Description

Technical Field

[0002] With the improvement of the economic and living standards, various kinds of garbage generated in daily life are increasing. Among them, kitchen waste is a major category of domestic waste. At present, one of the treatment methods for kitchen waste is to first perform sorting to remove large materials, and the remaining materials enter the pulping machine for pulping. The materials enter the crushing chamber of the pulping machine from the feeding port, and are conveyed towards the discharging port while being crushed under the action of the spiral swing hammers. The crushed organic substances pass through the screen and fall into the discharging trough at the bottom. The light substances such as fibers and plastics that are not crushed are conveyed to the discharging port under the action of the spiral swing hammers and discharged from the discharging port. This treatment method requires removing large materials first, wasting manpower and material resources, with high labor intensity, low efficiency, and high cost. Only by knocking and crushing the materials with the swing hammers, there is no setting of blades to slap the materials at high speed, resulting in high moisture content of the discharged slag and a large amount of sticky organic matter. Moreover, in actual use, kitchen waste often contains sundries such as ceramics, metals, and plastics. If these sundries cannot be separated, they may be broken and mixed into the organic matter slurry, affecting the subsequent utilization of the organic matter slurry, or not being crushed but always mixed in the garbage, affecting the normal crushing of the organic matter.

DETAILED DESCRIPTION

[0020] 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 in 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.

[0021] like Figures 1 to 4 As shown, the present embodiment provides a garbage treatment device, the device comprises a frame, a treatment bin 1 arranged on the frame, a feed port 2 is arranged at the upper part of the treatment bin 1, a main shaft 3 is rotatably arranged in the treatment bin 1 and horizontally penetrates the treatment bin 1, a propulsion mechanism 4 for feeding is arranged at the front end of the main shaft 3, a separation and crushing mechanism 5 for separating, conveying and crushing materials and a scattering mechanism 6 for scattering materials are arranged behind the propulsion mechanism 4, the scattering mechanism 6 is arranged at the rear end of the separation and crushing mechanism 5, a screen assembly 7 is arranged at the bottom of the separation and crushing mechanism 5, a pulp outlet 8 is arranged on the screen assembly 7, and a slag outlet 9 is arranged at the bottom of the scattering mechanism 6. In the present embodiment, the feed port 2 is arranged at the upper part of the propulsion mechanism 4, a feed hopper can be arranged at the feed port 2 to facilitate feeding, a water inlet can be arranged next to the feed port 2 to slurry the material, the main shaft 3 is driven by a driving motor, and the main shaft 3 and the motor are connected by a transmission assembly, for example, by a synchronous wheel and a synchronous belt.

[0022] The propulsion mechanism 4 includes a spiral blade 41 spirally wound around the main shaft 4. As the main shaft 3 rotates, the spiral blade 41 rotates to transport the material to the separation and crushing mechanism 5, so that the material is fed faster.

