A rotor is fixed to the bottom of the connecting main shaft, and a stator is fixed on the inner wall of the internal cylinder 154. The two cooperate with each other, wherein a discharge pipe is connected to the lower side wall of the main cylinder 11, and a bent portion is formed inside the discharge pipe. The bottom end of the bent portion is fixed on the first flange end plate 151 (which can be fixed by welding or other methods) and communicates with the discharge through hole formed on the first flange end plate 151. The above structure is basically the same as the existing emulsifier and will not be described in detail.

[0021] In this embodiment, the main cylinder 11 and the following components are inserted into the frame 20, the bottom of the frame 20 is fixed to the mounting seat below, and a plurality of edge support frames 30 are fixed to the bottom surface of the edge of the flange connection plate 12 at the top of the main cylinder 11, and the bottom surface of the edge support frame 30 is fixed to the top of the frame 20;

[0022] An extension portion 14 is formed on the edge of the middle flange edge 13 at the upper part of the middle part of the main cylinder body 11, and a four-parameter combination probe 50 is fixed to the top surface of the extension portion 14.

[0023] The lower cylinder 15 includes a first flange end plate 151, a second flange end plate 152, a middle cylinder 153 and an inner cylinder 154.

The bottom ends of the middle cylinder 153 and the inner cylinder 154 are welded and fixed to the top end surface of the second flange end plate 152 at the same time. A discharge through hole is formed on the first flange end plate 151, which is communicated with the inner cylinder 154. A feed through hole 155 is formed in the middle of the bottom surface of the second flange end plate 152, which is communicated with the inner cylinder 154. A cooling cavity 1 is formed between the middle cylinder 153 and the inner cylinder 154. The upper part of one side of the middle cylinder 153 is connected to a cooling water outlet 2, and the lower part of the other side of the middle cylinder 153 is connected to a cooling water inlet 3.

[0025] By adopting this structure, cooling water enters from the cooling water inlet 3 (the cooling water inlet 3 is connected to the water inlet pipe), flows along the spiral flow channel, and then flows out from the cooling water outlet 2 (the cooling water outlet 2 is connected to the water outlet pipe, the water inlet pipe and the water outlet pipe are connected to the entire water circulation system, the other end of the water inlet pipe is connected to the water outlet end of the water pump in the water tank, the water inlet end of the water pump is connected to the water tank through a connecting pipe, the water outlet end of the water outlet pipe extends into the water tank, and the refluxed water returns to the water tank. The water pump runs, so that the water in the water tank enters the cooling chamber 1 through the water inlet pipe for heat exchange). When flowing in the spiral flow channel, the water exchanges heat with the material in the internal cylinder 154, thereby reducing the temperature inside the internal cylinder 154 and ensuring the normal operation of the equipment. The spiral flow channel increases the flow time of the water in the cooling chamber 1, improves the heat exchange efficiency, makes the heat exchange sufficient, and has a good use effect.

[0026] Furthermore, a lower end cover 60 is fixed to the bottom surface of the second flange end plate 152, and an upper recessed hole 61 is formed in the middle of the top surface of the lower end cover 60, and the upper recessed hole 61 corresponds to and communicates with the feed through hole 155 in upper and lower directions, and a horizontally extending radial extension hole 62 is formed on the side wall of the lower end cover 60, and the inner end of the radial extension hole 62 is communicated with the upper recessed hole 61, and a feed connector 4 is welded and fixed to the outer wall of the lower end cover 60, and the feed connector 4 is communicated with the radial extension hole 62.

The principle is the same as that of the existing emulsifier.

[0029] Furthermore, the edge support frame 30 includes two vertical reinforcing plates 31 and a fixed bottom plate 32, the bottom surfaces of the two vertical reinforcing plates 31 are welded and fixed to the top surface of the fixed bottom plate 32, the side walls of the two vertical reinforcing plates 31 are welded and fixed to the top inner wall of the main cylinder 11, and the top surface of the vertical reinforcing plates 31 is welded and fixed to the bottom surface of the edge of the flange connection plate 12;

[0030] The fixed bottom plate 32 is welded and fixed to the top surface of the top crossbeam of the frame 20 .

[0031] The bottom surfaces of the left, right, front and rear middle parts of the edges of the flange connecting plate 12 at the top of the main cylinder body 11 are welded and fixed with edge support frames 30, and all edge support frames 30 are evenly distributed on the bottom surface of the edge of the flange connecting plate 12 with the central axis of the flange connecting plate 12 as the center.

[0032] The side support frame 30 enables the main cylinder 11 and the frame 10 to be firmly fixed, that is, the emulsifier body 10 and the frame 10 are fixed through the side support frame 30, and the fixation is firm.

[0033] During operation, the four-parameter combination probe 50 is used to constantly detect the displacement caused by the vibration of the entire emulsifier host 10, and the sensing signal is transmitted to the control host through the signal line of the four-parameter combination probe 50 (the four-parameter combination probe 50 is electrically connected to the control host through a signal transmission cable). The control host detects the transmitted signal. When it meets the set value range, no alarm is issued. When its signal data exceeds the set value range, the corresponding alarm is controlled to sound a warning to remind the operator to shut down the equipment and perform maintenance.

[0034] The four-parameter combination probe 50 in this embodiment is a KR-939SB4 integrated four-parameter combination probe, which is a non-bus structured general-purpose combination transmitter in the KR-939 series cooling tower fan safety monitoring system of Beijing Kere Company. The probe can monitor the most critical safety operation indicator of the controlled equipment-mechanical vibration in all directions. It simultaneously completes high-quality vibration measurements in three orthogonal directions of X, Y, and Z, in accordance with the ISO-2372 standard of the International Organization for Standardization. The probe uses a micro-machining process vibration sensor originating from the United States. The vibration signal obtained by the sensor is then passed through a bandpass filter, a converter, an amplifier, and a true effective value converter, and finally a 4-20mA standard current signal proportional to the vibration intensity is generated by the voltage / current drive circuit. Four two-wire 4-20mA transmitters are integrated in the probe, which can be directly connected to a computer data acquisition and control system (DCS, PLC, etc.).

[0035] Therefore, in this embodiment, only one four-parameter combined probe 50 is required to detect the vibrations of the emulsifier host 10 in three orthogonal directions of X, Y, and Z. The detection is comprehensive, accurate, effective, and easy to install.

Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
