[0025] The vacuum pump 21 extracts the gas in the condenser 19 to form a negative pressure. The condenser 19 can extract the ammonia and other gases produced by the reaction in the reaction tank 46 through the first delivery pipe 15 and extract the mixed gas such as ammonia and steam in the steam treatment tank through the second delivery pipe 18.

[0026] The first stirring member includes a first driving motor 13, a first auxiliary frame 6, a first rotating shaft 4 and a first spiral blade 5. The first driving motor 13 is installed on the reaction tank 46. One end of the first rotating shaft 4 is transmission-connected to the first driving motor 13, and the other end is inserted into the reaction tank 46 and penetrates the first auxiliary frame 6 to be connected with the first spiral blade 5.

[0027] The first auxiliary frame 6 is provided with a first support 6, and the first rotating shaft 4 passes through the first support 6 and is rotatably connected with the first support 6.

[0028] like Figure 1 and 2 As shown, the number of first auxiliary racks installed can be 1 or 2. When two are installed, the two first auxiliary racks are installed in the reaction tank 46 at intervals.

The first rotating shaft can stably rotate in the reaction tank under the support of the first auxiliary rack.

[0029] The first stirring member can stir the materials in the reaction tank so that the materials are mixed evenly.

[0030] Working mode of the first stirring element:

[0031] Material mixing: The first drive motor 13 starts to work, drives the first rotating shaft 4 to rotate counterclockwise, drives the first spiral blade to rotate counterclockwise, and the first spiral blade drives the electrolytic manganese slag and quicklime mixed materials in the reaction tank to be lifted upward, so as to realize the movement of the electrolytic manganese slag and quicklime mixed materials in the reaction tank, so that the electrolytic manganese slag and quicklime are evenly mixed, promote the maximum reaction of the electrolytic manganese slag and quicklime, and effectively degrade the ammonia nitrogen content in the electrolytic manganese slag.

[0032] Discharging: When the remaining reaction materials in the reaction tank need to be discharged, the first discharging valve is opened, the first driving motor drives the first rotating shaft to rotate clockwise, and the first spiral blade pushes the remaining reaction materials downward to be discharged through the first discharging valve.

The second support 44 may be provided with a rolling bearing, and the second support 44 and the second rotating shaft 37 are rotatably connected through the rolling bearing.

[0035] like Figure 1 and 3As shown, the number of second auxiliary racks installed can be 1 or 2. When two are installed, the two second auxiliary racks are installed in the steam treatment tank 45 at intervals. It should be noted that the two second auxiliary racks do not hinder the rotation of the second spiral plate. It is understandable that the second spiral plate is discontinuous at the second auxiliary rack installed in the middle of the steam treatment tank. The second rotating shaft can stably rotate in the steam treatment tank under the support of the second auxiliary rack.

[0036] The second stirring member can stir the reaction residual material in the steam treatment tank 45, so that the reaction residual material can be evenly contacted with the steam sprayed from the steam interlayer through the multiple through holes on the partition, so that the reaction residual material is evenly heated.

[0037] Working mode of the second stirring element:

[0038] Material stirring: The second drive motor 41 drives the second shaft 37 to rotate counterclockwise, and the second shaft 37 drives the second spiral blade to rotate counterclockwise, driving the material in the steam treatment tank to circulate and move upward, so that the material is evenly contacted with the steam, thereby giving the material uniform heating and achieving steam harmless treatment.

[0039] It should be noted that the electrolytic manganese slag is granular electrolytic manganese slag. The quicklime can be powder.

[0040] In some embodiments of the present disclosure, a structure of a feed member is provided. The feed member includes a first feed pipe 7 and a hopper 8. The first feed pipe 7 is provided with a feed valve 9, which is obliquely installed on the reaction tank 46; the hopper 8 is connected to the first feed pipe 7; wherein the feed valve 9 is electrically connected to the controller 32.

[0041] The first guide pipe 7 is obliquely installed on the reaction tank 46 to facilitate the delivery of electrolytic manganese slag and quicklime into the reaction tank.

