Description

Technical Field

[0001] The utility model belongs to the field of polyester chemical production and relates to an energy-saving high-pressure washing machine for a melt filter element. Background Art

[0002] Polyester is also called polyester or polyester resin. It is currently mainly produced by the reaction of terephthalic acid and ethylene glycol. In polyester chemical melt direct spinning enterprises, terephthalic acid and ethylene glycol undergo esterification and polymerization to form PET, which is then pressurized by a melt pump and filtered by a melt filter element before being transported to spinning, oiling, winding, external inspection, packaging, sizing, and boxing, ultimately forming the common polyester fiber and polyester fabric we know.

[0003] At present, high-pressure water washing plays a vital role in the cleaning of the melt filter element. However, at present, high-pressure washing machines almost all adopt the design of three high-pressure pump heads driving nine high-pressure nozzles. In normal use, the failure rate is high, and the pump head outlet pressure is excessive. Most of the work is wasted through the pressure-regulated return water, which consumes a lot of electricity. The failure rate of the high-pressure washing machine directly affects the quality of melt filter element cleaning. In the actual production of our company, the fundamental issue is to consider economic benefits. Because the water outlet pressure of the high-pressure pump head can meet the requirements of melt filter element cleaning, how to reduce the power consumption and failure rate of the high-pressure washing machine has become a technical problem in the industry.

[0004] Based on the above-mentioned prior art, in order to solve the deficiencies in the prior art, the utility model relates to an energy-saving design technology for a melt filter element cleaning machine, and specifically to a design of adding an intermediate tank at the outlet of a high-pressure pump to achieve energy-saving effects. Summary of the invention

[0005] The utility model solves the problems existing in the prior art and provides an energy-saving high-pressure washing machine for a melt filter element. The high-pressure washing machine can not only effectively reduce energy efficiency but also reduce the failure rate.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] An energy-saving high-pressure washing machine for a melt filter element, comprising:

[0008] Energy-saving high-pressure cleaning machine for melt filter elements, including:

[0009] A water inlet main pipe, which is used to transport water from the water source to the entire system;

[0010] A filter connected to the water inlet main pipe;

[0011] A high-pressure pump, which is connected to the filter through a water inlet pipe, and is connected to the intermediate tank through a water outlet pipe. A pressure regulating valve is also provided on the high-pressure pump;

[0012] Wherein, at least three high-pressure pumps are provided;

[0013] The intermediate tank is connected to the nozzle through a high-pressure water outlet pipe, and the nozzle is used to clean the filter element to be cleaned.

[0014] As a further improvement of the present solution, three high-pressure pumps are provided, and pressure regulating devices are provided on the high-pressure pumps.

[0015] As a further improvement of this solution, the pressure regulating device includes a reflux pipe and a pressure regulating valve.

[0016] As a further improvement of this solution, the high-pressure water outlet pipe is a hose.

[0017] As a further improvement of the present solution, the nozzles are arranged in a group of at least three, and a filter element to be cleaned is arranged at a corresponding position of each nozzle.

[0018] As a further improvement of the present solution, a pipeline is provided between the filter and the intermediate tank, and a filling valve is provided on the pipeline.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1) Through the setting of the intermediate tank, the original three high-pressure washing machine pump heads with high-pressure outlets connected to nine external high-pressure pipes and nozzles are transformed into two high-pressure washing machine pump heads driving nine external high-pressure pipes and nozzles. By closing the reflux pressure regulating valve to reduce the useless work of the pump head, it can be achieved that as long as any two pumps are turned on, the nine external high-pressure pipes and nozzles can be driven, thereby saving the electricity of one motor (12.7KW). According to the current polyester production capacity of 74.42 million tons, each 300,000-ton device is equipped with a high-pressure washing machine, totaling 248 units. If this transformation is implemented in the high-pressure cleaning machine industry, it can save more than 4 million yuan in total electricity costs for the polyester industry each year;

[0021] 2) By turning on any two pumps, nine external flushing high-pressure pipes and nozzles can be driven, and the original design of three motors and high-pressure flushing pump heads being turned on at the same time can be changed to any two being turned on in turn, reducing the equipment failure rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 2 It is a structural schematic diagram of a high-pressure cleaning machine in the prior art. DETAILED DESCRIPTION

[0024] The technical solution of the utility model is further described below in conjunction with the embodiments and drawings.

[0025] As shown in the figure, the energy-saving high-pressure washing machine for melt filter element includes:

[0026] A water inlet main pipe 1, which is used to transport water from a water source to the entire system;

[0027] A filter 2, the filter 2 is connected to the water inlet main pipe 1;

[0028] A high-pressure pump 3, which is connected to the filter through a water inlet pipe 31, and is connected to the intermediate tank 10 through a water outlet pipe 32. A pressure regulating valve 4 is also provided on the high-pressure pump 3;

[0029] Among them, at least three high-pressure pumps 3 are provided;

[0030] The intermediate tank 10 is connected to the nozzle 7 through the high-pressure water outlet pipe 6, and the nozzle 7 is used to clean the filter element 8 to be cleaned.

