Description

Technical Field

[0001] The utility model relates to the technical field of edible fungus breeding equipment, in particular to a purification device for air conditioning ventilation ducts used for edible fungus breeding. Background Art

[0002] Edible fungi are large fungi that can be eaten by humans. Specifically, edible fungi are edible mushrooms. Mushrooms refer to a type of large fungi that can form large fleshy (or gelatinous) fruiting bodies or sclerotium-like tissues and can be eaten or used as medicine.

[0003] When cultivating edible fungi, extra attention should be paid to the requirements of the cultivation environment. The cultivation temperature should be stable at around 25°C. Usually, ventilation and air conditioning are installed in the greenhouse for cultivating edible fungi. On the one hand, the internal temperature can be adjusted, and on the other hand, the air inside the greenhouse can be replaced. In order to ensure the quality of air entering the edible fungi greenhouse, purification devices are installed in the air conditioning ventilation ducts. Conventional purification devices include filter screens, activated carbon bags, ultraviolet sterilization lamps, photocatalytic devices, active decomposition equipment, antibacterial filter cotton boards, etc., to physically filter and purify the airflow and biologically purify it. Among them, the antibacterial filter cotton board mainly filters the dust and bacteria in the airflow and inhibits the growth of bacteria. It is often used in air conditioning ducts;

[0004] However, the purification equipment in the air conditioner in the existing edible fungus breeding greenhouse has some defects, such as:

[0005] When multiple layers of antibacterial filter cotton are arranged front and back in the pipeline, the first layer of antibacterial filter cotton is usually used for filtering. The quality of the airflow filtered by the first layer of antibacterial filter cotton is higher, and there is less dust in the airflow. Then, when the airflow passes through the following layers of antibacterial filter cotton, the following layers of antibacterial filter cotton basically do not need to filter the airflow. Therefore, the use time of multiple layers of antibacterial filter cotton is not equal, and the multiple layers of antibacterial filter cotton cannot be used for the same period of time, which leads to the damage rate of the first layer of antibacterial filter cotton being higher than that of other antibacterial filter cottons. Summary of the invention

[0006] The utility model provides a purification device for air conditioning ventilation ducts used for edible fungus cultivation, so as to solve the problems raised in the above-mentioned background technology.

[0007] The technical solution of the utility model is achieved in this way:

[0008] A purification device for an air conditioning ventilation duct for edible fungus cultivation, comprising a housing, a lifting plate, an antibacterial filter cotton plate and a screw;

[0009] Shell: a rectangular array of antibacterial filter cotton plates rotates inside the shell, and a power component is installed on the upper end of the shell;

[0010] Screw: The lower end of the screw is fixed to the upper center of the antibacterial filter cotton plate, and the upper end of the screw is fixed to the output end of the power component, and the power component drives the screw to rotate;

[0011] Lifting plate: the lifting plate is inserted into the upper end of the shell in an upward and downward motion, the screw thread passes through the lifting plate, the number of the lifting plates is equal to the number of rows of antibacterial filter cotton plates and the lifting plates are arranged in a linear array in the shell, and each lifting plate is located above a row of antibacterial filter cotton plates;

[0012] By adopting the above technical scheme, when the outer shell is fixed in the ventilation duct, the antibacterial filter cotton board filters the airflow, and when the power assembly drives the screw to rotate, the screw drives a whole row of antibacterial filter cotton boards to rotate on the one hand, so that the front row of antibacterial filter cotton boards do not perform filtering work after filtering for a long time, so that the back row of antibacterial filter cotton boards can filter, thereby allowing multiple rows of antibacterial filter cotton boards to rotate for filtering and purification work, and the screw drives the lifting plate to move up on the other hand, so that the lifting plate no longer hinders the airflow from the top of the front row of antibacterial filter cotton boards to the back row of antibacterial filter cotton boards, thereby expanding the airflow flow area and avoiding the front row of antibacterial filter cotton boards from hindering the airflow flow speed, thereby allowing multiple rows of antibacterial filter cotton boards to rotate for filtering work while ensuring the airflow flow speed.

[0013] Preferably, the power assembly includes a motor, a transmission wheel, a transmission belt and a pressure wheel, the motor is fixed to the side of the shell, the output end of the motor and the upper end of the screw are both fixed with a transmission wheel, a transmission belt is sleeved between a row of transmission wheels and connected by transmission belt transmission, the pressure wheels rotate in groups on the upper side of the shell and two are in a group, each group of pressure wheels is located between two adjacent transmission wheels in the same row, and two opposite sides of the transmission belt are sandwiched between the two pressure wheels in each group;

[0014] By adopting the above technical solution, the motor drives one of the transmission wheels to rotate, and the transmission wheel drives the other transmission wheels to rotate through the transmission belt. The transmission wheel is the output end of the power assembly, so that the other transmission wheels drive the screw to rotate, and the pressure wheel clamps the transmission belt, forcing the transmission belt to fit tightly against the transmission wheel, increasing the contact angle between the transmission belt and the transmission wheel, and ensuring that the transmission belt stably drives the transmission wheel to rotate. In summary, the power assembly provides stable power for the rotation of the screw.

