Description

Technical Field

[0001] This utility model relates to the technical field of adjusting base for tube bundle dryer, and particularly to an adjusting base for tube bundle dryer. Background Technology

[0002] Tube bundle dryers are indirect heating contact dryers. They utilize the principles of heat conduction and heat radiation to transfer heat from steam through the heat exchange tube walls to the material being dried on the other side. The material is stirred and pushed by shovels on the tubes, causing it to move from the feed end to the discharge end and be discharged through the discharge port. The vaporized moisture is discharged by a fan or naturally, thus completing the drying process.

[0003] Some existing tube bundle dryers may not be able to effectively achieve automatic and uniform lubrication of friction parts while simultaneously adjusting the axial displacement caused by the thermal expansion and contraction of the tubes with low resistance. In actual use, when using a sliding friction displacement structure, the frictional resistance is high, the expansion and contraction of the tubes are hindered, and long-term operation may easily cause severe wear of sliding parts. Manual lubrication not only requires frequent shutdowns, increasing the labor intensity and production interruption time, but is also prone to over- or under-lubrication due to differences in operator experience and inaccurate control of lubrication timing. Therefore, we propose an adjusting base for the tubes of a tube bundle dryer. Utility Model Content

[0004] The purpose of this utility model is to provide an adjusting base for tube bundle dryers, in order to solve the problem mentioned in the background art that it may not be possible to adjust the axial displacement caused by thermal expansion and contraction of the tube bundle with low resistance, while also effectively achieving automatic and uniform lubrication of the friction parts. In actual use, when a sliding friction displacement structure is used, the frictional resistance is large, the expansion and contraction of the tube bundle is hindered, and long-term operation may easily cause serious wear of the sliding parts. Manual lubrication not only requires frequent shutdown operations, increasing the labor intensity and production interruption time, but is also prone to problems such as over-lubrication or under-lubrication due to differences in operator experience and inaccurate control of lubrication timing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable base for a tube bundle dryer, comprising a dryer body and a frame. A steam inlet is provided on the front side of the dryer body. A tube bundle body is disposed inside the dryer body. Bearing seats are provided on both the front and rear sides of the bottom of the dryer body. The rear bearing seat is fixedly installed on the top of the frame. An adjustable base assembly is provided below the dryer body. The adjustable base assembly includes a small electric lubrication pump and a fixed seat. Another set of bearing seats is connected to rollers through a bearing sliding seat. The small electric lubrication pump is connected to an oil storage box through an oil extraction pipe. The small electric lubrication pump is connected to a main pipe and a branch pipe through an oil delivery pipe. Multiple sets of oil outlet holes distributed at equal intervals are provided on the outer wall of the branch pipe.

[0006] As a preferred embodiment, the bearing sliding seat is fixedly connected to the bottom of another set of bearing seats, the other set of bearing seats is located directly below the steam inlet end, the roller is disposed at the bottom of the bearing sliding seat, the fixed seat is fixedly installed on the top of the frame, the top of the fixed seat is provided with a slide rail, and the roller is rotatably connected to the inside of the slide rail.

[0007] As a preferred embodiment, the small electric lubrication pump is fixedly installed on the top of the frame, one end of the oil suction pipe is fixedly connected to the input end of the small electric lubrication pump, and the other end of the oil suction pipe is fixedly connected to the inside of the oil storage box. The oil storage box is fixedly installed on the top of the frame and located on the left side of the mounting base.

[0008] As a preferred embodiment, one end of the oil delivery pipe is fixedly connected to the output end of the small electric lubrication pump, the other end of the oil delivery pipe is fixedly connected to the inside of the main pipe, one end of the branch pipe is fixedly connected to the inside of the main pipe, and both the main pipe and the branch pipe are located inside the fixed base.

[0009] As a preferred embodiment, a collection assembly is provided on the outside of the fixed base. The collection assembly includes a solenoid valve tube, which is fixedly connected to the front surface of the fixed base. A support plate is provided directly below the solenoid valve tube, and the support plate is fixedly connected to the surface of the frame.

[0010] As a preferred embodiment, the top of the support plate is provided with a positioning groove, and an oil receiving box is provided inside the positioning groove. The oil receiving box is located directly below the solenoid valve pipe, and a filter screen is provided inside the oil receiving box.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the adjustable base assembly, the bearing seat below the steam inlet is connected to the roller via the bearing sliding seat. The roller rolls along the slide of the fixed seat, which can convert the axial displacement caused by the thermal expansion and contraction of the tube into low-resistance rolling motion. At the same time, for the rolling friction parts between the roller and the slide, a small electric lubrication pump can draw lubricating oil from the oil storage box through the oil extraction pipe, deliver it to the main pipe through the oil delivery pipe, and then deliver the lubricating oil evenly to the key friction points in the slide through the oil outlet holes of the four sets of branch pipes, replacing manual oil spraying. This can effectively avoid wear of the roller or slide caused by uneven lubrication, ensure the smoothness of the rolling displacement structure, and form an efficient synergy with the displacement adaptation structure.

