Description

Technical Field

[0001] The invention relates to the field of dry mortar bulking, in particular to a dry mortar bulking machine. Background Art

[0002] Dry-mixed mortar is a new product in the building materials industry. Most of them are made by mixing cement and other materials such as fly ash, and adding some materials such as dried sand, and mixing them through a dry mixing process. Dry-mixed mortar is bulked through loading containers such as loading bags, or directly transported in bulk by loading trucks. That is, the traditional bulk form of dry-mixed mortar is unloading and filling, and unloading is only a simple opening for unloading. If a certain amount of powdered mortar is accumulated, the discharge port is prone to blockage, so it is necessary to improve the discharge port of dry-mixed mortar;

[0003] At present, Chinese patent CN216189415U discloses a technical solution, which is to set an extrusion screw in the discharge port of the dry mortar bulk machine, and actively push the dry mortar to discharge through an external drive component, which can avoid the mortar being blocked at the outlet; however, although the extrusion screw in this solution can actively push the dry mortar to discharge, due to the obstruction of the blades of the extrusion screw, the dry mortar also loses the ability to fall independently by gravity, resulting in the need for continuous reliance on power to discharge the dry mortar. In the long-term operation of the dry mortar bulk machine, the energy consumption increases and cannot be ignored, which is not conducive to energy conservation and emission reduction in large industrial sites;

[0004] In view of the above technical problems, this application proposes a solution. Summary of the invention

At the same time, the crushing rod can be automatically started and stopped through system control to avoid the problem of increased energy consumption due to the continuous rotation of the crushing rod. This solves the problem that the discharge port of the free-fall dry-mix mortar bulk machine is prone to blockage, and the active output structure will cause the energy consumption of the dry-mix mortar bulk machine to increase, and a dry-mix mortar bulk machine is proposed.

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figure 1 - Figure 5 As shown, a dry mortar bulk packing machine includes a storage tank 1, and a feed port is provided on the top of the storage tank 1. The feed port is used to pour dry mortar from a production site into the storage tank 1, and further bulk pack it through the storage tank 1;

[0036] A discharge hopper 2 is fixedly installed below the storage tank 1, and the interior of the discharge hopper 2 forms an integral body with the interior of the storage tank 1. The discharge hopper 2 is in an inverted cone shape, and a discharge port 3 is fixedly connected below the discharge hopper 2. A bulk material ring 6 is rotatably connected to the middle of the discharge port 3. The top and bottom ends of the discharge port 3 are both annular structures to ensure the stability of the bulk material ring 6. A rectangular window is opened on the outer wall of the discharge port 3, and the rectangular window and the bulk material ring 6 are located at the same height, so that a part of the bulk material ring 6 can be exposed through the rectangular window;

[0037] A vertical gear groove is provided on the outer wall of the bulk material ring 6, and a driving structure 5 is installed on the outer wall of the discharge port 3. The driving structure 5 is installed below the rectangular window. The driving structure 5 includes a motor, a transmission box and an output gear. The motor is powered by an external power supply and drives the output gear to rotate through the transmission box. The edge of the output gear is located in the rectangular window and meshes with the gear groove on the outer wall of the bulk material ring 6. When the output gear rotates, it drives the bulk material ring 6 to rotate.

[0038] A crushing rod 7 is fixedly mounted on the inner wall of the bulk ring 6. The crushing rod 7 is divided into two sections. The lower end is vertically arranged, and the upper section is obliquely arranged and close to the discharge hopper 2. At the same time, the upper section of the crushing rod 7 is a wave-like structure.

[0039] An adjustment assembly 4 is installed at the bottom end of the discharge port 3, and the adjustment assembly 4 is divided into a positive adjustment pipeline 41 and a reverse adjustment pipeline 42, wherein the positive adjustment pipeline 41 and the reverse adjustment pipeline 42 are both arc-shaped structures, and the positive adjustment pipeline 41 and the reverse adjustment pipeline 42 are rotatably connected, and the connection can be driven by a motor, and the positive adjustment pipeline 41 and the discharge port 3 are also rotatably connected and driven by a motor.

