In addition, the use of hot water in the condensed water to replenish the water bath heating container reduces the heating process when injecting cold water, reduces the temperature change of water in the water bath heating container, thereby ensuring the efficiency of water bath heating.

[0007] (II) Technical solution

[0009] The condensation container is provided with a condensation tube group, which is connected to the inside of the extract container through a connecting tube. When in use, the extract is first placed in the extract container, and the water bath heating container heats the extract inside the extract container through the water bath heating method, so that CH 2 CL 2 Evaporation, evaporation of CH 2 CL 2 It enters the condensation tube group through the connecting pipe, and after condensation in the condensation tube group, it enters the bottom of the condensation container to realize the purification process of the extract.

[0010] As a further description of the above technical solution: a partition is provided in the middle of the condensation container, and the internal space of the condensation container is divided into two independent spaces, the upper independent space is the condensation water space, the condensation tube group is annular and distributed in the condensation water space, and the lower space is the purification reagent accommodating space. The bottom of the condensation tube group is connected to the interior of the purification reagent accommodating space, and the top of the condensation water space is connected with a hot water outlet pipe, and the bottom is connected with a cold water inlet pipe. When in use, the evaporated material first enters the condensation tube group through the connecting pipe. At this time, cold water is introduced into the condensation water space through the cold water inlet pipe, and heat exchange is generated with the condensation tube group. After the cold water becomes hot, it is discharged from the hot water outlet pipe, and the evaporated material in the condensation tube group is condensed and flows downward to the purification reagent accommodating space, realizing the evaporation-condensation purification process.

[0011] As a further description of the above technical solution: the bottom of the purification reagent accommodating space is connected to a discharge pipe, the top of the condensation container is provided with a central tube, the central tube is communicated with the interior of the purification reagent accommodating space, and the purified CH in the purification reagent accommodating space can be discharged through the discharge pipe. 2 CL 2 The central tube can balance the pressure in the purification reagent storage space, making it convenient for CH 2 CL 2 discharge.

[0012] As a further description of the above technical solution: the water bath heating container is cylindrical, and a plurality of fixed columns are distributed in a circular array inside the water bath heating container, and an annular electric heating device is fixedly installed through the plurality of fixed columns. A water supply pipe is installed on one side of the water bath heating container, and a control panel is installed on the front surface of the water bath heating container. The annular electric heating device is used to heat the medium of the water bath heating container. Since the annular electric heating device adopts an annular structure, the heating inside the water bath heating container is more uniform, so that each part of the extract container is heated evenly, thereby achieving the effect of facilitating the temperature control of the extract in the extract container.

[0013] As a further description of the above technical solution: In order to facilitate the control of the temperature inside the water bath heating container and the extract container, in the present embodiment, it is characterized in that a first temperature sensor and a second temperature sensor are installed at the center position of the water bath heating container and inside the extract container respectively, wherein the first temperature sensor and the second temperature sensor can monitor the internal temperature of the water bath heating container and the extract container in real time, and upload them to the controller, and the heating temperature of the annular electric heating device is controlled by the controller.

One of the joints of the three-way valve is connected to the hot water outlet pipe through a water outlet hose, and the other joint is connected to an external condensed water storage device. When the liquid level sensor detects that the water level in the water bath heating container is lower than the set value, the electromagnetic control valve controls the water adding pipe in the three-way valve to be connected to the water outlet hose, and the other joint is closed. At this time, the condensed hot water enters the water bath heating container through the water adding pipe for water replenishment until the liquid level sensor detects that the water level in the water bath is lower than the set value. When the water level in the heating container reaches the set value, the electromagnetic control valve controls the water filling pipe and the water outlet hose in the three-way valve to be closed, and the other joint is turned on, and water is no longer added to the water bath heating container. This structural setting enables the water bath heating container in the device to be replenished with its own condensed water, without the need for additional water injection equipment, thereby reducing the overall cost of the equipment. In addition, this method of using hot water from the condensed water to replenish the water bath heating container reduces the heating process when injecting cold water, reduces the temperature change of the water in the water bath heating container, and thus ensures the efficiency of water bath heating.

[0016] As a further description of the above technical solution: it is characterized in that a cover is arranged above the extract container, the edge of the cover is provided with a cornice portion, and the top of the cover is provided with a pressure relief valve.

When the extract container is installed in the water bath heating container, the snap-fitting ring frame is snapped onto the step slot, and an addition tube for adding extract into the extract container is connected to the extract container. An opening for accommodating the addition tube is also provided on the top of the water bath heating container. Such a structural arrangement enables the water bath heating container and the extract container to be accurately aligned when connected and assembled, and the overall stability after assembly is higher.

