Description

Technical Field

[0001] This utility model belongs to the field of engine cooling technology, and in particular relates to an anti-clogging oil engineering engine radiator. Background Technology

[0002] In the field of petroleum engineering, engines often operate in dusty and harsh environments, posing a severe challenge to the reliability of their radiators. Traditional air-cooled radiators draw in large amounts of dusty air during operation, and dust particles easily accumulate on the surface of the radiator fins, forming a heat insulation layer that leads to a sharp decrease in heat dissipation efficiency and raises the risk of engine overheating. At the same time, accumulated dust may clog the gaps between fan blades, increasing rotational resistance and even causing motor stalling and damage. Existing protective measures mostly involve installing ordinary filters at the air inlet, but the filters themselves need to be cleaned or replaced frequently, otherwise it will increase air intake resistance and has limited filtering effect on fine dust. How to achieve continuous self-cleaning of the radiator intake air without affecting ventilation efficiency and prevent dust adhesion and accumulation has become a key technical challenge to ensure the stable operation of petroleum equipment.

[0003] To address these issues, we provide a clog-resistant petroleum engineering engine radiator. Utility Model Content

[0004] The purpose of this invention is to provide a clog-resistant radiator for petroleum engineering engines. This is achieved by installing an air intake duct and an air-cooling sleeve at both ends of a fan. A charge application frame and an adsorption frame are fitted inside the air intake duct, and an adsorption conveyor belt is installed inside the adsorption frame. The air-cooling pipe is placed inside the air-cooling sleeve and connected to the water-cooling chamber of the diesel engine. The fan draws air from one end of the air intake duct into the charge application frame, causing dust particles in the air to become charged. The charged dust particles then enter the adsorption frame and come into contact with the adsorption conveyor belt, which, carrying the opposite charge, adsorbs and carries the dust out. This process removes dust from the air, preventing the fan rotor from jamming due to dust being sucked in, or preventing dust from adhering to the air-cooling pipe and reducing the cooling effect of the coolant in the air-cooling pipe.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an anti-clogging radiator for petroleum engineering engines, comprising a fan, an air-cooling sleeve, and a dust removal component. The dust removal component includes an air inlet duct, a charge application frame, and an adsorption assembly. One end of the air inlet duct is fitted onto the air inlet side of the fan, and the air-cooling sleeve is fitted onto the air outlet side of the fan. The charge application frame is fitted inside the air inlet duct at the end furthest from the fan. The adsorption assembly includes an adsorption frame and a set of adsorption conveyor belts. The adsorption frame is fitted inside the air inlet duct at the end closest to the fan. Two shaft supports are respectively provided at the upper and lower ends of the air inlet duct, with two shaft supports at each end. A set of belt shafts is rotatably arranged between them. The adsorption conveyor belt passes through the upper and lower side walls of the adsorption frame and the air inlet duct. The two ends of the adsorption conveyor belt are respectively sleeved on the outside of the belt shafts at the upper and lower ends. Each belt shaft is synchronously driven and connected through a sleeve belt. One of the belt shafts is driven and connected to the output end of the motor. The charge application frame is connected to voltage. A charge application roller is set on one side of the lower end of the adsorption conveyor belt. The charge application roller is connected to a voltage of opposite polarity to that of the charge application frame. Metal adsorption plates are arrayed and connected along the length of the outer belt surface of the adsorption conveyor belt.

[0006] A further feature of this invention is that a set of charge application plates are arranged vertically in an array within the charge application frame, perpendicular to the length direction of the air inlet duct. A set of inclined guide plates are arranged in an array on both sides of the charge application plates along the length direction of the air inlet duct. The plates of the inclined guide plates are inclined to one end of the adsorption frame, and the inclined guide plates on the surfaces of each pair of adjacent charge application plates are staggered.

[0007] A further feature of this invention is that a charge neutralization roller is provided on the side of the lower end of the adsorption conveyor belt away from the charge application roller, and the charge neutralization roller is connected to a voltage of opposite polarity to that connected to the charge application roller.

