DETAILED DESCRIPTION

[0027] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0028] REFERENCE Figures 1-6The utility model discloses an alloy production high -efficient energy -conserving sintering furnace, including furnace body 1 and support 11, furnace body 1 fixed mounting is in support 11, be provided with import 12 on furnace body 1, be provided with the closing door for import 12 to carry out the closure on furnace body 1, be provided with the driver for driving closing door rotation on support 11, and the driver drives closing door rotation, when closing door is turned open from furnace body 1, import 12 opens, when closing door is turned to furnace body 1, import 12 closes. Furnace body 1 is equipped with cleaning mechanism, and cleaning mechanism is slidably connected in furnace body 1, and cleaning mechanism is used for cleaning the sundries of furnace body 1 inner wall, and the pushing device (not shown in the drawing) for pushing material and cleaning mechanism into or out of furnace body 1 can be arranged on support 11. When sintering furnace works, open import 12, add the alloy material to be sintered into furnace body 1, carry out sintering processing, when sintering furnace is used, needs to clean the sundries of sintering furnace inner wall, first, add certain concentration cleaning fluid to furnace body 1, after cleaning fluid stays in furnace body 1 for a period of time, to the sundries of furnace body 1 surface basically dissolved, then the sundries not completely dissolved and the suspended solids produced after the sundries decomposition are cleaned through cleaning mechanism, when cleaning, push cleaning mechanism into furnace body 1, and the sundries of furnace body 1 inner wall are cleaned through cleaning mechanism, after cleaning, can remove cleaning mechanism from furnace body 1.

[0029] Referring to Figure 2 、 Figure 3 and Figure 4 , the cleaning mechanism includes: cleaning plates, a replenishment assembly, and a drive assembly. The drive assembly independently drives the two cleaning plates to move within the furnace body 1 and scrape off the sundries attached to the furnace body 1. The replenishment assembly is used to increase the concentration of the cleaning agent in the cleaning fluid between the two cleaning plates when the cleaning plates move to the sundries that have not been completely decomposed, so as to promote the rapid decomposition of the sundries that have not been completely decomposed. After the decomposition of the sundries, the drive assembly continues to push the two cleaning plates to move, thereby cleaning the sundries within the furnace body 1.

[0030] Referring to Figure 2 、 Figure 3 and Figure 4The outer side walls of the two cleaning plates slide along the side walls of the furnace body 1. The two cleaning plates are a first cleaning plate 2 and a second cleaning plate 21. The side facing the inlet 12 is the back side. The first cleaning plate 2 is located in front of the second cleaning plate 21. The driving assembly independently drives the first cleaning plate 2 and the second cleaning plate 21 to move in a direction parallel to the axis of the furnace body 1. The first cleaning plate 2 is provided with a water inlet 211. The water inlet 211 can be provided with a single or multiple water inlets. Preferably, the water inlet 211 is provided with three or four water inlets. The first cleaning plate 2 is in flexible contact with the inner wall of the furnace body 1. The second cleaning plate 21 is in rigid contact with the inner wall of the furnace body 1. The outer circumferential side of the first cleaning plate 2 is provided with an annular gasket. The gasket is made of flexible material. The gasket on the first cleaning plate 2 can be made of rubber material.

[0031] Referring to Figure 2 , Figure 3 and Figure 4 , the driving assembly is used to independently drive the first cleaning plate 2 and the second cleaning plate 21 to reciprocate along the axis of the furnace body 1. When the driving assembly detects an increase in resistance of the second cleaning plate 21, it stops driving the second cleaning plate 21 to move. The driving assembly includes a driving source and a driving screw. Both the driving source and the driving screw are provided with two. The two driving screws are arranged in the furnace body 1. The length direction of the two driving screws is parallel to the axis of the furnace body 1. The two driving screws are respectively connected to the driving source. The two driving sources independently drive the two driving screws to rotate. The two driving screws are respectively and independently screwed with the first cleaning plate 2 and the second cleaning plate 21. The driving screw connected to the first cleaning plate 2 is a first driving screw 3. The driving source driving the first driving screw 3 to rotate is a first driving source. The driving screw connected to the second cleaning plate 21 is a second driving screw 31. The driving source driving the second driving screw 31 to rotate is a second driving source. The first driving source and the second driving source can be directly selected as a motor. The first driving source and the second driving source are not shown in the figure. The driving end of the second driving source driving the second cleaning plate 21 is provided with a torque sensor. The torque sensor is specifically installed between the output shaft of the second driving source and the second driving screw 31. The torque sensor is used to monitor and record the torque change of the driving shaft on the second driving source in real time.

