Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 3, a preheating device for use in a dust removing apparatus comprises a dust collection box 1, an inlet is provided at one side of the dust collection box 1 and an outlet is provided at the other side of the dust collection box 1, a pipe 2, one end of the pipe 2 is connected to the inlet and the other end of the pipe 2 is connected to the outlet; the heating device 3 is arranged on the pipeline 2 and used for heating the gas in the pipeline 2; and the airflow flowing device 4 is arranged on the pipeline 2 and is used for the airflow in the pipeline 2 to flow in a preset direction.
In the invention, the preheating device preheats the box body in advance before the dust removing equipment is started, thereby avoiding condensation. In the preheating process, the heating device 3 is started, then the air in the pipeline 2 and the dust collection box body 1 is driven to circularly flow through the airflow flowing device 4, the internal temperature reaches a preset value, then the preheating device is closed, and the dust removal equipment is started. The advantage of preheating in advance is that, inside temperature is high enough, can avoid the production of condensation, avoids dust bonding, filter bag to block up.
The preheating is realized by circulating air flow through the dust collection box body 1 and the pipeline 2, so that the temperature in the dust collection box body 1 can be quickly raised.
Specifically, the inlet and the outlet are provided at the middle position of the dust suction case 1. The dust collection box body is arranged in the middle, so that the entering heat can be blown into the whole dust collection box body 1 as far as possible, and the temperature of the dust collection box body 1 can be raised as soon as possible.
In particular, the pipe 2 is provided with a valve 5 near both the inlet and near the outlet ends. After stopping preheating, block up the both ends of pipeline 2 through valve 5, avoid after the dust equipment starts, inside dust enters into pipeline 2 and deposits. The inlet and outlet are as far away from each other as possible.
In particular, the valve 5 is a solenoid valve. The electromagnetic valve can be electrically controlled to be closed or opened, and is convenient. Alternatively, other forms of valve 5 may be used, such as a manual ball valve. So long as it can be used to close the pipe 2.
Specifically, the heating device 3 includes a plurality of heating pipes 31 and a heating shell 32, the shell is fixedly connected to the pipeline 2, and the heating pipes 31 extend into the shell. The heating housing 32 communicates with the duct 2, and when the heating duct 31 is heated, air can be rapidly heated while passing through the heating duct 31. The heat is then transferred to the dust removal box via conduit 2. Further, a heat insulation material is fixed on the surface of the pipeline 2. The heating device 3 may be replaced with a spiral high-frequency heating pipe 31. Further, the surface of the heating pipe 31 is provided with fins.
Specifically, the airflow flowing device 4 is an air pump or a fan. The air flow is driven by the air pump or the fan to flow rapidly. The airflow flowing device 4 may be a blower.
Specifically, the air supply device 6 is connected to the pipeline 2, the air supply device 6 comprises an air blower 61 and a heating part 62, the heating part 62 is communicated with the pipeline 2, and the air blower 61 is connected to the heating part 62. When the internal air flow velocity is too slow, it is gaseous to inside impact through air supplement unit 6, makes inside atmospheric pressure increase, at the filling-in-process, then blows in the air and through heating member 62 through air-blower 61, through heating member 62 to the air heating, when sending into the heat, increase inside wind pressure. Enough air flow is provided at the air flow device 4, and when passing through the heating device 3, a large amount of air also passes through, so that the internal temperature rise is accelerated.