[0015] Preferably, an inner mounting frame is movably passed through the shell laterally, and the inner mounting frame is fixed in the shell by screws. The number of the inner mounting frames is equal to the number of rows of antibacterial filter cotton plates, and a row of antibacterial filter cotton plates rotates in the shell by rotating in the inner mounting frame;

[0016] By adopting the above technical solution, the antibacterial filter cotton board is rotated in the outer shell by rotating the inner mounting frame. When all the antibacterial filter cotton boards need to be replaced, the inner mounting frame can be removed for replacement, that is, the antibacterial filter cotton board can be easily replaced by separating the inner mounting frame from the outer shell.

[0017] Preferably, a connecting rod is fixed to the rotation center of the upper end of the antibacterial filter cotton plate, the connecting rod rotates through the upper end of the inner mounting frame, the antibacterial filter cotton plate rotates in the inner mounting frame through the connecting rod, and the connecting rod moves upward and penetrates the lower end of the screw rod so that the antibacterial filter cotton plate is fixed to the screw rod;

[0018] By adopting the above technical solution, the connecting rod is inserted upward into the screw rod, and when the screw rod rotates, the connecting rod and the antibacterial filter cotton plate can still be driven to rotate. When the inner mounting frame and the antibacterial filter cotton plate need to be removed, the connecting rod can be laterally removed from the screw rod without affecting the withdrawal of the inner mounting frame, which is convenient to use.

[0019] Preferably, the antibacterial filter cotton plates have three rows, the middle row of antibacterial filter cotton plates are offset from the front and rear rows of antibacterial filter cotton plates in the horizontal plane, the middle antibacterial filter cotton plate is located directly behind the middle of the two adjacent antibacterial filter cotton plates in the front row, and the middle antibacterial filter cotton plate is located directly in front of the middle of the two adjacent antibacterial filter cotton plates in the rear row;

[0020] By adopting the above technical solution, when the front row of antibacterial filter cotton plates are turned away, the airflow flows directly from between two adjacent antibacterial filter cotton plates to the rear row of antibacterial filter cotton plates, ensuring that the airflow directly contacts the antibacterial filter cotton plates.

[0021] Preferably, sterilization lamps are arranged in a linear array at both lateral ends of the housing, and a row of antibacterial filter cotton plates is located between two adjacent sterilization lamps in front and behind;

[0022] By adopting the above technical solution, the sterilization lamp can sterilize the antibacterial filter cotton plate and the inner cavity of the shell with ultraviolet light to avoid excessive internal dust and promote bacterial growth.

[0023] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0024] In the utility model, the shell is fixed in the ventilation duct to fix the device in the ventilation duct, and the antibacterial filter cotton plate filters the airflow. When the power component drives the screw to rotate, the screw drives a whole row of antibacterial filter cotton plates to rotate on the one hand, so that the front row of antibacterial filter cotton plates do not perform filtering work after filtering for a long time, so that the rear row of antibacterial filter cotton plates can filter, so that multiple rows of antibacterial filter cotton plates can be rotated to perform filtering and purification work, ensuring that the use time of multiple rows of antibacterial filter cottons is equal and the degree of damage tends to be equal, which is more conducive to one-time maintenance and replacement of all antibacterial filter cotton plates. On the other hand, the screw drives the lifting plate to move up, so that the lifting plate no longer hinders the airflow from the top of the front row of antibacterial filter cotton plates to the rear row of antibacterial filter cotton plates, thereby expanding the airflow area and avoiding the thickness of the front row of antibacterial filter cotton plates hindering the airflow speed. In this way, multiple rows of antibacterial filter cotton plates can be rotated to perform filtering work under the premise of ensuring the airflow speed. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0036] See also Figure 1 , a purification device for air conditioning ventilation ducts for edible fungus cultivation, comprising a housing 2, a lifting plate 4, an antibacterial filter cotton plate 5 and a screw 6;

[0037] Specific visible Figure 1 , Figure 2 and Figure 3 , three inner mounting frames 1 arranged front and back are movably passed through the shell 2 horizontally, and the inner mounting frames 1 are fixed in the shell 2 by screws after being inserted into the shell 2. A row of connecting rods 7 are rotated through the upper end of each inner mounting frame 1, and the lower end of the connecting rod 7 is fixed to the upper end rotation center of the antibacterial filter cotton plate 5, so that the antibacterial filter cotton plate 5 is rotated in the inner mounting frame 1 through the connecting rod 7;

