DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] like Figure 1-4 As shown, the square box 1 has openings at the top and bottom, wastewater enters from the lower opening and overflows from the upper opening, multiple layers of heat exchange components 2 are vertically arranged in the box 1, and the lower water-facing surface of each layer of heat exchange components 2 is installed with a first temperature sensor 3, and the heat exchange component 2 is composed of two liquid inlet pipes 21 and liquid outlet pipes 22 parallelly distributed on the symmetrical side of the box 1, and a number of straight pipes 23 are evenly connected between the liquid inlet pipes 21 and the liquid outlet pipes 22, and the inlet pipes 4 and the outlet pipes 5 are arranged outside the box 1, each liquid inlet pipe 21 is connected to the inlet pipe 4, and each liquid outlet pipe 22 is connected to the outlet pipe 5 through a one-way valve 8, and the output end of the liquid pump is connected to the inlet pipe 4;

[0033] like Figure 5-6 As shown, a first inner tube 25 is adapted and rotatably installed inside the liquid inlet tube 21, and a plurality of groups of axially arranged first liquid holes 26 are distributed annularly on the surface of the first inner tube 25, and the number of the first liquid holes 26 in each group increases gradually. The output shaft of the first motor is connected to the first inner tube 25, and the first temperature sensor 3 is connected to the first motor through a controller;

[0034] Wastewater is conducted from bottom to top in the box body 1 and passes through the gaps of the straight pipes 23. The wastewater temperature is monitored by the first temperature sensor 3, and the monitored temperature information is fed back to the controller. If the temperature is high, all the straight pipes 23 are kept connected, and the liquid pump is turned on to introduce the heat exchange medium from the inlet pipe 4 into the liquid inlet pipe 21, and then conducted to the liquid outlet pipe 22 through each straight pipe 23. The heat exchange medium absorbs the heat of the wastewater when passing through the straight pipe 23, and then is concentratedly discharged by the outlet pipe 5 for secondary utilization. If the temperature of the wastewater monitored by the first temperature sensor 3 drops by one interval, the controller turns on the first motor to drive the first inner pipe 25 to rotate, replaces the first liquid holes 26 with a smaller number to align the straight pipes 23, reduces the conduction amount of the straight pipes 23, and improves the heat absorption rate of the heat exchange medium. Multiple groups of first liquid holes 26 with decreasing numbers are adapted to wastewater in different temperature ranges, and reasonable energy consumption control is achieved.

[0035] The straight tubes 23 of each group of heat exchange components 2 are staggered and distributed, which has a disturbing effect on the conduction of wastewater and realizes uniform heat exchange.

[0036] As the conductance of the straight pipe 23 changes, the pressure intensity and flow rate of the heat exchange medium will be affected. In order to keep the heat exchange medium at a stable flow rate and hydraulic strength for stable heat absorption, it is necessary to adjust the liquid supply intensity of the liquid pump, as follows:

[0037] like Figure 4 , 9As shown, the inlet pipe 4 is connected to a pressure-sensing component 6, which includes an external through-tube 61, which is connected to the inlet pipe 4, and a sliding plug 62 is installed inside the external through-tube 61 through a spring elastic sliding adapter, and a packaging shell 63 is penetrated through the surface of the outer cylinder shell through a wire groove 66, and two second micro switches 64 are symmetrically arranged in the packaging shell 63, and the second micro switches 64 are connected to the liquid pump through the controller, and a touch handle 65 is fixed to the sliding plug 62, and the touch handle 65 passes through the wire groove 66 and is placed between the two second micro switches 64;

[0038] The sliding seal of the sliding plug 62 keeps the same pressure strength in the outer tube 61, the introduction tube 4 and the liquid inlet tube 21. As the conduction amount of the straight tube 23 changes, the hydraulic strength in the liquid inlet tube 21 and the introduction tube 4 changes, which causes the pressure strength in the outer tube 61 to change, prompting the sliding plug 62 to move. When the pressure increases, the sliding plug 62 overcomes the elastic force and drives the touch handle 65 to slide outward, so that the touch handle 65 moves to touch the second micro switch 64 on the outside. The second micro switch 64 on the outside transmits a signal to the controller, and the controller controls the liquid pump to reduce the speed and reduce the liquid supply strength, so that the hydraulic strength in the introduction tube 4 and the liquid inlet tube 21 is reduced. The sliding plug 62 is gradually moved back by the elastic force, so that the touch handle 65 is again kept between the two second micro switches 64.

