Description

Technical Field

[0001] This utility model relates to the field of investment casting technology, and in particular to a slurry preparation device for preventing sedimentation of slurry. Background Technology

[0002] Investment casting involves coating a wax model with several layers of liquid refractory slurry and solid refractory sand, drying and dewaxing to create a hard shell, then firing it at high temperature, pouring in molten metal, and finally removing the shell to obtain the cast product. In the automated production process of the shell, a robot typically picks up the wax model and places it into a slurry tank for coating with refractory slurry. However, the refractory slurry in the tank is a liquid mixture that settles very easily and requires continuous and rapid stirring using specialized equipment to prepare it.

[0003] Current slurry preparation methods have the following shortcomings:

[0004] 1) The pulping equipment is fixed and cannot be moved. Due to the limited space in the production site, the pulping equipment can only be installed against the wall or in a corner that does not affect production operations. It is far away from the dip-coating tank. The pulp produced cannot be transported to the dip-coating tank for stirring in time. Over time, there is a risk of the pulp settling. Once the pulp sets, its quality and performance will change, which will affect the wax model coating and, in severe cases, the quality of the mold shell.

[0005] 2) During the slurry preparation process, only one vertically lifting stirring paddle stirs the slurry. The stirring position is in the middle, which cannot fully stir the slurry on the sides and bottom of the mixing tank. Moreover, the slurry preparation efficiency is low and it takes a long time.

[0006] 3) During the slurry preparation process, there is no cooling system to remove the heat generated during the mixing process, so the temperature of the slurry cannot be controlled.

[0007] For the reasons mentioned above, there is a need to provide a pulping equipment that prevents pulp sedimentation in order to avoid pulp sedimentation. Utility Model Content

Further, the upper reinforcing ring 44 is also provided with a cooling system mounting base 41 and a high-speed agitator inclined support 43; there are two high-speed agitator inclined supports 43, welded to the upper reinforcing ring 44; the high-speed agitator inclined supports 43 are designed with an inclined surface to support and fix the motor base 76 of the high-speed agitator 7, allowing the high-speed agitator 7 to extend obliquely downwards into the inner barrel 5, as shown. Figure 1 As shown.

[0053] In one specific embodiment of this utility model, such as Figure 5 As shown, the inner tub 5 includes: a lower reinforcing ring 51, a second cylindrical wall 52, an upper reinforcing ring 53, and a bottom 54. The bottom 54 is welded to the bottom of the second cylindrical wall 52, and the lower reinforcing ring 51 and the upper reinforcing ring 53 are welded to the outside of the second cylindrical wall 52.

The lower end of the transmission shaft 23 is driven to rotate by the geared motor 21, thereby driving the connecting plate 24 to rotate. The connecting plate 24 is designed with mounting holes and is connected to the bottom 54 of the inner barrel 5 by fastening screws, so that the inner barrel 5 can rotate with the transmission shaft 23.

[0056] In one specific embodiment of this utility model, the high-speed stirring paddle 7 includes: an impeller 701, an impeller shaft 702, and a motor 705; the motor 705 is connected to the impeller shaft 702; the impeller 701 is installed at the end of the impeller shaft 702 and can rotate under the drive of the motor 705.

[0057] like Figure 7 , Figure 8 As shown, the high-speed mixing paddle 7 also includes: a coupling 703, a second handle 704, a motor base 706, a rotating support 707, a pin 708, a limiting block 709, a rotating shaft 710, and an anti-loosening nut 711. Specifically, the impeller 701 is fixedly mounted to the end of the impeller shaft 702 by welding or bolting, and can rotate with the impeller shaft 702 to mix the slurry at high speed. The impeller shaft 702 is fixedly connected to the motor 705 through the coupling 703, and is driven to rotate by the motor 705. The second handle 704 and the motor 705 are both mounted on the motor base 706. Two rotating supports 707 are welded to the motor base 706. One end of the rotating shaft 710 is designed as a flat plate, which is sandwiched between the two rotating supports 707 and connected to the rotating supports 707 via a pin 708. The other end of the rotating shaft 710 is designed as a round shaft with a threaded section at the end. An anti-loosening nut 711 is installed on the threaded section and is clamped and fixed to the high-speed stirring paddle mounting base 17 of the movable impeller base 1. Two limiting blocks 709 are welded to the motor base 706 and are used to limit the installation position of the motor 705.

