Description

Technical Field

[0001] The present invention relates to the technical field of steam generators, and in particular to a steam generator and a use method thereof. Background Art

[0002] A steam generator, also called a steam heat source machine, is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam. The steam generated can be used in various fields such as industrial production, clothing preparation, and food processing. For example, the existing public document CN102498344B-Steam Generator and the existing public document CN106247299B-Steam Generator both disclose a steam generator. Although the existing steam generator can heat water to generate steam, which is convenient for people to use, the existing steam generator still has the following deficiencies in actual use:

[0003] 1. When the existing steam generator performs heat exchange, water is mainly circulated through the serpentine tube to increase the water circulation distance. Fuel is burned outside the serpentine tube to achieve heating and steam generation. However, because the water contains certain minerals, the inside of the serpentine tube will be fouled after long-term use. On the one hand, it is inconvenient for the staff to clean it. On the other hand, the accumulation of dirt will also reduce the efficiency of heat conduction, indirectly causing energy waste;

[0004] 2. When the existing steam generator is in use, the fixed length of the serpentine tube results in a fixed heat exchange energy. When faced with different factors (external temperature, water temperature, fuel composition, etc.), in order to maintain the heat exchange efficiency, either the water flow rate is changed or the unit combustion amount of the fuel is increased. The actual change scheme will affect the final steam generation effect, and changing the length of the serpentine tube will increase the overall space of the steam generator, reducing practicality.

[0005] Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems. Summary of the invention

[0006] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0007] In view of the problem that the dirt inside the serpentine tube of the above-mentioned existing steam generator is inconvenient to clean, thereby reducing the heat conduction efficiency, a steam generator is proposed.

[0008] To solve the above technical problems, the present invention provides the following technical solutions: a steam generator, comprising a combustion mechanism, including an exchange component, an end plate, a spiral blade and a matching rod, the two end plates are symmetrically arranged in a vertical direction, and a plurality of exchange components are arranged in an array in the vertical direction between the two end plates, the exchange component comprises an outer sleeve, two linkage sleeves and two exchange disks, and the outer sleeve, the linkage sleeve and the exchange disk are coaxially arranged from the outside to the inside, n flow grooves are provided in a circumferential array on both end surfaces of the exchange disk, and the n flow grooves at both ends of the exchange disk are arranged in a one-to-one correspondence, the flow grooves are arc-shaped, and n≥2, the flow grooves aligned at both ends of the exchange disk are connected through flow holes arranged at one end of the flow grooves, and when the flow grooves on the two exchange disks in the same exchange component are in an aligned state, the flow holes on the two exchange disks are arranged at both ends of the flow groove on the same horizontal plane; an external thread is provided on the outer wall of the exchange disk, and the inner walls of the two linkage sleeves are provided with holes respectively connected to the outer threads on the two exchange disks. An internal thread with spiral thread matching, wherein a limit ring is fixedly provided on one end face of a linkage sleeve in the circumferential direction, and a limit groove for gap matching of the limit ring is provided on one end face of the other linkage sleeve, a first retaining ring is fixedly provided on one end of the inner wall of the outer sleeve in the circumferential direction, and a first plug column is fixedly provided on one end face of the first retaining ring in a circumferential array, and a first plug hole for slidingly inserting the first plug column is provided on the other end face of the linkage sleeve with the limit groove; flange plates are symmetrically fixedly provided on both ends of the outer wall of the outer sleeve, and the four corner positions of the two flange plates are fixedly connected by fixing sleeves, the fixing holes in the fixing sleeves pass through the two flange plates, and the coaxial fixing holes in multiple exchange components are slidably sleeved on the same matching rod, and a locking nut is spirally matched on the free end of the matching rod; a waste heat utilization mechanism arranged on one side of the combustion mechanism includes a treatment box and a serpentine pipe arranged inside the treatment box; and a connecting mechanism for connecting the combustion mechanism and the waste heat utilization mechanism includes a gas pipe, a water pipe and a cross plate.

[0009] The beneficial effects of the present invention are as follows: with the design of the steam generator, when the staff loosens the locking nut and removes the matching rod from the exchange assembly and the end plate, the multiple exchange assemblies are in a separated state. Because of the spiral matching arrangement between the exchange disk and the linkage sleeve, the two exchange disks in the separated exchange assembly can be twisted and separated. At this time, the flow slot for water circulation is in an exposed state, and the staff can easily clean the dirt in the flow slot. This design method is convenient to operate as a whole and has a long service life.

[0010] In addition, multiple switching components are stacked and fixed, so when a single switching component is damaged, the staff can also replace it well, and the replacement cost is low, and the overall practicality is good.

[0011] As a preferred solution of a steam generator of the present invention, the cross-section of the limiting ring is T-shaped, and a first oil seal groove is circumferentially provided on the upper surface of the free end of the limiting ring; third ring grooves are circumferentially provided on the side walls adjacent to each other of the two exchange disks, and the two third ring grooves are filled with extension rings, and the outer side wall of the extension ring is fixedly connected to the inner wall of one of the linkage sleeves; a second ring groove for the clearance fit of the first retaining ring is circumferentially provided on one end surface of one of the linkage sleeves.

