Description

Technical Field

[0001] This utility model belongs to the technical field of casting equipment modification in the manufacturing process of instrument transformers, and specifically relates to a casting nozzle decomposer for casting equipment. Background Technology

[0002] The manufacturing process of instrument transformers requires the use of large amounts of epoxy resin for vacuum casting. Epoxy resin, a new type of insulating material developed in the 1950s, is widely used in the manufacture of power transmission and transformation equipment. The vacuum casting process allows for easier removal of air bubbles from the epoxy resin casting material, significantly improving both the internal and external quality of the finished product, thus driving the development of power transmission and transformation technology. However, due to the complex shape of the product and the complex or unreasonable design of the mold structure, dead zones or narrow venting channels may occur, preventing the timely removal of air from the mold before or during casting, resulting in porosity. Under high voltage conditions, porosity alters the local electric field distribution, affecting the partial discharge and causing bubble breakdown, thereby increasing production costs and reducing product yield. Furthermore, the casting equipment uses only one casting nozzle, requiring individual casting, which is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0003] To address at least one technical problem existing in the prior art, a pouring nozzle decomposer for a pouring equipment is provided. This device can directly decompose the pouring nozzle into multiple smaller pouring nozzles. The flexible pouring nozzle can extend to the bottom of the current transformer mold, avoiding or reducing the impact of dead corners and narrow exhaust channels, thereby improving the product qualification rate. At the same time, multiple pouring nozzles can pour simultaneously, thereby improving product production efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a casting nozzle decomposer for a casting equipment, characterized in that, according to the material flow sequence, the material flows sequentially through a mixing tank, a feed inlet, a three-way connector, a liquid distribution pipe, a discharge outlet, and a flexible hose casting nozzle before reaching the bottom of the mold; the feed inlet is connected to the original casting nozzle of the casting tank; the three-way connector is connected to the feed inlet for diverting the resin material; the liquid distribution pipe is connected to the outlet of the three-way connector for further diverting the resin material to multiple discharge outlets; the multiple discharge outlets... The material inlet is located at the lower end of the liquid distribution pipe; a pneumatic valve is located at each outlet to control the discharge and stop of resin material; the flexible pouring nozzle is connected to the lower end of each pneumatic valve to guide the resin material to the bottom of the mold; the air inlet pipe and air outlet pipe are respectively connected to each pneumatic valve to input and output gas to control the opening and closing of the pneumatic valve; the regulating valve is located outside the pouring tank and connected to the air inlet pipe and air outlet pipe to regulate the air source to control the opening size of the pneumatic valve, thereby regulating the flow rate and flow volume of the resin material.

[0005] Preferably, the liquid distribution pipe is made of stainless steel and its structure includes more than one branch pipe, each branch pipe corresponding to a discharge port.

[0006] Preferably, the flexible pouring nozzle is a flexible hose with an adjustable length, which can be directly inserted into the bottom of the mold for pouring.

[0007] Preferably, the pneumatic valve is opened and closed by a pneumatic power source, and the regulating valve can independently control the opening size of each pneumatic valve.

[0008] Preferably, the hose pouring nozzle is also used as a cleaning pipe when cleaning equipment, through which cleaning waste liquid is discharged.

[0009] Preferably, the casting tank is provided with an observation window for observing the flow of resin material.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides a decomposer for a casting equipment, which has good stability, strong practicality, and high efficiency. It can effectively regulate the flow rate and volume of epoxy resin, enabling the casting of multiple instrument transformer products simultaneously. By setting a stainless steel tee connector, the original casting nozzle of the equipment can be directly replaced, leading the resin material into the decomposer pipeline to achieve resin material diversion. By setting a pneumatic valve, the pneumatic principle can be used to open and close the pneumatic valve to achieve the supply and interruption of resin material. By setting a flexible hose casting nozzle, the resin material can be led to the bottom of the product mold, avoiding or reducing the phenomenon of dead corners and narrow exhaust channels. By setting a cleaning hose, the decomposer pipeline can be cleaned regularly and cleaning waste liquid can be discharged in a timely manner. By setting a valve, the flow rate and volume of the resin material, as well as the opening and closing of the pneumatic valve, can be controlled from the outside of the equipment.

[0019] In actual use, the product mold 11 (based on the size of the casting tank 1 and the number of products to be cast) is placed neatly inside the casting tank 1. The flexible hose casting nozzle 7 is inserted into the bottom of the mold 11, avoiding the product coil. The door of the casting tank 1 is closed, and a vacuum process is performed. After the vacuum process is completed, casting begins.

The regulating valve 10 is adjusted, and the air source is input and output through the air inlet pipe 8 and the air outlet pipe 9. The opening size of the pneumatic valve 6 is adjusted by changing the strength of the air source. The flow rate and flow of the resin material are observed. Once the process control requirements are met, the second regulating valve 10 is opened, and the operation is repeated. Multiple products can be cast simultaneously, saving casting time and improving production efficiency.