[0058] like Figure 1 , Figure 7 , Figure 8As shown, the high-speed agitator 7 extends obliquely downwards into the inner barrel 5 via the high-speed agitator inclined support 43 of the outer barrel 4 and the high-speed agitator mounting base 17 of the movable impeller base 1. During installation of the high-speed agitator 7: First, the upper flat portion of the rotating shaft 710 is hinged to the rotating support 707 via a pin 708. The lower cylindrical portion of the rotating shaft 710 is inserted into the round hole of the high-speed agitator mounting base 17 of the movable impeller base 1. Then, the lower end of the rotating shaft 710 is tightened with an anti-loosening nut 711, ensuring that the rotating shaft 710 can only rotate within the round hole of the high-speed agitator mounting base 17 and cannot be pulled upwards. Next, the motor base 706 is placed against the inclined surface of the high-speed agitator inclined support 43 of the outer barrel 4, and two limiting blocks 709 are secured to the outside of the two high-speed agitator inclined supports 43, completing the installation and limiting of the motor 705. After installation, the rotating support 707 is hinged to the rotating shaft 710 via the pin 708. By pushing the second handle 704 downward, the motor base 706 can rotate around the pin 708 with the motor 705, thereby allowing the high-speed stirring paddle 7 to be lifted vertically out of the inner barrel 5. At the same time, the two limiting blocks 709 are released from the obstruction of the two high-speed stirring paddle inclined supports 43, allowing the motor base 706 to rotate with the motor 705 through the rotating shaft 710 in the round hole of the high-speed stirring paddle mounting base 17, thereby allowing the high-speed stirring paddle 7 to be lifted horizontally out of the inner barrel 5.

[0059] In one specific embodiment of this utility model, the slow-speed stirring paddle 9 further includes: a stirring rod 92 and a bracket 99; the stirring rod 92 is installed on the outer barrel 4 or the movable slurry tank seat 1 via the bracket 99, and the stirring rod 92 is vertically arranged in the inner barrel 5; the bottom paddle 91 is fixedly installed at the bottom of the stirring rod 92 and is arranged perpendicular to the stirring rod 92; the bottom paddle 91 is inclined relative to the bottom 54 of the inner barrel 5 and is used to disturb the slurry at the bottom of the inner barrel 5; the side paddle 93 is fixedly installed on the side of the stirring rod 92 and is used to disturb the slurry at the barrel wall 52 of the inner barrel 5.

[0060] In this embodiment, the slow-speed stirring paddle 9 is installed on the outer barrel 4 or the support frame 12. When the reduction motor 21 drives the inner barrel 5 to rotate, the slow-speed stirring paddle 9 remains stationary. The inclined bottom paddle 91 of the slow-speed stirring paddle 9 can push the slurry at the bottom of the inner barrel 5 upward, so that it enters the stirring range of the high-speed stirring paddle 7 for stirring. The side paddle 93 of the slow-speed stirring paddle 9 can push the slurry close to the inner wall of the inner barrel 5 to the central axis position of the inner barrel 5, and then perform high-speed stirring through the impeller 701 of the high-speed stirring paddle 7. Finally, the slurry inside the inner barrel 5 is circulated and stirred, which improves the stirring efficiency and can prevent the slurry at the bottom or edge of the barrel from settling or solidifying.

[0061] Furthermore, the stirring rod 92 is clamped and fixed by the clamp 94, and the clamp 94 is horizontally slidably mounted on the bracket 99. By adjusting the relative position of the clamp 94 and the bracket 99, the distance between the stirring rod 92 and the side paddle 93 and the barrel wall 52 of the inner barrel 5 can be adjusted.

[0062] Furthermore, the stirring rod 92 is disposed in the circular hole of the clamp 94 and fastened by the fastening bolt 95; by adjusting the circumferential installation angle of the stirring rod 92 in the clamp 94, the deflection angle of the bottom paddle 91 in the inner barrel 5 can be adjusted; by adjusting the axial installation position of the stirring rod 92 in the clamp 94, the distance between the bottom paddle 91 and the bottom 54 of the inner barrel 5 can be adjusted.

[0063] like Figure 9 As shown, the slow-speed mixing paddle 9 also includes: fastening bolts 95 and quick-connect elbows 98.