[0040] Example 2: Please refer to Figure 1 - Figure 5 As shown, the bottom of the discharge port 3 is a solid flow meter, which counts the dry powder flow passing through it, and calculates the dry powder flow rate based on the dry powder flow change between two time points and the time difference between the two time points;

[0041] The mortar bulk loader control system includes a flow rate monitoring unit, a flow rate control unit, a change analysis unit and an adjustment control unit;

[0042] The flow rate monitoring unit obtains collected information through the solid flow meter in the discharge port 3, wherein the collected information includes the dry powder flow rate and the dry powder flow rate. The flow rate monitoring unit compares the obtained dry powder flow rate with the set flow rate threshold. If the powder flow rate is less than the set flow rate threshold, a discharge blockage signal is generated. If the powder flow rate is greater than or equal to the set flow rate threshold, a discharge normal signal is generated.

[0043] After the flow rate control unit obtains the abnormal discharge signal through the flow rate monitoring unit, it generates a rotation breaking signal, and the flow rate control unit sends the rotation breaking signal to the controller, and the controller converts the rotation breaking signal into a control instruction, and controls the bulk ring 6 to rotate through the control instruction. During the rotation process, the bulk ring 6 drives the breaking rod 7 installed on its inner wall to move in a circular motion inside the discharge hopper 2, so that the dry powder attached to the inner wall of the discharge hopper 2 is broken and falls off by the breaking rod 7, so as to prevent the dry powder from sticking or forming an arched structure inside the discharge hopper 2 when the valve of the discharge port 3 is closed;

[0044] After the flow rate control unit obtains the normal discharge signal through the flow rate monitoring unit, it generates a rotation stop signal and sends the rotation stop signal to the controller. The controller converts the rotation stop signal into a control instruction, thereby stopping the rotation of the bulk material ring 6;

[0045] The variation analysis unit obtains the dry powder flow rate through the flow rate monitoring unit, and records the time when the dry powder flow rate is obtained, and obtains the dry powder flow rate variation curve by one-to-one correspondence between the time and the dry powder flow rate. The variation analysis unit obtains the rotational crushing signal through the flow rate control unit, and marks the time corresponding to the acquisition of the rotational crushing signal in the dry powder flow rate variation curve;

[0046] The variation analysis unit selects the dry powder flow rate within the time length t behind the rotational crushing signal in the dry powder flow rate variation curve, and calculates the average value of the dry powder flow rate within the time length t, and records the calculation result as the optimized flow rate. The variation analysis unit compares the optimized flow rate with the set optimization threshold value. If the optimized flow rate is greater than the set optimization threshold value, an optimization normal signal is generated. If the optimized flow rate is not greater than the set optimization threshold value, an optimization abnormal signal is generated.

[0047] The change analysis unit sends the optimization abnormality signal to the management device through the network, and the management device displays the optimization abnormality signal through a display screen.

[0048] The variation analysis unit obtains the time interval between two adjacent groups of rotational crushing signals in the dry powder flow rate variation curve, and records it as the optimization interval. The variation analysis unit obtains all the optimization intervals, and performs arithmetic averaging on the obtained optimization intervals to obtain the optimization interval mean value;

[0049] The change analysis unit performs a threshold analysis on the optimized interval mean. If the optimized interval mean is greater than the set threshold, a normal interval signal is generated. If the optimized interval mean is not greater than the set threshold, an abnormal interval signal is generated. The change analysis unit sends the abnormal interval signal to the management device through the network, and the management device displays the abnormal interval signal through the display device.

[0050] Example 3: Please refer to Figure 1 - Figure 5 As shown, the adjustment control unit obtains the current angles of the positive adjustment pipeline 41 and the reverse adjustment pipeline 42 through the sensor, and when adjusting the outlet direction of the adjustment combination 4, generates separate rotation angle signals for the positive adjustment pipeline 41 and the reverse adjustment pipeline 42, controls the positive adjustment pipeline 41 and the reverse adjustment pipeline 42 to rotate to the corresponding angles, thereby realizing the adjustment of the discharge direction through the mutual combination of the positive adjustment pipeline 41 and the reverse adjustment pipeline 42.
