Description

Technical Field

[0001] The present invention relates to a temperature control system, a control method and a vehicle for a mobile crushing station, and belongs to the field of crushing station control systems. Background Art

[0002] For the existing mobile crushing station, before starting the engine, first open the ball valves of the heater pump water inlet pipeline and the oil suction pipeline. At this time, the ball valves of the urea tank water inlet and the engine oil suction port remain closed. Run the heater. Diesel enters the heater through the fuel pump and is ignited. At the same time, the heater pumps the coolant in the engine into the heating chamber of the heater and heats it. The circulation process of the coolant from the engine to the heater for heating and then back to the engine will preheat the engine. If a 15KW heater is used to heat a 1.3-ton engine, it takes about 20 minutes from -35°C to 30°C; after the engine preheating is completed, open the ball valves of the engine oil suction pipe and the urea tank, start the engine and let it run. After the engine starts running, turn off the heater and stop heating. Finally, close the ball valves of the heater pump water inlet pipeline and the oil suction pipeline.

[0003] The above heating method has the following problems:

[0004] 1) Only considering the extremely cold weather conditions, there is no temperature control plan for the crushing station in hot weather conditions;

[0005] 2) In extremely cold climate conditions, using -35# or -50# fuel, the fuel economy is poor;

[0006] 3) The prior art does not solve the temperature control problems of the feeder, screen and conveyor of the mobile crushing station;

[0007] 4) The battery has no heating device, and its charge and discharge performance is greatly reduced, and its life is attenuated.

[0008] 5) The low temperature environment cannot reduce dust and noise for the crushing station, and at the same time seriously affects the smoothness of the spray dust removal waterway. The prior art solutions do not solve the problem of dust reduction in extremely cold weather. Summary of the Invention

[0009] Aiming at the problems existing in the above prior art, the present invention provides a temperature control system, a control method and a vehicle for a mobile crushing station, which solve the problems that the temperature in special climates affects the stability of the operation of each working module of the crushing station and the low service life.

[0010] To achieve the above object, a temperature control system for a mobile crushing station adopted by the present invention includes:

[0011] An electric heating module, including a battery heating device for heating the battery and a vibrating feeder heating device for heating the vibrating feeder;

[0012] The liquid heating module includes a liquid fuel heater for separately heating a spray dust removal device, an engine, and a fuel tank;

[0013] The air heating module includes an air fuel heater for heating an electrical cabinet, and warm air blowers for heating a conveyor and a screening machine;

[0014] The electrical cabinet is respectively used to detect the temperatures of the fuel tank, the engine, and the battery. When the detected temperature is lower than the temperature threshold for the normal startup of the mobile crushing station, the electrical cabinet controls to turn on the air fuel heater to heat the electrical cabinet. At the same time, the electrical cabinet controls to turn on the liquid fuel heater to heat the engine, the fuel tank, and the spray dust removal device, and controls to turn on the battery heating device to heat the battery; when the electrical cabinet detects that the temperatures of the fuel tank, the engine, and the battery reach the normal startup temperature, the engine is started. The engine drives the generator to charge the battery. After the battery is fully charged, the electrical cabinet controls the vibrating feeder heating device to heat the vibrating feeder. At the same time, the battery turns on the warm air blowers to heat the conveyor and the screening machine.

[0015] As an improvement, the fuel tank includes a secondary fuel tank filled with -35# diesel and a main fuel tank filled with 0# diesel.

[0016] As an improvement, when the electrical cabinet detects through the engine temperature sensor that the engine temperature is lower than the temperature threshold for normal startup;

[0017] The electrical cabinet turns on the solenoid valve at the oil suction port of the secondary fuel tank, the oil circuit solenoid valve and the water circuit solenoid valve of the liquid fuel heater. The liquid fuel heater pumps -35# diesel from the secondary fuel tank for operation. The liquid fuel heater heats the engine coolant and the engine coolant circulates in the engine for heating; the liquid fuel heater heats the 0# diesel in the main fuel tank through the circulating water circuit; the liquid fuel heater heats the spray dust removal device through the circulating water circuit.

[0018] As an improvement, when the electrical cabinet detects through the battery temperature sensor that the temperature of the battery electrolyte is lower than -10°C, the electrical cabinet controls the battery heating device to pump -35# diesel from the secondary fuel tank for operation to heat the battery; the electrical cabinet controls the air fuel heater to pump -35# diesel from the secondary fuel tank for operation to continuously send warm air to the electrical cabinet.

[0019] As an improvement, when the electrical cabinet detects through the engine temperature sensor that the engine temperature reaches the temperature threshold for normal startup and the temperature of the battery electrolyte is heated to above -10°C, the engine of the mobile crushing station is started.

