Abstract
Description
Technical Field
[0001] This utility model relates to the field of surface treatment agent production technology, and in particular to a slurry mixing device for leather production. Background Technology
[0002] In the leather production and processing industry, the uniform mixing of slurry is a key process to ensure the quality and surface consistency of leather finishing. In existing technologies, commonly used slurry mixing devices mostly adopt a fixed mixing structure, that is, the mixing shaft and mixing paddle are fixedly installed above or inside the mixing drum by bearings or brackets, and the mixing paddle is always located inside the drum and cannot be moved out of the mixing area after mixing is completed.
[0003] While this fixed structure can meet basic mixing requirements, in actual use, because the agitator is immersed in the slurry for a long time, a large amount of sticky slurry will remain on the surface of the blades and the agitator shaft after the mixing operation is completed. Since the agitator cannot be lifted out of the cylinder, the operator can only clean it in the narrow opening or inside the cylinder. This is not only inconvenient to operate and incomplete to clean, but also makes it easy for the slurry to dry and become difficult to remove, which in turn affects the purity of subsequent batches of slurry and may even lead to cross-contamination. Utility Model Content
[0004] The purpose of this invention is to provide a slurry mixing device for leather production, which can conveniently lift the mixing paddle from the device after the slurry mixing operation is completed, so as to facilitate the cleaning of the mixing paddle.
[0005] To achieve the above objectives, a slurry mixing device for leather production is provided, comprising a hollow housing with a mixing cylinder fixedly installed inside. The mixing cylinder extends upward through the housing and has a discharge port extending downward through the housing at its bottom. A mixing mechanism includes a mounting plate, a mixing shaft, a first mixing paddle, a second mixing paddle, a support rod, a nut, a lifting screw, a bracket, a reduction motor, and a stepper motor. The mounting plate is positioned above the mixing cylinder. The mixing shaft is rotatably mounted on the lower end of the mounting plate via bearings and is located in the middle of the mixing cylinder. The first mixing paddle is fixedly mounted on the lower end of the mixing shaft. Multiple second mixing paddles are equidistantly fitted onto the surface of the mixing shaft. The support rod is located on one side of the mixing cylinder, and its top end is fixedly connected to the mounting plate. The nut is fixedly mounted on the bottom end of the support rod away from the mounting plate. The lifting screw is rotatably mounted on the bottom of the mounting plate via bearings. The mixing mechanism is vertically mounted, with a lifting screw passing through the middle of the nut and threadedly engaged with it. A bracket is fixedly installed on the upper part of the equipment housing. The upper end of the lifting screw passes through the bracket and is rotatably connected to it via a bearing. A reduction motor is fixedly installed on the upper part of the mounting plate, and its output shaft is fixedly connected to the upper end of the mixing shaft via a coupling. A stepper motor is fixedly installed on the upper part of the bracket, and its output shaft is fixedly connected to the upper end of the lifting screw via a coupling. Guide rails are located on both sides of the mixing mechanism and slide within it. These guide rails are fixedly installed inside the equipment housing and extend upwards to the outside of the housing. An operation panel is fixedly installed on the outside of the equipment housing. A filtration mechanism is fixedly installed at the discharge port at the lower end of the mixing drum, with its end away from the mixing drum extending upwards into the equipment housing and fixedly connected thereto. A storage mechanism is located below the equipment housing, with its input end connected to the filtration mechanism. This design allows for convenient lifting of the mixing paddle from the device after the slurry mixing operation is completed, facilitating cleaning of the paddle.
[0006] Preferably, support legs are fixedly connected to the four lower corners of the device housing to support the device.
[0007] Preferably, the stirring mechanism further includes sliding columns, which are fixedly installed on both sides of the support rod. The sliding columns are disposed in the guide rail and slide along the inner wall of the guide rail. The cooperation between the sliding columns and the guide rail ensures the straightness and stability of the mounting plate during lifting and lowering, prevents deflection, and improves the smoothness of the stirring mechanism's operation.
