Technical Field
[0001] This utility model relates to the field of mixer technology, and in particular to a refractory brick mortar mixer. Background Technology
[0002] The mixer is used to mix refractory brick mortar during refractory brick production. The mixer consists of a mixing tank on a fixed support, a motor, an agitator, and a discharge plate. When using the mixer to mix the refractory brick mortar, the refractory brick mortar and water are poured into the mixing tank on the support. The motor is started, and the motor is connected to the agitator through a reducer and a coupling, causing the agitator to rotate and thus mix the refractory brick mortar. After mixing is completed, the discharge plate is pulled out to discharge the mortar.
[0003] The inventors discovered in their daily work that when using a mixer, because refractory brick mortar often contains large particles, and some existing mixers do not have a mechanism to crush these large particles, these large particles directly participate in the mixing process, which may lead to uneven mixing and excessive porosity. Utility Model Content
[0004] The purpose of this invention is to solve the problem that, in practical use, refractory brick mortar often contains large particles, and some existing mixers do not have a mechanism to crush these large particles. This results in large particles directly participating in the mixing process, which may lead to uneven mixing and excessive porosity. Therefore, this invention proposes a refractory brick mortar mixer.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a refractory brick mortar mixer, comprising a mixing tank fixedly connected to a support, a feeding plate inserted into the arc surface of the mixing tank, an agitator provided on the inner wall of the mixing tank, a motor installed at the lower end of the mixing tank, the motor controlling the rotation of the agitator, a crushing assembly provided at the upper end of the mixing tank, the crushing assembly comprising a crushing hopper provided at the upper end of the mixing tank, a first filter screen fixedly connected to the inner wall of the crushing hopper, and a detachably connected rotating shaft provided at the upper end of the agitator, the arc surface of the rotating shaft being fixedly connected to a rotating crushing blade.
[0006] The effect achieved by the above components is as follows: by setting up the crushing component, when it is necessary to crush the refractory brick mortar, the refractory brick mortar is poured into the crushing hopper, the motor is started by the controller, the motor drives the agitator to rotate, the shaft rotates, and the rotating crushing blades rotate, thereby crushing the refractory brick mortar. The crushed refractory brick mortar falls into the mixing tank through the mesh of the first filter screen, thus achieving the effect of crushing the refractory brick mortar as much as possible.
[0007] Preferably, a fixed crushing blade is fixedly connected to the inner wall of the crushing bucket, and the fixed crushing blade and the rotating crushing blade are distributed alternately.
[0008] The effect achieved by the above components is to assist in crushing refractory brick mortar by setting a fixed crushing blade in conjunction with a rotating crushing blade.
[0009] Preferably, the inner wall of the crushing bucket is fixedly connected with a second filter screen and a third filter screen, and the rotating shaft passes through the first filter screen, the second filter screen and the third filter screen, and the diameter of the filter holes of the first filter screen, the second filter screen and the third filter screen increases sequentially.
[0010] The effect achieved by the above components is as follows: by setting up a second filter screen and a third filter screen, the refractory brick mortar poured into the crushing hopper is first filtered by the third filter screen. The refractory brick mortar with a mesh size smaller than the third filter screen falls into the second filter screen, while the refractory brick mortar with a mesh size larger than the third filter screen is crushed by the crushing blade assembly and falls into the second filter screen. Similarly, the refractory brick mortar filtered by the second filter screen falls into the third filter screen, thereby achieving graded crushing and improving crushing efficiency.
[0011] Preferably, a rotating rod is fixedly connected to the arc surface of the rotating shaft, an installation rod is slidably connected to the inner wall of the rotating rod, and a flexible poking rod is fixedly connected to the upper end of the installation rod.
[0012] The effect achieved by the above components is as follows: by setting the push rod, the rotating shaft rotates, causing the rotating rod to rotate, which in turn causes the push rod on the mounting rod to rotate, and the push rod pushes into the mesh of the filter screen, thereby preventing the filter screen assembly from clogging.
[0013] Preferably, a first spring is fixedly connected to the lower end of the mounting rod, and the other end of the first spring is fixed to the rotating rod.
[0014] The effect achieved by the above components is as follows: by setting the first spring, the stick contacts the filter screen, the first spring is compressed, and its reverse force pushes the mounting rod, so that the stick contacts the filter screen fully.