[0023] The separation and crushing mechanism 5 includes centrifugal blades 51 spaced on the main shaft 3 for centrifugally separating and conveying materials, a rotating shaft 52 arranged circumferentially on the main shaft 3, and hammer blades 53 spaced on the rotating shaft 52 for crushing materials. The hammer blades 53 are arranged between the centrifugal blades 51. The centrifugal blades 51 extend radially around the main shaft 3 and are arranged at equal intervals axially. In this embodiment, the centrifugal blades 51 include multiple groups of centrifugal blade arrays. For easy understanding, the first group of centrifugal blade arrays is denoted as 511, and the second group of centrifugal blade arrays is denoted as 512. The number of centrifugal blades in each group of centrifugal blade arrays is the same, with 2 blades. The adjacent two groups of centrifugal blade arrays distributed axially along the main shaft 3 are staggered. In this way, the centrifugal blades 51 achieve high-speed flapping under the drive of the main shaft 3. At the same time, due to the entry of subsequent kitchen waste, large pieces of materials or hard objects such as metals, plastics, and ceramics in the waste are continuously pushed forward to the dispersing mechanism 6 for dispersion and separated from other materials. The hammer blades 53 include multiple groups. Each group of hammer blades 53 is arranged on the same rotating shaft 52, and multiple groups of hammer blades 53 are staggered. For example, 6 rotating shafts 52 can be set and 6 groups of hammer blades 53 can be installed. Mounting brackets 54 for installing the rotating shafts 52 can be spaced on the main shaft 3. The hammer blades 53 include two blades, and there are different spacings between the two hammer blades 53. In this way, the rotation of the main shaft 3 drives the rotation of the rotating shaft 52, and the rotation of the rotating shaft 52 drives the rotation of the hammer blades 53 to crush the materials and grind them into a pulp. The screen assembly 7 is a semi-surrounding structure with a width gradually decreasing from top to bottom. The width above the screen assembly 7 is greater than or slightly greater than the diameter of the main shaft 3 after installing the separation and crushing mechanism 5, so that it can surround the main shaft 3. The crushed materials (pulp) fall into the screen assembly 7 and flow out of the pulp outlet 8 through the screen assembly 7. The screen assembly 7 includes a screen frame 71 and a screen 72 installed on the screen frame 71. Through holes 711 are opened on the screen frame 71. The mesh number of the screen 72 is smaller than the mesh number of the through holes 711. The screen frame 71 plays a role in supporting and protecting the screen 72 and improves the service life of the screen 72.

[0024] The dispersing mechanism includes dispersing blades 61. The dispersing blades 61 extend radially around the main shaft 3 and are arranged at equal intervals axially, including multiple groups of dispersing blade arrays. In this embodiment, two groups of dispersing blade arrays are set. The first group of dispersing blade arrays is denoted as 611, and the second group of dispersing blade arrays is denoted as 612. The number of dispersing blades in each group of dispersing blade arrays is the same. The adjacent two groups of dispersing blade arrays distributed axially along the main shaft 3 are staggered. In this way, when large pieces of materials or hard objects such as metals, plastics, and ceramics in the waste reach the dispersing mechanism 6, the dispersing blades 61 achieve high-speed flapping under the drive of the main shaft 3 to break the large pieces of materials and remove the slag from the slag outlet 9.

[0025] When the utility model is used for garbage treatment, garbage enters from the feeding hopper, and the driving motor drives the main shaft 3 to rotate. As the main shaft 3 rotates, the spiral blade 41 is driven to rotate, and the materials are conveyed to the separation and crushing mechanism 5. Water enters the treatment chamber 1 from the water inlet, and the centrifugal blade 51 realizes high-speed flapping under the drive of the main shaft 3. At the same time, due to the subsequent entry of kitchen waste, large materials or hard objects such as metals, plastics, and ceramics in the garbage are continuously pushed forward to the dispersing mechanism 6 for dispersion and separated from other materials. The hammer-type blade 53 rotates to crush the materials into pulp. The crushed materials (pulp) fall into the screen assembly 7 and flow out of the pulp outlet 8 through the screen assembly 7 for the next process treatment. The dispersing blade 61 realizes high-speed flapping under the drive of the main shaft 3 to break the large materials, and the slag is removed from the slag outlet 9 for the next process treatment. It simultaneously has the functions of spiral feeding, high-speed centrifugation, hammer crusher, and centrifugal feeding.

[0026] In the utility model, a separation and crushing mechanism and a dispersing mechanism are arranged on the main shaft, and a pulp outlet and a slag outlet are respectively arranged below the separation and crushing mechanism and the dispersing mechanism. Through the rotation and propulsion of the main shaft, large materials or hard objects such as metals, plastics, and ceramics in the garbage are continuously pushed forward to the dispersing mechanism for dispersion and separated from other materials, without affecting the crushing of other materials. Other materials are crushed into pulp, and various organic matters in the materials are completely crushed, so that the crushing of solid materials is more thorough, ensuring the full recycling of organic matters, improving the efficiency and utilization rate of garbage treatment, and realizing the automatic operation of the garbage treatment process.

[0027] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
