Description

Technical Field

[0001] This utility model belongs to the field of steam heating technology, and more specifically, it relates to a steam generator. Background Technology

[0002] In the production processes of trichlorotoluene and chlorinated paraffin, some steps require steam heating, which is generated by a steam generator. One type of steam generator heats water using an electric heating element to produce steam. Existing steam generators cannot filter the water to be heated. Therefore, during operation, impurities in the water adhere to the surface of the electric heating element, forming scale, which reduces heating efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a steam generator that solves the problem that existing steam generators cannot filter the water to be heated.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A steam generator is provided, comprising a water supply container, an annular support, a filter assembly, a water inlet pipe, a steam generating container, an electric heating rod, a water supply pipe, and a water supply pump. The inner side of the water supply container has an annular support protruding inward in a circumferential direction. The filter assembly is located inside the water supply container and placed on the annular support, dividing the water supply container into an inlet chamber above the filter assembly and a storage chamber below the filter assembly. One end of the water inlet pipe is fixedly connected to the water supply container and communicates with the inlet chamber. The top of the steam generating container has a steam outlet. The electric heating rod is fixedly installed inside the steam generating container. One end of the water supply pipe is fixedly connected to the water supply container and communicates with the storage chamber, and the other end is fixedly connected to the steam generating container and communicates with the interior of the steam generating container. The water supply pump is mounted on the water supply pipe.

[0005] In one possible implementation, the water replenishment container is configured as separate parts, including a main body with an opening at the top and a cap that can open and close the top of the main body, and the filter assembly is located inside the main body and can slide upward.

[0006] In one possible implementation, the cap portion has a cap groove, and the cap portion is slidably sleeved on the upper end of the body portion through the cap groove.

[0007] In one possible implementation, the steam generator further includes a limiting member and a limiting screw. The limiting member is located above the cover portion and connected to the water inlet pipe, and the limiting member has a threaded hole with its axis vertically aligned. The limiting screw passes through the threaded hole and is threadedly connected to the threaded hole, and the limiting screw is used to abut against the upper surface of the cover portion. The water inlet pipe is fixedly connected to the main body portion.

[0008] In one possible implementation, the steam generator further includes a drive shaft. The drive shaft is perpendicular to and fixedly connected to the limiting screw.

[0009] In one possible implementation, the water inlet pipe has a vertically arranged connecting section located on one side of the main body. The limiting member is elongated, with a threaded hole at one end along its length and the other end rotatably fitted over the connecting section. The steam generator further includes two limiting rings and a limiting tube. Both limiting rings are fitted and fixed over the connecting section, respectively fitting against the upper and lower surfaces of the limiting member. The limiting tube is fitted over the limiting screw and fixed to the cover.

[0010] In one possible implementation, the filter assembly includes a support plate and a filter screen. The support plate is horizontally positioned and placed on the annular support portion, and the support plate has multiple leakage holes. The filter screen is attached and fixed to the upper surface of the support plate, and the filter screen covers all the leakage holes.

[0011] In one possible implementation, the filter assembly further includes a lifting shaft. The lifting shaft is vertically positioned, penetrates the filter screen, and is fixedly connected to the support plate.

[0012] In one possible implementation, the number of electric heating rods is multiple.

[0013] In one possible implementation, the steam generator further includes a check valve. The check valve is located on a section of the water supply pipe between the water supply pump and the steam generating vessel.

[0014] In this embodiment, the annular support supports the filter assembly. Water is injected into the inlet chamber through the inlet pipe, and after being filtered by the filter assembly, it falls into the storage chamber. A water pump draws water from the storage chamber into the steam generating container through the water supply pipe. An electric heating rod heats the water in the steam generating container, and the generated steam escapes from the outlet. Because the water entering the steam generating container is filtered by the filter assembly, the problem of existing steam generators being unable to filter the water to be heated is avoided.

[0025] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 8 The steam generator provided by this utility model will now be described. The steam generator includes a water supply container 1, a filter assembly 2, a water inlet pipe 3, a steam generating container 4, an electric heating rod 5, a water supply pipe 6, and a water supply pump 7. The inner side of the water supply container 1 has a circumferentially inwardly protruding annular support portion 111. The filter assembly 2 is located inside the water supply container 1 and placed on the annular support portion 111, dividing the water supply container 1 into a water inlet chamber 101 located above the filter assembly 2 and a water storage chamber 102 located below the filter assembly 2. One end of the water inlet pipe 3 is fixedly connected to the water supply container 1 and communicates with the water inlet chamber 101. The top of the steam generating container 4 is provided with a steam outlet 41. The electric heating rod 5 is fixedly installed inside the steam generating container 4. One end of the water supply pipe 6 is fixedly connected to the water supply container 1 and communicates with the water storage chamber 102, and the other end is fixedly connected to the steam generating container 4 and communicates with the interior of the steam generating container 4. The water supply pump 7 is located on the water supply pipe 6.

[0030] The steam generator provided by this utility model, compared with the prior art, has an annular support 111 supporting the filter assembly 2. Water is injected into the water inlet chamber 101 through the water inlet pipe 3, and after being filtered by the filter assembly 2, it falls into the water storage chamber 102. The water supply pump 7 draws water from the water storage chamber 102 into the steam generating container 4 through the water supply pipe 6. The electric heating rod 5 heats the water in the steam generating container 4, and the generated steam floats out from the steam outlet 41. Because the water entering the steam generating container 4 has been filtered by the filter assembly 2, the problem of existing steam generators being unable to filter the water to be heated is avoided.