[0015] Preferably, a connecting rod is fixedly connected to the lower end of the crushing bucket, the connecting rod is inserted into the mixing tank, and an insert rod is inserted into the arc surface of the mixing tank, the insert rod being inserted into the connecting rod.
[0016] The effect achieved by the above components is to: drag the insert rod to separate it from the connecting rod, disconnect the shaft from the agitator, and thus disassemble the mixing tank.
[0017] Preferably, one end of the insertion rod is fixedly connected to a second spring, and the other end of the second spring is fixed to the mixing tank.
[0018] The effect achieved by the above components is that by setting a second spring, the second spring pulls the insertion rod, thereby limiting the insertion rod.
[0019] Preferably, the arc surface of the insert rod is provided with a protrusion, and the stirrer and the rotating shaft are threaded together.
[0020] The effect achieved by the above components is that the thread direction of the stirrer and the shaft is consistent with the rotation direction of the stirrer. When the connection between the stirrer and the shaft is released, the stirrer remains stationary while the shaft is rotated in the opposite direction, thereby releasing the fixation.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] In this invention, by setting up a crushing component, when it is necessary to crush the refractory brick mortar, the refractory brick mortar is poured into the crushing hopper, and the motor is started by the controller. The motor drives the agitator to rotate, causing the rotating shaft to rotate, which in turn causes the rotating crushing blades to rotate, thereby crushing the refractory brick mortar. The crushed refractory brick mortar then falls through the mesh of the first filter screen into the mixing tank, thus achieving the effect of crushing the refractory brick mortar as much as possible. This solves the problem that refractory brick mortar often contains large particles, and some existing mixers do not have a mechanism for crushing large particles. This results in large particles directly participating in the mixing of raw materials, which may lead to uneven mixing and excessive porosity. Attached Figure Description

[0028] Reference Figure 1 and Figure 2As shown, this utility model provides a technical solution: a refractory brick mud mixer includes a mixing tank 1 fixedly connected to a support 6, a feeding plate 3 inserted into the arc surface of the mixing tank 1, an agitator 4 provided on the inner wall of the mixing tank 1, a motor 5 installed at the lower end of the mixing tank 1, the motor 5 controlling the rotation of the agitator 4, and a crushing component 2 provided at the upper end of the mixing tank 1.
[0029] Reference Figure 2 and Figure 3 As shown in this embodiment: the crushing component 2 includes a crushing hopper 21 disposed at the upper end of the mixing tank 1. A first filter screen 22 is fixedly connected to the inner wall of the crushing hopper 21. A detachably connected rotating shaft 23 is disposed at the upper end of the agitator 4. A rotating crushing blade 24 is fixedly connected to the arc surface of the rotating shaft 23. By setting the crushing component 2, when it is necessary to crush the refractory brick mortar, the refractory brick mortar is poured into the crushing hopper 21. The motor 5 is started by the controller. The motor 5 drives the agitator 4 to rotate, causing the rotating shaft 23 to rotate, and causing the rotating crushing blade 24 to rotate. The rotating shaft 23 passes through the mesh of the first filter screen 22 and falls into the mixing tank 1, thereby maximizing the crushing effect on the refractory brick mortar. Fixed crushing blades 25 are fixedly connected to the inner wall of the crushing hopper 21. The fixed crushing blades 25 and rotating crushing blades 24 are staggered, and the fixed crushing blades 25 work in conjunction with the rotating crushing blades 24 to assist in crushing the refractory brick mortar. A second filter screen 27 and a third filter screen 26 are fixedly connected to the inner wall of the crushing hopper 21. The filter screens 22, 27, and 26 have progressively larger pore diameters. By using the second and third filters 27 and 26, the refractory brick mortar poured into the crushing hopper 21 is first filtered by the third filter 26. Refractory brick mortar with pores smaller than the third filter 26 falls into the second filter 27, while refractory brick mortar with pores larger than the third filter 26 is crushed by the crushing blades and falls into the second filter 27. Similarly, the second filter 27... The filtered refractory brick slurry falls into the third filter screen 26, thereby achieving graded crushing and improving crushing efficiency. A rotating rod 211 is fixedly connected to the arc surface of the rotating shaft 23. An installation rod 213 is slidably connected to the inner wall of the rotating rod 211. A flexible poking rod 214 is fixedly connected to the upper end of the installation rod 213. By setting the poking rod 214, the rotating shaft 23 rotates, causing the rotating rod 211 to rotate, which in turn causes the poking rod 214 on the installation rod 213 to rotate. The poking rod 214 then pokes into the mesh of the filter screen, thereby preventing the filter screen assembly from clogging.
