Description

Technical Field

[0001] The utility model belongs to the technical field of food processing equipment, and more specifically relates to a double-path steam converging system. Background Art

[0002] In the production process of instant noodles, noodles need to be steamed. The current traditional practice is: first, the raw steam generated by the raw steam generator is cooled and decompressed and then passed into the sub-cylinder, and then the MVR steam is produced by the MVR evaporator and passed into the sub-cylinder. The steam in the sub-cylinder is used by the noodle steamer. The pressure of the raw steam passed into the sub-cylinder is 60KPa and the temperature is 180℃; while the pressure of the MVR steam passed into the sub-cylinder is 60KPa and the temperature is 110℃. When the steam inlet valve of the MVR steam on the sub-cylinder is opened, since the temperature of the raw steam in the sub-cylinder is higher than that of the MVR steam, the raw steam in the sub-cylinder will quickly flow into the compressor of the MVR evaporator, causing the compressor to overheat and alarm, and the system cannot operate normally. Utility Model Content

[0003] The utility model aims to provide a two-way steam merging system, aiming to solve the problem that the raw steam in the sub-cylinder of the existing two-way steam merging system will flow into the compressor of the MVR evaporator, thereby causing the compressor to over-temperature alarm and the system cannot operate normally.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide a two-way steam converging system, including: a steam cylinder and a constant pressure stabilizer; the steam cylinder is respectively provided with a raw steam inlet and an MVR steam inlet; the constant pressure stabilizer comprises a tank body, an upper baffle, a lower baffle and a steam pipe; the top opening of the tank body is communicated with the MVR steam inlet, the bottom opening of the tank body is communicated with the MVR evaporator, the upper baffle, the lower baffle and the steam pipe are all located inside the tank body, the upper baffle and the lower baffle divide the inner cavity of the tank body from top to bottom into an upper cavity, a heat exchange cavity and a lower cavity, hot water is passed through the heat exchange cavity, the steam pipe penetrates the heat exchange cavity from top to bottom and is communicated with the upper cavity and the lower cavity, the pressure and temperature in the heat exchange cavity are both lower than the pressure and temperature of the raw steam, and a water inlet pipe and a water outlet pipe are installed on the tank body, and the water inlet pipe and the water outlet pipe are both communicated with the heat exchange cavity.

[0005] In a possible implementation, there are multiple steam pipes, which are evenly distributed on the upper baffle and the lower baffle.

[0006] In a possible implementation, a constant pressure valve is installed on the water outlet pipe.

[0007] In a possible implementation, the tank body includes a tank body and a top cover; the top cover is detachably mounted on the top of the tank body.

[0008] In a possible implementation, a first sealing ring is installed between the upper partition plate, the lower partition plate and the inner wall of the tank body.

[0009] In a possible implementation, a connecting rod is fixedly installed between the upper partition and the lower partition, the upper end of the steam pipe is fixedly connected to the upper partition, and the lower end of the steam pipe is slidably matched with the lower partition.

[0010] In a possible implementation, a second sealing ring is installed between the steam pipe and the lower partition.

[0011] In a possible implementation, the connecting rod includes a first connecting rod, a second connecting rod and a sleeve; the first connecting rod is fixedly connected to the upper partition, the second connecting rod is fixedly connected to the lower partition, and the sleeve is respectively connected to the first connecting rod and the second connecting rod by threads with opposite thread rotation directions.

[0012] In a possible implementation manner, a handle is hingedly mounted on the outer side of the sleeve.

[0013] In a possible implementation, a receiving cavity for accommodating the handle is provided on the outer side wall of the sleeve.

[0014] Compared with the prior art, the solution shown in the embodiment of the present application is a two-way steam converging system of the utility model. Under normal circumstances, the raw steam enters the sub-cylinder through the raw steam inlet, and the steam generated by the MVR evaporator will enter the lower cavity from the bottom of the tank body, and then enter the upper cavity through the steam pipe, and finally enter the sub-cylinder. By arranging a water inlet pipe and a water outlet pipe on the tank body, it is convenient to provide hot water for the heat exchange cavity. When the raw steam in the sub-cylinder flows back to one side of the MVR evaporator, the raw steam will enter the steam pipe in the tank body and exchange heat with the hot water in the heat exchange cavity. Since the pressure and temperature of the raw steam are greater than the pressure and temperature of the hot water in the heat exchange cavity, the temperature of the raw steam after heat exchange is reduced to be consistent with the temperature of the MVR steam, thereby avoiding the high-temperature raw steam from flowing back to the compressor of the MVR evaporator, achieving the purpose of protecting the MVR evaporator and ensuring the normal operation of the system.

