Description

Technical Field

[0001] This utility model relates to the field of refractory material processing technology, specifically to a refractory material raw material cleaning device. Background Technology

[0002] Refractory material raw material cleaning equipment is mainly used to remove impurities from raw materials to improve their purity and the performance stability of the final product. This equipment typically consists of a crushing and pre-screening unit, a water washing or acid washing unit, a dehydration and drying unit, and a wastewater treatment system. During cleaning, the raw material is first coarsely screened through a vibrating screen or drum screen to remove large impurities. It then enters a stirred water washing tank or spray system, where water jets dissolve surface deposits. If necessary, dilute acid is added to remove metal oxides. After dehydration by a centrifuge or filter press, the washed raw material is sent to a rotary kiln or fluidized bed dryer to remove moisture, ultimately obtaining clean raw material.

[0003] For example, the patent with authorization announcement number CN217191288U discloses a raw material cleaning device for refractory material production. By setting up a cleaning mechanism, the device uses centrifugal force to clean the raw materials, thus improving the cleaning effect. By setting up a filtration mechanism, it can filter impurities in wastewater, which can effectively reduce environmental pollution. However, there are still some shortcomings.

[0004] To prevent material from being thrown out during centrifugation, workers need to use fixing bolts to connect and fix the first mounting plate to the fixing block to seal the top of the placement cylinder. After centrifugation, the bolts need to be rotated in the opposite direction to remove them. Since there are multiple bolts, the assembly and disassembly efficiency is low, which delays the cleaning time and reduces the overall cleaning efficiency of the material.

[0005] Therefore, a refractory material raw material cleaning device is provided to address the above-mentioned problems. Utility Model Content

[0006] This invention provides a refractory material raw material cleaning device to solve the problem that sealing the top of the placement cylinder with bolts affects the cleaning efficiency.

[0007] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0008] This utility model provides a refractory material raw material cleaning device, including a cleaning chamber for cleaning and dehydration. The bottom of the cleaning chamber is fixedly installed with the output end of a centrifugal motor, and the top of the cleaning chamber is movably installed with an inner cover plate for sealing the top. Multiple clearance holes are opened through the outer side of the cleaning chamber, and multiple locking holes are opened through the outer side of the inner cover plate. The locking holes correspond one-to-one with the clearance holes.

[0009] A locking pin is slidably installed inside the clearance hole. Under the centrifugal force, the locking pin slides into the locking clearance hole to form a self-locking mechanism, which fixes the cleaning chamber and the inner cover plate.

[0010] A large end plate is fixedly installed at one end of the locking pin near the cleaning chamber. A return spring is fixedly installed between the large end plate and the cleaning chamber. The return spring is movably sleeved around the locking pin. When the centrifugal force weakens, the return spring drives the locking pin to return to its original position, and the cleaning chamber and inner cover plate are no longer locked.

[0011] Preferably, the inner cover plate has multiple limiting grooves on its inner side, and multiple snap-fit ​​blocks are fixedly installed on the outer side of the cleaning chamber, with the snap-fit ​​blocks movably installed inside the limiting grooves.

[0012] Preferably, a housing is rotatably mounted around the cleaning chamber, and the output end of the centrifugal motor rotates through the bottom of the housing.

[0013] Preferably, an outer cover plate is movably installed on the top of the housing, and lifting hooks are fixedly installed on the top of both the outer cover plate and the inner cover plate.

[0014] Preferably, a drain pipe is fixedly installed on the outer side of the housing, and an electric valve is fixedly installed in the middle of the drain pipe.

[0015] Preferably, a plurality of support columns are fixedly installed at the bottom of the housing.

[0016] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0017] The positive and progressive effects of this utility model are as follows:

[0018] During dehydration, the locking pin is inserted into the locking through hole under the action of centrifugal force, which fixes the cleaning chamber and the inner cover plate, preventing the material from being thrown out of the cleaning chamber. After dehydration, the locking pin is reset under the elastic force of the return spring, and the fixed connection between the cleaning chamber and the inner cover plate is automatically released. That is, the cleaning chamber and the inner cover plate are automatically locked when rotating and automatically released when stationary, eliminating the need for staff to fix or disassemble them, reducing labor intensity and improving cleaning efficiency.

