Description

Technical Field

[0001] The present invention relates to the technical field of syringe destruction, and in particular to a veterinary syringe destruction device. Background Art

[0002] Veterinary syringes, as a common medical device, are widely used in fields such as disease diagnosis, treatment, and vaccination. However, with the increase in medical activities, the disposal of syringe waste has gradually become an important issue; discarded syringes not only pose a risk of environmental pollution but also may become a means of disease transmission; if syringes are not properly disposed of, they may carry pathogens such as blood, viruses, or bacteria, becoming a source of cross-infection. For example, used needles and syringes discarded randomly may cause injury to others, thereby infecting blood-borne diseases.

[0003] Traditional waste syringes usually need to be treated by methods such as incineration or high-temperature and high-pressure sterilization. These treatment methods may lead to energy consumption and environmental pollution, especially in areas with scarce medical resources; existing treatment devices directly melt the needles and syringes, and finally collect the iron tips. This method requires burning plastics, causing a large amount of black smoke and environmental pollution, and is not conducive to recycling. Therefore, we propose a new type of destruction device that can avoid burning, which can reduce environmental pollution and enable recycling. Summary of the Invention

[0004] In view of the technical problem that the incineration and destruction method in the prior art pollutes the environment and the destruction is not thorough, the present invention adopts the following technical solutions:

It is characterized in that side plug plates one and two, which are symmetrically arranged and have a disc-shaped structure, are respectively arranged at both ends of the baking oven, and annular grooves with a frustum-shaped structure are opened on the opposite sides of side plug plates one and two. Heating coils are fixed at the bottoms of the two annular grooves. Side plug plate one can slide axially for feeding; an anti-needle mechanism extending into the baking oven is arranged between the tops of the two support plates. The anti-needle mechanism includes two vertically arranged channel-shaped slide rails with opposite openings and fixed at the tops of the two support plates. The same support hanger is slidably connected between the two channel-shaped slide rails. A main sprocket and two counter rollers are respectively arranged at the upper and lower ends of the support hanger. The same transmission chain is connected between the main sprocket and the two counter rollers, and a plurality of mutually parallel magnet bars are embedded on the transmission chain.

[0006] Preferably, the inner wall of the annular groove is polished to form heat accumulation, so as to increase the heating effect on the needles with plastic inside.

[0007] Preferably, a feeding notch one is formed above one end of the side baffle one of the baking oven, and a U-shaped notch capable of coinciding with the feeding notch one is formed near the upper part of the flared edge of the side baffle one; a support column extending towards the central position is fixed to the inner circumferential wall of the baking oven below the feeding notch one, and a sliding ring is reserved at the top end of the support column. A guiding push rod is slidably connected to the middle of the sliding ring, and the end of the guiding push rod is fixed to the side surface of the side baffle one; electric heaters adapted to the heating coils on the respective sides are fixed to the sides of the guiding push rod and the side baffle two facing away from each other. During feeding, it is only necessary to retract the side baffle one by a certain distance to expose the feeding position.

The inclined surface of the trapezoidal push block is in close contact with the lower surface of the arc-shaped hinge plate. By providing the trapezoidal push block, the sealing plug can be tightened and loosened by the horizontal movement of the trapezoidal push block itself, with convenient operation, good sealing performance, and good operability.

[0010] Preferably, the lower surface of the trapezoidal push block is higher than the plane where the bottom of the support plate is located to ensure that a device for receiving materials can be placed at the bottom after discharging; threads are formed on the outer circumferential wall of the side baffle two, and threaded grooves adapted to the threads are formed on the inner circumferential wall of one end of the baking oven close to the side baffle two, making the disassembly and assembly of the side baffle two more convenient and facilitating subsequent cleaning.

The center of the arc-shaped plate falls on the rotating shaft. A pull rope is fixed to the top end of the arc-shaped plate, and an electric push rod II is fixed to the bottom end of the pull rope and vertically downward; when it is necessary to control the up-and-down movement of the overall conveyor chain, only the extension rod of the electric push rod II needs to be extended and retracted.

[0013] Preferably, the side of the magnet strip away from the support hanger is flush with the surface of the conveyor chain.

[0016] 1. By setting magnet bars parallel to each other on the conveyor chain, waste products with needle tips can be heated and softened at the beginning. After the iron needle tips fall off, the main sprocket is started to rotate, and the adsorbed needle tips can be slowly taken out for unified collection and treatment. At this time, the separation of the needle tips and plastics can be completed, and there is no need to incinerate the plastics. It only needs to be heated and softened to a molten state, which is convenient for reducing the volume for collection and high-temperature disinfection.

[0017] 2. By setting a vibrator and cooperating with two annular grooves with a frustum-shaped cross-section, all the positions of the remaining needle tips after melting can be arranged in parallel, that is, the direction of the needle tips is parallel to the axis of the baking oven.

[0040] Working principle: When this device is in use, first control the movable side plug plate 15 to retract backward to expose the U-shaped notch and the feeding chute opening 201. Then, put the waste needle tips to be processed into the baking oven 2, and then push the side plug plate 15 back to its original position. Then control the extension rod of the electric push rod 24 to extend to lift the entire support hanger 29, leaving space to melt the needle tips. Then start the two electric heaters 3 until all the needle tips fall off from the needles. After melting for a period of time, start the vibrator 18. Cooperating with the two annular grooves with a frustum-shaped cross-section, all the remaining positions of the melted needle tips can be arranged in parallel to each other, that is, the direction of the needle tips is parallel to the axis of the baking oven 2. At this time, control the entire conveyor chain 7 to descend, and the adsorbed needle tips can be slowly taken out for unified collection and treatment.
