Description

Technical Field

[0001] The invention relates to the technical field of driving and guiding flow of a rock wool centrifuge, in particular to a guiding and driving device applied to a rock wool production centrifuge. Background Art

[0002] In the process of rock wool production, the centrifuge is one of the most important equipment. The rock wool centrifuge is specially used to make building rock wool boards. Its function is to spray or spray the melted or heated basalt or quartz sand and other raw materials in the high-speed rotating centrifuge, and turn the raw materials into refined fibers through centrifugal force and high temperature.

[0003] However, the traditional rock wool centrifuge adopts belt drive or direct motor drive. This driving method has a simple structure and a single function. After a long period of rotation, it not only transmits power, but also transfers the vibration of the equipment to the drive end. This causes the connection mechanism at the drive end to easily resonate, seriously affecting the service life of the equipment, resulting in high maintenance costs and difficulties in the later stage. At the same time, under the action of centrifugal rotation, the glue needs to be transported inward synchronously, and the traditional transportation method is only through lateral extrusion, resulting in low transportation efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the traditional driving method cannot completely isolate vibration, resulting in a short service life of the driving unit, great difficulty and high cost in subsequent maintenance, and low efficiency in glue liquid delivery.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a flow guide drive device applied to a rock wool production centrifuge, comprising a transverse drive shaft tube for installing a rotating roller of the centrifuge and a liquid storage tank with a drive pump arranged inside, an outer drive shaft tube is axially fixed to the outer end of the transverse drive shaft tube, an external flow guide shaft cylinder is movably sleeved on the outer periphery of the outer drive shaft tube on the transverse drive shaft tube, a plurality of external flow guide tubes are provided on the outer side surface of the external flow guide shaft cylinder, an annular drive groove with built-in centrifugal drive blades is provided on the outer arc surface of the outer drive shaft tube, a central flow guide tube hole with a conical structure is provided on the inner side surface of the transverse drive shaft tube, and internal centrifugal blades are provided on the inner side surface of the central flow guide tube hole.

[0006] The external flow guide pipe comprises an inlet pipe and a return pipe fixed on the outer side of the external flow guide shaft cylinder, and the inlet pipe and the return pipe are arranged in a staggered and reverse manner.

[0007] The liquid outlet of the driving pump is connected to the inlet pipe through the first external flow guide pipe, and the return port of the liquid storage tank is connected to the return pipe through the second external flow guide pipe.

[0008] An external installation box is fixedly mounted on the outside of the external flow guide shaft cylinder, and the bottom side wall of the external installation box is connected with the inside of the liquid storage tank through an external return pipe.

[0009] An electrically controlled regulating valve is installed between the connecting end of the inlet pipe and the first external flow guiding pipe and between the connecting end of the return pipe and the second external flow guiding pipe.

[0010] The outer connecting surface between the external installation box and the external guide shaft cylinder is fixedly equipped with a rubber shock-absorbing pad, and the outer side surface of the external installation box is installed with a lateral support stabilizing frame.

[0011] A replaceable metal filter screen is fixedly mounted inside the external installation box.

[0012] The outer side ends of the transverse drive shaft tubes are provided with lateral mounting slots, and the outer side drive shaft tubes are slidably sleeved on the lateral mounting slots to be fixedly connected with the transverse drive shaft tube.

[0013] The height of the internal centrifugal blades on the inner side of the central guide pipe hole gradually increases from right to left.

[0014] The upper end of the external installation box is fixedly assembled with a lateral sealing cover shell through a bottom guide tube, and the external installation box is fixedly assembled with both sides of the external guide shaft cylinder through the lateral sealing cover shell.

[0015] The beneficial effects of the present invention are:

[0016] (1) The flow guide drive device used in the rock wool production centrifuge of the present invention controls the horizontal drive shaft tube by using a fluid drive method, and does not directly connect the horizontal drive shaft tube to the hard connection, thereby avoiding vibration transmission and prolonging the service life of the drive device;

[0017] (2) By adopting an external guide pipe consisting of an inlet pipe and a return pipe, the external guide pipe is arranged in a reverse manner on the outer surface of the external guide shaft cylinder, which is fixed on the outer surface of the external guide shaft cylinder, so that the assembly can be facilitated, the guide resistance can be reduced, and the driving efficiency can be improved;

[0018] (3) The number of openings and closings of the inlet and return pipes can be freely started as needed, thereby adjusting the amount of liquid inflow, greatly improving the speed and torque of the transverse drive shaft tube, and making control more convenient;

[0019] (4) By adopting the external guide shaft tube design, it can not only cooperate with the horizontal drive shaft tube to drive, but also improve the sealing of its transmission end to ensure driving efficiency;

[0020] (5) By fixing the external mounting box on the outside of the external guide shaft, the sealing effect on both sides can be improved, and once leakage occurs, the leakage can be quickly diverted;

[0021] (6) The entire equipment adopts an external structure design, which can be easily installed and disassembled for maintenance;

[0022] (7) A central guide pipe hole with a conical structure is opened on the inner side of the transverse drive shaft tube, and an internal centrifugal blade is provided on the inner side of the central guide pipe hole. The internal glue liquid can be thrown out through the centrifugal force during the rotation process and the conical guide channel design, thereby improving the guide effect.

