Description

Technical Field

[0001] The invention relates to the technical field of shearing machines, in particular to a high-safety magnetic flocculation shearing machine that is easy to disassemble, assemble and repair. Background Art

[0002] Magnetic flocculation sedimentation technology is a commonly used technology for sewage treatment. It increases the specific gravity of floccules by adding magnetic powder in the flocculation stage, allowing the floccules to settle quickly. The magnetic powder can be recycled by the principle of magnetic attraction due to its magnetic characteristics. Before recycling the magnetic powder, the magnetic powder of the flocculation species must be separated from the colloid and then recycled by magnetic recovery equipment. At present, the equipment for separating magnetic powder mainly adopts shearing machine. For example, the authorization announcement number CN210994597U discloses a magnetic flocculation ceramic shearing machine, which includes a motor, a stirring bracket and a transmission shaft. The motor is installed above the stirring bracket, and the motor is connected to the transmission shaft through a coupling. The stirring bracket is installed together with the ceramic shearing cylinder below. A coupling is arranged inside the stirring bracket. The transmission shaft passes through a ceramic mechanical seal and enters the ceramic shearing cylinder. A magnetic mud outlet is welded on the upper left part of the ceramic shearing cylinder, and a magnetic mud inlet is welded on the lower right part of the ceramic shearing cylinder. The magnetic mud outlet, the ceramic shearing cylinder and the magnetic mud inlet together form a Z-type flow form. The ceramic shearing disk is provided with knife edges around it, and the outer surface of the ceramic shearing disk is a frosted surface. This patent uses a ceramic shearing disk to shear magnetic flocculation through high-speed rotation. The ceramic shearing disk is installed on a drive shaft, and the drive shaft is linked to the motor through a coupling. The structure is similar to that of the current shearing machine. There are some problems with using this type of shearing machine to shear magnetic flocculation. For example, the amount of colloid, magnetic powder and solid impurities in the magnetic flocculants after sewage treatment with different water qualities are different. If the magnetic flocculants are sheared with the same shearing force, the wear of the shearing disk will be accelerated and the life of the shearing disk will be reduced. The current shearing machine cannot adjust the shearing force in real time for different magnetic flocculants. Summary of the invention

[0019] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0020] Example 1

[0021] See also Figure 1 and Figure 2 As shown, a high-safety magnetic flocculation shearing machine which is easy to disassemble, assemble and overhaul comprises a main cylinder 1 and a shearing shaft 2, the outer surface of the shearing shaft 2 is evenly fixed with shearing knives 21, the shearing shaft 2 is rotatably connected to the main cylinder 1, the outer surface of the main cylinder 1 is fixed with a feed flange pipe 11 and a discharge flange pipe 12, the feed flange pipe 11 and the discharge flange pipe 12 are used for feeding and discharging respectively; illustratively, the magnetic flocculation enters through the feed flange pipe 11, and the shearing shaft 2 rotates at a high speed, driving the shearing knife 21 to shear the magnetic flocculation, and the sheared magnetic flocculation is discharged through the discharge flange pipe 12.

[0022] For further information, see Figure 2 and Figure 3 As shown, a fixed knife cylinder 3 is inserted and fixed inside the main cylinder body 1 and cooperates with the shear shaft 2 to shear the magnetic flocculation. The inner wall of the fixed knife cylinder 3 is staggered with fixed knives 31, and the shearing knives 21 and the fixed knives 31 are staggered in the upper and lower parts. The staggered shearing force is formed by the staggered shearing knives 21 and the fixed knives 31 to enhance the shearing effect on the magnetic flocculation. The shearing force can be controlled by controlling the distance between the shearing knife 21 and the fixed knife 31. For example, the smaller the distance between the shearing knife 21 and the fixed knife 31, the greater the extrusion force on the sheared object, that is, the greater the shearing force, and vice versa.

