Description

Technical Field

[0001] This utility model relates to the technical field of steam condensate recovery devices, and in particular to a steam condensate recovery device. Background Technology

[0002] Condensate: refers to liquid water formed by the condensation process of water vapor (i.e., gaseous water). In the operation of some heat exchange and heating equipment such as plate heat exchangers and boilers, a large amount of steam is generated. In order to utilize the steam condensate, it is necessary to use a recovery device to recover the steam condensate.

[0003] Patent document CN205980835U discloses a steam condensation recovery device, including a vertical recovery tank. Inside the tank, from top to bottom, are arranged a first partition, a second partition, and a third partition, dividing the tank into a steam chamber, a condensation chamber, a negative pressure collection chamber, and a storage chamber, distributed from top to bottom. The negative pressure collection chamber is connected to a vacuum pump via a protective tank. A steam inlet is located at the top of the steam chamber. The condensation chamber, the negative pressure collection chamber, and the storage chamber are connected by a connecting pipe equipped with a switch valve. This invention can recover and reuse waste low-pressure steam generated in dyeing and printing workshops, making it more energy-efficient and environmentally friendly.

[0004] The above solution involves supplying cold water into the condensing chamber to condense the steam in the steam pipe into water. However, this solution lacks a mechanism for recycling the cold water, which requires an external water supply device to continuously supply water into the condensing chamber through the inlet, resulting in water waste. In addition, the recovery tank in this solution is a one-piece welded structure, which makes it inconvenient to clean the scale in the condensing chamber later. Summary of the Invention

[0005] This utility model discloses a steam condensate recovery device, which aims to solve the technical problem that existing steam condensate recovery devices cannot perform circulating water heat exchange, resulting in water waste.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A steam condensate recovery device includes a tank and a top cover. A connecting mechanism is provided between the top cover and the tank. A base is installed at the lower end of the tank, and a transfer mechanism is provided on the lower surface of the base.

[0008] A partition is fixedly installed on the inner wall of the tank, and the interior of the tank is divided into a condensation chamber and a collection chamber by the partition. An installation opening is opened through the surface of the partition. A spiral condenser tube is embedded on the upper surface of the top cover. The lower end of the spiral condenser tube extends into the interior of the collection chamber through the installation opening. A negative pressure pump is fixedly installed on the left side surface of the tank, and the suction end of the negative pressure pump extends into the interior of the collection chamber.

[0009] A water storage tank and a circulating water pump are fixedly installed on the front and back of the tank, respectively. The outlet end of the circulating water pump extends into the interior of the condensation chamber, and the pumping end of the circulating water pump is connected to the interior of the water storage tank. A return pipe is embedded on the upper surface of the water storage tank, and a connection port is opened on the surface of the top cover. The end of the return pipe away from the water storage tank is threadedly connected to the inner wall of the connection port. A semiconductor cooler is embedded on the front of the water storage tank, and the cooling end of the semiconductor cooler extends into the interior of the water storage tank. A water outlet pipe is embedded on the inner wall of the right side of the collection chamber, and an electric valve is installed on the surface of the water outlet pipe.

[0010] In a preferred embodiment, the connecting mechanism includes a mounting bottom edge and a mounting top edge, which are respectively fixedly installed on the surfaces of the tank body and the top cover. An annular insert plate is fixedly installed on the lower surface of the mounting top edge, and an annular slot adapted to the annular insert plate is opened on the upper surface of the mounting bottom edge. Limiting grooves are opened on both inner walls of the annular slot. Sliding openings penetrating into the limiting grooves are opened on both inner surfaces of the mounting bottom edge. Pull rings are slidably connected to the inner walls of the sliding openings. A limiting tooth block is fixedly connected to one end of the pull ring located inside the limiting groove. An annular tooth groove adapted to the limiting tooth block is opened on the surface of the annular insert plate. A spring is sleeved on the surface of the pull ring, and the two ends of the spring are fixedly connected to the inner wall of the limiting groove and the surface of the limiting tooth block, respectively.

[0011] By using limiting teeth and annular inserts, the top cover can be securely closed to the tank body.

[0012] In a preferred embodiment, a sealing plate is fixedly installed on the lower end surface of the spiral condenser, and sealing gaskets are embedded in both the lower surface of the sealing plate and the upper surface of the mounting bottom edge.

[0013] By using sealing gaskets, the sealing effect after the top cover and tank body are closed can be improved.

[0014] In a preferred embodiment, the spiral condenser is made of copper, a metal material known for its excellent thermal conductivity.

[0015] In a preferred embodiment, the transfer mechanism includes a storage groove formed on the lower surface of the base. A threaded rod is rotatably connected to the inner top wall of the storage groove. A rotating opening extending through the storage groove is formed on the left side surface of the base. A crank handle is rotatably connected to the inner wall of the rotating opening. A bevel gear is fixedly connected to both the end of the crank handle located inside the storage groove and the surface of the threaded rod. A mounting plate is threadedly connected to the surface of the threaded rod. Four universal wheels arranged in a circumferential array are mounted on the lower surface of the mounting plate.

[0016] The omnidirectional wheels facilitate the transportation of this device.

[0017] In a preferred embodiment, guide sliders are provided on both sides of the mounting plate, and guide grooves for the guide sliders to slide are provided on both sides of the inner wall of the storage groove.

[0018] By setting a guide slider, the mounting plate can move up and down in a directional manner by rotating the threaded rod and driving the caster wheel through the guide slider's rotation.

[0019] As can be seen from the above, the steam condensate recovery device provided by this utility model has the following technical effects.

