Abstract
Description
Technical Field
[0001] This utility model relates to the field of material packaging technology and is a device for preventing blockage during the feeding of caustic soda flakes packaging scale. Background Technology
[0002] Currently, automated packaging equipment is used to weigh and package the caustic soda flakes produced by the caustic soda flake unit in the caustic soda workshop. During the feeding process of the automated packaging equipment, the caustic soda flakes are prone to deliquescence and stick to the walls. This sticking affects the feeding speed and weighing accuracy, and severe sticking can lead to blockages. Regular cleaning of the scales is necessary, impacting the unit's production capacity. Furthermore, the automated packaging equipment performs weighing, feeding, and sealing operations in the caustic soda flake production process. A malfunction in any of these operations can disrupt normal production, resulting in a relatively high failure rate for the automated packaging equipment. When the solid caustic soda unit in the caustic soda workshop is operating under heavy load, regular maintenance of the automated packaging equipment is required, and the caustic soda flake unit also needs to operate at a reduced load, further affecting caustic soda production. Summary of the Invention
[0003] This utility model provides a feeding anti-blocking device for caustic soda packaging scales, which overcomes the shortcomings of the prior art and can effectively solve the problem of material sticking to the wall and accumulating in the caustic soda silo of existing automatic packaging equipment.

[0005] The following are further optimizations and / or improvements to the above-mentioned utility model technical solution:
[0006] The aforementioned feed pipe may include an upper straight pipe section, a cooling pipe section, and a lower straight pipe section that are fixedly connected together from top to bottom, with a cooling sleeve provided on the outside of the cooling pipe section.

Detailed Implementation
[0014] This utility model is not limited to the following embodiments, and the specific implementation method can be determined according to the technical solution of this utility model and the actual situation.
[0015] Unless otherwise specified, all equipment and devices used in this invention are existing and commonly known in the field. For example, the screw conveyor 2, the fully automatic packaging machine 9, the semi-automatic packaging machine 10, and the weighing display and control instrument 15 are existing and commonly known equipment.
[0016] In this utility model, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as the positional relationships of front, back, top, bottom, left, and right, which are based on the instructions attached. Figure 1 The orientation of the layout is determined by the direction of the map.
[0017] The present invention will be further described below with reference to the embodiments and accompanying drawings:
[0018] Example 1: As shown in the attached document Figure 1 As shown, the anti-clogging device for the caustic soda packaging scale includes a frame 1, a screw conveyor 2, a drive motor 3, a receiving hopper 4, a fully automatic packaging machine 9, a semi-automatic packaging machine 10, and at least one weighing and discharging device. The screw conveyor 2 is horizontally mounted on the frame 1. The screw conveyor 2 is equipped with a drive motor 3 that allows it to convey materials from left to right or from right to left. A receiving hopper 4 is located at the upper inlet of the screw conveyor 2. Weighing and discharging devices are located at both the lower left and lower right outlets of the screw conveyor 2. Below the weighing and discharging device on the left side is a fully automatic packaging machine 9, a semi-automatic packaging machine 10, and at least one weighing and discharging device. The automatic packaging machine 9 is located below the weighing and feeding device on the right side, and a semi-automatic packaging machine 10 is provided. The weighing and feeding device includes a feeding pipe and a weighing hopper 8. The feeding pipe is provided at the lower left outlet of the screw conveyor 2. The weighing hopper 8 is provided below the feeding pipe. A vibration motor 17 is fixedly installed at the lower part of the weighing hopper 8. A support frame 19 is fixedly installed at the lower part of the weighing hopper 8. An air cannon 18 is provided on the upper side of the support frame 19. An air inlet is provided on the weighing hopper 8 corresponding to the position of the air cannon 18. An exhaust pipe is fixedly connected between the air outlet of the air cannon 18 and the air inlet of the weighing hopper 8.
[0019] During use, the vibration motor 17 is controlled to shake down the caustic soda flakes that have accumulated and adhered in the weighing hopper 8. After the air cannon 18 reaches the set pressure, the air cannon 18 discharges high-pressure gas into the weighing hopper 8 to back-blow down the accumulated and adhered caustic soda flakes, keeping the weighing hopper 8 unobstructed. The vibration motor 17 and the air cannon 18 can effectively reduce the accumulation and adhesion of caustic soda flakes in the weighing hopper 8 and reduce the caking of caustic soda flakes in the weighing hopper 8.
[0020] In addition, in this utility model, the caustic soda flakes from the caustic soda flake machine are sent to the screw conveyor 2 through the receiving hopper 4. The caustic soda flakes are sent from right to left through the screw conveyor 2 to the weighing and feeding device located on the left side of the screw conveyor 2, and then sent to the fully automatic packaging machine 9 for packaging. When the caustic soda flake machine is operating under heavy load and the fully automatic packaging machine 9 needs regular maintenance, the packaging process is switched from fully automatic packaging to semi-automatic packaging. The caustic soda flakes are sent from left to right through the screw conveyor 2 to the weighing and feeding device located on the right side of the screw conveyor 2, and then sent to the semi-automatic packaging machine 10 for packaging. Timely maintenance of the fully automatic packaging machine 9 is performed without affecting the normal operation of the process.
