[0029] The double-headed motor 121 is started to drive the two separation screw rods 120 to rotate synchronously. Since the rotation directions of the two separation screw rods 120 are opposite, the two semicircular sealing slides 119 are moved toward each other or away from each other.

[0030] A stirring gear ring 127 is rotatably installed on the mixing cylinder 103, and a stirring motor 129 is also fixedly installed on the outer side of the mixing cylinder 103. A stirring gear 128 is fixedly installed on the output shaft of the stirring motor 129. The stirring gear 128 and the stirring gear ring 127 form a spiral pair. A circular slide 130 is movably provided on the stirring gear ring 127. The circular slide 130 and the mixing cylinder 103 are in sliding cooperation. A circular slide 122 is provided above the circular slide 130. The circular slide 122 and the stirring gear ring 127 are in sliding cooperation. Three stirring straight plates 131 are fixedly provided in a circular array on the adjustment circular plate 132, and the stirring straight plates 131 all slide in cooperation with the circular slide 130.

[0031] The stirring motor 129 is started to drive the stirring gear 128 to rotate, that is, the stirring gear ring 127 is rotated. Since the circular slide 122 and the stirring gear ring 127 are slidingly matched, the circular slide 122, the circular slide 130, and the adjustment circular plate 132 are all rotated synchronously, thereby causing the stirring straight plate 131 to stir the inside of the mixing cylinder 103. The upper end of the mixing cylinder 103 is rotated to be installed with the fan-shaped sealing strip plate 117. When the mixing cylinder 103 and the fan-shaped sealing strip plate 117 are fully engaged, A complete cylinder is formed. When the mixing cylinder 103 and the fan-shaped sealing strip plate 117 are fully engaged, the inner circumferential surfaces of the mixing cylinder 103 and the fan-shaped sealing strip plate 117 are on the same circumference. At this time, the mixing cylinder 103, the semicircular sealing slide plate 119, the fan-shaped sealing strip plate 117, and the circular slide plate 130 are engaged to form a closed mixing chamber. The mixing cylinder 103 is also symmetrically fixed with a fan-shaped heating plate 110, which is used to heat the inside of the mixing cylinder 103.

[0032] A positioning unit is provided between the circular slide 130 and the positioning circular plate 132, and the positioning unit includes a positioning screw rod 123 and a positioning screw rod 2 124. The two ends of the positioning screw rod 123 are respectively rotatably connected to the circular slide 122 and the circular slide 130, the positioning screw rod 123 and the stirring gear ring 127 constitute a spiral pair, the positioning screw rod 2 124 is rotatably connected to the circular slide 130, and a transmission shaft 133 is rotatably installed on the positioning circular plate 132.

[0033] In the initial position, the adjustment circular plate 132 is located at the position farthest from the upper surface of the circular slide 122. At this time, the stirring straight plate 131 is completely located inside the mixing chamber, driving the adjustment screw rod 124 to rotate. Under the action of the torsion spring 1, the adjustment screw rod 124 rotates relative to the transmission shaft 133, thereby causing the transmission shaft 133 to move toward the upper surface of the circular slide 122. The adjustment circular plate 132 moves synchronously, and the three stirring straight plates 131 on the adjustment circular plate 132 move synchronously. The stirring straight plate 131 slides relative to the circular slide 130, and finally the adjusting circular plate 132 moves to the position closest to the upper surface of the circular slide 122. At this time, the lower end surface of the stirring straight plate 131 and the lower surface of the circular slide 130 are on the same plane. At this time, the adjusting screw rod 124 continues to rotate, and the adjusting circular plate 132 cannot continue to move. That is, the torsion spring between the adjusting circular plate 132 and the transmission shaft 133 is compressed, that is, the adjusting screw rod 124 and the transmission shaft 133 rotate synchronously.