[0023] For details, see Figure 2 and Figure 3 As shown, the two ends of the main cylinder body 1 are respectively rotatably sealed and connected with a transmission seat 101 and a sleeve 102, and the two ends of the main cylinder body 1 are respectively fixed with a first end cover 13 and a second end cover 14, wherein the transmission seat 101 and the sleeve 102 are respectively rotatably sealed and connected with the first end cover 13 and the second end cover 14, and the two ends of the shear shaft 2 are respectively slidably connected with the transmission seat 101 and the sleeve 102, and the first end cover 13 is fixed with a driving motor 4, and the output end of the driving motor 4 is fixedly connected with the transmission seat 101, and the driving motor 4 is linked with the shear shaft 2 through the transmission seat 101; the purpose is that this transmission mode makes it easy to separate the shear shaft 2 from the transmission seat 101, thereby facilitating disassembly and maintenance; For more details, see Figure 4 , Figure 6 , Figure 7 and Fig.10 As shown, the inner wall of the transmission seat 101 is evenly fixed with a first convex tooth 1011, the outer surface of one end of the shear shaft 2 is evenly provided with a first tooth groove 22 that matches the first convex tooth 1011, the first convex tooth 1011 and the first tooth groove 22 are slidably connected, the outer surface of the other end of the shear shaft 2 is evenly provided with a second tooth groove 23, and the inner wall of the sleeve 102 is evenly fixed with a second convex tooth 1021 that matches the second tooth groove 23, the second tooth groove 23 and the second convex tooth 1021 are slidably connected, and both ends of the shear shaft 2 are sleeved with a spring 201, the spring 201 is used to provide elastic force for the shear shaft 2, specifically, the present embodiment is provided with two springs 201, respectively abutting against the transmission seat 101 and the sleeve 102; The purpose is that when the driving motor 4 drives the transmission seat 101 to rotate, the transmission seat 101 can drive the shear shaft 2 to rotate through the cooperation of the first convex tooth 1011 and the first tooth groove 22, and at the same time, it does not affect the shear shaft 2 sliding along the axis of the shear shaft 2 in the transmission seat 101, that is, sliding up and down, and controlling the position of the shear shaft 2 can change the distance between the shear knife 21 and the fixed knife 31, thereby changing the shearing force of the magnetic flocculation; for example, the smaller the distance between the shear knife 21 and the fixed knife 31, the greater the shearing pressure applied to the magnetic flocculation, and the greater the shearing force, and vice versa; and one end of the shear shaft 2 can be stably transmitted through the transmission seat 101, and the other end of the shear shaft 2 can be stably rotated through the sleeve 102 and the second end cover 14, and does not affect the axial movement of the shear shaft 2.

[0024] It is worth mentioning that see Figure 3 As shown, a positioning block 131 is fixed on the outer surface of the first end cover 13, and a positioning groove 32 is opened at the end of the fixed knife cylinder 3, and the positioning block 131 is engaged with the positioning groove 32, so as to limit the fixed knife cylinder 3; the purpose is to facilitate the fixing of the fixed knife cylinder 3 in the main cylinder body 1 and to facilitate the disassembly and maintenance of the fixed knife cylinder 3; it should be noted that the end of the fixed knife cylinder 3 away from the first end cover 13 can be quickly connected to the main cylinder body 1 through a fixing part such as a retaining spring or a buckle.

[0025] For details, see Figure 2 , Figure 3 and Figure 4 As shown, the second end cover 14 is equipped with an adjusting mechanism 5 for adjusting the distance between the shear shaft 2 and the fixed knife cylinder 3 to control the shear force of the shear magnetic flocculation. The adjusting mechanism 5 includes a second fixed seat 51, a pressure ring 52 and an adjusting ring 53. The second fixed seat 51 is fixed on the second end cover 14, the pressure ring 52 is slidably connected to the second fixed seat 51, and the pressure ring 52 is against the shear shaft 2 through a spring 201.

[0026] For more details, see Figure 5 , Figure 8 and Fig. 9 As shown, the adjusting ring 53 is rotatably connected with the second fixing seat 51, and the adjusting ring 53 is linked with the shear shaft 2 through the pressing ring 52. The adjusting ring 53 is used to rotate and control the height of the pressing ring 52. Specifically, the outer surface of the pressing ring 52 is evenly provided with wedge-shaped grooves 521, and the outer surface of the adjusting ring 53 is fixed with a pressing block 531 that abuts against the wedge-shaped groove 521, and the pressing block 531 is used to push the wedge-shaped groove 521; illustratively, by rotating the adjusting ring 53, the height of the adjusting ring 53 remains unchanged, which drives the pressing block 531 to push the wedge-shaped groove 521, and changes the height of the pressing ring 52. The pressing ring 52 can change the pressure applied to the spring 201, thereby pushing the shear shaft 2 and controlling the position of the shear shaft 2; Furthermore, in this embodiment, the two ends of the shear shaft 2 are connected to the transmission seat 101 and the pressure ring 52 respectively through springs 201, and the axial height of the shear shaft 2 is controlled by controlling the pressure applied to the shear shaft 2 by the spring 201, rather than directly controlling the axial height of the shear shaft 2 through the pressure ring 52; the purpose is to ensure the flexibility of the shear shaft 2 and increase the service life of the shear shaft 2; illustratively, when there are impurities with high hardness in the magnetic flocculant, such as metal particles, if the height of the shear shaft 2 is directly controlled by the pressure ring 52, it cannot passively slide axially. The shear shaft 2 needs to shear the metal particles with a fixed shear force, which increases the wear on the shear shaft 2. In this embodiment, the shear shaft 2 can passively slide axially. When the metal particles are sheared between the shear knife 21 and the fixed knife 31, if the shear force is greater than the elastic force of the spring 201, the shear shaft 2 can slide axially in the direction of the spring 201, avoiding the strong shearing of the metal particles and reducing the wear on the shear shaft 2.