[0013] 2. With the set collection components, when excess lubricating oil or waste oil mixed with a small amount of impurities accumulates in the slide, the solenoid valve can be opened as needed to direct the oil into the oil collection box below, preventing oil from dripping randomly onto the machine frame surface or the ground. This reduces unnecessary loss of lubricating oil and lowers the frequency of lubricating consumables replenishment. The filter screen installed inside the oil collection box can quickly intercept impurities when the oil enters the oil collection box. The lubricating oil filtered by the filter screen can be reused, thereby further improving the resource utilization rate of lubricating oil. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see the appendix Figure 1 and appendix Figure 3 - Appendix Figure 7 An adjustable base for a tube bundle dryer includes a dryer body 1 and a frame 5. A steam inlet end 2 is provided on the front side of the dryer body 1. A tube bundle body 3 is arranged inside the dryer body 1. Bearing seats 4 are provided on both the front and rear sides of the bottom of the dryer body 1. The rear bearing seat 4 is fixedly installed on the top of the frame 5. An adjustable base assembly 6 is provided below the dryer body 1. The adjustable base assembly 6 includes a small electric lubrication pump 603 and a fixed seat 610. Another set of bearing seats 4 is connected to rollers 602 through a bearing sliding seat 601. The small electric lubrication pump 603 is connected to an oil storage box 605 through an oil extraction pipe 604. The small electric lubrication pump 603 is connected to a main pipe 607 and a branch pipe 608 through an oil delivery pipe 606. Multiple sets of oil outlet holes 609 are provided on the outer wall of the branch pipe 608 in an equidistant manner.

[0025] Steam inlet 2 is located on the front side of the dryer body 1 and is used to access external steam. Steam enters the tube bundle body 3 through this end to provide a heat source for material drying. It is also the corresponding position of the "expansion end" when the tube bundle expands and contracts. The rear bearing seat 4 is directly fixed to the top of the frame 5 and is the "fixed end". The front bearing seat 4 is connected to the bearing sliding seat 601 and is the "expansion end".

[0026] The bearing sliding seat 601 is fixedly connected to the bottom of another set of bearing seats 4, which is located directly below the steam inlet end 2. The roller 602 is located at the bottom of the bearing sliding seat 601. The fixed seat 610 is fixedly installed on the top of the frame 5. The top of the fixed seat 610 is provided with a slide rail 611. The roller 602 is rotatably connected to the inside of the slide rail 611. The small electric lubrication pump 603 is fixedly installed on the top of the frame 5. One end of the oil suction pipe 604 is fixedly connected to the input end of the small electric lubrication pump 603, and the other end of the oil suction pipe 604 is fixedly connected to the inside of the oil storage box 605. The oil storage box 605 is fixedly installed on the top of the frame 5 and located on the left side of the fixed seat 610.

[0027] The bottom of the bearing sliding seat 601 is provided with two sets of rollers 602, and the top of the fixed seat 610 is provided with two slides 611. The two sets of rollers 602 roll inside the two sets of slides 611 respectively. The corresponding design of the two sets of rollers 602 and the two sets of slides 611 can further limit the displacement direction, avoid deviation, effectively offset the temperature stress of the tube, prevent the tube from deforming or the bearing seat 4 from being damaged, and ensure the long-term stable operation of the tube bundle body 3. Four sets of branch pipes 608 are provided, and the four sets of branch pipes 608 are respectively arranged in pairs on both sides of the two sets of slides 611.

[0028] One end of the oil supply pipe 606 is fixedly connected to the output end of the small electric lubrication pump 603, and the other end of the oil supply pipe 606 is fixedly connected to the inside of the main pipe 607. One end of the branch pipe 608 is fixedly connected to the inside of the main pipe 607. Both the main pipe 607 and the branch pipe 608 are located inside the fixed base 610.

[0029] Multiple sets of oil outlet holes 609 are equidistantly arranged on the outer wall of the branch pipe 608, serving as the "final outlet" for lubricating oil. The lubricating oil is evenly sprayed into the slide rail 611 through the oil outlet holes 609, ensuring that all positions in the slide rail 611 are covered with an oil film, thus guaranteeing the lubrication effect between the roller 602 and the slide rail 611.

