Description

Technical Field

[0001] The utility model relates to the technical field of external circulation treatment of ice machine lubricating oil, in particular to an external circulation treatment device for ice machine lubricating oil. Background Art

[0002] At present, when the ice machine is turned on in winter, it faces the situation of low ambient temperature and low oil temperature. The oil temperature of the ice machine should be above 35℃. If the temperature is too low, the Freon in the lubricating oil may not be vaporized, affecting the operation of the equipment. And as the operation cycle of the ice machine is extended, the lubricating oil quality in the ice machine will also decline, and the oil change frequency will increase.

[0003] In actual production, the lubricating oil is filtered through an external filter. However, when filtering is in progress, an oil film is easily formed on the filter plate, and impurities accumulate at the filter holes, which has a great impact on subsequent filtration and significantly reduces the filtration efficiency. In addition, after the filtration is completed, the filter residue is sticky and difficult to clean, and the filter needs to be opened for processing. During this process, there is a possibility that Freon will evaporate into the atmosphere. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide an ice machine lubricating oil external circulation treatment device, which heats the low-temperature lubricating oil through the arrangement of a heating tank and a delivery pump, thereby greatly improving the working efficiency of the ice machine in a low-temperature environment; through the coordinated use of a filter plate and a lower scraper, the oil film and impurities formed on the surface of the filter plate are scraped off during the filtration process, thereby greatly improving the filtration efficiency; through the coordinated use of a nitrogen pipeline and a flushing liquid inlet, the flushing liquid is added first, and then the nitrogen is introduced, and there is no need to disassemble, so that the filter plate can be cleaned of impurities, thereby avoiding the volatilization of Freon.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] The ice machine lubricating oil external circulation treatment device comprises an ice machine, which is connected to a reverse filter through a heating tank, and the reverse filter is connected to the ice machine through a return pipe. A filter plate is arranged inside the reverse filter, and a lower scraper driven by a driving motor is arranged below the filter plate.

[0007] The lubricating oil is first heated in a heating tank to improve its fluidity, and then filtered in a "bottom-in, top-out" manner. After filtering, the lubricating oil returns to the ice machine.

[0008] A heating coil is arranged inside the heating tank, and the ice machine is connected to the heating coil through a pipeline.

[0009] A delivery pump is connected between the heating tank and the reverse filter, the heating coil is connected to the delivery pump, and a reverse filter inlet pipe is connected between the delivery pump and the reverse filter. The flow rate of the lubricating oil entering the reverse filter through the delivery pump is slow, and the reverse filter plays a certain role in precipitation and stratification.

[0010] The reverse filter is provided with a nitrogen pipeline and a flushing liquid inlet, both of which are located above the filter plate. When flushing, the flushing liquid is first introduced above the filter plate, and then nitrogen is introduced, and the drive motor is turned on, and the lower scraper rotates accordingly to remove impurities on the filter plate.

[0011] The outer side of the reverse filter vertical wall is provided with an impurity discharge port, which is connected to the impurity storage tank through a pipeline, and the bottom of the reverse filter is provided with an inclined guide plate. The inclined guide plate is used for impurities to slide down into the impurity storage tank by gravity, and the lower side of the inclined guide plate is connected to the impurity discharge port.

[0012] The filter plate is provided with filter holes, and the upper edge of the lower scraper is tangent to the filter plate.

[0013] The working principle of the utility model is:

[0014] After the lubricating oil in the ice machine enters the heating tank, the heating tank and the delivery pump start working. The heated lubricating oil enters the reverse filter through the delivery pump and is filtered in a "bottom-in, top-out" manner; the driving motor drives the lower scraper to start rotating. After the filtration is completed, the lubricating oil enters the ice machine through the return pipe. The filtered impurities fall onto the inclined guide plate, and the flushing liquid is added through the flushing liquid inlet. Then nitrogen is introduced, and the driving motor is turned on. The lower scraper rotates to remove the impurities on the filter plate. The impurities enter the impurity storage tank through the impurity discharge port. Among them, the inclined guide plate is used for impurities to slide down to the impurity storage tank by gravity, and the lower side of the inclined guide plate is connected to the impurity discharge port.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model adopts the ice machine lubricating oil external circulation treatment device, and the low-temperature lubricating oil is heated by the setting of the heating tank and the delivery pump, which greatly improves the working efficiency of the ice machine in a low-temperature environment; through the coordinated use of the filter plate and the lower scraper, the oil film and impurities formed on the surface of the filter plate are scraped off during the filtration process, which greatly improves the filtration efficiency; through the coordinated use of the nitrogen pipeline and the flushing liquid inlet, the flushing liquid is added first, and then the nitrogen is introduced, and the filter plate can be cleaned without disassembly, thereby avoiding the volatilization of Freon.
