Description

Technical Field

[0001] This invention relates to the field of soda ash blending equipment technology, and in particular to a soda ash blending gantry crane. Background Technology

[0002] Pure soda ash is a white crystalline powder that dissolves quickly in water, rapidly forming a uniform alkaline solution. This allows it to work quickly in wool washing and scouring processes, effectively removing impurities such as lanolin and sweat from the wool surface. During wool processing, it effectively adjusts the pH of the washing solution, promoting the emulsification and removal of impurities, without causing excessive corrosion or damage to the wool fibers. This helps maintain the softness and elasticity of the wool. Current production techniques typically involve mixing and preparing it in a tank with a stirring unit.

[0003] For example, Chinese patent application number CN202420272144.1 discloses a soda ash dissolving device, including a barrel body with a water inlet and a feed inlet on the top cover. The barrel body has a horizontally arranged partition dividing it into an upper chamber and a lower chamber. The partition has multiple through holes running vertically. The lower chamber has a liquid outlet on its side wall. The device also includes a stirring unit comprising a motor and a stirring shaft. Upper chamber stirring blades and lower chamber stirring blades are respectively installed on the stirring shaft inside the upper and lower chambers. This reduces the amount of alkali entering the pipeline, prevents blockage, and stabilizes production conditions. However, this dissolving device relies solely on the mechanical stirring of the stirring unit. Soda ash powder and aqueous solution are prone to bottom sedimentation and low concentration at the top. Especially with batches of non-uniform concentration mixing tanks, dead zones often exist at the bottom, preventing sufficient material agitation and resulting in slow dissolution, making it difficult to meet high-precision process requirements. Summary of the Invention

[0004] In view of this, the purpose of this invention is to propose a soda ash mixing gantry to solve the problems of bottom sedimentation and low upper concentration of soda ash powder and aqueous solution that are easily caused by mechanical stirring of the stirring unit alone in the prior art. In particular, there are often dead zones at the bottom of the mixing tank with batches of non-uniform concentrations, and the materials cannot be sufficiently disturbed.

[0005] To achieve the above objectives, the present invention provides a soda ash mixing gantry, comprising a gantry frame, wherein the top of the gantry frame is provided with a transverse preset track and a longitudinal preset track, and a constant temperature chamber is provided below the gantry frame, the lower end of the constant temperature chamber having a cavity structure. The soda ash mixing gantry also includes: Several mixing barrels are evenly distributed inside the constant temperature chamber, and all of the mixing barrels are placed in the working area below the gantry frame; A stirring rod located at the top of the gantry frame; Several rotating air supply cylinders are evenly distributed in the lower cavity of the constant temperature chamber, and the rotating air supply cylinders correspond to the bottom of the mixing barrel; A drive unit for driving the stirring rod to move bidirectionally on the gantry frame; while the stirring rod moves bidirectionally on the gantry frame, it drives the rotating air supply cylinder to rotate intermittently via a transmission unit.

[0006] Furthermore, both the horizontal and vertical preset tracks are arranged in double rows. The horizontal preset track is slidably mounted on the vertical preset track, and the vertical preset track forms a frame-type load-bearing structure through vertical end beams.

[0007] Furthermore, multiple sets of mixing barrels are arranged in a matrix and fixed below the gantry frame, with an opening on the top of each set of mixing barrels to allow the stirring rod to extend into it.

[0008] Furthermore, the barrel body is made of alkali-resistant and corrosion-resistant material, and equal-spaced gaps are reserved between adjacent mixing barrels for heat dissipation and maintenance. The bottom of the barrel body is sealed and connected to the rotating air supply cylinder.

[0009] Furthermore, an axial air passage is opened inside the rotating air supply cylinder, and multiple sets of oblique jet nozzles are evenly distributed on the outer side of the cylinder body. The jet nozzles are inclined relative to the inner wall of the bottom of the mixing barrel.

[0010] Furthermore, the drive unit includes: The system includes a bidirectional sliding motor, a transmission gear set, and a sliding slider. The sliding slider is mounted on the horizontal preset track, and the top of the stirring rod is fixedly installed at the bottom of the sliding slider. The bidirectional sliding motor drives the sliding slider to slide directionally along the horizontal and vertical preset tracks through the transmission gear set.

[0011] Furthermore, the transmission unit includes: The system includes a connecting rod, a transmission rack, and a synchronous gear set. The connecting rod is fixed to the lower end of the transmission gear set near the longitudinal preset track. The transmission rack is located at the end of the connecting rod. The synchronous gear set is coaxially connected to the rotating air supply cylinder and meshes with the transmission rack.