[0013] As a preferred embodiment of a steam generator of the present invention, a combustion groove is provided in the middle of the exchange disk, the combustion grooves in the multiple exchange components constitute a combustion chamber, spiral blades are arranged in the combustion chamber, and the outer wall of the spiral blades is in contact with the inner wall of the combustion groove; an air groove connected to the combustion chamber is provided in the middle of the end plate, a second retaining ring is fixedly provided on the inner wall of the air groove, and a second plug-in column is fixedly provided on one end face of the second retaining ring along a circumferential array, linkage rings are fixedly provided at both ends of the spiral blade, the linkage rings are in contact with one side face of the second retaining ring, and a second plug-in hole for slidingly inserting the second plug-in column is provided on the linkage ring; a first air connecting pipe is fixedly provided on the outer side of the air groove on the side face of the end plate away from the exchange component, and an igniter is installed on the first air connecting pipe located below.

[0014] As a preferred solution of a steam generator of the present invention, a concave cavity is opened on one side of the end plate close to the exchange component, and the concave cavity is covered on the outside of the circulation groove on the same horizontal plane, and a first water connecting pipe connected to the concave cavity is fixedly provided on the side of the end plate away from the exchange component.

[0015] As a preferred solution of a steam generator of the present invention, a third sealing ring coaxial with the concave cavity is fixedly provided on the end plates on both sides inside and outside the concave cavity, and a third oil seal groove is circumferentially opened on the free end of the third sealing ring, and a first sealing groove for gap fitting of the third sealing ring is opened on one side of an exchange disk adjacent to the end plate; a second sealing ring gap fitting with the first ring groove is fixedly provided on one side of one of the end plates, and fourth oil seal grooves are circumferentially opened on the inner and outer walls of the second sealing ring, and a second sealing groove for gap fitting of the first sealing ring is opened on one side of the other end plate.

[0016] In view of the fact that the existing steam generators cannot make good adjustments to maintain the steam generation effect in response to the influence of different factors, a steam generator of the present invention is further preferably improved, wherein: the combustion mechanism also includes a driving assembly, and the driving assembly is arranged on one side of the exchange assembly, the driving assembly includes a gear plate and a U-shaped plate, and a ring tooth is fixedly sleeved on the outer wall of one linkage sleeve, and the ring tooth gap fits in the first ring groove, and an arc-shaped through groove connected to the first ring groove is also provided in the outer sleeve, and part of the gear plate passes through the arc-shaped through groove and engages with the ring tooth, and multiple gear plates are fixedly sleeved on the same rotating rod, and the two ends of the rotating rod are respectively rotatably connected to the two ends of the U-shaped plate through rolling bearings, one end of the rotating rod passes through the U-shaped plate and is embedded in the output end of the motor, and the motor is fixedly connected to the U-shaped plate, the open end of the U-shaped plate is close to one side of the exchange assembly, and the two ends of the U-shaped plate are respectively fixedly connected to the two end plates.

[0017] Another beneficial effect of the present invention is that when the steam generator is in use, the operation of the motor can realize the rotation of multiple gear plates driven by the rotating rod. Because the meshing setting between the gear plate and the ring gear can realize the ring gear driving the linkage sleeve to rotate, and then driving the exchange plate spirally fitted thereon to rotate. Because the two linkage sleeves in the same exchange component are in a limited state and an active state, when one of the exchange plates is driven to rotate, the flow grooves on the two exchange plates that were originally in an overlapping state are in a dislocated state. The greater the degree of dislocation, the greater the distance between the flow holes on the two flow grooves, thereby increasing the flow distance of water in the same exchange component. This design method can be adjusted according to actual conditions, so that effective steam generation under different factors can be met, and the overall space will not be increased during adjustment, which has good practicality.

[0020] In addition, the present invention also provides the following technical solution: a method for using a steam generator, wherein the steam generator is operated and used according to the following steps;

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example 1

[0043] Reference Figure 1 , Figure 2 and Figure 3, which is the first embodiment of the present invention, provides a steam generator.

[0044] Specifically, it includes a combustion mechanism 100, including an exchange component 101, an end plate 102, a spiral blade 104 and a matching rod 105, the two end plates 102 are symmetrically arranged in the vertical direction, and a plurality of exchange components 101 are arranged in an array in the vertical direction between the two end plates 102; a waste heat utilization mechanism 200 arranged on one side of the combustion mechanism 100, including a treatment box 201 and a serpentine tube 202 arranged inside the treatment box 201; and a connecting mechanism 300 for connecting the combustion mechanism 100 and the waste heat utilization mechanism 200, including a gas pipe 301, a water pipe 302 and a cross plate 303.

