Description

Technical Field

[0001] This utility model relates to the field of metering and mixing technology, specifically a metering and mixing device for red-based KD processing. Background Technology

[0002] Red-based KD (chemical name: 3-amino-4-methoxybenzoyl aniline) is an important organic pigment intermediate, CAS number 120-35-4. It is a white to off-white powder with a purity generally exceeding 98%. Its main applications include cotton fabric dyeing, printing, and the continuous synthesis process of Pigment Red 146. Furthermore, a search revealed a powder raw material quantitative mixing device disclosed in Chinese patent CN221808486U, relating to the field of powder mixing technology. The device includes a mixer body, with a feeding mechanism and a baffle mechanism within its internal cavity, a drive mechanism within the internal cavity, a transmission mechanism on the feeding mechanism, and a scraper mechanism within the feeding mechanism. This invention, by setting up a drive mechanism, a transmission mechanism, and a scraper mechanism, starts a motor. The motor drives the rotating shaft through its output end. The rotating shaft causes the fixed block, carrying the baffle, to rotate around the rotating shaft, causing the baffle to leave the mixing drum and allowing the powder to fall into the receiving box. At the same time, the rotating shaft drives the first gear to rotate, which in turn drives the third gear to rotate, which in turn drives the second gear to rotate. The rotation of the second gear drives the lead screw to move the circular scraper downward. The circular scraper scrapes the powder remaining in the mixing drum, allowing the powder to fall into the receiving box. This scraper mechanism ensures that there is no residual powder in the mixing drum.

[0003] However, in actual use, the top surface of the circular scraper is horizontal, which may cause a certain amount of powder material to accumulate on its top surface. This situation will directly lead to errors in subsequent measurement and testing. Utility Model Content

[0004] To address the problem of errors that easily occur in existing metering and mixing devices, this invention provides a metering and mixing device for red-based KD processing.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A metering and mixing device for red-based KD processing includes a tank. The top surface of the tank is provided with a top cover. A retainer is installed at the center of the bottom surface of the top cover. A vertical shaft is rotatably connected to the bottom surface of the retainer. Several horizontal bars are equidistantly installed on the outer wall of the vertical shaft. One end of each of the two sets of horizontal bars is provided with a wall scraping assembly. A triangular scraper is connected between the wall scraping assembly and the vertical shaft. One side of the triangular scraper and the wall scraping assembly are respectively in contact with the inner wall of the tank. A motor is installed on the top surface of the top cover. The output end of the motor is connected to the top end of the vertical shaft.

[0007] Furthermore, the scraping assembly includes a vertical plate, the outer wall of which is fitted with ribs, the edges of which contact the inner wall of the tank.

[0008] The beneficial effects of adopting the above-mentioned further solution are that, compared to flat contact, the ribs, with their edges contacting the inner wall of the tank, exert greater pressure and have a stronger scraping effect, thus more thoroughly stripping away adhering materials. The rib design reduces the friction area with the inner wall of the tank, reducing wear. At the same time, the local disturbance generated by the edge scraping helps to enhance the material mixing effect and improve the stirring quality.

[0009] Furthermore, a half-shaft block is installed on the top surface of the upright plate, and the top surface of the half-shaft block is spaced apart from the bottom surface of the top cover.

[0010] The advantages of adopting the above-mentioned further solution are that it avoids collisions or friction between the scraper assembly and the top cover during rotation, preventing equipment damage. Furthermore, the arc-shaped structure on the top surface of the half-shaft block prevents material accumulation on the top surface of the scraper assembly. This spacing design ensures smooth operation of the scraper assembly while allowing space for material flow in the top area, preventing material accumulation due to component interference and ensuring the continuity of the mixing process.

[0011] Furthermore, the triangular scraper includes a plate body, the outer wall of which has a through hole, and an inner convex ring is installed inside the through hole.

[0012] The beneficial effect of adopting the above-mentioned further solution is that, by setting the through holes, the powdered raw materials can pass smoothly through the plate, thereby realizing the mixing of raw materials. In addition, with the installation and use of the inner convex ring, the powdered raw materials can be effectively prevented from accumulating inside the through holes.