[0038] The three-row antibacterial filter cotton plate 5 arrangement method is shown in Figure 6 ,from Figure 6 It can be seen that the middle row of antibacterial filter cotton plates 5 are misaligned with the front and rear rows of antibacterial filter cotton plates 5 in the horizontal plane. The specific misalignment is that any antibacterial filter cotton plate 5 in the middle is located directly behind the middle of the two adjacent antibacterial filter cotton plates 5 in the front row, and any antibacterial filter cotton plate 5 in the middle is located directly in front of the middle of the two adjacent antibacterial filter cotton plates 5 in the rear row;

[0039] In order to improve the sterilization and purification capabilities, please refer to Figure 6 There are four sterilization lamps 8 in a linear array at both lateral ends of the housing 2, and the left end of the inner mounting frame 1 is located between two adjacent sterilization lamps 8 in the left row of sterilization lamps 8, and the right end of the inner mounting frame 1 is located between two adjacent sterilization lamps 8 in the right row of sterilization lamps 8, so that the end of a row of antibacterial filter cotton plates 5 is located between two adjacent sterilization lamps 8;

[0040] The center of the upper end of the connecting rod 7 is convex upward, and a groove is provided at the lower end of the screw rod 6, so that the convex part of the upper end of the connecting rod 7 moves upward and penetrates into the groove at the lower end of the screw rod 6. For specific connection methods, see Figure 3 and Figure 8 When the screw 6 rotates, it drives the connecting rod 7 to rotate, so that the antibacterial filter cotton plate 5 and the screw 6 are fixed together through the connecting rod 7. The power component 3 is installed on the upper end of the housing 2, and the upper end of the screw 6 is fixed to the output end of the power component 3. The power component 3 drives the screw 6 to rotate;

[0041] Lifting plate 4: See Figure 5 and Figure 8 The lifting plate 4 is movable up and down and inserted in the upper end of the outer shell 2. The screw 6 threadedly passes through the lifting plate 4 to drive the lifting plate 4 to move up and down. The number of lifting plates 4 is equal to the number of rows of antibacterial filter cotton plates 5 and is arranged in a linear array in the outer shell 2. Each lifting plate 4 is located above a row of antibacterial filter cotton plates 5. When the lifting plate 4 moves down, the lifting plate 4 is located between the lower side of the upper end of the outer shell 2 and the upper end of the inner mounting frame 1, preventing the airflow from flowing from the top of the inner mounting frame 1. When the lifting plate 4 moves up, the lifting plate 4 moves into the upper end of the outer shell 2. At this time, the space above the inner mounting frame 1 is unobstructed, and the airflow flows smoothly to the rear row of antibacterial filter cotton plates 5.

[0042] In this embodiment, the power assembly 3 includes a motor 31, a transmission wheel 32, a transmission belt 33 and a pressure wheel 34. Figure 1 and Figure 2 The motor 31 is fixed on the side of the housing 2, and the output end of the motor 31 and the upper end of the screw 6 are fixed with a transmission wheel 32. A transmission belt 33 is sleeved between a row of transmission wheels 32 and is connected through the transmission belt 33. The pressing wheels 34 rotate in groups on the upper side of the housing 2, and two are in a group. Each group of pressing wheels 34 is located between two adjacent transmission wheels 32 in the same row, and two opposite sides of the transmission belt 33 are sandwiched between the two pressing wheels 34 in each group.

[0043] In addition, the transmission wheel 32 and the transmission belt 33 can also be replaced by transmission gears and toothed belts.

[0044] Working principle:

[0045] When in use, the shell 2 is fixed in the ventilation duct by screws, and the three motors 31 and the sterilization lamp 8 are connected to the external control center. The sterilization lamp 8 is in a normally open state to be powered on for sterilization. The three motors 31 are powered on in rotation for equal periods of time. When a row of antibacterial filter cotton plates 5 work for 1 day or other periods of time, the motor 31 drives the transmission wheel 32 to rotate when it is powered on, and the transmission wheel 32 drives all other transmission wheels 32 to rotate through the transmission belt 33, and the rotating wheel 32 drives the screw 6 to rotate. On the one hand, the screw 6 drives the connecting rod 7 to rotate, and the connecting rod 7 drives the antibacterial filter cotton plate 5 to rotate. On the other hand, the screw 6 drives the lifting plate 4 to move upward until the lifting plate 4 moves to the upper end of the shell 2. At this time, the antibacterial filter cotton plates 5 are placed front and back, and a part of the airflow flows from the middle of the two adjacent antibacterial filter cotton plates 5 to the rear antibacterial filter cotton plate 5, and the other part of the airflow flows from the space above the inner mounting frame 1 to the rear antibacterial filter cotton plate 5, so that the rear antibacterial filter cotton plate 5 performs filtering and purification work;

[0046] After all the antibacterial filter cotton plates 5 have been working for a period of time, the screws between the inner mounting frame 1 and the outer shell 2 can be removed to pull the inner mounting frame 1 out of the outer shell 2, and the connecting rod 7 is disengaged from the screw rod 6, so that the inner mounting frame 1 and the antibacterial filter cotton plates 5 can be completely pulled out for cleaning, maintenance or replacement.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
