It is a white crystal and one of the simplest organic compounds. Urea is the main nitrogen-containing end product of protein metabolism and decomposition in mammals and some fish.

[0003] The main application of urea in thermal power plants is as a reducing agent in the Selective Catalytic Reduction (SCR) denitrification technology. SCR technology is a widely used flue gas denitrification technology that reduces nitrogen oxides (NOx) into nitrogen and water under the action of a catalyst, thereby reducing nitrogen oxide emissions in the atmosphere.

[0004] However, the existing dissolving tank for preparing urea solution has some shortcomings during use. When receiving materials, the staff needs to place the collection bucket under the discharge port. In order to prevent the initial bucket from shifting due to the impact of material discharge, the staff needs to support the receiving bucket with their hands until enough urea solution is collected and the bucket stops shifting before they can release their hands. Such operation is not only time-consuming but also laborious.

[0005] To solve this problem, we proposed an improved urea solution storage tank. The design of this new storage tank is to simplify the material receiving process and reduce the labor intensity of the staff. Summary of the invention

DETAILED DESCRIPTION

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0041] Example 1

[0042] Reference Figure 1~Figure 4 , which is the first embodiment of the present invention, and provides a mobile storage tank for urea solution for a thermal power plant, which includes a storage assembly 100, including a tank body 101, a protective shell 102 arranged on the outer wall of the tank body 101, an interception plate 102a arranged on the end surface of the protective shell 102, and a blocking member 103 arranged on the inner wall of the tank body 101;

[0043] The moving assembly 200 includes a tray 201, a moving wheel 202 arranged at the bottom of the tray 201, a moving block 203 arranged on the outer wall of the tray 201, a first inclined surface 203a arranged on the outer wall of the moving block 203, a second inclined surface 203b arranged on the outer wall on the other side of the moving block 203 and a first sliding groove 203c arranged on the surface of the moving block 203.

[0044] Among them, the tank body 101 is divided into two parts, one part is a cylindrical tube structure with a closed lower end and an open upper end, and the other part is a semicircular spherical cap; the shape of the protective shell 102 is also a semicircular spherical cap, and four interception plates 102a are fixedly installed on the lower surface of the protective shell 102, and the protective shell 102 and the interception plates 102a together constitute a protection for the tank body 101; at the same time, a blocking piece 103 is installed at the upper end surface of the tank body 101, which is used to close the filled tank body 101 and store the urea solution; specifically, the blocking piece 103 of this scheme can be a piston, which blocks the tank body 101, and when the protective shell 102 slides downward, the blocking piece 103 can be opened.

[0045] The tray 201 is a cylindrical sleeve, and the tray has a sealing design at the bottom; a moving block 203 slides on the outer wall of the tray 201, and the moving block 203 passes through the outer wall of the tray 201, and a first inclined surface 203a is provided on the surface of the moving block 203 close to the outside, and a second inclined surface 203b is provided on the surface close to the inside. When the protective shell 102 moves downward, it pushes the intercepting plate 102a to move downward, and at the same time, the intercepting plate 102a slides along the surface of the first inclined surface 203a, pushing the moving block 203 to move toward the inside of the tray 201. At this time, the lower surface of the tank body 101 will fit the surface of the second inclined surface 203b. Since the outer surface of the moving block 203 is restricted by the intercepting plate 102a, the moving block 203 will lift the tank body 101; then the blocking piece 103 of the tank body 101 is opened and aligned with the discharge port at the bottom of the dissolving tank; four moving wheels 202 are installed on the lower surface of the tray 201. This scheme is to prevent the tank body 1 01 is moved by impact, and the moving wheel 202 adopts a self-fixed universal wheel. This technology is a prior art and will not be repeated here. As the liquid inside the tank body 101 is filled, the tank body 101 is pushed away, and then the protective shell 102 is pushed upward. The tank body 101 slides along the surface of the second inclined surface 203b, and then the tank body 101 pushes the moving block 203 outward, and the first slide groove 203c is exposed to the outside of the tray 201, pushing the protective shell 102 downward, and the intercepting plate 102a at the bottom of the protective shell 102 slides into the inside of the first slide groove 203c. The outer wall of the tank body 101 has an outward force on the moving block 203. In addition, the moving block 203 has no upward thrust, so when the intercepting plate 102a slides into the inside of the first slide groove 203c, the moving block 203 has a limiting effect on the protective shell 102, so that there is a certain space between the tray 201 and the surface of the tank body 101. If a collision occurs, direct contact with the tank body 101 is avoided.

