Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sterilization cabinet, specifically is a kind of air intake structure of sterilization cabinet. BACKGROUND

[0002] Steam sterilization is the main way of edible fungus base sterilization, and whether sterilization is complete determines the success or failure of edible fungus production. At present, the cap type automatic air intake device is generally used to complete the production of sterilization cabinet equipment in China. Its working principle is that after the cap valve is lifted, steam enters the sterilization cabinet through the steam pipeline, and the steam pressure lifts the cap in the cabinet, and the steam enters the sterilization cabinet.

[0003] Because it is lifted by pipeline natural pressure, steam enters instantaneously, which causes the temperature of the air inlet position to suddenly increase, and the mushroom bag above the position is easy to melt or carbonize internally. The air intake is uneven at each position in the cabinet body, and the temperature difference of each point is too large, which affects the production process, and a large amount of steam is also wasted during the heating process. Thus, the production yield is low (about 85-90%), resulting in high cost. In addition, if the air intake is too small, the sterilization is not complete, and the mushroom bag is prone to mold during the later cultivation process. If the air intake is too large, the mushroom bag will be carbonized internally, resulting in a serious loss of nutrients in the mushroom bag, which affects the growth of the mushroom bag mycelium in the later cultivation room. Some manufacturers now use traditional round pipe type air intake devices. Although the uniformity of air intake has changed, the device only improves the air intake method, and a large amount of condensed water is generated in the pipe during use, causing water resistance. In addition, the pipe is often deformed by the rear wheels of the forklift during use, affecting the air intake effect, and still cannot meet the production and market requirements of the sterilization cabinet. Therefore, an air intake structure of a sterilization cabinet is proposed. UTILITY MODEL CONTENTS

[0028] In order to facilitate the air supply communication of air inlet pipe seat 1, air inlet hole is penetrated and arranged at the rear portion of air inlet pipe seat 1, specifically, as shown in the drawing, Figure 5 The length of A section air inlet pipe seat 1 is 3170mm, the position of air inlet hole is at 1120mm, and the specification of air inlet hole is 60mm round mouth. Similarly, the length of B section air inlet pipe seat 1 is 4870mm, the length of C section air inlet pipe seat 1 is 4835mm, and the length of D section air inlet pipe seat 1 is 3165mm. The air inlet is arranged at the position shown in the drawing, and the circular ring communication seat 3 is oppositely welded and installed at the rear opening side of air inlet hole, for butt joint installation with air inlet interface. After installation, the air inlet interface is oppositely inserted and installed with the through hole in the middle of circular ring communication seat 3, air inlet pipe seat 1 is communicated and installed with the air inlet interface in sterilization cabinet through circular ring communication seat 3 to realize air supply communication. In order to improve the connection sealing property, sealing ring pad 7 made of high-temperature-resistant rubber material is fixedly installed at the rear portion of circular ring communication seat 3.

[0029] In order to facilitate steam discharge, steam outlet hole 4 is arranged at the upper and lower sides of air inlet pipe seat 1, specifically, as shown in the drawing, Figure 2As shown, the steam outlet holes 4 are provided with multiple steam outlet holes 4, the opening size of the steam outlet holes 4 is 8mm, and the steam outlet holes 4 are uniformly and equidistantly arranged through the upper and lower middle parts of the air inlet pipe seat 1.

The middle boss 5 is arranged in a protruding manner inside the air inlet pipe seat 1. The lower steam outlet hole 4 is arranged through the middle part of the middle boss 5, so that the steam outlet hole 4 is in an upper protruding state, which can effectively reduce the risk of blockage of the steam outlet hole 4.

After being guided, the steam is uniformly discharged from the steam outlet holes 4 on the upper and lower sides of the air inlet pipe seat 1 into the interior of the sterilization cabinet, and the material in the sterilization cabinet is subjected to high-temperature sterilization by the steam. When the steam is condensed due to the temperature difference of the side wall of the air inlet pipe seat 1, the condensed water flows into the flow guide grooves formed on both sides of the middle boss 5 through the inner wall of the air inlet pipe seat 1. The lateral flow effect of the steam during cooperation makes the water flow to both sides in the flow guide grooves. Finally, the water is discharged from the liquid discharge opening 6 of the end cover 2 on both sides, which can effectively avoid the blockage of the lower steam outlet hole 4 by water, and make the steam discharge more stable.
