Description

Technical Field

[0001] The utility model relates to the technical field of urea production equipment, in particular to a urea dissolving tank. Background Art

[0002] Urea, also known as carbamide, is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is a white crystal and one of the simplest organic compounds. It is also the main nitrogen-containing end product of protein metabolism and decomposition in mammals and some fish. Urea requires the use of a special dissolving tank during its production process.

[0003] A Chinese utility model patent with the announcement number CN220238256U discloses a dissolving tank for urea ammonia production. The device uses a rotating plate and a feeler rod in combination, so that when the long rod rotates, the feeler rod rotates. When the feeler rod rotates to contact and squeeze the rotating plate, the rotating plate is separated from the discharge pipe. At this time, the particles flow out through the discharge pipe. When the feeler rod rotates to separate from the rotating plate, the torsion spring rebounds and resets, so that the rotating plate is again attached to the discharge pipe, thereby preventing the discharge pipe from continuously discharging. After the intermittent rotation of the rotating plate, the discharge pipe cyclically intermittently discharges quantitatively, so that the dissolution efficiency of urea particles and ionized water is higher, and the use effect of the dissolving tank is improved. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0004] Although the device can realize intermittent material discharge in actual use, due to the fixed material discharge position, when the material is not mixed and stirred in time, it is easy for the material to pile up, thereby affecting the uniformity of material mixing. For this reason, we provide a urea dissolution tank. Utility Model Content

[0005] In order to solve the problem in the above background technology that the material discharge position is fixed, so that when the materials cannot be mixed and stirred in time, the materials are easily piled up, the utility model provides a urea dissolving tank.

[0006] The utility model is implemented by the following technical scheme: a urea dissolving tank, comprising:

[0007] A dissolving tank body, wherein a feeding hopper is arranged above the dissolving tank body, an agitator is rotatably connected inside the dissolving tank body, a motor 1 is fixedly connected to the bottom center of the dissolving tank body, and the rotor end of the motor 1 is coaxially fixedly connected to the agitator;

[0008] A mobile material discharge component, which includes a sliding rod symmetrically fixedly connected to the top of the dissolving tank body through a bracket, a sliding block being slidably connected to the outside of the sliding rod and fixedly connected to the feeding hopper, a two-way screw rod being rotatably connected to the bracket, one end of the two-way screw rod being coaxially fixedly connected to motor 2, moving blocks being threadedly connected to the outside of both sides of the two-way screw rod, a connecting rod being hinged between the moving block and the feeding hopper through a hinge, a material baffle plate being fixedly connected to the bracket and the upper surface of the material baffle plate is in contact with the bottom of the feeding hopper, and material discharge slots are equidistantly provided on one side of the material baffle plate.

[0009] As a further improvement of the above scheme, the inside of the feeding hopper is rotatably connected to a hollow shaft and one end of the hollow shaft extends to the outside of the feeding hopper, the outside of the hollow shaft is equidistantly and circumferentially fixedly connected with a stirring rod, the bracket is fixedly connected to a cross bar and one end of the cross bar extends to the inside of the hollow shaft, a connecting piece is provided inside the hollow shaft and the connecting piece and the cross bar are fixedly connected, balls are symmetrically and movably connected to the connecting piece, and spiral grooves are symmetrically provided on the inner wall of the hollow shaft.

[0010] As a further improvement of the above solution, a guide rod is fixedly connected below the bidirectional screw rod and the guide rod is slidably connected to the moving block.

[0011] As a further improvement of the above solution, the width of the material baffle plate is greater than the width of the discharge port of the feeding hopper.

[0012] As a further improvement of the above solution, the width of the discharge slot is consistent with the width of the discharge port of the charging hopper.

[0013] As a further improvement of the above solution, the balls are matched with the spiral grooves.

[0014] As a further improvement of the above solution, a discharge pipe is fixedly connected to a lower portion of one side of the dissolving tank body.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model drives the bidirectional screw rod to rotate alternately in positive and negative directions regularly through the second motor, so that the two groups of moving blocks connected with the screw rod can be driven to move alternately toward or away from each other, and the moving block and the hinged effect between the feeding hopper and the connecting rod, and the sliding cooperation between the slider and the slide rod can make the feeding hopper be pushed and pulled to move back and forth horizontally. When the moving feeding hopper passes through the equally spaced feeding notches, the urea particles will automatically fall into the dissolving tank body through the feeding notches, which not only increases the feeding range of the urea particles, but also can control the feeding amount. It is highly practical and effectively avoids the problem of material accumulation when the materials are not mixed and stirred in time due to the fixed feeding position, thereby ensuring the uniformity of the urea solution.

