Description

Technical Field

[0001] This utility model belongs to the field of screening equipment technology, specifically relating to a ceramic slurry screening machine with an automatic iron removal and diversion device. Background Technology

[0002] In the traditional ceramic raw material crushing, grinding, and conveying processes, incompletely crushed coarse particles in the raw materials can lead to uneven surfaces on the formed ceramic blanks, making them prone to cracking during firing. Furthermore, iron filings from equipment wear and iron-containing minerals embedded in the raw materials can undergo oxidation during high-temperature firing, forming noticeable discoloration that not only damages the visual appeal of the ceramic product but also renders it unusable. Therefore, coarse impurities and iron foreign objects in ceramic slurry directly affect the performance and appearance of finished ceramic products, making reliable ceramic slurry impurity and iron removal equipment crucial for the development of the ceramic industry.

[0003] Currently, existing equipment for removing impurities and iron from slurry still has many problems in practical applications. For example, patent application number ZL202221871521.0 discloses a vibrating screen for continuous iron removal from ceramic slurry. It uses a crushing cylinder to perform secondary crushing of the slurry, and combines the counter-rotation of the stirring frame and the stirring shaft with the vibration of the screen plate to achieve multi-stage iron removal. Although it can achieve continuous processing, the overall structure is complex and requires three sets of power devices: a crushing motor, a stirring motor, and a vibrating motor. This not only increases the manufacturing cost of the equipment but also increases the difficulty of later maintenance. In addition, the slurry needs to pass through the crushing cylinder and the conveying pipe before entering the screen box. The conveying path is long, which can easily cause residue at the pipe connection and blockage, affecting the continuity of production.

[0004] Therefore, how to design a ceramic slurry screening machine that integrates efficient screening, precise iron removal and convenient maintenance functions, and has a relatively simple structure, has become an urgent problem to be solved. This is also a technical challenge in improving the level of ceramic slurry treatment technology. Utility Model Content

[0005] In view of the problems of complex structure, difficult maintenance and long conveying path leading to blockage in existing mud impurity and iron removal equipment in the background technology, this utility model provides a ceramic mud slurry screening machine with an automatic iron removal and diversion device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a ceramic slurry screening machine with an automatic iron removal and diversion device, comprising a frame and a support fixed thereon, a housing mounted on the frame, a spiral blade mounted on the housing via a bearing seat, the rotating shaft of the spiral blade being connected to the output shaft of a motor via a pulley mechanism, the motor being mounted on the support, an inlet and an outlet provided at both ends of the housing, a receiving box fixed at the bottom of the housing, an arc-shaped screen at the bottom of the housing located inside the receiving box, a discharge port provided at the bottom of the receiving box, an iron removal port provided on the end face of the housing located on the side of the discharge port, a flip-top plate provided on the iron removal port, a magnet block vertically arranged on the flip-top plate, the magnet block being located directly above the discharge port.

[0007] As a further supplement to the above technical solution, the bottom surface of the receiving box is arranged at an inclination, and the discharge port is located on its lowest side.

[0008] As a further supplement to the above technical solution, an inspection port is provided on the top of the chassis, and a sealing cover is bolted to it.

[0009] As a further supplement to the above technical solution, a protective cover is bolted between the frame and the support, and the protective cover covers the pulley mechanism.

[0010] As a further supplement to the above technical solution, a rotating frame is provided on the inner side of the flip cover, and an insert box and a limiting block are fixed on the rotating frame. The magnet block is set inside the insert box, and the limiting block is used to limit the rotation angle of the rotating frame.

[0011] As a further supplement to the above technical solution, the magnet is embedded in the insert block, and the insert block fixes the magnet on the rotating frame by being inserted into the insert box.

[0012] As a further supplement to the above technical solution, a retaining strip is fixed at the insertion port of the insertion box. The retaining strip has an arc surface on the outward side, which facilitates the insertion block to slide into the insertion box to form a snap-fit ​​engagement.

[0013] As a further supplement to the above technical solution, a pin is provided on the flip cover plate through a sleeve, and a positioning hole is provided on the iron removal port. After the pin passes through the sleeve, it is inserted into the positioning hole to lock and fix the flip cover plate on the iron removal port.

[0014] As a further supplement to the above technical solution, a handle groove is provided on the plug, which is used by the operator to hold and remove or insert the plug from the plug box.

