Description

Technical Field

[0001] This utility model relates to the field of chemical processing technology, and more specifically to an automatic proportioning and mixing device for chemical raw materials. Background Technology

[0002] In the field of chemical production, the mixing of chemical raw materials plays a decisive role in the quality and performance of the final chemical products. From common building materials to high-end precision electronic materials, the manufacturing of various chemical products relies on efficient and precise raw material mixing equipment.

[0003] Current chemical raw material mixing devices mostly adopt traditional stirring methods, which usually involve putting the raw materials into a mixing tank and directly stirring them with stirring components. This stirring method directly stirs a large amount of material at the same time, resulting in insufficient mixing effect of a large amount of material during the stirring process, thus reducing the mixing efficiency. To address this, we propose an automatic proportioning and mixing device for chemical raw materials. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an automatic proportioning and mixing device for chemical raw materials, so as to solve the problem of automatic proportioning and mixing devices for chemical raw materials.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an automatic proportioning and mixing device for chemical raw materials, including a base, a mixing box installed on the base, a guide box provided on the top of the mixing box, the number of guide boxes being at least two sets, a discharge hopper installed at the bottom of the base corresponding to the position of the mixing box, a drive motor installed on the side wall of the mixing box, the output shaft of the drive motor slidingly extending through the corresponding position wall of the mixing box into the interior of the mixing box, a stirring shaft installed on the output shaft of the drive motor, and a premixing component provided on the top inner side of the mixing box. The premixing component is located above the stirring shaft. The premixing component includes a mixing adjustment component, a partition base plate, a partition top plate, a discharge port, a discharge port, and an auxiliary motor. The partition base plate is fixedly installed on the inner side wall of the mixing tank. The partition top plate is disposed on the partition base plate. The auxiliary motor is installed at the bottom center of the partition base plate. The output shaft of the auxiliary motor slides through the corresponding wall surface of the partition base plate and connects with the bottom of the partition top plate. The discharge port is annularly spaced on the partition top plate, and the discharge port is annularly spaced on the partition base plate.

[0006] Preferably, the premixing assembly further includes an auxiliary shaft and a side plate. The auxiliary shaft is disposed at the top center of the partition top plate, and the side plate is arranged in a ring on the side wall of the auxiliary shaft, with the end of the side plate away from the auxiliary shaft mounted on the top wall of the partition top plate.

[0007] Preferably, the mixing adjustment component includes an adjustment spring and an adjustment plate. The adjustment spring is located at the middle position of the auxiliary shaft and divides the auxiliary shaft into two sections. The adjustment plate is located at the middle position of the side plate and divides the side plate into two sections. A reset adjustment component is provided inside the adjustment plate.

[0008] Preferably, the reset adjustment component includes a limiting ball, a locking rod, a retaining sleeve, an adjusting ball, and an auxiliary adjustment spring. The limiting ball is a spherical block and is spaced apart on the inner side of the adjustment plate. The locking rod is fixedly installed on one end of the limiting ball, and the retaining sleeve is fixedly installed on the other end of the limiting ball. The retaining sleeves and locking rods on adjacent sets of limiting balls correspond to each other. The inside of the retaining sleeve is hollow. The adjusting ball is located on the inner side of the retaining sleeve and is a spherical block. The end of the locking rod away from the limiting ball slides through the corresponding position wall of the retaining sleeve and communicates with the adjusting ball. The auxiliary adjustment spring is located on the inner side of the retaining sleeve, and its two ends are respectively connected to the corresponding positions of the limiting ball and the adjusting ball.

[0009] Preferably, the reset adjustment component further includes a side adjustment groove, which is formed on both sides of the sleeve and penetrates the corresponding wall surface of the sleeve and communicates with the inside of the sleeve. The side adjustment groove also penetrates the side wall of the sleeve corresponding to the position of the locking rod, and the width of the side adjustment groove is adapted to the outer diameter of the locking rod.

[0010] Preferably, a limiting ring is fixedly installed on the top of the partition substrate at the position corresponding to the discharge port. The limiting ring is in the shape of a circular block. A limiting ring groove is formed on the bottom of the partition top plate at the position corresponding to the limiting ring. The size of the limiting ring groove is adapted to the size of the limiting ring.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, when the mixture is conveyed to the partition top plate through the guide box, the auxiliary motor drives the partition top plate, the auxiliary shaft on the partition top plate, and the side plate to pre-stir the mixture. At the same time, as the stirring operation proceeds, the discharge port on the partition top plate and the discharge port on the partition base plate will gradually overlap, thereby intermittently conveying the pre-stirred mixture to the stirring shaft. Thus, by using pre-stirring and segmented conveying and stirring, the insufficient mixing effect and reduced mixing efficiency caused by direct stirring through the stirring shaft are greatly avoided.