[0027] For further information, see Figure 5 As shown, a pitch-adjusting motor 54 is fixed to the outer surface of the second fixed seat 51, a worm 541 is fixed to the output end of the pitch-adjusting motor 54, and the worm 541 is rotatably connected to the second fixed seat 51; a worm wheel 542 is meshed on the outer surface of the worm 541, and the worm wheel 542 is coaxially fixedly connected to the adjusting ring 53; illustratively, in this embodiment, the pitch-adjusting motor 54 can adopt a stepping motor or a servo motor, the pitch-adjusting motor 54 drives the worm 541 to rotate, the worm 541 can drive the worm wheel 542 to rotate, and the worm wheel 542 drives the adjusting ring 53 to rotate, so as to control the height of the pressing ring 52.

[0028] Example 2

[0029] See also Fig.11 As shown, based on the above embodiment, the improvement of this embodiment is that a controller is installed on the surface of the main cylinder 1, and the controller includes a data acquisition module, a shearing identification module and a control module, wherein each module and the pitch adjustment motor 54 are connected through a wired and / or wireless network; The data acquisition module is used to collect particle concentration. The data acquisition module of this embodiment adopts a fiber optic sensor and a spectrometer. The detection end of the fiber optic sensor is in the feed flange tube 11. The spectrometer can be configured in the control room according to actual conditions. The detection data of the fiber optic sensor is transmitted to the spectrometer for analysis through a wireless network to obtain the particle concentration. The spectrometer adopts a spectral analysis method, such as ultraviolet-visible light spectrum UV-Vis or infrared spectrum IR analysis. The specific analysis method is not specifically limited here. The shear recognition module inputs the particle concentration into the trained shear recognition model and outputs the shear force, which is used as the control parameter of the pitch-adjusting motor 54. The training method of the shear recognition model includes: Under the experimental environment, i groups of historical magnetic flocculation data and the shear force corresponding to the historical magnetic flocculation data are collected, where i is an integer greater than 1, and the historical magnetic flocculation data include particle concentration; Taking historical magnetic flocculation data and the shear force corresponding to the historical magnetic flocculation data as a sample set, dividing the sample set into a training set and a test set, taking the historical magnetic flocculation data in the training set as the input of a shear recognition model, taking the shear force in the training set as the output of the shear recognition model, training the shear recognition model, and outputting a shear recognition model that meets a preset accuracy, wherein the shear recognition model is a naive Bayes model or a support vector machine model; Historical magnetic flocculation data are collected in an experimental environment or historical sewage treatment records. Multiple groups of magnetic flocculation data are sheared in turn using different shearing forces. Technical personnel in the field analyze the sheared samples and select the shearing force corresponding to the optimal sample to correspond to the magnetic flocculation data. The optimal shearing force corresponds to the best shearing effect. The magnetic flocculation data in multiple groups are constantly changing, so that the shearing force corresponding to i groups of historical magnetic flocculation data can be obtained.

[0030] The control module controls the pitch-adjusting motor 54 to drive the worm 541 to rotate based on the shear force, and specifically controls the rotation angle of the pitch-adjusting motor 54. A technician in this field calculates the corresponding relationship between the rotation angle value of the pitch-adjusting motor 54 and the corresponding shear force under an experimental environment, and based on this relationship, converts the shear force into a control signal corresponding to the rotation angle of the pitch-adjusting motor 54. The control module can control the rotation of the pitch-adjusting motor 54 based on this control signal.

However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
