Description

Control device for air duct of preheating room

Technical Field

The utility model relates to a medical instrument sterilizing installation field especially relates to a preheat room wind channel controlling means.

Background

Before the medical apparatus is sterilized by ethylene oxide, the medical apparatus to be sterilized is firstly placed in a preheating room for preheating, in order to improve the preheating effect, constant temperature needs to be ensured in the preheating room, an air inlet is usually arranged at the top of the preheating room, a return air inlet is usually arranged on the side wall of the preheating room, hot air blown in by a hot air blower forms hot air circulation between the top air inlet and the side wall return air inlet, namely, a heating mode of top air inlet and side return air is adopted, but the heating mode has the defect of unreasonable indoor air flow organization, so that a local area in the preheating room is dead-angled, the preheating effect of products arranged in the area is influenced, and if the condition of the local dead-angled area is to be avoided, only the air inlet/return speed can be increased, so that the working environment of the preheating room is in a positive pressure state, and the running cost of matched equipment such as the hot air blower can be improved under, the long-term economic burden is also brought to the using unit.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the main technical problem who solves provides a preheat room wind channel controlling means, can solve the above-mentioned defect that the room air duct system exists of preheating now.

In order to solve the technical problem, the utility model discloses a technical scheme be: provided is a pre-heating room air duct control device, including: the hot air blower comprises a hot air blower, a static pressure box, an air inlet channel and a return air channel, wherein the air inlet channel is arranged at the top of the hot pre-heating room, the return air channel is arranged at the bottom of the pre-heating room, the hot air blower is arranged above the air inlet channel, the static pressure box is arranged below the return air channel, and the hot air blower inputs hot air into the pre-heating room and forms vertical convection between the air inlet channel and the return air channel.

In a preferred embodiment of the present invention, the air inlet passages have a plurality of groups, and are uniformly distributed on the top of the preheating room.

In a preferred embodiment of the present invention, the air return channel has a plurality of sets, and the sets are arranged below the air inlet channel.

The utility model has the advantages that: through offering inlet air duct at preheating the room top, the structural style of air-out passageway is offered to the bottom, make hot-blast formation perpendicular convection current between inlet air duct and air-out passageway, adopt the air supply/return air mode of going up down to return promptly, can avoid appearing the low temperature dead angle region, simultaneously through installing the static pressure case in air-out passageway below, can reduce the hot-blast machine noise, can obtain even static pressure return air again, reduce the dynamic pressure loss, thereby it is fast to make the interior temperature of preheating the room, the low temperature dead angle region can not appear, thereby can improve the preheating efficiency to the product, and reduce the energy consumption, practice thrift enterprise economic cost.

Drawings

Fig. 1 is a schematic structural view of a preferred embodiment of an air duct control device of a preheating room according to the present invention;

the parts in the drawings are numbered as follows: 1. preheating room, 2, inlet air channel, 3, return air channel.

Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 1, an embodiment of the present invention includes:

a pre-heated room air duct control apparatus comprising: air heater, static pressure case, inlet air duct 2 and return air passageway 3, inlet air duct 2 sets up at hot prefabricated house 1's top, return air passageway 3 sets up in the bottom of preheating room 1, the air heater is installed inlet air duct 2's top is used for to preheating room 1 and carry hot-blastly, static pressure case is installed in return air passageway 3 below for reduce the noise of air heater, can reduce simultaneously and preheat the interior dynamic pressure loss in room 1, obtain even static pressure return air. The utility model discloses structural design makes the air heater to preheat the hot-blast formation perpendicular convection current between inlet air duct 2 and return air passageway 3 of room 1 internal input, can improve the rate of rising temperature in preheating room 1, also can avoid appearing local low temperature dead angle simultaneously.

In the embodiment, a plurality of groups of air inlet channels 2 are uniformly distributed on the top of the preheating room 1; the return air channels 3 are also provided with a plurality of groups, and are correspondingly arranged below the air inlet channels 2 in pairs. Therefore, hot air output by the air heater forms multiple groups of vertical convection between the air inlet channel 2 and the air return channel 3, the temperature rise speed of the preheating room 1 is increased, and the indoor temperature and the indoor pressure are ensured to be uniform.

The utility model discloses a preheat room wind channel controlling means adopts the air supply/return air mode of going up down to return, can avoid appearing low temperature blind spot region, simultaneously through at air-out passageway below installation static pressure case, can reduce the hot-air blower noise, can obtain even static pressure return air again, reduces the dynamic pressure loss to the messenger preheats the indoor temperature and heaies up soon, low temperature blind spot region can not appear, thereby can improve the preheating efficiency to the product, and reduce the energy consumption, practice thrift the economic cost of enterprise.
