixing chamber 20. Its rotation speed can be adjusted by a frequency converter to meet the mixing requirements of raw materials with different viscosities; the second motor 33 is used to drive the second rotating shaft 34 to achieve secondary mixing in the second mixing chamber 30. Its rotation speed is also adjusted by a frequency converter and can be linked with the rotation speed of the first motor 26 (for example, the rotation speed is automatically increased when solid raw materials are introduced to enhance the shearing effect); the drive motor of the material control plate 14, the first unloading plate 21 and the second unloading plate 31 are all programmed through the PLC control system to achieve program control, and the unloading amount and unloading sequence can be automatically adjusted according to the preset formula. In terms of sealing and cleaning design, O-rings or polytetrafluoroethylene sealing pads are used between the material distribution hopper 12 and the material control valve 13, and between the material guide pipe 22 and the first mixing bin 20 and the second mixing bin 30 to ensure that the device is in a sealed state during the mixing process to avoid dust or liquid leakage; the spherical shell structure of the first mixing bin 20 and the second mixing bin 30 is convenient for online cleaning (CIP) through a cleaning pipe. After each production is completed, cleaning liquid can be introduced through the material guide pipe 22 and the discharge pipe 32, and the motor can be started to drive the shaft to rotate, so as to realize automatic cleaning inside the shell, reduce manual intervention and improve production efficiency.

[0030] Through the above structural design and operation steps, the precise adjustment of the batching amount is achieved. Through the separation of the storage compartments of the material dividing hopper 12 and the control of the opening degree of the material control plate 14, the independent feeding control of four solid raw materials and four liquid raw materials can be realized, meeting the requirements of precise proportioning of multi-components of compound thickeners; excellent mixing effect is achieved. Two first mixing components are set to preliminarily mix the solid raw materials and liquid raw materials respectively, and then the second mixing component is used to perform secondary mixing on the preliminarily mixed solid raw materials and liquid raw materials. The step-by-step mixing method can significantly improve the mixing uniformity of the raw materials. The square shell at the upper part and the spherical shell at the lower part of the first mixing chamber, in cooperation with the first stirring rod and the first stirring plate, can fully stir and turn over the raw materials. The spherical shell of the second mixing chamber, together with the synergistic effect of the feeding scraper, the second stirring plate, the mixing plate and the disturbing plate, can realize multi-angle and all-round mixing of the raw materials. At the same time, the disturbing plate can break up the mixture, further promoting the mixing of the raw materials and ensuring the mixing effect; the material residue is reduced. The spherical shell at the lower part of the first mixing chamber is adapted to the arc at the edge of the first stirring plate, and the spherical shell of the second mixing chamber is adapted to the arcs at the edges of the feeding scraper, the second stirring plate and the mixing plate. This structural design can effectively reduce the residue of materials on the inner wall of the mixing chamber, facilitating cleaning. Combined with the online cleaning function, the cleaning of the device can be quickly completed, meeting the hygiene requirements of industries such as food and medicine, improving production efficiency, and at the same time ensuring the stability of product quality. Through the organic integration of the component structure and operation steps, the precise control of the batching amount and the efficient mixing of raw materials in the production process of compound thickeners are achieved. It has the advantages of compact structure, convenient operation, excellent mixing effect, etc., and is suitable for large-scale industrial production.

[0031] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
