Treatment device for producing matrixes and organic manures by utilizing dairy cow excrements

Abstract

The invention relates to a treatment device of human or animal excrements, in particular to a treatment device for producing matrixes and organic manures by utilizing dairy cow excrements. The treatment device comprises a cow excrement tank, an I-level separation device, an II-level separation device and a fermentation tank, wherein the cow excrement tank is connected with the I-level separation device through a pipeline; an underflow pump is arranged between the cow excrement tank and the I-level separation device; the I-level separation device is connected with the fermentation tank througha pipeline; the bottom of the I-level separation device is provided with a liquid-phase collection groove; the liquid-phase collection groove is connected with the underflow pump; a mixing tank is connected to the outlet end of the underflow pump; the upper part of the mixing tank is provided with a flocculant storage tank; and the mixing tank is connected with the II-level separation device through a pipeline. The treatment device can be used for efficiently treating the cow excrements by replacing natural drying with mechanization and separating the cow excrements into the matrixes and the organic manures, thereby enhancing the utilization ratio of the cow excrements.

Description

technical field [0001] The invention relates to a treatment device for human or animal excrement, in particular to a treatment device for producing matrix and organic manure using cow manure. Background technique [0002] At present, there are three main ways to deal with cow manure: directly use it as fertilizer for crops and flowers, dry it in the sun, or directly wash it into ponds, ditches or rivers with water. Existing cow dung natural drying treatment method such as figure 1 shown. According to estimates, a dairy cow produces an average of 30-50 kg of cow dung per day, and a cow farm with a scale of 1,000 cows produces 30-50 tons of cow dung per day. , it is difficult to process all of them, and the direct use of untreated cow dung as fertilizer has many disadvantages: one is that it is easy to burn seedlings if it is used improperly without fermentation; the other is that the transportation cost is too high because the water content of fresh cow dung is high, Gener...

According to estimates, a dairy cow produces an average of 30-50 kg of cow dung per day, and a cow farm with a scale of 1,000 cows produces 30-50 tons of cow dung per day. , it is difficult to process all of them, and the direct use of untreated cow dung as fertilizer has many disadvantages: one is that it is easy to burn seedlings if it is used improperly without fermentation; the other is that the transportation cost is too high because the water content of fresh cow dung is high, Generally, it is about 85%; third, dripping during transportation can easily cause secondary pollution along the way

However, there is currently no complete set of devices that can efficiently process cow dung in dairy farms. For example, the Chinese utility model patent ZL200820161484.8 provides a solid-liquid separator for feces. The solid-liquid separator is a spiral separation mechanism. However, if only a simple solid-liquid separation treatment is performed on the cow dung, the processed cow dung is not suitable for secondary use as fertilizer due to its mixed components.

Such a large amount of cow dung is wasted, so there is an urgent need for a dairy farm cow dung treatment device with a large processing capacity and by-products that can be used as products for secondary use.