[0013] Furthermore, the bottom of the tank is designed as a cone, with the inner wall of the cone contacting the side of the plate. The cone structure, combined with a triangular scraper, guides the material towards the discharge valve, preventing material residue at the bottom. The beneficial effect of this further design is that the cone structure, combined with the triangular scraper, guides the material towards the discharge valve, preventing material residue at the bottom.

[0014] Furthermore, the bottom end of the cone is connected to a discharge valve, and the bottom end of the vertical shaft is equipped with an auger, the bottom end of which extends into the interior of the discharge valve.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, when the auger rotates, it can forcefully push the material in the cone to the discharge valve, further ensuring that the material is completely discharged and avoiding residue. The spiral structure of the auger, combined with the discharge valve, can achieve quantitative and uniform discharge, meeting the requirements for material output accuracy during processing, while preventing material splashing or blockage during discharge.

[0016] Furthermore, the outer walls of the tank are connected to feed hoppers on both sides, each feed hopper including a hopper body, a hopper cover hinged to the top side of the hopper body, and a handrail installed on the top surface of the hopper cover.

[0017] The beneficial effects of adopting the above-mentioned further solutions are that the hopper cover can prevent materials from spilling or dust from flying during the feeding process, keeping the working environment clean; the handle makes it easy for operators to open or close the hopper cover, improving the convenience of operation.

[0018] Furthermore, a support base is welded to the bottom of the tank, and a pressure sensor is embedded in the bottom surface of the support base.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the pressure sensor on the bottom of the support can monitor the weight of the material in the tank in real time, providing data support for metering and mixing, and ensuring that the weight of the raw materials mixed each time meets the process requirements.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This metering and mixing device for red-based KD processing utilizes a vertical shaft, horizontal bar, wall scraper assembly, triangular scraper, and motor in tandem. This allows the device to maintain a balanced mixing of raw materials while minimizing metering errors caused by material accumulation. The tank and top cover form a closed mixing space. The motor drives the vertical shaft to rotate, causing the horizontal bar, wall scraper assembly, and triangular scraper to rotate synchronously, achieving efficient stirring and mixing of the red-based KD raw materials. The wall scraper assembly and triangular scraper adhere to the inner wall of the tank, effectively removing material adhering to the tank and preventing material residue from causing mixing ratio deviations. Simultaneously, it prevents material accumulation in hard-to-stir corners, improving metering accuracy and ensuring uniform mixing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 This utility model provides a technical solution: a metering and mixing device for processing red-based KD, including a tank 1, a top cover 2 on the top surface of the tank 1, a retainer 7 installed at the center of the bottom surface of the top cover 2, a vertical shaft 8 rotatably connected to the bottom surface of the retainer 7, a plurality of crossbars 9 equidistantly installed on the outer wall of the vertical shaft 8, a wall scraping assembly 10 respectively provided at one end of the two sets of crossbars 9, a triangular scraper 11 connected between the wall scraping assembly 10 and the vertical shaft 8, one side of the triangular scraper 11 and the wall scraping assembly 10 respectively adhering to the inner wall of the tank 1, a motor 3 installed on the top surface of the top cover 2, the output end of the motor 3 being drivenly connected to the top end of the vertical shaft 8, the tank 1 and the top cover 2 forming a closed mixing space, the motor 3 driving the vertical shaft 8 to rotate, driving the crossbars 9, the wall scraping assembly 10 and the triangular scraper 11 to rotate synchronously, realizing efficient stirring and mixing of red-based KD raw materials. The wall scraping assembly 10 and the triangular scraper 11 are attached to the inner wall of the tank, which can effectively remove the material adhering to the tank, avoid the raw material residue causing the mixing ratio deviation, and at the same time prevent the raw material from accumulating in dead corners where it cannot be stirred, which helps to improve the accuracy of metering and ensure uniform mixing.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] As one embodiment of this utility model, the wall scraping assembly 10 further includes a vertical plate 1001, and a rib 1003 is installed on the outer wall of the vertical plate 1001. The edges of the rib 1003 contact the inner wall of the tank 1. Compared with planar contact, the rib 1003 has greater pressure and stronger scraping effect when contacting the inner wall of the tank, and can more thoroughly peel off the attached material. The design of the rib 1003 can reduce the friction area with the inner wall of the tank, reduce wear, and at the same time, the local disturbance generated by the edge scraping helps to enhance the material mixing effect and improve the stirring quality.

