Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of building material mechanism sand and stone, especially relates to a sand and stone aggregate anti -blocking stirring device. BACKGROUND

[0002] As the most basic and indispensable building material in engineering construction, the importance of sand and stone is self-evident.However, in the production and processing process of sand and stone aggregate, sand often encounters some tricky problems when passing through the silo link.Especially when the sand contains excessive stone powder, these tiny stone powder particles are easy to adhere to each other inside the silo, forming a hard block structure, i.e., the case of hardening.This situation not only greatly reduces the flowability of sand in the silo, but also easily causes blockage and poor discharging problems, thereby seriously affecting the continuity and stability of the production line.

[0003] More complex is that if the sand adopts a wet production process, the moisture in the sand is easy to freeze in areas with low temperature.Once frozen, the adhesion between the sand will greatly increase, making the originally easy-to-block silo problem more serious.The formation of ice blocks not only hinders the normal flow of sand, but also may cause additional wear to the silo wall, and even cause equipment failure.

[0004] In the face of these problems, the traditional solution is often to take the manual dredging way.This usually requires first chiseling the concrete on top of the sand silo, and then the workers enter the silo interior for cleaning and dredging.This process not only takes time and effort, but also has high cost.More importantly, manual dredging often cannot completely solve the problem, leaving hidden dangers, affecting the subsequent production efficiency and product quality. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a sand and stone aggregate anti-blocking stirring device to solve the problem of sand silo sand blocking the discharge port.

[0006] To solve the above technical problems, the utility model adopts the technical scheme of:

[0007] A sand and stone aggregate anti-blocking stirring device, the anti-blocking stirring device 3 is arranged on the sand silo 4, the anti-blocking stirring device 3 is composed of a driving structure 3-1, a spiral rod 3-2 and a spiral blade 3-3;

[0008] The driving structure 3-1 is fixed on the top of the sand silo 4, one end of the spiral rod 3-2 is connected with the driving end of the driving structure 3-1, and the spiral blade 3-3 is uniformly arranged on the spiral rod 3-2.

[0009] Further, the spiral diameter of the anti-blocking stirring device is 1000mm.

[0010] Furthermore, the length of the screw rod of the anti-clogging stirring device is 6m.

[0011] Furthermore, the pitch of the anti-clogging stirring device is 560mm.

[0012] Furthermore, the rotation speed of the anti-clogging stirring device is 32 r / min.

[0013] Furthermore, the conveying capacity of the anti-clogging mixing device is 300 m³ / h.

[0014] This invention provides a sand and gravel aggregate anti-clogging mixing device. Once a blockage is detected at the discharge port, the device can be quickly activated. The spiral mixing device, with its unique spiral structure and powerful driving force, can penetrate deep into the silo to strongly agitate and mix the blocked sand. Through this process, densely packed, difficult-to-flow sand will be effectively dispersed, and the blockage point will be quickly cleared, ensuring that the sand can be smoothly discharged from the discharge port. This innovative solution not only greatly improves the efficiency of solving blockage problems but also effectively reduces the cost and risk of manual unblocking, providing a strong guarantee for the continuity and stability of sand and gravel aggregate production.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] This utility model embodiment provides a sand and gravel aggregate anti-clogging mixing device, such as... Figure 1 As shown, it includes a drive structure installed on the upper part of the sand silo. Figure 3 (3-1); A helical rod is connected below the drive structure ( Figure 3 (3-2) Spiral blades are evenly arranged on the spiral rod. Figure 3The screw rod and the helical blade rotate under the drive of the driving structure.

[0021] As shown in Figure 2 and Figure 3 The sand is stably transported by the high-efficiency belt conveyor, and the sand is smoothly guided into two sand bins with sufficient capacity through the precisely designed sand distribution chute. Under the natural action of gravity, the sand flows along the sand bin to the conical hopper, and finally converges to the receiving port of the mobile bulk machine. The mobile bulk machine uniformly and accurately distributes the received sand to the belt conveyor below. The belt conveyor carries the sand smoothly until it reaches the unloading area (yellow module in the figure) at the tail of the belt conveyor. The unloader accurately unloads the sand onto the truck waiting below. This series of processes marks the completion of the complete loading process from transportation, distribution to loading.

[0022] In this process, if there is an excessive amount of stone powder in the sand, or if the sand is produced by a wet process, especially in a low-temperature environment, the moisture in the sand is likely to freeze. Both of these factors can easily cause the sand bin to become caked. Caking refers to the phenomenon that the sand in the sand bin is bonded together due to excessive humidity, low temperature, or other reasons, forming a hard block structure, which causes the sand to be blocked in the sand bin and the sand to flow poorly. This caking not only affects the normal transportation and distribution efficiency of the sand, but also can cause additional wear and tear to the equipment, and even cause production failures, so it must be paid enough attention and appropriate preventive measures must be taken to solve it.

[0023] When the sand bin is blocked, simply turn on the driving structure switch of the anti-blocking stirring device, and the screw rod and the helical blade will start to rotate upward under the powerful power of the motor. This movement process cleverly pulls the sand at the bottom of the bin to make it move upward, while the anti-blocking stirring device remains relatively stationary. In this process, the material that was originally accumulated in the middle of the discharge port and in a stationary state will be disturbed strongly. At the same time, the material on both sides that was blocked also finds a way out under this disturbance, and they flow out smoothly through the hollow discharge channel, and the flow of sand in the bin resumes smoothly, thereby realizing the normal discharging process. The application of this device not only solves the problem of sand bin blockage, but also greatly improves the efficiency and smoothness of material handling.

[0024] The anti-blocking stirring device is composed of a screw rod, a helical blade, and a driving structure. The screw rod is composed of a head bearing, a tail bearing, a suspension bearing, and a base. The driving structure is composed of a motor, a speed reducer, a coupling, and a base.

[0025] The screw diameter of the anti-blocking stirring device is set to 1000mm, the length is 6m, the pitch is 560mm, the rotating speed is 32r / min, and the conveying capacity is 300m 3 / h. The power can be calculated according to the following formula: 24.59kW.

[0028] D represents the diameter of the screw conveying type stirring device, m;

[0029] L represents the length of the screw conveying type stirring device, m;

[0032] Motor power

[0033] In the formula, η represents the total efficiency of the driving device, and generally, η=0.85~0.9.

[0034] The sand and gravel aggregate anti-blocking stirring device can ensure that the sand and gravel can be smoothly discharged from the discharge port. The innovative scheme not only greatly improves the efficiency of solving the blocking problem, but also effectively reduces the cost and risk of manual dredging, and provides a powerful guarantee for the continuity and stability of sand and gravel aggregate production.
