[0033] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] The first embodiment of this application is:

[0035] See also Figures 1 to 4 ,in Figure 1 This is a schematic diagram of the overall structure of the shield machine construction mud and water separation and recycling device. Figure 2 1 is a schematic diagram of the installation structure of the diversion hole column 111. Figure 3 105 is a schematic diagram of the installation structure of the diversion baffle 105.

[0036] The present invention provides a shield machine construction mud and water separation and recycling device: comprising a base frame 101, a top box 102, an inlet channel 103 and a recovery component, the recovery component comprising a separation filter plate 104, a diverter baffle 105, a mounting bracket 106, a heating cylinder 107, a discharge pipe 108, a heating component, a control component, an agitation component and a sweeping component, the heating component comprising a heating fan 109, a guide channel 110, a diverter hole column 111 and a derivation component, the control component comprising a controller 112, a weight sensor 113, a derivation valve 114, a driving component and a linkage component, the The outlet component includes a guide channel 110, a condensation winding 116 and a discharge pipe 117. The driving component includes a driving shaft 118, a driving motor 119 and a sleeve bevel gear 120. The linkage component includes a driving shaft 121 and a driving bevel gear 122. The above-mentioned solution solves the problem that when the mud wastewater generated during the construction of the shield mechanism is directly discharged, it will not only cause a certain degree of environmental pollution but also cause a huge waste of resources, making it impossible to effectively utilize the recyclable resources in the discharged mud wastewater, resulting in a high overall operating cost during the actual operation.

[0037] In this embodiment, the top box 102 is fixedly mounted on one side of the base frame 101, and the inlet channel 103 is fixedly mounted on one side of the top box 102. During actual operation, the user can introduce the guided muddy and sewage through the inlet channel 103, so that the muddy and sewage can first be processed by the internal components of the top box 102 and then enter the corresponding mechanism provided inside the base frame 101.

[0038] The separation filter plate 104 is fixedly connected to the top box 102 and is located inside the top box 102. The diverter baffle 105 is rotatably connected to the top box 102 and is located inside the top box 102. The two mounting brackets 106 are respectively fixedly mounted on both sides of the interior of the base frame 101. The two heating cylinders 107 are respectively connected to the two mounting brackets 106 and are located on one side of the corresponding mounting bracket 106.

[0039] The two discharge pipes 108 are respectively installed at the bottom of the two heating cylinders 107, the heating component is connected to the base frame 101, the control component is connected to the base frame 101, the stirring component is connected to the base frame 101, and the sweeping component is connected to the top box 102. The separation filter plate 104 is an inclined filter plate, so that when blocking solid impurities, the impurities can be concentrated at the lowest end of the plate through the inclined setting;

[0040] The separation filter plate 104 is fixedly installed in the top box 102. The separation filter plate 104 can perform preliminary filtration on the muddy sewage introduced by the inlet channel 103, so that solid particles can be separated from the muddy water. The diversion baffle 105 is rotatably installed in the top box 102.

[0041] At the same time, two heating cylinders 107 are provided inside the base frame 101, wherein corresponding electric heating modules are embedded in the side walls of the heating cylinders 107 so as to fully heat the materials in the heating cylinders 107. The tops of the two heating cylinders 107 are connected to the top box 102 through two inlet grooves provided on the base frame 101, and the diverter baffle 105 is provided between the two inlet grooves. When the diverter baffle 105 rotates to the corresponding side;

[0042] The diversion baffle 105 can block the inlet groove on the corresponding side, so that the muddy water filtered by the separation filter plate 104 in the top box 102 enters the corresponding heating cylinder 107 through the developed inlet groove;

[0043] In this way, the continuously introduced muddy water can be diverted and guided by the left and right rotation of the diversion baffle 105, so that the muddy water inside each heating cylinder 107 can be processed independently, avoiding the impact of the subsequent continuously introduced muddy water on the processing of the previously introduced muddy water. The bottom of each heating cylinder 107 is provided with a corresponding discharge pipe 108;

[0044] At the same time, the two heating tubes 107 are mounted on the mounting bracket 106. The mounting bracket 106 is adapted to the guide groove provided between the outer wall of the heating tube 107 through the supporting bosses on both sides, so that the heating tube 107 can slide in a small range on the mounting bracket 106. At the same time, the cooperation between the guide groove on the outer wall of the heating tube 107 and the supporting bosses on both sides of the mounting bracket 106 can prevent the heating tube 107 from rotating due to the stirring of the stirring member.