DETAILED DESCRIPTION

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] Please also read Figure 1 and Figure 2Now, a dual-path steam converging system provided by the utility model is described. The dual-path steam converging system comprises: a steam sub-cylinder 1 and a constant pressure stabilizer; the sub-cylinder 1 is provided with a raw steam inlet 101 and an MVR steam inlet 102 respectively; the constant pressure stabilizer comprises a tank body 201, an upper partition 202, a lower partition 203 and a steam pipe 204; the top opening of the tank body 201 is connected to the MVR steam inlet 102, the bottom opening of the tank body 201 is connected to the MVR evaporator, and the upper partition 202, the lower partition 203 and the steam pipe 204 are all located inside the tank body 201. The upper partition 202 and the lower partition 203 divide the inner cavity of the tank body 201 from top to bottom into an upper cavity 205, a heat exchange cavity 206 and a lower cavity 207. Hot water is passed through the heat exchange cavity 206. The steam pipe 204 penetrates the heat exchange cavity 206 from top to bottom and is connected with the upper cavity 205 and the lower cavity 207. The pressure and temperature in the heat exchange cavity 206 are lower than the pressure and temperature of the raw steam. An inlet pipe 208 and an outlet pipe 209 are installed on the tank body 201, and the inlet pipe 208 and the outlet pipe 209 are both connected with the heat exchange cavity 206.

[0022] The dual-path steam converging system provided in this embodiment is compared with the prior art. Under normal circumstances, the raw steam enters the steam sub-cylinder 1 through the raw steam inlet 101, and the steam generated by the MVR evaporator enters the lower cavity 207 from the bottom of the tank body 201, and then enters the upper cavity 205 through the steam pipe 204, and finally enters the steam sub-cylinder 1. By arranging the water inlet pipe 208 and the water outlet pipe 209 on the tank body 201, it is convenient to provide hot water for the heat exchange cavity 206. When the raw steam in the steam sub-cylinder 1 flows back to the side of the MVR evaporator, the raw steam enters the steam pipe 204 in the tank body 201 and exchanges heat with the hot water in the heat exchange cavity 206. Since the pressure and temperature of the raw steam are greater than the pressure and temperature of the hot water in the heat exchange cavity 206, the temperature of the raw steam after heat exchange is reduced to be consistent with the temperature of the MVR steam, thereby avoiding the high-temperature raw steam from flowing back to the compressor of the MVR evaporator, achieving the purpose of protecting the MVR evaporator and ensuring the normal operation of the system.

[0023] It should be noted that the pressure and temperature of the raw steam are 60 KPa and 180° C., the pressure and temperature of the MVR steam are 60 KPa and 110° C., and the pressure and temperature of the hot water in the heat exchange chamber 206 are 42 KPa and 110° C.

[0024] In some embodiments, see Figure 2, there are multiple steam pipes 204, which are evenly distributed on the upper partition 202 and the lower partition 203. In this embodiment, there are multiple steam pipes 204, which are all arranged in the vertical direction. The hot water in the heat exchange chamber 206 is located in the space between adjacent steam pipes 204. The refluxed raw steam enters multiple steam pipes 204 at the same time, and the cooling efficiency of the raw steam is improved by increasing the heat exchange area.

[0025] In some embodiments, see Figure 1 and Figure 2 , a constant pressure valve 210 is installed on the water outlet pipe 209. In this embodiment, the pressure of the hot water after heat exchange will rise, so it will cause the pressure in the heat exchange chamber 206 to rise, and the constant pressure valve 210 will automatically open to discharge part of the steam in the heat exchange chamber 206 from the water outlet pipe 209, so that the pressure and temperature in the heat exchange chamber 206 remain stable (that is, the pressure and temperature in the heat exchange chamber 206 are stable at 42KPa and 110°C).

