Description

Technical Field

[0001] This application relates to the field of sand and gravel testing technology, and in particular to a mixing tank device for detecting the mud content of sand and gravel. Background Technology

[0002] As a core aggregate in building materials such as concrete and mortar, the mud content of sand and gravel is one of the key indicators for measuring quality. Excessive mud content significantly reduces the strength and durability of concrete. Therefore, accurately detecting the mud content in sand and gravel is crucial for project quality control. In traditional testing procedures, sand and gravel samples are mixed with water and soaked, followed by stirring and washing to remove the mud. The purpose of the stirring step is to break the adhesion between the mud and the sand / gravel surface through mechanical force, allowing the mud to be fully dispersed in the water for subsequent separation.

[0003] Traditional mixing tanks generally employ a rigid design where a constant-speed motor directly connects the mixing shaft to the fixed-volume tank. This design is difficult to adapt to different material characteristics. Dry sand requires high-shear dispersion, while wet mortar requires low-speed dispersion to prevent dust and meet process requirements. Dry sand tends to settle and accumulate at a fixed low speed, while wet mortar is prone to aggregate breakage due to excessive shear at a fixed high speed. The lifting structure often relies on a single linear guide rail and a simple slider design, lacking planar constraints. The slider slides only along a single guide rail, making it susceptible to lateral swaying due to material weight or vibration. This can cause misalignment when the mixing mechanism connects to the storage tank, severely affecting the mixing effect and equipment lifespan. Utility Model Content

[0004] This application is made in view of the above-mentioned problems, and its object is to provide a mixing tank device for detecting the mud content of sand and gravel, so as to solve the problems mentioned in the background art. To achieve the above objectives, this utility model provides the following technical solution: a mixing tank device for detecting the mud content of sand and gravel, comprising a longitudinal support, a servo motor, a back guide plate, a drive gear, a driven gear, and a discharge valve. Two sets of transverse supports are symmetrically arranged on the outer bottom of the longitudinal support. The tops of the transverse supports are rigidly connected to the bottom of the storage tank via a supporting structure. Multiple sets of sealing rings are annularly nested on the outer side of the storage tank along its circumference. A mixing mechanism is integrated on the top of the storage tank, driven by a servo motor. The output end of the servo motor is fixedly connected to the drive gear. The tooth surfaces of the driving gear and the driven gear mesh precisely, thereby driving the drive shaft to rotate. The rotation speed of the drive shaft is controlled by the gear meshing transmission ratio. A lifting mechanism is provided on one side of the back guide plate. The lifting mechanism drives the slider to slide vertically along the guide rail through a linear guide rail provided on one side. The slider is rigidly connected to the support base, thereby driving the support base and the mixing mechanism connected to it to descend precisely in the vertical direction, ultimately achieving the separation of the drive shaft from the storage tank. A filling flange is symmetrically provided on one side of the storage tank. The bottom of the storage tank is connected to the output end of the discharge valve through a threaded sealing connection.

[0005] Furthermore, the mixing mechanism includes stirring blades, a drive shaft, a servo motor, a support base, a drive gear, and a driven gear. The stirring blades are arranged in a ring around the outside of the drive shaft. The drive shaft is keyed to the top of the drive shaft, and the drive gear is meshed with one side of the driven gear. The servo motor is mounted on the top of the support base. The drive shaft is tightly connected to the inner ring of a pre-installed bearing in the support base via its outer circumferential surface using an interference fit. The drive gear and the driven gear are positioned directly above the support base.

[0006] Furthermore, the output end of the servo motor is rigidly connected to the drive gear coaxially via a high-precision coupling, and the drive gear meshes with a driven gear on one side.

[0007] Furthermore, the other end of the drive shaft extends axially and is fixedly assembled with multiple sets of stirring blades via a spline structure.

[0008] Furthermore, the lifting mechanism includes a slider, a back guide plate, a linear guide rail, a servo cylinder, and an injection pipe. A servo cylinder is connected to one side of the longitudinal support. The slider is symmetrically arranged on the back of the support base. A linear guide rail is connected to the outer side of the slider. The back of the back guide plate is bolted to the outer side of the longitudinal support. The back of the linear guide rail is connected to the outer side of the longitudinal support. A servo cylinder is connected to the bottom end of the longitudinal support. An injection pipe is connected through the top end of the support base.