[0045] Secondly, the heating fan 109 is fixedly connected to the base frame 101 and is located on one side of the base frame 101; the guide channel 110 is connected to the heating fan 109 and is fixedly installed on one side of the base frame 101; the diversion hole column 111 is rotatably connected to the guide channel 110 and is located in the guide channel 110; the derivation component is connected to the base frame 101, and the two derivation channels 115 are set in a one-to-one correspondence with the two heating cylinders 107, and the two derivation channels 115 are fixedly installed on the The two condensing coils 116 are arranged in a one-to-one correspondence with the two derivation channels 115 and the two heating tubes 107, and the two condensing coils 116 are correspondingly connected to the two derivation channels 115 and installed in the base frame 101; the two exhaust pipes 117 are correspondingly connected to the two condensing coils 116 and installed on one side of the base frame 101, and the heating fan 109 is arranged on the back side of the base frame 101, and the air outlet of the heating fan 109 is connected to the guide channel 110;

[0046] The guide channel 110 is provided with three openings in total. The middle opening of the guide channel 110 is connected to the air outlet of the heating fan 109, and the other two openings of the guide channel 110 are respectively provided at the top of the two heating cylinders 107, so that the hot air outputted from the heating fan 109 can be guided through the guide channel 110 to complete the rapid heating of the interior of the corresponding heating cylinder 107.

[0047] The guide channel 110 is provided with a diverter hole column 111 at the middle end thereof. The diverter hole column 111 is provided with interconnected through holes. The through holes provided in the diverter hole column 111 can connect the bottom of the diverter hole column 111 with the area on a designated side of the diverter hole column 111, so that the diverter hole column 111 can function similarly to the diverter baffle 105 and can control the gas guide direction of the guide channel 110 by rotating.

[0048] The outlet channel 115, the condenser coil 116 and the discharge pipe 117 are provided in two groups, one corresponding to each of the two heating tubes 107. The two outlet channels 115 are respectively provided on the top of the two heating tubes 107. The condenser coil 116 connected to each outlet channel 115 is respectively wound around the outside of the corresponding two heating tubes 107. The condenser coil 116 and the heating tube 107 are both made of heat-conducting material.

[0049] It should be noted that the condenser coil 116 and the outlet channel 115 of the same group correspond to two different heating tubes 107 respectively. The outlet channel 115 on the right side corresponds to the heating tube 107 on the right side, and the condenser coil 116 connected to the outlet channel 115 on the right side is wound around the heating tube 107 on the left side, so that the water vapor generated inside the corresponding heating tube 107 can be guided through the outlet channel 115.

[0050] The water vapor is then cooled and liquefied through the condensing coil 116, and finally the liquefied water is discharged through the discharge pipe 117 provided at the end of the condensing coil 116. Since the condensing coil 116 is provided on the outer circle of the heating tube 107, the heat emitted by the liquefaction of the water vapor in the condensing coil 116 can be absorbed by the corresponding heating tube 107, so that when the heating tube 107 on one side evaporates the excess water inside the mud water by heating, the heating tube 107 on the other side can use the heat generated by the liquefaction of the water vapor in the corresponding condensing coil 116 for preheating.

[0051] At the same time, the controller 112 is fixedly connected to the base frame 101 and is located on one side of the base frame 101; the weight sensor 113 is electrically connected to the controller 112 and is fixedly mounted on a side of the mounting bracket 106 close to the heating cylinder 107; the outlet valve 114 is electrically connected to the controller 112 and is mounted on one side of the discharge pipe 108; the driving component is connected to the diverter hole column 111; the linkage component is connected to the diverter baffle 105, the driving shaft 118 is fixedly connected to the diverter hole column 111 and is rotatably mounted on one side of the base frame 101; the output shaft of the driving motor 119 is connected to the driving shaft 118, the driving motor 119 is electrically connected to the controller 112 and is fixedly mounted on one side of the base frame 101;

[0052] The sleeve bevel gear 120 is fixedly connected to the drive shaft 118 and sleeved on the drive shaft 118. The driving shaft 121 is fixedly connected to the diverter baffle 105 and is rotatably mounted on one side of the top box 102. The driving bevel gear 122 is engaged with the sleeve bevel gear 120 and is fixedly mounted on one side of the driving shaft 121. The drive shaft 118 is fixedly connected to the diverter hole column 111 and is fixed to the output shaft of the drive motor 119.

