[0063] Please refer to Figures 1 to 24 The present invention provides a ceramic vacuum tube cleaning machine integrating cleaning and drying, comprising a pre-cleaning box 1, a fine cleaning box 2, a drying box 3, a product circulation line 5, a plurality of product brackets 6 and a PLC controller;

[0064] like Figure 1 , Figure 7 and Fig. 9 The pre-cleaning box 1 uses cold water as a cleaning medium to pre-clean the ceramic vacuum tube. One end of the pre-cleaning box 1 is the product input end of the ceramic vacuum tube cleaning machine that integrates cleaning and drying in the present invention, and the other end is connected to the fine cleaning box 2 through a corner 10. Two pre-cleaning stations 11 are arranged in the pre-cleaning box 1. The two pre-cleaning stations 11 can be interconnected or separated by a partition. A single pre-cleaning station 11 is respectively provided with a cleaning component 7 for flushing the end face and outer edge of the ceramic vacuum tube. The cleaning component 7 arranged on the pre-cleaning station 11 is connected to an external water tank through a pump and corresponding pipelines. The bottom of the pre-cleaning box 1 is used to receive the falling water after the pre-cleaning station 11 cleans the ceramic vacuum tube, and is externally connected to a water purification system. The clean water filtered and purified by the purification system is finally connected to the water inlet of the external water tank to form an external circulation, so as to realize the reuse of the cleaning medium-cold water;

[0065] like Fig.10 , Fig.11 and Fig.13 The cleaning assembly 7 preferably adopts a vertically arranged "L"-shaped main pipe 71 and a plurality of nozzles 72, wherein the arrangement of the nozzles 72 is as follows:

[0066] 4 to 6 nozzles 72 are arranged in a row on the vertical section of the "L"-shaped main pipe 71 to wash the outer edge of the ceramic vacuum tube;

[0067] Two nozzles 72 are arranged on the horizontal section of the "L"-shaped main pipe 71 and are oriented vertically downward to wash the end surface of the ceramic vacuum tube. The spacing between the two nozzles 72 on the horizontal section should correspond to the diameter of the ceramic vacuum tube. In order to meet the cleaning requirements of ceramic vacuum tubes of different diameters, the horizontal section of the "L"-shaped main pipe 71 can be set as a detachable structure for easy disassembly and replacement.

[0068] like Figures 15 to 17 The fine cleaning box 2 includes an alkali cleaning station 21, a first water cleaning station 22, an acid cleaning station 23, a second water cleaning station 24, a pure water cleaning station 25 and a hot air blowing station 26 which are arranged in sequence and separated from each other. Each station is provided with a cleaning component 7 which is arranged on the above-mentioned pre-cleaning station 11 and is used to wash the end face and outer edge of the ceramic vacuum tube. Each station is separated from each other by a partition to form a corresponding independent compartment. The bottom of each compartment is used to receive the cleaning medium after cleaning the ceramic vacuum tube at each station, wherein:

[0069] The cleaning component 7 disposed on the alkaline cleaning station 21 is fed with an alkaline cleaning medium, and is connected to the bottom of the compartment of the alkaline cleaning station 21 through a circulation pump to form an internal circulation, so as to realize the reuse of the alkaline cleaning medium;

[0070] The cleaning component 7 arranged on the first water cleaning station 22 is fed with the same cold water as the pre-cleaning station 11, which is used to clean the alkaline cleaning medium remaining on the ceramic vacuum tube. Like the pre-cleaning station 11, it is connected to the external water tank through a pump and corresponding pipelines, and the bottom of the compartment of the first water cleaning station 22 is connected to the bottom of the pre-cleaning tank 1 through a pump and corresponding pipelines. The falling water in the bottom compartment of the first water cleaning station 22 is pumped into the pre-cleaning tank 1 through a pump and corresponding pipelines, and then circulated to the external water tank after being processed by the above-mentioned purification system;

[0071] The cleaning component 7 disposed on the acid cleaning station 23 is fed with an acid cleaning medium, and is connected to the bottom of the compartment of the acid cleaning station 23 through a circulation pump and corresponding pipelines to form an internal circulation, so as to realize the reuse of the acid cleaning medium;