[0042] The hopper is used to store the electrolytic manganese slag and quicklime fed into the reaction tank.

[0043] The controller can control the operation of the feed valve.

[0044] How the feed piece works:

[0045] Electrolytic manganese slag or quicklime is placed in the hopper 8, and the feed valve 9 is opened by the controller 32, so that the electrolytic manganese slag or quicklime falls from the hopper 8 into the first material guide pipe 7, and then is guided into the reaction tank 46 through the first material guide pipe 7.

[0046] After the feeding is completed, the controller controls the feed valve 9 to close and controls the first stirring member to work. The first stirring member stirs the electrolytic manganese slag particles and quicklime in the reaction tank to mix them, so that the electrolytic manganese slag and quicklime are evenly mixed, promoting the full reaction of the electrolytic manganese slag and quicklime to maximize the production of ammonia.

[0047] In some embodiments of the present disclosure, a structure of a material guide is provided. Figure 1 As shown, the material guide member includes a first discharge hopper 2 and a second material guide pipe 3. One end of the first discharge hopper 2 is connected to the first discharge valve 43; one end of the second material guide pipe 3 is connected to the steam treatment tank 45, and the other end is connected to the other end of the first discharge hopper 2.

[0048] The first discharge hopper 2 is used to collect the reactants remaining after the reaction in the reaction tank discharged from the first discharge valve 43 , and then discharge them into the second guide pipe 3 through the first discharge hopper, and the second guide pipe 3 then guides the reactants to the steam treatment tank 45 .

[0049] In some embodiments of the present disclosure, a connection structure between an air pump and an acid water tank is provided, and an air supply pipe 26 and a check valve 25 are additionally installed. Figure 1 and 2 As shown, one end of the air supply pipe 26 is connected to the air pump 21 , and the other end extends into the acid water tank 28 , and the check valve 25 is installed on the air supply pipe 26 .

[0050] The check valve can prevent the acid water in the acid water tank from flowing back into the vacuum pump through the air supply pipe.

[0051] In some embodiments of the present disclosure, a control discharge structure on an ammonia water tank is provided, and a first discharge valve 22 and a second discharge valve 27 are additionally installed. Figure 1 and 2 As shown, the first discharge valve 22 is installed on the guide pipe 42 , and the second discharge valve 27 is installed on the discharge port of the ammonia water tank 24 .

[0052] In some embodiments of the present disclosure, in order to facilitate the acquisition of the liquid level height of the ammonia water tank, a liquid level sensor 23 is additionally installed. Figure 1 and 2 As shown, the liquid level sensor 23 is installed on the ammonia water tank 24. The liquid level sensor 23 is electrically connected to the controller 32, and the liquid level data information monitored by the liquid level sensor 23 in the ammonia water tank is transmitted to the controller 32 in real time. The controller 32 has a touch screen, and the liquid level data information monitored by the liquid level sensor is transmitted to the controller, and the controller then displays the corresponding liquid level data information through the touch screen.

[0053] In some embodiments of the present disclosure, a second discharge hopper 33 is additionally installed. Figure 1 and 3 As shown, the second discharge hopper 33 is connected to the second discharge valve 34 .

[0054] The second discharge hopper is in an inverted cone structure, which can be convenient for collecting the residual reaction materials discharged by the second discharge valve for unified discharge.

[0055] In some embodiments of the present disclosure, in order to facilitate water replenishment to the reaction tank, a water pipe 11, a water valve 12 and a nozzle 10 are additionally installed. Figure 1 and 2 As shown, the water delivery pipe 11 is installed with a water valve 12 and is inserted into the reaction tank 46 and connected to the nozzle 10 .

[0056] Working method:

[0057] When water needs to be added to the reaction tank, the water valve 12 is opened, and the water in the water pipe 11 is sprayed into the reaction tank through the nozzle 10.

[0058] The nozzle sprays in an atomized form. It is understandable that when replenishing water, the vacuum pump does not extract the gas in the reaction tank.