[0008] Preferably, the filtration mechanism includes a discharge pipe, a conveying pipe, a filtrate discharge pipe, a slag discharge pipe, a first filter screen, spiral blades, and a conveying motor. The upper end of the discharge pipe is connected to the discharge port of the equipment housing. The conveying pipe is fixedly installed at the end of the discharge pipe away from the equipment housing and is connected to the discharge pipe. The end of the conveying pipe away from the discharge pipe is inclined upward and extends into the equipment housing. The filtrate discharge pipe and the slag discharge pipe are respectively located at the bottom ends of the conveying pipe, and the filtrate discharge pipe is located at the connection between the discharge pipe and the conveying pipe. The first filter screen is located at the connection between the conveying pipe and the filtrate discharge pipe and is in contact with the inner wall of the conveying pipe. The spiral blades are located in the conveying pipe, and the outer side of the spiral blades contacts the inner wall of the conveying pipe. The conveying motor is fixedly installed at the end of the conveying pipe away from the discharge pipe, and the output shaft of the conveying motor passes through the conveying pipe and is rotatably connected to the conveying pipe through a bearing. The output shaft of the conveying motor is fixedly connected to the shaft of the spiral blades through a coupling. After the slurry enters the conveying pipe through the discharge pipe, it is conveyed upward by the spiral blades. The liquid passes through the first filter screen and is discharged from the filtrate discharge pipe, while the solid residue is pushed to the slag discharge pipe for discharge. This achieves efficient solid-liquid separation and automatic slag discharge, avoids filter screen clogging, and reduces the frequency of manual cleaning.
[0009] Preferably, the storage mechanism includes a storage tank, a second filter screen, and a door. The top of the storage tank is fixedly connected to the lower end of the slag discharge pipe, and the storage tank is connected to the conveying pipe through the slag discharge pipe. A drain outlet is provided at the bottom of the storage tank. The second filter screen is fixedly installed inside the storage tank, and the door is closable and installed on one side of the storage tank. After the residue discharged from the slag discharge pipe enters the storage tank, it is filtered again by the second filter screen. The residual liquid is discharged from the bottom drain outlet, and the solid residue can be cleaned by periodically opening the door, further improving the solid-liquid separation effect and the convenience of material recovery.
[0010] Preferably, the inclination angle of the conveying pipe is 15° to 45°. This ensures that the spiral blades effectively transport solid residue upwards for discharge, while also allowing the filtrate to flow smoothly to the filtrate discharge pipe under gravity.
[0011] Preferably, the control panel is electrically connected to the stirring mechanism and the filtering mechanism. The control panel allows for centralized control of stirring height, stirring speed, and filtering start / stop.
[0012] Preferably, the bottom of the support leg is provided with a shock-absorbing pad to reduce vibration and noise during device operation.
[0013] Preferably, the first agitator is an anchor-type agitator, and the second agitator is a paddle-type agitator. The anchor-type agitator can effectively scrape up the deposited slurry at the bottom of the mixing drum, while the paddle-type agitator shears and mixes the upper layer of slurry. The combination of the two can achieve all-round, multi-level uniform mixing of the slurry.
[0014] The above-mentioned solution has the following beneficial effects:
[0015] 1. By setting guide rails and a lifting structure that slides with the mixing mechanism, the mixing shaft, the first mixing blade and the second mixing blade can be lifted out of the mixing drum as a whole after mixing is completed. This allows the mixing blades to be completely removed from the slurry surface or even moved out of the drum, making it convenient for operators to thoroughly clean the blades and mixing shaft, avoiding slurry residue from drying, effectively preventing cross-contamination, and reducing equipment maintenance difficulty and downtime.
[0016] 2. The filtration mechanism adopts an inclined conveying pipe in conjunction with spiral blades and a first filter screen. The slurry is conveyed upward under the push of the spiral blades, the filtrate flows out from the filtrate discharge pipe, and the solid residue is pushed to the slag discharge pipe for discharge. This realizes continuous and automatic solid-liquid separation, avoiding the drawbacks of traditional filter screens that are easy to clog and require frequent shutdowns for cleaning.