[0012] Furthermore, the axial air passage of the rotary air supply cylinder is externally connected to an adjustable air source pressure regulating valve, which is fixed to the side wall of the gantry frame.

[0013] Furthermore, the stirring rod is a vertically telescopic multi-segment rod structure, and stirring blades can be detachably installed at the bottom end of the stirring rod. The stirring blades are arranged in an obliquely staggered pattern.

[0014] Furthermore, a short turbulence rod is provided between the multiple layers of stirring blades at the bottom end of the stirring rod, and the short turbulence rod extends radially.

[0015] The beneficial effects of this invention are as follows: In use, the driving unit drives the stirring rod to complete the horizontal and vertical bidirectional sliding. While the stirring rod moves, the transmission unit synchronously drives the rotating air supply cylinder to achieve intermittent rotation, realizing the coordinated linkage between the movement of the stirring rod and the rotation of the rotating air supply cylinder. The rotating air supply cylinder and the stirring rod work together to form a dual mixing mode that combines mechanical stirring and bottom airflow disturbance, solving the problems of material deposition and uneven stirring at the bottom of the tank in traditional equipment, ensuring that the concentration of each batch of soda ash solution is uniform. At the same time, the intermittent rotation air supply can avoid excessive airflow turbulence that could cause solution splashing, thus improving operational safety. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0021] In a first aspect, the present invention provides a soda ash mixing hoist, such as Figure 1-6 As shown, the gantry crane includes a gantry frame 1, with a transverse preset track 2 and a longitudinal preset track 3 on the top of the gantry frame 1. A constant temperature chamber 4 is located below the gantry frame 1, and the lower end of the constant temperature chamber 4 has a hollow structure. The soda ash mixing gantry crane also includes: Several mixing barrels 5 are evenly distributed inside the constant temperature chamber 4, and the mixing barrels 5 are all placed in the working area below the gantry frame 1. A stirring rod 6 is installed at the top of the gantry frame 1; Several rotating air supply cylinders 7 are evenly distributed in the lower cavity of the constant temperature chamber 4, and the rotating air supply cylinders 7 correspond to the bottom of the mixing tank 5. The drive unit is used to drive the stirring rod 6 to move bidirectionally on the gantry frame 1. While the stirring rod 6 moves bidirectionally on the gantry frame 1, it drives the rotating air supply cylinder 7 to rotate intermittently via the transmission unit.

[0022] In this embodiment, during use, the gantry frame 1 serves as the overall load-bearing foundation, with a horizontal preset track 2 and a vertical preset track 3 laid on top to realize the two-dimensional bidirectional movement of the stirring rod 6; a constant temperature box 4 is fixedly installed below the gantry frame 1, and the lower end of the constant temperature box 4 is set as a cavity structure to provide installation and operation space for the rotary air supply cylinder 7; multiple sets of mixing barrels 5 are evenly distributed inside the constant temperature box 4, and all are placed in the standardized working area below the gantry frame 1 to ensure that the stirring rod 6 can be accurately aligned with each set of mixing barrels 5; the stirring rod 6 is installed on the top of the gantry frame 1 and can move freely along the track; the rotary air supply cylinder 7 is evenly distributed in the cavity at the lower end of the constant temperature box 4, and its position corresponds one-to-one with the bottom of the mixing barrel 5 to realize directional air supply disturbance at the bottom of the barrel; The driving unit drives the stirring rod 6 to slide horizontally and vertically in both directions. While the stirring rod 6 moves, the transmission unit simultaneously drives the rotating air supply cylinder 7 to rotate intermittently, realizing the coordinated linkage between the movement of the stirring rod 6 and the rotation of the rotating air supply cylinder 7. The rotating air supply cylinder 7 and the stirring rod 6 work together to form a dual mixing mode that combines mechanical stirring with bottom airflow disturbance.

[0023] In this embodiment, as Figure 1 , Figure 2 As shown, both the horizontal preset track 2 and the vertical preset track 3 are arranged in double rows. The horizontal preset track 2 slides on the vertical preset track 3. The vertical preset track 3 forms a frame-type load-bearing structure through the vertical end beam. The frame-type load-bearing structure further strengthens the overall rigidity and avoids problems such as track deformation and shaking after long-term use.

[0024] In this embodiment, as Figure 1 As shown, multiple mixing barrels 5 are arranged in a matrix and fixed below the gantry frame 1. Each mixing barrel 5 has an opening at the top to accommodate the insertion of the stirring rod 6. The size of the opening is compatible with the rod body and bottom blades of the stirring rod 6 to ensure that the stirring rod 6 can be smoothly inserted into the barrel for mixing without structural interference. The edges of the opening are rounded to prevent scratching and wear during the lifting and lowering of the stirring rod 6.