[0046] Example 2

[0047] Reference Figure 1 to Figure 8 , which is the second embodiment of the present invention, and is different from the first embodiment in that: it also includes a fixing platform 101a provided on the outer wall of the tank body 101, and the intercepting plate 102a passes through the fixing platform 101a.

[0048] Among them, there is a circular fixed platform 101a on the outer wall of the tank body 101, and the interception plate 102a passes through the fixed platform 101a. The advantage of designing the fixed platform 101a is that there may be mechanical transportation in the future, which prevents the manipulator (conventional manipulator arm) from directly contacting the surface of the tank body 101, and also prevents the gripper from directly clamping the interception plate 102a, thereby avoiding wear on the tank body 101 or the interception plate 102a.

[0049] A first slide cylinder 101b is disposed on the end surface of the tank body 101, and a second slide cylinder 102b is disposed on the end surface of the protective shell 102; the second slide cylinder 102b slides along the outer wall of the first slide cylinder 101b.

[0050] A cylindrical first slide cylinder 101b is fixedly mounted on the upper surface of the tank body 101, and a similar second slide cylinder 102b is mounted on the upper surface of the protective shell 102, and the inner wall of the second slide cylinder 102b can slide along the outer wall surface of the first slide cylinder 101b.

[0051] This scheme is different from Example 1. The blocking member 103 includes a closing plate 103a arranged in an array inside the first slide cylinder 101b, a first slide bar 103a-1 is fixedly provided on the upper and lower surfaces of the closing plate 103a, a track disk 103b is fixedly installed on the inner wall of the first slide cylinder 101b, a second slide groove 103b-1 for sliding the first slide bar 103a-1 is penetrated through the surface of the track disk 103b, a disc 103c is rotatably installed inside the first slide cylinder 101b, a third slide groove 103c-1 for sliding the first slide bar 103a-1 is provided on the surface of the disc 103c close to the closing plate 103a, the closing plate 103a is between the disc 103c and the track disk 103b, a second slide bar 103c-2 is provided on the outer wall of the disc 103c, and the second slide bar 103c-2 passes through the first slide cylinder 101b.

[0052] The blocking member 103 is installed inside the first slide 101b, wherein a plurality of closing plates 103a are arranged in an array, and each closing plate 103a is attached to each other, and a sealing gasket is attached to the surface of the attached surface. Figure 7 As shown, the closing plate 103a has inclined surfaces on the fitting surfaces. When opened, the closing plates 103a will slide against each other along the inclined surfaces, thereby rotating to open a passage for the solution to enter the interior of the tank body 101; the disc 103c is above the closing plate 103a, and the track disc 103b is below the closing plate 103a. The lower surface of the disc 103c has a hexagonal third slide groove 103c-1, and the first slide bar 103a-1 fixedly installed on the upper surface of the closing plate 103a can slide inside one side of the hexagonal third slide groove 103c-1; the track disc 103b has six second slide grooves 103b-1 running through it, each second slide groove 103b-1 corresponds to one side of the hexagonal third slide groove 103c-1, and the second slide groove 103b-1 is not parallel to the side of the corresponding hexagonal third slide groove 103c-1 (such as Figure 8As shown); the first slide bar 103a-1 on the lower surface of the closing plate 103a slides along the inside of the second slide groove 103b-1, and the upper and lower slide bars of the closing plate 103a are both cylindrical, and the axes are in the same straight line; therefore, when the second slide cylinder 102b moves downward, the fourth slide groove 102b-1 will push the second slide bar 103c-2 to rotate, thereby driving the disc 103c to rotate. Since the track disc 103b is fixed, when the disc 103c rotates, the first slide bar 103a-1 will slide along the third slide groove 103c-1 and the inside of the second slide groove 103b-1 at the same time, so that the closing plates 103a slide against each other, thereby opening the blocking member 103.

[0053] The inner wall of the second slide cylinder 102b is provided with a fourth slide groove 102b-1 for the second slide rod 103c-2 to slide.

[0054] In order to facilitate the operation, a fourth slide groove 102b-1 is provided on the inner surface of the second slide cylinder 102b, and the fourth slide groove 102b-1 is an upward spiral slide groove, and the second slide rod 103c-2 passes through the first slide cylinder 101b and extends to the inside of the fourth slide groove 102b-1; it should be noted that when the protective shell 102 moves downward, in order to drive the second slide rod 103c-2 to slide, thereby driving the disc 103c to rotate, the first slide cylinder 101b is provided with a plurality of slide rods 103c-2, and the plurality of slide rods 103c-2 are ... 1b digs a transverse groove 101b-1 to provide a rotation space for the second slide bar 103c-2; the second slide bar 103c-2 passes through the transverse groove 101b-1, and the second slide bar 103c-2 extends to the inside of the fourth slide groove 102b-1. When the second slide cylinder 102b moves downward, the fourth slide groove 102b-1 will push the second slide bar 103c-2 to rotate along the inside of the transverse groove 101b-1, driving the disc 103c to rotate, thereby realizing the opening of the blocking member 103.