The output shaft is fixedly connected to the upper end of the lifting screw 307 via a coupling; the guide rails 4 are located on both sides of the stirring mechanism 3 and slide in cooperation with the stirring mechanism 3. The guide rails 4 are fixedly installed in the equipment housing 1 and extend upward to the outside of the equipment housing 1; the operation panel 5 is fixedly installed on the outside of the equipment housing 1; the filter mechanism 6 is fixedly installed at the discharge port at the lower end of the stirring drum 2, and its end away from the stirring drum 2 extends upward into the equipment housing 1 and is fixedly connected to the equipment housing 1; the storage mechanism 7 is located below the equipment housing 1, and its input end is connected to the filter mechanism 6.

The sliding columns cooperate with the guide rail to ensure the straightness and stability of the mounting plate 301 when it is raised and lowered, prevent deflection, and improve the smoothness of the stirring mechanism 3.
[0033] like Figure 4 As shown, the filtration mechanism 6 includes a discharge pipe 601, a conveying pipe 602, a filtrate discharge pipe 603, a slag discharge pipe 604, a first filter screen 605, a spiral blade 606, and a conveying motor 607. The upper end of the discharge pipe 601 is connected to the discharge port of the equipment housing 1. The conveying pipe 602 is fixedly installed at the end of the discharge pipe 601 away from the equipment housing 1, and the conveying pipe 602 is connected to the discharge pipe 601.

At the connection between the feed pipe 601 and the conveying pipe 602, a first filter screen 605 is disposed at the connection between the conveying pipe 602 and the filtrate discharge pipe 603, and the first filter screen 605 is attached to the inner wall of the conveying pipe 602. A spiral blade 606 is disposed in the conveying pipe 602, and the outer side of the spiral blade 606 contacts the inner wall of the conveying pipe 602.

[0034] like Figure 5 As shown, the storage mechanism 7 includes a storage tank 701, a second filter screen 702, and a door 703. The top of the storage tank 701 is fixedly connected to the lower end of the slag discharge pipe 604, and the storage tank 701 is connected to the conveying pipe 602 through the slag discharge pipe 604. A drain outlet is provided at the bottom of the storage tank 701.

[0035] like Figure 4 As shown, the inclination angle of the conveying pipe 602 is 15° to 45°, with 20° being the preferred inclination angle.

[0038] like Figure 3 As shown, the first agitator 303 is an anchor-type agitator, and the second agitator 304 is a paddle-type agitator. The anchor-type agitator can effectively scrape up the deposited slurry at the bottom of the mixing drum, while the paddle-type agitator shears and mixes the upper layer of slurry. The combination of the two can achieve all-round, multi-level uniform mixing of the slurry.
[0039] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.
[0040] Working principle: Before starting, the stirring parameters are set via the operation panel 5; during stirring, the stepper motor 310 drives the lifting screw 307 to rotate, which in turn drives the support rod 305 and the mounting plate 301 to descend along the guide rail 4 via the nut 306, so that the first stirring paddle 303 and the second stirring paddle 304 extend into the slurry in the stirring drum 2. The reduction motor 309 drives the stirring shaft 302 to rotate, which drives the anchor-type stirring paddle and the paddle-type stirring paddle to mix the slurry in multiple layers and in all directions; during the stirring process, the stepper motor 310 can rotate in both directions, so that the stirring paddle moves up and down in the drum, thereby fully stirring the slurry at different depths;
[0041] After mixing is completed, the stepper motor 310 rotates in the opposite direction, and the lifting screw 307 drives the mounting plate 301 and the stirring shaft 302 to rise, lifting the first stirring paddle 303 and the second stirring paddle 304 out of the mixing drum 2 and above the slurry surface, so that the operator can clean them directly.
[0042] The mixed slurry enters the conveying pipe 602 from the discharge port at the bottom of the mixing drum 2 through the discharge pipe 601. The conveying motor 607 drives the spiral blades 606 to rotate, pushing the slurry upward along the inclined conveying pipe 602. During the pushing process, the liquid in the slurry is filtered by the first filter screen 605 under the action of gravity and pressure and discharged from the filtrate discharge pipe 603. The solid residue is pushed to the high end of the conveying pipe 602 by the spiral blades 606 and falls into the storage tank 701 through the slag discharge pipe 604. The residue falling into the storage tank 701 is further filtered by the second filter screen 702. The residual liquid is discharged from the drain port at the bottom of the storage tank 701, and the solid waste accumulates on the second filter screen 702. When the waste accumulates to a certain amount, the tank door 703 is opened for cleaning.
