Description

TECHNICAL FIELD

[0001] The present application relates to the field of garbage treatment, in particular to a vertical pulper for perishable garbage. BACKGROUND

[0002] With the improvement of China's economy and people's living standards year by year, people's food consumption ability is also increasing, but at the same time, a large amount of kitchen garbage is also produced, and if these garbage is not properly treated, it will bring a lot of hidden troubles to the surrounding environment and health conditions. Kitchen garbage has the characteristics of rich organic matter content, high water content and easy to rot, and is also mixed with some plastic products, which brings difficulties to the treatment of kitchen garbage. In the treatment process of kitchen garbage, the general steps are to first remove impurities and crush, then make pulp, then three-phase separation, and finally anaerobic fermentation. The pulper is the core equipment in the pulping process, and in the pulping process, the organic matter is made into slurry, and at the same time, a lot of impurities are crushed.

[0003] The traditional pulper has a vertical crushing cylinder cavity with a mesh, and a spiral blade shaft is installed in the crushing cylinder cavity. When running, the kitchen / garbage is transported into the crushing cylinder cavity, and the kitchen / garbage with less fiber and easy to cut off is cut into pulp by the high-speed rotating spiral blade shaft, and then flows out of the crushing cylinder cavity through the mesh on the cylinder cavity. However, perishable garbage (especially kitchen garbage) often contains a large amount of plant fiber, and after working for a certain period of time, the fiber residue will seriously block the crushing cylinder cavity and the equipment will run overload. In order to improve efficiency and avoid burning the driving motor, the machine must be stopped and the fiber residue in the crushing cylinder cavity must be manually removed before the machine can continue to work. In addition, the cutter is usually arranged in the middle of the crushing cylinder cavity, and when it is running at high speed, it is easy to be damaged by hard solids (such as glass, stone, etc.), which reduces the service life of the cutter. SUMMARY

[0004] The present application aims to overcome the shortcomings of the prior art and provide a vertical pulper for perishable garbage, which solves the problems of easy blockage and short service life of the cutter of the existing pulper.

[0005] The purpose of the present application is achieved by the following technical scheme: the vertical pulper for perishable garbage comprises a vertical pulper body, a feed inlet is formed at the top of the vertical pulper body for feeding perishable garbage, a top cover is installed on the feed inlet, a driving motor is arranged below the vertical pulper body, a motor shaft of the driving motor penetrates into the inner cavity of the vertical pulper body, and is used to connect a cutter arranged at the bottom of the inner cavity of the vertical pulper body, a guide plate is fixed on the inner wall of the vertical pulper body, and is used to stratify the perishable garbage; a discharge outlet is formed on the inner wall of the vertical pulper body for discharging slurry, and a residue discharge port is formed at the bottom of the inner cavity of the vertical pulper body for discharging heavy residue.

[0023] The present invention will now be described in detail with reference to the accompanying drawings:

[0024] Example: As attached Figures 1-4 As shown, this vertical pulping machine for perishable waste includes a vertical pulping machine body 1, a top cover 101, a feed inlet 102, a discharge outlet 103, a slag discharge outlet 104, a guide plate 105, a support leg 106, a guide slope 107, a rotary cutter 201, a drive motor 202, a perforated screen plate 203, a vortex 204, a motor base 3, and a flexible pad 4.

[0025] Reference Appendix Figure 1 , 2 A feed inlet 102 is provided at the top of the vertical pulper body 1, through which perishable waste is fed into the inner cavity of the vertical pulper body 1. Preferably, the size of the feed inlet 102 is the same as the outer diameter of the vertical pulper body 1, which can improve the feeding efficiency. A top cover 101 is installed on the feed inlet 102 to ensure the system operates in a closed manner, resulting in low odor generation and minimal environmental impact. A drive motor 202 is located below the vertical pulper body 1. The drive motor 202 is plugged into the motor base 3, and a flexible pad 4 is placed between the motor base 3 and the drive motor 202 to effectively reduce vibration and noise during equipment operation. The motor shaft of the drive motor 202 passes through the inner cavity of the vertical pulper body 1 to connect and drive the rotating cutter 201 (e.g., Figure 4 As shown, the rotary cutter 201 is located at the bottom of the inner cavity of the vertical pulper body 1, with its upper end facing the inner cavity of the vertical pulper body 1. A slag discharge port 104 is opened at the bottom of the inner cavity of the vertical pulper body 1 to discharge heavy slag with larger particle size (such as glass and gravel). Support legs 106 are welded and fixed to the bottom of the vertical pulper body 1 for support.