[0012] 2. In this utility model, when pre-mixing and stirring are performed on the top plate of the partition, the distribution of the mixture on the top plate and the influence of centrifugal force cause the auxiliary shaft and side plate on the top plate of the partition to deform accordingly. The adjusted auxiliary shaft and side plate are adjusted accordingly as the top plate of the partition rotates, so that the mixture on the side with more mixture and the mixture on the side with less mixture can be effectively and evenly mixed, thereby greatly improving the mixing effect of different raw materials and effectively reducing the reduction of mixing effect caused by the differences between the materials when mixing multiple materials.

[0013] 3. In this utility model, the reset adjustment component on the adjustment plate enables the adjustment ball to be guided and adjusted in the sleeve and the side adjustment groove on the sleeve when adjustment is required, so that the adjustment can be adjusted within a specified range. When the operation stops, the auxiliary adjustment spring can be used to effectively reset the component, thereby effectively ensuring the long service life of the mixing adjustment component.

[0016] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0017] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-6 The present invention will be further described below.

[0018] like Figure 1 - Figure 6 As shown, an automatic proportioning and mixing device for chemical raw materials includes a base 1, a mixing box 2 installed on the base 1, a guide box 3 provided on the top of the mixing box 2, and at least two sets of guide boxes 3. The interior of the guide box 3 penetrates the corresponding wall of the mixing box 2 and communicates with the interior of the base 1.

[0019] Furthermore, a weighing module can be installed at the connection point between the feed box 3 and the mixing box 2. The weighing module is a publicly available technology and will not be described in detail here.

[0020] In this implementation scheme, the weighing module can effectively control the transfer of raw materials inside the feed box 3 to the mixing box 2 in appropriate amounts through weight calculation. The calculation method and rules for the raw material weight ratio are adjusted according to the appropriate raw materials.

[0021] Furthermore, a discharge hopper 4 is installed at the bottom of the base 1 corresponding to the position of the mixing box 2. The interior of the discharge hopper 4 penetrates the corresponding wall of the base 1 and the mixing box 2 and communicates with the interior of the mixing box 2. A discharge control valve is provided at the connection between the discharge hopper 4 and the mixing box 2. The discharge control valve is a publicly available technology and will not be described in detail here.

[0022] Furthermore, a drive motor 5 is installed on the side wall of the mixing box 2, and the output shaft of the drive motor 5 slides through the corresponding position of the wall of the mixing box 2 and extends into the interior of the mixing box 2.

[0023] Furthermore, a stirring shaft 6 is mounted on the output shaft of the drive motor 5.

[0024] Furthermore, a premixing component is provided on the inner top of the mixing tank 2, and the premixing component is located above the stirring shaft 6.

[0025] Furthermore, the premixing assembly includes a partition substrate 7, a partition top plate 8, an auxiliary shaft 9, a discharge port 11, a side plate 12, a discharge port 14, and an auxiliary motor 23.

[0026] Furthermore, the partition plate 7 is circular and is fixedly installed on the inner side wall of the mixing box 2. The partition plate 7 is located above the stirring shaft 6. The partition top plate 8 is set on the partition plate 7, and the size of the partition top plate 8 is adapted to the size of the partition plate 7. The auxiliary motor 23 is installed at the bottom middle position of the partition plate 7. The output shaft of the auxiliary motor 23 slides through the corresponding position wall of the partition plate 7 and is connected to the bottom of the partition top plate 8. The auxiliary shaft 9 is set at the top middle position of the partition top plate 8. The side plate 12 is arranged in a ring on the side wall of the auxiliary shaft 9, and the end of the side plate 12 away from the auxiliary shaft 9 is installed on the top wall of the partition top plate 8. The side plate 12 is triangular. The discharge port 11 is opened in a ring at intervals on the partition top plate 8, and the discharge port 14 is opened in a ring at intervals on the partition plate 7.

[0027] In this embodiment, the auxiliary motor 23 drives the partition top plate 8 to rotate, so that the auxiliary shaft 9 and the side plate 12 on the partition top plate 8 stir the mixture on the partition top plate 8. As the partition top plate 8 rotates, the discharge port 11 on the partition top plate 8 and the discharge port 14 on the partition base plate 7 overlap, so that the premixed raw materials are conveyed downward through the overlap of the discharge port 11 and the discharge port 14, so that the premixed mixture is stirred and mixed by the stirring shaft 6.

[0028] Furthermore, a limiting ring 15 is fixedly installed on the top of the partition substrate 7 corresponding to the position of the discharge port 14. The limiting ring 15 is a circular block shape. A limiting ring groove 22 is opened on the bottom of the partition top plate 8 corresponding to the position of the limiting ring 15. The size of the limiting ring groove 22 is adapted to the size of the limiting ring 15.

[0029] In this embodiment, the limiting ring 15 and the limiting ring groove 22 enable the premixed material to be transported only within the area restricted by the limiting ring 15 when the partition top plate 8 is rotating and mixing and the premixed material is being transported downward, thus preventing the premixed material from being transported into the gap between the partition substrate 7 and the partition top plate 8 and causing blockage due to the accumulation of the premixed material.

