Description

Technical Field

[0001] The invention relates to the technical field of refractory castable processing. Background Art

[0002] Refractory castables are a kind of granular and powdery materials made of refractory materials with a certain amount of binder. They have high fluidity and are amorphous refractory materials formed by pouring. Compared with other amorphous refractory materials, they have higher binder and moisture content and better fluidity. Therefore, castables have a wide range of applications. The materials and binders used can be selected according to the conditions of use. They can be directly cast into linings for use, or made into prefabricated blocks by pouring or vibrating.

[0003] In the existing technical scheme, during the mixing and stirring of refractory castables, the raw materials need to be poured into the mixer first, and then sufficient clean water is gradually added for mixing. In order to ensure the quality of the finished castable, the amount of clean water to be added during the mixing process needs to be strictly controlled. Usually, the castable is tested through a consistency test after stirring to determine whether the castable is in the optimal consistency. Therefore, during the stirring of refractory castables, it is particularly important to reasonably control the amount of water added. However, when using, if the water is added in small portions, it will affect the overall construction efficiency. If a large amount of clean water is poured directly, it is difficult to accurately control the amount of water added. Therefore, a mixing equipment is needed that can ensure construction efficiency while facilitating the control of the amount of water added. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a refractory castable mixing device and a use method thereof which are convenient for controlling the amount of water added, and can regulate the amount of water added while ensuring the construction efficiency.

[0006] An annular groove is provided at the top of the mixing barrel, and the supporting mechanism includes an arc-shaped sliding block slidably arranged in the annular groove and a connecting plate fixedly connected to the top of the arc-shaped sliding block, the connecting plate is slidably fitted with the top of the mixing barrel, and the top of the connecting plate is fixedly connected to a connecting rod inclined upward near the center of the mixing barrel, and the top of the connecting rod is detachably connected to the water tank.

A large amount of water is first poured into the second water storage chamber, and then water is slowly added to the first water storage chamber, which facilitates the regulation of the amount of water added during the stirring process while ensuring the construction efficiency; when in use, the arc-shaped slider rotates in the annular groove to remain stable, and the connecting plate is mounted on the top of the mixing barrel, which can provide stable support for the water storage tank.

[0008] Based on the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the volume ratio of the first water storage chamber to the second water storage chamber is 2:8.

[0011] The beneficial effect of adopting the above further scheme is that when in use, the castable is mixed and stirred by rotating the stirring frame. At the same time, the stirring frame can drive the water tank to rotate slowly, so that the water flowing out of the water tank can flow out more evenly, which is convenient for rapid mixing and stirring.

[0014] Furthermore, the two sealing baffles separate the interior of the water tank into a cavity for installing a vibration mechanism and a telescopic component. The vibration end of the vibration mechanism can extend into the mixing barrel through the telescopic component to contact the castable. The mixing barrel is provided with a visual observation window for observing the position of the castable and the vibration end of the vibration mechanism.

[0017] The beneficial effect of adopting the above further scheme is that the lifting and lowering movement of the telescopic end of the electric telescopic rod drives the lifting and lowering movement of the vibrating rod head, so that the vibrating rod head can stably move in and out of the castable, which is convenient for detecting the amount of water added to the castable.

[0018] Furthermore, a through hole is vertically opened on the water storage tank, an elastic ring is fixedly installed in the through hole, and the vibrating rod head can be slidably arranged in the elastic ring.

[0035] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0036] like Figure 1-3 As shown, a refractory castable mixing device and a method of using the same are provided in Example 1, comprising a mixing barrel 1 and a mixing mechanism arranged on the mixing barrel 1, a water storage tank 2 with an open top is arranged above the mixing barrel 1, two sealing baffles 25 are vertically arranged in the water storage tank 2 to divide the interior of the water storage tank 2 into a first water storage chamber 21 and a second water storage chamber 22 which are horizontally spaced, the volume of the first water storage chamber 21 is smaller than the volume of the second water storage chamber 22, the first water storage chamber 21 and the second water storage chamber 22 are both provided with connecting pipes, the two connecting pipes are connected through a first valve 24, the bottom end of the water storage tank 2 is connected with two water outlet pipes extending into the mixing barrel 1, the two water outlet pipes are respectively connected with a second valve 26 and a third valve 27, the second valve 26 and the third valve 27 correspond to and are connected with the first water storage chamber 21 and the second water storage chamber 22 respectively, and the clean water in the inner cavity of the first water storage chamber 21 will flow into the inner cavity of the mixing barrel 1 in small streams.