[0059] According to the above embodiments, the working mode of the utility model is as follows:

[0060] The controller 32 controls the feeding piece to be opened, and the electrolytic manganese slag particles and quicklime can be respectively put into the reaction tank 46. After the electrolytic manganese slag particles and quicklime are fed, the feeding piece is closed by controlling the controller.

[0061] The controller 32 controls the first drive motor 13 to start working, drives the first rotating shaft 4 to rotate counterclockwise, drives the first spiral blade to rotate counterclockwise, and the first spiral blade drives the electrolytic manganese slag particles and quicklime mixed materials in the reaction tank to be lifted upward, realizes the movement of the electrolytic manganese slag particles and quicklime mixed materials in the reaction tank 46, makes the electrolytic manganese slag and granular quicklime mixed evenly, promotes the maximum reaction of the electrolytic manganese slag and quicklime, can effectively reduce the amount of ammonia nitrogen in the electrolytic manganese slag, and produces the maximum amount of ammonia gas.

[0062] The controller starts the vacuum pump 21 and opens the first control valve 14. The vacuum pump 21 extracts the gas in the condenser 19 through the vacuum pipe 20 to generate negative pressure, so that the condenser 19 extracts the mixed gas such as ammonia in the reaction tank 46 through the first delivery pipe 15. The mixed body enters the condenser 19 through the first delivery pipe 15. The condenser 19 condenses the mixed gas entering, and the ammonia is condensed into ammonia water, which is introduced into the ammonia water tank 24 for storage through the guide pipe 42. The remaining gas enters the vacuum pump through the condenser, and is then transported to the acid water tank 28 by the vacuum pump. The acid water tank can remove the small amount of residual ammonia to prevent the ammonia from being discharged into the atmosphere and causing air pollution.

[0063] Unloading is performed after the reaction is completed: when the remaining reaction materials obtained from the reaction in the reaction tank need to be discharged, the first unloading valve 43 is opened, the first driving motor 13 drives the first rotating shaft 4 to rotate clockwise, and the first spiral blade 5 pushes the remaining reaction materials downward to be discharged through the first unloading valve 43, fall into the first unloading hopper 2, and enter the steam treatment tank 46 through the second material guide pipe 3.

[0064] After the reaction tank is unloaded, the controller controls the first drive motor 13 to stop working, the first discharge valve 43 and the first control valve 14 are closed, and the controller 32 controls the second control valve 36 and the steam valve 31 to open and the second drive motor 41 to start. The second drive motor 41 drives the second shaft 37 to rotate counterclockwise, and the second shaft 37 drives the second spiral blade 38 to rotate counterclockwise. The second spiral blade 38 pushes the reaction residual material from the bottom of the steam treatment tank to the top of the circulation, so that the reaction residual material is effectively in contact with the steam sprayed from the partition 39, so that the reaction residual material is evenly heated. The temperature of the steam can be 150-220°C, and the steam treatment time can be 2-8 hours. The mixed gas in the steam treatment tank 45 enters the air inlet pipe 17 through the second conveying pipe 18 and the second control valve 36, and then enters the condenser 19 through the air inlet pipe 17. The first discharge valve 22 is opened, and the condensed liquid generated in the condenser enters the ammonia tank 24 for storage through the guide pipe 42 and the first discharge valve 22.

[0065] After the processing time reaches the set steam processing time, the steam valve 31 and the second control valve 36 are closed through the controller 332, the vacuum pump 21 is stopped, the second discharge valve 35 is opened, the second drive motor 41 is reversed, and the second spiral blade rotates clockwise to push the harmless electrolytic manganese slag obtained by the steam treatment tank to the second discharge valve 35, and the slag falls into the second discharge hopper 33 through the second discharge valve 35 for discharge.

[0066] After the unloading of the steam treatment tank is completed, the controller 32 controls the second driving motor 41 to stop working and the second unloading valve 34 to close.

[0067] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