[0009] Furthermore, the back guide plate is connected to the outside of the slider via linear guides symmetrically arranged on one side.

[0010] Furthermore, a servo cylinder is rigidly fixed to one side of the longitudinal support via a mounting base, and the output end of the servo cylinder is perpendicularly connected to the bottom end of the support base via a flange or ball joint structure.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This application allows for easy and thorough cleaning of the inner wall of the tank and the mixing blades themselves when the mixing blades are raised outside the tank, avoiding the problem of difficult internal cleaning of fixed mixing devices. This is especially important for materials that are easy to solidify, sticky, or have a risk of cross-contamination. The linear guide rail and slider provide a robust and rigid guide for the lifting of the support base and the entire mixing mechanism, effectively resisting the radial and tangential forces generated during mixing, preventing the drive shaft from swaying or vibrating at high speed, and ensuring smooth operation and bearing life.

[0012] 2. The final output speed of the drive shaft can be precisely controlled by the gear transmission ratio to achieve constant torque transmission. Combined with the excellent speed regulation performance of the servo motor itself, the stirring speed can be controlled with high precision and stepless speed variation to adapt to the specific process requirements of stirring speed for materials with different viscosities and formulations. This greatly simplifies the cleaning and maintenance process, shortens equipment downtime, and ensures the stability and service life of the equipment under long-term high-load operation.

[0021] Terminology explanation: such as Figures 1 to 5As shown, a mixing tank device for detecting the mud content of sand and gravel includes a longitudinal support 1, a servo motor 8, a back guide plate 12, a drive gear 15, a driven gear 16, and a discharge valve 19. Two sets of transverse supports 2 are symmetrically arranged on the outer bottom of the longitudinal support 1. The tops of the transverse supports 2 are rigidly connected to the bottom of the storage tank 3 via a supporting structure. Multiple sets of sealing rings 4 are nested in a ring along the circumferential direction on the outer side of the storage tank 3. A mixing mechanism 5 is integrated on the top of the storage tank 3. The mixing mechanism 5 is driven by the servo motor 8, and the output end of the servo motor 8 is fixedly connected to the drive gear 15. The drive gear 15 and the driven gear... The teeth on one side of the 16 mesh precisely, thereby driving the drive shaft 7 to rotate. The rotation speed of the drive shaft 7 is controlled by the gear meshing transmission ratio. A lifting mechanism 10 is provided on one side of the back guide plate 12. The lifting mechanism 10 drives the slider 11 to slide vertically along the guide rail through the linear guide rail 13 provided on one side. The slider 11 is rigidly connected to the support base 9, thereby driving the support base 9 and the mixing mechanism 5 connected to it to descend precisely in the vertical direction, and finally realizing the separation of the drive shaft 7 from the storage tank 3. A filling flange 18 is symmetrically provided on one side of the storage tank 3. The bottom end of the storage tank 3 is connected to the output end of the discharge valve 19 through a threaded sealing connection.

