Description

Technical Field

[0001] This utility model relates to the field of indoor air purification technology, specifically an indoor air purification and exhaust device for insecticide preparation. Background Technology

[0002] Pesticides play an important role in agricultural production, as they can kill different pests and thus protect crops. During the pesticide production process, the pesticide preparation plant is filled with volatile pesticide gases. Although production workers wear masks, they still inhale small amounts of toxic gases, which can have a certain impact on their health.

[0003] Chinese patent CN216693905U discloses a novel air purification device for an insecticide manufacturing plant. The device includes a fixed housing, cylindrical in shape and positioned at the top of the manufacturing plant. Several air outlets are arranged along the circumference of the fixed housing at its bottom end, and the fixed housing is connected to the air outlets. The air outlets are arranged along the inner wall of the manufacturing plant, with their axial direction aligned with that of the fixed housing. The top of each air outlet is connected to the fixed housing, and the bottom of the air outlet is sealed. Several air supply pipes are arranged along the height of each air outlet on its side wall, all inclined clockwise or counterclockwise, and all inclined upwards. An air inlet center slot is located at the center of the bottom end of the fixed housing and is connected to a purification component located inside the fixed housing.

[0004] Inside the factory, the air is purified by a purification device inside the base. When the fan on the base surface is working, it draws in air from the outside to drive harmful gases inside the factory into the base. At this time, the outer surface of the fan is easily blocked by the outside air, which requires further cleaning by the staff. Otherwise, it will affect the purification efficiency of the purification device in purifying harmful gases inside the air. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: an indoor air purification and exhaust device for insecticide preparation, including a base 1, four fans 2 are fixedly installed on the upper surface of the base 1, four air supply ducts 3 are fixedly connected to the lower surface of the base 1, all four air supply ducts 3 are connected to the fans 2, and four air outlet pipes 4 are fixedly connected to the surface of each of the four air supply ducts 3. A blocking device 5 is provided on the upper surface of the base 1, and an auxiliary device 6 is provided on the lower surface of the base 1.

[0027] In this embodiment of the utility model: when the purification equipment is working, the fan 2 is started, and the fan 2 introduces external air into the factory. Through the cooperation of the air supply duct 3 and the air outlet duct 4, the harmful gas inside the factory can enter from the position of the auxiliary device 6 in a spiral shape. The purification effect is achieved through the purification components inside the base 1. At this time, the harmful gas particles that are blocked will be blocked and fall to the position of the auxiliary device 6. The air introduced from the outside by the fan 2 will also be blocked by the blocking device 5. The outer surface of the fan 2 will not be connected to impurities that affect the air guiding efficiency.

[0028] like Figure 1-3 As shown, the blocking device 5 includes four mounting plates 501, all of which are fixedly connected to the arc surface of the base 1. A ring 502 is fixedly connected to the surface of each of the four mounting plates 501. A connecting plate 503 is fixedly connected to the surface of the ring 502. A rotating ring 505 is rotatably connected to the surface of the connecting plate 503. A filter cloth 509, made of polyester fiber, is fixedly connected to the inner wall of the rotating ring 505. A circular plate 504 is fixedly connected to the surface of the filter cloth 509. A mounting frame 511 is fixedly connected to the upper surface of the base 1. A motor 512 is fixedly connected to the inner wall of the mounting frame 511. An electric telescopic rod 513 is fixedly connected to the output end of the motor 512. The output end of the electric telescopic rod 513 is fixedly connected to the circular plate 504.

[0029] When outside air comes into contact with the filter cloth 509, impurities in the air are not blocked by the filter cloth 509 and cannot reach the fan 2. Furthermore, the fan 2 can help the indoor airflow in the factory to achieve a good airflow effect, ensuring that the airflow effect can be maintained in a good state for a long time.

[0030] A support telescopic rod 510 is rotatably connected to the lower surface of the circular plate 504, and the end of the support telescopic rod 510 away from the circular plate 504 is rotatably connected to the inner wall of the rotating ring 505.

[0031] When the motor 512 drives the filter cloth 509 to rotate and shake off impurities, the support telescopic rod 510 can be extended with the start of the electric telescopic rod 513. Furthermore, the support of the support telescopic rod 510 can assist the rotating ring 505 to rotate, reducing the damage to the filter cloth 509 during rotation and improving the service life of the filter cloth 509.