[0025] In this embodiment, as Figure 1 , Figure 6 As shown, the barrel is made of alkali-resistant and corrosion-resistant material. Equal gaps are reserved between adjacent mixing barrels 5 for heat dissipation and maintenance. The bottom of the barrel is sealed to the rotating gas supply cylinder 7 to prevent alkali solution from leaking into the cavity of the constant temperature box 4 and to ensure that the internal transmission components operate dry.

[0026] In this embodiment, as Figure 5 As shown, an axial airflow channel is opened inside the rotating air supply cylinder 7, and multiple sets of oblique jet nozzles 8 are evenly distributed on the outer side of the cylinder body. The jet direction of the jet nozzles 8 is set at an angle relative to the bottom inner wall of the mixing tank 5, which allows the airflow to be sprayed obliquely along the bottom inner wall of the mixing tank 5, forming a rotating airflow disturbance. Combined with the flow of the solution in the mixing tank 5, it disturbs the material deposited at the bottom of the tank in all directions, avoiding the formation of dead zones in the stirring. The multiple sets of jet nozzles 8 are evenly distributed to ensure that the airflow covers the entire bottom of the tank, without any local sedimentation blind spots.

[0027] In this embodiment, as Figure 3 , Figure 4 As shown, the drive unit includes: The system includes a bidirectional sliding motor 9, a transmission gear set 10, and a sliding block 11. The sliding block 11 is mounted on a horizontal preset track 2, and the top of the stirring rod 6 is fixedly installed at the bottom of the sliding block 11. The bidirectional sliding motor 9 drives the sliding block 11 to slide in a directional manner along the horizontal and vertical preset tracks 3 through the transmission gear set 10. The bidirectional sliding motor 9 serves as the core power source, transmitting power through the transmission gear set 10 to drive the sliding block 11 to slide in a directional and precise manner along the horizontal preset track 2 and the vertical preset track 3, thereby realizing the two-dimensional movement of the stirring rod 6. The system can freely switch between mixing tanks to complete the sequential mixing operation of multiple tanks.

[0028] In this embodiment, as Figure 5 As shown, the transmission unit includes: The connecting rod 12, the transmission rack 13, and the synchronous gear set 14 are all connected together. The connecting rod 12 is fixed to the lower end of the transmission gear set 10 near the longitudinal preset track 3. The transmission rack 13 is located at the end of the connecting rod 12. The synchronous gear set 14 is coaxially connected to the rotating air supply cylinder 7. The synchronous gear set 14 and the transmission rack 13 mesh. When the bidirectional sliding motor 9 drives the transmission gear set 10 to rotate and moves the stirring rod 6, the connecting rod 12 and the transmission rack 13 move synchronously. Through the meshing transmission of the gear and rack, the synchronous gear set 14 is driven to rotate, which in turn drives the rotating air supply cylinder 7 to rotate intermittently, so as to achieve targeted and precise synchronous stirring and air supply of alkaline solution in multiple barrels.

[0029] In this embodiment, as Figure 5 As shown, the axial air passage of the rotary air supply cylinder 7 is externally connected to an adjustable air source pressure regulating valve. The air source pressure regulating valve is fixed on the side wall of the gantry frame 1 and can freely control the air intake pressure and air flow. According to the different concentrations of soda ash and the amount of water, the corresponding air flow intensity is adapted to ensure sufficient disturbance effect while avoiding excessive air flow that could cause the solution to churn violently and overflow.

[0030] In this embodiment, as Figure 4 As shown, the stirring rod 6 is a vertically telescopic multi-segment rod structure. The stirring blades 15 can be detachably installed at the bottom of the stirring rod 6. The stirring blades 15 are arranged diagonally and staggeredly, and the length of the rod can be freely adjusted according to the depth of the mixing tank 5 to adapt to the operation requirements of different sizes of mixing tanks without the need to replace the stirring rod. The bottom of the stirring rod 6 adopts a detachable structure and is equipped with stirring blades 15. The stirring blades 15 are arranged diagonally and staggeredly to increase the stirring contact area and enhance the turbulence effect. The detachable design facilitates quick replacement after the blades wear, reducing operation and maintenance costs.

[0031] In this embodiment, as Figure 4As shown, a short turbulence rod 16 is provided between the multi-layered stirring blades 15 at the bottom of the stirring rod 6. The short turbulence rod 16 extends radially and rotates synchronously with the stirring rod. The short turbulence rod 16 can further break up the bubbles generated during the stirring process, and at the same time disturb the middle layer solution in the tank, make up for the blind spots in the stirring gap of the blades, and realize the all-round, dead-angle-free disturbance of the solution in the tank.