[0018] As a further description of the above technical solution: an assembly tube is provided at the upper center of the extract container, and a connecting part is provided at the bottom of the condensation container. The connecting part is inserted above the assembly tube through a threaded connection, and the connecting part adopts a two-section tubular structure, wherein the upper tubular structure is connected to the interior of the condensation container, the discharge pipe is connected to the upper tubular structure, and the lower tubular structure is connected to the interior of the extract container through the assembly tube to form a circulation channel for the evaporated substance.

[0019] In the above technical scheme, the present invention provides a purification device for extracting organic reagents from organic matter in sediments. The device uses a water bath heating method to purify the organic reagents extracted from organic matter in sediments. When the extract is evaporated, the extract is heated evenly and the temperature is conveniently controlled, which can effectively prevent other substances in the extract from evaporating and causing the purification effect to deteriorate. The device is composed of three parts, namely, an extract container, a condensation container and a water bath heating container. The three parts are detachably assembled and connected. Therefore, when a part is damaged, it can be easily replaced independently to reduce maintenance costs. After use, each part can be easily disassembled for cleaning to ensure the cleanliness of each part when it is used again.

[0020] The water bath heating container in the device is replenished with water through its own condensed water, so there is no need for additional water injection equipment, which reduces the overall cost of the equipment. In addition, the use of hot water in the condensed water to replenish the water bath heating container reduces the heating process when injecting cold water and reduces the temperature change of the water in the water bath heating container, thereby ensuring the efficiency of water bath heating.

[0032] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0033] Example 1

[0034] Reference Figure 1-9 :This embodiment provides a technical solution: a purification device for extracting organic reagents from organic matter in sediments, comprising an extract container 6, a condensation container 1 and a water bath heating container 2, wherein the extract container 6 is used to contain the extract, and the extract container 6 is made of a high thermal conductivity material, the condensation container 1 is arranged above the extract container 6, and is detachably assembled and connected to the extract container 6, the water bath heating container 2 is arranged below the extract container 6 and covers the extract container 6, and the water bath heating container 2 and the extract container 6 are detachably assembled and connected;

[0035] The condensation container 1 is provided with a condensation tube group 7, which is connected to the inside of the extract container 6 through a connecting pipe 701. When in use, the extract is first placed in the extract container 6, and the water bath heating container 2 heats the extract in the extract container 6 by means of water bath heating, so that CH 2 CL 2 Evaporation, evaporation of CH2 CL 2 The extract enters the condensation tube group 7 through the connecting tube 701, and after being condensed in the condensation tube group 7, enters the bottom of the condensation container 1, thereby realizing the purification process of the extract.

[0036] By adopting the above technical solution: the device uses water bath heating to extract organic reagents from organic matter in the sediment for purification. When the extract is evaporated, the extract is heated evenly and the temperature is easy to control. This can effectively prevent other substances in the extract from evaporating, resulting in poor purification effect. The device is composed of three parts, namely the extract container 6, the condensation container 1 and the water bath heating container 2. The three parts are detachably assembled and connected. Therefore, when a part is damaged, it can be easily replaced independently to reduce maintenance costs. After use, the various parts can be easily disassembled for cleaning to ensure the cleanliness of each part when used again.

[0037] Specifically, Figure 1 - Figure 3 As shown, in order to achieve condensation of the condensation container 1, in this embodiment, a partition 105 is provided in the middle of the condensation container 1, and the internal space of the condensation container 1 is divided into two independent spaces, the upper independent space is the condensation water space 104, the condensation tube group 7 is annular and distributed in the condensation water space 104, and the lower space is the purification reagent accommodating space 103. The bottom of the condensation tube group 7 is connected to the inside of the purification reagent accommodating space 103, and the top of the condensation water space 104 is connected with a hot water outlet pipe 101, and the bottom is connected with a cold water inlet pipe 100. When in use, the evaporated material first enters the condensation tube group 7 through the connecting pipe 701. At this time, cold water is introduced into the condensation water space 104 through the cold water inlet pipe 100, and heat exchange is generated with the condensation tube group 7. After the cold water becomes hot, it is discharged from the hot water outlet pipe 101, and the evaporated material in the condensation tube group 7 is condensed and flows downward to the purification reagent accommodating space 103, realizing the evaporation-condensation purification process.

[0038] Specifically, Figure 1 - Figure 3 As shown, in order to facilitate the discharge of the purification reagent in the purification reagent accommodating space 103, in this embodiment, the bottom of the purification reagent accommodating space 103 is connected to a discharge pipe 107, and the top of the condensation container 1 is provided with a central tube 102, and the central tube 102 is connected to the inside of the purification reagent accommodating space 103. The purified CH in the purification reagent accommodating space 103 can be discharged through the discharge pipe 107. 2 CL 2 The central tube 102 can balance the pressure in the purification reagent storage space 103, which is convenient for CH 2 CL 2 discharge.

