Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of quick-setting agents, in particular to a cooling water circulation system for the production of quick-setting agents. Background Art

[0002] Accelerators are additives added to concrete to accelerate its setting and hardening. Their primary ingredient is alumina clinker, a mixture of bauxite, soda ash, and quicklime, sintered in a specific ratio and then ground into a finely ground mixture. Alumina clinker is primarily composed of aluminum oxide, soda ash is sodium carbonate, and quicklime is calcium oxide. The production of accelerators generates significant amounts of heat, particularly when heating or chemical reactions are involved. To maintain the proper operation of production equipment and prevent overheating, effective temperature control is essential, necessitating the use of a cooling water circulation system.

[0003] Common cooling water circulation systems for quick-setting agent production are usually composed of cooling equipment, circulating water pumps, and piping systems. The circulating water pump draws cooling water from the cooling equipment and transports it to the production equipment through the piping system for cooling. The cooled water returns to the cooling equipment for cooling treatment, forming a cycle. This is the common structure and usage of cooling water circulation systems for quick-setting agent production. In traditional cooling water circulation systems for quick-setting agent production, the water source has a short residence time after returning and flowing into the refrigeration area, and the temperature of the circulating cooling water does not meet the cooling requirements. The existing solution is to set the pipes in the refrigeration area in a spiral shape, thereby extending the time for the return water source to pass through the refrigeration area, and cooling the return water source more effectively. However, due to its special structure, the spiral pipe has a relatively weak pressure bearing capacity and is prone to clogging. However, due to its spiral structure characteristics, it is inconvenient to clean. The distance between the spiral structure pipe walls is small, and heat may be transferred, resulting in heat loss. For this reason, a cooling water circulation system for quick-setting agent production is proposed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a cooling water circulation system for the production of quick-setting agent to solve the above-mentioned technical problem that the return water source cannot be fully and effectively cooled.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a cooling water circulation system for producing an accelerating setting agent, comprising:

[0006] An outer shell, and delivery conduits arranged on both sides of the center of the top of the outer shell, and a partition plate is installed horizontally at the center of the inner cavity of the outer shell, and a liquid inlet pump and a liquid discharge pump are respectively connected to both sides of the outer shell;

[0007] The upper heat exchange tube is arranged at the upper part of the inner cavity of the outer shell and is in communication with the delivery conduit. A choke pot is provided at the upper center of the inner cavity of the outer shell and is in communication with the upper heat exchange tube.

[0008] A baffle is disposed at the center of the inner cavity of the baffle pot and is connected to a guide post. A transverse box is added to the corresponding portion of the inner cavity of the baffle pot. A limit plate is added to one side of the inner cavity of the transverse box and is connected to the transverse box. A compression spring is connected to the inner side of the limit plate. The heated liquid is transported to the interior of the upper heat exchange tube via a delivery conduit for flow. A liquid inlet pump transports cooling water from the lower inner cavity of the outer shell to the upper inner cavity of the outer shell, where it contacts the upper heat exchange tube and the baffle pot. When the liquid enters the baffle pot and impacts the baffle, the guide post drives the limit plate to move along the inner cavity of the transverse box and compresses the compression spring, allowing the liquid to flow through the baffle. On the one hand, the structure of the upper heat exchange tube, the baffle pot, and the inner portion of the transverse box greatly reduces the flow rate of the liquid and increases the liquid retention time, thereby allowing the heated liquid to fully contact the cooling water and undergo a cooling treatment. On the other hand, the design of this structure is simple and easy to operate.

[0009] Preferably, the inlet pump is mounted at the lower front and rear ends of one side of the outer shell, and the drainage pump is mounted at the center of the front and rear ends of the other side of the outer shell. The inlet pump and drainage pump are respectively connected to the upper and lower portions of the inner cavity of the outer shell. The inlet pump and drainage pump can be used to replace the cooling water in the upper and lower portions of the inner cavity of the outer shell, thereby preventing the cooling effect of the liquid flowing in the upper heat exchange tube from being reduced after absorbing a certain amount of heat.

[0010] Preferably, the horizontal box is cylindrical in shape, and the top and bottom of the horizontal box are both provided with connecting side plates at the front and rear ends thereof, and connected to the inner wall of the choke pot. The horizontal box is fixed to the inner cavity of the choke pot via the connecting side plates.

[0011] Preferably, an air cooler is installed at the corresponding lower portion of the back of the outer shell, and the air cooler is square in design and tightly connected to the back of the outer shell. The air cooler can draw in external air from the outer shell, cool it down, and then transport it to the corresponding structure.

[0012] Preferably, a lower heat exchange tube is provided in the lower portion of the inner cavity of the outer shell, and the lower heat exchange tube is designed as an S-shape and is divided into three groups, with adjacent lower heat exchange tubes interconnected. The lower heat exchange tube can perform heat exchange operations on the cooling water re-delivered from the lower portion of the inner cavity of the outer shell.

[0013] Preferably, both ends of the lower heat exchange tube extend outward through the inner wall of the outer shell, and the inlet end of the lower heat exchange tube is connected to the air cooler, and the outlet end of the lower heat exchange tube is connected to a dust filter. When the air cooler delivers cold air into the lower heat exchange tube, the lower heat exchange tube is located slightly above the center of the lower inner cavity of the outer shell, thereby effectively heating the returning cooling water.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The cooling water circulation system for the production of quick-setting agent transports the heated liquid to the interior of the upper heat exchange tube through a delivery conduit for flow. The liquid inlet pump transports the cooling water from the lower part of the inner cavity of the outer shell to the upper part of the inner cavity of the outer shell, and contacts the upper heat exchange tube and the baffle. When the liquid enters the baffle and flows and impacts the baffle, the guide column drives the limit plate to move along the inner cavity of the cross box and squeezes the extrusion spring, so that the liquid flows through the baffle. Using this method, on the one hand, the flow rate of the liquid can be greatly reduced and the retention time of the liquid can be increased through the structure inside the upper heat exchange tube, the baffle and the cross box, so that the heated liquid can be fully contacted with the cooling water and cooled. On the other hand, compared with the traditional integrated spiral tube structure, this structure has a strong pressure bearing capacity, and the components are connected in a split manner, which is convenient for disassembly and cleaning. The distance between the infusion pipelines is larger, avoiding heat loss caused by transfer. BRIEF DESCRIPTION OF THE DRAWINGS

A horizontal box 11 is added to the corresponding position of the inner cavity of the baffle pot 8. A limit plate 13 is added to one side of the inner cavity of the horizontal box 11 and is connected to the horizontal box 11. The inner side of the limit plate 13 is connected to an extrusion spring 14.