[0031] In this embodiment, whenever the water level in the steam generating container 4 drops to a preset position, the water replenishment pump 7 replenishes water into the steam generating container 4. Therefore, a liquid level sensor can be installed inside the steam generating container 4 to monitor changes in the water level.

[0032] In some embodiments, the aforementioned water supply container 1 can be adopted as follows: Figure 2 and Figure 3 The structure shown. See also Figure 2 and Figure 3 The water supply container 1 is a two-part unit, including a main body 11 with an open top and a cap 12 that can be opened and closed. The filter assembly 2 is located inside the main body 11 and can slide upwards. After a period of use, a lot of impurities will accumulate on the filter assembly 2, affecting the filtration efficiency. At this time, the cap 12 is opened to open the top of the main body 11, and then the filter assembly 2 is slid upwards and removed from the main body 11. The impurities on the filter assembly 2 are then cleaned, and finally the filter assembly 2 and the cap 12 are reset sequentially. In this embodiment, the annular support 111 is located inside the main body 11.

[0033] In some embodiments, see Figure 2 and Figure 5 The capping part 12 has a capping groove 121. The capping part 12 is slidably sleeved on the upper end of the body part 11 through the capping groove 121, thereby closing the upper end of the body part 11. When the capping part 12 slides upward and disengages from the body part 11, the upper end of the body part 11 is opened.

[0034] In some embodiments, see Figure 1The steam generator also includes a limiting member 8 and a limiting screw 9. The limiting member 8 is located above the cover portion 12 and connected to the water inlet pipe 3. The limiting member 8 has a threaded hole with its axis vertically aligned. The limiting screw 9 passes through the threaded hole and is threadedly connected to it. The limiting screw 9 is used to abut against the upper surface of the cover portion 12. The water inlet pipe 3 is fixedly connected to the main body portion 11. Thus, the limiting member 8 is indirectly connected to the main body portion 11 through the water inlet pipe 3. The limiting screw 9, which is threadedly connected to the limiting member 8, can restrict the upward movement of the cover portion 12, thereby keeping the cover portion 12 in a state that closes the upper end of the main body portion 11.

[0035] In some embodiments, see Figure 1 The steam generator also includes a drive shaft 10. The drive shaft 10 is perpendicular to and fixedly connected to the limit screw 9. It is convenient to drive the limit screw 9 to rotate via the drive shaft 10.

[0036] In some embodiments, see Figure 1 and Figure 4 The water inlet pipe 3 has a vertically arranged connecting section 31 located on one side of the main body 11. The limiting member 8 is elongated, with a threaded hole at one end and rotatably fitted onto the connecting section 31 at the other end. The steam generator also includes two limiting rings 110 and a limiting tube 120. Both limiting rings 110 are fitted and fixed onto the connecting section 31, respectively fitting against the upper and lower surfaces of the limiting member 8. The limiting tube 120 is fitted onto the limiting screw 9 and fixed to the cover 12. The two limiting rings 110 can restrict the vertical movement of the limiting member 8, thereby connecting the limiting member 8 to the water inlet pipe 3. The limiting tube 120 can restrict the rotation of the limiting member 8 through the limiting screw 9, thereby keeping the limiting screw 9 in contact with the cover 12. When the limiting screw 9 rotates upward and exits the limiting tube 120, the limiting member 8 can rotate to allow the limiting member 8 and the limiting screw 9 to avoid the space for the opening cover 12 and the filter assembly 2 to move upward, thereby facilitating the driving of the opening cover 12 to detach upward from the main body 11 and the removal of the filter assembly 2 from the main body 11.

[0037] In some embodiments, the feature filtering component 2 described above may employ, for example... Figure 2 , Figure 6 and Figure 7 The structure shown. See also Figure 2 , Figure 6 and Figure 7The filter assembly 2 includes a support plate 21 and a filter screen 22. The support plate 21 is horizontally positioned and placed on the annular support portion 111, and the support plate 21 has multiple leakage holes 211. The filter screen 22 is attached and fixed to the upper surface of the support plate 21, and the filter screen 22 covers all the leakage holes 211. Water entering the water inlet chamber 101 is filtered by the filter screen 22 and then falls through the leakage holes 211. Impurities remain on the filter screen 22. In this embodiment, the support plate 21 is circumferentially attached to the inner side surface of the body portion 11.

[0038] In some embodiments, the feature filtering component 2 described above may employ, for example... Figure 2 , Figure 6 and Figure 7 The structure shown. See also Figure 2 , Figure 6 and Figure 7 The filter assembly 2 also includes a lifting shaft 23. The lifting shaft 23 is vertically positioned, penetrates the filter screen 22, and is fixedly connected to the support plate 21. When the cover portion 12 detaches from the main body portion 11, the filter assembly 2 can be pulled out of the main body portion 11 by the lifting shaft 23. In this embodiment, the lifting shaft 23 can abut against the cover portion 12, thereby restricting the upward movement of the filter assembly 2.

[0039] In some embodiments, see Figure 2 The number of electric heating rods 5 is multiple, thereby accelerating the steam generation rate.

[0040] In some embodiments, see Figure 1 The steam generator also includes a one-way valve 130. The one-way valve 130 is located on a section of the water supply pipe 6 between the water supply pump 7 and the steam generating container 4. Steam generated by the steam generator enters the water supply pipe 6, and the one-way valve 130 restricts the movement of the steam entering the water supply pipe 6 towards the water supply pump 7. In this embodiment, the water supply pipe 6 can be fixedly connected to the top of the steam generating container 4.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