[0030] Furthermore, the premixing component also includes a mixing regulator.

[0031] Furthermore, the mixing adjustment component includes an adjustment spring 10 and an adjustment plate 13. The adjustment spring 10 is located in the middle of the auxiliary shaft 9 and divides the auxiliary shaft 9 into two sections. The adjustment plate 13 is located in the middle of the side plate 12 and divides the side plate 12 into two sections. The adjustment plate 13 is made of a material that can elastically deform.

[0032] In this embodiment, when the partition top plate 8 rotates, the mixture on the partition top plate 8 is affected by the transmission of the mixture and the centrifugal force of the rotation. The mixture on the partition top plate 8 will squeeze the auxiliary shaft 9 and the side plate 12 on the auxiliary shaft 9. At the same time, the auxiliary shaft 9 and the side plate 12 are affected by the compression of the mixture on both sides, and the deformation is adjusted accordingly. The auxiliary shaft 9 drives the side plate 12 to tilt towards the side with less mixture. The adjusted auxiliary shaft 9 and the side plate 12 are adjusted accordingly with the rotation of the partition top plate 8, so that the mixture on the side with more mixture and the mixture on the side with less mixture can be effectively and evenly mixed, which greatly improves the premixing effect.

[0033] Furthermore, a reset adjustment component is provided inside the adjustment plate 13.

[0034] In this embodiment, the adjustment plate 13 can be effectively adjusted within a limited range by the reset adjustment component, and can be reset and restored without being affected by pressure and centrifugal force.

[0035] Furthermore, the reset adjustment component includes a limiting ball 16, a locking rod 17, a retaining sleeve 18, an adjusting ball 19, an auxiliary adjusting spring 20, and a side adjusting groove 21. The limiting ball 16 is a spherical block, and the limiting balls 16 are spaced apart inside the adjusting plate 13. The locking rod 17 is fixedly installed on one end of the limiting ball 16, and the retaining sleeve 18 is fixedly installed on the other end of the limiting ball 16. The retaining sleeves 18 and locking rods 17 on adjacent sets of limiting balls 16 correspond to each other. The inside of the retaining sleeve 18 is hollow. The adjusting ball 19 is located inside the retaining sleeve 18 and is a spherical block. The locking rod 17... The end away from the limiting ball 16 slides through the corresponding position wall of the sleeve 18 and is connected to the adjusting ball 19. The auxiliary adjusting spring 20 is set on the inner side of the sleeve 18. The two ends of the auxiliary adjusting spring 20 are respectively connected to the corresponding positions of the limiting ball 16 and the adjusting ball 19. The side adjusting groove 21 is opened on the two side walls of the sleeve 18, and the side adjusting groove 21 penetrates the corresponding position wall of the sleeve 18 and is connected to the interior of the sleeve 18. The side adjusting groove 21 also penetrates the side wall of the sleeve 18 corresponding to the position of the locking rod 17. The width of the side adjusting groove 21 is adapted to the outer diameter of the locking rod 17.

[0036] In this embodiment, the adjusting plate 13 is affected by the extrusion of the mixture, centrifugal force, and adjustment of the auxiliary shaft 9. The adjusting plate 13 will adapt and deform according to the adjustment between the two adjacent sets of limiting balls 16 inside the adjusting plate 13. The two adjacent sets of limiting balls 16 can drive the adjusting ball 19 to move inside the sleeve 18 through the locking rod 17, thereby driving the adjusting plate 13 to shrink and adjust. The two adjacent sets of limiting balls 16 can rotate and adjust with the adjusting ball 19 as the base point under the restriction of the side adjustment groove 21 through the locking rod 17, thereby enabling the adjusting plate 13 to adapt and bend the side wall. When the adjusting plate 13 is no longer affected by the pressure of the mixture and centrifugal force, the elasticity and torque of the auxiliary adjusting spring 20 can effectively drive the locking rod 17 to reset and adjust, thereby enabling the adjusting plate 13 to reset.

[0037] Working principle and usage process of this utility model: In use, different raw materials are put into the corresponding feed boxes 3, and the feed boxes 3 are used to transfer the materials into the mixing box 2 in an appropriate proportion. The mixture is then transferred to the partition top plate 8, and the partition top plate 8 is rotated by the auxiliary motor 23. The auxiliary shaft 9, adjusting spring 10, side plate 12 and adjusting plate 13 on the partition top plate 8 are adjusted by the centrifugal force generated by the rotation of the partition top plate 8 and the pressure generated by the extrusion of the mixture. The mixture is then mixed and stirred in an appropriate manner. Under the action of the centrifugal force generated by the rotation and after the discharge port 11 and discharge port 14 overlap, the mixture is transferred to the position of the stirring shaft 6 inside the mixing box 2. The stirring shaft 6 is driven by the drive motor 5 to stir inside the mixing box 2. At the same time, the mixed raw materials are transferred to the designated position through the discharge hopper 4, thus completing the automatic proportioning and mixing of chemical raw materials.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