[0034] When the positioning circular plate 132 is located at the position closest to the upper surface of the circular slide 122, the positioning screw 123 is driven to rotate, and the positioning screw 123 rotates relative to the stirring gear ring 127. Under the action of the stirring gear ring 127, the circular slide 122, the positioning screw 123, and the circular slide 130 move toward the lower end surface of the mixing cylinder 103. At this time, the stirring straight plate 131 and the positioning circular plate 132 move synchronously toward the lower end surface of the mixing cylinder 103. At this time, the circular slide 130 scrapes and cleans the inner wall of the mixing cylinder 103.

A torsion spring 2 is provided between the circular slide 122 and the transmission pulley 135.

The transmission pulley 135 and the linkage pulley 136 are rotatably connected. A torsion spring 3 is provided between the transmission pulley 135 and the linkage pulley 136. One end of the torsion spring 3 is fixedly connected to the transmission pulley 135, and the other end of the torsion spring 3 is fixedly connected to the linkage pulley 136.

The other end of spring four is fixedly connected to the linkage pulley 136. The elastic force of torsion spring four is always greater than the elastic force of torsion spring three, and the elastic force of torsion spring four is always less than the elastic force of torsion spring one. The axes of adjusting screw rod two 124, transmission pulley 135 and linkage pulley 136 are on the same straight line. A transmission group is provided between the transmission pulley 135 and the adjusting screw rod one 123. The transmission group includes a driven pulley 139 and a transmission belt 141.

A driving pulley 137 is fixedly mounted on the output shaft of the positioning motor 134. A linkage belt 138 is provided between the driving pulley 137 and the linkage pulley 136.

[0036] In the initial position, the torsion springs 1, 2, 3 and 4 are not compressed. At this time, the positioning circular plate 132 is located at the farthest position from the positioning motor 134 .

[0037] The positioning motor 134 is started to drive the driving pulley 137 to rotate. Under the action of the linkage belt 138, the linkage pulley 136 rotates synchronously. Under the action of the torsion spring 4, the positioning screw rod 2 124 and the linkage pulley 136 rotate synchronously. Since the elastic force of the torsion spring 2 is always greater than the elastic force of the torsion spring 3, the linkage pulley 136 rotates relative to the transmission pulley 135. The torsion spring 3 is compressed. Under the action of the positioning screw rod 2 124, the positioning circular plate 132 moves in the direction close to the positioning motor 134, and finally the positioning circular plate 132 moves to the distance from the positioning motor 134. The positioning motor 134 is at its closest position. At this time, the torsion spring three reaches the maximum deformation, the linkage pulley 136 continues to rotate, and the positioning screw rod 2 124 cannot continue to rotate. The linkage pulley 136 rotates relative to the positioning screw rod 2 124. At this time, the transmission pulley 135 and the linkage pulley 136 rotate synchronously, and the torsion spring two is compressed. Under the action of the transmission belt 141, the driven pulley 139 rotates, which makes the positioning screw rod 123 rotate, thereby making the circular slide 122, the circular slide plate 130, the stirring straight plate 131, and the positioning circular plate 132 move downward synchronously.

[0038] An auxiliary unit is provided on the mixing cylinder 103, which is used to adjust the position of the fan-shaped sealing strip 117. The auxiliary unit includes a fan-shaped auxiliary strip 125 and a pressing strip 126. The fan-shaped auxiliary strip 125 is slidably installed on the outside of the mixing cylinder 103, and there is a spring between the fan-shaped auxiliary strip 125 and the mixing cylinder 103. The pressing strip 126 is slidably installed on the circular slide 122, and a spring is provided between the pressing strip 126 and the circular slide 122.

The axis of the bevel gear 2 146 is in the same straight line as the center line of the fan-shaped sealing strip plate 117 and the rotating connection of the mixing cylinder 103. The side of the fan-shaped auxiliary strip plate 125 is fixedly provided with an L The L-shaped side plate 140 and the auxiliary rack 144, the auxiliary rack 144 and the auxiliary gear 143 form a gear rack pair when engaged, the side of the auxiliary gear 143 is fixedly provided with an auxiliary round block 142, the end of the L-shaped side plate 140 is fixedly provided with a limiting strip 155, the auxiliary round block 142 is provided with a sliding groove that cooperates with the limiting strip 155, the limiting strip 155 is used to limit the position of the fan-shaped sealing strip plate 117, a torsion spring five is provided between the fan-shaped sealing strip plate 117 and the mixing cylinder 103, one end of the torsion spring five is fixedly connected to the mixing cylinder 103, and the other end of the torsion spring five is fixedly connected to the fan-shaped sealing strip plate 117.