[0037] With the above structure, after the raw materials are added into the inner cavity of the mixing barrel 1, an appropriate amount of clean water is introduced into the inner cavity of the water storage tank 2 according to the amount of the raw materials, and the first valve 24 is opened. The first valve 24 is opened to connect the first water storage chamber 21 and the second water storage chamber 22, and the liquid level height of the water in the inner cavity of the first water storage chamber 21 and the second water storage chamber 22 is kept consistent. At this time, the amount of water stored in the inner cavity of the first water storage chamber 21 and the second water storage chamber 22 is consistent with the ratio of the space occupied by the first water storage chamber 21 and the second water storage chamber 22 in the water storage tank 2. Closing the first valve 24 and directly opening the third valve 27 can quickly pour the clean water in the inner cavity of the second water storage chamber 22 into the inner cavity of the mixing barrel 1, and the water in the inner cavity of the first water storage chamber 21 flows into the mixing barrel 1 in small amounts through the second valve 26, which is convenient for controlling the amount of water added while ensuring construction efficiency.

[0038] In this embodiment, Figure 3 As shown, the volume ratio of the first water storage chamber 21 to the volume ratio of the second water storage chamber 22 is 2:8. With the above structure, the ratio of the water in the first water storage chamber 21 to the water in the second water storage chamber 22 is 2:8, the water in the second water storage chamber 22 can ensure the wet mixing of the castable, and the water in the first water storage chamber 21 can play a role in controlling the water volume.

[0039] In this embodiment, Figure 2 As shown, the stirring mechanism includes a driving motor 12 fixedly connected to the bottom end of the stirring barrel 1 and a stirring frame 13 rotatably arranged in the stirring barrel 1, the output shaft of the driving motor 12 is arranged vertically upward, the bottom end of the stirring frame 13 vertically penetrates the bottom wall of the stirring barrel 1 and is coaxially connected to the output shaft of the driving motor 12, the top end of the stirring frame 13 is fixedly connected with a spline shaft 131, the bottom end of the water tank 2 is fixedly connected with a spline sleeve corresponding to the spline shaft 131, the spline shaft 131 can be inserted into the spline sleeve, and the bottom end of the water tank 2 is detachably installed with a supporting mechanism 15, and the supporting mechanism 15 is slidably arranged on the top end of the stirring barrel 1. With the above structure, the driving motor 12 rotates to drive the stirring frame 13 to rotate, and the stirring frame 13 drives the water tank 2 to rotate synchronously through the spline shaft 131. The support mechanism 15 slides on the top of the stirring barrel 1. The support mechanism 15 can provide a certain supporting force for the fixation of the water tank 2. When rotating, the clean water flowing out of the third valve 27 and the second valve 26 will follow the rotation of the water tank 2 and flow into the inner cavity of the stirring barrel 1, thereby ensuring the uniformity of water addition.

[0040] In this embodiment, Figure 2As shown, an annular groove 14 is provided at the top of the mixing barrel 1, and the supporting mechanism 15 includes an arc-shaped slider 151 slidably disposed in the annular groove 14 and a connecting plate 152 fixedly connected to the top of the arc-shaped slider 151. The connecting plate 152 is slidably fitted with the top of the mixing barrel 1, and a connecting rod 153 is fixedly connected to the top of the connecting plate 152 and is tilted upward near the center of the mixing barrel 1. The top of the connecting rod 153 is detachably connected to the water storage tank 2. With the above structure, the arc-shaped slider 151 is inserted into the annular groove 14 and rotates along the center of the mixing barrel 1 in the annular groove 14. The bottom end of the connecting plate 152 is connected to the top of the mixing barrel 1. The contact between the connecting plate 152 and the mixing barrel 1 provides a certain supporting force for the connecting plate 152, thereby ensuring the stability of the water storage tank 2 during the movement process.