[0015] As a further supplement to the above technical solution, a handle is fixed on the outside of the flip cover, and the handle is used by the operator to open or close the flip cover.

[0016] Compared with the prior art, the present invention has the following advantages: 1. This utility model adopts a screw conveyor design, which uses a motor and pulley to drive the screw blades, simultaneously realizing the functions of slurry conveying, screening, and iron removal. It eliminates the need for additional power units such as crushing motors and mixing motors, significantly simplifying the overall equipment structure. Furthermore, the slurry is directly conveyed and impurities are treated inside the machine housing, eliminating the need for additional conveying paths. After impurity removal, the slurry can effectively avoid blockages during conveying, further ensuring the continuity of subsequent production.

[0017] 2. The bottom of the casing of this utility model adopts an arc-shaped screen design. By utilizing the axial thrust of the spiral blades, the mud can fully contact the arc-shaped screen during the movement, further improving the mud removal efficiency. The inclined design of the bottom surface of the receiving box is conducive to guiding the screened mud to flow quickly to the discharge port and avoid the mud from accumulating in the receiving box.

[0018] 3. In terms of iron removal, this utility model uses a flip-top process to align the magnetic block directly above the discharge port, completely covering it. When iron-containing foreign objects carried by the screened impurities move towards the discharge port, they are firmly attracted by the magnetic block, achieving efficient separation of the slurry and iron impurities. Furthermore, the limiting block design ensures that the magnetic block remains in an effective adsorption position, further guaranteeing the iron removal effect.

[0019] 4. This utility model features an inspection port with a sealing cover on the top of the casing. Operators can easily inspect and maintain components such as the spiral blades and arc-shaped screen inside the casing by opening the sealing cover. Simultaneously, the flip-top is fixed to the iron removal port by a pin; operators can simply pull out the pin to open the flip-top and directly clean the iron impurities adsorbed on the surface of the magnet. The magnet is fixed to the rotating frame by a locking block, allowing for quick replacement of the magnet after demagnetization. The entire maintenance process is simple, requires no complex tools, and saves maintenance time and labor costs.

[0020] 5. This utility model also adds a protective cover, which can prevent operators from accidentally coming into contact with the running pulleys and belts, thus improving the safety of the equipment during operation. Attached Figure Description

[0023] To further illustrate the technical solution of this utility model, the following description is in conjunction with the appendix. Figures 1 to 4 Based on the specific implementation process, we will further illustrate this utility model through the optimal embodiment. In the actual implementation process, the relevant purchased motor equipment and key design points are as follows: the motor selected is a YE2 series three-phase asynchronous motor, and the magnet block is a neodymium iron boron strong magnet. The insert block uses ABS engineering plastic injection molding, which has good wear resistance while ensuring that the magnet block is not difficult to disassemble due to magnetic attraction during removal. Therefore, this embodiment only illustrates the technical solution of this utility model and is not a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model. For example, the motor model or the installation method of the magnet block can be adjusted according to actual needs, and the material of the insert block can also be replaced, such as using polycarbonate material, without affecting the technical effect of this utility model.

[0024] As attached Figures 1 to 3As shown, a ceramic slurry screening machine with an automatic iron removal and diversion device is implemented as follows: The frame 1 is made of rectangular steel pipe welded together, and the housing 3 is made of stainless steel plate bent and welded together, and fixed to the frame 1 by bolt connection. An inlet 6 and an outlet 7 are welded onto the housing 3, with the inlet 6 located on the upper side near the motor 4, and the outlet 7 located on the lower side, forming a smooth flow path for the slurry from inlet to outlet. The two ends of the rotating shaft of the spiral blade 5 are installed at the corresponding shaft holes on both sides of the housing 3 through deep groove ball bearing seats, and the bearing seats are fastened to the housing 3 with bolts. A support 2 is welded to one side of the frame 1 via a hanger rod to install the motor 4; the motor 4 is a YE2 series three-phase asynchronous motor, fixed to the support 2 with four sets of bolts. The output shaft of the motor 4 is equipped with the driving pulley of the pulley mechanism 13, and the end of the rotating shaft of the spiral blade 5 is equipped with the driven pulley of the pulley mechanism 13. A V-belt is fitted between the driving pulley and the driven pulley. A protective cover 14 is bolted between the frame 1 and the support 2, completely covering the pulley mechanism 13 to prevent safety hazards to operators during operation. A receiving box 9 is welded to the bottom of the housing 3. An arc-shaped screen 15, 80-120 mesh, is installed on the bottom arc section of the housing 3 inside the receiving box 9 and is fixed to the bottom arc section of the housing 3 by peripheral welding. The bottom surface of the receiving box 9 is inclined at a 5-10° angle, and the discharge port 10 is welded to the lowest side of the bottom surface of the receiving box 9. An iron removal port 11 is opened on the end face of the housing 3 on one side of the discharge port 7. The edge of the iron removal port 11 is connected to the flip-top plate 12 by a hinged connector. A magnet 19 is vertically installed on the flip-top plate 12, and the magnet 19 must be precisely aligned above the discharge port 7 to ensure coverage of the entire cross-sectional area of ​​the discharge port 7.