[0055] In summary, when it is necessary to store urea solution, the protective shell 102 is pushed downward, and the protective shell 102 pushes the moving block 203 into the inside of the tray 201. Due to the restriction of the moving block 203 by the interception plate 102a fixed on the lower surface of the protective shell 102, the moving block 203 will lift the tank body 101 by the second inclined surface 203b inside and will not move outward; in the process of the protective shell 102 moving downward to contact the surface of the tank body 101, the fourth slide groove 102b-1 on the inner wall of the second slide cylinder 102b drives the disc 103c to rotate, thereby opening the first slide cylinder 101b, and then the solution is injected; when the tank body 101 is full, the tank body 101 is moved away, the blocking member 103 is treated with residual liquid, and then the protective shell 102 is moved upward, the restriction of the moving block 203 by the protective shell 102 is released, and then the tank body 101 moves downward, driving the protective shell 102 to move downward together, and the interception plate 102a enters the first In the slide groove 203c; the advantage of such a design is that, after the solution is stored, an indirect connection is made between the protective shell 102, the tray 201 and the tank body 101, so that it is more stable when moving; at the same time, when performing the next step of work, directly grab the fixed table 101a, at this time, the tank body 101 and the tray 201 will be directly separated, and at this time, the intercepting plate 102a will not move relative to the tank body 101, so that the tank body 101 and the protective shell 102 can be directly aligned with the injection port of the next process and directly installed. When the protective shell 102 contacts the injection port, it will push the protective shell 102, and the protective shell 102 will reopen the first slide cylinder 101b, so there is no need to redo the connection device between the tank body 101 and the next process; at the same time, the moving component 200 can also be separated from the storage component 100, and the moving component 200 can continue to be used in combination with the next storage component 100.

[0056] Example 3

[0057] Reference Figure 1 to Figure 13 , which is the third embodiment of the present invention, is different from the first two embodiments in that: the end surface array of the tray 201 is provided with a damper 204, and the damper 204 is externally sleeved with a first elastic member 205.

[0058] Among them, a damper 204 is fixedly installed on the inner surface of the bottom of the tray 201. There are four damper 204 arrays, and the outer wall of each damper 204 is sleeved with a first elastic member 205. The first elastic member 205 is a compression spring. The damper 204 is combined with the first elastic member 205 to have a certain buffering effect on the tank body 101. After the liquid is filled, the protective shell 102 is pushed upward, and the downward movement of the tank body 101 will become slow, making the overall device safer and more reliable.

[0059] A support plate 206 is provided at one end of the damper 204 away from the tray 201, a sleeve 206a is provided on the surface of the support plate 206, and a first sliding block 206a-1 is provided on the inner wall of the sleeve 206a;

[0060] A support rod 207 is slidably disposed inside the sleeve 206a, and a reset groove 207a is disposed on the outer wall of the support rod 207 for the first slider 206a - 1 to slide. The other end of the support rod 207 is connected to the moving wheel 202 .

[0061] Among them, a support plate 206 is fixed above the damper 204, and the support plate 206 increases the contact surface with the tank body 101 and increases the force-bearing surface; at the same time, on the lower surface of the support plate 206, an array is provided with four sleeves 206a, and the support rod 207 is slidably connected with the sleeve 206a. At the same time, the first slider 206a-1 can slide along the inside of the reset groove 207a, so as to control the moving wheel 202; it should be noted here that the moving wheel 202 is provided with four, and when installing, the two symmetrical moving wheels 202 are installed in parallel, and the adjacent two are installed vertically, such as Figure 1 As shown, the four wheels are constrained by each other and cannot move.

[0062] The reset groove 207a includes a movable channel 207a-1 on the outer wall of the support rod 207, and a diamond block 207a-2 is arranged in an array on the surface of the movable channel 207a-1.

[0063] A first limiting groove 207a - 3 is formed between the rhombus blocks 207a - 2 .

[0064] A first circular groove 207a-4 and a second circular groove 207a-5 are formed between the rhombus block 207a-2 and the inner wall of the movable channel 207a-1.