[0064] Specifically, the bottom impeller 91 is welded to the bottom of the stirring rod 92 at a certain angle to the horizontal direction. The side impeller 93 is welded to the side of the stirring rod 92 perpendicular to the horizontal direction. The clamp 94 is made of a rectangular steel piece with a circular through hole at one end and an opening slot on one side of the circular through hole. A fastening bolt 95 is installed on the side of the opening slot. When the stirring rod 92 passes through the circular through hole, the gap between the opening slots is reduced by tightening the fastening bolt 95, thereby clamping the stirring rod 92 with the clamp 94. The bracket 99 is a T-shaped structure welded from two sections of square steel tubes. The horizontal square steel tube is used to slide and insert the clamp 94, and the clamp 94 is tightened with a tightening screw. The vertical square steel tube is inserted into the slow-speed stirring impeller slot 15 of the movable impeller base 1 and tightened with a tightening screw 16 to restrict its vertical movement. In this embodiment, the slow stirring paddle 9 is installed in the slow stirring paddle slot 15 of the movable paddle holder 1 through a square steel tube in the vertical direction of the bracket 99, and is tightened by the tightening screw 16 to restrict its up and down movement.

[0065] During implementation, the bottom impeller 91, stirring rod 92, and side impeller 93 of the slow-speed stirring paddle 9 all extend into the inner tank 5 and contact the slurry. They remain stationary relative to the slurry, thus serving to stir it. Adjusting the insertion depth of the clamp 94 into the horizontal steel pipe of the support 99 adjusts the distance between the stirring rod 92 and the side impeller 93 and the inner tank wall 52. Rotating the stirring rod 92 within the circular hole of the clamp 94 adjusts the angle of the bottom impeller 91 inside the inner tank 5; moving the stirring rod 92 up and down within the circular hole of the clamp 94 adjusts the distance between the bottom impeller 91 and the bottom 54 of the inner tank 5.

[0066] In one specific embodiment of this utility model, it further includes: a temperature detection system 8; the temperature detection system 8 is used to detect the temperature change of the slurry during the stirring process. Specifically, as shown... Figure 10As shown, the temperature detection system 8 consists of a mounting plate 81 and a temperature sensor 82. The mounting plate 81 is installed on the reinforcing ring 44 on the outer barrel of the outer barrel 4. The temperature sensor 82 is installed on the mounting plate 81, with its lower sensing rod extending into the inner barrel 5. The temperature detection system 8 detects the temperature changes of the slurry during the stirring process by extending the lower sensing rod of the temperature sensor 82 into the inner barrel 5. The temperature sensor 82 feeds back the measured temperature value to the control system 3. When the slurry temperature exceeds the preset temperature range, the control system 3 sends a signal to allow the cooling water from the cooling system 6 to enter the stirring rod 92. The stirring rod 92 contacts the slurry, cooling it down. When the slurry temperature returns to the preset temperature range, the temperature sensor 82 feeds back the measured temperature value to the control system 3, and the control system 3 sends a signal to shut down the cooling system 6, ending the cooling process.

[0067] In one specific embodiment of this utility model, such as Figure 11 As shown, the cooling system 6 includes: an inlet hose 67, an outlet hose 68, and an inlet pipe 97 and an outlet pipe 96 mounted on the stirring rod 92; the inlet hose 67 is connected to the inlet pipe 97, and the outlet hose 68 is connected to the outlet pipe 96; the stirring rod 92 has a hollow internal structure and is closed at both ends, and the outlet pipe 96 and the inlet pipe 97 communicate with the internal cavity of the stirring rod 92. Specifically, the outlet pipe 96 and the inlet pipe 97 are installed at the upper end of the stirring rod 92, and the lower end is welded to the bottom impeller 91. The outlet pipe 96 is an L-shaped bend, with one end installed at the upper end of the stirring rod 92, and the other end connected to the outlet hose 68 of the cooling system 6 via a quick-connect elbow 98. The inlet pipe 97 is an L-shaped bend, with one end installed at the upper end of the stirring rod 92, and the other end connected to the inlet hose 67 of the cooling system 6 via a quick-connect elbow 98.

[0068] Furthermore, the cooling system 6 also includes: an inlet ball valve 61, an outlet ball valve 62, a solenoid valve 63, an inlet rigid pipe 64, an outlet rigid pipe 65, and a quick-connect elbow 66.