[0026] In some embodiments, see Figure 1 The tank body 201 includes a tank body 211 and a top cover 212; the top cover 212 is detachably mounted on the top of the tank body 211. In this embodiment, the tank body 201 includes a conical outer shell of an upper and lower section and a cylindrical outer shell of a middle section. The tank body 211 includes a conical outer shell of a middle section and a conical outer shell at the lower end, and the top cover 212 is an upper conical outer shell. The top cover 212 is fixedly connected to the tank body 211 by fasteners. The operator opens the top cover 212 to realize the disassembly and assembly operation of the parts in the tank body 201.

[0027] In some embodiments, see Figure 2 A first sealing ring 213 is installed between the upper partition 202 and the lower partition 203 and the inner wall of the tank body 211. In this embodiment, the upper partition 202 and the lower partition 203 are both disc-shaped. The outer circumference of the upper partition 202 and the lower partition 203 is fixedly installed with a first sealing ring 213. The first sealing ring 213 is used to seal between the upper partition 202 and the lower partition 203 and the inner wall of the tank body 211, thereby ensuring the sealing of the heat exchange chamber 206.

[0028] In some embodiments, see Figure 2A connecting rod 214 is fixedly installed between the upper partition 202 and the lower partition 203, the upper end of the steam pipe 204 is fixedly connected to the upper partition 202, and the lower end of the steam pipe 204 is slidably matched with the lower partition 203. In this embodiment, there are multiple connecting rods 214, which are evenly arranged along the outer circumference of the upper partition 202 and the lower partition 203. The connecting rod 214 is used to connect the upper partition 202 and the lower partition 203, so that the upper partition 202 and the lower partition 203 form a whole, thereby facilitating the disassembly and assembly of the upper partition 202 and the lower partition 203. The upper end of the steam pipe 204 is fixed to the upper partition 202 by welding, and the lower end of the steam pipe 204 is slidably matched with the lower partition 203 and extends downward into the lower cavity 207.

[0029] In some embodiments, see Figure 2 A second sealing ring 215 is installed between the steam pipe 204 and the lower partition 203. In this embodiment, the second sealing ring 215 is fixedly installed on the lower partition 203. The second sealing ring 215 is used to ensure the sealing between the steam pipe 204 and the lower partition 203.

[0030] In some embodiments, see Figure 3 , the connecting rod 214 includes a first connecting rod 216, a second connecting rod 217 and a sleeve 218; the first connecting rod 216 is fixedly connected to the upper partition 202, the second connecting rod 217 is fixedly connected to the lower partition 203, and the sleeve 218 is respectively connected to the first connecting rod 216 and the second connecting rod 217 by threads, and the threads are rotated in opposite directions. In this embodiment, the upper end of the first connecting rod 216 is welded and fixed to the bottom surface of the upper partition 202, and the lower end of the second connecting rod 217 is welded and fixed to the top surface of the lower partition 203. The sleeve 218 is used to connect the first connecting rod 216 and the second connecting rod 217. The sleeve 218 is provided with an internal thread that matches the first connecting rod 216 and the second connecting rod 217, and the threads are rotated in opposite directions. By driving the sleeve 218 to rotate, the vertical length of the connecting rod 214 is changed, that is, the distance between the upper partition 202 and the lower partition 203 is changed, so as to achieve the purpose of adjusting the heat exchange area.

[0031] In some embodiments, see Figure 3 , a handle 219 is hingedly mounted on the outer side of the sleeve 218. In this embodiment, the handles 219 are symmetrically arranged on both sides of the sleeve 218. The operator can hold the handle 219 to make the driving sleeve 218 rotate more conveniently and labor-saving.

[0032] In some embodiments, see Figure 3, a storage cavity 220 for accommodating a handle 219 is provided on the outer wall of the sleeve 218. In this embodiment, the hinge axis of the handle 219 is located at the top of the storage cavity 220. By storing the handle 219 in the storage cavity 220, the space occupied by the handle 219 is saved. In order to ensure the stability of the handle 219 in the storage cavity 220, the hinge axis of the handle 219 adopts a damping axis. The connecting rod 214 and the handle 219 are both made of polyether ketone (PEEK). PEEK has extremely high temperature resistance and can work at high temperatures (up to 300°C) for a long time.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
