Description

A device for desanding and discharging food waste slurry

technical field

The utility model relates to a kitchen garbage treatment technology, in particular to a kitchen garbage slurry desanding liquid discharge device.

Background technique

People produce all kinds of waste and garbage in urban life from time to time. Among them, kitchen waste refers to the waste left over from the kitchen processing ingredients, and fruit and vegetable waste mainly refers to all kinds of discarded fruits and vegetables produced in the fruit and vegetable market. Garbage, both types of garbage have the characteristics of mainly organic matter. Since the domestic waste treatment technology is still at a relatively low-level development stage, the existing kitchen waste fruit and vegetable waste is generally not classified, and is transported to the landfill together with ordinary waste. Such treatment will cause great environmental pollution, not only generate The leachate will pollute the groundwater, and the methane and strong smell will seriously affect people's life and health. But in fact, the vast majority of kitchen waste, fruit and vegetable waste are organic matter and heat sources. It can be considered to recover bioenergy after pulping for reuse, reducing people's demand and consumption of nature, which will be of great significance to the protection of human living environment.

The applicant once designed an integrated food waste removal and pulping machine and applied for the patent No. ZL201220040082.9 and subsequent series of partially improved patents. The structure of the food waste removal and pulping integrated machine includes a shell 1. The rotating shaft in the housing and the motor on one side of the housing, the rotating shaft is driven by the motor, and the upper part of the housing is provided with a material inlet and a sundries outlet, which are respectively located at There are several crushing arms on the rotating shaft near the two ends of the shell, and the crushing arms are distributed on the rotating shaft in a spiral shape, and one end of the crushing arm is hinged to the rotating shaft, and can be rotated on a plane perpendicular to the axis of the rotating shaft. Rotate upward; the bottom of the housing is a screen structure, and a liquid collecting bucket is arranged below the housing. The liquid collecting bucket is conical and the lower port is a liquid outlet; the screen structure is located at the The inner side of the opening at the upper end of the bucket.

The above-mentioned equipment can be used for pulping treatment of kitchen waste, and the prepared slurry is rich in biomass and heat source, and can be recycled after biochemical treatment. However, the pulping machine needs to recycle kitchen waste for treatment, so the installation position on the ground is generally low during implementation, and the treated slurry is usually transported to the waste water treatment workshop by vehicles. Therefore, the slurry flowing out of the liquid outlet of the pulping machine needs to be collected and then lifted to the transport vehicle by a pump. However, the food waste has the characteristics of very high viscosity and some glass ceramic slag, which can easily lead to damage to the pump and a high failure rate of the pump.

In order to solve the above problems, the applicant also designed a kitchen waste removal and pulping integrated machine slurry delivery equipment and applied for a utility model patent with the patent number ZL201420242600.4. The slurry delivery equipment includes a liquid storage shell , the inlet end on one side of the liquid storage shell is connected to the liquid outlet of the food waste removal and pulping machine, and the other side of the liquid storage shell is connected to an inclined lifting cylinder for liquid discharge, and the upper part of the inclined lifting cylinder is A downward liquid outlet cylinder is arranged on the lower side near the end position, and the middle part of the oblique lifting cylinder is fixedly supported on a support frame installed on the ground. The bottom of the liquid storage shell is provided with a V-shaped grit chamber, and the sand is discharged by the switch valve. In this way, the equipment can quickly and efficiently complete the transportation of garbage slurry from the equipment outlet to the transport vehicle, and has the advantages of improving the comfort of slurry transportation and improving the transportation efficiency.

However, this kind of food waste removal and pulping integrated machine slurry conveying equipment still has the following defects: first, the sand settling mechanism used for sand discharge in the equipment cannot discharge sand in real time, because there are many solid sand particles in the kitchen waste slurry. When there is too much grit in the grit chamber and cannot be removed in time, the grit will enter the inclined lifting cylinder with the slurry and be discharged, making it difficult to remove the grit in the slurry. Secondly, the fluid-like slurry is lifted and output by the inclined lifting cylinder, and the output efficiency of the slurry is low. In order to improve the efficiency, it is necessary to reduce the gap between the blades in the lifting cylinder and the cylinder wall, which is easy to cause jamming due to incomplete removal of sand particles. blocked and damaged. Therefore, the existing food waste removal and pulping integrated machine slurry conveying equipment has poor sand and liquid output efficiency and smoothness, is easy to be blocked and damaged, and has a high failure rate.