[0072] The cleaning component 7 arranged on the second water cleaning station 24 is fed with cold water, which is used to clean the acidic cleaning medium remaining on the ceramic vacuum tube. The cleaning component 7 on the station is externally connected to the above-mentioned external water tank through a pump and corresponding pipelines, and the bottom of the compartment of the second water cleaning station 24 is connected to the bottom of the pre-cleaning tank 1 through a pump and corresponding pipelines. The falling water in the bottom compartment of the second water cleaning station 24 is pumped into the pre-cleaning tank 1 through a pipeline, and then circulated to the external water tank after being processed by the purification system;

[0073] The cleaning component 7 arranged on the pure water cleaning station 25 is fed with pure water (deionized water) for the final cleaning of the cleaning ceramic vacuum tube. The cleaning component 7 on the station is connected to a pure water tank through a pump and corresponding pipelines. It should be noted that a constant temperature heating device is arranged inside the pure water tank to ensure that the cleaning pure water fed into the pure water cleaning station 25 is warm water, thereby improving the cleaning quality. The bottom of the compartment of the pure water cleaning station 25 is also connected to the bottom of the pre-cleaning tank 1 through a pump and corresponding pipelines. The falling water in the bottom compartment of the second water cleaning station 24 is pumped into the pre-cleaning tank 1 through a pipeline, and then circulated to the external water tank after being processed by the water purification system, and serves as the cleaning medium for the pre-cleaning station 11, the first water cleaning station 22 and the second water cleaning station 24;

[0074] The cleaning component 7 on the hot air blowing station 26 is not fed with a cleaning medium, but with hot air for blowing. The structure of the cleaning component 7 on this station may not be changed. It is used to blow the cleaned ceramic vacuum tube to prepare for the drying process. Specifically, a hot air blower 261 should be equipped and connected to the inlet of the cleaning component 7 through an air duct.

[0075] It should be noted that the cleaning medium circulated in the above-mentioned alkaline cleaning station 21 and the acid cleaning station 23 will deteriorate after long-term use and cannot meet the cleaning needs, so it is necessary to replace new cleaning media from time to time. For the convenience of operation, the compartments of the alkaline cleaning station 21 and the acid cleaning station 23 are respectively provided with a adding port with a door at the top and a drain port at the bottom, and the deteriorated cleaning medium is discharged from the drain port at the bottom of each station compartment, and then new cleaning medium is added to the compartments of the above-mentioned two stations through the adding port at the top. In addition, it is necessary to observe and inspect each station through the adding port. Although it is not necessary to manually replace new cleaning media at other stations, daily inspection and observation of the operating status are necessary. Therefore, the tops of the compartments of the pre-cleaning station 11, the first water cleaning station 22, the second water cleaning station 24, the pure water cleaning station 25 and the hot air blowing station 26 are also provided with inspection ports with doors like the adding port;

[0076] In order to save costs, Fig.15 , a pump and corresponding pipeline arrangement can be used to connect the bottom of each station compartment of the first water cleaning station 22, the second water cleaning station 24 and the pure water cleaning station 25 with the bottom of the pre-cleaning tank 1 respectively. Specifically, the water outlet of the pump is connected to the bottom of the pre-cleaning tank 1 through a pipeline, and the water inlet is connected to a main pipeline. Branch pipes are opened on the main pipeline, which are connected to the bottom of each station compartment of the first water cleaning station 22, the second water cleaning station 24 and the pure water cleaning station 25 respectively. The falling water at the bottom of the compartments of the first water cleaning station 22, the second water cleaning station 24 and the pure water cleaning station 25 is collected in the main pipeline through the above-mentioned branch pipes and then pumped into the pre-cleaning tank 1 through the pump;

[0077] like Fig.18 and Fig.19 The drying box 3 is an "L"-shaped structure connected by a corner 10, and a self-opening door 31 is provided at both ends. One end is connected to the output end of the fine cleaning box 2 through the corner 10, and the other end is used as the product output end of the ceramic vacuum tube cleaning machine integrating cleaning and drying of the present invention, which is used to dry the ceramic vacuum tube output after being cleaned by the fine cleaning box. A plurality of electric heating wires 32 are provided inside the drying box 3. In order to reduce the loss of heat energy, the box body of the drying box 3 is provided with an interlayer, and a heat preservation cotton is provided in the interlayer;

[0078] A blower is also provided in the corner 10 of the drying box 3 to realize heat circulation in the drying box 3 and increase the uniformity of drying. Therefore, a corresponding exhaust pipe should be provided on one side of the drying box 3;