[0032] Referring to Figure 2 , Figure 3 and Figure 4The control system is used for controlling the working states of the first driving source and the second driving source, and the torsion sensor converts the monitoring data into an electrical signal and outputs the electrical signal to the control system. When the second cleaning plate 21 moves to contact the sundries, the sundries block the movement of the second cleaning plate 21, so that the movement of the second cleaning plate 21 is hindered, and the torque on the driving shaft of the second driving source is also increased accordingly. After the data is transmitted to the control system by the torsion sensor, the control system controls the second driving source to stop working. Since the first cleaning plate 2 continuously moves forward, the distance between the first cleaning plate 2 and the second cleaning plate 21 gradually increases. The first cleaning plate 2 and the second cleaning plate 21 are connected through the adjusting rod 22. After the second cleaning plate 21 stops moving, the first cleaning plate 2 continues to move forward for a certain distance and then stops moving. When the distance between the first cleaning plate 2 and the second cleaning plate 21 increases, the cleaning liquid in the furnace body 1 enters the gap between the first cleaning plate 2 and the second cleaning plate 21 through the water inlet 211 on the first cleaning plate 2, and the replenishing assembly releases the cleaning agent to the gap between the first cleaning plate 2 and the second cleaning plate 21, so as to increase the concentration of the cleaning agent in the cleaning liquid between the first cleaning plate 2 and the second cleaning plate 21, and quickly decompose the sundries between the first cleaning plate 2 and the second cleaning plate 21. After the first cleaning plate 2 and the second cleaning plate 21 are stationary for a certain period of time, the control system drives the second driving source to rotate again.

[0033] With reference to Figure 2 , Figure 3 and Figure 4 , if the monitoring data of the torsion sensor is normal, it indicates that the sundries between the first cleaning plate 2 and the second cleaning plate 21 have been completely decomposed within the time period. If the data of the torsion sensor is still abnormal, it indicates that the sundries between the first cleaning plate 2 and the second cleaning plate 21 have not been completely decomposed, and the control system continues to control the first driving source and the second driving source to stop for a period of time, so as to sufficiently dissolve the sundries. After the sundries are sufficiently dissolved, the second driving source drives the second cleaning plate 21 to move close to the first cleaning plate 2, until the first cleaning plate 2 and the second cleaning plate 21 are reattached, and the cleaning liquid between the first cleaning plate 2 and the second cleaning plate 21 is discharged into the furnace body 1. In order to facilitate the discharge of the cleaning liquid in the first cleaning plate 2 and the second cleaning plate 21, a plurality of water outlets 212 are arranged on the upper side of the first cleaning plate 2. When the second cleaning plate 21 moves close to the first cleaning plate 2, the cleaning liquid between the first cleaning plate 2 and the second cleaning plate 21 is squeezed to flow from the water outlets 212 of the first cleaning plate 2 to the furnace body 1. After the second cleaning plate 21 and the first cleaning plate 2 are attached, the control system controls the first driving source and the second driving source to rotate synchronously, so that the first cleaning plate 2 and the second cleaning plate 21 continuously move forward in the attached state, until the sundries that have not been completely decomposed are encountered again, and the above-mentioned sundry removing operation is repeated.

[0034] With reference to Figure 2 , Figure 3 and Figure 4The adjusting rod 22 for connecting the first cleaning plate 2 and the second cleaning plate 21 is in the shape of a round rod, one end of the adjusting rod 22 is fixed with the second cleaning plate 21, the other end of the adjusting rod 22 passes through the water inlet 211 of the first cleaning plate 2 and is movably connected with the first cleaning plate 2, the number of the adjusting rod 22 is consistent with the number of the water inlet 211, the diameter of the end of the adjusting rod 22 passing through the water inlet 211 is reduced, the end of the adjusting rod 22 passing through the water inlet 211 is fixed with a blocking block 221 on the front side thereof, the diameter of the blocking block 221 is greater than the diameter of the water inlet 211, the diameter of the large end of the adjusting rod 22 is consistent with the diameter of the water inlet 211, the diameter of the small end of the adjusting rod 22 is smaller than the diameter of the water inlet 211, when the first cleaning plate 2 is attached to the second cleaning plate 21, the large end of the adjusting rod 22 extends into the water inlet 211, when the first cleaning plate 2 gradually moves away from the second cleaning plate 21, the small end of the adjusting rod 22 gradually extends into the water inlet 211, and the cleaning liquid in the furnace body 1 enters the first cleaning plate 2 and the second cleaning plate 21 from the gap between the water inlet 211 and the adjusting rod 22.

[0035] With reference to Figure 3 , Figure 4 and Figure 5 Figure 4 Figure 5 Figure 6 , the supplementary assembly is used to release cleaning agent to the gap between the first cleaning plate 2 and the second cleaning plate 21 when the first cleaning plate 2 and the second cleaning plate 21 are separated, so that the content of the cleaning agent between the first cleaning plate 2 and the second cleaning plate 21 is greater than the content of the cleaning agent in the furnace body 1; the supplementary assembly comprises a storage box 4 and a discharging block 41, the storage box 4 is used to store the cleaning agent, the storage box 4 is installed on the end face of the second cleaning plate 21, the lower end of the storage box 4 is provided with a containing groove 42 for placing the discharging block 41, the discharging block 41 slides against the side wall of the containing groove 42, the side wall of the containing groove 42 is provided with a communication port, the communication port is in communication with the inside of the storage box 4, the discharging block 41 forms a cavity, the upper side of the discharging block 41 is provided with an inlet 411, the lower side of the discharging block 41 is provided with an outlet 412, the inlet 411 and the outlet 412 are both in communication with the cavity in the discharging block 41, the discharging block 41 is fixedly connected with the first cleaning plate 2, and the discharging block 41 is slidably connected with the second cleaning plate 21, when the first cleaning plate 2 is attached to the second cleaning plate 21, the communication port is opposite to the inlet 411, when the first cleaning plate 2 pulls the discharging block 41 to separate from the storage box 4, the inlet 411 and the outlet 412 are both in communication with the cavity between the first cleaning plate 2 and the second cleaning plate 21.