[0008] A further feature of this invention is that a diversion cone is provided at one end of the adsorption frame near the charge application frame. Each diversion cone is respectively disposed between the two sides of the adsorption conveyor belt. The pointed end of the diversion cone faces one side of the charge application frame, and the width of the diversion cone is equal to the distance between the two sides of the adsorption conveyor belt.

[0009] A further feature of this invention is that a coarse filter cover is fitted onto the end face of the air inlet duct away from the fan.

[0010] A further feature of this invention is that a set of air-cooled pipes are fitted inside the air-cooled pipe sleeve, the pipe axis of the air-cooled pipes is parallel to the pipe axis of the air-cooled pipe sleeve, and the end faces of each adjacent air-cooled pipe are connected by a bend, wherein one end of two air-cooled pipes is bent to one side and passes through the air-cooled pipe sleeve.

[0011] This utility model has the following beneficial effects: This invention utilizes the synergistic effect of a charge application frame and an adsorption component set inside the air intake duct to charge dust in the air using an electrostatic field. The dust is then efficiently captured and removed from the air duct by an adsorption conveyor belt carrying the opposite charge, achieving efficient dust removal from the air intake. This fundamentally prevents dust accumulation on the heat sink and fan, ensuring the continuous and efficient operation of the radiator.

[0012] This invention achieves continuous automatic removal of captured dust and electrode regeneration through the design of a circulating adsorption conveyor belt and charge neutralization roller. This eliminates the need for downtime maintenance during the dust removal process, effectively overcoming the drawbacks of traditional filters that require frequent cleaning. It significantly improves the adaptability and maintenance convenience of the radiator in dusty environments. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0021] Please see Figures 1 to 5This utility model relates to an anti-clogging radiator for petroleum engineering engines, comprising a fan 1, an air-cooling sleeve 2, and a dust removal component 3. The dust removal component 3 includes an air inlet duct 301, a charge application frame 302, and an adsorption assembly 303. One end of the air inlet duct 301 is fitted onto the air inlet side of the fan 1, the air-cooling sleeve 2 is fitted onto the air outlet side of the fan 1, the charge application frame 302 is fitted onto the end of the air inlet duct 301 furthest from the fan 1, and the adsorption assembly 303 includes an adsorption sleeve. The system consists of a frame 303a and a set of adsorption conveyor belts 303b. The adsorption frame 303a is fitted inside the air inlet duct 301 near the fan 1. Two shaft supports 301a are respectively installed at the upper and lower ends of the air inlet duct 301. A set of belt shafts 301b is rotatably mounted between the two shaft supports 301a at each end. The belt surface of the adsorption conveyor belts 303b passes through the adsorption frame 303a and the upper and lower sidewalls of the air inlet duct 301. Both ends of the adsorption conveyor belts 303b are respectively fitted onto the upper and lower sidewalls. On the outer sides of the belt shafts 301b at both ends, each belt shaft 301b is synchronously connected via a sleeve belt. One of the belt shafts 301b is connected to the output end of the motor. The charge application frame 302 is energized with voltage. A charge application roller 303b-1 is provided on one side of the lower end of the adsorption conveyor belt 303b. The charge application roller 303b-1 is energized with a voltage of opposite polarity to that energized with the charge application frame 302. Metal adsorption plates 303b-2 are arrayed along the length of the outer belt surface of the adsorption conveyor belt 303b. The dust particles in the air entering the air intake duct 301 are charged by the charge application frame 302. Then, the charged dust enters the adsorption frame 303a area under the action of airflow, is captured by the metal adsorption plates 303b-2 with opposite charge, and is moved out of the air duct with the conveyor belt. This achieves continuous dust removal, prevents dust from clogging the fan 1 or adhering to the heat dissipation pipe inside the air-cooled pipe sleeve 2, and ensures the engine's heat dissipation efficiency and operational reliability.