[0079] like Figure 1 , Figure 7 and Figure 8 One end of the transition box 4 is connected to the product output end of the drying box 3, and the other end is connected to the product input end of the pre-cleaning box 1 through the corner 10. The transition box 4 not only plays the role of transition connection, but also actually serves as a material feeding and receiving station, so that a single person can perform the material feeding operation of the ceramic vacuum tube products to be cleaned and the material receiving operation of the ceramic vacuum tubes after cleaning and drying at one station;

[0080] like Figure 20 to Figure 24 The product circulation line 5 sequentially passes through the pre-cleaning box 1, the fine cleaning box 2, the drying box 3 and the transition box 4 to form a cleaning and drying integrated production line with product input-cold water pre-cleaning-alkali cleaning-acid cleaning-pure water cleaning-hot air blowing-drying-product output. The product circulation line 5 includes a servo motor 51, a main driving wheel 52, a plurality of tensioning wheels 53 and a transmission chain 54. The main driving wheel 52 and the plurality of tensioning wheels 53 are connected by the transmission chain 54 to form a closed-loop circulation line. A plurality of insertion rods 55 corresponding to the product bracket 6 are evenly arranged on the transmission chain 54. The product bracket 6 is respectively mounted on an insertion rod 55, and the ceramic vacuum tube is mounted on the product bracket 6. The product bracket 6 can support and limit the ceramic vacuum tube.

[0081] For the purpose of circulation, the ceramic vacuum tube cleaning machine integrating cleaning and drying of the present invention is designed as a rectangular structure with four corners 10. It should be noted that the corner 10 included in the "L"-shaped drying box 3 is a closed structure as a whole, but has an avoidance hole corresponding to the transmission chain 54. The other corners 10 are not limited, wherein:

[0082] like Figure 20 to Figure 22The servo motor 51 is located in the corner 10 connecting the fine cleaning box 2 and the drying box 3. The main driving wheel 52 is installed at the output end of the servo motor 51. A tensioning wheel 53 is respectively provided in the other three corners 10. The tensioning wheel 53 is respectively installed in the corner 10 through the rotating shaft and the outer spherical bearing seat with a seat. A bracket for fixing the outer spherical bearing seat with a seat should be provided inside the corner 10. In order to facilitate the maintenance of the product circulation line 5 and the adjustment of the tension of the transmission chain 54, an inspection door is respectively provided on the side of each corner 10;

[0083] The pre-cleaning box 1, the fine cleaning box 2 and the drying box 3 are respectively provided with chain grooves 20 corresponding to the transmission chain 54. The transmission chain 54 is located in the chain grooves 20. In order to reduce the resistance and wear caused by the hard contact between the transmission chain 54 and the chain grooves 20, a plurality of rollers 541 are evenly provided at the bottom of the transmission chain 54.

[0084] During the operation of the product circulation line 5, the cleaning medium sprayed on the transmission chain 54 will cause the transmission chain 54 to rust and be corroded by the alkaline and acid cleaning medium, which will affect the normal operation of the entire product circulation line 5. Therefore, a plurality of cover plates 56 connected in series by plug rods 55 are provided above the transmission chain 54 to prevent the cleaning medium from being sprayed on the transmission chain 54, which can play a better protective role. The width of the cover plate 56 should be greater than the width of the chain groove 20 to prevent the cleaning medium from falling into the chain groove 20 and contacting the transmission chain 54;

[0085] In order to achieve the purpose of self-rotation of the ceramic vacuum tube during cleaning, the two pre-cleaning stations 11, the alkali cleaning station 21, the first water cleaning station 22, the acid cleaning station 23, the second water cleaning station 24, the pure water cleaning station 25 and the hot air blowing station 26 are respectively provided with a driving assembly 9 that cooperates with the product bracket 6, and the driving assembly 9 provides power to drive the product bracket 6 to rotate, thereby driving the ceramic vacuum tube mounted on the product bracket 6 to rotate;

[0086] As a preferred solution, Figures 3 to 5 The product bracket 6 includes a bracket body 61, an anti-deflection pad 63 and a pressure head 64. The bracket body 61 is used to support and limit the ceramic vacuum tube, and includes a hollow shaft 611, a disc 612 and a plurality of load-bearing ribs 613. A bearing 62 is respectively provided at both ends of the hollow shaft 611, and the bearings 62 are coaxially fixed to the ends of the hollow shaft 611;