[0053] At the same time, the upper end of the driving shaft 118 is also fixed with the sleeve bevel gear 120, and the sleeve bevel gear 120 is engaged with the driving bevel gear 122 provided on the driving shaft 121. The driving shaft 121 is fixed to the diverter baffle 105. In this way, when the driving motor 119 drives the driving shaft 118 to rotate, the driving shaft 118 can synchronously drive the diverter baffle 105 and the diverter hole column 111 through the cooperation of the sleeve bevel gear 120 and the driving bevel gear 122;

[0054] Since the diverter baffle 105 and the diverter hole column 111 both rotate 180 degrees when performing the conversion guidance of their corresponding mechanisms, the gear parameters of the driving bevel gear 122 and the sleeve bevel gear 120 can be completely consistent, thereby ensuring the consistency of the mud water introduction and the heating gas introduction of the two heating cylinders 107;

[0055] It should be noted that when the diverter baffle 105 blocks the inlet groove connected to the left heating cylinder 107, the diverter hole column 111 can enable the guide channel 110 to guide the hot air into the blocked heating cylinder 107, thereby completing the heating inside the corresponding heating cylinder 107 and evaporating the excess water. The weight sensor 113 is fixedly installed on each of the mounting brackets 106. The weight sensor 113 is arranged between the bottom of the heating cylinder 107 and the top of the mounting bracket 106. The weight sensor 113 is connected to the controller 112 through a corresponding control circuit, so that the user can monitor the weight of the mud and sewage loaded on the two heating cylinders 107 provided inside the chassis 101 through the provided weight sensor 113;

[0056] The controller 112 is also connected to the drive motor 119 via a corresponding control circuit, so that the controller 112 can control the drive motor 119 according to the corresponding weight information fed back by the weight sensor 113, and further control the diverter baffle 105 and the diverter hole column 111 accordingly;

[0057] During actual operation, when the weight of the heating cylinder 107 on one side sensed by the weight sensor 113 exceeds a preset value, the controller 112 can control the driving motor 119 to cause the diverter baffle 105 and the diverter hole column 111 to perform corresponding displacement, so that the muddy water can be diverted to the heating cylinder 107 on the other side, and the interior of the heating cylinder 107 with a weight exceeding the preset value can be heated accordingly;

[0058] The controller 112 is also connected to the outlet valve 114 installed on the discharge pipe 108 through a corresponding circuit. When the heating cylinder 107 loaded with a fixed amount of muddy water is heated, the water inside the muddy water will continue to evaporate, so the total weight of the heating cylinder 107 corresponding to the continuous heating will continue to decrease.

[0059] The user can pre-set the drop value according to the actual operation situation. After the overall weight of the heating cylinder 107 drops within a certain range, the controller 112 can control the corresponding outlet valve 114 to discharge the mud through the information feedback of the weight sensor 113. After the corresponding heating cylinder 107 completes the discharge, the outlet valve 114 is controlled to close, waiting for the heating cylinder 107 on the other side to complete the filling of mud water.

[0060] It should be noted that in the entire control system, the weight in the heating cylinder 107 will continue to increase during the mud feeding process. After the weight rises to a preset value, the drive motor 119 needs to be controlled. When the weight on one side begins to drop, it proves that the heated water in the corresponding heating cylinder 107 is evaporating. Once the weight is detected to have dropped to a specified range, the export valve 114 on the corresponding side needs to be controlled to export. At this time, the weight of the heating cylinder 107 being exported will drop rapidly. The user can pre-set a minimum weight value. Once it drops to the minimum value, the export valve 114 can be controlled to stop opening. It can be seen from the above control logic that the controller 112 will not interfere with the control nodes of the drive motor 119 and the corresponding export valve 114. The corresponding weight information transmitted by the weight sensor 113 can be controlled accordingly, making the entire discharge and the selection of material and gas guide more flexible and quick.

[0061] When the shield machine construction mud and water separation and recycling device of this embodiment is in use, mud and sewage are introduced through the introduction channel 103, and then the solid impurities in the introduced mud and sewage are blocked by the separation filter plate 104 provided in the top box 102, so that the filtered clean mud water can enter the corresponding heating cylinder 107 provided in the base frame 101;

[0062] When the heating cylinder 107 on the corresponding side is continuously filled with clean mud water, the weight sensor 113 below the corresponding heating cylinder 107 will send the detected weight information to the controller 112. When the weight detected by the weight sensor 113 exceeds a preset value, the controller 112 will control the drive motor 119 to rotate the drive shaft 118.