[0041] In this embodiment, Figure 6 As shown, the top of the connecting rod 153 is vertically connected to a connecting tube 155 with an opening at the top. The connecting tube 155 passes through the bottom end of the water storage tank 2 and extends to the top of the bottom wall of the water storage tank 2. The inner wall of the connecting tube 155 is provided with an internal thread, and a bolt 154 is connected to the threaded hole. The connecting tube 155 is threadedly connected to the water storage tank 2 through the bolt 154, and the bottom end of the connecting tube 155 is fixedly connected to a support block located below the water storage tank 2. With the above structure, the connecting rod 153 is passed through the bottom end of the water storage tank 2, and the bolt 154 is rotated into the connecting tube 155, so that the water storage tank 2 and the support mechanism 15 are stably fixed. When the water storage tank 2 needs to be removed and placed, it is only necessary to separate the bolt 154 and the connecting tube 155. The inclined connecting plate 152 can better ensure the stable support of the water storage tank 2.

[0042] In this embodiment, Figure 3 and Figure 5 As shown, two sealing baffles 25 separate the interior of the water tank 2 into a cavity for installing the vibration mechanism 23 and the telescopic assembly. The vibration end of the vibration mechanism 23 can extend into the mixing barrel 1 through the telescopic assembly to contact the castable material. The mixing barrel 1 is provided with a visual observation window 11 for observing the position of the castable material and the vibration end of the vibration mechanism 23.

[0043] Furthermore, the vibration mechanism 23 includes a driver 231 fixedly mounted on the bottom wall of the water storage tank 2 and a vibrating rod head 232 connected to the driver 231. The telescopic assembly includes an electric telescopic rod 28 fixedly mounted on the bottom wall of the water storage tank 2. The telescopic end of the electric telescopic rod 28 is vertically telescopic. The telescopic end of the electric telescopic rod 28 is fixedly connected to the vibrating rod head 232 through a rod. The vibrating rod head 232 can move into the casting material in the inner cavity of the mixing barrel 1. With the above structure, the movement of the telescopic end of the electric telescopic rod 28 drives the vibrating rod head 232 to move. When the vibrating rod head 232 moves into the casting material, the driver 231 starts to control the vibration of the vibrating rod head 232. The staff can directly observe the vibration process through the visual viewing window 11 to judge the amount of water added during the mixing process of the casting material without taking out the casting material for judgment.

[0044] In this embodiment, Figure 5 As shown, a through hole is vertically opened on the water storage tank 2, and an elastic ring is fixedly installed in the through hole, and the vibrating rod head 232 can be slidably arranged in the elastic ring. With the above structure, when the vibrating rod head 232 rises from the casting material, the vibrating rod head 232 rubs against the inside of the elastic ring, and the elastic ring scrapes off the casting material adhered to the vibrating rod head 232.

[0045] The steps of using a refractory castable mixing device are as follows:

[0046] S1. Pour the castable raw material into the inner cavity of the mixing barrel 1, pour clean water into the inner cavity of the second water storage cavity 22, open the first valve 24, and a part of the clean water in the inner cavity of the second water storage cavity 22 flows into the first water storage cavity 21 through the connecting pipe, and then close the first valve 24 to prevent the first water storage cavity 21 and the second water storage cavity 22 from being connected to each other;

[0047] S2, the driving motor 12 is started to drive the stirring frame 13 to rotate, the stirring frame 13 is started to dry mix the raw materials for 1-2 minutes, the third valve 27 is opened, and the clean water in the inner cavity of the second water storage chamber 22 flows into the inner cavity of the stirring barrel 1 through the outlet pipe connected thereto, and the stirring frame 13 mixes the castable raw materials with the clean water, and at the same time, the spline shaft 131 is inserted into the spline sleeve to drive the water storage tank 2 to move synchronously, and the clean water flowing out of the second water storage chamber 22 flows evenly into the inner cavity of the stirring barrel 1, and is stirred for 2-4 minutes;

