Description

Technical Field

[0001] The utility model belongs to the technical field of waste heat exchange, and more specifically, relates to a waste heat exchange mechanism for a heating boiler. Background Art

[0002] A steam boiler refers to a boiler equipment that produces steam. It is a special equipment. When a steam boiler is used for heating, it will emit heat. At this time, a waste heat exchange mechanism is needed to recover and reuse the emitted heat.

[0003] When recovering waste heat, the existing device can reduce the flow rate through the valve to improve the recovery effect. However, when the valve is damaged, it needs to be replaced before it can continue to be used, and emergency adjustments cannot be made, which makes it less practical. When the liquid flows through the recovery seat, the contact area with the recovery seat is small, resulting in a reduction in the waste heat exchange effect. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a heating boiler waste heat exchange mechanism to solve the problem that when the existing device recovers waste heat, although the flow rate can be reduced through the valve to achieve the purpose of improving the recovery effect, when the valve is damaged, the valve needs to be replaced before it can continue to be used, and emergency adjustment cannot be performed, which has low practicality; when the liquid flows through the recovery seat, the contact area with the recovery seat is small, resulting in a reduced waste heat exchange effect.

[0005] The purpose and effect of the waste heat exchange mechanism for a heating boiler in the utility model are achieved by the following specific technical means:

[0006] A waste heat exchange mechanism for a heating boiler comprises a boiler body; the boiler body is placed on the ground, and a recovery seat with an annular structure is sleeved on the boiler body, the interior of the recovery seat is a hollow structure, a liquid inlet pipe is welded to the left end face of the recovery seat, and a sleeve is welded to the right end face of the recovery seat, and both the liquid inlet pipe and the sleeve are connected to the recovery seat; a block seat is welded in a linear array inside the recovery seat, the block seat is annular in structure, and each block seat is provided with a through hole in the shape of an annular array.

[0007] Furthermore, a discharge pipe is connected to the inner thread of the sleeve, the discharge pipe is connected to the radiator, and a valve is installed on the discharge pipe.

[0008] Furthermore, the left end of the discharge pipe is in a sealed state, and discharge holes are opened in a circular array on the left side of the outer wall of the discharge pipe. The discharge holes are circular hole structures. When the discharge holes are hidden inside the sleeve, the discharge holes are in a blocked state.

[0009] Furthermore, a mounting seat is welded on the outer wall of the boiler body, a filter box is fixed on the mounting seat, a cover plate is buckled on the top of the filter box, a liquid supply pipe is connected to the cover plate; the filter box is connected to the liquid inlet pipe.

[0010] Furthermore, an iron filter screen is fixed in the filter box, the liquid supply pipe is located at the rear side of the iron filter screen, and the liquid inlet pipe is located at the front side of the iron filter screen.

[0011] Furthermore, a sliding frame is slidably mounted on the cover plate, a cleaning brush is fixed to one end below the sliding frame, and the cleaning brush contacts the iron filter screen; an electric cylinder is fixed to the top surface of the cover plate, the electric cylinder is electrically connected to the control switch of the peripheral device, and the protruding end of the electric cylinder is fixed to the sliding frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this application, through the setting of the baffle and the through hole, after the liquid enters the recovery seat through the liquid inlet pipe, it needs to pass through the through hole on the baffle and then be discharged through the sleeve. Under the obstruction of the baffle, the liquid flow rate can be reduced, thereby improving the waste heat recovery effect of the boiler body, and the contact area between the recovery seat and the liquid can be expanded through the baffle, which has a better heating effect on the liquid.

[0014] In this application, through the arrangement of the sleeve, discharge pipe, valve and discharge hole, on the one hand, the flow rate of the liquid can be adjusted by adjusting the flow of the valve; on the other hand, when the valve is damaged, the discharge pipe can be rotated to adjust the number of discharge holes exposed from the sleeve to achieve flow rate adjustment. When the flow stops, the discharge pipe can be rotated to hide all the discharge holes in the sleeve, which has a good emergency effect.

[0015] In this application, the sliding frame, cleaning brush and electric cylinder are set to control the reciprocating extension and contraction of the electric cylinder, and the electric cylinder drives the sliding frame and the cleaning brush to move up and down. At this time, the cleaning brush can be used to temporarily clean the debris covering the iron filter net, thereby extending the cleaning cycle of the iron filter net and having high practicality.

[0029] The utility model provides a waste heat exchange mechanism for a heating boiler, comprising a boiler body 1; the boiler body 1 is placed on the ground, and a recovery seat 2 with an annular structure is sleeved on the boiler body 1, the interior of the recovery seat 2 is a hollow structure, a liquid inlet pipe 201 is welded to the left end face of the recovery seat 2, and a sleeve 202 is welded to the right end face of the recovery seat 2, and the liquid inlet pipe 201 and the sleeve 202 are both connected to the recovery seat 2; a baffle 203 is welded in a linear array inside the recovery seat 2, and the baffle 203 is an annular structure, and each baffle 203 is provided with a through hole 204 in an annular array. During use, after the liquid enters the interior of the recovery seat 2 through the liquid inlet pipe 201, it needs to pass through the through hole 204 on the baffle 203, and then it can be discharged through the sleeve 202. Under the obstruction of the baffle 203, the liquid flow rate can be reduced, thereby improving the waste heat recovery effect of the boiler body 1.

[0030] Among them, the inner thread of the sleeve 202 is connected to a discharge pipe 205, the discharge pipe 205 is connected to the radiator, and a valve 206 is installed on the discharge pipe 205. During use, the flow rate of the valve 206 can be adjusted to achieve liquid flow rate adjustment.

[0031] Among them, the left end of the discharge pipe 205 is in a sealed state, and the left side of the outer wall of the discharge pipe 205 is provided with discharge holes 207 in a circular array. The discharge holes 207 are circular hole structures. When the discharge holes 207 are hidden inside the sleeve 202, the discharge holes 207 are blocked. During use, when the valve 206 is damaged, the discharge pipe 205 is rotated to adjust the number of discharge holes 207 exposed from the sleeve 202 to achieve flow rate adjustment. When the flow stops, the discharge pipe 205 is rotated to hide all the discharge holes 207 in the sleeve 202.

[0032] Among them, a mounting seat is welded on the outer wall of the boiler body 1, and a filter box 3 is fixed on the mounting seat. A cover plate 301 is buckled on the top of the filter box 3, and a liquid supply pipe is connected to the cover plate 301; the filter box 3 is connected to the liquid inlet pipe 201.

[0033] An iron filter screen 302 is fixed in the filter box 3 , the liquid supply pipe is located at the rear side of the iron filter screen 302 , and the liquid inlet pipe 201 is located at the front side of the iron filter screen 302 .

[0034] Example 2:

After filtering through the iron filter 302, it is delivered to the recovery seat 2. After the liquid enters the recovery seat 2 through the liquid inlet pipe 201, it needs to pass through the through hole 204 on the block 203 and then be discharged through the sleeve 202. Under the obstruction of the block 203, the liquid flow rate can be reduced. Finally, the liquid is discharged into the radiator through the discharge pipe 205. During use, the flow rate of the valve 206 can be adjusted to achieve liquid flow rate adjustment. When the valve 206 is damaged, , rotate the discharge pipe 205 and adjust the number of discharge holes 207 exposed from the sleeve 202 to achieve flow rate adjustment.