[0063] Then, the bevel gear 120 provided on the driving shaft 118 cooperates with the driving bevel gear 122 on the driving shaft 121 to synchronously drive the diverter baffle 105 and the diverter hole column 111, so that the clean mud water entering the interior of the base frame 101 can be introduced into the heating cylinder 107 on the other side, and the heating cylinder 107 blocked by the diverter baffle 105 can guide the hot air generated by the heating fan 109 through the rotation of the diverter hole column 111, so that the clean mud water inside the blocked heating cylinder 107 can be heated and the excess water can be evaporated;

[0064] At the same time, the water vapor generated by heating can be liquefied and discharged through the corresponding outlet channel 115, the condensation coil 116 and the discharge pipe 117. When the water vapor is liquefied through the condensation coil 116, since the condensation coil 116 is correspondingly arranged with the heating cylinder 107, the heat dissipated by the liquefied water vapor can be used to complete the preheating of the clean mud water inside the corresponding heating cylinder 107, so that resources can be used more reasonably.

[0065] When the clean mud water in the corresponding heating cylinder 107 completes evaporation, the weight sensor 113 can transmit the corresponding weight information monitored to the controller 112 due to the decrease in overall weight, and then the controller 112 controls the export valve 114 according to the data feedback of the weight sensor 113, so that the clean mud and water after separation can be discharged in an orderly manner. After the clean mud in the corresponding heating cylinder 107 is discharged, the controller 112 controls the export valve 114 to close. Once the heating cylinder 107 on the other side completes the introduction of clean mud water, the controller 112 will The drive motor 119 will be controlled again to allow the clean mud water to enter the emptied heating cylinder 107, and the heating cylinder 107 on the other side will be heated and excess water will be discharged after the addition is completed. Such continuous cycle operation can continuously complete the separation and recovery of solid impurities, water and mud in mud wastewater, and realize alternating recovery by adopting two groups of working modules. At the same time, when recycling the mud wastewater, the heat of the separated water vapor is utilized, and then the working module on the designated side is preheated, so that resources can be more fully utilized in the entire recycling process, which greatly improves construction efficiency and economic benefits.

[0066] Second embodiment:

[0067] See also Figures 5 to 7 , Figure 5 This is a schematic diagram of the overall structure of the shield machine construction mud and water separation and recycling device of the second embodiment. Figure 6 Schematic diagram of the installation structure of the rotating shaft 201. Figure 7 This is a schematic diagram of the installation structure of the wall scraping bracket 204. The stirring component provided by the present invention includes a rotating shaft 201, a rotating motor 202, a stirring support rod 203, a wall scraping bracket 204 and a control component. The control component includes a button control panel 205, a guide rail platform 206, a pressing slide 207, a rotating part 208 and a rotating motor 209.

[0068] Among them, the two rotating shafts 201 are arranged in a one-to-one correspondence with the two heating cylinders 107, and the two rotating shafts 201 are rotatably mounted on one side of the base frame 101; the two rotating motors 202 are arranged in a one-to-one correspondence with the two rotating shafts 201, and the output shafts of the rotating motors 202 are connected to the rotating shafts 201, and the rotating motors 202 are fixedly mounted on one side of the base frame 101; the stirring support rods 203 are fixedly connected to the rotating shafts 201 and are located on one side of the rotating shafts 201; the wall scraping bracket 204 is fixedly connected to the rotating shaft 201 and is located on one side of the rotating shaft 201, and the stirring paddles consisting of the two groups of the rotating shafts 201, the stirring support rods 203 and the wall scraping brackets 204 are arranged in a one-to-one correspondence above the two heating cylinders 107;

[0069] At the same time, the two rotating shafts 201 are respectively fixed to the corresponding output shafts of the rotating motor 202 so that they can be driven by the corresponding rotating motor 202. In this way, the mud water inside the heating cylinder 107 can be stirred by driving the stirring paddle composed of the rotating shaft 201, the stirring support rod 203 and the scraper bracket 204 to rotate, so that the mud water is heated more evenly during heating, and the evaporation and discharge efficiency of the clean water in the mud water is improved. At the same time, the side of the scraper bracket 204 is fitted with the inner wall of the heating cylinder 107, so that the mud will not adhere to the inner wall of the cylinder for a long time when the heating cylinder 107 is discharging and stirring and mixing through the rotation of the scraper bracket 204.

