Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for garment production, and more specifically to an optimized device for preheating steam generation and circulating ironing water in garment workshops. Background Technology

[0002] Steam ironing is an important part of garment production. Its function is to use the heat and humidity of steam to shape, remove wrinkles and finish garment fabrics and parts, ensuring that the finished garments are neat in shape, flat in appearance and meet process standards.

[0003] However, energy waste is a common problem in the operation of traditional steam production systems. For example, the condensate return water from steam irons retains residual heat, causing the steam ironing platform that collects it in the workshop to dissipate heat outward, which raises the workshop temperature and deteriorates the working environment. Moreover, this residual heat is wasted due to the lack of targeted recovery devices. At the same time, the makeup water for steam generating equipment needs to be heated directly from room temperature to boiling point, which not only consumes a lot of extra energy but also prolongs the steam generation time, resulting in high unit steam production energy consumption costs and failing to meet the industry's demand for energy recycling. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned defects in the prior art and provide an optimized steam generation device for ironing water circulation and preheating in garment workshops. It aims to efficiently recover and utilize steam process return water, reduce the energy consumption of steam generation equipment for heating makeup water, shorten the steam generation time, reduce the energy consumption cost per unit of steam production, and ultimately achieve a dual improvement in energy recycling and system operating efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a preheating steam generation optimization device for ironing water circulation in a garment workshop, comprising a water tank and an electric steam boiler. The outlet of the water tank is connected to the inlet of the electric steam boiler via an inlet pipe. A main water pump is connected in series on the inlet pipe. The steam outlet of the electric steam boiler is connected to a main steam supply pipe. Several steam branch supply pipes are branched onto the main steam supply pipe. Each steam branch supply pipe is connected to a steam iron. Each steam iron is paired with an ironing workbench. The ironing workbench is characterized by having a water storage chamber inside each ironing workbench. A return water branch pipe is provided next to each water storage chamber. An auxiliary water pump is connected in series on each return water branch pipe. All return water branch pipes converge into a return water manifold, which is connected to the inlet of the water tank.

[0006] In this invention, water in the water tank enters the electric steam boiler through the inlet pipe and the main water pump, where it is heated to generate steam. The steam is then transported to each steam iron through the main steam supply pipe and the steam distribution pipe. The water generated during the ironing process is collected in the water storage chamber of the ironing workbench and returned to the water tank through the auxiliary water pump, the return water branch pipe, and the return water manifold, thus achieving water circulation.

[0007] This invention optimizes and constructs a targeted waste heat recovery device to collect the condensate generated during the operation of a steam iron. Utilizing its residual heat, the condensate is introduced into a water tank and mixed with the makeup water to be heated for heat exchange. This process effectively increases the initial temperature of the makeup water, allowing it to complete the "preheating" stage in advance. When the preheated water enters the steam generating equipment, there is no need to consume a large amount of additional energy to raise the water temperature to the boiling point, thus significantly shortening the steam generation time and reducing the energy consumption cost required for unit steam production. Ultimately, this achieves a dual improvement in energy recycling and system operating efficiency.

[0008] Preferably, a filter box is connected in series on the return water branch pipe between each water storage chamber and the corresponding auxiliary water pump, and a filter screen is provided inside the box cavity of each filter box.

[0009] This invention provides a filter box on the return water branch pipe between each water storage chamber and the auxiliary water pump. The filter screen inside the box can remove impurities from the return water, preventing impurities from entering the water tank and electric steam boiler, thus affecting the normal operation of the equipment and the quality of steam.

[0010] Preferably, a one-way valve is connected in series on the return water manifold, and the one-way valve is directed from each return water branch pipe toward the water tank.

[0011] The one-way valve on the return water manifold of this utility model can prevent water backflow and ensure that the return water can only flow from the return water manifold to the water tank, thus avoiding system failure and water flow disorder.

[0012] Preferably, a pressure stabilizing valve is connected in series on the main steam supply pipe.

[0013] The pressure stabilizing valve on the main steam supply pipe of this invention can maintain stable steam pressure, ensuring that each steam iron receives a uniform and stable steam supply, thereby improving the ironing effect and quality.

[0014] Preferably, a shut-off valve is connected in series on the water inlet pipe and located next to the main water pump.

[0015] The shut-off valve on the side of the main water pump on the inlet pipe of this utility model can close the water inlet channel when needed, which facilitates the maintenance and repair of the equipment. For example, when cleaning the water tank or repairing the electric steam boiler, the shut-off valve can be closed to prevent water leakage.

[0016] Preferably, a water supply pipe is also provided on the water tank, and an automatic water supply valve is connected in series on the water supply pipe.

[0017] The water supply pipe and automatic water supply valve on the water tank of this utility model can automatically replenish water according to the water level in the water tank (if necessary, a water level signal detector can be added) to ensure that the water tank always has a sufficient water supply and to ensure the normal operation of the electric steam boiler.

[0018] Preferably, the upper end of the water tank is also provided with an overflow outlet, which is connected to the inner cavity of the water tank.

[0019] The overflow port at the top of the water tank of this utility model can discharge excess water when the water level in the tank is too high, preventing the water tank from overflowing and protecting the equipment and working environment.

[0020] Preferably, the outer walls of the main steam supply pipe, each steam branch supply pipe, each return water branch pipe, and the return water manifold are all wrapped with heat-insulating cotton pipes.

[0021] The insulation cotton pipe wrapped around the outer layer of the main steam supply pipe, the branch steam supply pipe, the return water branch pipe, and the return water manifold of this utility model can reduce heat loss, improve energy utilization, and at the same time prevent the pipe surface temperature from becoming too high, thus preventing burns to operators.

[0022] Beneficial effects: This utility model efficiently recovers and utilizes steam process return water, reduces the energy consumption of steam generating equipment for heating makeup water, shortens steam generation time, reduces the energy consumption cost per unit of steam production, and ultimately achieves a dual improvement in energy recycling and system operating efficiency.