[0039] When the pressure in the inlet pipe 4 and the liquid inlet pipe 21 decreases, the pressure in the external tube 61 also decreases, and the elastic force causes the sliding plug 62 to drive the touch handle 65 to move inward, and the second micro switch 64 on the inside is touched. The controller controls the liquid pump to increase the speed and improve the liquid supply intensity, so that the pressure in the inlet pipe 4 and the liquid inlet pipe 21 increases, and the sliding plug 62 drives the touch handle 65 to move back, so that the touch handle 65 is maintained between the two second micro switches 64 again, thereby realizing constant pressure delivery of the heat exchange medium, so that the medium has a relatively stable flow rate and the heat exchange effect is relatively stable.

[0040] The second micro switch 64 is rotatably connected to a stud 67, which is threaded through the packaging shell 63. The position of the second micro switch 64 is adjusted by rotating the stud 67 to change the pressure intensity when the touch handle 65 touches the second micro switch 64, thereby adjusting the pressure control.

[0041] In order to improve the heat exchange effect, the conduction path length of the heat exchange medium can also be increased, as follows:

[0042] like Figure 5 , 7As shown, each straight tube 23 is correspondingly provided with a curved tube 24, one end of the curved tube 24 close to the liquid inlet tube 21 is directly connected with the straight tube 23, and the other end of the curved tube 24 is staggered with the straight tube 23 and connected with the liquid outlet tube 22, and the second inner tube 27 is rotatably adapted to be installed inside the liquid outlet tube 22, and a row of axially arranged second liquid holes 28 are provided on the surface of the second inner tube 27, and the second inner tube 27 is transmission-connected with a second motor, and a second temperature sensor 9 is provided at the upper opening of the box body 1, and a third temperature sensor 91 is provided in the outlet tube 5, and the second temperature sensor 9 and the third temperature sensor 91 are connected to the second motor through a controller;

[0043] The temperature of the wastewater after heat exchange is monitored by the second temperature sensor 9, and the temperature of the heat exchange medium after heat exchange is monitored by the third temperature sensor 91. The second temperature sensor 9 and the third temperature sensor 91 feed back the monitored temperature to the controller for comparison. If the difference between the value monitored by the second temperature sensor 9 and the value monitored by the third temperature sensor 91 is greater than the set value, it means that the heat exchange is insufficient. The controller turns on the second motor to drive the second inner tube 27 to rotate, so that the port of the straight tube 23 is blocked, and the port of the curved tube 24 is aligned with the second liquid hole 28 and opened, and the heat exchange medium is conducted through the curved tube 24. The curved tube 24 has a larger heat exchange area and a longer heat exchange path than the straight tube 23, thereby improving the heat exchange effect.

[0044] In order to make the rotation angle of the first inner tube 25 and the second inner tube 27 more accurate, positioning components 7 are provided at the ends of the liquid inlet tube 21 and the liquid outlet tube 22. The specific principle is as follows:

[0045] like Figure 5 , 8 As shown, the positioning assembly 7 includes a sleeve shell 71, which is fixed to the liquid inlet pipe 21 and the liquid outlet pipe 22. A shaft column 72 is rotatably installed in the sleeve shell 71. The output shaft of the first motor is connected to the first inner pipe 25 through the shaft column 72, and the output shaft of the second motor is connected to the second inner pipe 27 through the shaft column 72. A telescopic groove 73 is provided on the surface of the shaft column 72. An arc-shaped protruding handle 74 is provided in the telescopic groove 73 through radial elastic sliding of a spring. A plurality of arc-shaped grooves 75 are provided on the inner wall of the sleeve shell 71. The distribution angle of the arc-shaped groove 75 at the end of the liquid inlet pipe 21 is aligned with the distribution angle of the first liquid hole 26, and the distribution angle of the arc-shaped groove 75 at the end of the liquid outlet pipe 22 is aligned with the penetration angle of the straight pipe 23 and the curved pipe 24. A first micro switch 76 is provided in the arc-shaped groove 75. The first micro switch 76 is connected to the first motor and the second motor through a controller. The arc-shaped protruding handle 74 is inserted into the arc-shaped groove 75 to resist the first micro switch 76.

[0046] Due to the distribution of the first micro switch 76 and the first liquid hole 26 and the one-to-one alignment of the straight tube 23, the curved tube 24 and the liquid outlet tube 22, when the first motor drives the first inner tube 25 to rotate and adjust and the second motor drives the second inner tube 27 to rotate and adjust, when the arc-shaped protruding handle 74 touches the corresponding first micro switch 76, the controller receives the position information and stops adjusting. At this time, the arc-shaped protruding handle 74 is inserted into the corresponding arc-shaped groove 75 to maintain the precise position adjustment of the first inner tube 25 and the second inner tube 27.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