[0040] When the stirring gear ring 127 rotates, the pressing strip 126 rotates synchronously. Under the action of the fan-shaped auxiliary strip 125 and the pressing strip 126, the fan-shaped auxiliary strip 125 is always located below the pressing strip 126, that is, when the pressing strip 126 rotates to any position, the pressing strip 126 moves downward and can always contact the upper surface of the fan-shaped auxiliary strip 125.

[0041] In the initial position, that is, the positioning circular plate 132 is located at the farthest position from the positioning motor 134, at this time, the pressing strip plate 126 and the fan-shaped auxiliary strip plate 125 are not in contact, and the torsion spring five is not compressed. At this time, the fan-shaped sealing strip plate 117 and the mixing cylinder 103 are in an engaged state, and the springs between the fan-shaped auxiliary strip plate 125 and the mixing cylinder 103, as well as the springs between the pressing strip plate 126 and the stirring gear ring 127 are not compressed. At this time, the slide groove and the limiting strip block 155 on the auxiliary circular block 142 are in an engaged state. Under the action of the limiting strip block 155, the auxiliary circular block 142 cannot rotate freely, that is, the fan-shaped sealing strip plate 117 cannot rotate relative to the mixing cylinder 103, that is, the position of the fan-shaped sealing strip plate 117 is locked, and the auxiliary rack 144 and the auxiliary gear 143 are not in contact.

[0042] When it is necessary to open the fan-shaped sealing strip plate 117 on the mixing cylinder 103, the positioning motor 134 is started to drive the linkage pulley 136 to rotate, and the positioning screw rod 124 rotates. Since the positioning circular plate 132 cannot continue to move downward, the torsion spring 1 between the positioning circular plate 132 and the transmission shaft 133 is compressed, and the pressing strip plate 126 continues to move downward and contacts the upper surface of the fan-shaped auxiliary strip plate 125. The pressing strip plate 126 continues to move downward, and the fan-shaped auxiliary strip plate 125 moves downward synchronously. The springs between the fan-shaped auxiliary strip plate 125 and the mixing cylinder 103 and the springs between the pressing strip plate 126 and the stirring gear ring 127 are all compressed. The L-shaped side plate 140, the auxiliary rack 144, the limiting block 15 on the fan-shaped auxiliary strip plate 125 5 moves downward synchronously, and the limiting strip 155 moves downward relative to the slide groove on the auxiliary round block 142, eventually causing the limiting strip 155 to disengage from the auxiliary round block 142, that is, the limiting strip 155 releases the lock on the position of the sector-shaped sealing strip plate 117, and at this time the auxiliary rack 144 contacts the auxiliary gear 143, and the sector-shaped auxiliary strip plate 125 continues to move downward.