The solenoid valve 63 is installed on the inlet rigid pipe 64 and is used to open and close the cooling system. There are two quick-connect elbows 66, which connect the inlet rigid pipe 64 and the inlet hose 67, and the outlet rigid pipe 65 and the outlet hose 68, respectively. One end of the inlet hose 67 is connected to the inlet rigid pipe 64 via the quick-connect elbow 66, and the other end is connected to the inlet quick-connect elbow 98 of the slow-speed agitator 9. One end of the outlet hose 68 is connected to the outlet rigid pipe 65 via the quick-connect elbow 66, and the other end is connected to the outlet quick-connect elbow 98 of the slow-speed agitator 9. The cooling system 6 is installed on the cooling system mounting base 41 of the outer barrel 4. It is connected to the inlet pipe 97 and outlet pipe 96 of the slow-speed stirring paddle 9 through the inlet hose 67 and outlet hose 68. During cooling: the cooling water enters from the inlet ball valve 61 of the cooling system 6, and flows through the solenoid valve 63 in sequence through the inlet hard pipe 64, inlet hose 67, inlet pipe 97, stirring rod 92, outlet pipe 96, outlet hose 68, outlet hard pipe 65 and outlet ball valve 62, forming a series cooling water flow loop. The cooling water comes into contact with the slurry through the stirring rod 92 of the slow-speed stirring paddle 9, and carries away the heat generated by the slurry during the rotation and stirring process, so as to avoid the slurry temperature rising too much and affecting the slurry performance and the subsequent coating effect.

[0069] In one specific embodiment of this utility model, the pulping equipment further includes a control system 3; the control system 3 is used to control the start / stop and speed of the geared motor 21 and the motor 705. Specifically, the control system 3 is used to realize the power supply and control of the entire equipment. The control system 3 integrates cables and electrical control components. After power is applied, the rotation of the geared motor 21 and the motor 705 of the high-speed stirring paddle 7 can be controlled by operating buttons. The use of a control system to control the start / stop and speed of multiple motors in this embodiment is within the scope of what those skilled in the art can achieve, and the detailed structure and control principle of the control system will not be described in detail in this embodiment.

[0070] The specific usage method of this pulping equipment is as follows:

[0071] 1) When using the equipment, first manually operate the first handle 18 on the movable slurry tank seat 1 to push the entire equipment next to the slurry tank.

[0072] 2) Pour the materials for making the slurry into the inner bucket 5.

[0073] 3) Connect the external cooling water inlet pipe to the inlet ball valve 61 of the cooling system 6, connect the external cooling water outlet pipe to the outlet ball valve 62 of the cooling system 6, and open the inlet ball valve 61 and the outlet ball valve 62.

[0074] 4) Connect the power supply, operate the control system 3, start the geared motor 21 of the transmission system 2, the geared motor 21 rotates and drives the inner barrel 5 to rotate, and the slurry follows the inner barrel 5 to rotate slowly.

[0075] 5) Operation control system 3: Start motor 705 of high-speed agitator 7. Motor 705 rotates, driving impeller shaft 702 and impeller 701 to rotate, thus agitating the slurry. At the same time, due to the rotation of inner tank 5, inner tank 5 and its internal slurry are in a state of relative rotation with slow agitator 9, so that the internal slurry can converge towards the center under the disturbance of slow agitator 9, realizing that the slurry is in a state of overall circulation being agitated by high-speed agitator 7.

[0076] 6) When the slurry temperature exceeds the preset temperature range, the solenoid valve 63 of the cooling system 6 automatically opens, and cooling water enters the stirring rod 92 to cool the slurry. When the slurry temperature returns to the preset temperature range, the solenoid valve 63 of the cooling system 6 automatically closes.

[0077] 7) After a certain period of time, once the slurry is prepared, turn off the power. The reduction motor 21 and motor 705 will stop rotating, and the slurry will be transported into the slurry dipping tank.

[0078] 8) Disconnect the external cooling water inlet pipe from the inlet ball valve 61 of the cooling system 6, disconnect the external cooling water outlet pipe from the outlet ball valve 62 of the cooling system 6, and close the inlet ball valve 61 and the outlet ball valve 62.

[0079] 9) Push the pulping equipment away from the pulping tank.

[0080] It is worth noting that "high speed" and "slow speed" in this utility model refer to the relative speed of the two stirring paddles in the stirring state, and do not represent specific speed values. The specific speed of the two stirring paddles can be set according to actual needs.

[0081] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