[0032] In one embodiment of this utility model, a half-shaft block 1002 is further installed on the top surface of the vertical plate 1001. A gap is provided between the top surface of the half-shaft block 1002 and the bottom surface of the top cover 2 to prevent the scraper assembly 10 from colliding or rubbing against the top cover 2 during rotation, thus preventing equipment damage. Furthermore, the arc-shaped structure of the top surface of the half-shaft block 1002 prevents raw material from accumulating on the top surface of the scraper assembly 10. This gap design ensures smooth operation of the scraper assembly 10 while providing space for material flow in the top area, preventing material accumulation due to component interference and ensuring the continuity of the mixing process.

[0033] As an embodiment of this utility model, the triangular scraper 11 further includes a plate body 1101. The outer wall of the plate body 1101 is provided with a through hole 1102. An inner convex ring 1103 is installed inside the through hole 1102. By setting the through hole 1102, the powdered raw material can pass smoothly through the plate body 1101, thereby realizing the mixing of the raw material. In conjunction with the installation and use of the inner convex ring 1103, the powdered raw material can be effectively prevented from accumulating inside the through hole 1102.

[0034] As an embodiment of this utility model, the bottom end of the tank body 1 is further provided as a cone, and the inner wall of the cone is in contact with the side of the plate body 1101. The cone structure, together with the triangular scraper 11, can guide the material to concentrate towards the discharge valve 5 to avoid material residue at the bottom.

[0035] In one embodiment of this utility model, the bottom end of the cone is connected to a discharge valve 5, and the bottom end of the vertical shaft 8 is equipped with an auger 12. The bottom end of the auger 12 extends into the interior of the discharge valve 5. When the auger 12 rotates, it can force the material in the cone to the discharge valve 5, further ensuring that the material is completely discharged and avoiding residue. The spiral structure of the auger 12, in conjunction with the discharge valve 5, can achieve quantitative and uniform discharge, meeting the requirements for material output accuracy during processing, while preventing material splashing or blockage during discharge.

[0036] In one embodiment of this utility model, the outer walls of the tank body 1 are further connected to feed hoppers 4 on both sides. Each feed hopper 4 includes a hopper body 401, and a hopper cover 402 is hinged to the top side of the hopper body 401. A handle 403 is installed on the top surface of the hopper cover 402. The hopper cover 402 prevents materials from spilling or dust from flying during the feeding process, maintaining a clean working environment. The handle 403 facilitates the opening and closing of the hopper cover 402 by the operator, improving operational convenience. In another embodiment of this utility model, a support base 6 is welded to the bottom of the tank body 1. A pressure sensor is embedded in the bottom surface of the support base 6. The pressure sensor on the bottom surface of the support base 6 can monitor the weight of the material inside the tank in real time, providing data support for metering and mixing, ensuring that the weight of the raw materials mixed each time meets the process requirements.

[0037] Specifically, the working principle of this red-based KD processing metering and mixing device is as follows: During use, the material enters the tank 1 through the hoppers 401 on both sides of the tank 1, with the hopper covers 402 closed to prevent spillage. The pressure sensor on the support base 6 at the bottom of the tank 1 monitors the weight of the material in real time, providing data for accurate metering. Subsequently, the motor 3 on the top surface of the top cover 2 starts, driving the vertical shaft 8 to rotate, which in turn drives the crossbar 9, the wall scraping assembly 10, and the triangular scraper 11 to rotate synchronously. The ribs 1003 of the wall scraping assembly 10 scrape the inner wall of the tank with their edges, peeling off the attached material with greater pressure, while the edge disturbance enhances the mixing effect; on the plate 1101 of the triangular scraper 11, the through holes 1102 and the inner convex rings 1103 allow the powder raw materials to pass through smoothly for stirring, while preventing the raw materials from accumulating. The cone at the bottom of the tank 1 works with the triangular scraper 11 to guide the material toward the discharge valve 5. When the auger 12 at the bottom of the vertical shaft 8 rotates, it pushes the material in the cone to the discharge valve 5 through the spiral, so as to achieve quantitative and uniform discharge. The whole process ensures high precision and high efficiency of mixing red-based KD raw materials through the coordinated operation of multiple components such as stirring, scraping, metering and discharge.