[0022] Specifically, a set of charge application plates 302a are vertically fixed in an array within the charge application frame 302, perpendicular to the length of the air inlet duct 301. A set of inclined guide plates 302a-1 are respectively fixed in an array along the length of the air inlet duct 301 on both sides of the charge application plates 302a. The plates of the inclined guide plates 302a-1 are inclined at one end of the adsorption frame 303a. The inclined guide plates 302a-1 on the surfaces of each pair of adjacent charge application plates 302a are staggered. This structure effectively increases the charge application area, allowing the airflow to be fully ionized, making it easier for dust particles to become charged. Simultaneously, the staggered inclined guide plates 302a-1 guide the airflow to form vortices, prolonging the residence time of dust in the electric field, improving charging efficiency, and preventing dust escape due to direct airflow, thus ensuring the comprehensiveness and stability of the dust removal effect.

[0023] Furthermore, a charge neutralization roller 303b-3 is provided on the lower end of the adsorption conveyor belt 303b away from the charge application roller 303b-1. The charge neutralization roller 303b-3 is connected to a voltage of opposite polarity to that connected to the charge application roller 303b-1. After the adsorption conveyor belt 303b carries the dust out of the air duct, the charge neutralization roller 303b-3 can neutralize the charge on the metal adsorption plate 303b-2 on it, making the adsorbed dust easier to fall off or be collected. This realizes the automatic cleaning and charge reset of the adsorption conveyor belt 303b, ensuring its continuous adsorption capacity during recycling and avoiding dust accumulation that affects the operation of the conveyor belt or causes secondary pollution.

[0024] Furthermore, a diversion cone 303a-1 is provided at one end of the adsorption frame 303a near the charge application frame 302. Each diversion cone 303a-1 is respectively disposed between the two sides of each adsorption conveyor belt 303b. The pointed end of the diversion cone 303a-1 faces one side of the charge application frame 302. The width of the diversion cone 303a-1 is equal to the distance between the two sides of the adsorption conveyor belt 303b. The diversion cone 303a-1 can evenly disperse the airflow entering the adsorption area between each adsorption conveyor belt 303b, so that the airflow can fully contact the metal adsorption plate 303b-2.

[0025] Furthermore, a coarse filter 301c is fitted onto the end face of the air inlet duct 301 away from the fan 1; the coarse filter 301c can pre-filter out larger debris and particles in the air, preventing them from entering the air inlet duct 301 and causing blockage and damage to the charge application frame 302 or the adsorption component 303, thus extending the service life of the core dust removal components and reducing the maintenance frequency.

[0026] Furthermore, a set of air-cooled pipes 201 are installed inside the air-cooled pipe sleeve 2. The pipe axis of the air-cooled pipes 201 is parallel to the pipe axis of the air-cooled pipe sleeve 2. The end faces of each adjacent air-cooled pipe 201 are connected by a bend. One end of two air-cooled pipes 201 is bent to one side and passes through the air-cooled pipe sleeve 2. The air-cooled pipes 201 are used to circulate engine coolant. The multi-pipe parallel and bend design increases the heat dissipation area, and the bend connection forms a continuous flow channel to ensure efficient heat exchange between the coolant and the purified cold air, thereby quickly reducing the coolant temperature and ensuring that the engine operates within the optimal temperature range.

[0027] The operation process of this embodiment is as follows: The motors of fan 1 and dust removal component 3 are started. Fan 1 draws in air from one end of the air inlet duct 301. The air first passes through the coarse filter hood 301c for preliminary filtration of large particulate impurities, and then flows through the charge application frame 302. In the electrostatic field formed by the charge application plate 302a and the inclined guide plate 302a-1, the dust particles become charged. The charged dust enters the adsorption frame 303a area with the airflow, and is evenly distributed under the guidance of the diversion cone 303a-1, and is attracted by the oppositely charged particles. The metal adsorption plate 303b-2 captures the dust; the adsorption conveyor belt 303b moves cyclically under the drive of the belt shaft 301b, carrying the captured dust out of the air duct. When passing the charge neutralization roller 303b-3, the charge on the metal adsorption plate 303b-2 is neutralized, and the dust falls off; the purified air is blown by the fan 1 to the air-cooled pipe sleeve 2, and after exchanging heat with the coolant in the air-cooled pipe 201, it is discharged, thereby continuously providing efficient heat dissipation for the engine. At the same time, the entire dust removal process runs automatically and continuously without manual intervention.
