TECHNICAL FIELD

[0001] The present application relates to a kind of tableware cleaning equipment, especially it is related to drum-type tableware cleaning equipment. BACKGROUND

[0002] At present, the existing industrial tableware washing machine technology has the following characteristics: a. In terms of structure, the existing industrial tableware washing machine mainly includes transmission system, spraying system, detergent supply system, control system and other parts. The transmission system is responsible for the transmission of the tableware to be cleaned into the cleaning area; the spraying system sprays the detergent to the surface of the tableware through high-pressure water flow to achieve stain removal; the detergent supply system is responsible for providing detergent to the spraying system; the control system is used to control the operation of the entire equipment. b. In terms of washing technology, the industrial tableware washing machine mainly uses spraying, ultrasonic, vortex and other technologies for cleaning. The spraying cleaning sprays the detergent to the surface of the tableware through high-pressure water flow to remove stains on the tableware; the ultrasonic cleaning uses high-frequency vibration to generate cavitation effect to make the stains fall off the surface of the tableware; the vortex cleaning forms a vortex through high-speed water flow to generate centrifugal force on the tableware to achieve cleaning effect. c. In terms of energy utilization, the existing industrial dishwasher mainly uses electricity, gas, water and other resources. Some high-efficiency energy-saving tableware washing machines use heat recovery systems to improve energy utilization. The existing industrial tableware washing machine has the problems of long flow line and high energy consumption, which need to be improved urgently. SUMMARY

[0009] In the figure: 1 bottom water tank, 2 roller, 3 machine foot seat, 4 drain pipe, 5 motor, 6 motor frame, 7 bearing seat, 8 operation panel, 9 machine door, 10 steam pipe, 11 water supply pipe, 12 spray water supply pipe, 13 roller shaft, 14 auxiliary support, 15 utensil frame lock pin, 16 utensil frame, 17 utensil frame, 18 bowl, 19 plate, 20 utensil frame door, 21 utensil frame main support, 22 door handle lock, 23 machine shell, 24 door shaft, 25 guide plate, 26 utensil frame opening, 27 utensil frame cover, 28 transmission belt, 29 belt pulley, 30 stirring protrusion. DETAILED DESCRIPTION

[0010] From Figure 1 It can be seen that the lower part of the machine is the bottom water tank 1, which is welded with the machine foot seat 3. The upper part of the bottom water tank is the machine shell 23 of the roller 2 part, and the roller is connected with the machine shell bearing through the roller shaft 13 and the bearing seat 7. The motor 5 is fixed on the motor frame 6, which drives the roller to rotate through the transmission belt 28 and the belt pulley 29; the predetermined program of the operation panel 8 controls the forward rotation, reverse rotation, stop and working time of the motor. The electromagnetic valve is installed on the steam pipe 10 and connected with the steam boiler; the electromagnetic valve is installed on the water supply pipe 11 and connected with the tap water pipe; the electromagnetic valve is installed on the spray water supply pipe 12 and connected with the spray pump and water tank; all the electromagnetic valves, motors, spray pumps and steam boilers are controlled by the predetermined program of the control panel. The middle part of the machine shell is provided with a machine door 9, the iron frame of the door is surrounded by sealing rubber strips, and high-strength glass steel glass is inlaid in the middle, which is convenient for observing the working condition of the roller. The utensil in the utensil frame 17 in the roller can be loaded or taken out by opening the machine door, and the cleaning liquid can also be added here. The utensil frame in the roller is composed of the utensil frame main support 21 and the auxiliary support 14 fixed on the roller shaft. In addition, the machine door 9 can be opened on the side, and the utensil frame door 20 can also be opened on the side, so that the pressure of the centrifugal force on the utensil frame lock pin 15 during rotation can be reduced.

[0011] From Figure 2 It can be seen that the cross section of the utensil frame 17 has two types of rectangular and trapezoidal, which can also be designed according to the shape and size of the utensil. In order to facilitate the loading and taking of utensils, utensil frames 16 are arranged in the utensil frame, and when the utensil frames are loaded, the utensil frame lock pin 15 will lock the frame opening to prevent the utensil frames and utensils from being thrown out during the rotation of the roller. The spray pipe 12 is installed on the upper part of the machine shell 23 of the roller, and when the roller turns out of the water surface (generally, the cleaning water depth is half of the roller), the spray holes on the spray pipe will spray the utensils, realizing the integration of washing and spraying.

[0012] FromFigure 3 It can be seen that the utensil frame 16 is provided with uniform partitions, and the utensils are arranged uniformly and separated, which facilitates the washing of the water flow when the drum rotates. The establishment of the utensil frame greatly improves the work efficiency and cleaning effect of utensil loading and unloading.

[0013] By Figure 4 As another embodiment, the utensil frame 16 is cancelled, and the drum is divided into a plurality of cylindrical utensil bins 17. The utensil bin is provided with an agitating protrusion 30. When the drum rotates, the utensils will slide in the utensil bin, and the agitating protrusion 30 will disturb the movement track of the utensils, thereby playing a role of agitating and overturning the utensils. The utensils are scattered and loaded into the utensil bin by opening the utensil bin door 20, and the utensil bin door is locked by the bin door locking pin 15. After the machine door is closed, the cleaning operation can be started. This example requires full water cleaning, which saves the utensil frame loading time, but the cleaning effect is unstable.

[0014] The working principle of the present application: the entire cleaning process can be divided into four stages. The first stage is residue removal and washing, which requires adding cleaning agent, and the focus is to remove oil stains and attachments on the surface of the utensils, which is also the key to the entire cleaning quality. The residue removal and washing should account for three-sixths of the entire cleaning time. The cleaning method adopts alternating changes of drum reverse rotation and forward rotation, and the spray is opened before drainage (the diameter of the drainage pipe should be larger to ensure that the drainage is short and not easily blocked); the second stage of cleaning is the same as the first stage, except that the water supply pipe 11 is opened when the drainage valve is closed, and the water level reaches half of the drum diameter, and then the water supply is stopped, and the total time of six-sixths of the washing and spraying is drained; the third stage of cleaning is the same as the second stage of cleaning, except that the drainage is advanced by a period of time, and a period of time is reserved for the spraying to work alone, to ensure that the utensils are clean and free of residues. The spraying in this stage is better if pure water is used; the fourth stage is drying, and the spray is closed and the steam pipe 10 is opened. At this time, the steam from the steam boiler flows into the drum, and the temperature of the machine body rapidly rises to above 100 degrees. The utensils are subjected to pasteurization while being dried. The effects of washing, drying and disinfection are achieved in one.

[0015] The present application can program the above cleaning process into a predetermined program to realize automatic cleaning, and can be widely used in restaurants and canteens.