[0036] When the first cleaning plate 2 is attached to the second cleaning plate 21, the communication port of the storage box 4 is communicated with the feeding port 411 of the discharging block 41, and the cleaning agent in the storage box 4 enters the discharging block 41 through the communication port; at this time, the discharging port 412 of the discharging block 41 is blocked by the side wall of the accommodating groove 42, so that when the first cleaning plate 2 is attached to the second cleaning plate 21, the cleaning agent in the storage box 4 enters the discharging block 41 partially and is temporarily stored in the discharging block 41; when the first cleaning plate 2 is away from the second cleaning plate 21, the discharging block 41 is pulled out of the accommodating groove 42, the feeding port 411 is misaligned with the communication port, and the side wall of the discharging block 41 blocks the communication port to prevent the cleaning agent in the storage box 4 from flowing out of the communication port; at the same time, the discharging port 412 gradually extends out of the accommodating groove 42 and is opposite to the cavity between the first cleaning plate 2 and the second cleaning plate 21, and the cleaning agent temporarily stored in the discharging block 41 enters the cavity between the first cleaning plate 2 and the second cleaning plate 21 through the discharging port 412 to increase the concentration of the cleaning agent in the cleaning liquid between the first cleaning plate 2 and the second cleaning plate 21; wherein the supplement assembly can be single or multiple groups, and in the embodiment, the supplement assembly is preferably provided with two groups.

[0037] The implementation principle of the high-efficiency energy-saving sintering furnace for alloy production is as follows: when the sintering furnace is working, the inlet 12 is opened, the alloy material to be sintered is added into the furnace body 1, and sintering processing is performed; when the sintering furnace is used up and the sundries on the inner wall of the sintering furnace need to be cleaned, first, a cleaning liquid with a certain concentration is added into the furnace body 1, the cleaning liquid stays in the furnace body 1 for a period of time, and then the sundries that are not completely dissolved and the suspended matters generated after the sundries are decomposed are cleaned through the cleaning mechanism, When cleaning, the cleaning mechanism is pushed into the furnace body 1, the driving assembly drives the first cleaning plate 2 and the second cleaning plate 21 to move along the axial direction of the furnace body 1, and the sundries on the inner wall of the furnace body 1 are scraped off; when the second cleaning plate 21 moves to contact the sundries, the sundries block the movement of the second cleaning plate 21, so that the movement of the second cleaning plate 21 is hindered, and the torque on the driving shaft of the second driving source also increases accordingly; after the data is transmitted to the control system by the torque sensor, the control system controls the second driving source to stop working; because the first cleaning plate 2 continues to move forward, the distance between the first cleaning plate 2 and the second cleaning plate 21 gradually increases; the first cleaning plate 2 and the second cleaning plate 21 are connected through the adjusting rod 22; after the second cleaning plate 21 stops moving, the first cleaning plate 2 continues to move forward for a certain distance and then stops moving; when the distance between the first cleaning plate 2 and the second cleaning plate 21 increases, the cleaning liquid in the furnace body 1 enters the gap between the first cleaning plate 2 and the second cleaning plate 21 through the water inlet 211 on the first cleaning plate 2, and the replenishing assembly releases the cleaning agent to the gap between the first cleaning plate 2 and the second cleaning plate 21, so as to increase the concentration of the cleaning agent in the cleaning liquid between the first cleaning plate 2 and the second cleaning plate 21, and quickly decompose the sundries between the first cleaning plate 2 and the second cleaning plate 21; after the first cleaning plate 2 and the second cleaning plate 21 are static for a certain period of time, the control system drives the second driving source to rotate again. When the first cleaning plate 2 moves away from the second cleaning plate 21, the discharge block 41 is pulled out of the containing groove 42, the feeding port 411 is dislocated from the communication port, the side wall of the discharge block 41 blocks the communication port, the cleaning agent in the storage box 4 is prevented from flowing out of the communication port, the discharge port 412 gradually extends out of the containing groove 42 and is opposite to the cavity between the first cleaning plate 2 and the second cleaning plate 21, and the cleaning agent temporarily stored between the discharge blocks 41 enters the cavity between the first cleaning plate 2 and the second cleaning plate 21 through the discharge port 412, so as to increase the concentration of the cleaning agent in the cleaning liquid between the first cleaning plate 2 and the second cleaning plate 21.