[0017] 2. The utility model also drives the hollow shaft to move during the movement of the hopper. The cooperation between the ball and the spiral groove and the rotation cooperation between the hollow shaft and the hopper can drive the hollow shaft to rotate. The rotation of the hollow shaft drives the stirring rod to rotate, so that the urea particles inside the hopper can be stirred to prevent clogging, thereby ensuring the stability and continuity of the urea solution during preparation and further improving the practicability of the device.

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Embodiment 1:

[0026] Please combine Figure 1-4 , a urea dissolving tank of this embodiment includes:

[0027] A dissolving tank body 1, a hopper 2 is arranged above the dissolving tank body 1, an agitator 3 is rotatably connected inside the dissolving tank body 1, a motor 1 is fixedly connected to the bottom center of the dissolving tank body 1, and the rotor end of the motor 1 is coaxially fixedly connected to the agitator 3, and a discharge pipe is fixedly connected to the lower part of one side of the dissolving tank body 1 to facilitate the discharge of urea solution;

[0028] The mobile material discharge component includes a slide bar 101 symmetrically fixedly connected to the top of the dissolving tank body 1 through a bracket, a slider 102 is slidably connected to the outside of the slide bar 101 and the slider 102 is fixedly connected to the feeding hopper 2, a bidirectional screw rod 103 is rotatably connected to the bracket, one end of the bidirectional screw rod 103 is coaxially fixedly connected to the motor 2, both sides of the bidirectional screw rod 103 are threadedly connected to the outside of the moving block 104, the moving block 104 and the feeding hopper 2 are hinged with a connecting rod 105 through a hinge, a baffle plate 106 is fixedly connected to the bracket and the upper surface of the baffle plate 106 contacts the bottom of the feeding hopper 2, and a material discharge slot 107 is equidistantly provided on one side of the baffle plate 106, the width of the baffle plate 106 is greater than the width of the material discharge port of the feeding hopper 2, and the width of the material discharge slot 107 is consistent with the width of the material discharge port of the feeding hopper 2.

[0029] The inside of the feeding hopper 2 is rotatably connected to a hollow shaft 201 and one end of the hollow shaft 201 extends to the outside of the feeding hopper 2, the outside of the hollow shaft 201 is equidistantly and circumferentially fixedly connected to a stirring rod 202, a cross bar 203 is fixedly connected to the bracket and one end of the cross bar 203 extends to the inside of the hollow shaft 201, a connecting piece is provided inside the hollow shaft 201 and the connecting piece and the cross bar 203 are fixedly connected, balls 204 are symmetrically and movably connected to the connecting piece, and spiral grooves 205 are symmetrically provided on the inner wall of the hollow shaft 201, and the balls 204 and the spiral grooves 205 are adapted to each other.

[0030] The implementation principle of a urea dissolving tank in the embodiment of the present application is as follows: first, urea granules are added to the inside of the feeding hopper 2 at one time. Since the feeding hopper 2 is on the top left side of the baffle plate 106, the baffle plate 106 can block the discharge port of the feeding hopper 2 at this time, and then start motor 1 and motor 2. Motor 1 drives the agitator 3 to rotate, so that the solution inside the dissolving tank body 1 can be fully stirred. Motor 2 can drive the bidirectional screw rod 103 to rotate regularly and alternately, thereby driving the two groups of moving blocks 104 threadedly connected thereto to move alternately toward or away from each other. By utilizing the hinged action between the moving block 104 and the feeding hopper 2 and the connecting rod 105, the sliding cooperation between the slider 102 and the slide rod 101 makes it possible to push and pull the feeding hopper 2 to move back and forth horizontally. When the moving feeding hopper 2 passes through the discharge slots 107 set at equal distances, the urea granules will automatically pass through The feeding notch 107 falls into the dissolving tank body 1, which not only increases the feeding range of urea granules, but also can control the feeding amount, thereby avoiding the problem of material accumulation when the material cannot be mixed and stirred in time due to the fixed feeding position, and ensuring the uniformity of urea solution mixing. At the same time, during the movement of the feeding hopper 2, the hollow shaft 201 will also be driven to move together, and the cooperation between the ball 204 and the spiral groove 205 and the rotation cooperation between the hollow shaft 201 and the feeding hopper 2 can be used to drive the hollow shaft 201 to rotate, and the rotation of the hollow shaft 201 drives the stirring rod 202 to rotate, so that the urea granules inside the feeding hopper 2 can be stirred to prevent it from being blocked, thereby ensuring the stability and continuity of the urea solution during preparation, and finally opening the discharge pipe to discharge the prepared urea solution out of the dissolving tank body 1.

[0031] Embodiment 2:

[0032] The present embodiment is further improved on the basis of the embodiment 1 in that a guide rod is fixedly connected below the bidirectional screw rod 103 and the guide rod is slidably connected to the moving block 104 , which can play a certain guiding role in the horizontal movement of the moving block 104 .