[0048] S3, open the second valve 26, the clean water in the inner cavity of the first water storage chamber 21 will flow into the inner cavity of the mixing barrel 1 in small streams, and the stirring frame 13 continues to mix and stir the castable and the clean water for 1 minute;

[0049] S4, close the second valve 26, the telescopic end of the electric telescopic rod 28 descends to drive the vibrating rod head 232 to move downward in the through hole, the vibrating rod head 232 extends into the mixed castable, the driver 231 is started, the vibrating rod head 232 vibrates, and the vibration of the vibrating rod head 232 in the castable is observed through the visual viewing window 11. If water is accumulated, it means that the amount of water added to the castable is too high. Continue to add a certain amount of castable raw materials into the mixing barrel 1, and continue to vibrate until no water is left;

[0050] S5, turn off the driver 231, the vibrating rod head 232 stops vibrating, the telescopic end of the electric telescopic rod 28 moves upward to drive the vibrating rod head 232 to move upward, and observe through the visual viewing window 11 whether there are solidified holes in the castable. If there are solidified holes, it means that the amount of water added is too low, and return to step S3. If no obvious holes appear, it means that the castable has good fluidity, and go to step S6;

[0051] S6. Lift the water storage tank 2 upwards, remove the arc-shaped slider 151 from the annular groove 14, separate the water storage tank 2 and the mixing barrel 1, and take out the casting material in the inner cavity of the mixing barrel 1.

[0052] In the above method, through step S4 and step S5, the amount of water added during the mixing process can be determined without taking out the castable. The control of the amount of water added in step S1-step S3 can more accurately control the amount of water added while ensuring the overall construction efficiency.

S2, the driving motor (12) is started to drive the stirring frame (13) to rotate, the stirring frame (13) is started to dry mix the raw materials for 1-2 minutes, the third valve (27) is opened, the clean water in the inner cavity of the second water storage chamber (22) flows into the inner cavity of the stirring barrel (1) through the outlet pipe connected thereto, the stirring frame (13) mixes the castable raw materials with the clean water, and at the same time, the spline shaft (131) is inserted into the spline sleeve to drive the water storage tank (2) to move synchronously, and the clean water flowing out of the second water storage chamber (22) flows evenly into the inner cavity of the stirring barrel (1), and is stirred for 2-4 minutes; S3, opening the second valve (26), the clean water in the inner cavity of the first water storage chamber (21) will flow into the inner cavity of the mixing barrel (1) in small streams, and the stirring frame (13) will continue to mix and stir the castable and the clean water for 1 minute; S4, closing the second valve (26), the telescopic end of the electric telescopic rod (28) descends to drive the vibrating rod head (232) to move downward in the through hole, the vibrating rod head (232) extends into the mixed castable, the driver (231) is started, the vibrating rod head (232) vibrates, and the vibration of the vibrating rod head (232) in the castable is observed through the visual observation window (11). If water is accumulated, it means that the amount of water added to the castable is too high, and a certain amount of castable raw materials is continued to be added to the mixing barrel (1), and vibration is continued until no water is left; S5, turning off the driver (231), the vibrating rod head (232) stops vibrating, the telescopic end of the electric telescopic rod (28) moves upward to drive the vibrating rod head (232) to move upward, and observing through the visual viewing window (11) whether solidified holes appear in the castable. If solidified holes appear, it means that the amount of water added is too low, and the process returns to step S3. If no obvious holes appear, it means that the castable has good fluidity, and the process proceeds to step S6. S6. The water storage tank (2) is lifted upwards, and the arc-shaped slide block (151) is removed from the annular groove (14). The water storage tank (2) and the mixing barrel (1) are separated from each other, and the castable in the inner cavity of the mixing barrel (1) is removed.