[0039] Specifically, Figure 5 - Figure 6 As shown, in order to achieve water bath heating, in this embodiment, the water bath heating container 2 is cylindrical, and a plurality of fixed columns 204 are distributed in a ring array inside the water bath heating container 2, and a ring-shaped electric heating device 205 is fixedly installed through the plurality of fixed columns 204. A water supply pipe 201 is installed on one side of the water bath heating container 2, and a control panel 200 is installed on the front surface of the water bath heating container 2. The ring-shaped electric heating device 205 is used to heat the medium of the water bath heating container 2. Since the ring-shaped electric heating device 205 adopts a ring-shaped structure, the heating inside the water bath heating container 2 is more uniform, so that each part of the extract container 6 is heated evenly, thereby achieving the effect of facilitating the control of the temperature of the extract in the extract container 6.

[0040] Specifically, Figure 4 - Figure 6 As shown, in order to facilitate the control of the temperature inside the water bath heating container 2 and the extract container 6, in this embodiment, a first temperature sensor 206 and a second temperature sensor 601 are installed at the center position of the water bath heating container 2 and inside the extract container 6, respectively, wherein the first temperature sensor 206 and the second temperature sensor 601 can monitor the internal temperature of the water bath heating container 2 and the extract container 6 in real time, and upload them to the controller, and the heating temperature of the annular electric heating device 205 is controlled by the controller.

[0041] Specifically, Figure 5 - Figure 7 As shown, in order to ensure that the water in the water bath heating container 2 can always immerse the extract container 6, thereby ensuring the effect of water bath heating, in this embodiment, a slide bar 209 is installed vertically inside the water bath heating container 2, and a liquid level sensor 208 is slidably installed on the slide bar 209. Floats 207 are installed at both ends of the liquid level sensor 208. When the water level in the water bath heating container 2 changes, the float 207 drives the liquid level sensor 208 to float, thereby realizing the monitoring of the water level in the water bath heating container 2. When the liquid level is lower than the set value, the signal is transmitted to the controller, and the water replenishment is controlled by the controller.

[0042] Specifically, Figure 1 - Figure 5As shown, in order to facilitate the water replenishment control of the water bath heating container 2, in this embodiment, one end of the water adding pipe 201 is connected to the three-way valve 4, and the three-way valve 4 is installed with an electromagnetic control valve 400. One of the joints of the three-way valve 4 is connected to the hot water outlet pipe 101 through the water outlet hose 3, and the other joint is connected to the external condensed water storage device. When the liquid level sensor 208 detects that the water level in the water bath heating container 2 is lower than the set value, the electromagnetic control valve 400 controls the water adding pipe 201 in the three-way valve 4 to be connected to the water outlet hose 3, and the other joint is closed. At this time, the condensed hot water enters the water bath heating container 2 through the water adding pipe 201 for water replenishment, until the liquid level sensor 208 detects that the water level in the water bath heating container 2 reaches the set value. At this time, the electromagnetic control valve 400 controls The water supply pipe 201 in the three-way valve 4 is closed to the water outlet hose 3, and the other joint is connected, and water is no longer replenished into the water bath heating container 2. Such a structural arrangement enables the water in the water bath heating container 2 in the device to be replenished through its own condensed water, without the need for additional water injection equipment, thereby reducing the overall cost of the equipment. In addition, the use of hot water in the condensed water to replenish the water bath heating container 2 reduces the heating process when cold water is injected, and reduces the temperature change of the water in the water bath heating container 2, thereby ensuring the efficiency of water bath heating (when external cold water is used for water replenishment, a longer heating process is required after the cold water is added, which affects the water bath heating effect. When external hot water is used for water replenishment, additional water heating equipment needs to be ready at all times, resulting in an increase in the overall purification cost).

[0045] Specifically, Figure 1 - Figure 5As shown, in order to ensure the stability of the connection between the water bath heating container 2 and the extract container 6, in this embodiment, a step groove 202 is provided on the inner side of the top of the water bath heating container 2 in the circumferential direction, and a snap ring frame 502 that can be adapted to the step groove 202 is provided on the inner side of the cover 5.

An opening 203 for accommodating the addition tube 600 is also provided on the top of the water bath heating container 2. Such a structural arrangement allows the water bath heating container 2 and the extract container 6 to be accurately aligned when connected and assembled, and the overall stability after assembly is higher.

[0046] Specifically, Fig. 9 As shown, in order to realize the detachable assembly connection between the condensation container 1 and the extract container 6, in this embodiment, a mounting tube 602 is provided at the upper center of the extract container 6, and a connecting portion 106 is provided at the bottom of the condensation container 1, and the connecting portion 106 is inserted above the mounting tube 602 through a threaded connection.
