[0002] With the rapid economic development and accelerated industrialization, the output of hazardous waste is increasing. Therefore, it is necessary to crush and pretreat waste with solid hazardous structures before collection. This is usually done by crushing and pretreating with a pretreatment device, and the existing pretreatment devices are used for crushing and pretreating hazardous waste before collection.

[0003] Existing pretreatment devices for hazardous waste collection and pretreatment directly feed waste into the treatment tank through the inlet, leaving the top or inlet of the tank exposed to the outside. This makes it inconvenient for material feeding and protection. Furthermore, excessive material accumulation during feeding reduces the crushing effect, and the crushing force can cause internal waste to fly out, even directly escaping and posing a danger. This reduces the operational risk of the pretreatment device and affects the convenience of material feeding and protection during the crushing process of hazardous waste collection. Therefore, this utility model proposes a safer hazardous waste collection and pretreatment device. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a safe hazardous waste collection and pretreatment device, including a pretreatment box 101, a feed box 102 welded and fixed to the upper surface of the pretreatment box 101, a discharge port 104 provided on one side of the bottom of the pretreatment box 101, and two crushing rollers 105 installed at the top of the inside of the pretreatment box 101 through bearings.

[0025] Gears 106 are fixed inside the pretreatment box 101 on the end surface of the crushing roller 105, and the two gears 106 mesh with each other. A reduction motor 107 is fixed on the rear surface of the pretreatment box 101 at the end of the crushing roller 105. A controller 103 is fixed on the front surface of the pretreatment box 101. The controller 103 is electrically connected to the reduction motor 107 through wires. A material guiding and protection mechanism is provided inside the feed box 102.

[0026] The material guiding and protection mechanism includes material blocking and protection components installed on both sides inside the feed box 102. The surface of the material blocking and protection components is provided with material guiding component one, and the bottom of the feed box 102 is provided with material guiding component two. When the material is fed into the feed box 102, the material guiding and protection mechanism can guide the waste to fall evenly and effectively protect it from flying and jumping during the crushing process, making it less likely to fly into the outside world and cause danger, thus ensuring the safe crushing and treatment of waste.

[0027] To facilitate material feeding and protection using the material blocking assembly, and to prevent internal fragments from flying out and causing danger during crushing, in this embodiment, preferably, the material blocking and protection assembly is welded and fixed to the material feeding protection plates 1021 on both sides inside the feed box 102. A reinforcing support plate 1023 is welded between the lower surface of the material feeding protection plate 1021 and the side of the feed box 102. After the reinforcing support plate 1023 reinforces the material feeding protection plate 1021, the waste is fed into the feed box through the material feeding protection plate 1021. When the waste flies out during crushing, the material feeding protection plate 1021 protects it from flying out and ensures safe crushing.

[0028] In order to facilitate the uniform falling of material through the feeding grooves 1022 when protected by the feeding guard plate 1021, in this embodiment, preferably, the feeding component one includes feeding grooves 1022 formed at equal intervals on the surface of the feeding guard plate 1021, and the protruding part between the two feeding grooves 1022 on the surface of the feeding guard plate 1021 has an arc-shaped structure, so that the material can be uniformly drawn down into the feed box 102 by the feeding grooves 1022 when the feeding guard plate 1021 is protecting the material, and the feeding guard plate 1021 protects the material from flying to the outside during crushing.

[0029] To facilitate the uniform falling of waste entering the bottom of the feed box 102 onto the surfaces of the two crushing rollers 105 via the feeding assembly 2, thus enabling crushing processing, in this embodiment, preferably, the feeding assembly 2 includes two left feeding plates 1024 welded and fixed to one side of the bottom inside the feed box 102, two right feeding plates 1026 welded to the other side of the bottom inside the feed box 102, and a vertical plate 1025 welded to the middle position of the bottom inside the feed box 102. The waste is fed to one end of the upper surface of the crushing roller 105 through the left feeding plates 1024, and falls vertically onto the surface of the crushing roller 105 through the vertical falling opening separated by the vertical plate 1025. The right feeding plates 1026 feed the waste into the other end of the surface of the crushing roller 105, facilitating uniform feeding between the two crushing rollers 105.