[0030] Reference Figure 2 and Figure 4As shown in this embodiment: a first spring 212 is fixedly connected to the lower end of the mounting rod 213, and the other end of the first spring 212 is fixed to the rotating rod 211. By setting the first spring 212, the push rod 214 contacts the filter screen, and the first spring 212 is compressed, causing its reverse force to push the mounting rod 213, so that the push rod 214 makes full contact with the filter screen. A connecting rod 28 is fixedly connected to the lower end of the crushing bucket 21. The connecting rod 28 is inserted into the mixing tank 1, and a push rod 29 is inserted into the arc surface of the mixing tank 1. The push rod 29 is inserted into the connecting rod 28. Dragging the push rod 29 separates it from the connecting rod 28. The connection between the rotating shaft 23 and the stirrer 4 is released, thereby disassembling the mixing tank 1. One end of the insertion rod 29 is fixedly connected to a second spring 210, and the other end of the second spring 210 is fixed to the mixing tank 1. By setting the second spring 210, the second spring 210 pulls the insertion rod 29, thereby limiting the insertion rod 29. The arc surface of the insertion rod 29 is provided with a protrusion. The stirrer 4 and the rotating shaft 23 are threadedly connected, and the thread direction of the stirrer 4 and the rotating shaft 23 is consistent with the rotation direction of the stirrer 4. When releasing the connection between the stirrer 4 and the rotating shaft 23, keep the stirrer 4 stationary and rotate the rotating shaft 23 in the opposite direction to release the fixation.
[0031] Working principle:
[0032] When using a mixer to mix refractory brick mortar, the refractory brick mortar and water are poured into the mixing tank 1 on the support 6. The motor 5 is started, and the motor 5 is connected to the mixer 4 through a reducer and coupling, causing the mixer 4 to rotate, thereby mixing the refractory brick mortar. After mixing, the discharge plate 3 is pulled out to discharge the mortar. When it is necessary to crush the refractory brick mortar, the refractory brick mortar is poured into the crushing hopper 21. The motor 5 is started through the controller, and the motor 5 drives the mixer 4 to rotate, causing the rotating shaft 23 to rotate, which in turn causes the rotating crushing blade 24 to rotate. The refractory brick mortar is crushed by the movement of the filter screen 22. The crushed refractory brick mortar then falls into the mixing tank 1 through the mesh of the first filter screen 22, thus maximizing the crushing effect on the refractory brick mortar. The crushing is further assisted by the fixed crushing blade 25 and the rotating crushing blade 24. The refractory brick mortar is poured into the crushing hopper 21 through the second filter screen 27 and the third filter screen 26. It is first filtered by the third filter screen 26. The refractory brick mortar with meshes smaller than the third filter screen 26 falls into the second filter screen 27, while the refractory brick mortar with meshes larger than the third filter screen 26 falls into the second filter screen 27. The refractory brick mortar is crushed by the crushing blade assembly and falls into the second filter screen 27. Similarly, the refractory brick mortar filtered by the second filter screen 27 falls into the third filter screen 26, thus achieving graded crushing and improving crushing efficiency. By setting the push rod 214, the rotating shaft 23 rotates, causing the rotating rod 211 to rotate, which in turn causes the push rod 214 on the mounting rod 213 to rotate. The push rod 214 pushes into the mesh of the filter screen, thus preventing the filter screen assembly from clogging. By setting the first spring 212, when the push rod 214 contacts the filter screen, the first spring 212 is compressed. The reverse force pushes the mounting rod 213, causing the push rod 214 to fully contact the filter screen. The push rod 29 is dragged, separating it from the connecting rod 28, thus disconnecting the shaft 23 from the agitator 4 and disassembling the mixing tank 1. A second spring 210 is provided, which pulls the push rod 29 to limit its position. The thread direction of the agitator 4 and the shaft 23 is consistent with the rotation direction of the agitator 4. When disconnecting the agitator 4 from the shaft 23, the agitator 4 is kept stationary while the shaft 23 is rotated in the opposite direction to release the fixation.