[0046] The sample particles and water to be tested are added to the mixing chamber, and then the mixing chamber is stirred by the stirring straight plate 131, so that the sample particles to be tested and the water are fully mixed in the mixing chamber. Then, a regulator is added to the mixing chamber to make the pH value of the test liquid greater than 12. Then, the fan-shaped heating plate 110 is used to heat the mixing chamber, so that the ammonium ions in the mixed liquid in the mixing chamber are converted into ammonia gas. The evaporated ammonia gas enters the detection chamber along the air guide tube 105, and the air guide tube 10 is controlled by the solenoid valve 106. 5, the switching motor 152 is started to drive the switching circular plate 149 to rotate, that is, the position of the glass cup 150 on the switching circular plate 149 is adjusted so that the required glass cup 150 is moved to just below the end of the air guide tube 105, and then the feeding electric cylinder 148 is started to move the feeding circular plate 147 upward, so that the end of the air guide tube 105 is located inside the solution in the glass cup 150. The glass cup 150 is used to hold the sulfuric acid solution. The sulfuric acid solution in the glass cup 150 absorbs the ammonia discharged from the air guide tube 105. The liquid level of the glass 150 is detected by the camera 151. When the required amount is reached, the electromagnetic valve 106 is closed, and the feed cylinder 148 is started to move the feed circular plate 147 upward. Then, the switching motor 152 is started to drive the switching circular plate 149 to rotate, so that the glass 150 is rotated to the bottom of the end of the second liquid guide tube 116. Then, the indicator liquid in the indicator liquid storage cylinder 111 is added to the glass 150 through the electromagnetic valve 3 114 and the second liquid guide tube 116. Then, the switching circular plate 149 is rotated again. 9, so that the glass 150 is located directly below the end of the first liquid guide tube 115, and then the titrant in the titrant storage tank 112 is dripped into the glass 150 through the second solenoid valve 113 and the first liquid guide tube 115. The color change in the glass 150 is monitored by the camera 151. When the camera 151 detects a color change in the indicator in the glass 150, the addition of the titrant is stopped. Then, based on the volume of the sodium hydroxide standard titrant consumed during the titration, the ammonium ion content in the sample can be calculated.

[0047] The pressure sensor 118 monitors the pressure changes inside the mixing chamber to prevent the mixing chamber from exploding when the second sector housing 107 is opened when the pressure inside the mixing chamber is too high. The interior of the mixing chamber is observed through the curved glass plate 108. When the glass 150 needs to be replaced, the expansion motor 109 is activated to rotate the second sector housing 107, causing it to open. The electromagnet 153 is then turned off, releasing the attraction and fixation of the circular magnet 154, thereby releasing the fixation of the glass 150, making it easier to remove and place the glass 150.

[0048] Working principle: The fan-shaped sealing strip 117 is controlled to open by the auxiliary unit, and then the sample to be tested and water are added into the mixing chamber. Then the fan-shaped sealing strip 117 is closed, and then the stirring motor 129 is started to make the three stirring straight plates 131 mix and stir the sample inside the mixing chamber. In the stirring process, the positioning unit is used to make the stirring straight plates 131 slide relative to the circular slide 130, so that under the action of the circular slide 130, the attachments on the surface of the stirring straight plates 131 are scraped off, and the stirring straight plates 131 move up and down inside the mixing chamber, which can also improve the mixing effect of the sample and water inside the mixing chamber.

[0049] A regulator is then added to the mixing chamber to adjust the pH value of the solution. The solution in the mixing chamber is then distilled via the fan-shaped heating plate 110. Before distillation begins, a specified amount of sulfuric acid solution is added to each of the glass cups 150 on the switching circular plate 149. Ammonia gas is then injected into one of the glass cups 150 via the gas pipe 105. When the camera 151 detects that the liquid level in the glass cup 150 has reached the required amount, the glass cup 150 is first moved below the second liquid pipe 116. An indicator is then added to the glass cup 150 via the second liquid pipe 116. The glass cup 150 is then moved directly below the first liquid pipe 115 for titration. When the camera 151 detects a color change in the indicator in the glass cup 150, the addition of the titration solution is stopped. The ammonium ion content in the sample can then be calculated based on the volume of the sodium hydroxide standard titration solution consumed during the titration.

[0050] By repeating the above steps, the sample can be titrated multiple times using multiple glasses 150, thereby improving the accuracy of the measurement results.

[0051] After the measurement is completed, the double-headed motor 121 is started to move the two semicircular sealing slides 119 to the farthest positions, and the positioning circular plate 132 is first moved to the position closest to the positioning motor 134, and then the circular slide 130, the stirring straight plate 131, and the positioning circular plate 132 are moved upward synchronously, so that the circular slide 130 scrapes and cleans the inside of the mixing cylinder 103, and the residue falls into the waste barrel 102 below. When the lower end surface of the circular slide 130 and the lower end surface of the mixing cylinder 103 are on the same plane, the staff can clean the lower surface of the circular slide 130.

[0052] The present invention is not limited to the above-mentioned specific embodiments. Various modifications made by technicians in the relevant technical field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.