[0021] The above-mentioned anti-blocking device for the caustic soda flake packaging scale can be further optimized and / or improved according to actual needs:
[0022] Example 2: Its difference from Example 1 is as follows: (See attached) Figure 1 As shown, the feeding pipe includes an upper straight pipe section 5, a cooling pipe section 6, and a lower straight pipe section 7 that are fixedly connected together from top to bottom. A cooling sleeve is provided on the outside of the cooling pipe section 6.
[0023] During operation, by installing a cooling jacket, the freshly produced caustic soda (typically between 50°C and 60°C) can be effectively cooled. This allows for immediate stacking of the packaged caustic soda and reduces caking within the weighing hopper 8. Ultimately, this improves product quality and packaging efficiency, and reduces material buildup on the walls of the weighing hopper 8. Depending on the requirements, the cooling jacket can employ water cooling or air cooling, both commonly known in the art.
[0024] Example 3: It differs from Example 2 in that the cooling pipe section 6 is inclined with the left side lower and the right side higher.
[0025] During use, the tilted design is intended to cushion the material and extend the cooling time.
[0026] Example 4: It differs from Examples 1 to 3 in that the weighing hopper 8 has a non-stick coating on its inner side.
[0027] During use, the inner surface of the weighing hopper 8 is coated with a non-stick coating, which effectively reduces the problem of material sticking to the wall of the weighing hopper 8.
[0028] Example 5: It differs from Example 4 in that the non-stick coating is a Teflon coating.
[0029] As needed, Teflon coating is a fluorocarbon coating. The inner surface of the weighing hopper 8 treated with Teflon coating can simultaneously possess a variety of superior functions, such as: non-stick, high temperature resistance, low friction, corrosion resistance, anti-sticking and moisture-proof properties, and high insulation, which further improves the working performance of the weighing hopper 8.
[0030] Example 6: Its difference from Examples 1 to 5 is as follows: (See attached) Figure 1 As shown, it also includes a control module. The weighing hopper 8 is equipped with a level transmitter 11, the receiving hopper 4 has a high level transmitter 12 on the upper outer side, the receiving hopper 4 has a low level transmitter 13 on the lower outer side, the receiving hopper 4 has a discharge main valve 14, the weighing hopper 8 has a weighing display controller 15, and the weighing hopper 8 has a discharge valve 16 at the bottom outlet. The control module is connected to the level transmitter 11, the high level transmitter 12, the low level transmitter 13, the discharge main valve 14, the weighing display controller 15, the discharge valve 16, and the drive motor 3, respectively.
[0031] During use, the control module controls the drive motor 3 to make the screw conveyor 2 transport caustic soda flakes from right to left to the weighing and feeding device on the left. When the level transmitter 11 detects that the caustic soda flakes in the weighing hopper 8 have reached the set value, the control module controls the drive motor 3 to make the screw conveyor 2 transport caustic soda flakes from left to right to the weighing and feeding device on the right. This can effectively switch between the fully automatic packaging machine 9 and the semi-automatic packaging machine 10 at any time, reduce the high load operation of the fully automatic packaging machine 9, and ensure that the packaging of caustic soda flakes is not affected.
[0032] The high-level transmitter 12 and the low-level transmitter 13 can monitor the amount of caustic soda flakes in the receiving silo 4 in real time, and finally send it to the screw conveyor 2 through the discharge valve 14. When the high-level transmitter 12 detects that the amount of caustic soda flakes in the receiving silo 4 has reached the highest set value, it controls the discharge valve 14 to open. When the low-level transmitter 13 detects that the amount of caustic soda flakes in the receiving silo 4 has reached the lowest set value, it controls the discharge valve 14 to close.
[0033] The caustic soda flakes in the weighing hopper 8 are weighed and measured by the weighing display controller 15, and then discharged into the fully automatic packaging machine 9 for packaging through the discharge valve 16. The weighing and discharging device on the right side adopts the same steps and is packaged through the semi-automatic packaging machine 10. The control module controls the discharge valve 16 to open. After the weighing display controller 15 monitors the weighing and measurement of the caustic soda flakes to the set value, the control module controls the discharge valve 16 to close, and the weighed and measured caustic soda flakes are discharged into the fully automatic packaging machine 9 for packaging. Similarly, the weighing and discharging device on the right side adopts the same steps to discharge the weighed and measured caustic soda flakes into the semi-automatic packaging machine 10 for packaging.
[0034] Depending on the needs, the pipelines and equipment of the caustic soda packaging scale's anti-clogging device can also be equipped with conventional valves, thermometers, and pressure gauges known in the art, according to production requirements. The control module is a DCS controller, and the DCS controller model can be the CS3000 controller manufactured by Yokogawa Corporation of Japan.
[0035] The above technical features constitute the embodiments of this utility model, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
[0036] The usage process of this utility model embodiment is as follows: First, the caustic soda flakes from the caustic soda flake machine are sent to the screw conveyor 2 through the receiving hopper 4. The caustic soda flakes are sent from right to left through the screw conveyor 2 to the weighing and feeding device on the left side for storage. After being weighed by the weighing display controller 15, the weighed caustic soda flakes are sent to the fully automatic packaging machine 9 for packaging. When the caustic soda flake machine is operating under heavy load and the fully automatic packaging machine 9 needs regular maintenance, the caustic soda flakes are sent from left to right through the screw conveyor 2 to the weighing and feeding device on the right side for storage. After being weighed, the weighed caustic soda flakes are sent to the semi-automatic packaging machine 10 for packaging.
