Abstract
Description
Technical Field
[0001] This utility model belongs to the field of anti-caking agent preparation technology, and in particular relates to a novel automated anti-caking agent addition system. Background Technology
[0002] Currently, the following defects exist in the process of adding anti-caking agent for ammonium chloride during the production of soda ash: (1) The anti-caking agent is added by gravity flow from the high-level tank and valve control. As the liquid level in the high-level tank drops, the addition rate will also change. The amount of anti-caking agent added cannot be kept in a certain proportion with the output of ammonium chloride, resulting in inconsistent addition ratio of additives; (2) The anti-caking agent for wet ammonium is added from the wet ammonium discharge port. The anti-caking agent cannot be mixed evenly with the wet ammonium, resulting in some wet ammonium caking during storage, causing inconsistent product quality. At the same time, the addition of anti-caking agent to wet ammonium also increases the moisture content; (3) The anti-caking agent for dry ammonium is added before drying. During the drying process, this part of the water needs to be dried, which increases the energy consumption of soda ash and increases the production cost; (4) At present, no anti-caking agent is added to the wet ammonium at the centrifuge and wet ammonium belt conveyor, which causes the centrifuge discharge chute and belt box to frequently scab, causing inconvenience to production; (5) When preparing the anti-caking agent, the original circulating pump is used, which is labor-intensive and complicated. Utility Model Content
[0003] Technical problem solved: In view of the problems existing in the background technology, this utility model provides a new type of automated anti-caking agent addition system, which can automatically adjust the amount of anti-caking agent added according to the production load, thus solving the problem that the amount of anti-caking agent added cannot be accurately matched with the output; at the same time, by changing the addition position, it solves the problem that uneven mixing of wet ammonium products and anti-caking agents causes some products to easily caking.
[0004] Technical solution: The present invention discloses a novel automated anti-caking agent addition system, which includes a circulation tank, a tap water pipe and an anti-caking agent inlet pipe connected to the circulation tank, and a tap water self-control valve and a self-priming pump connected to the tap water pipe and the anti-caking agent inlet pipe, respectively.
[0005] The bottom of the circulation tank is connected to a main circulation pipe and a circulation pump connected to the main circulation pipe. The end of the main circulation pipe is connected to a circulation branch pipe and an external delivery pipe connected to the top of the circulation tank. A circulation self-control valve is connected to the circulation branch pipe, and an external delivery self-control valve is connected to the external delivery pipe.
[0006] The top of the circulation tank is equipped with a circulation tank level gauge and a timer. The circulation tank level gauge is interlocked with the self-priming pump, the tap water self-control valve, the circulation pump and the timer respectively. The timer is interlocked with the circulation self-control valve and the external supply self-control valve. The circulation pump is interlocked with the circulation self-control valve and the external supply self-control valve.
[0007] Preferably, the end of the delivery pipeline is connected to a storage tank, and a storage tank level gauge is installed at the top of the storage tank. The storage tank level gauge is interlocked with the delivery automatic control valve.
[0008] Preferably, the bottom of the storage tank is connected to an anti-caking agent delivery pipe, and an anti-caking agent flow meter and an anti-caking agent self-control valve are connected to the anti-caking agent delivery pipe.
[0009] Preferably, the anti-caking agent delivery pipeline is connected in parallel to the centrifuge inlet pipeline and connected to the centrifuge inlet end. An inlet flow meter is connected to the centrifuge inlet pipeline, and the anti-caking agent flow meter is interlocked with the anti-caking agent self-control valve and the inlet flow meter.
[0010] Preferably, an automatic inlet control valve is connected to the centrifuge inlet pipe, and the centrifuge inlet pipe is connected to the main inlet valve at the centrifuge inlet end.
[0011] Compared with the prior art, the present invention has the following beneficial effects.
[0012] This invention can automatically adjust the amount of anti-caking agent added according to the production load, solving the problem that the amount of anti-caking agent added cannot be precisely matched with the output. At the same time, changing the addition position solves the problem that uneven mixing of wet ammonium products and anti-caking agents causes some products to easily clump. Setting the anti-caking agent addition position at the inlet of each centrifuge can avoid the increase in energy consumption of dry ammonium furnace due to the addition of anti-caking agent. The use of automated interlocking control can significantly reduce the operation steps of preparing and conveying anti-caking agent solution, reducing the labor intensity of operation.

Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings. Figure 1 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0017] like Figure 1 As shown, this utility model discloses a novel automated anti-caking agent addition system. The anti-caking agent addition system includes a circulation tank 1, with a tap water pipe 16 and an anti-caking agent inlet pipe 17 connected to the circulation tank 1. A tap water self-control valve 7 and a self-priming pump 3 are respectively connected to the tap water pipe 16 and the anti-caking agent inlet pipe 17. A circulation main pipe 18 and a circulation pump 4 connected to the circulation main pipe 18 are connected to the bottom of the circulation tank 1. A circulation branch pipe 19 and an external delivery pipe 20 connected to the top of the circulation tank 1 are respectively connected to the end of the circulation main pipe 18. A circulation self-control valve 5 is connected to the circulation branch pipe 19, and an external delivery self-control valve 9 is connected to the external delivery pipe 20. A circulation tank level gauge 6 and a timer 8 are installed at the top of the circulation tank 1. The circulation tank level gauge 6 is interlocked with the self-priming pump 3, the tap water self-control valve 7, the circulation pump 4, and the timer 8. The timer 8 is interlocked with the circulation self-control valve 5 and the external delivery self-control valve 9. The circulation pump 4 is interlocked with the circulation self-control valve 5 and the external delivery self-control valve 9. During the preparation of the anti-caking agent dilution solution, the inlet hose of the self-priming pump 3 is inserted into the stock solution tank. Starting the self-priming pump 3 draws the anti-caking agent stock solution into the circulation tank 1. When the liquid level in the circulation tank 1 reaches 25%, the self-priming pump 3 automatically stops, and the tap water self-control valve 7 automatically opens via interlock control to allow tap water to enter. When the liquid level reaches 85% (the mixing ratio of anti-caking agent to tap water can be set as needed, as well as the anti-caking agent level and the level after adding tap water), the tap water self-control valve 7 automatically closes, and the timer 8 starts simultaneously. A preset time of 30 minutes (the timer duration can be set as needed) triggers the automatic opening of the circulation self-control valve 5, and the automatic opening of the circulation pump 4 via interlock control. The circulation pump 4 draws the solution from the circulation tank 1 to circulate and mix the anti-caking agent solution. After the timer 8 expires, the circulation self-control valve 5 and the circulation pump 4 are closed, thus completing the preparation of the anti-caking agent dilution solution.
[0018] A storage tank 2 is connected to the end of the external delivery pipeline 20. A storage tank level gauge 10 is installed at the top of the storage tank 2. The storage tank level gauge 10 is interlocked with the external delivery automatic control valve 9. After the external delivery automatic control valve 9 is opened, the prepared anti-caking agent solution can be pumped into the storage tank 2 for storage by the circulation pump 4. When the storage tank level gauge 10 detects that the liquid level in the storage tank 2 is lower than 10%, the external delivery automatic control valve 9 is automatically opened, and the circulation pump 4 is automatically started to send the prepared anti-caking agent solution into the storage tank 2. When the liquid level in the circulation tank 1 reaches 10%, the external delivery automatic control valve 9 is automatically closed, and the circulation pump 4 stops sending liquid, and a new round of anti-caking agent solution preparation process begins.
[0019] An anti-caking agent delivery pipe 21 is connected to the bottom of storage tank 2. A dosing pump 11, an anti-caking agent flow meter 12, and an anti-caking agent self-control valve 13 are connected to the anti-caking agent delivery pipe 21. The anti-caking agent delivery pipe 21 is connected in parallel to the centrifuge inlet pipe 22 and connected to the inlet of centrifuge 15. An inlet flow meter 14 is connected to the centrifuge inlet pipe 22. The anti-caking agent flow meter 12 is interlocked with the anti-caking agent self-control valve 13 and the inlet flow meter 14. The dosing pump 11 can be used to increase the outlet pressure of the anti-caking agent solution and maintain a stable supply pressure of the anti-caking agent solution. Changing the anti-caking agent solution dosing port from the wet ammonium feed port or the fluidized bed wet ammonium inlet to the inlet of each centrifuge 15 can avoid increased energy consumption in the dry ammonium furnace due to the addition of anti-caking agent. A flow meter 14 is installed on the inlet pipe of centrifuge 15, and an anti-caking agent flow meter 12 and an anti-caking agent self-control valve 13 are connected to the anti-caking agent delivery pipe 21. The anti-caking agent solution is directly pumped into the inlet pipe of centrifuge 15 by the addition pump 11 and mixed with ammonium chloride slurry. Through automatic addition control logic, the anti-caking agent solution is added at 0.5% of the ammonium chloride slurry flow rate. The anti-caking agent flow meter 12 is set to 0.5% of the inlet flow rate of centrifuge 15. The actual flow rate of the anti-caking agent delivery pipe 21 is compared with the set flow rate. By adjusting the opening of the anti-caking agent self-control valve 13, when the production volume is adjusted, the inlet volume of ammonium chloride slurry changes, and the corresponding anti-caking agent addition amount is also automatically adjusted. This achieves the goal of always adding the anti-caking agent solution in proportion and solves the problem that the anti-caking agent addition amount cannot be accurately matched with the production volume. Furthermore, the anti-caking agent is now added directly to the ammonium chloride slurry. After separation by centrifuge 15, its effective substances can be evenly distributed in the ammonium chloride product, avoiding the partial scaling problem caused by uneven mixing of wet ammonium product and anti-caking agent. Secondly, the addition point is moved to the inlet of centrifuge 15. The separated wet ammonium already carries anti-caking agent, which can effectively prevent scaling in the centrifuge 15 chute and belt box. Since the excess water of the anti-caking agent is thrown out by centrifuge 15, the wet ammonium will not introduce excess water before entering the fluidized bed, thereby reducing the energy consumption of the dry ammonium furnace.
[0020] An automatic inlet valve 23 is connected to the centrifuge inlet pipe 22. The automatic inlet valve 23 can control the entry or stop of ammonium chloride slurry. A main inlet valve 24 is connected to the centrifuge inlet pipe 22 at the inlet end of the centrifuge 15. The main inlet valve 24 can control the entry or stop of ammonium chloride slurry and anti-caking agent.
[0021] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
