Description

Technical Field

[0001] The utility model belongs to the technical field of water-soluble fertilizer production equipment, and in particular relates to a liquid water-soluble fertilizer grinding device. Background Art

[0002] Liquid water-soluble fertilizer is a type of fertilizer that can be dissolved in water. It usually exists in liquid form, which is convenient for storage and transportation. It is widely used in modern agricultural production. During the production process, liquid water-soluble fertilizer requires a colloid mill for sufficient grinding and emulsification. Currently, in order to fully grind the liquid water-soluble fertilizer, it is sometimes necessary to add a feeding pipe to the liquid outlet of the colloid mill. The feeding pipe can pass the liquid water-soluble fertilizer flowing out of the liquid outlet of the colloid mill back into the colloid mill, forming multiple circulation grinding to grind the liquid water-soluble fertilizer more fully. Circulating grinding in this way will result in low grinding efficiency and is not suitable for mass production. Moreover, the current liquid water-soluble fertilizer will be directly passed into the storage tank after being ground by the colloid mill, and there is a lack of screening for some water-soluble fertilizer particles that have not been ground finely, which makes it impossible to guarantee the grinding quality of the liquid water-soluble fertilizer. Summary of the Invention

[0003] The purpose of the utility model is to provide a liquid water-soluble fertilizer grinding device to overcome the problems in the prior art that the liquid water-soluble fertilizer has low grinding efficiency when it is circulated through a colloid mill and is not suitable for mass production, and the quality of the liquid water-soluble fertilizer ground by the current colloid mill cannot be guaranteed.

[0004] The utility model is realized by adopting the following technical scheme: a liquid water-soluble fertilizer grinding device, comprising a front liquid fertilizer storage tank, a colloid mill and a vibrating screen, the colloid mill is installed on the upper side of the front liquid fertilizer storage tank, a liquid extraction pipe is installed in the front liquid fertilizer storage tank, the liquid extraction pipe is connected to a pump, the pump is connected to the feed hopper of the colloid mill through a water pipe, a first liquid outlet is provided on the lower side of the colloid mill, the vibrating screen comprises a frame, a screen is installed on the top of the frame, the front end of the screen is below the first liquid outlet of the colloid mill, the frame is installed on the lower side of the screen, a vibration motor is installed on the shell, a second liquid outlet is provided on the bottom of the shell, the screen is arranged to be tilted downward from front to rear, a first feed inlet is provided on the top of the front liquid fertilizer storage tank, and the rear end of the screen is above the first feed inlet of the front liquid fertilizer storage tank.

[0010] Furthermore, a stirring motor is installed on the top of the front liquid fertilizer storage tank, the stirring motor is connected to a stirring shaft, and the stirring shaft is inserted into the front liquid fertilizer storage tank.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] Compared with the liquid water-soluble fertilizer grinding device in the prior art, the utility model improves the circulation grinding method, and there is no need to set a feeding pipe at the liquid outlet of the colloid mill. The utility model adds a vibrating screen at the first liquid outlet of the colloid mill. When realizing the circulation grinding, the utility model only needs to pass the liquid water-soluble fertilizer with the particle size meeting the requirements through the second liquid outlet to the rear liquid fertilizer storage tank through the vibrating screen, and pass the liquid water-soluble fertilizer with the particle size too large and not meeting the requirements into the first feed port of the front liquid fertilizer storage tank through the rear end of the vibrating screen, and make this part of the liquid water-soluble fertilizer with the particle size too large be re-delivered to the colloid mill for grinding through the liquid extraction pipe and the pump, thereby realizing the circulation grinding of the liquid water-soluble fertilizer. The utility model avoids the repeated grinding of the water-soluble fertilizer with the particle size meeting the requirements by improving the circulation grinding method, effectively improves the grinding efficiency of the liquid water-soluble fertilizer, and is suitable for large-scale continuous production of liquid water-soluble fertilizer.

[0013] The utility model can screen the ground liquid water-soluble fertilizer by arranging a vibrating screen, so that the water-soluble fertilizer meeting the particle size requirements enters the rear liquid fertilizer storage tank, thereby well ensuring the production quality of the liquid water-soluble fertilizer.
