The technical scheme adopted by the utility model is as follows: an automatic dredging type sludge forming device comprises a material box, a sludge pump, a motor and a speed reducer, wherein two rows of sludge discharge pipes are uniformly arranged on the bottom surface of the material box at intervals, two groups of or four guide rods which are vertically arranged are arranged on the top surface of the material box in a sliding fit mode through guide sleeves, a reset spring is sleeved on the upper portion of each guide rod, the lower ends of the guide rods in the material box are respectively connected with an ejector rod, ejector pins are uniformly arranged below the bottom surface of each ejector rod at intervals, and the ejector pins are matched with the sludge discharge pipes to work; the top surface of the material box is also horizontally provided with two transmission shafts side by side through a bracket, one transmission shaft is driven by the motor and the speed reducer to rotate, each transmission shaft is respectively provided with two cams, the rims of the cams are contacted with the top end of the guide rod, the other ends of the two transmission shafts are respectively provided with gears which are meshed with each other, and the rotation directions of the two transmission shafts are opposite; the top surface of the material box is connected with a sludge pump through a sludge pipe, and a feed inlet of the sludge pump is connected with a hopper.
When the sludge forming machine is used, sludge with the water content of about 78-83% is conveyed to a material box from a pipeline through a sludge pump, and after the sludge enters the material box, the sludge pump continuously gives conveying pressure to discharge the sludge in the material box from the bottom through a sludge outlet hole so as to achieve the purpose of sludge forming. The sludge pump is controlled by frequency conversion to convey, the pressure in the box body is regulated and controlled by controlling the feeding speed, the sludge forming speed is regulated and controlled, the working requirement of the sludge drying equipment is met to the maximum extent, and therefore the sludge drying system can work at the maximum efficiency. The sludge characteristic is between that of liquid and solid, the sludge has strong viscosity and contains impurities such as hair and the like, and the impurities such as hair and the like easily cause blockage of sludge outlet holes; and secondly, the long-time stop can cause the solidification of residual sludge in the equipment and also cause blockage. The two conditions are the main reasons for the blockage of the mud outlet hole and are also an unavoidable working state. This clogging situation is addressed by: 1. the device is characterized in that the mud outlet is subjected to intermittent dredging by the ejector pins under the normal working condition, the number of rows of mud outlets is designed according to the actual mud outlet amount, each row of holes is provided with the corresponding ejector pins, and the ejector pins realize periodic reciprocating motion through the cam structure, so that the ejector pins realize through hole operation. The rotating speed of the cam is controlled by adjusting the frequency of the motor, so that the frequency of the through hole is adjusted. 2. If the motor is started again after being stopped for a long time or hard objects which can not be dredged by other thimbles are met, the cam mechanism is locked, the motor is overloaded, the frequency converter alarms and stops, and the motor is started again after the motor is stopped and foreign matters are manually cleaned through the access hole. Compared with the prior art, the utility model has the advantages that: 1. the sludge enters the sludge drying system in a round strip shape, and the contact area of the sludge is larger than that of the sludge formed by the strip cutting machine, and the shape duration is long; 2. the adjustable range of the sludge forming speed is large, and the output efficiency is high; 3. the structure is simple and the disassembly and the assembly are convenient; 4. the equipment cost is low.
Drawings
The present invention will be described in further detail below with reference to the accompanying drawings.

Detailed Description
An automatic dredging type sludge forming device is shown in figures 1 and 2 and comprises a feed box 11, a sludge pump 15, a motor 1 and a speed reducer 2, wherein two rows of sludge discharge pipes 10 are uniformly arranged on the bottom surface of the feed box 11 at intervals, two groups of guide rods 7 which are vertically arranged are arranged on the top surface of the feed box 11 in a sliding fit mode through guide sleeves 6, a reset spring 5 is sleeved on the upper portion of each guide rod 7, the lower end of each guide rod in the feed box 11 is connected with a top rod 8, ejector pins 9 are uniformly arranged below the bottom surface of each top rod 8 at intervals, and the ejector pins 9 are matched with the sludge discharge pipes 10 to work; two transmission shafts 3 are horizontally arranged on the top surface of the feed box 11 side by side through a bracket and a bearing seat 14, the transmission shafts 3 are driven by the motor 1 and the speed reducer 2 to rotate, two cams 4 are respectively arranged on each transmission shaft 3, and the rims of the cams 4 are contacted with the top ends of the guide rods 7; the other ends of the two transmission shafts are respectively provided with gears 16 which are meshed with each other, and the rotation directions of the two transmission shafts are opposite; the top surface of the material box 11 is connected with a sludge pump 15 through a sludge pipe 12, and the feed inlet of the sludge pump 15 is connected with a hopper 13.
After the equipment is started, the motor 1 and the speed reducer 2 start to work, the speed reducer 2 drives the transmission shaft 3 to start to rotate, meanwhile, the cam 4 and the gear 16 assembled on the transmission shaft correspondingly rotate, and the other driven shaft is driven to do reverse motion through the gear 12; the cam 4 rotates to drive the guide rod 7 to move downwards along the guide sleeve 6 and apply work to compress the return spring 5, meanwhile, the ejector rod 8 and the ejector pin 9 also move downwards, and the ejector pin 9 is ejected out of the sludge discharge pipe 10 to realize the through hole effect. When the cam 4 returns, the compression state of the spring 5 starts to be released, the guide rod 7, the ejector rod 8 and the ejector pin 9 are pushed back to the original position, and the reciprocating motion of the dredging device is realized. According to the material blocking frequency, the input frequency of the motor 1 is adjusted, the reciprocating motion frequency of the dredging device can be controlled, the blocking condition is avoided in advance, and the stable operation of equipment is guaranteed. When the interior of the material box 11 is blocked by hard objects, the motor 1 triggers the frequency converter to alarm when the load is abnormal, and feeds back a hard object blocking alarm signal to the system, and meanwhile, the frequency converter is automatically powered off to carry out overload protection on the system. After the power is off, workers can manually clean foreign matters through the access panel, and the foreign matters are reinstalled after the hard matters are cleaned, so that the hard matters are prevented from being blocked and the hardware of the equipment is prevented from being damaged.