[0026] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0027] like Figure 1-5 As shown, the refractory material raw material cleaning device includes a cleaning chamber 7 for cleaning and dehydration. The output end of a centrifugal motor 6 is fixedly installed at the bottom of the cleaning chamber 7. An inner cover plate 8 for sealing the top of the cleaning chamber 7 is movably installed at the top of the cleaning chamber 7. Multiple clearance holes 11 are opened through the outer side of the cleaning chamber 7. Multiple locking holes 10 are opened through the outer side of the inner cover plate 8. The locking holes 10 correspond one-to-one with the clearance holes 11.

[0028] A locking pin 12 is slidably installed inside the clearance through hole 11. Under the centrifugal force, the locking pin 12 slides into the locking through hole 10 to form a self-locking mechanism, which fixes the cleaning chamber 7 and the inner cover plate 8.

[0029] A large end plate 14 is fixedly installed at one end of the locking post 12 near the cleaning chamber 7. A return spring 13 is fixedly installed between the large end plate 14 and the cleaning chamber 7. The return spring 13 is movably sleeved around the locking post 12. When the centrifugal force weakens, the return spring 13 drives the locking post 12 to return to its original position, and the cleaning chamber 7 and the inner cover plate 8 are no longer locked.

[0030] Specifically, a housing 1 is rotatably mounted around the cleaning chamber 7 to hold clean water or a specific solution, and the output end of the centrifugal motor 6 rotates through the bottom of the housing 1.

[0031] Specifically, an outer cover plate 2 is movably installed on the top of the housing 1 to seal the top of the housing 1 and prevent external interference with the cleaning operation. Lifting hooks 3 are fixedly installed on the top of both the outer cover plate 2 and the inner cover plate 8 to facilitate the movement of workers.

[0032] In this embodiment, the material is added to the cleaning chamber 7, and clean water or other required solutions are added to the shell 1. The inner cover plate 8 is placed on top of the cleaning chamber 7, and the limiting groove 9 and the snap-fit ​​block 16 are inserted and matched. The outer cover plate 2 is placed on top of the shell 1, and the centrifugal motor 6 rotates back and forth, driving the cleaning chamber 7 to rotate back and forth to clean the material.

[0033] Specifically, a drain pipe 4 for discharging cleaning wastewater is fixedly installed on the outer side of the housing 1, and an electric valve 5 is fixedly installed in the middle of the drain pipe 4 to facilitate the opening and closing of the drain pipe 4 by the staff.

[0034] In this embodiment, after the cleaning is completed, the electric valve 5 is opened, the sewage flows out from the drain pipe 4, the centrifugal motor 6 rotates at high speed, driving the cleaning chamber 7 and the material to rotate at high speed to dehydrate, the locking column 12 and the large end plate 14 increase in speed and centrifugal force, the reset spring 13 is compressed, the locking column 12 is inserted into the locking through hole 10, and the cleaning chamber 7 and the inner cover plate 8 are fixed, so that the material will not be thrown away from the cleaning chamber 7.

[0035] After dehydration, the centrifugal motor 6 stops rotating, the locking column 12 and the large end plate 14 reduce their speed and centrifugal force, and the locking column 12 resets under the elastic force of the return spring 13. The fixed connection between the cleaning chamber 7 and the inner cover plate 8 is automatically released. Subsequently, the staff can directly remove the outer cover plate 2 and the inner cover plate 8 to take out the material. The cleaning chamber 7 and the inner cover plate 8 automatically lock when rotating and automatically unlock when stationary, eliminating the need for staff to fix or disassemble them, reducing labor intensity and improving cleaning efficiency.

[0036] Specifically, a plurality of support columns 15 are fixedly installed at the bottom of the housing 1 to maintain the stable placement of the housing 1.

[0037] Specifically, the inner cover plate 8 has multiple limiting grooves 9 on its inner side, and multiple snap-fit ​​blocks 16 are fixedly installed on the outer side of the cleaning chamber 7. The snap-fit ​​blocks 16 are movably installed inside the limiting grooves 9. The snap-fit ​​blocks 16 and the limiting grooves 9 cooperate to align the clearance through hole 11 and the locking through hole 10, so that they can be aligned without the need for staff to rotate them, and no misalignment will occur during subsequent rotation.