[0031] In the prior art, the flushing machine has the following problems: the failure rate during use is high, and the pump head outlet pressure is excessive, most of the work is wasted through the pressure regulating return water, the power consumption is large, and the failure rate of the high-pressure flushing machine directly affects the cleaning quality of the melt filter element.

[0032] In this embodiment, if Figure 1 As shown, in specific use, the energy-saving high-pressure cleaning machine for melt filter element can choose to start any two or one high-pressure pumps 3 according to actual needs, and will not affect the pressure of the nozzle connected to the high-pressure water outlet pipe, so as to meet the cleaning requirements of the filter element.

[0033] As a further preferred solution, three high-pressure pumps 3 are provided, and a pressure regulating device is provided on the high-pressure pump 3 .

[0034] As a further preferred solution, the pressure regulating device includes a return pipe 33 and a pressure regulating valve 4 .

[0035] like Figure 2 As shown, Figure 2 The high pressure cleaning machine of the prior art is used in the following specific tasks:

[0036] When the high-pressure cleaning machine is turned on, three high-pressure pumps 3 are turned on at the same time, and each pump corresponds to three nozzles. When one of the pumps is stopped, the nozzle pressure is only the water inlet pressure, which cannot meet the filter element flushing requirements.

[0037] like Figure 1As shown in the figure, it is an improved high-pressure cleaning machine. By setting an intermediate tank between the high-pressure pump 3 and the high-pressure water outlet pipe 6, it is only necessary to stop one high-pressure pump 3 and close the inlet and outlet valves of the pump. The other two high-pressure pumps 3 are running, and the high-pressure water flows into the intermediate tank. The pressure of the intermediate tank is adjusted by the reflux pipe and the valve, and then evenly distributed to the nine nozzles through the high-pressure water outlet pipe 6, which can also meet the filter element flushing requirements.

[0038] More specifically, by closing the reflux pressure regulating valve and reducing the useless work of the pump head, it can be achieved that by turning on any two pumps, nine external flushing high-pressure pipes and nozzles can be driven, thereby saving the electricity of one motor. According to the current polyester production capacity of 74.42 million tons, each 300,000-ton device is equipped with a high-pressure flushing machine, totaling 248 units. If this transformation is implemented in the high-pressure cleaning machine industry, it can save the polyester industry a total of more than 4 million yuan in electricity costs each year.

[0039] Furthermore, by turning on any two pumps, nine external flushing high-pressure pipes and nozzles can be driven, and the original design of three motors and high-pressure flushing pump heads being turned on at the same time can be changed to any two being turned on in turn, reducing the equipment failure rate.

[0040] As a further preferred embodiment, the high-pressure water outlet pipe 6 is a hose.

[0041] In this embodiment, a hose is used as the high-pressure water outlet pipe 6, and the hose is used to connect the intermediate tank and the nozzle 7, which provides flexible cleaning direction and distance, facilitates cleaning of filter elements at different positions, and is also convenient for adjustment according to actual needs.

[0042] As a further preferred embodiment, the nozzles 7 are arranged in groups of at least three, and a filter element 8 to be cleaned is arranged at a corresponding position of each nozzle 7 .

[0043] As a further preferred embodiment, a pipeline is provided between the filter 2 and the intermediate tank 10, and a filling valve 9 is provided on the pipeline. The above structure is provided to fill the intermediate tank 10 with desalted water and remove air when the equipment fails to be repaired.

[0044] During the specific operation, when the high-pressure cleaning machine is turned on, the high-pressure pump 3 is turned on to achieve efficient cleaning: the high-pressure water flow generated by the high-pressure pump 3 can more effectively clean the filter element 8 and remove impurities and blockages on the filter element.

[0045] Energy-saving considerations, such as reasonable layout and the use of efficient pumps, reduce energy consumption.

[0046] Multi-stage filtration: The setting of the water inlet main pipe 1 and the filter 2 provides multi-stage filtration to ensure the quality of water entering the system, thereby protecting key components such as the high-pressure pump 3 and the nozzle 7.

[0047] Adjustment function: The existence of the pressure regulating valve 4 allows the user to adjust the water pressure according to the cleaning needs to adapt to different cleaning tasks and improve the cleaning efficiency and flexibility.

[0048] Multi-pump configuration: At least three high-pressure pumps 3 are provided. Such a configuration can provide a greater flow rate and pressure, and at the same time provide a backup option in case of pump failure to ensure continuous operation of the system.

[0049] The preferred embodiments of the present invention are described herein, but the protection scope of the present invention is not limited thereto. Any modification or supplement or replacement of the specific embodiments described by technicians in the field of the present invention shall be included in the protection scope of the present invention.
