Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aluminum sheet and strip production technology, and in particular relates to a preheating device for aluminum sheet and strip production. Background Technology
[0002] Aluminum sheet and strip refer to aluminum sheets or strips made primarily from aluminum and mixed with other alloying elements. They are an important basic material for economic development and have a wide range of applications.
[0003] The prior art discloses a preheating device for aluminum sheet and strip production, with publication number CN219093145U, for a hot oil system of a cold rolling mill. The hot oil system includes a hot oil tank, which is connected to a rolling oil tank. The rolling oil tank is connected to a preheater, which is connected to a filter. The filter is connected to the hot oil tank. A solenoid valve I and an oil pump I are installed between the hot oil tank and the rolling oil tank. This utility model is specifically designed for heating the oil in a hot oil system. This solution adds a preheating mechanism between the rolling oil tank and the hot oil tank, preheating the oil supplied from the rolling oil tank before sending it to the heater inside the hot oil tank for further heating. This ensures stable oil temperature and avoids affecting the control of the strip shape. During aluminum strip production, friction between the rolls and the strip generates tiny metal shavings, which enter the rolling oil. Simultaneously, impurities and oil stains from the previous process's strip surface also enter the rolling oil through flushing. These impurities not only affect the strip quality but also contribute to the problem that, while the oil can be filtered, the cleaning effect on the filter screen is insufficient, failing to quickly remove impurities trapped by the filter. Utility Model Content
[0004] In view of the problems existing in the prior art, this utility model provides a preheating device for aluminum sheet and strip production that can overcome or at least partially solve the above problems.
[0005] This utility model is implemented as follows: a preheating device for aluminum sheet and strip production includes a preheating unit and a filtration assembly. The preheating unit includes a base plate, multiple supports, a top plate, a preheater, a solenoid valve, and an oil pump. The bottoms of the multiple supports are fixedly connected to the four corners of the top of the base plate, and the tops of the multiple supports are fixedly connected to the four corners of the bottom of the top plate. The bottom of the preheater is fixedly connected to the right side of the top of the top plate. The bottom of the preheater is fixedly connected to the top of the solenoid valve via a pipe, and the bottom of the solenoid valve is fixedly connected to the left side of the oil pump via a pipe.

The top of the oil inlet pipe passes through the filter box and is fixedly connected to the bottom of the oil pump. A scraping assembly is provided on the top of the two filter screens, and a transmission assembly is provided on the top of the two scraping assemblies.
[0006] The preheating device is used to preheat the oil.
[0007] The filter assembly is used to filter impurities in the oil.
[0008] To remove impurities from the tops of the two filter screens, the scraping assembly preferably includes two rotating columns, multiple scrapers, and two rotating gears. The multiple scrapers are fixedly connected to the two rotating columns near one side of each column, and their bottoms are respectively in contact with the tops of the two filter screens. The tops of the two rotating columns penetrate the filter box and extend to its top. The top surfaces of the two rotating columns are fixedly connected to the interiors of the two rotating gears. Through the scraping assembly, the rotation of the multiple scrapers on top of the two filter screens removes the impurities, thus eliminating the need for manual cleaning of the two filter screens.
[0009] To enable rapid cleaning of the two filters, the transmission assembly preferably includes a housing, a motor, a transmission gear, and a toothed belt. The bottom of the housing is fixedly connected to the top of the filter box, and the bottom of the motor is fixedly connected to the top of the housing.

Through the transmission assembly, the motor can drive the transmission gear and rotate the toothed belt. The toothed belt will drive the two rotating gears to rotate, thereby driving the two rotating gears to drive the two rotating columns and causing multiple scrapers to rotate.
[0010] To facilitate the collection of scraped impurities, preferably, collection boxes are inserted and connected to the bottom of both the front and rear sides of the filter box, and both are located at the bottom of the fixed plate. Through the two collection boxes, as the multiple scrapers rotate, when the impurities are at the top of the collection boxes, the impurities will fall into the inside of the collection boxes.
[0011] To prevent the two collection boxes from shaking, preferably, the top of both the front and rear sides of the filter box is fixedly connected with an inlet, and a pin is inserted into the inside of each of the two inlets.

