Technical Field

[0001] This utility model belongs to the technical field of electrostatic oil fume removal equipment. Background Technology

[0002] In the niche industry of kitchen fume purification, in addition to efficiently treating fumes, the ability of the equipment to perform automatic cleaning is equally important. Generally speaking, only large-scale electrostatic fume removal equipment is equipped with automatic cleaning functions, and even then, automatic cleaning usually requires a pressurized water pump, resulting in a complex structure and relatively high manufacturing costs.

[0003] In recent years, domestic patent databases have published several similar technical reports on electrostatic grease removal devices: [Application No.] ZL2014201965356, [Name] A High-Efficiency and Easy-to-Clean Electrostatic Grease Removal System, [Publication No.] CN203853169U, discloses a high-efficiency and easy-to-clean electrostatic grease removal system, including an air inlet pipe, an air outlet pipe, and an electrostatic grease removal module. The electrostatic grease removal module is connected to both the air inlet and outlet pipes. Each module includes multiple independently configured electrostatic grease removal units, which are vertically arranged, connected to the outlet pipe at the top and the air inlet pipe at the bottom. Each unit has an airflow regulating valve at its top or bottom to control the airflow volume. The airflow regulating valve adjusts the amount of exhaust gas entering each electrostatic grease removal unit. However, this device still suffers from problems such as inability to automatically clean, easy soiling, and short lifespan. Summary of the Invention

[0004] This utility model provides a vertical electrostatic grease removal device with automatic cleaning function, which has a good installation structure, simple production process, good cleaning effect, good use effect, and long service life. It solves the technical problems of current devices being easily contaminated, inconvenient to clean and maintain, and resulting in short service life.

[0005] This utility model provides a vertical electrostatic oil fume removal device with automatic cleaning function, including a main unit housing, a plate wire electric field installed in the main unit housing for filtering oil fumes, and a control box for controlling the operation of the plate wire electric field. A fan for exhaust ventilation is installed on the top of the main unit housing. A detachable air inlet reducer connected to an external air duct is installed on the side of the main unit housing. The control box is installed on the external side of the main unit housing via a rotating hinge. The opening and closing of the control box and the main unit housing is controlled by a door lock. The cleaning spray bar is installed inside the main unit housing. One cleaning spray bar is installed above each plate line electric field. A water replenishment float valve, a water inlet, and an automatic overflow outlet are fixedly installed on the side of the main unit housing below the detachable air inlet reducer. An automatic overflow outlet switch valve is installed through a pipe at the automatic overflow outlet. A cleaning water supply port is fixedly installed on the bottom side of the main unit housing. The cleaning water supply port is connected to the inlet of an automatic cleaning water pump through a pipe. The outlet of the automatic cleaning water pump is connected to the cleaning spray bar through a pipe. The bottom outlet switch valve is installed at the bottom of the main unit housing through a pipe. A detachable sealing plate is installed on the side of the main unit housing with bolts.

[0006] This invention employs a plate-wire electric field design, with the cleaning spray bar positioned above the electric field for more thorough cleaning. The nozzles on the spray bar spray clean water into the plate-wire electric field. Due to gravity and pump pressure, the clean water is sprayed onto the inner and outer walls of the electric field, thus cleaning it. Simultaneously, wastewater is recycled through a water storage tank below the main unit casing. Oil-water separation ensures relatively clean cleaning water each time, and the recycling of cleaning water conservates water resources. A detachable sealing plate design allows for left or right air intake depending on the situation. After a period of operation, the electric field remains relatively clean, enabling continuous and efficient operation. Furthermore, the equipment has a simple structure, is easy to operate, and has low maintenance costs. It solves the technical problems of current devices, such as susceptibility to contamination, inconvenient cleaning and maintenance, and short service life. It boasts advantages such as a reasonable installation structure, low manufacturing cost, relatively simple production process, strong self-cleaning ability, high self-cleaning effect, and long service life.

Detailed Implementation

[0014] The present invention will be further described below with reference to the specific accompanying drawings and embodiments.

[0015] like Figure 1-6 As shown, this utility model mainly includes a main unit housing 1, a plate wire electric field 12 installed inside the main unit housing 1 for filtering oil fumes, and a control box 7 for controlling the operation of the plate wire electric field 12. Its features include: a fan 6 for exhaust ventilation installed on the top of the main unit housing 1; a detachable air inlet reducer 3 connected to an external air duct installed on the side of the main unit housing 1; the control box 7 is installed on the external side of the main unit housing 1 via a rotating hinge; the opening and closing of the control box 7 and the main unit housing 1 is controlled by a door lock 2; cleaning spray bars 11 are installed inside the main unit housing 1; and a cleaning spray bar 5 is installed above each plate wire electric field 12. A water supply float valve 9, a water supply port 10, and an automatic overflow outlet 4 are fixedly installed on the side of the main unit housing 1 and below the detachable air inlet reducer 3. The automatic overflow outlet 4 is connected to an automatic overflow outlet switch valve 14 via a pipe. A cleaning water supply port 15 is fixedly installed on the bottom side of the main unit housing 1. The cleaning water supply port 15 is connected to the inlet of an automatic cleaning water pump 13 via a pipe. The outlet of the automatic cleaning water pump 13 is connected to a cleaning spray bar 11 via a pipe. The lower outlet switch valve 5 is installed at the bottom of the main unit housing 1 via a pipe. The detachable sealing plate 8 is installed on the side of the main unit housing 1 with bolts.

[0016] 1. During fume removal operation: The control box 7 generates high voltage through its internal transformer module, which is then supplied to the plate wire electric field 12. Oily fumes, driven by the suction of the fan 6, pass through the detachable air inlet reducer 3 and enter the main unit casing 1. When oily fume molecules pass over the plate wire electric field 12, they adhere to the inside of the field due to the electric field force. When the oily molecules accumulate to a certain volume, they naturally flow down the inner wall of the plate wire electric field 12 due to gravity, thus achieving the purpose of fume removal.

[0017] 2. Automatic cleaning operation: When the equipment does not need to run and needs to be cleaned, the control box 7 issues a cleaning command, and the transformer module inside the control box 7 stops working and stops outputting high voltage static electricity; at the same time, the automatic cleaning water pump 13 delivers the cleaning water at the bottom of the main unit housing 1 to the cleaning spray bar 11 through the cleaning water supply port 15. The spray holes on the cleaning spray bar 11 spray clean water onto the plate line electric field 12, and the electric field is cleaned. Simultaneously, under the influence of gravity, the wastewater flows to the bottom of the main unit casing 1, where oil and water separate, with the oil above the water. If the cleaning water needs to be replaced, open the lower outlet valve 5 located at the bottom of the main unit casing 1 to drain the oil and water through the pipe. Then close the lower outlet valve 5 and connect the water inlet 10 through an external water pipe to fill the bottom of the main unit casing 1 with water. If the water level at the bottom of the main unit casing 1 is too high, open the automatic overflow valve 14, and excess water will be discharged from the main unit casing 1 through the automatic overflow outlet 4. The water inlet float valve 9 can detect the water level inside the main unit casing 1. After a period of operation, the electric field cleaning process maintains a relatively clean state, enabling the equipment to operate continuously and efficiently.