[0065] A bearing 208 is provided between the support rod 207 and the tray 201 .

[0066] Among them, the active channel 207a-1 makes the radius of the middle part of the support rod 207 smaller than the radius of the support rod 207, and there is a diamond block 207a-2 on the surface of the active channel 207a-1. Two diamond blocks 207a-2 are symmetrically arranged, and the place where the two corners of the diamond block 207a-2 are close to each other is a vertical surface, and the first limiting groove 207a-3 is formed between the vertical surfaces; the distance between the upper and lower corners of the diamond block 207a-2 and the upper and lower surfaces of the active channel 207a-1 forms a first circular groove 207a-4 and a second circular groove 207a-5.

[0067] It should be noted that in this solution, the moving wheel 202 no longer uses a universal wheel, but a common wheel. A support rod 207 is fixedly installed on the upper surface of the wheel, and a bearing 208 is fixedly installed on the outer wall of the support rod 207. When not in use, the first slider 206a-1 inside the sleeve 206a on the lower surface of the support plate 206 is in the position of the first circular groove 207a-4. At this time, pushing the device does not affect the free rotation of the support rod 207. When it is needed, the protective shell 102 is pushed downward. When the protective shell 102 contacts the surface of the tank body 101, the blocking piece is opened in this process. 103, at the same time, the interception plate 102a on the lower surface of the protective shell 102 slides along the first inclined surface 203a outside the moving block 203, and pushes the moving block 203 inward close to the second inclined surface 203b inside the tray 201. At this time, the moving block 203 is not in contact with the support plate 206; then the protective shell 102 is pushed downward, which will drive the tank body 101 to move downward. In this process, the tank body 101 will drive the support plate 206 to move downward for a distance. During this distance, the first slider 206a-1 inside the sleeve 206a will move from the first circular groove 207a -4 slides along the diamond block 207a-2 into the limiting groove 207a-3, and this process drives the support rod 207 to rotate, and resets the moving wheel 202 to the initial installation state to prevent the whole device from moving; at this time, the first slider 206a-1 moves to the position of the first limiting groove 207a-3 to limit the rotation of the moving wheel 202; the second slide cylinder 102b above the protective shell 102 contacts the surface of the discharge port below the dissolving tank; then the solution is injected, and after it is filled, the whole device is pushed away, and the protective shell 102 is pushed upward, and then the first slide cylinder 101b of the tank body 101 is closed , under the action of the damper 204 and the first elastic member 205, the tank body 101 slowly moves downward, squeezing the first elastic member 205; during this process, the lower surface of the tank body 101 will slide along the surface of the second inclined surface 203b, pushing the moving block 203 outward, and the tank body 101 continues to move downward, while driving the protective shell 102 to move downward, and the intercepting plate 102a enters the first slide groove 203c; at the same time, during this process, the first slider 206a-1 enters the second circular groove 207a-5, and the support rod 207 can rotate freely again; the entire device can move freely.

[0068] When the internal liquid needs to be used, the fixed table 101a can be directly clamped by a robot arm, and then the tank body 101 is clamped up. During the clamping process, the first elastic member 205 releases elastic potential energy, and the intercepting plate 102a begins to slide out from the first slide groove 203c, and the tank body 101 separates from the moving component 200. At the same time, the support plate 206 begins to move upward, and the first slider 206a-1 inside the sleeve 206a enters the first circular groove 207a-4, and the restriction is released again, so that the moving component 200 can move freely. When using it next time, you can first push the moving block 203 inwards, and then the second inclined surface 203b inside the moving block 203 will abut against the lower surface of the support plate 206, which is convenient for the next use; it should be noted here that in order to prevent the moving block 203 from detaching from the tray 201, this solution installs two abutment blocks 203d on the lower surface of the moving block 203, and the two abutment blocks 203d are respectively fixed on the surface of the moving block 203 close to the inside of the tray 201, and the other is fixed on the surface of the moving block 203 close to the outside, and there is enough space between the two for the moving block 203 to move and ensure that the moving block 203 can move smoothly. The moving block 203 will not separate from the tray 201; when the moving block 203 moves inward, the resistance block 203d on the outside of the moving block 203 can contact the outer surface of the tray 201 to prevent the moving block 203 from separating from the tray 201 when the intercepting plate 102a pushes the moving block 203 to move; when the moving block 203 is pushed outward by the tank body 101, the resistance block 203d of the moving block 203 close to the inner surface of the tray 201 can contact the inner surface of the tray 201 to prevent the tank body 101 from pushing the moving block 203 out and the moving block 203 from separating from the tray 201.