Both pins are made of relatively heavy materials.
[0012] To prevent oil from falling into the collection box, preferably, both of the flow guides are fixedly connected to the inside of a baffle, and the bottom of both baffles can fit against the top of the multiple scrapers. Both baffles act as a blockage, allowing the oil to only pass through the two filters and fall downwards.
[0013] In order to discharge the impurities from the top of the two filter screens, preferably, each of the two filter screens has a discharge port inside, which is located at the top of the two collection boxes respectively. When the multiple scrapers rotate, the impurities are scraped down to the discharge port, and then fall from the discharge port into the collection box.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This invention, through the installation of a preheating device, a base plate, a support, and a top plate, preheats the oil, filters impurities from the oil using a filter assembly, removes impurities from the top of the two filter screens through the combined use of a scraping assembly and a transmission assembly, facilitates the collection of scraped impurities through a collection box and a discharge port, prevents the two collection boxes from shaking through a plug and a pin, and prevents oil from falling into the collection boxes through a stop block. This achieves the effect of quickly removing impurities from the top of the filter screens without manual cleaning and facilitating the collection of the removed impurities.

The two filter screens 203 are respectively installed on the front and rear sides of the interior of the fixed plate 202. The bottoms of the two flow guides 204 are fixedly connected to the top of the fixed plate 202 and are located on top of the two filter screens 203. The bottom of the oil inlet pipe 205 is fixedly connected to the top of the two flow guides 204, and the top of the oil inlet pipe 205 passes through the filter box 201 and is fixedly connected to the bottom of the oil pump 106. Scraping components 3 are provided on the top of the two filter screens 203. A transmission assembly 4 is provided at the top; a preheating device 1 is used to preheat the oil; a filter assembly 2 is used to filter impurities in the oil. In order to remove impurities from the top of the two filter screens 203, a scraping assembly 3 includes two rotating columns 301, multiple scrapers 302, and two rotating gears 303. The multiple scrapers 302 are located near one side of the two rotating columns 301 and are fixedly connected to the two rotating columns 301 respectively. The bottom of the multiple scrapers 302 is respectively attached to the top of the two filter screens 203. The top of the two rotating columns 301 penetrates the filter box 201 and extends to the top of the filter box 201. The top of the surface of the two rotating columns 301 is fixedly connected to the inside of the two rotating gears 303 respectively. Through the scraping assembly 3, the multiple scrapers 302 remove impurities from the top of the two filter screens 203. The rotation at the top of the 03 filter can scrape away impurities from the top of the two filter screens 203, thus eliminating the need for manual cleaning of the two filter screens 203. To facilitate quick cleaning of the two filter screens 203, the transmission assembly 4 includes a housing 401, a motor 402, a transmission gear 403, and a toothed belt 404.

To discharge impurities from the top of the two filter screens 203, each filter screen 203 has a discharge port 9 located at the top of the two collection boxes 5. As the multiple scrapers 302 rotate, when impurities are scraped down to the discharge port 9, they fall from the discharge port 9 into the collection box 5.
[0026] The working principle of this utility model:
[0027] When it is necessary to discharge the heated oil, the solenoid valve 105 and the oil pump 106 are opened, thereby drawing the oil out of the preheater 104. The oil then enters the interior of the two guide shrouds 204 through the oil inlet pipe 205. Blocked by the baffle 8, the oil passes through the two filter screens 203, which intercept impurities in the oil. After each use of a portion of the oil, the solenoid valve 105 and the oil pump 106 are closed. At this time, the motor 402 is activated, causing its output to drive the rotating gear 303 to rotate. The rotating gear 303 then causes the toothed belt 40... 4. Rotate, which will drive the two rotating gears 303 to rotate. The two rotating gears 303 will cause the two rotating columns 301 to rotate and cause the multiple scrapers 302 to rotate. The multiple scrapers 302 will rotate and scrape off the impurities on the top of the two filter screens 203. When the impurities are scraped to the discharge port 9 of the two filter screens 203, the impurities will fall into the inside of the two collection boxes 5. After scraping is completed, the multiple scrapers 302 are moved to their original positions, and the pins 7 are pulled to move them out of the inside of the collection box 5 and the port 6, so that the collection box 5 can be moved out of the inside of the filter box 201.