[0087] The disc 612 is coaxially mounted on one end of the hollow shaft 611;

[0088] The number of the load-bearing ribs 613 is 3 to 6, one end of each load-bearing rib 613 is fixed on the hollow shaft 611, and the other end is fixed on the disc 612, and an angle of 15 to 45° is formed between the load-bearing rib 613 and the hollow shaft 611, preferably 30°;

[0089] The product bracket 6 is sleeved on the insertion rod 55, and the ceramic vacuum tube is sleeved on the product bracket 6, and the matching anti-deflection pad 63 and pressure head 64 are respectively located above the product bracket 6 and sleeved on the above-mentioned insertion rod 55, the bottom of the ceramic vacuum tube is supported by a plurality of load-bearing ribs 613, and the pressure head 64 presses the anti-deflection pad 63, and the anti-deflection pad 63 is provided with a plurality of protrusions around it, and the diameter of the circle where the farthest ends of these protrusions are located should correspond to the inner diameter of the ceramic vacuum tube, and actually be slightly smaller than the inner diameter of the ceramic vacuum tube, and the height of the anti-deflection pad 63 should be lower than the end of the ceramic vacuum tube, so as to prevent the ceramic vacuum tube from deviating during the cleaning process, resulting in incomplete cleaning;

[0090] The arrangement of multiple load-bearing ribs 613 can achieve contact between the corners where the end face of the ceramic vacuum tube intersects with the inner wall and the load-bearing ribs 613, which can reduce the wear of the end face. In order to further reduce the wear of the end face of the ceramic vacuum tube, a protective sleeve 65 is also wrapped on the load-bearing rib 613. The protective sleeve 65 is provided with a notch along the length direction, and the protective sleeve 65 is sleeved on the load-bearing rib 613 through the notch.

[0091] like Fig.14 The driving assembly 9 includes a driving motor 91 and a turntable 92 mounted on the output end of the driving motor 91. The outer edge of the turntable 92 contacts the outer edge of the disc 612. The turntable 92 is driven to rotate by the driving motor 91, thereby driving the disc 612 to rotate, so as to achieve the purpose of the entire product bracket 6 driving the ceramic vacuum tube to rotate. In order to increase the friction between the turntable 92 and the disc 612, a plurality of anti-slip grooves can be evenly provided on the outer edges of the turntable 92 and the disc 612;

[0092] Furthermore, in order to ensure the transmission stability between the rotating disk 92 and the circular disk 612, the two can also be directly replaced by a matching transmission gear set;

[0093] In the specific implementation of the present invention, the driving assembly and the cleaning assembly on each station are arranged opposite to each other and are respectively located on both sides of the transmission chain 54. In order to prevent the cleaning medium from being sprayed on the driving motor 91 and affecting its normal operation, the driving assembly 9 needs to be waterproofed accordingly. Specifically, a protective cover 30 is provided on the inner side plate of the fine cleaning box 2 corresponding to each station, and the driving motor 91 is fixed in the protective cover 30. The output end of the driving motor 91 extends out of the bottom of the protective cover 30 and is assembled with the turntable 92. An inspection door is provided on one side of the protective cover 30 to facilitate the inspection of the driving assembly 9.

[0094] As another embodiment, Figure 6The bracket body 61 is composed of a hollow shaft 611, a plurality of load-bearing ribs 613, and a plurality of blades 614 arranged between the load-bearing ribs 613 and the hollow shaft 611. The number of blades 614 is 3 to 6. Preferably, the blade 614 is a right-angled triangle, one of which is parallel to the axial direction of the hollow shaft 611 and welded on the hollow shaft 611, and the other right-angled side is perpendicular to the axial direction of the hollow shaft 611. When the blade 614 is a right-angled triangle, the load-bearing rib 613 is arranged parallel to the hypotenuse direction of the blade 614, and a stop rod is arranged at the end of the right-angled side perpendicular to the axial direction of the blade 614 and the hollow shaft 611. A gap of not less than 5 mm is formed between the stop rod and the free end of the load-bearing rib 613. The protective cover 65 The protective cover 65 can be slowly inserted upward onto the load-bearing rib 613 through the notch. When replacement is required, the protective cover 65 can be pulled out from the notch. The advantage of adopting such a structure of the bracket body 61 is that during the cleaning process of the ceramic vacuum tube, the cleaning assembly 7 arranged at each station will continuously apply a fixed direction force to the blade 614 while flushing the ceramic vacuum tube, so that the product bracket 6 can rotate on the insertion rod 55, so that the ceramic vacuum tube rotates, thereby achieving the purpose of cleaning the ceramic vacuum tube while rotating without providing additional power. However, there are certain disadvantages, and the rotation rate of the ceramic vacuum tube cannot be accurately controlled, so there is a certain limitation on the regulation of the cleaning efficiency.