[0022] The mixing mechanism 5 includes stirring blades 6, a drive shaft 7, a servo motor 8, a support base 9, a drive gear 15, and a driven gear 16. The stirring blades 6 are arranged in a ring around the outside of the drive shaft 7. The driven gear 16 is keyed to the top of the drive shaft 7, and the drive gear 15 is meshed with one side of the driven gear 16. The servo motor 8 is mounted on the top of the support base 9. The drive shaft 7 is tightly connected to the inner ring of a pre-installed bearing in the support base 9 via an interference fit through its outer circumferential surface. The drive gear 15 and the driven gear 16 are positioned directly above the support base 9. The output end of the servo motor 8 is rigidly connected to the drive gear 15 coaxially via a high-precision coupling. The drive gear 15 is meshed with the driven gear 16 on one side. The other end of the drive shaft 7 extends axially and is fixedly assembled with multiple sets of stirring blades 6 via a spline structure. The specific operation is as follows: the servo motor 8 adjusts the speed through the transmission ratio of the active gear 15 and the driven gear 16, and the servo cylinder 14 adjusts the lifting height of the mixing mechanism 5 through stroke control. It is suitable for different working conditions such as rapid mixing of dry sand and low-speed dispersion of wet mortar. The material storage tank 3 is symmetrically equipped with a material injection flange 18 on one side, and the bottom discharge valve 19 is independently controlled to open and close. It can realize flexible operation of feeding and mixing at the same time or centralized discharge after mixing. It has stronger process adaptability than the traditional single-inlet mixing tank. like Figures 1 to 3As shown, the lifting mechanism 10 includes a slider 11, a back guide plate 12, a linear guide rail 13, a servo cylinder 14, and an injection pipe 17. A servo cylinder 14 is connected to one side of the longitudinal support 1. The slider 11 is symmetrically arranged on the back of the support base 9. The outer side of the slider 11 is connected to the linear guide rail 13. The back of the back guide plate 12 is bolted to the outer side of the longitudinal support 1. The back of the linear guide rail 13 is connected to the outer side of the longitudinal support 1. The bottom end of the longitudinal support 1 is connected to the servo cylinder 14. The top end of the support base 9 is connected through the injection pipe 17. The back guide plate 12 is connected to the outer side of the slider 11 via the symmetrically arranged linear guide rail 13. A servo cylinder 14 is rigidly fixed to one side of the longitudinal support 1 via a mounting base. The output end of the servo cylinder 14 is perpendicularly connected to the bottom end of the support base 9 via a flange or ball joint structure. The specific operation is as follows: Multiple sets of stirring blades 6 are evenly distributed in a ring along the outer side of the drive shaft 7 and are fixedly assembled with the drive shaft 7 through a spline structure to ensure that the blades are subjected to balanced force when rotating. With the forward and reverse switching of the servo motor 8, a composite stirring mode of axial shearing and radial diffusion is formed, which significantly improves the mixing uniformity of sand and gravel of different particle sizes. The back guide plate 12 is connected to the linear guide rail 13 through the slider 11. The linear guide rail 13 is symmetrically arranged in the vertical direction and is used for planar limiting of the back guide plate 12.

[0023] Working principle: After the device is assembled, the storage tank 3 is fixed to the longitudinal support 1 by the horizontal support 2 at the bottom. The outer ring-shaped sealing ring 4 fills the gap between the tank and the support base 9. The servo motor 8 is installed on the support base 9. The support base 9 is connected to the linear guide rail 13 by the slider 11. The back guide plate 12 is fixed to the outside of the longitudinal support 1 by bolts to provide planar guidance for the lifting movement. The discharge valve 19 is connected to the bottom of the storage tank 3 by threaded sealing. When feeding is required, the external feeding pipe is sealed and connected to the filling flange 18 of the storage tank 3. The material enters the tank from the filling flange 18. If mixing is required, liquid can be added through the liquid injection pipe 17 at the top of the support base 9 to premix with the solid material. The servo motor 8 is started, and its output end drives the drive gear 15 to rotate through a high-precision coupling. The drive gear 15 and the driven gear 16 are precisely meshed on the top of the drive shaft 7, transmitting power to the drive shaft 7. The drive shaft 7 is interference-fitted with the inner ring of the bearing in the support seat 9 through the outer circumferential surface. The stirring blades 6 at the other end of the drive shaft 7 are evenly distributed in a ring and rotate with the drive shaft 7 to perform multi-dimensional stirring of the material in the tank. The servo motor 8 changes the rotation speed of the drive shaft 7 by adjusting the meshing transmission ratio of the drive gear 15 and the driven gear 16. To separate the drive shaft 7 from the storage tank 3, the servo cylinder 14 is activated. The servo cylinder 14 is rigidly fixed to the bottom of the longitudinal support 1 via a mounting base, and its output end is vertically connected to the bottom of the support base 9 via a flange or ball joint structure. The servo cylinder 14 extends and retracts to push the support base 9, which slides vertically along the linear guide rail 13 via the slider 11. The back guide plate 12 moves synchronously, constraining the movement trajectory of the support base 9 and ensuring that the mixing mechanism 5 descends precisely in the vertical direction, ultimately achieving the separation of the drive shaft 7 from the storage tank 3. To reconnect, the servo cylinder 14 retracts, pulling the support base 9 upward, and the drive shaft 7 is reinserted into the storage tank 3, preparing for the next mixing cycle. After mixing is completed, the discharge valve 19 is opened by the operator, and the mixed material in the storage tank 3 is discharged from the discharge valve 19. The discharge speed can be adjusted by the opening of the discharge valve 19. After discharge is completed, the discharge valve 19 is closed, and the storage tank 3 returns to a sealed state, ready for the next round of feeding.