[0030] Figure 1 , Figure 2 , Figure 3 and Figure 4The shown device is a flow guide drive device for a rock wool production centrifuge, comprising a transverse drive shaft tube 1 for installing a rotating roller of the centrifuge and a liquid storage tank 3 with a drive pump 2 placed inside. An outer drive shaft tube 4 is axially fixed to the outer end of the transverse drive shaft tube 1. An external flow guide shaft cylinder 5 is movably sleeved on the outer periphery of the outer drive shaft tube 4 on the transverse drive shaft tube 1. Six external flow guide tubes 6 are arranged on the outer surface of the external flow guide shaft cylinder 5. An annular drive groove 8 with built-in centrifugal drive blades 7 is provided on the outer arc surface of the outer drive shaft tube 4. A central flow guide pipe hole 9 with a conical structure is provided on the inner side surface of the transverse drive shaft tube 1, and internal centrifugal blades 10 are provided on the inner side surface of the central flow guide pipe hole 9.

[0031] Working principle: the driving pump 2 rotates at high speed, and then is introduced into the external guide shaft tube 5 through the external guide tube 6, driving the outer drive shaft tube 4 to rotate at high speed, and then controlling the horizontal drive shaft tube 1 to rotate, and then while the horizontal drive shaft tube 1 rotates at high speed, the internal centrifugal blades 10 are driven to rotate, the glue is drawn in from the outside, and then thrown out from the side of the rotating roller of the centrifuge.

[0032] In order to coordinate the lateral arrangement and flow diversion, the external flow diversion pipe 6 includes an inlet pipe 61 and a return pipe 62 fixed on the outer side of the external flow diversion shaft cylinder 5, and the inlet pipe 61 and the return pipe 62 are arranged in an offset and reverse manner.

[0033] The inlet pipe 61 and the return pipe 62 are respectively fixed on both sides of the outer arc surface of the external guide shaft cylinder 5, and then fixed on the outside of the external guide shaft cylinder 5 in a circular array. The directions of the inlet pipe 61 and the return pipe 62 are exactly opposite, which can greatly reduce the resistance of the inlet and return flow, thereby improving the efficiency. At the same time, the inlet pipe 61 and the return pipe 62 are arranged on both sides, which can also avoid mutual influence when connecting the guide pipes.

[0034] In order to cooperate with external communication and diversion, the liquid outlet of the driving pump 2 is connected to the inlet pipe 61 through the first external diversion pipe 111, and the reflux port of the liquid storage tank 3 is connected to the reflux pipe 62 through the second external diversion pipe 121.

[0035] The driving pump 2 is started, and then the driving liquid inside the liquid storage tank 3 is introduced into the inlet pipe 61 through the first external guide pipe 111, and then introduced into the annular driving groove 8 through the inlet pipe 61, driving the centrifugal driving blades 7, controlling the outer driving shaft tube 4 to rotate, and then driving the horizontal driving shaft tube 1 to rotate at high speed, and then refluxes from the return pipe 62 through the second external guide pipe 121 to the inside of the liquid storage tank 3.

[0036] In order to store and return the overflow liquid, an external installation box 12 is fixedly mounted on the outside of the external guide shaft cylinder 5 , and the bottom side wall of the external installation box 12 is connected to the inside of the liquid storage tank 3 through an external return pipe 13 .

[0038] The electronically controlled regulating valve 14 regulates the connection state between the inlet pipe 61 and the connection end of the first external flow guiding pipe 111 and between the return pipe 62 and the connection end of the second external flow guiding pipe 121 by controlling opening and closing.

[0039] In order to reduce the shock absorption and lateral support stability of the connection end, a rubber shock-absorbing pad 15 is fixedly installed on the outer connecting surface of the external installation box 12 and the external guide shaft tube 5, and a lateral support stabilizing frame 16 is installed on the outer side surface of the external installation box 12.

[0040] The lateral support stabilizing frame 16 supports and fixes the adjacent external installation box 12 by being fixed on the outer side surface of the external installation box 12. The lateral support stabilizing frame 16 adopts a non-rigid structure design, which can reduce vibration to a certain extent.

[0041] In order to filter the internal liquid, a replaceable metal filter screen 17 is fixedly installed inside the external installation box 12 .

[0042] When liquid leaks from the outside of the external guide shaft cylinder 5 , the liquid will first flow into the outside installation box 12 , and then be filtered by the replaceable metal filter 17 , and then flow back into the liquid storage tank 3 .

[0043] In order to facilitate loading and unloading and fixing, a lateral mounting groove is provided at the outer end of the transverse drive shaft tube 1, and the outer drive shaft tube 4 is fixedly connected to the transverse drive shaft tube 1 by slidingly sleeved on the lateral mounting groove.

[0044] In order to cooperate with the internal flow guidance, the height of the internal centrifugal blades 10 on the inner side of the central flow guidance pipe hole 9 gradually increases from right to left.

[0045] In order to cooperate with the lateral assembly, the upper end of the external installation box 12 is fixedly assembled with a lateral sealing cover 19 through the bottom guide tube 18, and the external installation box 12 is fixedly assembled with both sides of the external guide shaft tube 5 through the lateral sealing cover 19.

[0046] The bottom of the lateral sealing cover 19 is fixedly connected to the interior of the external mounting box 12 through the bottom guide pipe 18, and then the lateral sealing cover 19 is fixedly assembled with the two side walls of the external mounting box 12. Circular assembly through holes matching the horizontal drive shaft tube 1 are opened inside the lateral sealing covers 19 on both sides, and a glue storage box for storing glue is fixed on the side wall of the outer lateral sealing cover 19. Then the liquid storage box is fixed on the outer side surface of the lateral sealing cover 19 through the bottom arc-shaped material guide pipe and is connected to the interior of the horizontal drive shaft tube 1. A regulating valve is arranged in the bottom arc-shaped material guide pipe to control the liquid output from the bottom of the glue storage box.