[0020] As an improvement, the electrical cabinet controls the electromagnetic directional valve connecting the engine and the fuel tank, so that the engine oil circuit leads to the secondary fuel tank or the main fuel tank through the electromagnetic directional valve.

[0021] As an improvement, the electromagnetic directional valve is a two-position two-way solenoid valve.

[0022] As an improvement, both the conveyor and the screening machine are provided with protective devices, and heat insulation materials are installed on the inner surfaces of the protective devices.

[0023] In addition, the present invention also provides a control method for the temperature control system of the mobile crushing station described above, including the following steps:

[0024] S1. When the temperature is lower than the temperature threshold for the normal start of the mobile crushing station, turn on the air-fuel heater air heating electrical cabinet, turn on the liquid fuel heater to heat the engine, fuel tank and spray dust removal device, and turn on the battery heating device to heat the battery;

[0025] S2. When the temperature of the battery electrolyte increases to above -10°C, there are no wax particles in the diesel in the fuel tank, and the engine temperature reaches the temperature at which it can be normally started, start the engine, and the engine drives the generator to charge the battery;

[0026] S3. After the battery is fully charged, turn on the vibrating feeder heating device to heat the vibrating feeder, and turn on the air heater to heat the ambient temperature inside the conveyor and the screening machine;

[0027] S4. When the mobile crushing station is in production operation, turn off the liquid fuel heater and rely on the engine cooling module to heat the circulating water circuit.

[0028] Finally, the present invention also provides a vehicle, on which the temperature control system of the mobile crushing station described above is installed.

[0029] Compared with the prior art, the temperature control system of the mobile crushing station of the present invention has the following beneficial effects:

[0030] (1) In extremely cold working conditions, the low temperature increases the viscosity of diesel or directly turns it into a waxy state. The diesel engine works by compression ignition, resulting in frequent failure of the engine start request. The present invention uses a liquid fuel heater to heat the engine and the fuel system, increasing the ambient temperature for the start of the mobile crushing station engine, reducing the viscosity of diesel in the fuel system, and enabling the engine of the mobile crushing station to still complete the start in a low-temperature environment.

[0031] (2) In extremely cold working conditions, the charge and discharge performance of the battery drops sharply. The lead-acid battery of the mobile crushing station has a charging capacity of 1 / 10 of that at room temperature and a discharge capacity of about 1 / 20 of that at room temperature in an environment of -41°C. The present invention uses a battery heating device to heat the battery, raising the temperature of the battery electrolyte to above -10°C or even 0°C, which can meet the normal use of the mobile crushing station in extremely cold climates and at the same time extend the service life of the battery.

[0032] (3) In extremely cold working conditions, the frozen soil carried by the ore will accumulate on the vibrating feeder, reducing the feeding efficiency of the vibrating feeder. The storage battery powers the heating device of the vibrating feeder. The present invention uses the heating device of the vibrating feeder to heat the vibrating feeder. The accumulated and blocked frozen soil is more likely to become loose during vibration excitation after being heated, ensuring the feeding speed of the vibrating feeder.

[0033] (4) In extremely cold working conditions, the frozen soil carried by the ore enters the screening machine and volumetrically blocks the screen mesh. The present invention uses the storage battery to power the warm air blower. The warm air blower raises the ambient temperature inside the screening machine. The blocked frozen soil is more likely to pass through the screen after the vibration excitation of the screening machine, ensuring the normal screening efficiency of the mobile crushing station in extremely cold environments.

[0034] (5) In extremely cold working conditions, the wear resistance of the rubber conveyor belt of the conveyor decreases, and the broken materials severely wear the rubber conveyor belt, reducing the service life of the rubber conveyor belt. The present invention uses a warm air blower to improve the ambient temperature in the conveyor and extend the replacement cycle of the rubber conveyor belt.

[0035] (6) In extremely cold working conditions, the water circuit of the spray dust removal device is easily blocked by broken ice. The present invention uses a liquid fuel heater to heat the water circuit and melt the broken ice in the water circuit, ensuring the dust removal function of the mobile crushing station.

