Description

Technical Field

[0001] The utility model belongs to the technical field of drying equipment, and particularly relates to a louver-type cold and hot air conversion three-way structure. Background Art

[0002] Drying equipment, also known as drying equipment or Dryingequipment, is a combination of mechanical equipment that removes moisture or other liquids from the surface of materials through specific technical means. This type of equipment is widely used in different industries, such as mineral processing, building materials, metallurgy, chemical industry, printing, food processing, etc. It is used to dry various materials with a certain humidity or particle size. The working modes of drying equipment are diverse, including but not limited to hot air drying, indirect heat transfer drying, steam drying, ultraviolet drying, infrared drying and electromagnetic drying.

[0003] The design and structure of drying equipment vary. For example, rotary dryers are widely used because they can adapt to a variety of materials. In the field of food and agricultural product processing, special drying equipment designed and manufactured according to specific product characteristics and process requirements is often used, such as special dryers for dehydrating and drying vegetables and fruits.

[0004] In general, the main purpose of drying equipment is to improve production efficiency, reduce the moisture content of materials to facilitate subsequent storage, transportation or further processing, and ensure that the products meet the required quality standards.

[0005] With the development of the times, drying equipment is used more and more widely. Drying equipment has also developed from the initial single function to multi-functional intelligence. From the perspective of energy saving and time saving, when drying is about to end, the drying equipment can enter the cold air most efficiently, which can make the grain cool down evenly and quickly and shorten the warehousing time. The existing drying equipment lacks a structure for quickly introducing cold air when drying is about to end. Generally, it is cooled after being exported from the drying equipment. Therefore, we hope to design a three-way structure with a new structure for hot and cold air conversion to solve this problem. Utility Model Content

[0027] See also Figures 1 to 5 The utility model provides a technical solution: a shutter-type cold and hot air conversion three-way structure, comprising: a three-way box 200, an adjustable cold air door 100 and an adjustable hot air door 300, an adjustable hot air box 310 for introducing hot air is installed on the right side of the three-way box 200, and an adjustable cold air door 100 for introducing cold air is installed on the lower side of the three-way box 200;

[0028] The adjustable cold air door 100 includes a cold air box 110, a cold air door blade 120 and a driving member 130. The driving member 130 is movably installed at the front of the lower end of the cold air box 110.

[0030] See also Figures 1 to 4 A connecting flange 210 is provided on the left side of the three-way box 200, and the left end of the three-way box 200 is sealed and connected to the air inlet of the drying equipment through the connecting flange 210.

[0031] The right end of the three-way box 200 is connected to the left end of the hot air box 310, and the right end of the hot air box 310 is designed to be open. The lower end of the three-way box 200 is connected to the upper end of the cold air box 110, and the lower end of the cold air box 110 is designed to be open. The setting of the three-way box 200, in conjunction with the adjustable cold air door 100 and the adjustable hot air door 300, can promptly let the corresponding air into the three-way box 200 when cold air or hot air is needed, thereby achieving timely cooling of the grain that is about to be dried in the drying equipment.

[0032] As the first embodiment of the utility model, in actual use, during normal drying, the multiple hot air door blades 320 on the adjustable hot air door 300 are opened, and the hot air in the hot air manufacturing equipment enters the three-way box 200 through the adjustable hot air door 300, and then enters the drying equipment to perform drying. At this time, the multiple cold air door blades 120 on the adjustable cold air door 100 are in a closed state. When the drying of grain in the drying equipment is about to be completed, the multiple cold air door blades 120 on the lower side of the adjustable cold air door 100 are opened by the driving member 130, and the multiple hot air door blades 320 on the adjustable hot air door 300 are closed synchronously by the driving member 2 330, and the external cooling air quickly enters the three-way box 200 through the adjustable cold air door 100, and then enters the drying equipment to evenly and quickly cool down the grain that is about to be dried, thereby greatly shortening the warehousing time of the grain.

[0033] See also Figure 5 The driving member 130 includes a handle 131, an eccentric wheel 132, a connecting rod and a synchronization rod 134. The middle of the handle 131 near the front end of the cold air box 110 is fixedly connected to the outer center of the eccentric wheel 132. The eccentric wheel 132 is rotatably mounted on the front inner wall of the cold air box 110. In actual use, the structure of the driving member 130 is similar to that of the driving member 330. The length of the synchronization rod 134 and the number of the fixing plates 135 on the driving member 330 are set as needed, and its working principle is the same as that of the driving member 130.

When the driving member 130 needs to work, the cylinder pushes or pulls the handle 131 of the driving member 130 (the cylinder can be connected to any end of the handle 131 as needed, and its push and pull can be determined according to the installation direction of the cylinder. The following assumes that the cylinder extends to push the driving member 130 to start, and contracts to close). As the cylinder pushes or pulls, The handle 131 rotates clockwise or counterclockwise, thereby driving the eccentric wheel 132 to rotate clockwise or counterclockwise, and the eccentric wheel 132 drives the connecting rod to move, thereby causing the synchronization rod 134 to move down or reset. When the synchronization rod 134 moves down, it can pull multiple fixed plates 135 to rotate synchronously, thereby causing multiple cold air door blades 120 to rotate, that is, opening the adjustable cold air door 100, otherwise it is closed, thereby realizing the closing and opening of the adjustable cold air door 100, and the structure of the second driving member 330 is similar to that of the first driving member 130, and the working principle is the same, so that the entire device can meet the needs of timely ventilation of hot air or cold air, and the entire device has a simple structure and low cost.
