Description

Technical Field

[0001] This utility model relates to the field of cement processing technology, and in particular to a cement grinding aid addition and adjustment component. Background Technology

[0002] Cement grinding aids are additives used in the cement production process, typically in cement grinding systems to improve grinding efficiency. These grinding aids enhance the operating efficiency of cement grinding systems and play a role in aiding grinding and improving efficiency during cement preparation. Their main functions include reducing energy consumption of the grinding system, increasing the fineness of the cement, and adjusting the early strength of the cement. These grinding aids are usually added to cement grinding systems in liquid or solid form to optimize the cement production process. Common cement grinding aids include silicate grinding aids and polycarboxylate grinding aids.

[0003] However, this patent still has shortcomings. Although it can achieve a certain effect of adding cement grinding aid in use, the existing cement grinding aid adding device lacks the effect of adaptive addition of appropriate amount of cement grinding aid, which makes it impossible to add the appropriate amount of grinding aid, which can easily reduce the cement mixing effect and waste resources. In view of this, we propose a cement grinding aid adding adjustment component to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a cement grinding aid addition and adjustment component.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cement grinding aid addition and adjustment component, comprising a box, a hydraulic cylinder, a water tank, and an installation box. The installation box is provided on one outer wall of the box, and a water tank is fixed inside the installation box. A hydraulic cylinder is provided on one side of the water tank. A buffer tank is provided inside the upper end of the hydraulic cylinder, and a piston is movably installed inside the buffer tank. A water pump is provided between the hydraulic cylinder and the water tank, and a weighbridge is provided at the lower end of the box.

[0006] During use, this device allows cement to be fed into the tank for rotary mixing. The grinding aid is stored in the water tank using clip one and valve two. As cement is added to the tank, its weight increases, which is detected by a weighbridge. The signal is then transmitted to the installation box via a connecting line. The electrical control components inside the installation box control a hydraulic cylinder to drive a piston upward, pushing the grinding aid from the buffer tank into the tank. The greater the weight, the more is pushed. Initially, the piston is at the bottom. After the control valve is opened, the grinding aid is pumped into the buffer tank. Overall, this device achieves adaptive cement grinding aid addition, optimizing efficiency and reducing waste.

[0007] Preferably, a discharge port is provided on one side of the box body, and a feed port is provided on the upper side of the box body. The feed port can allow cement to be fed into the box body, and after being stirred, it is discharged from the discharge port. The box body is the cement mill body, and the specific structure is not further described. A positioning block is fixed on one side of the mounting box, and the surface of the positioning block is provided with mounting holes. Screws can be used to fix the mounting box to the outer wall of one side of the box body by matching the mounting holes.

[0008] Preferably, a central controller is installed inside the mounting box, and a connecting line connects the weighbridge to the mounting box. The connecting line can connect the central controller and the weighbridge, and the movement stroke of the hydraulic cylinder driven piston is adjusted by using the gravity sensor of the weighbridge.

[0009] Preferably, a valve port one is provided on one side of the outer wall of the installation box, and a valve port two is provided at the upper end of the valve port one. Both valve port one and valve port two are connected to the water tank. The grinding aid can be injected into the valve port two, or the grinding aid can be discharged from the valve port two.

[0010] Preferably, the upper end of the hydraulic cylinder is provided with a hydraulic rod, the upper end of which is fixedly connected to the lower end of the piston. The hydraulic cylinder can drive the piston to move up and down to push the grinding aid inside the buffer tank into the box to participate in the stirring.

[0011] Preferably, the mounting box has an internal mounting groove, and the water pump is fixed to the inner wall of the mounting groove by a mounting base. The mounting groove is used to fix the position of the water pump and achieve the effect of extracting the grinding aid inside the water tank.

[0012] Preferably, the water pump is provided with a control valve at the upper end, and the mounting box is provided with a connecting pipe at the upper end. The control valve is opened when the grinding aid is drawn, closed when the grinding aid is pushed to move at a constant ratio, and needs to be opened when the grinding aid is continuously supplied.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device can use a weighbridge to measure the amount of cement added inside the cement mill, and control the upward movement distance of the hydraulic cylinder according to different weights, thereby adjusting the introduction of an appropriate amount of grinding aid.

[0015] 2. This device can use a control valve to allow the water pump to extract grinding aid from inside the water tank and introduce it into the buffer tank. It can also achieve the effect of adding unlimited dosage. This can be achieved simply by repeatedly driving the hydraulic cylinder and turning on the water pump and control valve. This device can achieve the effects of unlimited addition and fixed-ratio addition, and has high practicality. Attached Figure Description