[0030] A material blocking and cleaning mechanism is provided on one side of the upper surface of the crushing roller 105. The material blocking and cleaning mechanism includes a fixed mounting component that is fixedly installed at the top of the pretreatment box 101. The material blocking and cleaning component is provided between the inside of the fixed mounting component and the surface of the crushing roller 105. When pretreatment waste enters between the two crushing rollers 105, the material blocking and cleaning mechanism can block and clean the side of the crushing roller 105, effectively preventing uncrushed waste from entering and waste from adhering to the surface of the crushing roller 105.

[0031] To facilitate the installation of the mounting plate 1052 and the cleaning brush 1053 using a fixed mounting assembly, in this embodiment, preferably, the fixed mounting assembly includes mounting inclined plates 1051 welded and fixed to both sides of the top of the pretreatment box 101. The mounting inclined plates 1051 have a limiting groove 1054 inside, which allows the mounting plate 1052 and the cleaning brush 1053 to be elastically and tightly pressed and installed inside the limiting groove 1054, facilitating installation and use.

[0032] To facilitate material blocking and prevent side entry via the material blocking and cleaning assembly, and to facilitate surface cleaning of the crushing roller 105, in this embodiment, preferably, the material blocking and cleaning assembly includes a mounting plate 1052 that is positioned inside the limiting groove 1054. A cleaning brush 1053 is provided at the bottom end of the mounting plate 1052 and contacts the surface of the crushing roller 105. A compression spring 1055 is welded equidistantly between the top end of the mounting plate 1052 and the inner top end of the limiting groove 1054. The mounting plate 1052, the cleaning brush 1053, and the mounting inclined plate 1051 can form a material blocking surface to block material, preventing waste from directly entering from the side and thus preventing it from being crushed. At the same time as blocking the material, the compression spring 1055 elastically presses the mounting plate 1052 and the cleaning brush 1053 onto the surface of the crushing roller 105, facilitating cleaning.

[0033] In this utility model, the cleaning brush 1053 is made of a very easy-to-clean wire material, and the friction between the cleaning brush 1053 and the surface of the crushing roller 105 during cleaning is extremely small. The crushing roller 105 has high hardness, so the extremely small friction generated at this time is negligible.

[0034] The working principle and usage process of this utility model are as follows: When using this safe hazardous waste collection and pretreatment device, the pretreatment box 101 is first placed stably in its designated position with its bottom end in contact with the ground. When hazardous waste enters the pretreatment box 101 through the feeding box 102, it is guided down through the feeding groove 1022 on the surface of the feeding guard plate 1021 and then through the feeding guard plate 1021 on the other side, re-entering the bottom of the feeding box 102. After evenly falling, it is again guided down through the left feeding plate 1024. Waste is fed to one end of the upper surface of the crushing roller 105 and falls vertically onto the surface of the crushing roller 105 through a vertical drop opening isolated by the vertical plate 1025. The right feed plate 1026 feeds the material into the other end of the surface of the crushing roller 105, facilitating uniform feeding. After feeding, when the crushing process is carried out by the two crushing rollers 105 rotating in opposite directions and some fragments fly off, they are directly protected by the two feed protection plates 1021, effectively preventing them from flying off to the outside, ensuring safe operation, and improving the convenience and safety of feed protection in the pretreatment device when collecting and crushing hazardous waste.

[0035] Then the waste is evenly dropped between the two crushing rollers 105. The reduction motor 107 drives the gear 106 to rotate. The two gears 106 mesh to drive the two crushing rollers 105 to rotate in opposite directions, so that the hazardous waste can be crushed by the two crushing rollers 105. After processing, the waste falls into the bottom of the pretreatment box 101 and is introduced into the discharge port 104 through the inclined structure. It is then discharged from the discharge port 104 to the outside for collection and processing.

[0036] Finally, when the crushing roller 105 is rotating and crushing, the deformation of the compression spring 1055 causes the mounting plate 1052 and the cleaning brush 1053 to press tightly against the surface of the crushing roller 105. When feeding, the mounting inclined plate 1051, the mounting plate 1052 and the cleaning brush 1053 form a material blocking structure to prevent the material from falling to the bottom side during feeding, which facilitates material blocking and protection. At the same time as material blocking and protection, the cleaning brush 1053 contacts the surface of the crushing roller 105. When the crushing roller 105 is rolling and crushing, it is cleaned by the cleaning brush 1053 to prevent the surface from being attached to objects and reducing the crushing effect. This improves the convenience of cleaning the material blocking on the upper surface of the crushing roller 105 in the pretreatment device when collecting and crushing hazardous waste.

[0037] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