[0025] In this embodiment, as shown in the appendix Figure 4 As shown, the specific connection method of the magnet block is as follows: A fixed insertion box 17 is welded onto the rotating frame 16. The insertion box 17 is a rectangular slot-shaped structure with an open top. The magnet block 19 is embedded in the pre-set groove of the insertion block 18. Through insertion and fitting, the insertion block 18 is fully embedded into the insertion box 17, thereby indirectly fixing the magnet block 19 to the rotating frame 16. A retaining strip 20 is fixed to the inner side of the opening edge of the insertion box 17. When the insertion block 18 is fully inserted into the insertion box 17, the retaining strip 20 and the top edge of the insertion block 18 form a retaining connection, preventing the insertion block 18 from coming out of the insertion box 17. A pin 22 is set on the flip cover 12 through a sleeve. A corresponding positioning hole 23 is set on the iron removal port 11. The pin 22 passes through the sleeve and is inserted into the positioning hole 23, which can lock the flip cover 12 onto the iron removal port 11, preventing the flip cover 12 from loosening during equipment operation. Meanwhile, a handle 24 is fixed on the outside of the flip cover 12 to facilitate the operator to open or close the flip cover 12; a handle groove 25 is provided on the insert block 18, and the operator can take the insert block 18 out of the insert box 17 or insert it by holding the handle groove 25, which facilitates the replacement and maintenance of the magnet block 19.

[0026] Furthermore, an inspection port 8 is provided on the top of the chassis 3, and a sealing cover is connected to the inspection port 8 by bolts. The internal components of the chassis 3 can be inspected and maintained by opening the sealing cover.

[0027] Its working principle and specific working method are as follows: Before starting the equipment, the operator confirms that the pin 22 has been inserted into the positioning hole 23 to ensure that the flip cover 12 is tightly closed. Then, the three-phase power supply of the motor 4 is turned on. After the motor 4 is powered on, it drives the spiral blade 5 to rotate through the pulley mechanism 13. The operator feeds the ceramic slurry to be screened into the machine box 3 at a uniform speed through the feed port 6. After the slurry enters the machine box 3, it moves along the inner wall of the machine box 3 towards the discharge port 7 under the axial thrust of the spiral blade 5. During the movement, the slurry with a particle size smaller than the aperture of the arc screen 15 passes through the arc screen 15 and falls into the receiving box 9 below. With the guidance of the inclined bottom surface of the receiving box 9, it flows towards the discharge port 10 and is finally discharged, completing the slurry screening process. Iron impurities mixed in the slurry cannot pass through the screen because their particle size is larger than the aperture of the arc screen 15 and are carried away with the slurry. Moving towards the discharge port 7, when iron impurities reach the vicinity of the discharge port 7, they are attracted by the magnetic force of the neodymium iron boron strong magnet 19 on the flip cover plate 12 and firmly adsorbed onto the surface of the magnet 19, thus achieving the separation of mud and iron impurities. After the equipment has been running for a certain period of time, it is necessary to clean the iron impurities adsorbed on the surface of the magnet 19. At this time, the operator only needs to pull out the pin 22, hold the handle 24 and flip the flip cover plate 12 outward to directly clean the impurities. If it is necessary to replace the magnet 19, the operator can insert his / her fingers into the handle groove 25, pull the insert 18 outward, pull it out of the insert box 17, replace it with a new insert 18 embedded with the magnet 19, and insert it along the insertion opening of the insert box 17 until it is locked and limited by the locking strip 20. The design of the limiting block 21 can ensure that the magnet 19 is always in an effective adsorption position directly above the discharge port 7.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