[0026] like Figure 1 As shown, a guide plate 105 is fixed on the inner wall of the vertical pulper body 1. The guide plate 105 has a pyramidal structure and a guide slope 107 inclined towards the slag discharge port 104. When the rotary cutter 201 rotates, under the action of centrifugal force, hard heavy slag (such as glass and gravel) gradually moves towards the cavity wall of the vertical pulper body 1. After encountering the guide plate 105 (guide slope 107), it gathers towards the bottom of the cavity, so that the perishable waste is layered.

[0027] Reference to the accompanying drawings Figure 2 , when the rotating knife 201 rotates in the perishable garbage to form a vortex 204, the differential speed of the hydraulic vortex flow layer is used to make the components in the perishable garbage be subjected to tearing, rubbing and friction, so that the light weight residue (such as plastic and paper) is broken, and the particle diameter of the organic matter component (including fibrous material) is significantly reduced. A discharge port 103 is arranged on the inner wall of the vertical pulper main body 1, which is used to discharge the produced organic slurry after being broken. The height position of the discharge port 103 is higher than that of the residue discharge port 104, so as to avoid the heavy residue from being discharged from the discharge port 103 and blocking the discharge port 103.

[0028] As Figure 1 , 3 shown, a porous sieve plate 203 is arranged between the lower end surface of the rotating knife 201 and the residue discharge port 104, and the porous sieve plate 203 is fixed at the bottom of the vertical pulper main body 1, which can be used for filtering the heavy residue. The heavy residue with large particle diameter cannot be directly discharged, and needs to be further broken before being discharged from the residue discharge port 104 through the porous sieve plate 203. The setting of the porous sieve plate 203 can protect the bottom of the cavity and reduce the impact of the hard heavy residue, and facilitate cleaning. The organic slurry and the hard heavy residue are discharged through the discharge port 103 and the residue discharge port 104 respectively, and various components are efficiently separated.

[0029] The working process of the present application: when working, the top cover 101 is opened to put the perishable garbage into the inner cavity of the vertical pulper main body 1. During the operation of the equipment, the top cover 101 is closed to reduce noise and odor dispersion. Then, the driving motor 202 is started to drive the rotating knife 201 to rotate synchronously. When the rotating knife 201 rotates in the perishable garbage, a vortex 204 is formed. The differential speed of the hydraulic vortex flow layer is used to make the components in the perishable garbage be subjected to tearing, rubbing and friction, so that the light weight residue (such as plastic and paper) is broken, and the particle diameter of the organic matter component (including fibrous material) is significantly reduced. At the same time, under the action of centrifugal force, the hard heavy residue (such as glass and gravel) gradually moves to the cavity wall of the vertical pulper main body 1, and is collected to the bottom of the cavity after meeting the flow guide plate 105 (flow guide slope 107), so that the perishable garbage is layered. The generated organic slurry is discharged from the discharge port 103, and the hard solid (such as glass, stone, etc.) mixed in the perishable garbage is generated as hard heavy residue after completing a pulping cycle, and is settled at the bottom of the cavity. After being filtered by the porous sieve plate 203, it is discharged in time through the residue discharge port 104, and various components are efficiently separated.

[0030] The perishable garbage vertical pulper has reasonable structure design and is convenient to use; according to the water power vortex principle, the perishable garbage is simultaneously realized in the aspects of bag breaking, organic matter pulping and impurity separation; has the characteristics of low organic matter loss rate, high resource rate, short process flow, small land occupation, strong system stability, safe operation, low equipment failure rate and the like. Meanwhile, the system is operated in a closed mode, has small odor production and small environmental influence.

[0031] It can be understood that equivalent replacement or change of the technical solutions and inventive concepts of the present application by those skilled in the art shall belong to the protection scope of the claims of the present application.