[0030] Specifically, through the adjustable base assembly 6, the bearing seat 4 below the steam inlet 2 is connected to the roller 602 via the bearing sliding seat 601. The roller 602 rolls along the slide 611 of the fixed seat 610, converting the axial displacement caused by the thermal expansion and contraction of the tubes into low-resistance rolling motion. At the same time, for the rolling friction parts between the roller 602 and the slide 611, the small electric lubrication pump 603 draws lubricating oil from the oil storage box 605 through the oil extraction pipe 604, delivers it to the main pipe 607 through the oil delivery pipe 606, and then delivers the lubricating oil to the key friction points in the slide 611 through the oil outlet holes 609 of the four sets of branch pipes 608, replacing manual oil spraying, avoiding wear of the roller 602 or slide 611 caused by uneven lubrication, ensuring the smoothness of the rolling displacement structure, and forming a synergy with the displacement adaptation structure.

[0031] Please see the appendix Figure 1 Appendix Figure 3 and appendix Figure 8 The fixed base 610 is provided with a collection component 7 on its exterior. The collection component 7 includes a solenoid valve tube 701, which is fixedly connected to the front surface of the fixed base 610. A support plate 702 is provided directly below the solenoid valve tube 701 and is fixedly connected to the surface of the frame 5. A positioning groove 703 is provided on the top of the support plate 702. An oil receiving box 704 is provided inside the positioning groove 703. The oil receiving box 704 is located directly below the solenoid valve tube 701 and a filter screen 705 is provided inside the oil receiving box 704.

[0032] The solenoid valve tube 701 is fixedly connected to the front surface of the fixed base 610 and serves as a "controllable discharge channel for excess lubricating oil". When the lubricating oil accumulated in the slide rail 611, or waste oil mixed with a small amount of impurities, reaches a certain amount, the solenoid valve tube 701 can open the valve through a preset program to discharge the excess oil into the oil collection box 704 below, thus preventing the oil from accumulating in the slide rail 611 and forming sludge, which would affect the rolling of the roller 602.

[0033] Specifically, through the collection component 7, when excess lubricating oil or waste oil mixed with a small amount of impurities accumulates in the slide rail 611, the solenoid valve tube 701 can be opened as needed to direct the oil into the oil receiving box 704 below, preventing oil from dripping onto the surface of the frame 5 or the ground. This reduces lubricating oil consumption and lowers the frequency of lubricating material replenishment. The filter screen 705 installed inside the oil receiving box 704 can intercept impurities when the oil enters the oil receiving box 704. The lubricating oil filtered by the filter screen 705 can be reused, further improving the resource utilization rate of lubricating oil.

[0034] Working principle of this utility model: This utility model is an adjusting base for the tubes of a tube bundle dryer. First, after the operator starts the dryer body 1, external steam enters through the steam inlet 2 on the front side of the dryer body 1 and flows through the inside of the tubes of the tube bundle body 3, providing a heat source for material drying. As the temperature of the tubes rises, thermal expansion and contraction occur, and the front bearing seat 4 below the steam inlet 2 moves synchronously with the axial displacement of the tubes. At this time, the bearing sliding seat 601, which is fixedly connected to the bottom of the front bearing seat 4, drives the two sets of rollers 602 at its bottom to roll along the two slides 611 on the top of the fixed seat 610, converting the axial displacement of the tubes into low-resistance rolling motion. The corresponding design of the two sets of slides 611 and the two sets of rollers 602 can limit the displacement direction, avoid deviation, offset the temperature stress of the tubes, and ensure the stable operation of the tube bundle body 3.

[0035] While the roller 602 rolls along the slide rail 611, the operator presets the operating parameters of the small electric lubrication pump 603. The small electric lubrication pump 603 starts according to the preset program, draws lubricating oil from the oil storage box 605 through the oil extraction pipe 604, and delivers it to the main pipe 607 inside the fixed seat 610 through the oil delivery pipe 606. The main pipe 607 divides the lubricating oil into four sets of branch pipes 608. The lubricating oil is finally sprayed evenly into the key friction points in the slide rail 611 through multiple sets of oil outlet holes 609 on the outer wall of the branch pipes 608 to form an oil film, which prevents the roller 602 and the slide rail 611 from wearing due to insufficient lubrication and ensures smooth rolling displacement structure.

[0036] When excess lubricating oil or waste oil mixed with a small amount of impurities accumulates in the slide rail 611, the operator can trigger the solenoid valve 701 through the equipment control system, or rely on the preset program of the solenoid valve 701 to open the valve; the oil is directed through the solenoid valve 701 into the oil receiving box 704 below, preventing the oil from dripping onto the frame 5 or the ground; after the oil enters the oil receiving box 704, the internal filter 705 will intercept the impurities in the oil. The operator can periodically remove the oil receiving box 704 and replenish the filtered pure lubricating oil to the oil storage box 605 for recycling, reducing lubricating oil consumption and improving resource utilization.

[0037] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