[0039] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below. However, it should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0040] Unless otherwise defined, all technical terms and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] As Figure 1 、 Figure 2 shown, a temperature control system for a mobile crushing station includes:

[0042] The electric heating module includes a battery heating device for heating the battery and a vibrating feeder heating device for heating the vibrating feeder;

[0043] The liquid heating module includes a liquid fuel heater for heating the spray dust removal device, the engine and the fuel tank respectively;

[0044] The air heating module includes an air fuel heater for heating the electrical cabinet and a warm air blower for heating the conveyor and the screening machine;

[0045] The electrical cabinet is respectively used to detect the temperatures of the fuel tank, the engine and the battery. When the detected temperature is lower than the temperature threshold for the normal startup of the mobile crushing station, the electrical cabinet controls to turn on the air fuel heater for the electrical cabinet. At the same time, the electrical cabinet controls to turn on the liquid fuel heater to heat the engine, the fuel tank and the spray dust removal device, and controls to turn on the battery heating device to heat the battery; when the electrical cabinet detects that the temperatures of the fuel tank, the engine and the battery reach the normal startup temperature, the engine is started. The engine drives the generator to charge the battery. After the battery is fully charged, the electrical cabinet controls the vibrating feeder heating device to heat the vibrating feeder. At the same time, the battery turns on the warm air blower to heat the conveyor and the screening machine.

[0046] As Figures 1 to 3 shown, a control method for the temperature control system of a mobile crushing station includes the following steps:

[0047] 1) After the mobile crushing station is powered on, the electrical cabinet in the temperature control system automatically detects the temperatures of the engine, the fuel tank and the battery:

[0048] 2) In extremely cold weather, when the electrical cabinet is connected to the engine temperature sensor and the electrical cabinet detects through the engine temperature sensor that the engine temperature is lower than the temperature threshold for normal startup, the electrical cabinet turns on the solenoid valve at the oil suction port of the auxiliary fuel tank, the solenoid valve for the oil circuit of the liquid fuel heater and the solenoid valve for the water circuit. The liquid fuel heater pumps -35# diesel from the auxiliary fuel tank to work. The liquid fuel heater heats the engine coolant and the engine coolant circulates in the engine for heating; the liquid fuel heater heats the 0# diesel in the main fuel tank through the circulating water circuit; the liquid fuel heater heats the spray dust removal device through the circulating water circuit;

[0049] 3) When the electrical cabinet is connected to the battery temperature sensor and the electrical cabinet detects through the battery temperature sensor that the temperature of the battery electrolyte is lower than -10°C, the battery heating device pumps -35# diesel from the auxiliary fuel tank to work, so that the battery heating device heats the battery; the air fuel heater pumps -35# diesel from the auxiliary fuel tank to work and continuously sends warm air to the electrical cabinet;

[0050] 4) When the electrical cabinet detects through the engine temperature sensor that the engine temperature reaches the temperature threshold for normal startup and the battery electrolyte temperature is heated above -10°C, start the engine of the mobile crushing station;

[0051] 5) The electrical cabinet controls the electromagnetic directional valve connected to the engine and the fuel tank. The electromagnetic directional valve is a two-position two-way solenoid valve. The engine oil circuit passes through the electromagnetic directional valve and leads to the auxiliary fuel tank, and -35# diesel is pumped in for operation. At this time, the electrical cabinet closes the liquid fuel heater and its oil circuit solenoid valve; the water circuit of the engine cooling module is connected to the spray dust removal device and the fuel tank. After the engine starts, the heating circulating water circuit is driven by the engine cooling module. When the 0# diesel in the main fuel tank melts into an available fluid and the electrical cabinet detects through the fuel tank temperature sensor that the oil temperature in the main fuel tank is stable above 5°C, the electrical cabinet transfers the connection of the electromagnetic directional valve to the main fuel tank;

[0052] 6) The engine is connected to the generator. The generator works to charge the battery. The generator is connected to the heating device of the vibrating feeder and the warm air blower. The heating device of the vibrating feeder is installed at the bottom of the vibrating feeder and can continuously heat. The warm air blower is connected to the conveyor and the screening machine and continuously sends warm air. Both the conveyor and the screening machine are equipped with protective devices, and heat insulation materials are installed on the inner surface of the protective devices.

[0053] In addition, for the temperature control system of the mobile crushing station of the present invention, in hot weather conditions, the warm air blower turns off the electric heating module, and by continuously sending air, the hot air inside the conveyor and the screening machine is taken out, which can effectively prevent the abnormal high temperature of the conveyor motor and the vibrator of the screening machine. The temperature control system of the present invention can ensure that the mobile crushing station can perform normal and efficient crushing and screening operations in extremely cold and hot mining areas.

[0054] Finally, the present invention also provides a vehicle equipped with the above-mentioned temperature control system of the mobile crushing station.

[0055] In addition, those skilled in the art can understand that although some of the embodiments described herein include certain features contained in other embodiments rather than other features, the combination of features of different embodiments also means that it is within the protection scope of the present invention and forms different embodiments. For example, in the above embodiments, those skilled in the art can use them in combination according to the known technical solutions and the technical problems to be solved by the present application.
