Description

Technical Field

[0001] This utility model relates to the field of freeze dryer technology, and in particular to a dustproof freeze dryer. Background Technology

[0002] Refrigerated dryers generate heat during operation, requiring large ventilation holes. However, existing refrigerated dryers lack dustproofing, allowing airborne dust to enter the equipment through the inlet, outlet, and ventilation holes. Over time, this dust accumulates inside, affecting drying efficiency, increasing energy consumption, and wasting resources. Furthermore, excessive dust buildup can easily cause malfunctions in delicate internal components, damaging the equipment and shortening its lifespan.

[0003] Chinese Patent Announcement No.: CN 213300642 U, Announcement Date: May 28, 2021. This utility model proposes a dustproof freeze dryer, including a casing and a dustproof mechanism. The casing has an air inlet and an air outlet on both sides. An adsorption strip is provided along the outer edge of both the air inlet and outlet. Adsorption magnetic blocks are evenly distributed on the adsorption strip. The dustproof mechanism includes a through mounting base, a dustproof net, and an electrostatic precipitator housed within the mounting base. A support base is provided at the bottom of the casing. Adsorption blocks corresponding to the adsorption magnetic blocks are evenly distributed on one side of the mounting base. The shortcomings of this technical solution are: the dustproof net accumulates dust and impurities, affecting the smoothness of airflow; disassembly, cleaning, and maintenance are cumbersome, making it difficult to maintain smooth airflow.

[0004] In summary, existing freeze dryers have shortcomings such as dustproof structures affecting machine operation and difficulty in cleaning and maintenance. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of existing freeze dryers, such as the dustproof structure affecting machine operation and difficulty in cleaning and maintenance, and provides a dustproof freeze dryer that is easy to clean and maintain, and ensures smooth airflow and machine operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A dustproof freeze dryer, comprising The body is equipped with air vents; Mounting bracket, which is connected to the unit body, with the air vent placed inside the mounting bracket; Dustproof mesh panel, dustproof mesh panel and mounting frame are detachable and connected; Dust removal brushes are placed on both sides of the dustproof mesh plate. The dust removal brushes are movably connected to the mounting frame and to the dustproof mesh plate. The flushing baffle is placed inside the dustproof mesh plate and is movably connected to the mounting frame.

[0007] Airflow is delivered through vents on the machine body. A mounting bracket is installed close to the vents, and a dustproof mesh plate is connected to the bracket to cover the vents, preventing dust and impurities from entering and accumulating inside the machine, thus avoiding dust buildup that could affect the freeze dryer's operation. Dust-collecting brushes are installed on both sides of the dustproof mesh plate, allowing for efficient and convenient dry brushing to remove dust and prevent dust accumulation that could obstruct airflow. A flushing baffle is connected to the inner side of the dustproof mesh plate, blocking the vents and facilitating direct water washing with the dust-collecting brushes for cleaning, maintaining both dust prevention and efficient cleanliness. This achieves the effects of ensuring efficient dust prevention, rapid cleaning and maintenance, unobstructed airflow, and ensuring the freeze dryer maintains high-efficiency operation.

[0008] Preferably, the dustproof mesh panel includes a fixed frame and a dustproof mesh sheet, with the dustproof mesh sheet connected to the inner wall of the fixed frame. The sides of the dustproof mesh sheet are connected to the fixed frame to facilitate assembly, replacement, and maintenance of the dustproof mesh panel via the fixed frame. This improves the ease of assembly of the dustproof mesh panel.

[0009] Preferably, two mounting brackets are provided, symmetrically arranged on both sides of the air vent. Each mounting bracket has a fixing slot, and the fixing frame is inserted into the fixing slot. Having two mounting brackets on both sides of the air vent allows the fixing frame to be installed by inserting it into the fixing slot, thus positioning and fixing the dustproof mesh panel. This improves the installation efficiency and stability of the dustproof mesh panel.

[0010] Preferably, the lower end of the mounting bracket is connected to a base plate, and the upper end of the mounting bracket has an insertion hole for inserting a limiting plate. The lower end of the mounting bracket supports the dustproof mesh panel from below via the base plate, and the upper end of the mounting bracket has an insertion hole for installing the limiting plate. This limits the dustproof mesh panel from above and prevents dust from falling onto it, thus securing the dustproof mesh panel during installation. Simultaneously, moving the limiting plate facilitates the removal of the dustproof mesh panel. This achieves improved dustproof effectiveness and enables efficient assembly and maintenance.

[0011] Preferably, the mounting frame is equipped with a guide groove, and the dust-removing brush is connected to a slider. The slider is slidably connected to the guide groove. The mounting frame also has a side groove that communicates with the guide groove, and a control block is slidably connected to the side groove. The control block is connected to the slider. The mounting frame contains a guide groove, and the dust-removing brush moves along the guide groove via the slider, stabilizing itself on the dustproof mesh for cleaning. The slider ensures stable contact between the dust-removing brush and the dustproof mesh. The control block, connected to the slider, allows for up-and-down movement of the dust-removing brush from the outside of the mounting frame, thus achieving the cleaning operation. This improves the efficiency of dust-proof cleaning operations.

[0012] Preferably, the dust-removing brush includes a connecting plate and brush bristles. One side of the brush bristles is connected to the base plate, and the other side abuts against the dustproof mesh. The connecting plate is connected to a slider. The brush bristles are attached to the connecting plate and then to the slider, ensuring the movement of the brush bristles and the depth of contact with the dustproof mesh. This prevents insufficient contact from reducing dust removal efficiency or causing the brush to dry-brush, thus ensuring effective dust removal and cleaning.

[0013] Preferably, one side of the mounting bracket has a placement hole, and the other side has a docking groove. The docking groove is arranged opposite to the placement hole, and the flushing baffle is inserted into the placement hole. On one of the two mounting brackets, the flushing baffle can be placed through the placement hole. The flushing baffle can be pulled to fully expose the air vent or pulled into the docking groove to completely cover the air vent, thus ensuring that airflow is not obstructed during the operation of the freeze dryer. During flushing or when the machine is not turned on for extended periods, it completely protects the air vent from liquid impurities. This achieves convenient operation and connection of the flushing baffle and improves overall dust protection.

[0014] Preferably, the flushing baffle is connected to a limiting strip, the size and position of which are adapted to the mating groove. The limiting strip is connected to the side of the flushing baffle to prevent it from falling out of the insertion hole during operation, thus avoiding repeated reassembly and improving the stability of the connection with the mating groove. This achieves the effect of improving the operational and installation stability of the flushing baffle.

[0015] The beneficial effects of this utility model are: ensuring efficient dust protection for the freeze dryer; enabling rapid cleaning and maintenance; maintaining smooth airflow; ensuring the freeze dryer maintains efficient operation; improving the ease of structural assembly; improving the installation efficiency and stability of the structure; improving the ease of operation and connection of the structure; improving the comprehensiveness of dust protection; ensuring the effectiveness of dust protection and cleaning operations; and improving the operational and installation stability of the structure.
