This utility model provides a cage injection mold with a rapid preheating structure, comprising: a moving mold at the bottom of a fixed mold; a sprue sleeve passing through the center of the fixed mold on the side away from the moving mold; a mold core assembly positioned at the center of the fixed mold and the moving mold on the side close to each other; a hot runner heating module sleeved on the bottom of the sprue sleeve at the top; and a heating rod heating module passing through the center of the mold core assembly; and several junction boxes bolted to the side walls of the fixed mold and the moving mold. In the mold preheating process, based on heat conduction heating using a mold temperature controller, a hot runner heating module and a heating rod heating module are installed at the core of the mold. These are connected to a power plug via junction boxes to achieve electric heating at the core, which assists in rapid mold preheating and greatly improves processing efficiency. During injection, the temperature of the liquid plastic does not drop when it enters the molding cavity composed of the fixed mold core and the moving mold core, improving the quality of the injection molded parts. Furthermore, the injection runner can be diverted to allow one mold to process multiple injection molded parts simultaneously, improving production efficiency.

Disclosed is a substrate processing apparatus including: a heating unit including a heating plate for supporting and heating a substrate; and a pressure reduction unit for applying a vacuum pressure to a space between a top surface of the heating plate and the substrate supported on the heating plate, in which the heating plate is provided with a lifting hole that is a movement channel for a lifting pin to lift the substrate supported on the heating plate, and the top end of the lifting hole is arranged at a position higher than the top surface of the heating plate.

The invention discloses a dry quenching diffused gas desulfurization system. The system comprises a desulfurizer, a dust remover, a booster fan and a chimney which are sequentially communicated through a pipeline, an inlet of the desulfurizer is communicated with a dry quenching diffused gas inlet pipeline, and an inlet SO2 concentration measuring instrument and inlet flue gas flow detection equipment are arranged on the dry quenching diffused gas inlet pipeline; at least one feeding position is arranged in the desulfurizer along the flowing direction of fluid, a spray head for spraying a desulfurizing agent is arranged on the feeding position, and the spray head is communicated with an external desulfurizing agent supply pipeline; and an SO2 concentration measuring instrument is arranged in the chimney. The invention also discloses a dry quenching diffused gas desulfurization method. The desulfurization device has the beneficial effects that the desulfurizer is provided with at least one feeding position, the feeding amount of a desulfurizing agent is adjusted for desulfurization according to the flow of the dry quenching diffused gas and the concentration of SO2, the temperature of the dry quenching diffused gas is not reduced and the air volume of the system is not increased during desulfurization, and the subsequent waste heat recovery is not influenced.

A glue tank for a glass fiber reinforced plastic pipeline winding machine relates to the technical field of glass fiber reinforced plastic pipeline production and comprises a tank body, a glue scraping plate is arranged on one side of the top of the tank body and driven by a power mechanism to reciprocate in the tank body, a glue collecting tank is formed in the middle of the tank body, and the tank bottom of the glue collecting tank is obliquely arranged. According to the glue scraping device, the groove body, the glue scraping plate and the glue collecting groove are arranged, glue in the groove body is scraped into the glue collecting groove by driving the glue scraping plate to do reciprocating motion through the power mechanism, and the glue flows into the glue receiving barrel through the glue outlet in the low-position end of the glue collecting groove to be recycled in a unified mode. The recovery efficiency is improved, and the production cost is reduced.

The utility model discloses a constant temperature beehive relates to constant temperature beehive technical field, including the beehive, one side inner wall of the beehive is provided with a plurality of mounting frame, the inner side of mounting frame is fixedly connected with the auxiliary plate, one side of the beehive is fixedly connected with the feeding box, the inner wall of the feeding box is fixedly connected with the material guide box, and the material guide box is fixedly connected with the feeding box. The top of the inner wall of the feeding box is rotationally connected with a first heat preservation plate and a second heat preservation plate, and the bottom of the second heat preservation plate is rotationally connected with a connecting strip. According to the constant-temperature beehive, one end of a sweet water box is located at the bottom of a material guiding box, sweet water is added into a feeding box and flows into the sweet water box through the material guiding box, then a second heat preservation plate is closed, a push rod and the sweet water box are pushed back to the original positions through a handle and a limiting disc, and then the sweet water box is heated to the original position. Honeybee shells stay on the upper surfaces of the isolation plates, so that the honeybees can eat the sweet water, and the effects that the honeybees can be fed with the sweet water without opening the top plate and the temperature in the beehive is not reduced are achieved.