[0070] Secondly, there are two button control panels 205, which are electrically connected to the corresponding rotating motors 202 and installed on one side of the base frame 101; the guide rail platform 206 is fixedly connected to the base frame 101 and is located on one side of the base frame 101; the pressing slide 207 is slidably connected to the guide rail platform 206 and is located on the side of the guide rail platform 206 close to the button control panel 205; the rotating member 208 is connected to the pressing slide 207 and is rotatably installed on one side of the base frame 101; the output shaft of the rotating motor 209 is connected to the rotating member 208, and the rotating motor 209 is fixedly installed on one side of the base frame 101. Each rotating motor 202 is controlled by the corresponding button control panel 205;

[0071] When the button on the button control panel 205 is in a pressed state, the rotary motor 202 is powered on and operates; when the button on the button control panel 205 is in a popped-out state, the rotary motor 202 is powered off and stops operating. The pressing slide 207 is L-shaped and is slidably mounted on the side of the chassis 101 in cooperation with the guide rail platform 206. A vertical guide groove is further provided on the outer side of the pressing slide 207 to cooperate with the round table at the end of the rotating member 208. The rotating member 208 is fixed to the output shaft of the rotary motor 209.

[0072] When the rotating motor 209 drives the rotating member 208 to rotate, the frustum at the end of the rotating member 208 can drive the pressing slide 207 to move back and forth left and right by cooperating with the vertical guide groove on the side of the pressing slide 207. The bent part of the pressing slide 207 cooperates with the button control panel 205. When the pressing slide 207 is located above the corresponding button control panel 205, the button on the top of the button control panel 205 will be in a pressed state. In this way, the two button control panels 205 can be pressed at intervals by sliding the pressing slide 207, thereby correspondingly controlling the rotating motors 202 on both sides.

[0073] When the shield machine of this embodiment is used to construct the mud and water separation and recycling device, the mud water inside the heating cylinder 107 can be stirred by the rotating motor 202 in cooperation with the rotating shaft 201 and the scraper bracket 204 and the stirring support rod 203 provided on the rotating shaft 201, so that the mud water inside the heating cylinder 107 is more efficient when heating. At the same time, the rotating motor 209 in cooperation with the rotating part and the pressing slide 207 can press the two button control panels 205 back and forth at intervals, thereby controlling the two rotating motors 202, so that when the rotating motor 202 on one side drives the drive shaft 118 to rotate, the rotating motor 202 on the other side drives the drive shaft 118 to rotate. The rotating motor 202 will not be driven. By adopting the above-mentioned intermittent stirring control, it can be ensured that the two heating tubes 107 will be in a state without the influence of large external forces for a period of time. In this way, the weight sensor 113 can make the data more stable when measuring the internal weight of the heated tube, avoiding the weight data detected by the weight sensor 113 from constantly fluctuating over a large range due to the continuous stirring of the corresponding stirring mechanism. At the same time, the user can also filter the weight data received by the controller 112 through the program, and can extract the weight information of the heating tube 107 detected in a stable state, so that it is more accurate when controlling, which greatly enhances the practicality of the entire device.

In order to facilitate the guidance of solid impurities, the user can set a corresponding guide plate at the position where the solid impurities are discharged in the top box 102 to facilitate the collection of solid impurities.

The pushing screw 306 is fixed to the output shaft of the pushing motor 307, so that when the user needs to clean the solid impurities inside the top box 102, the internal space of the top box 102 can be cut off by moving the intercepting slide 305 downward to avoid the mud and sewage introduced by the inlet channel 103 from splashing out when the solid impurities are discharged through the rotating sealing plate 301 and the connecting sweeping frame 303.

[0078] When the shield machine of this embodiment is used to construct the mud and water separation and recycling device, the intercepting slide 305 can be driven by the pushing motor 307 in cooperation with the pushing screw 306, and then the intercepting slide 305 is used to divide the area above the top box 102, and then the rotating sealing plate 301 is driven to rotate by the control motor 302. The solid impurities accumulated inside the top box 102 are discharged by the rotation of the rotating sealing plate 301 in cooperation with the connecting sweeping frame 303, so that the user can more conveniently and quickly export the solid impurities in the top box 102, which greatly enhances the practicality of the entire device.
