Certain parts in certain drawings can be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0033] Embodiment 1

[0034] Reference Figures 1-9 The present embodiment provides a technical solution: a purification device for extracting organic reagent from organic matter in sediment, comprising an extract container 6, a condensing container 1 and a water bath heating container 2, the extract container 6 is used to contain extract, the extract container 6 is made of high thermal conductivity material, the condensing container 1 is arranged above the extract container 6 and is detachably assembled and connected with 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 condensing container 1 is internally provided with a condensing pipe group 7, which is in communication with the inside of the extract container 6 through a communication pipe 701. In use, the extract is first contained in the extract container 6, and the water bath heating container 2 heats the extract in the extract container 6 through water bath heating, so that CH2CL2 in the extract evaporates, the evaporated CH2CL2 enters the condensing pipe group 7 through the communication pipe 701, and then enters the bottom of the condensing container 1 after being condensed in the condensing pipe group 7, so as to realize the purification process of the extract.

[0036] By adopting the above technical scheme: the device adopts water bath heating to purify the organic reagent extracted from the organic matter in the sediment. When the extract is evaporated, the extract is evenly heated, and the temperature is easy to control, so that the evaporation of other substances in the extract can be effectively avoided, and the purification effect is poor. The device is composed of three parts, namely the extract container 6, the condensing container 1 and the water bath heating container 2. The three parts are detachably assembled and connected, so that when one part is damaged, it can be easily replaced independently, reducing the maintenance cost. After use, each part can be easily disassembled and cleaned to ensure the cleanliness of each part during secondary use.

[0037] Specifically, as shown in Figure 1 - Figure 3 To realize the condensation of the condensing container 1, in the embodiment, a partition 105 is arranged in the middle of the condensing container 1, which divides the internal space of the condensing container 1 into two independent spaces, i.e. an upper independent space and a lower independent space. The upper independent space is a condensing water space 104, and the condensing pipe group 7 is arranged in the condensing water space 104 in a ring shape. The lower independent space is a purified reagent containing space 103, and the bottom of the condensing pipe group 7 is in communication with the inside of the purified reagent containing space 103. The condensing water space 104 is connected with a hot water outlet pipe 101 at the top and a cold water inlet pipe 100 at the bottom. In use, the evaporated substance enters the condensing pipe group 7 through the communication pipe 701. At this time, cold water is introduced into the condensing water space 104 through the cold water inlet pipe 100, and heat exchange is generated with the condensing pipe group 7. The heated cold water is discharged through the hot water outlet pipe 101, and the evaporated substance in the condensing pipe group 7 is condensed and flows downward to the purified reagent containing space 103, so as to realize the evaporation-condensation purification process.

[0038] Specifically, as shown in Figure 1 - Figure 3As shown, in order to facilitate the discharge of the purification reagent in the purification reagent containing space 103, in this embodiment, the bottom of the purification reagent containing space 103 is connected with a discharge pipe 107, the top of the condenser 1 is provided with a central pipe 102, the central pipe 102 is in communication with the inside of the purification reagent containing space 103, and the purified CH2CL2 in the purification reagent containing space 103 can be discharged through the discharge pipe 107, and the setting of the central pipe 102 can balance the pressure in the purification reagent containing space 103, facilitating the discharge of CH2CL2.

[0039] Specifically, as shown in the figure, Figure 5 - Figure 6 As shown, in order to realize water bath heating, in this embodiment, the water bath heating container 2 adopts a cylindrical shape, a plurality of fixed columns 204 are arranged 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, one side of the water bath heating container 2 is provided with a water filling pipe 201, and the front surface of the water bath heating container 2 is provided with a control panel 200. The ring-shaped electric heating device 205 is used for heating the medium in the water bath heating container 2. Since the ring-shaped electric heating device 205 adopts a ring structure, the heating in the water bath heating container 2 is more uniform, so that each part of the extract container 6 is uniformly heated, thereby achieving the effect of conveniently controlling the temperature of the extract in the extract container 6.

[0040] Specifically, as shown in the figure, 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 respectively installed at the center position of the water bath heating container 2 and inside the extract container 6. Among them, the first temperature sensor 206 and the second temperature sensor 601 can monitor the temperature inside the water bath heating container 2 and the extract container 6 in real time, and upload to the controller, and control the heating temperature of the ring-shaped electric heating device 205 through the controller.

[0041] Specifically, as shown in the figure, 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 sliding rod 209 is installed in the water bath heating container 2 along the vertical direction, a liquid level sensor 208 is slidingly installed on the sliding rod 209, and a float 207 is 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 monitoring the water level in the water bath heating container 2. When the liquid level is lower than the set value, a signal is transmitted to the controller, and the controller controls the water replenishment.

[0042] Specifically, as shown in the figure, Figure 1 - Figure 5As shown, in order to facilitate the water replenishment control of the water bath heating container 2, in the embodiment, one end of the water feeding pipe 201 is connected with a three-way valve 4, the three-way valve 4 is installed with an electromagnetic control valve 400, one joint of the three-way valve 4 is connected with the hot water outlet pipe 101 through the water outlet hose 3, and the other joint is connected with the external condensed water storage device. When the liquid level sensor 208 monitors 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 feeding pipe 201 in the three-way valve 4 to communicate with 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 feeding pipe 201 for water replenishment, until the liquid level sensor 208 monitors 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 feeding pipe 201 in the three-way valve 4 to be closed with the water outlet hose 3, and the other joint is conducted, and water replenishment is no longer performed in the water bath heating container 2. The structure setting makes the water replenishment of the water bath heating container 2 in the device through the condensed water for water replenishment, without the need of additional water injection equipment, which reduces the overall cost of the equipment. And this uses the hot water in the condensed water to replenish the water bath heating container 2, which reduces the heating process when the cold water is injected, reduces the temperature change of the water in the water bath heating container 2, and thus ensures the efficiency of the water bath heating (when external cold water is used for water replenishment, a long heating process is needed after the cold water is injected, which affects the water bath heating effect. When external hot water is used for water replenishment, additional water heating equipment is needed at all times, which causes the increase of the overall purification cost).