[0095] The PLC controller is electrically connected to the product circulation line, the pumps and circulation pump 8 involved in each workstation, the drive assembly 9 and the heating wire 32, respectively, and controls the start and stop of the heating wire 32, the servo motor 51, the drive motor 91 and the pumps and circulation pump 8 related to each workstation, so as to realize continuous automatic cleaning of the ceramic vacuum tube. In order to facilitate the wiring operation, a circle of wire pipe is provided on the inner circle of the entire ceramic vacuum tube cleaning machine integrating cleaning and drying, and a wiring box and wire pipe are also provided on the outside of each workstation.

[0096] Working principle: several product brackets 6 are respectively mounted on the respective insertion rods 55 of the product circulation line 5, and the electric heating wire 32 in the drying box 3 is started through the PLC controller for heating, and the pump and circulation pump 8 connected to the cleaning component 7 arranged on each station are started to make the cleaning medium of each station perform corresponding internal and external circulation, and the ceramic vacuum tube to be cleaned is mounted on the product bracket 6 located on the feeding and receiving station, and the servo motor 51 is started, and the product circulation line 5 runs, and the ceramic vacuum tube to be cleaned is mounted on the product bracket 6 passing through the feeding and receiving station in turn. When the first ceramic vacuum tube to be cleaned arrives at the first pre-cleaning station 11, the product circulation line 5 is paused, and the cleaning component 7 on the pre-cleaning station 11 uses cold water to perform the first pre-cleaning of the ceramic vacuum tube. After the cleaning is completed, the product circulation line 5 is started and the first ceramic vacuum tube is transferred to the second pre-cleaning station 11 and then paused. At the same time, the second ceramic vacuum tube to be cleaned will arrive at the first pre-cleaning station 11, and the two The pre-cleaning station 11 pre-cleans the ceramic vacuum tubes on the station at the same time, and then the product circulation line 5 drives the ceramic vacuum tubes to pass through the alkaline cleaning station 21, the first water cleaning station 22, the acid cleaning station 23, the second water cleaning station 24, the pure water cleaning station 25 and the hot air blowing station 26 in turn, and pauses for a period of time at each of the above stations to clean and blow the ceramic vacuum tubes at each station accordingly. The pause time is preferably 5 to 10 seconds. The ceramic vacuum tubes after blowing at the hot air blowing station 26 enter the drying box 3 from the output end of the fine cleaning box 2 under the action of the product circulation line 5. The ceramic vacuum tubes are dried within the travel time of the drying box 3 and output from the product output end of the drying box 3 to the transition box 4. The cleaned and dried ceramic vacuum tubes are removed from the product circulation line 5, and new ceramic vacuum tubes to be cleaned are put on and enter the product input-cold water pre-cleaning-alkali cleaning-acid cleaning-pure water cleaning-hot air blowing-drying-product output integrated cleaning and drying production line;

[0097] The heating wire 32, product circulation line 5, drive motor and the start and stop of the pump and circulation pump 8 related to each station involved in the present invention are all controlled by the control program set in the PLC controller. The above control program is a common prior art and will not be described in detail here.

[0098] During actual use of the present invention, when the ceramic vacuum tube on the product circulation line 5 stops at the hot air blowing station 26 at the very end of the fine cleaning box 2, the ceramic vacuum tube located in the front will stop in sequence at the pure water cleaning station 25, the second water cleaning station 24, the acid cleaning station 23, the first water cleaning station 22, the alkaline cleaning station 21, and the pre-cleaning station 11 for corresponding cleaning. The above-mentioned working position relationship can be met by limiting the spacing between adjacent stations and adjacent insertion rods 55 on the product circulation line 5.

[0099] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