[0020] Firstly, the operation of the negative pressure pump creates a negative pressure in the collection chamber. Under this negative pressure, the spiral condenser tube draws steam into the collection chamber and discharges it through the negative pressure pump. During this process, the operation of the circulating water pump draws water from the storage tank into the condensation chamber and returns it to the storage tank through the return pipe. This cycle continues. As the water flows through the condensation chamber, it exchanges heat with the steam in the spiral condenser tube, turning it into condensate. The condensate then falls into the collection chamber through the spiral condenser tube for collection, thus achieving the purpose of recovering steam condensate. This method achieves both water circulation and heat exchange, resulting in good condensation performance.

[0021] Secondly: Pulling the pull ring causes the limiting tooth block to retract into the limiting groove, separating the limiting tooth block from the annular groove of the annular insert plate. Without the limitation of the limiting tooth block, lifting the top cover will pull the spiral condenser tube out of the condensation chamber. During assembly, align the lower end of the spiral condenser tube with the installation opening on the surface of the partition plate, and close the top cover and the tank body. Insert the annular insert plate on the lower surface of the top cover into the annular slot on the surface of the tank body. During this process, the limiting tooth block is pushed into the annular groove of the annular insert plate by the action of the spring to lock together, so that the top cover and the tank body are tightly closed together, thus completing the installation work and providing convenience for its loading and unloading.

[0022] Thirdly, when it is necessary to move or adjust the installation position of the device, turn the crank to drive the threaded rod to rotate through the bevel gear. Under the guidance of the guide slider, the mounting plate can drive the caster to move down through the rotation of the threaded rod until the caster lifts and supports the tank. At this time, the device can be moved by the caster, which facilitates its transportation. Attached Figure Description

[0033] The collection chamber 6 is equipped with a liquid level sensor. When the liquid level in the collection chamber 6 reaches a certain level, the electric valve opens to discharge the condensate in the collection chamber 6. The temperature of the water in the water storage tank 9 can be reduced by the semiconductor cooler 12.

An annular insert plate 16 is fixedly installed on the lower surface of the mounting top edge 15. An annular slot adapted to the annular insert plate 16 is opened on the upper surface of the mounting bottom edge 14. Limiting grooves are opened on both sides of the inner wall of the annular slot. Sliding openings penetrating into the limiting grooves are opened on both sides of the mounting bottom edge 14. A pull ring 17 is slidably connected to the inner wall of the sliding opening.

The two ends of the spring 19 are fixedly connected to the inner wall of the limiting groove and the surface of the limiting tooth block 18, respectively.

[0035] By setting the limiting tooth block 18 and the annular insert plate 16, the top cover 2 and the tank body 1 can be tightly closed together.

[0036] A sealing plate 20 is fixedly installed on the lower end surface of the spiral condenser 7. Both the lower surface of the sealing plate 20 and the upper surface of the mounting bottom edge 14 are fitted with sealing gaskets 21. By setting the sealing gaskets 21, the sealing effect after the top cover 2 and the tank body 1 are closed can be improved.

[0037] Reference Figure 2 and Figure 4 In a preferred embodiment, the transfer mechanism includes a storage groove formed on the lower surface of the base 3.

[0038] Guide sliders are provided on both sides of the mounting plate 25, and guide grooves are provided on both sides of the inner wall of the storage groove for the guide sliders to slide. Under the guidance of the guide sliders, the mounting plate 25 can drive the caster 26 to move up and down in a directional manner through the rotation of the threaded rod 22.

[0039] Working principle: During use, connect the upper end of the spiral condenser tube 7 to the steam discharge end of the external equipment. At this time, the negative pressure pump 8 operates to create a negative pressure in the collection chamber 6. Under negative pressure, the spiral condenser tube 7 draws steam into the collection chamber 6 and discharges it through the negative pressure pump 8. During this period, the circulating water pump 10 draws water from the water storage tank 9 into the condensing chamber 5 and returns it to the water storage tank 9 through the return pipe 11. This cycle continues. When the water flows through the condensing chamber 5, it can exchange heat with the steam in the spiral condenser tube 7, turning it into condensate. The condensate then falls into the collection chamber 6 through the spiral condenser tube 7 for collection, thus achieving the purpose of recovering steam condensate. When it is necessary to clean the inside of the condensing chamber 5, pull the pull ring 17 to drive the limiting tooth block 18 into the limiting groove, causing the limiting tooth block 18 to separate from the annular tooth groove of the annular insert plate 16. Without the limitation of the limiting tooth block 18, lifting the top cover 2 will drive the spiral condenser tube 7 to clean the steam. The condenser tube 7 is pulled out from the condenser chamber 5 to facilitate cleaning of the interior of the condenser chamber 5. During assembly, the lower end of the spiral condenser tube 7 is aligned with the installation opening on the surface of the partition plate 4, and the top cover 2 is closed with the tank body 1. The annular insert plate 16 on the lower surface of the top cover 2 is inserted into the annular slot on the surface of the tank body 1. During this process, the limiting tooth block 18 is pushed into the annular tooth groove of the annular insert plate 16 by the action of the spring 19 to engage, so that the top cover 2 and the tank body 1 are tightly closed together, thus completing the installation. When it is necessary to move or adjust the installation position of the device, the crank handle 23 is turned to drive the threaded rod 22 to rotate through the bevel gear 24. Under the guidance of the guide slider, the mounting plate 25 can be driven by the rotation of the threaded rod 22 to move the universal wheel 26 downward until the downward movement of the universal wheel 26 lifts and supports the tank body 1. At this time, the device can be moved by the universal wheel 26, which facilitates its transportation.