[0045] See Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the exchange component 101 includes an outer sheath 101a, two linkage sleeves 101b and two exchange disks 101c, and the outer sheath 101a, the linkage sleeve 101b and the exchange disk 101c are coaxially arranged from the outside to the inside, and n flow grooves 101c-2 are arranged in a circumferential array on both end faces of the exchange disk 101c, and the n flow grooves 101c-2 at both ends of the exchange disk 101c are arranged one by one, and the flow grooves 101c-2 are arc-shaped, and n≥2. The flow grooves 101c-2 at both ends of the exchange disk 101c are aligned and connected through a flow hole 101c-3 arranged at one end of the flow groove 101c-2, as shown in FIG. Fig. 9 As shown in state I, when the flow slots 101c-2 on the two exchange disks 101c in the same exchange assembly 101 are aligned, the flow holes 101c-3 on the two exchange disks 101c are arranged at both ends of the flow slot 101c-2 on the same horizontal plane;

[0046] When the above arrangement is used, the aligned flow slots 101c-2 at both ends of the same exchange disk 101c are used to realize water flow through the flow holes 101c-3, and the water between two adjacent exchange disks 101c flows through the flow slots 101c-2. In this way, when the two exchange disks 101c are in a misaligned state, the water flow distance can be increased. Fig. 9 As shown in the II state.

On the one hand, it is convenient to clean the dirt in the flow groove 101c-2 in the exchange disk 101c, and on the other hand, it is convenient to disassemble and replace the exchange disk 101c. A limiting ring 101b-7 is fixedly provided on one end face of one of the linkage sleeves 101b in the circumferential direction, and a limiting groove 101b-5 for clearance matching of the limiting ring 101b-7 is provided on one end face of the other linkage sleeve 101b, so that the two linkage sleeves 101b can be in a state of relative rotation.

This arrangement can realize that one of the two linkage sleeves 101b in the same exchange component 101 is in a positioning state, and a second annular groove 101b-1 for clearance fit of the first butt ring 101e is circumferentially provided on one end face of one of the linkage sleeves 101b, thereby improving the tightness of fit of adjacent exchange components 101;

[0048] When the above arrangement is in use, one of the linkage sleeves 101b is in a positioning state relative to the first retaining ring 101e, so that the other linkage sleeve 101b can be in a rotating state, indirectly driving one of the exchange disks 101c to rotate relative to the other exchange disk 101c, thereby facilitating the relative position adjustment of the flow slots 101c-2 on the adjacent exchange disks 101c.

[0049] Furthermore, third annular grooves 101c-4 are circumferentially provided on the adjacent side walls of the two exchange disks 101c, and the two third annular grooves 101c-4 are filled with extension rings 101b-4, and the outer side walls of the extension rings 101b-4 are fixedly connected to the inner wall of one of the linkage sleeves 101b, thereby improving the coordination and limiting function between the exchange disk 101c and the linkage sleeve 101b and indirectly playing a certain sealing role.

[0050] See Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig.10As shown, flange plates 101a-1 are symmetrically fixed at both ends of the outer wall of the outer sheath 101a, and the four corner positions of the two flange plates 101a-1 are fixedly connected by fixing sleeves 101a-2.

The coaxially arranged fixing holes 101a-3 in multiple exchange components 101 are slidably sleeved on the same matching rod 105, and a locking nut 105a is spirally fitted on the free end of the matching rod 105. This arrangement can realize a detachable connection between multiple exchange components 101. Of course, in actual use, the two end plates 102 should also be fixed to the flange plates 101a-1 through the matching rods 105.

[0051] Of course, in actual use, a sealing ring can be added between the adjacent flange plates 101a-1 of two adjacent outer sheaths 101a when they are matched to improve the sealing performance of the match.

[0052] Furthermore, a first sealing ring 101d is circumferentially provided at one end of the outer sheath 101a, and a second oil seal groove 101d-1 is circumferentially provided on the inner and outer side walls of the first sealing ring 101d, and the second oil seal groove 101d-1 is filled with high-temperature resistant waterproof sealing oil; a first annular groove 101a-5 is circumferentially provided on the other end surface of the outer sheath 101a provided with the first sealing ring 101d, and the first sealing ring 101d and the first annular groove 101a-5 are gap-fitted between the two adjacent outer sheaths 101a, so that the sealing performance between the two adjacent outer sheaths 101a can be achieved. Example 2

[0053] Reference Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig.11 , which is the second embodiment of the present invention, is based on the previous embodiment, but is different in that this embodiment is proposed in order to improve the completeness of combustion and the effectiveness of heat exchange.

[0057] When the above arrangement is in use, the gas enters from the first gas connecting pipe 102a at the lower end of the combustion mechanism 100, the entered gas is ignited by the igniter 102a-1, and the gas burns in the combustion chamber. The setting of the spiral blades 104 will produce a guiding effect when the gas enters the combustion chamber. Under the action of the centrifugal force of the gas, the gas will flow along the inner wall of the combustion chamber, so that the fuel combustion can be made closer to the inner wall of the combustion chamber, thereby improving the heat exchange rate.

[0058] Furthermore, a concave cavity 102d is provided on one side of the end plate 102 close to the exchange component 101, and the concave cavity 102d covers the outer side of the circulation groove 101c-2 on the same horizontal plane, and a first water connecting pipe 102b connected to the concave cavity 102d is fixedly provided on one side of the end plate 102 away from the exchange component 101, so that water in the circulation groove 101c-2 can enter the concave cavity 102d and then circulate through the first water connecting pipe 102b, so that water can circulate inside and outside the combustion mechanism 100;