[0032] The swivel ring 505 has four rollers 506 rotatably connected to its arc surface, and the arc surfaces of the four rollers 506 are all slidably connected to the upper surface of the connecting plate 503.

[0033] The roller 506 can reduce the friction between the rotating ring 505 and the connecting plate 503, further improving the smoothness of the rotating ring 505 during rotation.

[0034] An external rod 507 is fixedly connected to the arc surface of the connecting plate 503. Several bristles 508 are fixedly connected to the surface of the external rod 507. The several bristles 508 are linearly arrayed on the surface of the external rod 507. The ends of the several bristles 508 away from the external rod 507 are all pressed against the surface of the filter cloth 509.

[0035] When the filter cloth 509 rotates and shakes away impurities, the outer surface of the filter cloth 509 will come into contact with the bristles 508. The bristles 508 can improve the cleaning effect on the surface of the filter cloth 509, thus facilitating the subsequent filtration use of the filter cloth 509.

[0036] Working principle: When the fan 2 is working, the operator can start the electric telescopic rod 513. At this time, the electric telescopic rod 513 will drive the circular plate 504 to move upward, which can cause the filter cloth 509 to unfold in a cone shape. At the same time, the internal support telescopic rod 510 will unfold with the rotation of the circular plate 504, which can provide a simple support effect between the circular plate 504 and the rotating ring 505. After the filter cloth 509 has been blocked for a long time, the operator can start the motor 512. The motor 512 can drive the filter cloth 509 to rotate through the circular plate 504 and the rotating ring 505, which can throw off surface impurities, and the filter cloth 509 can come into contact with the bristles 508, improving the cleaning effect of impurities on the surface of the filter cloth 509.

[0037] like Figure 2 and Figure 4As shown, the auxiliary device 6 includes two telescopic rods 604 connected in series. Both telescopic rods 604 are fixedly connected to the lower surface of the base 1. A slider 601 is fixedly connected to one end of each telescopic rod 604 away from the base 1. Several circular holes 602 are fixedly connected to the surface of the slider 601. A vertical plate 603 is fixedly connected to the side of the slider 601 closest to the base 1. Round rods 605 are fixedly connected to both sides of the vertical plate 603. Semicircular frames 606 are slidably connected to the surface of the round rods 605. The semicircular frames 606 are slidably connected to the surface of the slider 601. A spring 607 is sleeved on the surface of the round rods 605. The two ends of the spring 607 are fixedly connected to the semicircular frames 606 and the vertical plate 603, respectively.

[0038] After a long period of purifying the indoor air of the factory, the staff can remove the slider 601 from the base 1. At this time, with the help of the spring 607, the harmful gas particles collected inside the semi-circular frame 606 can be directly discharged to achieve the cleaning effect. Then, the slider 601 can be attached to the base 1 again to collect harmful gas particles again.

[0039] A folding plate 608 is fixedly connected to the surface of the semi-circular frame 606. The folding plate 608 is in the shape of a "V".

[0040] Due to the special material of the folding plate 608, the folding plate 608 inside the base 1 can guide the falling harmful gas particles, allowing them to fall directly into the semi-circular frame 606, which facilitates the collection by the auxiliary device 6. This prevents the harmful gas particles from escaping from the circular hole 602, making it easier for staff to collect the harmful gas particles.

[0041] A pull rod 609 is slidably connected to the surface of the upright plate 603. The pull rod 609 is slidably connected to the base 1, and one end of the pull rod 609 is fixedly connected to the inner wall of the folding plate 608.

[0042] The pull rod 609 can drive the folding plate 608 to fold and retract, which can help the two semi-circular frames 606 to retract quickly, making it convenient to put the auxiliary device 6 back into the base 1, and can also help the slider 601 to be taken out from the base 1.

[0043] Working principle: When slider 601 is inside base 1, harmful gas enters base 1 through circular hole 602. After being purified inside base 1, the harmful gas particles that are further blocked fall into semi-circular frame 606 for collection. When the purification operation stops, the operator can pull slider 601 through lever 609 to remove slider 601 from base 1. Then, the two semi-circular frames 606 will slide to both sides driven by spring 607 to discharge the collected particles. After the particles are discharged, the operator pushes lever 609 upward. At this time, lever 609 can drive the two semi-circular frames 606 to slide inward simultaneously through folding plate 608, and slider 601 can retract into base 1.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
